Description

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 adjust. Background Technology

[0002] A brake disc is typically a metal disc with a central mounting hole, which is fixed to the wheel and rotates with it. Some brake discs also have ventilation holes, ventilation slots, or special disc surface designs such as scribing and drilling. The brake disc blank is machined on a lathe, mainly turning the outer diameter, inner hole, and end face to leave a certain machining allowance for subsequent finishing. The mounting holes and ventilation slots of the brake disc are machined on a milling machine. For ventilated disc brake discs, ventilation holes or grooves need to be milled into the disc body to improve heat dissipation performance. The outer diameter, inner hole, and end face are precision machined to ensure dimensional accuracy and surface roughness. Grinding is then used to grind the friction surface of the brake disc to further improve surface flatness and smoothness, ensuring good contact between the brake disc and brake pads, reducing vibration and noise during braking. Through heat treatment processes such as quenching and tempering, the brake disc is heated to a high temperature of 850-900℃ and then rapidly cooled, followed by tempering at around 200-300℃ to improve the hardness, wear resistance, and heat resistance of the brake disc, enhancing its overall performance and extending its service life.

[0003] In the existing technology, during the partial processing of the brake disc, it is necessary to clamp and fix the brake disc to ensure that the brake disc is stable during processing and does not become skewed, thereby ensuring the processing quality and efficiency of the brake disc.

[0004] However, the existing clamping size adjustment is not flexible enough and it is difficult to adapt to brake discs of different sizes. When it is necessary to process brake discs of different sizes, it takes a long time to adjust the clamping, which affects the efficiency of brake disc processing. Utility Model Content

[0007] A clamping device for easy-to-adjust brake disc production includes a processing table. The top of the processing table has three limiting grooves. A spacer box is slidably connected inside the limiting grooves. A spacer mechanism is provided between the spacer box and the limiting grooves. An L-shaped pressing rod is rotatably connected inside the spacer box. A reset rod is rotatably connected to the top of the pressing rod. An upper pressure rod is provided on the top of the reset rod through an adjustment mechanism. A side pressure rod is fixedly connected to the side of the pressing rod.

[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] Reference Figure 1-5A clamping device for brake disc production that is easy to adjust includes a processing table 1. When the brake disc needs to be processed, the brake disc is placed on the processing table 1 and then fixed. After the brake disc is fixed, it is processed. After processing, the brake disc is released from the fixing, the brake disc is replaced, and then processing continues. The top of the processing table 1 has three limiting grooves 2, which can conveniently clamp and fix the brake disc from three directions, so that the brake disc can be processed stably. A spacer box 3 is slidably connected inside the limiting grooves 2. The bottom section of the spacer box 3 is... The spacer box 3 has a T-shaped cross-section, and the limiting groove 2 also has a T-shaped cross-section. During use, the spacer box 3 will not detach from the interior of the limiting groove 2. A spacer mechanism 4 is provided between the spacer box 3 and the limiting groove 2. When dealing with brake discs of different specifications, the spacer mechanism 4 is used to move and adjust the spacer box 3 within the limiting groove 2, so that the brake discs of different specifications can be easily clamped and fixed, ensuring the smooth processing of brake discs of different specifications. An L-shaped pressing rod 5 is rotatably connected inside the spacer box 3. When clamping the brake disc, the three pressing rods 5 are rotated first, and then... The brake disc is then placed between the three pressing rods 5 from top to bottom, causing the brake disc to press against the three pressing rods 5. This causes the pressing rods 5 to rotate due to the weight of the brake disc. A reset rod 6 is rotatably connected to the top of the pressing rod 5. In processing steps where using the reset rod 6 does not affect the brake disc machining, the reset rod 6 is rotated closer to the brake disc. After the brake disc descends, the reset rod 6 is driven to rotate by the pressing rods 5, causing the upper pressure rod 8 on the reset rod 6 to press and fix the top of the brake disc. The upper pressure rod 8 is located on the top of the reset rod 6 via an adjustment mechanism 7. When dealing with brake discs of different specifications, the upper pressure rod 8 can be adjusted via this mechanism. 7 allows for height adjustment of the upper pressure rod 8, facilitating the compression of brake discs of different specifications when the upper pressure rod 8 is needed, resulting in more stable compression and fixing of brake discs of different specifications. The side pressure rod 9 is fixedly connected to the side of the compression rod 5. When the compression rod 5 is rotated by the brake disc, the side pressure rod 9 clamps and fixes the surface of the brake disc, facilitating stable clamping and fixing of the brake disc and improving the stability during brake disc processing. When the brake disc needs to be replaced, simply rotate the compression rod 5, causing the end of the compression rod 5 located at the bottom of the brake disc to tilt up, lifting the brake disc for easy replacement.

