AI Technical Summary
Existing automotive parts processing positioning devices are prone to deformation of thin-walled plastic parts when the clamping force is too great.
The positioning assembly consists of a threaded rocker, an L-shaped sliding plate, a telescopic rod, and an anti-slip block. The threaded rocker drives the threaded sleeve and connecting column to slide, which in turn moves the L-shaped sliding plate and the positioning plate. The rubber anti-slip block and spring provide rebound force to avoid excessive clamping force, and the limit plate and limit teeth prevent deformation.
It effectively prevents thin-walled automotive parts from deforming during the positioning process, ensuring the accuracy and stability of subsequent processing and avoiding damage to plastic parts caused by excessive clamping.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a processing and positioning device for automotive parts. Background Technology
[0002] A machining positioning device for automotive parts is a tooling device used to fix and precisely position automotive parts during processing, ensuring that the parts are accurately and stably positioned during processing, thereby improving processing accuracy and efficiency. When using it, a suitable positioning device should be selected according to the shape of the part and processing requirements. It typically includes components such as clamps, locating pins, and V-blocks. During operation, the part is first placed on the reference surface of the positioning device, and the part is fixed in place using clamps or locating pins to ensure that its position will not move during processing, and then processing can begin. After use, the device should be cleaned and its positioning accuracy checked, and regular maintenance should be performed to ensure its performance.
[0003] When processing automotive parts, fixtures are used to position them. Common positioning devices are electrically driven, such as motors, cylinders, and electric push rods. However, when processing some automotive parts, there are some thin-walled plastic parts. If the clamping force of the equipment is too large when positioning such parts, for example, by using cylinders or motors for fixing, it is easy for the fixture to exert too much clamping force on the surface of the part, causing the part to deform.
[0004] In view of this, we propose a machining positioning device for automotive parts. Utility Model Content
[0005] The purpose of this utility model is to provide a processing and positioning device for automotive parts, which solves the problem of excessive clamping force causing deformation of automotive parts with thin walls when positioning them.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A processing and positioning device for automotive parts includes a processing table and a support. The processing table is located inside the support and is fixedly connected to it. It also includes a positioning component to prevent deformation of thin-walled automotive parts during positioning. The positioning component includes a threaded rocker arm that passes through the processing table and is rotatably connected to it. A threaded sleeve is threaded through and connected to the threaded rocker arm. A connecting post is fixedly connected to the top surface of the threaded sleeve. The connecting post passes through the processing table and is slidably connected to it. An L-shaped sliding plate is fixedly connected to the top surface of the connecting post. A positioning plate is slidably connected to the top surface of the L-shaped sliding plate. A telescopic rod is slidably connected to the inner side of the positioning plate. An anti-slip block is fixedly connected to the top end of the telescopic rod. There are two sets of L-shaped sliding plates, symmetrically arranged about the center line of the processing table.
[0008] Preferably, a spring is sleeved on the outer side of the telescopic rod, one end of the spring is fixedly connected to the bottom surface of the anti-blocking block, and the other end of the spring is fixedly connected to the top surface of the positioning plate.
[0009] Preferably, the telescopic rod passes through the L-shaped sliding plate and is slidably connected, and a connecting plate is fixedly connected to the bottom surface of the telescopic rod.
[0010] Preferably, guide blocks are fixedly connected to both sides of the connecting plate, and a guide groove is provided on the inner side of the processing table. The guide groove is an inclined groove with both ends higher than the middle. The guide blocks are inserted into the inner side of the guide groove.
[0011] Preferably, a limiting plate is hinged to the bottom surface of the connecting plate, and the side of the limiting plate near the connecting column is in contact with the surface of the connecting column.
[0012] Preferably, a torsion spring is fixedly connected to the surface of the limiting plate, and the end of the torsion spring away from the limiting plate is fixedly connected to the bottom surface of the connecting plate.
[0013] Preferably, a limiting strip is fixedly connected to the inner side of the processing table, and a limiting tooth is fixedly connected to the top surface of the limiting strip.
