Description

Technical Field

[0001] This utility model relates to the field of brake processing technology, and more specifically to a quick clamp for processing automobile brakes. Background Technology

[0002] The automotive brake is a core component for safe driving. Its machining precision directly affects the braking performance and driving safety of the entire vehicle. With the rapid development of the automotive industry, the demand for brake parts is constantly increasing, which also puts forward higher requirements for its machining efficiency and quality. In particular, brake pads, if the machining does not meet the requirements, will affect the overall braking effect.

[0003] In the machining process of brake pads inside the brake, the fixture is a key piece of equipment that fixes the workpiece and positions it in the correct machining position. Its performance directly affects machining accuracy, production efficiency, and operational safety. However, current fixtures have the following problems:

[0004] Since the shape and size of brake pads are not fixed, when the workpiece fixing surface is uneven, the one-piece pressure plate has limited freedom and is prone to loose clamping, resulting in unstable clamping. When clamping irregular structures, the clamping process is cumbersome and wastes a lot of time in the preparation stage of processing. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick clamp for processing automobile brakes to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a quick clamp for processing automotive brakes, comprising a clamping table, a first clamping mechanism fixedly connected to one side of the top of the clamping table, a placement plate fixedly connected to the bottom of the side of the first clamping mechanism, a brake pad placed on the top of the placement plate, an adjustment mechanism movably connected to the interior of the clamping table away from the first clamping mechanism, and a second clamping mechanism fixedly connected to the top of the adjustment mechanism, the first clamping mechanism and the second clamping mechanism having the same structure; both the first clamping mechanism and the second clamping mechanism include a support block for fixed support, contact heads movably connected to the sides of the support blocks that are close to each other, sliding blocks fixedly connected to the sides of the contact heads that are far from each other, a limit rod fixedly connected to the side of the sliding block away from the contact head, a clearance hole for accommodating the limit rod being opened in the support block, a support spring being provided on the side of the limit rod, two rows of sliding blocks, a pressing plate being provided at the top and bottom of the sliding blocks, a connecting plate fixedly connected to the top of the pressing plate, a magnetic block fixedly connected inside the connecting plate, and an electromagnet being provided at the top of the magnetic block.

[0007] Furthermore, the bottom end of the placement plate is fixedly connected to the top end of the clamping platform, and the placement plate is located below the contact head inside the second clamping mechanism. The top ends of the first clamping mechanism and the second clamping mechanism are provided with clearance angles on their respective sides.

[0008] Furthermore, the electromagnet is fixedly connected to the inside of the support block, and the connecting plate and the magnetic block can move within the support block. There are three magnetic blocks and three electromagnets.

[0009] Furthermore, each of the sliding blocks in the upper row is provided with a pressing plate at its top end, and each of the sliding blocks in the lower row is provided with a pressing plate at its bottom end. Each of the sliding blocks is in contact with each other, and the sliding blocks are in contact with the pressing plates before and after they move.

[0010] Furthermore, the adjustment mechanism includes a first movable plate and a second movable plate that are fixedly connected to the bottom end of the second clamping mechanism. The first movable plate is internally threaded with a threaded rod, and an adjustment wheel is fixedly connected to the side of the threaded rod. The adjustment wheel is located outside the clamping table.

[0011] Furthermore, a support rod is movably connected inside the second movable plate, and a sliding groove is provided at the top of the clamping platform for the first movable plate and the second movable plate to move. The support rod is fixedly connected to the sliding groove inside the clamping platform.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. When the first clamping mechanism and the second clamping mechanism of this utility model come into contact with both sides of the brake pad, if the surface of the brake pad is irregular, the irregular surface will drive the contact head to move. When the contact head moves, it will drive the sliding block and the limiting rod to move and compress the support spring. At this time, after matching with the irregular brake pad, the electromagnet is energized and a magnetic repulsion force is generated between it and the magnetic block. The magnetic block drives the pressing plate to move through the connecting plate and presses the sliding block, thereby locking the position of the sliding block and the contact head, and quickly performing precise and firm clamping work on the irregular surface.

[0014] 2. When clamping, the adjusting wheel is rotated and the threaded rod is rotated. When the threaded rod rotates, the second clamping mechanism is moved through the first moving plate. The second clamping mechanism moves the brake pad and contacts the first clamping mechanism on the other side. At this time, the contact head will adapt to the irregular shape on both sides of the brake pad and compress the support spring. After the electromagnet is energized, the locking and clamping work can be performed quickly to realize the quick clamping and fixing of the brake pad. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 This utility model provides a quick clamp for processing automotive brakes, including a clamping table 1. A first clamping mechanism 2 is fixedly connected to one side of the top of the clamping table 1. A placement plate 3 is fixedly connected to the bottom of the side of the first clamping mechanism 2. A brake pad 4 is placed on the top of the placement plate 3. An adjustment mechanism 6 is movably connected to the inside of the clamping table 1 away from the first clamping mechanism 2. A second clamping mechanism 5 is fixedly connected to the top of the adjustment mechanism 6. The first clamping mechanism 2 and the second clamping mechanism 5 have the same structure. The bottom of the placement plate 3 is fixedly connected to the top of the clamping table 1, and the placement plate 3 is located below the contact head 503 inside the second clamping mechanism 5. The top of the sides of the first clamping mechanism 2 and the second clamping mechanism 5 that are close to each other are provided with a clearance angle.

[0023] In this embodiment, the placement plate 3 is located below the contact head 503 inside the second clamping mechanism 5. The placement plate 3 will not affect the clamping operation of the second clamping mechanism 5. The top of the first clamping mechanism 2 and the second clamping mechanism 5 are provided with a clearance angle to avoid the subsequent processing and facilitate the smooth progress of the processing work.

