Description

Technical Field

[0001] This utility model relates to the field of air spring fixing technology, specifically to a production fixing fixture for automotive shock absorber air springs. Background Technology

[0002] With the rapid development of the automotive industry, automotive air springs play a crucial role in the comfort and stability of vehicle driving. A key issue in the production process of automotive air springs is how to stably and precisely fix them.

[0003] Currently, the common automotive shock absorber air spring production fixtures on the market have many shortcomings. On the one hand, traditional fixtures can only adapt to air springs of specific sizes. For air springs of different diameters, different fixtures need to be changed, which not only increases production costs but also reduces production efficiency. On the other hand, during the clamping process, due to the lack of an effective preliminary positioning device, the air spring is prone to positional deviation, leading to production quality problems. At the same time, a lot of time is also needed to adjust the position. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a production fixing fixture for automotive shock absorber air springs, comprising: a clamping device; a positioning device, wherein the outer wall of the positioning device is fixedly connected to the outer wall of the clamping device; the positioning device includes a positioning post, the outer wall of the positioning post has a positioning groove, the inner wall of the positioning groove is slidably connected to a support plate, the outer wall of the support plate is symmetrically fixedly connected to a compression spring, the top outer wall of the support plate is fixedly connected to a positioning plate, the outer wall of the positioning plate is fixedly connected to a pull plate, the outer wall of the positioning plate has a limit groove, the top outer wall of the positioning post is fixedly connected to a limit frame, the inner wall of the limit frame is slidably connected to a slide plate, the bottom outer wall of the slide plate is fixedly connected to a pressure spring, and the top outer wall of the slide plate is fixedly connected to a limit block and a button.

[0005] Preferably, the limiting blocks are arranged in an array along the outer wall of the slide plate; the outer walls of the limiting blocks and buttons are slidably connected to the inner wall of the top of the limiting frame; the outer wall of the compression spring on the side away from the support plate is fixedly connected to the inner wall of the positioning groove; the outer wall of the limiting blocks is slidably connected to the inner wall of the limiting groove; the positioning grooves are arranged in a ring array along the axial center point of the positioning posts; the initial state of the positioning posts is as follows: Figure 7As shown, pressing the button causes the slide plate to slide downwards along the inner wall of the limiting frame. The pressure spring fixedly connected to the outer wall at the bottom of the slide plate is compressed. The limiting block fixedly connected to the outer wall at the top of the slide plate moves downwards with the slide plate and slides away from the limiting groove on the positioning plate. Because the positioning plate is fixedly connected to the support plate, when the limiting block separates from the limiting groove, the support plate slides outwards along the positioning groove due to the elastic force released by the compressed spring. At this time, the positioning device is as follows: Figure 4 As shown.

[0006] Preferably, the clamping device includes a base, the outer wall of the top of the base is symmetrically provided with sliding grooves, the inner wall of the sliding groove is slidably connected to a slider, the inner wall of the slider is threadedly connected to a bidirectional threaded rod, the outer wall of the bidirectional threaded rod away from the slider is fixedly connected to a throttle, the outer wall of the top of the slider is fixedly connected to a clamping block, and the outer wall of the clamping block is fixedly connected to a rubber pad.

[0007] Preferably, the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the base, and the outer wall of the bottom of the clamping block is slidably connected to the outer wall of the top of the base. Rotating the handle drives the bidirectional threaded rod to rotate. Since the outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the base, the rotation of the bidirectional threaded rod will cause the slider connected to it to slide in the groove. Because the two threads of the bidirectional threaded rod are opposite in direction, when the handle is rotated, the two sliders will move closer to each other or further away at the same time.

[0008] Preferably, the outer wall of the bottom of the positioning column is fixedly connected to the outer wall of the top of the base, the outer wall of the bottom of the support plate is slidably connected to the outer wall of the top of the base, and the outer wall of the bottom of the positioning column is fixedly connected to the outer wall of the top of the base, thus ensuring the stability of the positioning column.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting a clamping device, the bidirectional threaded rod allows the clamping block to be adjusted according to the size of the air spring, which can accommodate air springs of different diameters. The clamping block and rubber pad in the clamping device can fit tightly against the air spring shell, which not only plays an anti-slip role and prevents the air spring from sliding during the production process, but also protects the surface of the air spring sleeve from damage, ensuring the appearance quality of the product.