[0014] By means of the above technical solution, this utility model provides a processing and positioning device for automotive parts.
[0015] It has at least the following beneficial effects:
[0016] 1. In this utility model, the connecting plate moves together with the L-shaped sliding plate via the telescopic rod. Meanwhile, the guide block on the side of the connecting plate is located in an inclined V-shaped guide groove. As the guide block slides along the guide groove, the connecting plate gradually pulls the telescopic rod downwards. The telescopic rod then pulls the anti-slip block to fit against the surface of the automotive parts. Simultaneously, as the connecting plate moves downwards, it also moves the limiting plate downwards. The side of the limiting plate closest to the connecting post fits against the connecting post, limiting the limiting plate and preventing it from rotating towards the connecting post. As the limiting plate descends, it is blocked by the limiting teeth on the limiting strip, thus creating resistance and preventing the operator from rotating the threaded rocker. This avoids excessive clamping force from causing deformation of thin-walled automotive parts, which could affect subsequent processing.
[0017] 2. This utility model uses rubber material for the anti-slip block. When the connecting plate moves down, it can drive the limiting plate to move down together. The side of the limiting plate close to the connecting column is in contact with the connecting column, so that the tough anti-slip block has a certain rebound force while contacting the car parts. This avoids the anti-slip block from contacting the car parts too tightly, which could cause vibration during subsequent processing and damage to the car parts. Attached Figure Description

[0025] 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.
[0026] A machining positioning device for automotive parts, such as Figure 1 - Figure 5As shown, the system includes a processing table 1 and a support 3. The processing table 1 is located inside the support 3 and is fixedly connected to the support 3. It also includes a positioning assembly 2 to prevent extrusion deformation when positioning thin-walled automotive parts. The positioning assembly 2 includes a threaded rocker arm 21, which passes through the processing table 1 and is rotatably connected to it. A threaded sleeve 22 is threaded through and connected to the threaded rocker arm 21. A connecting post 23 is fixedly connected to the top surface of the threaded sleeve 22. The connecting post 23 passes through the processing table 1 and is slidably connected to it. An L-shaped sliding plate 24 is fixedly connected to the top surface of the connecting post 23. The top surface of the slide plate 24 is slidably connected to the positioning plate 25. The screw sleeve 22 is driven to move axially along the screw rocker 21 by rotating the screw rocker 21. Since the screw sleeve 22 and the processing table 1 are slidably connected through the connecting column 23, the linear movement of the screw sleeve 22 drives the connecting column 23 and the L-shaped slide plate 24 fixed at its top to move synchronously. When the L-shaped slide plate 24 moves, it will drive the positioning plate 25 to move together. The inner side of the positioning plate 25 is slidably connected to the telescopic rod 26. The top of the telescopic rod 26 is fixedly connected to the anti-slip block 27. There are two sets of L-shaped slide plates 24, and the two sets of L-shaped slide plates 24 are symmetrically arranged with the center line of the processing table 1 as the axis of symmetry. A spring 28 is fitted on the outer side of the telescopic rod 26. One end of the spring 28 is fixedly connected to the bottom surface of the anti-slip block 27. The anti-slip block 27 is made of rubber. As the connecting plate 29 moves downward, it can drive the limiting plate 211 to move downward as well. The side of the limiting plate 211 closest to the connecting post 23 is in contact with the connecting post 23, so that the tough anti-slip block 27 has a certain rebound force while contacting the automotive parts, avoiding excessive pressure from the anti-slip block 27 on the automotive parts, which could cause damage to the automotive parts due to vibration during subsequent processing. The other end of the spring 28 is fixedly connected to the top surface of the positioning plate 25. The telescopic rod 26 passes through the L-shaped sliding plate 24 and is slidably connected. The bottom surface of the telescopic rod 26 is fixedly connected to the connecting plate 29. The