This automatically aligns the gear center during clamping, accurately positioning the gear and facilitating subsequent processing.

Description

Technical Field

[0001] This utility model belongs to the field of fixture technology and relates to a fixture for the production of clutch gear parts. Background Technology

[0002] The clutch is installed between the engine and the transmission. It is an assembly in the automotive transmission system that is directly connected to the engine. The gear parts on the clutch need to be clamped and processed using a fixture during the machining process, hence the use of a fixture.

[0003] A gear manufacturing tooling fixture disclosed in Chinese Patent CN220050315U includes a first mounting plate, a mounting box, a positioning component, a first slider, a clamping plate, a drive component, and an adjusting rod. The mounting box is fixedly disposed on the upper part of the first mounting plate. A slide rail is provided on the upper part of the mounting box. The positioning component is disposed at the center of the slide rail for positioning the gear. The first slider is slidably disposed on both sides of the mounting box. The top end of the first slider passes through the slide rail and extends to the outside of the mounting box where a clamping plate is fixedly disposed. The clamping plate is used to clamp and fix the gear.

[0004] The fixture clamps and fixes the gear by moving two clamping plates in opposite directions. Since the gear is fitted onto the positioning post, for gears with a large center hole diameter, there is a distance between the center hole of the gear and the outer surface of the positioning post after the gear is fitted onto the positioning post. If one of the clamping plates contacts the gear first when the two clamping plates move, it will push the gear to move, which can easily cause the center of the gear to shift and make the positioning inaccurate.

[0005] To address the aforementioned problems, this utility model proposes a fixture for the production of clutch gear parts. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a fixture for the production of clutch gear parts.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a support plate, a support base is fixedly provided at the bottom of the support plate, a turntable is rotatably provided at the middle of the support base, and four sliders are horizontally slidably provided on the support base. The four sliders are arranged in a circular array about the turntable, and each slider is hinged to the turntable with an arc-shaped connecting rod. Each slider is fixedly provided with a clamping block at its top, and the clamping block is slidably disposed on the top surface of the support plate.

[0008] Furthermore, four protrusions are uniformly and fixedly connected to the outer surface of the top of the support base, and the four protrusions are all fixedly connected to the bottom of the support plate. The turntable is rotatably disposed between the bottom surface of the support plate and the top surface of the middle part of the support base.

[0009] Furthermore, a motor is fixedly installed at the bottom of the support base, and the output shaft of the motor rotates upward through the support base, with the turntable coaxially fixedly sleeved on the output shaft of the motor.

[0010] Furthermore, the support base is provided with four convex grooves evenly distributed, and the four grooves correspond one-to-one with the four sliders. The shape of the sliders is adapted to the shape of the grooves, and the sliders are limited and slidably connected in the corresponding grooves.

[0011] Furthermore, a cylindrical positioning block is fixedly connected to the center of the top surface of the support plate, and the central axis of the positioning block is collinear with the central axis of the turntable; Each clamping block has an arc-shaped surface on the side closest to the positioning block, and a rubber pad is fixedly installed on each arc-shaped surface.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A fixture for producing clutch gear parts includes a support plate 1. Support columns are fixedly connected to the four corners of the bottom surface of the support plate 1, and a base plate is fixedly connected between two adjacent support columns. The base plate supports the support plate 1 and facilitates its installation.

[0019] A support base 6 is fixedly installed at the bottom of the support plate 1, and the support base 6 is located between four support columns. A turntable 9 is rotatably installed in the middle of the support base 6.

[0020] Four protrusions are evenly fixedly connected to the outer surface of the top of the support base 6, and all four protrusions are fixedly connected to the bottom of the support plate 1. This creates a distance between the middle of the support base 6 and the support plate 1. The turntable 9 is rotatably positioned between the bottom surface of the support plate 1 and the top surface of the middle part of the support base 6.

[0021] A motor 8 is fixedly mounted on the bottom of the support base 6, and the output shaft of the motor 8 rotates upward through the support base 6. A turntable 9 is coaxially fixedly sleeved on the output shaft of the motor 8. The turntable 9 is driven to rotate by the motor 8.

[0022] Four sliders 10 are horizontally slidably mounted on the support base 6, and the four sliders 10 are arranged in a circular array about the turntable 9. The turntable 9 is located between the four sliders 10.