[0011] 2. This utility model, by setting up a positioning device, ensures that the air spring is accurately positioned before clamping by the positioning column and positioning plate in the positioning device, providing a good foundation for subsequent production processes. The cooperation between the support plate and the compression spring can adapt to air springs of different sizes. Whether it is a shock-absorbing air spring for small cars or large cars, this fixture can provide stable clamping and positioning. At the same time, through the preliminary positioning design, production quality problems caused by position deviation during clamping are avoided, and the time for adjusting the position is also reduced.

Example

[0021] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a production fixing fixture for automotive shock absorber air springs, comprising: a clamping device 1; a positioning device 2, the outer wall of the positioning device 2 being fixedly connected to the outer wall of the clamping device 1; the positioning device 2 comprising a positioning post 21, the outer wall of the positioning post 21 having a positioning groove 22, the inner wall of the positioning groove 22 being slidably connected to a support plate 24, the outer wall of the support plate 24 being symmetrically fixedly connected to a compression spring 25, the top outer wall of the support plate 24 being fixedly connected to a positioning plate 26, the outer wall of the positioning plate 26 being fixedly connected to a pull plate 27, the outer wall of the positioning plate 26 having a limit groove 28, the top outer wall of the positioning post 21 being fixedly connected to a limit frame 29, the inner wall of the limit frame 29 being slidably connected to a slide plate 291, the bottom outer wall of the slide plate 291 being fixedly connected to a pressure spring 292, and the top outer wall of the slide plate 291 being fixedly connected to a limit block 293 and a button 294.

[0022] Limiting blocks 293 are arranged in an array along the outer wall of the slide plate 291. The outer walls of limiting blocks 293 and buttons 294 are slidably connected to the inner wall of the top of the limiting frame 29. The outer wall of the compression spring 25 on the side away from the support plate 24 is fixedly connected to the inner wall of the positioning groove 22. The outer wall of the limiting blocks 293 is slidably connected to the inner wall of the limiting groove 28. The positioning groove 22 is arranged in a ring along the central point of the positioning post 21. The initial state of the positioning post 21 is as follows: Figure 7 As shown, pressing button 294 causes the slide plate 291 to slide downwards along the inner wall of the limiting frame 29. The pressure spring 292, which is fixedly connected to the outer wall at the bottom of the slide plate 291, is compressed. The limiting block 293, which is fixedly connected to the outer wall at the top of the slide plate 291, moves downwards with the slide plate 291 and slides away from the limiting groove 28 on the positioning plate 26. Because the positioning plate 26 is fixedly connected to the support plate 24, when the limiting block 293 separates from the limiting groove 28, the support plate 24 slides outwards along the positioning groove 22 by the elastic force released by the compression spring 25. At this time, the positioning device 2 functions as follows: Figure 4 As shown.

[0023] The clamping device 1 includes a base 11. The outer wall of the top of the base 11 is symmetrically provided with a sliding groove 12. The inner wall of the sliding groove 12 is slidably connected to a slider 13. The inner wall of the slider 13 is threadedly connected to a bidirectional threaded rod 14. The outer wall of the bidirectional threaded rod 14 away from the slider 13 is fixedly connected to a throttle 15. The outer wall of the top of the slider 13 is fixedly connected to a clamping block 16. The outer wall of the clamping block 16 is fixedly connected to a rubber pad 17.

[0024] The outer wall of the bidirectional threaded rod 14 is rotatably connected to the inner wall of the base 11, and the outer wall of the bottom of the clamping block 16 is slidably connected to the outer wall of the top of the base 11. Rotating the handle 15 causes the bidirectional threaded rod 14 to rotate. Since the outer wall of the bidirectional threaded rod 14 is rotatably connected to the inner wall of the base 11, the rotation of the bidirectional threaded rod 14 will cause the slider 13, which is threaded to it, to slide in the groove 12. Because the two threads of the bidirectional threaded rod 14 are opposite in direction, when the handle 15 is rotated, the two sliders 13 will move closer to each other or further away at the same time.

