Adjusting the screw-cutting lathe 165

Adjusting the spindle bearings of a screw-cutting lathe 165

After some time, it may be necessary to adjust the mechanisms to ensure normal clearances and compensate for wear. Below are instructions for regulating individual mechanisms.

Spindle supports for screw-cutting lathe 165

The spindle of lathe 165 is mounted on 5 bearings:

• 16. Front bearing 4-3182140 - double-row radial roller bearing, with short cylindrical rollers, with a flat outer ring, with a tapered bore (1:12), accuracy class 4 (C)
• 15. Bearing 5-8144 - thrust ball bearing, designed for operation under axial load in units with low rotation speeds (2 pcs), accuracy class 5(A)
• 7. Bearing 12736 - radial roller bearing with short cylindrical rollers with a single-flanged outer ring and a double-flanged inner ring, accuracy class 0(N)
• 8. Rear bearing 5-3182132 - double-row radial roller bearing, with short cylindrical rollers, with a flat outer ring, with a tapered bore (1:12), accuracy class 5(A)

Spindle Bearing Adjustment

The bearings of the front spindle support must be adjusted in the following order (Fig. 21):

1. Remove the cartridge
2. Remove screws 1 and 2
3. Unscrew screw 3 and remove cracker 4
4. Loosen nut 5
5. Use nut 6 to pull off the inner race of the bearing for easier removal of the half rings 7
6. Unscrew the nut 6 from the half rings 7 and remove them from the groove
7. Determine the radial clearance in the bearing using an indicator. Place the indicator leg at the top point of the spindle flange and apply a load of 450 kg to the bottom point of the spindle flange. By tightening nut 5, bring the radial clearance to 0.015 mm. Using measuring tiles or lead spacers, measure the width of the groove for the half rings 7. Grind the half rings 7 to the size of the groove and install them.
8. Using nut 5, tighten the inner ring of the bearing and clamp the half rings 7
9. Screw the nut 6 onto the half rings 7 to prevent them from falling out and tighten it with locking screws 2 and 1
10. Use nut 8 to adjust the axial clearance of the ball thrust bearings
11. Insert the block 4 into the groove of nut 5 and tighten it with screw 3. The diametrical clearance of the rear spindle bearing is adjusted by nut 9 located on the outside of the headstock.

To do this, first remove the glass covering the end of the spindle, then loosen the locking screw 10 and tighten the nut 9.

After adjusting the bearing, screw 10 is locked again. The correctness of the adjustment can be established by checking the radial and axial runout of the spindle in accordance with the accuracy standards for the machine. When the gearing of the gears is turned off, the spindle should be free to turn by hand after adjusting the bearings.

Installing the headstock spindle axis

During transportation or during operation, the parallelism of the spindle axis relative to the bed guides may be disrupted. In this case, all the screws connecting the gearbox to the frame are loosened. The spindle axis is adjusted using screws 1, screwed into blocks 2, located under the gearbox on both sides and rigidly connected to the latter. After adjusting the spindle axis, the screws are tightened.

Transverse movement of the tailstock housing

Transverse movement of the tailstock body when turning cones or when installing the quill axis coaxially with the spindle axis is carried out by loosening and tightening two screws 1 located on both sides of the tailstock. When installing the tailstock into its original position, it is necessary to combine the marks marked on the plates of the tailstock body and the bridge from the rear end.

The gap in the guides of the cutting slide is adjusted by tightening the wedge 1 with screw 3, after which the position is fixed with screw 2.

Screw-cutting lathe DIP-500 (1M65)

The DIP-500 screw-cutting lathe began to be produced instead of the 165th line lathe. With its help, it became possible to process large-sized workpieces in small-scale and individual production. Due to its high reliability and quality of manufacture, the machine was exported.

Today, these models are not produced, but you can choose their modern analogues.

Description

The DIP-500 machine is a turning equipment that is universal; it can be used in various fields of industry for turning operations for manufacturing products. With its help, it is possible to perform the above work with normal accuracy (H) and high productivity. Over the entire period of operation, the machine has proven itself to be highly reliable due to the quality of manufacture and ease of maintenance, and also did not require high attention or special conditions during operation.

