Description

Technical Field

[0001] This utility model relates to the field of brake shoe positioning technology, specifically a positioning device for brake shoe production. Background Technology

[0002] Brake shoes are a core component of automotive braking systems, composed of a composite of friction material and a metal backing plate. They achieve deceleration by generating friction through contact with the brake drum, and their structural precision directly affects braking performance and safety. During production, brake shoes undergo multiple processes such as stamping and riveting. Deviations in the assembly positions of various components can easily lead to uneven friction, abnormal noise, and other problems. Therefore, precise fixing is achieved through positioning devices to provide a stable benchmark for subsequent processing.

[0003] However, existing brake pad clamping and positioning devices have technical defects: First, most clamps have a fixed clamping angle, while brake pads are arc-shaped and have irregular side shapes, making it difficult to fully fit with the side during clamping, resulting in insufficient stability and firmness of clamping and positioning; Second, brake pads of different specifications have large differences in thickness, and existing clamps cannot be adjusted according to the thickness. If the clamp height is too high, it may cover the surface of the brake pad and affect subsequent processing operations; if the height is too low, it cannot form an effective clamp with the side, further reducing positioning stability. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for brake pad production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for brake pad production, comprising a placement table, a groove provided on the placement table, a vertical plate provided in the groove via a moving mechanism, a support plate provided in the vertical plate via a rotating component, and a clamping component provided in the support plate via an adjusting mechanism, the clamping component being used for clamping and positioning the brake pads.

[0006] Preferably, in order to facilitate the movement and adjustment of the vertical plate and to facilitate the clamping and positioning of the brake shoes with the clamping assembly, the moving mechanism includes an electric push rod set in the slide groove, and a slider is provided at the output end of the electric push rod. The slider slides in the slide groove, and the top of the slider is fixedly connected to the vertical plate.

[0007] Preferably, in order to ensure stability during movement and to serve as a guide and limiter, limit blocks are symmetrically arranged on both sides of the slider, and a limit groove matching the limit blocks is opened on the inner wall of the slide groove.

[0008] Preferably, in order to rotate and adjust according to the shape of the brake shoe side during the clamping and positioning process, so as to ensure that the clamping assembly fits better with the side and thus ensures stable and firm clamping and positioning, the rotating assembly includes a rotating groove opened on the side wall of the vertical plate, and a rotating component is horizontally rotatably arranged in the rotating groove, and the end of the rotating component is fixedly connected to the support plate.

[0009] Preferably, in order to clamp and position the brake pads and facilitate subsequent processing and production, the clamping assembly includes a bottom anti-slip pad set on the support plate, a clamping plate set on the support plate, and a side anti-slip pad set on the inner arc surface of the clamping plate.

[0010] Preferably, in order to facilitate the adjustment of the height of the clamping plate according to the thickness of the brake pads, thereby ensuring the clamping and positioning effect on the side without affecting subsequent processing, the adjustment mechanism includes an insertion groove on the support plate, the insertion groove is inserted into the support plate, and threaded holes are symmetrically opened on both sides of the insertion groove. A fixing bolt is engaged in the threaded hole through the thread, the fixing bolt abuts against the side wall of the support plate, and a washer is also provided on the outside of the fixing bolt.

[0011] Preferably, in order to guide and limit the movement and prevent slippage, the end of the support plate near the vertical plate is symmetrically provided with guide posts, and the side wall of the insertion slot near the vertical plate is provided with a guide groove that matches the guide posts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) Through the coordinated design of the moving mechanism and the slide, the vertical plate spacing can be flexibly adjusted to adapt to the shape characteristics of different specifications of brake shoes, and to achieve precise positioning and clamping, providing a stable foundation for subsequent processing. The rotating component gives the tray angle adjustment capability, so that the clamping component can automatically fit the irregular shape of the arc-shaped side of the brake shoe, significantly improving the firmness and stability of clamping and positioning. The double anti-slip structure of the bottom and side effectively increases the friction force, avoids displacement during processing, and ensures the processing accuracy of the braking components. (2) The adjustment mechanism can quickly adapt to the clamping requirements of brake pads of different thicknesses by using plug-in clamping plates and fixing bolts. This avoids both excessive height affecting operation and excessive height causing clamping failure, achieving a balance between adaptive adjustment and stable positioning. The guide design of the guide post and guide groove provides precise limit during the adjustment of the clamping plate height, preventing slippage and ensuring the convenience and reliability of the adjustment operation.

