Description

Technical Field

[0001] This utility model relates to the field of brake disc drilling technology, and in particular to a drilling device for easy positioning in brake disc production. 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. There are two main structural types: solid and ventilated. Ventilated brake discs have numerous circular ventilation holes drilled into their surface, or ventilation grooves or pre-fabricated rectangular ventilation holes cut into their end faces. When the braking system is activated, the brake piston pump inside the caliper uses hydraulic oil to push the inner brake pads towards the brake disc. Simultaneously, the reaction force pulls the caliper, causing the outer brake pads to move inward. Both inner and outer brake pads press tightly against the brake disc, generating braking force through friction to decelerate or stop the brakes. Drilling the brake disc is a common design optimization method. The surface of a drilled brake disc has many small holes, increasing the contact area between the brake disc and the air. During braking, the brake disc generates a large amount of heat due to friction. Air can quickly carry away this heat through these small holes, effectively reducing the brake disc temperature and minimizing brake fade. During braking, brake pads produce debris due to friction. If this debris accumulates on the brake disc surface, it can affect braking performance and may cause abnormal braking noise. When a perforated brake disc rotates, the small holes can fling out these debris, keeping the surface of the brake disc clean, making the friction between the brake pads and the brake disc more even, reducing abnormal noise, and extending the service life of the brake pads and brake disc.

[0003] In the existing technology, when producing brake discs, the brake disc can be placed on a processing table, then positioned, and then a drilling machine is started to drill holes in the brake disc. After drilling is completed, the brake disc is replaced and the drilling process continues.

[0004] However, existing brake disc drilling devices are inconvenient to adjust when positioning brake discs of different sizes, making it difficult for the positioning device to quickly adapt to different brake disc sizes, affecting drilling efficiency and resulting in low production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for easy positioning in brake disc production, which solves the problem of reduced drilling efficiency caused by the inability of the existing technology to adapt to the positioning of brake discs of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drilling device for easy positioning in brake disc production includes a processing table and a drilling machine. The top of the processing table has a sliding groove, and an adjusting block is slidably connected inside the sliding groove. An extension column is fixedly connected to the top of the adjusting block. A fixing mechanism is provided between the extension column and the processing table. A disc is fixedly connected to the top of the extension column. The top of the disc has three limiting grooves, and a limiting rod is provided inside the limiting grooves through the adjusting mechanism.

[0008] Preferably, the fixing mechanism includes a pull rod that is rotatably fixed to the surface of the extension column, and two anti-movement grooves are provided on the top of the processing table. An inverted U-shaped anti-movement rod is inserted through the top of the pull rod, and one end of the anti-movement rod is inserted into the interior of the adjacent anti-movement groove.

[0009] Preferably, the top of the anti-movement rod and the pull rod are elastically connected by a compression spring.

[0010] Preferably, the adjustment mechanism includes two movable slots formed inside the limiting slot, and a movable rod is fixedly connected to the surface of the limiting rod, with both sides of the movable rod located inside the adjacent movable slot.

[0011] Preferably, the top of the moving rod is threaded with a screw, and the bottom of the limiting groove is provided with several positioning grooves, with the screw located inside the adjacent positioning grooves.

[0012] Preferably, the sliding groove has two anti-detachment strips fixedly connected inside, and the extension column passes between the two anti-detachment strips.

[0013] This utility model has the following beneficial effects:

[0014] When drilling brake discs, the brake disc can be easily placed onto the disc and positioned by three limit rods. Then, it is fed into the drilling machine through the sliding groove for drilling. When drilling brake discs of different specifications, the limit rods can be adjusted to easily position and fix the brake discs of different specifications, thus making the positioning of brake discs of different specifications convenient and not affecting the efficiency of brake disc production.

[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 drilling device for easy positioning in brake disc production includes a processing table 1 and a drilling machine 2. The processing table 1 is a worktable for supporting the brake disc, facilitating the processing of the brake disc. The drilling machine 2 is a mature existing technology, using a motor to drive rotating components such as drill bits or drilling pins, and using the cutting edge of the drill bit to cut the brake disc material, thereby forming holes in the brake disc. A sliding groove 3 is provided on the top of the processing table 1, which is a groove on the processing table 1 to facilitate loading and unloading. The sliding groove 3 facilitates the feeding and unloading of the brake disc under the drilling machine 2, thereby improving drilling efficiency. An adjusting block 4 is slidably connected inside the sliding groove 3. The adjusting block 4 slides within the sliding groove 3 to move the brake disc in and out of the drilling machine 2. An extension column 5 is fixedly connected to the top of the adjusting block 4. The extension column 5 allows for a certain space between the disc 7 and the processing table 1, facilitating the driving and restraint of the adjusting block 4. A fixing mechanism 6 is provided between the extension column 5 and the processing table 1. When drilling is required, a fixing mechanism 6 is needed. The position of the extension column 5 is fixed by the fixing mechanism 6 to prevent the adjusting block 4 from sliding during processing, which could cause misalignment of the drilling position and affect the drilling effect of the brake disc. This ensures the normal progress of the drilling process. After the drilling is completed, the fixing mechanism 6 is opened to replace the brake disc. After replacement, the fixing mechanism is re-fixed to continue drilling. A disc 7 is fixedly connected to the top of the extension column 5. The disc 7 is a structure for placing the brake disc. Before feeding, the brake disc is placed on the disc 7 and then pushed under the drilling machine 2 for drilling. The top of the disc 7 has three limiting grooves. 8. The limiting groove 8 is equipped with limiting rods 10 through the adjustment mechanism 9. When it is necessary to restrict the brake disc on the disc 7, the limiting rods 10 can be moved inside the limiting groove 8 through the adjustment mechanism 9. By changing the position of the three limiting rods 10, the brake disc is clamped on the disc 7, thereby fixing the position of the brake disc on the disc 7. Then it is sent to the bottom of the drilling machine 2 for drilling. After drilling is completed, the brake disc is removed and replaced with a new brake disc. When replacing the same specification, the limiting rods 10 do not need to be adjusted. When replacing different specifications, the limiting rods 10 need to be adjusted to meet the requirements of the brake disc.

