Description

Technical Field

[0001] This utility model relates to the field of brake pad processing technology, specifically to an automotive brake pad positioning and processing device. Background Technology

[0002] Automotive brake pads, also known as brake discs, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automotive brake pads are generally composed of steel plates, adhesive heat insulation layers, and friction blocks. The steel plates are coated to prevent rust. The coating process uses an SMT-4 oven temperature tracker to detect the temperature distribution during the coating process to ensure quality. The most common type of automotive brake pad is the drum brake pad, which is a sheet-like product with a curved structure.

[0003] During the manufacturing process of drum brake pads, a specific positioning device is required to fix them. However, some existing drum brake pad positioning and processing devices can only position and fix drum brake pads of a fixed size, which is not convenient for positioning and fixing drum brake pads of different sizes, greatly reducing the practicality and applicability of the device. Utility Model Content

[0004] To address the problem that existing drum brake pad positioning and processing devices can only position and fix drum brake pads of fixed sizes, resulting in low practicality and applicability, the purpose of this utility model is to provide a new type of automotive brake pad positioning and processing device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automotive brake pad positioning and processing device, including a worktable, on which a clamping assembly and a limiting assembly are installed. The clamping assembly includes two fixed frames distributed in a mirror image, and the two fixed frames are respectively fixedly installed at both ends of the upper surface of the worktable. Sliding blocks are slidably installed in both fixed frames, and first threaded rods are rotatably installed in both fixed frames. The first threaded rods are threadedly inserted into the corresponding sliding blocks. Clamping blocks are slidably installed on the side of the two sliding blocks that are close to each other. The limiting assembly includes two limiting plates symmetrically distributed. A first sliding groove is opened in the middle of the upper surface of the worktable, and the bottom end of the limiting plate is slidably locked in the first sliding groove. A bidirectional lead screw is rotatably installed in the first sliding groove, and the bidirectional lead screw is threadedly inserted into the bottom end of the two limiting plates. A third knob is fixedly installed at one end of the bidirectional lead screw.

[0006] Preferably, a second sliding groove is provided on the side of the two sliding blocks that are close to each other, and the clamping block can slide and rise along the corresponding second sliding groove. A second threaded rod is rotatably installed in each of the two second sliding grooves, and the second threaded rod is threaded into the corresponding clamping block. A first knob is fixedly installed at one end of each of the two first threaded rods, and a second knob is fixedly installed at the top end of each of the two second threaded rods. Limiting blocks are fixedly installed on both sides of the side of the two sliding blocks that are far apart from each other. Limiting grooves are provided on both sides inside the two fixed frames, and the limiting blocks on the sliding blocks are slidably locked in the corresponding limiting grooves.

[0007] Preferably, accordion covers are fixedly installed at the openings of the two second slides and the first slide, and a scale is fixedly installed on one side of the worktable.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. In this utility model, by setting a limiting component, the drum brake pads of different sizes can be limited by the limiting component to prevent lateral displacement of the drum brake pads during processing.

[0010] 2. In this utility model, by setting a clamping component, the drum brake pads of different sizes can be positioned, clamped and fixed by the clamping component to prevent the drum brake pads from shifting laterally during processing and to prevent the drum brake pads from shaking up and down during processing.

[0018] 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.