[0024] Furthermore, the distance fixing mechanism 4 includes several distance fixing slots 401 formed inside the limiting slot 2. An extension rod 402 is fixedly connected to the side of the distance fixing box 3. A distance fixing rod 403 passes through the top of the extension rod 402. One end of the distance fixing rod 403 passes through the adjacent distance fixing slot 401. When it is necessary to change the position of the distance fixing box 3 to facilitate the fixing of brake discs of different specifications, the distance fixing rod 403 on the extension rod 402 can be pulled upward first, so that the distance fixing rod 403 can be disengaged from the distance fixing slot 401. Then, the position of the distance fixing box 3 is moved inside the limiting slot 2. The position of the distance fixing box 3 is determined according to the specifications of the brake disc. After the position of the distance fixing box 3 is determined, the distance fixing rod 403 is lowered, so that the distance fixing rod 403 enters the adjacent distance fixing slot 401. The position of the distance fixing box 3 is fixed again to facilitate the clamping and fixing of the brake disc.

[0025] Furthermore, the top of the spacer rod 403 is elastically connected to the top of the extension rod 402 via a compression spring 404. When the spacer rod 403 needs to be used to fix the position of the spacer box 3 by being locked in the spacer groove 401, the compression spring 404 can make the spacer rod 403 always have a downward force, so that the spacer rod 403 will not easily leave the spacer groove 401, making it convenient to fix the position of the spacer box 3.

[0026] Furthermore, the adjustment mechanism 7 includes several adjustment slots 701 formed on the surface of the upper pressure rod 8. The upper pressure rod 8 passes through the top of the reset rod 6, and a screw 702 is threadedly connected to the side of the reset rod 6. The screw 702 passes through the interior of the adjacent adjustment slots 701. When adjusting the height of the upper pressure rod 8, the screw 702 can be rotated to move away from the adjustment slot 701. Then, the upper pressure rod 8 can be moved up and down on the reset rod 6 to adjust its position. After adjusting the position, the screw 702 can be rotated again to allow one end of the screw 702 to enter the adjacent adjustment slot 701 to fix the position of the upper pressure rod 8 again. This facilitates the upper pressure rod 8 to press and fix brake discs of different specifications from above.

[0027] Furthermore, two receiving boxes 703 are fixedly connected to the surface of the compression rod 5. The interior of the two receiving boxes 703 is elastically connected to an anti-rotation plate 705 through a compression spring 704. The reset rod 6 is located between the two anti-rotation plates 705. When using and not using the reset rod 6, it is only necessary to rotate the reset rod 6 to different directions. During this process, the anti-rotation plate 705 needs to be pressed downward so that the reset rod 6 will not be obstructed when rotating. After rotating, the anti-rotation plate 705 is released. The anti-rotation plate 705 pops out through the compression spring 704 inside the receiving box 703 and fits against the side of the reset rod 6, thereby blocking the rotation of the reset rod 6.

[0028] Furthermore, anti-collision pads 10 are fixedly connected to one end of both the side pressure rod 9 and the upper pressure rod 8. When the brake disc is clamped and fixed by the side pressure rod 9 and the upper pressure rod 8, the anti-collision pads 10 can conveniently protect the brake disc and prevent damage to the brake disc during compression, thus affecting the quality of the brake disc.

[0029] In summary:

[0030] When processing the brake disc on the processing table 1, the spacer box 3 and the upper pressure rod 8 can be adjusted according to the specifications of the brake disc. The spacer rod 403 on the extension rod 402 is pulled upward, so that the spacer rod 403 disengages from the spacer groove 401. Then the spacer box 3 is moved, so that the pressing rod 5 moves accordingly. After the spacer box 3 finds the corresponding specification position inside the limit groove 2, the spacer rod 403 is released. The spacer rod 403 re-enters the adjacent spacer groove 401 by gravity and the elastic force of the compression spring 404, thus determining the position of the spacer box 3. Then, depending on whether the lower pressure rod is needed, the reset rod 6 is rotated. When the reset rod 6 rotates, the anti-rotation plate 705 is pressed downward, so that the rotation of the reset rod 6 is unobstructed. After the reset rod 6 finishes rotating, the anti-rotation plate 705 is released. The anti-rotation plate 705 rises through the compression spring 704 inside the receiving box 703, and then the reset rod 6 is clamped to prevent rotation. Then the screw 702 is rotated to make the screw... Rod 702 disengages from adjustment slot 701, then the upper pressure rod 8 moves up and down to properly position and restrict the brake disc. Screw 702 is then rotated back into the adjacent adjustment slot 701. After all adjustments are complete, the three pressing rods 5 are rotated, and the brake disc is placed from top to bottom. The brake disc, through gravity, drives the three pressing rods 5 to rotate, causing the side pressing rods 9 and upper pressure rod 8 on the pressing rods 5 to press and position the brake disc. The side pressing rods 9 and upper pressure rod 8 are protected by the anti-collision pad 10, ensuring the brake disc is clamped and fixed. The brake disc is then processed. After processing, rotating the pressing rods 5 lifts the brake disc, facilitating material replacement. This structure allows for convenient clamping and fixing of brake discs of different specifications during processing, improving versatility and ensuring stable processing, thus enhancing processing efficiency.