Description and purpose

The RS3 machine tool plant, Ryazan, was initially involved in the development and production of model 165. The beginning of industrial production dates back to 1953. Later, other enterprises in the country began producing the unit. The 165 screw-cutting lathe in its basic modification offered the ability to work with medium-weight parts, with a turning diameter of up to 1000 mm.

165 universal screw-cutting lathe is designed to perform basic operations. On it you can:

• process cylindrical workpieces, conical-shaped parts, work along a complex curved, shaped profile of a rotating surface;
• carry out operations both on the external surface of the workpiece and on the internal one;
• process workpieces of both large and medium dimensions;
• make cutting of modular type threads, metric, pitch, inch;
• work with high cutting speed indicators;
• use high-speed steel tools;
• process workpieces of a wide range of metals;
• use combined cutters with inserts made of hard alloys.

Model 165 provides high precision machining. This is achieved, not least, by the design characteristics. High rigidity, parametric parameters of the spindle, drive and carriage allow turning and other processing at high cutting speeds and a wide range of tools without reducing accuracy.

Modular threads, as well as other types, can be cut either mechanically, with a cutter, varying the feed rate and pitch, or manually, using a wide range of taps, dies, and other devices. The latter are installed on a quill that has a standard type of cone for installing clamping devices.

Design of sectional horizontal pump CNS 60-165

The main structural units of the pump are the casing and the rotor.

The housing includes suction and discharge line covers, guide vanes, front and rear brackets. The housings of the guide vanes, suction and discharge covers are tightened with coupling bolts.

The guide vane, ring (with sealing rings) and impeller form the pump section. The joints of the guide vane housings are sealed with rubber rings made of oil- and petrol-resistant rubber.

Due to the fact that the pump body consists of separate sections, it is possible, without changing the flow, to change the pressure by installing the required number of impellers and guide vanes with housings. In this case, only the length of the shaft and tie rods changes.

The pump rotor consists of a shaft on which impellers, a ring, a shaft jacket, a spacer sleeve, adjusting rings and a relief disk are installed. All parts on the shaft are tightened with a rotor nut.

The rotor is supported by two radial spherical bearings installed in the front and rear brackets in a sliding fit, allowing the rotor to move in the axial direction by the amount of the rotor “run-up”.

The bearing chambers are sealed with cuffs installed in the bearing caps.

The bracket is closed from the outside with a cover in which a rotor displacement control device is mounted.

Design Features

Any machine includes some standard components. They determine what functionality a particular type of equipment has.

bed

The bed acts as a load-bearing element. The remaining parts are attached to this part. Structurally, this part looks like two walls that connect to each other. Rigidity to a certain extent is given to it by the transverse elements that organize the connection. The machine is equipped with separate parts that move along the bed.

To solve this issue, special guides are provided.

• Three of the guides have a prism-shaped cross-section.
• One part is flat.

Headstock

The headstock is needed to simultaneously perform two functions:

1. The workpiece is fully supported while processing is in progress.
2. So that the part rotates in a certain way.

The front part of this equipment also contains handles responsible for controlling speeds. Thanks to this, the spindle can rotate at a certain frequency.

A special diagram is usually placed next to the handle. It is enough to study it once to understand when and what part is turned on.

The headstock in front houses a high-speed box, complemented by a rotating spindle assembly. Inside this part of the structure, special bearings can be used for rolling or sliding. The chuck of the device is fixed at the end of the spindle; a connection with threads is necessarily used in the process. This unit ensures that the part rotates in a certain way while processing is in progress.

To move the carriage on the machine, bed guides with a prismatic cross-section are used. This part must maintain certain properties such as accuracy and straightness. Neglecting such conditions will not allow you to get quality work in the end.

Tailstock

The machines accommodate tailstocks, available in different versions. It is also necessary to solve several problems:

• Fix parts with significant length.
• Attach various tools such as taps, drills, reamer etc.

The headstock in front fixes an additional center in the front part. It can be rotating or stationary.