[0019] Example: Figure 1-5As shown, this utility model provides an automotive brake pad positioning and processing device, including a worktable 1. A clamping assembly 2 and a limiting assembly 3 are installed on the worktable 1. The clamping assembly 2 includes two mirror-distributed fixed frames 201, which are respectively fixedly installed at both ends of the upper surface of the worktable 1. Sliding blocks 202 are slidably installed in both fixed frames 201, and first threaded rods 205 are rotatably installed in both fixed frames 201, with the first threaded rods 205 threaded into the corresponding sliding blocks 202. Clamping blocks 203 are slidably installed on the side of the two sliding blocks 202 that are close to each other. The limiting assembly 3 includes two symmetrically distributed limiting plates 301. A first sliding groove 101 is formed in the middle of the upper surface of the worktable 1, and the bottom end of the limiting plate 301 is slidably engaged in the first sliding groove 101. A bidirectional lead screw 303 is rotatably installed in the first sliding groove 101, and the bidirectional lead screw 303 is threaded into the bottom ends of the two limiting plates 301. A third knob 302 is fixedly installed at one end of the lead screw 303. First, according to the width of the drum brake pad 6, the third knob 302 drives the double-acting lead screw 303 to rotate. The double-acting lead screw 303 drives the two limiting plates 301 to slide along the first slide groove 101, moving away from or closer to each other. The drum brake pad 6 is placed on the worktable 1, so that the drum brake pad 6 is located between the two limiting plates 301. The limiting plates 301 limit the drum brake pad 6 to prevent longitudinal displacement during processing. Then, according to the length of the drum brake pad 6, the first threaded rod 205 drives the sliding block 202 to slide within the fixed frame 201, so that the two sliding blocks 202 move closer to each other to clamp and fix the drum brake pad 6 in the center, preventing lateral displacement during processing. Then, the clamping block 203 slides down to clamp and fix the end of the drum brake pad 6, preventing the drum brake pad 6 from shaking up and down during processing.

[0020] Each of the two sliding blocks 202 has a second sliding groove 2021 on one side that is close to each other, and the clamping block 203 can slide and rise along the corresponding second sliding groove 2021. A second threaded rod 206 is rotatably installed in each of the two second sliding grooves 2021, and the second threaded rod 206 is threaded into the corresponding clamping block 203. A first knob 204 is fixedly installed at one end of each of the two first threaded rods 205, and a second knob 207 is fixedly installed at the top of each of the two second threaded rods 206. The first knob 204 and the second knob 207 can be used to drive the first threaded rod 205 and the second threaded rod 206 to rotate, and the second threaded rod 206 can be used to drive the clamping block 203 to slide and rise along the second sliding groove 2021.

[0021] Limiting blocks 2022 are fixedly installed on both sides of the two sliding blocks 202 at their opposite ends. Limiting grooves 2011 are opened on both sides of the interior of the two fixed frames 201. The limiting blocks 2022 on the sliding blocks 202 are slidably locked in the corresponding limiting grooves 2011. The sliding blocks 202 can slide along the limiting grooves 2011 in the fixed frames 201 through the limiting blocks 2022. The limiting grooves 2011 can limit the limiting blocks 2022 to prevent the sliding blocks 202 from sliding out of the fixed frames 201.

[0022] A bellows cover 4 is fixedly installed at the openings of the two second slides 2021 and the first slide 101. The bellows cover 4 can prevent the waste generated during processing from entering the second slides 2021 and the first slide 101 and affecting the rotation of the second threaded rod 206 and the double-acting screw 303. A scale 5 is fixedly installed on one side of the worktable 1. The scale 5 makes it easy to observe the movement distance of the sliding block 202 and to center and clamp the drum brake pad 6.

[0023] Working Principle: In use, this utility model first rotates the double-acting screw 303 by using the third knob 302 to rotate the double-acting screw 303 according to the width of the drum brake pad 6. The double-acting screw 303 drives the two limiting plates 301 to slide along the first slide groove 101, moving them away from or closer to each other. Then, the drum brake pad 6 is placed on the worktable 1, so that the drum brake pad 6 is positioned between the two limiting plates 301. The limiting plates 301 limit the drum brake pad 6 to prevent longitudinal displacement during processing. Then, according to the length of the drum brake pad 6, the double-acting screw 303 rotates the first slide groove 101 to rotate the second slide groove 101. The first knob 204 drives the first threaded rod 205 to rotate, and the first threaded rod 205 drives the sliding block 202 to slide within the fixed frame 201, so that the two sliding blocks 202 move closer to each other to clamp and fix the drum brake pad 6 in the center, preventing the drum brake pad 6 from shifting laterally during processing. Then, the second knob 207 drives the second threaded rod 206 to rotate, and the second threaded rod 206 drives the clamping block 203 to slide down, clamping and fixing the end of the drum brake pad 6, which can prevent the drum brake pad 6 from shaking up and down during processing.

[0024] This device can be fitted onto the appropriate position on an automotive brake pad processing device. After the drum brake pads are positioned and clamped in place using this device, they can be processed accordingly using the automotive brake pad processing device.