[0025] The outer wall at the bottom of the positioning post 21 is fixedly connected to the outer wall at the top of the base 11, the outer wall at the bottom of the support plate 24 is slidably connected to the outer wall at the top of the base 11, and the outer wall at the bottom of the positioning post 21 is fixedly connected to the outer wall at the top of the base 11, thus ensuring the stability of the positioning post 21.

[0026] Working principle: When clamping and positioning are required during the air spring production process, the air spring is first placed on the positioning post 21 of the positioning device 2. The outer wall of the bottom of the positioning post 21 is fixedly connected to the outer wall of the top of the base 11, ensuring the stability of the positioning post 21. The initial state of the positioning post 21 is as follows: Figure 7 As shown, next, button 294 is pressed. Button 294 causes the slide plate 291 to slide downwards along the inner wall of the limiting frame 29. The pressure spring 292, which is fixedly connected to the outer wall of the bottom of the slide plate 291, is compressed. The limiting block 293, which is fixedly connected to the outer wall of the top of the slide plate 291, moves downwards with the slide plate 291 and slides away from the limiting groove 28 on the positioning plate 26. Because the positioning plate 26 is fixedly connected to the support plate 24, when the limiting block 293 separates from the limiting groove 28, the support plate 24 slides outwards along the positioning groove 22 by the elastic force released by the compression spring 25, so that the outer wall of the support plate 24 contacts the inner wall of the air spring sleeve for initial positioning, ensuring accurate positioning before clamping. At this time, the positioning device 2 is as follows: Figure 4 As shown.

[0027] Next, rotate the handle 15 on the clamping device 1 to drive the bidirectional threaded rod 14 to rotate. Since the outer wall of the bidirectional threaded rod 14 is rotatably connected to the inner wall of the base 11, the rotation of the bidirectional threaded rod 14 will cause the slider 13 connected to it to slide in the slide groove 12. Since the threads on both sides of the bidirectional threaded rod 14 are opposite, when the handle 15 is rotated, the two sliders 13 will move towards the middle at the same time. When the sliders 13 move towards the middle, they will drive the clamping block 16 fixedly connected to its top to move towards the middle. The rubber pad 17 on the outer wall of the clamping block 16 contacts the outer shell of the air spring. The relative movement of the two clamping blocks 16 achieves the clamping and fixing of the air spring sleeve. At the same time, the rubber pad 17 can play the role of anti-slip and protecting the surface of the air spring sleeve.

[0028] Conversely, when the air spring sleeve needs to be disassembled, flip the handle 15, and move the clamping block 16 outward along the slide groove 12 via the double-threaded rod 14 to release the air spring sleeve. Then, pull the air spring sleeve upward along the support plate 24, and pull the pull plate 27. The pull plate 27 drives the positioning plate 26 to move towards the limiting frame 29. The positioning plate 26 drives the support plate 24 to slide in the positioning groove 22 opened on the outer wall of the positioning post 21. The compression spring 25 symmetrically fixedly connected to the outer wall of the support plate 24 is compressed and stored, providing the support plate 24 with the force for the air spring sleeve to reset next time. As the positioning plate 26 moves and contacts the outer wall of the limiting block 293, the limiting block 293 is squeezed downward through its inclined surface, and at the same time, the sliding plate 291 slides downward on the inner wall of the limiting frame 29. The pressure spring 292 fixedly connected to the outer wall of the bottom of the sliding plate 291 is compressed again. When the limiting block 293 and the limiting groove 28 opened on the outer wall of the positioning plate 26 are in contact, the limiting plate 293 and the limiting plate 293 slide downward along the inner wall of the limiting frame 29. During alignment, under the action of the pressure spring 292, the limiting block 293 slides into the limiting groove 28, thereby fixing the positioning plate 26 and restoring it to its original position. Figure 7 The initial state is shown.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