telescopic rod 26 drives the anti-slip block 27 and the connecting plate 29 to move together. As the positioning plate 25 moves with the L-shaped sliding plate 24, it gradually fits into the automotive parts, performing initial positioning of the automotive parts. Guide blocks 210 are fixedly connected to both sides of the connecting plate 29. A guide groove 213 is provided on the inner side of the processing table 1. The guide groove 213 is an inclined groove, with both ends higher than the middle. The guide blocks 210 are inserted into the inner side of the guide groove 213. A limit plate 211 is hinged to the bottom surface of the connecting plate 29. As the limit plate 211 gradually descends, it will be blocked by the limit teeth 215 on the limit strip 214, thus encountering resistance and preventing the operator from rotating the threaded rocker 21. The side of the limit plate 211 closest to the connecting column 23 is in contact with the surface of the connecting column 23. A torsion spring 212 is fixedly connected to the surface of the limit plate 211. The end of the torsion spring 212 away from the limit plate 211 is fixedly connected to the bottom surface of the connecting plate 29.A limiting strip 214 is fixedly connected to the inner side of the processing table 1. A limiting tooth 215 is fixedly connected to the top surface of the limiting strip 214. As the connecting plate 29 moves down, it can drive the limiting plate 211 to move down together. The side of the limiting plate 211 close to the connecting post 23 is in contact with the connecting post 23, so that the connecting post 23 limits the limiting plate 211, thus preventing the limiting plate 211 from rotating in the direction of the connecting post 23. As the limiting plate 211 gradually descends, it will be blocked by the limiting tooth 215 on the limiting strip 214. Thus, it will be subject to resistance, and the operator will no longer be able to rotate the threaded rocker 21, avoiding excessive force from the clamping of the machine, which could cause deformation of some thin-walled automotive parts.
[0027] In use, the operator of this utility model provides a machining positioning device for automotive parts. The operator rotates a threaded rocker arm 21 to drive a threaded sleeve 22 to move axially along the threaded rocker arm 21. Since the threaded sleeve 22 and the machining table 1 are slidably connected via a connecting post 23, the linear movement of the threaded sleeve 22 causes the connecting post 23 and the L-shaped sliding plate 24 fixed at its top to move synchronously. As the L-shaped sliding plate 24 moves, it causes the positioning plate 25 to move as well, and through a telescopic rod 26, it causes the anti-slip block 27 and the connecting plate 29 to move together. As the positioning plate 25 moves with the L-shaped sliding plate 24, it gradually conforms to the automotive part, performing initial positioning. Simultaneously, as the connecting plate 29 moves with the L-shaped sliding plate 24 via the telescopic rod 26, the guide block 210 on the side of the connecting plate 29 is located at an inclined V-shaped guide. Within the groove 213, as the guide block 210 slides along the guide groove 213, the connecting plate 29 gradually pulls the telescopic rod 26 downward. The telescopic rod 26 then pulls the anti-slip block 27 to fit against the surface of the automotive parts. Simultaneously, as the connecting plate 29 moves downward, it drives the limiting plate 211 to move downward as well. The side of the limiting plate 211 closest to the connecting post 23 fits against the connecting post 23, thus limiting the limiting plate 211 and preventing it from rotating towards the connecting post 23. As the limiting plate 211 gradually descends, it is blocked by the limiting teeth 215 on the limiting strip 214, thus encountering resistance and preventing the operator from rotating the threaded rocker 21. This avoids excessive clamping force from the equipment, which could deform some thin-walled automotive parts and affect subsequent processing.
[0028] The anti-slip block 27 is made of rubber. As the connecting plate 29 moves downward, it can drive the limiting plate 211 to move downward as well. The side of the limiting plate 211 closest to the connecting post 23 fits against the connecting post 23, so that the tough anti-slip block 27 can have a certain rebound force while contacting the automotive parts. This prevents the anti-slip block 27 from contacting the automotive parts too tightly, which could cause damage to the automotive parts due to vibration during subsequent processing.