If parts need to be processed quickly, a solution with a rotating rear center is relevant. The same applies to removing chips with a significant cross-section. Such circumstances lead to the following type of tailstock design:

1. Two bearings are placed in the quill hole.
2. One of them is front thrust, and the second is rear radial.
3. There is a bushing. Its internal part is bored to a cone.

The thrust ball bearing absorbs part of the axial loads associated with the machining process. The rear center is fixed using a tapered hole at the bushing. You can use a stopper to firmly fix the sleeve. This is relevant when it is necessary to secure other tools. Then the tool and other parts will not move, the owner forgets about the problems.

In some cases, the rear center of the headstocks remains stationary - when fastening, special plates are used, for the movement of which the guide part is responsible. A quill is installed in such a headstock, which requires a special nut when moving. Inside the quill there is a cone-shaped hole. Here is the location of two other components:

• Center of the machine.
• Shank from an axial tool.

The energy is transferred to the quill and nut when a special type of flywheel connected to the screw begins to move. Transverse movement of the quill is also permissible, which makes it possible to process parts with a flat body.

Caliper and carriage

The caliper makes it so that the tool holders move in any plane - inclined, transverse or longitudinal. Lathes allow you to communicate movement mechanically or manually. Studying the drawings of the calipers makes it clear how the tool moves along with the workpiece:

1. The longitudinal type direction involves the use of the same slide. This part of the machine is also called the carriage.
2. Accordingly, the transverse movement is carried out on the basis of a transverse slide. The rotating component of the structure is mounted for this purpose. Installation will not cause problems if the specified conditions are met.

The tool holder must be located above the support. Parts are developed for one place, or for several at once. The usual types of tool holders are a body with a slot, made in the shape of a cylinder. The working tool is installed in the slot. After this, fastening is carried out using a bolt.

The head with the cutter at the bottom is shaped like the letter T. Thanks to this type, the part fits into the groove without any problems. There are several options for mounting the tool holder.

Machine apron

Two couplings, fine-toothed type, are placed in the apron, due to which sets of carriages with calipers move in each of the axes. Each type of travel - along or across - is controlled by a separate handle. When turned on, the handles turn toward themselves, when turned off, away from themselves.

The apron is equipped with an additional locking device, which prevents the simultaneous activation of the feed from the roller and the lead screw. When the thread is cut from engagement with the rack, the working gear must be removed.

Gearbox

Moving the speed of the shaft with the lead screw is why a feed box is needed. The choice of specific numbers depends on the workpieces being processed and their own characteristics. The design can be described as follows:

• There is a gearbox inside.
• The gearbox itself contains several gears that switch with each other.
• The torque from the spindle is transmitted to the input shaft of the feed box through replaceable gears, which are also called a guitar.
• The usual location for the drive shaft is on the gearbox. The same goes for the screw.
• The apron transmits torque from previous parts.

Thanks to the transmission mechanism, several operating options can be allowed:

1. You can manually move the cutter in relation to the workpiece.
2. Regulation by feed amount.
3. Reversal at the spindle and feed occur simultaneously.
4. Reversing the feed while maintaining the previous position of the spindle.
5. The feed is turned on and off without the user touching the spindle.

For feeds, spindle mechanisms become the main sources of movement.

Replacement gears

The headstock output shaft will not transfer motion to the transmission input shaft without replacement gears. By using different gear combinations, it is easy to make adjustments to different threads. To obtain the main result, several types of feeds are used:

Each option has its own special provisions.

The gears are secured with nuts and a washer. The number of teeth along with the module is displayed due to the end part of the replaceable parts. They can have different clearances depending on the results you want to achieve. The main thing is to regularly lubricate the gears and bushings, then they will last as long as possible. It is convenient to service any design options through the oil cap.

Ammo

During turning operations, the rotation speed of the part is very high. Therefore, cartridges must comply with special operating requirements. At the machine they are mounted on the front spindle headstock. The latter is connected to the electric motor using a gearbox and transfer case.

Studying the technical parameters of cartridges is mandatory in order to make the right choice for each specific case. In many ways, the parameters themselves are determined by the lathe and the operations that are currently being carried out.