[0023] The support base 6 has four evenly spaced convex grooves 7, each corresponding to one of the four sliders 10. The shape of the slider 10 matches the shape of the groove 7, and the slider 10 is slidably connected within the corresponding groove 7. The sliding of the slider 10 is positioned by the grooves 7.

[0024] Each slider 10 is hinged to the turntable 9 by an arc-shaped connecting rod 11. The four connecting rods 11 are also arranged in a circular array about the turntable 9.

[0025] Each slider 10 has a clamping block 3 fixedly installed on its top, and the clamping block 3 is slidably installed on the top surface of the support plate 1.

[0026] Each slider 10 has a connecting shaft 12 fixedly connected to the center of its top surface, and the connecting shaft 12 is vertically arranged. The clamping block 3 is fixedly connected to the top of the connecting shaft 12, so that the slider 10 drives the clamping block 3 to move through the connecting shaft 12.

[0027] The support plate 1 has four evenly spaced slots 5, which correspond one-to-one with four sliding grooves 7. The connecting shaft 12 slides through the corresponding slots 5. The clamping block 3 is positioned by the cooperation between the slots 5 and the connecting shaft 12.

[0028] The outer surface of the turntable 9 has an annular groove. One end of each connecting rod 11 is rotatably connected to the groove, and the other end of the connecting rod 11 is rotatably sleeved on the corresponding connecting shaft 12. When the turntable 9 rotates, it drives one end of the connecting rod 11 to move, and the other end of the connecting rod 11 pulls the connecting shaft 12 to move.

[0029] A cylindrical positioning block 2 is fixedly connected to the center of the top surface of the support plate 1. The central axis of the positioning block 2 is collinear with the central axis of the turntable 9. The gear is positioned on the top of the support plate 1 by the positioning block 2 to facilitate subsequent clamping operations.

[0030] Each clamping block 3 has an arc-shaped surface on the side closest to the positioning block 2, and a rubber pad 4 is fixedly installed on each arc-shaped surface. This allows the clamping block 3 to clamp the gear through the rubber pad 4, preventing excessive clamping force from damaging the gear. At the same time, the rubber pad 4 can deform to adapt to the shape of the gear.

[0031] Working principle: In use, move the gear parts on the clutch to the top of the support plate 1 so that the hole in the center of the gear fits onto the positioning block 2. At this time, the gear is located between the four clamping blocks 3.

[0032] Start motor 8, and the output shaft of motor 8 rotates clockwise. This drives turntable 9 to rotate, and turntable 9 drives one end of connecting rod 11 to move. The other end of connecting rod 11 pulls connecting shaft 12 to move, causing connecting shaft 12 to slide on slot 5 and move closer to turntable 9.

[0033] The connecting shaft 12 drives the slider 10 to slide within the groove 7, and simultaneously drives the clamping block 3 to slide on top of the support plate 1. This brings the four clamping blocks 3 closer together, and causes the rubber pad 4 to move closer to the gear.

[0034] If the rubber pad 4 comes into contact with the gear, the continued movement of the clamping block 3 will push the gear to move through the rubber pad 4. Because the gear has a certain weight, it slides on top of the support plate 1.

[0035] Until all the rubber pads 4 are in contact with the gear, the clamping blocks 3 continue to move, squeezing the rubber pads 4 and deforming them to fit the shape of the gear. Then, the gear is fixed by the cooperation of the four clamping blocks 3, and the four clamping blocks 3 automatically center the gear during the clamping process, so that the central axis of the gear is collinear with the central axis of the positioning block 2, so as to facilitate subsequent gear processing operations.

[0036] After the gears are machined, the output shaft of motor 8 reverses, driving turntable 9 to rotate. Turntable 9 then pushes connecting shaft 12 to move via connecting rod 11, causing connecting shaft 12 to move away from turntable 9.

[0037] The connecting shaft 12 drives the slider 10 and the clamping block 3 to move, causing the rubber pad 4 to leave the gear, thus enabling the gear to be removed.

[0038] When grinding gears, some debris will fall from the slot 5 into the slide groove 7. Through holes can be made at both ends of each slide groove 7, allowing the slider 10 to push the debris to the through holes as it moves, causing the debris to fall downwards. At the same time, the debris on the device needs to be cleaned regularly.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
