Abstract
Description
A clamping device for easy-to-handle brake disc manufacturing Technical Field
[0001] This utility model relates to the field of brake disc production clamping technology, and in particular to a clamping device for brake disc production that is easy to handle. Background Technology
[0002] A brake disc is typically a metal disc with a central mounting hole. Its surface undergoes special treatment to improve friction and wear resistance. Its structure is mainly divided into two types: solid and ventilated. Ventilated brake discs have many circular ventilation holes drilled into the disc surface, or ventilation grooves or pre-fabricated rectangular ventilation holes cut into the end face of the disc. When the braking system is activated, the brake piston pump inside the brake caliper uses hydraulic oil to push the inner brake pads towards the brake disc. Simultaneously, the reaction force pulls the brake caliper, causing the outer brake pads to move inward as well. The inner and outer brake pads simultaneously press against the brake disc, generating braking force through friction to decelerate or stop the vehicle. Clamping is a crucial step in the brake disc production process. It refers to using fixtures to fix the brake disc blank on the machine tool during machining to ensure machining accuracy and stability. During clamping, appropriate protective measures should be taken at the contact points between the fixture and the brake disc to prevent scratches or indentations on the brake disc surface. Rubber pads or nylon clamping blocks can be installed to provide sufficient friction and protect the brake disc surface. Cast iron brake discs are the most common type, with good wear resistance and heat resistance, low cost and simple manufacturing process, but heavy weight and relatively poor thermal conductivity. They are suitable for various common vehicle models.
[0003] In the existing technology, when producing brake discs, the brake discs need to be clamped and fixed on the processing table first, and then the machine is started to process the brake discs. After processing is completed, the clamping and fixing of the brake discs is removed, and a new brake disc is installed to continue processing.
[0004] However, existing brake discs are placed on the processing table during processing. After processing is completed and the clamping mechanism is opened, it is inconvenient to pick up the brake disc from the processing table, which wastes time on replacing the brake disc and affects the efficiency of brake disc production and processing. Summary of the Invention
[0005] The purpose of this invention is to provide a clamping device for brake disc production that is easy to handle, solving the problem in the prior art where it is inconvenient to pick up the brake disc after processing, which affects the efficiency of replacement.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A clamping device for easy-to-handle brake disc production includes a processing table. The top of the processing table has a cross-shaped clamping groove. Four L-shaped clamping rods are rotatably connected inside the clamping groove. The surface of the clamping rods is provided with a pressing rod through an adjustment mechanism. The surface of the pressing rods is fixedly connected with a clamping column. A pop-out block is elastically connected to the center of the clamping groove through an output spring. A limiting mechanism is provided between the pop-out block and the processing table.
[0008] Preferably, the adjustment mechanism includes several adjustment slots formed on the surface of the extrusion rod, a cross-shaped lifting rod passing through the surface of the clamping rod, the top of the lifting rod passing through the interior of an adjacent adjustment slot, one end of the extrusion rod passing through the side of the clamping rod, and the bottom of the clamping column being in contact with the surface of the clamping rod.
[0009] Preferably, the surface of the lifting rod is elastically connected to the surface of the clamping rod via a return spring.
[0010] Preferably, the limiting mechanism includes four limiting blocks fixedly connected to the surface of the ejector block, and an extension rod fixedly connected to the surface of the clamping rod, with one end of the extension rod abutting against the top of the adjacent limiting block.
[0011] Preferably, the top of the processing table is provided with a quadrilateral limiting groove, and a quadrilateral anti-rotation ring is slidably connected inside the limiting groove, with the surface of the anti-rotation ring fitting against the surface of the clamping rod.
[0012] Preferably, the bottom of the anti-rotation ring is elastically connected to the inner side of the limiting groove by several compression springs, and several force-bearing plates are fixedly connected to the surface of the anti-rotation ring.
[0013] This utility model has the following beneficial effects:
[0014] During the processing of the brake disc, the position of the brake disc is clamped and fixed by the clamping pins. After the brake disc is processed, the restriction on the four clamping rods is released, so that the brake disc can be lifted by the spring force of the output spring and made easy to remove the brake disc from the processing table for removal and replacement.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] Referring to Figures 1-5, a clamping device for easy-to-handle brake disc production includes a processing table 1. The processing table 1 is the location for processing brake discs, facilitating the constraint and processing of the brake discs and ensuring stable processing. A cross-shaped clamping groove 2 is provided on the top of the processing table 1. Four L-shaped clamping rods 3 are rotatably connected inside the clamping groove 2. When processing the brake disc, it is placed on the processing table 1. The brake disc then presses against one end of the clamping rod 3, causing the clamping rod 3 to rotate inside the clamping groove 2. This causes the other end of the clamping rod 3 to rotate closer to the brake disc, thereby clamping and fixing the brake disc through the four clamping rods 3, ensuring normal production processing. The surface of the clamping rods 3 is provided with pressing rods 5 via an adjustment mechanism 4. When clamping and fixing brake discs of different specifications, the position of the pressing rods 5 can be adjusted through the adjustment mechanism 4, thereby facilitating the clamping of the four pressing rods 5. The machine tool is designed to clamp and fix brake discs of different specifications, facilitating the production and processing of brake discs of various sizes and meeting the production and processing requirements of brake discs. A clamping column 6 is fixedly connected to the surface of the extrusion rod 5. When the extrusion rod 5 restricts the brake disc, the clamping column 6 can better clamp and fix the brake disc, and can adapt to clamping and fixing brake discs of different thicknesses. This prevents the extrusion rod 5 from detaching from the brake disc due to height issues, thus preventing it from being unable to clamp and fix the brake disc. A pop-out block 8 is elastically connected to the center of the clamping groove 2 via a force spring 7. When the brake disc needs to be removed, the force spring 7 can easily push the pop-out block 8 upwards, allowing the brake disc to easily leave the processing table 1 and be easily picked up and moved. A limiting mechanism 9 is provided between the pop-out block 8 and the processing table 1. During normal processing, the limiting mechanism 9 can easily restrict the pop-out block 8, ensuring that the pop-out block 8 does not affect the normal processing of the brake disc.