When selecting, you should pay attention to the following indicators:

1. Rotational frequency limits for chucks.
2. Body hole diameter. Rods are installed in it.
3. Characteristics of the product being processed. The method of fixation - with direct or reverse cams - determines the maximum and minimum size range. It is necessary to take into account what the mass of the workpiece may be.
4. Diameters to do the job. This applies to the external indicator, for the connecting belt, location, size of holes for fasteners.
5. Design. It determines how the workpiece will be fixed, how many clamping elements are used, how the parts are arranged, and whether several can be installed at once.

Cartridges are complex technological structures.

Lunettes

A lunette is an additional device for machine tools. This is the main or secondary support for working with workpieces. The tool adds stability and provides additional protection from damage.

Operating principle of the sectional horizontal pump CNS 60-165

The operation of the pump is based on the interaction of the rotating impeller blades and the pumped liquid.

Rotating, the impeller imparts a circular motion to the fluid located between the blades. Due to the resulting centrifugal force, the liquid from the center of the wheel moves to the external outlet, and the vacated space is again filled with liquid coming from the suction pipe under the influence of the created vacuum.

Having left the impeller of the first section, the liquid enters the channels of the guide vane and then into the second impeller with the pressure created in the first section, from where it enters the third impeller with increased pressure created in the second section, etc.

The liquid released from the last impeller flows through the guide vane into the discharge cover and from it into the discharge pipeline.

During pump operation, due to water pressure on the unequal area lateral surfaces of the impellers, an axial force arises, which tends to displace the pump rotor towards the suction side.

To balance the axial force, the pump is equipped with an unloading device, consisting of an unloading disk, an unloading ring and bushing, and a spacer bushing.

The liquid from the last stage passes through the annular gap between the unloading bushing and the spacer bushing and presses on the unloading disk with a force equal to the sum of the forces acting on the impellers, but directed towards the discharge. The pump rotor is balanced, and equal forces are established automatically.

The liquid leaving the unloading chamber cools the oil seal on the pressure side.

The suction side seal is flushed with liquid supplied under pressure from the suction line. The liquid, passing through the shaft jacket through the stuffing box, prevents air from being sucked into the pump and at the same time cools the stuffing box. Most of the liquid passes through the gap between the shaft jacket and the hydraulic seal sleeve into the suction cavity, some passes between the shaft jacket and the oil seal on the suction side, cooling it, the rest comes out through the fitting.

The tightening of the stuffing box should allow the pumped liquid to leak out between the shaft and the stuffing box packing in an amount of 5-15 l/h. A smaller number indicates that the oil seal is over-tightened, which increases friction losses and accelerates wear of the shaft jacket and rotor nut.

The pump rotor is driven by an electric motor connected to the pump through an elastic sleeve-finger coupling, consisting of two coupling halves (pump and electric motor) and fingers with rubber bushings.

The direction of rotation of the pump rotor is clockwise when viewed from the electric motor.

The pump and electric motor are installed on a common foundation plate so that there is a gap of 10 mm between the coupling halves when the pump rotor is shifted completely towards the suction side.

The unit's electric motor must be grounded before operation.

The CNS pump has self-priming capabilities. This condition is achieved by installing a valve inside the pump.

As part of the central nervous system pumping unit, as a rule, general industrial asynchronous electric motors are installed on the pump. Most often, a three-phase asynchronous motor with a squirrel-cage rotor is used for these purposes.

Pumps are manufactured with both stuffing box and mechanical seals. Leaks through mechanical seals - according to the technical documentation for mechanical seals.

The pump support brackets are made of cast iron, the material of the flow part of the pumps is TsNS SCh-20, Steel 35L, the shaft is steel 40x, the guide vane, ring and body of the guide vane, the oil seal bushing is made of press material AG-4V. The pump shaft is sealed using an stuffing box packing with a cross-section of 10 mm.

CNS pumps operate stably and for a long time with a headwater of 2-6 m. In the absence of headwater at the inlet, cavitation quickly destroys these high-speed pumps. When installing them to pump water with a temperature of more than 45°C, it is necessary to increase the pressure at the inlet to the pump.