[0024] Reference Figure 2 , Figure 3 as well as Figure 4 Both the first clamping mechanism 2 and the second clamping mechanism 5 include support blocks 501 for fixed support. Contact heads 503 are movably connected to the sides of the support blocks 501 that are close to each other. Sliding blocks 504 are fixedly connected to the sides of the contact heads 503 that are far apart from each other. Limiting rods 509 are fixedly connected to the sides of the sliding blocks 504 that are far from the contact heads 503. A clearance hole 502 is provided in the support block 501 to accommodate the limiting rod 509. A support spring 510 is provided on the side of the limiting rod 509. The sliding blocks 504 are arranged in two rows. A pressing plate 505 is provided at both the top and bottom of the sliding blocks 504. A connecting plate 506 is fixedly connected to the top of the support block 501. An electromagnet 508 is fixedly connected inside the connecting plate 506. The electromagnet 508 is fixedly connected to the inside of the support block 501. The connecting plate 506 and the magnetic block 507 can move inside the support block 501. There are three magnetic blocks 507 and three electromagnets 508. The top of each of the upper row of sliding blocks 504 is provided with a pressing plate 505. The bottom of each of the lower row of sliding blocks 504 is provided with a pressing plate 505. Each sliding block 504 is in contact with each other. The sliding block 504 is in contact with the pressing plate 505 before and after moving.

[0025] In this embodiment, when the contact head 503 is in contact with the irregular shape of the brake pad 4, the contact head 503 can drive the sliding block 504 and the limiting rod 509 to move and compress the support spring 510. At this time, the contact head 503 will be in contact with the side of the brake pad 4. Therefore, when the electromagnet 508 and the magnetic block 507 generate magnetic repulsion, under the action of magnetic repulsion, the magnetic block 507 drives the pressing plate 505 to move towards the sliding block 504 through the connecting plate 506. The upper and lower sides of the two sliding blocks 504 are provided with pressing plates 505. The pressing plates 505 pressing each other fix the sliding blocks 504 more firmly. This application uses electromagnetic fixation, which has a faster response speed and improves the overall operating efficiency.

[0026] Reference Figure 5 The adjusting mechanism 6 includes a first moving plate 601 and a second moving plate 604 that are fixedly connected to the bottom end of the second clamping mechanism 5. The first moving plate 601 is internally threaded with a threaded rod 602, and an adjusting wheel 603 is fixedly connected to the side of the threaded rod 602. The adjusting wheel 603 is located on the outside of the clamping table 1. A support rod 605 is movably connected inside the second moving plate 604. The top of the clamping table 1 is provided with a sliding groove for the first moving plate 601 and the second moving plate 604 to move. The support rod 605 is fixedly connected to the sliding groove inside the clamping table 1.

[0027] In this embodiment, the adjusting wheel 603 rotates, causing the threaded rod 602 to rotate. When the threaded rod 602 rotates, the first moving plate 601 causes the second clamping mechanism 5 to move towards the first clamping mechanism 2. When the second clamping mechanism 5 moves, it causes the brake pad 4 to move. At this time, the brake pad 4 contacts the contact head 503 in the first clamping mechanism 2 and the second clamping mechanism 5 respectively. The contact head 503 contacts the irregular shape on the surface of the brake pad 4 and adapts to it. After adaptation, the first clamping mechanism 2 and the second clamping mechanism 5 perform fixed clamping, resulting in higher overall working efficiency.

[0028] The working principle of this utility model is as follows: When it is necessary to clamp the brake pad 4, the brake pad 4 is placed on the placement plate 3. At this time, the side of the brake pad 4 contacts the side of the first clamping mechanism 2. After contact, the adjusting wheel 603 is rotated. After the adjusting wheel 603 rotates, it drives the threaded rod 602 to rotate. When the threaded rod 602 rotates, the first moving plate 601 drives the second clamping mechanism 5 to move towards the first clamping mechanism 2. When the second clamping mechanism 5 moves, it drives the brake pad 4 to move. At this time, the brake pad 4 contacts the contact head 503 in the first clamping mechanism 2 and the second clamping mechanism 5 respectively. The contact head 503 contacts the irregular shape on the surface of the brake pad 4 and adapts to it. When adapting, the contact head 503 can drive the sliding block 504 and the limiting rod 509 to move and compress the support spring 510.

[0029] When the contact head 503 is adapted to the irregular surface of the brake pad 4, the adjusting wheel 603 stops rotating. At this time, the electromagnet 508 is energized. After the electromagnet 508 is energized, a magnetic repulsion force is generated between it and the magnetic block 507. Under the action of the magnetic repulsion force, the magnetic block 507 drives the pressing plate 505 to move towards the sliding block 504 through the connecting plate 506. The upper and lower sides of the two sliding blocks 504 are provided with pressing plates 505. The pressing plates 505 pressing against each other fix the sliding blocks 504. At this time, processing can be performed.

[0030] After processing, the adjusting wheel 603 is rotated in the opposite direction. At this time, the second clamping mechanism 5 moves away from the brake pad 4, thereby releasing the brake pad 4. When the brake pad 4 is released, the electromagnet 508 is de-energized. After the electromagnet 508 is de-energized, the magnetic repulsion between it and the magnetic block 507 disappears. At this time, the compressed support spring 510 causes the sliding block 504 to reset, which in turn causes the contact head 503 to reset, thereby performing the clamping work of the next brake pad 4.

[0031] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