[0024] Furthermore, the adjustment mechanism 4 includes several adjustment slots 401 formed on the surface of the extrusion rod 5. A cross-shaped lifting rod 402 passes through the surface of the clamping rod 3. The top of the lifting rod 402 passes through the interior of the adjacent adjustment slots 401. One end of the extrusion rod 5 passes through the side of the clamping rod 3. The bottom of the clamping column 6 is in contact with the surface of the clamping rod 3. When processing brake discs of different specifications, the position of the extrusion rod 5 needs to be adjusted so that the clamping column 6 can fit with brake discs of different specifications, thereby better clamping and fixing brake discs of different specifications. In this process, the lifting rod 402 needs to be pulled down first to disengage from the adjustment slot 401. Then, the extrusion rod 5 is moved to change the position of the clamping column 6. After that, the lifting rod 402 is reset and re-inserted into the adjustment slot 401 to fix the extrusion rod 5, so that the position of the extrusion rod 5 is fixed again and adapted to the new brake disc.
[0025] Furthermore, the surface of the lifting rod 402 is elastically connected to the surface of the clamping rod 3 via a return spring 403. When the lifting rod 402 is inserted into the adjustment slot 401 to fix the position of the pressing rod 5, the return spring 403 can give the lifting rod 402 an upward force. This allows the lifting rod 402 to move upward and re-insert into the adjacent adjustment slot 401 after it is disengaged from the adjustment slot 401, thus ensuring the adjustment and fixation of the position of the pressing rod 5.
[0026] Furthermore, the limiting mechanism 9 includes four limiting blocks 901 fixedly connected to the surface of the ejector block 8. An extension rod 902 is fixedly connected to the surface of the clamping rod 3. One end of the extension rod 902 is in contact with the top of the adjacent limiting block 901. During processing, the clamping rod 3 is driven to rotate by the brake disc. At this time, the extension rod 902 on the clamping rod 3 will squeeze the adjacent limiting block 901, causing the limiting block 901 to move downward, thereby driving the ejector block 8 to move downward, so that the ejector block 8 will not affect the processing of the brake disc. After processing, the clamping rod 3 is unrestricted. At this time, the elasticity of the output spring 7 causes the ejector block 8 to push the brake disc upward, thereby making it easy for the brake disc to be removed from the processing table 1 and improving the efficiency of material change.
[0027] Furthermore, the top of the processing table 1 is provided with a quadrilateral limiting groove 903. A quadrilateral anti-rotation ring 904 is slidably connected inside the limiting groove 903. The surface of the anti-rotation ring 904 is in contact with the surface of the clamping rod 3. After the brake disc is placed above the ejector block 8, the anti-rotation ring 904 is lifted upward, thereby causing the anti-rotation ring 904 to drive the four clamping rods 3 to rotate until the four clamping rods 3 are restricted, so that the four clamping rods 3 are restricted from rotating. At this time, the four clamping rods 3 can stably clamp and fix the brake disc. After processing is completed, pressing the anti-rotation ring 904 downward can release the restriction on the clamping rods 3, allowing the clamping rods 3 to rotate and the ejector block 8 to move upward.
[0028] Furthermore, the bottom of the anti-rotation ring 904 is elastically connected to the inner side of the limiting groove 903 through several compression springs 905. Several force plates 906 are fixedly connected to the surface of the anti-rotation ring 904. The compression springs 905 give the anti-rotation ring 904 an upward force, which can ensure that the anti-rotation ring 904 will not easily disengage when restricting the four clamping rods 3, causing the brake disc to be ejected by the ejector block 8, thus ensuring the stability during processing. The force plates 906 can easily apply force to the anti-rotation ring 904 when it is necessary to release the restriction, so that the anti-rotation ring 904 can easily move downward to release the restriction on the four clamping rods 3.
[0029] In summary:
[0030] During brake disc processing, the brake disc can be easily placed onto the processing table 1. The brake disc will press one end of the clamping rod 3, causing the clamping rod 3 to rotate. Then, the lifting rod 402 is pulled down, causing the lifting rod 402 to disengage from the adjusting groove 401. Next, the pressing rod 5 drives the clamping column 6 to adjust its position, so that the clamping column 6 can clamp and fix the brake disc. Then, the lifting rod 402 is released, and the top of the lifting rod 402 re-enters the adjacent adjusting groove 401 by the elastic force of the return spring 403, thus fixing the position of the pressing rod 5. Then, the anti-rotation ring 904 inside the limiting groove 903 is lifted upward. The anti-rotation ring 904 drives the four clamping rods 3 to rotate, thus limiting the four clamping rods 3. 4. The spring force of the compression spring 905 prevents the brake disc from detaching from the clamping rod 3. The ejector block 8 is restricted by the compression of the limiting block 901 by the four extension rods 902, which will not interfere with the processing of the brake disc. Then the machine is started to process the brake disc. After the brake disc is processed, the force plate 906 is applied to make the anti-rotation 904 enter the limiting groove 903. Then the ejector block 8 is squeezed upward by the spring force of the output spring 7, pushing the brake disc out of the processing table 1. Then the brake disc is removed and replaced to continue processing the next brake disc. With the above structure, when the brake disc needs to be processed, the clamping device is used to fix the position of the brake disc for easy processing. After processing, the brake disc can be easily removed and replaced with a new brake disc to continue processing.