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides an embodiment of a positioning device for brake pad production, including a placement platform 11 with sliding grooves 12. The number of sliding grooves 12 can be three or four sets, preferably three sets. Figure 1 As shown, a clamping mechanism is used to conveniently clamp and position the brake pads, facilitating subsequent production and processing. A vertical plate 15 is installed within the slide groove 12 via a moving mechanism. A support plate 21 is mounted on the vertical plate 15 via a rotating assembly. The moving mechanism includes an electric push rod 13 installed within the slide groove 12. A slider 14 is installed at the output end of the electric push rod 13. The slider 14 slides within the slide groove 12, and its top end is fixedly connected to the vertical plate 15. Limiting blocks 17 are symmetrically arranged on both sides of the slider 14. A limiting groove 16 matching the limiting block 17 is formed on the inner wall of the slide groove 12. When the slider 14 slides within the slide groove 12, the limiting block 17 is positioned within the limiting groove. The movement within the groove 16 serves as a guide and limit, while the electric push rods 13 within the three sets of sliding grooves 12 move and extend independently, allowing for adaptive adjustment according to the shape of the brake pads for better clamping and positioning. The rotating assembly includes a rotating groove 22 on the side wall of the vertical plate 15, with a rotating component 23 horizontally rotatable within the rotating groove 22. Without external force, the rotating component 23 will not rotate within the rotating groove 22. The end of the rotating component 23 is fixedly connected to the support plate 21, and can rotate under force during contact with the brake pads, allowing the clamping assembly on the support plate 21 to better fit against the side of the brake pads, ensuring effective clamping and positioning.

[0017] Please see Figures 1-4 To facilitate clamping and positioning of brake pads, and to adjust the height of the clamping plate 31 according to different brake pad thicknesses to ensure effective clamping and positioning of the sides, the clamping assembly includes a bottom anti-slip pad 32 mounted on the support plate 21. The support plate 21 has a clamping plate 31, and the inner arc surface of the clamping plate 31 has a side anti-slip pad 33. Both the bottom anti-slip pad 32 and the side anti-slip pad 33 can be made of rubber or other anti-slip materials to ensure effective clamping and positioning. The adjustment mechanism includes an insertion slot 44 on the support plate 21, which inserts into the support plate 21 to adjust its height, adapting to brake pads of different thicknesses and providing better clamping and positioning for the sides. The side walls of the insertion slot 44 are symmetrically provided with threaded holes 43. The threaded holes 43 are fitted with fixing bolts 41 through threads. The fixing bolts 41 abut against the side wall of the support plate 21. By rotating the fixing bolts 41, the fixing bolts 41 can move within the threaded holes 43, which can tighten and loosen the support plate 21, making it easy to adjust and fix the position after adjustment. The fixing bolts 41 are also provided with washers 42 to ensure the tightening effect. The support plate 21 is symmetrically provided with guide posts 46 at one end near the vertical plate 15. The side wall of the insertion slot 44 near the vertical plate 15 is provided with guide grooves 45 that match the guide posts 46, which can guide and limit the movement when adjusting the height to prevent slippage.

[0018] Working principle: In use, the height of the clamping plate 31 is adjusted according to the thickness of the brake pad to be processed. The fixing bolt 41 is rotated counterclockwise to release the clamping plate 31, allowing it to slide within the insertion groove 44. The guide post 46 slides within the guide groove 45 to prevent slippage. The clamping plate 31 can then be adjusted to a suitable height. The fixing bolt 41 is then rotated clockwise to tighten the clamping plate 31 and prevent slippage. The brake pad to be processed is placed between the three sets of support plates 21. The electric push rod 13 in the slide groove 12 extends, causing the slider 14 to slide within the slide groove 12. The limiting block 17 is positioned within the limiting groove 1. 6. The sliding mechanism guides and limits movement to ensure stability. At this time, the bottom anti-slip pad 32 on the support plate 21 contacts the bottom of the brake shoe. As the movement continues, the side anti-slip pad 33 on the clamping plate 31 contacts the side of the brake shoe. The movement then exerts a squeezing force on the support plate 21, causing the rotating part 23 to rotate in the rotating groove 22. This allows the clamping plate 31 to better fit against the side of the brake shoe. The movement continues to complete the clamping and fixing, ensuring a stable and secure clamping, which facilitates subsequent production and processing. When it is necessary to remove the brake shoe, the electric push rod 13 retracts, moving the entire assembly back to its original position, thus releasing the clamping and fixing, making it easy to remove.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