[0024] Furthermore, the fixing mechanism 6 includes a pull rod 601 rotatably fixed to the surface of the extension column 5. The top of the processing table 1 has two anti-movement grooves 602. The top of the pull rod 601 is provided with an inverted U-shaped anti-movement rod 603. One end of the anti-movement rod 603 passes through the interior of the adjacent anti-movement groove 602. When it is necessary to fix the position of the adjusting block 4 to facilitate the determination of the position of the brake disc, the adjusting block 4 can be moved inside the sliding groove 3 by the pull rod 601, so that the adjusting block 4 drives the brake disc to change position. Then, when it moves to the anti-movement groove 602, the two ends of the anti-movement rod 603 are respectively inserted into the interior of the adjacent anti-movement groove 602, so that the anti-movement rod 603 is restricted and fixed, so that the pull rod 601 is also restricted and fixed on the processing table 1, so that the brake disc on the disc 7 is fixed below the drilling machine 2. Then the drilling machine 2 is started to drill holes in the brake disc.

[0025] Preferably, the top of the anti-moving rod 603 and the pull rod 601 are elastically connected by a compression spring 604. During the drilling process, the compression spring 604 can easily exert a downward force on the anti-moving rod 603, thereby ensuring that the pull rod 601 can be stably restricted and fixed, ensuring the stability of the brake disc during the processing, and preventing the anti-moving rod 603 from dislodging from the anti-moving groove 602 and causing the brake disc to misalign.

[0026] Preferably, the adjustment mechanism 9 includes two movable slots 901 formed inside the limiting slot 8, and a movable rod 902 is fixedly connected to the surface of the limiting rod 10. Both sides of the movable rod 902 are located inside the adjacent movable slots 901. When the movable slots 901 are moved, when the brake disc is placed on the disc 7, the limiting rod 10 can be pushed by the movable rod 902, so that the positions of the three limiting rods 10 are adjusted to clamp and fix the brake disc.

[0027] Preferably, the top of the moving rod 902 is threadedly connected to a screw 903, and the bottom of the limiting groove 8 is provided with several positioning grooves 904. The screw 903 is located inside the adjacent positioning grooves 904. When the moving rod 902 pushes the limiting rod 10 to clamp and fix the brake disc, the positioning grooves 904 can be used to determine the fixing position of the brake disc of different specifications. After the positions of the three limiting rods 10 are adjusted, the screw 903 is rotated so that the screw 903 enters the positioning groove 904 of the corresponding specification brake disc, so that the three limiting rods 10 fix the position of the brake disc and ensure the stability of the brake disc during drilling.

[0028] Preferably, two anti-detachment strips 11 are fixedly connected inside the sliding groove 3, and the extension column 5 passes between the two anti-detachment strips 11. When the adjusting block 4 moves inside the sliding groove 3, it can be restricted by the anti-detachment strips 11 so that the adjusting block 4 will not detach from the sliding groove 3. Furthermore, the anti-detachment strips 11 are not attached to the two ends of the sliding groove 3, so the adjusting block 4 can be removed from the sliding groove 3 at the end of the sliding groove 3.

[0029] In summary:

[0030] When drilling holes in the brake disc on the machining table 1, the brake disc is first placed on the disc 7. Then, the screw 903 is rotated to disengage from the positioning groove 904. Next, the moving rod 902 pushes the limiting rod 10 to move inside the limiting groove 8. Both sides of the moving rod 902 are inside the adjacent moving grooves 901, ensuring that the limiting rod 10 does not disengage from the limiting groove 8. Afterward, when the moving rod 902 pushes the limiting rod 10 to the position corresponding to the brake disc size, the screw 903 is rotated again, allowing it to enter the adjacent positioning groove 904, fixing the position of the moving rod 902. This fixes the position of the limiting rod 10, thus securing the brake disc to the disc 7. Finally, the pulling rod 601, via the extension column 5, moves the adjusting block 4 inside the sliding groove 3. The sliding groove 3 remains in place during this movement. Furthermore, the adjusting block 4 can be removed from the sliding groove 3 at the end of the sliding groove 3. When the pulling rod 601 moves the brake disc to the bottom of the drilling machine 2, the anti-movement rod 603 can enter the anti-movement groove 602 downwards by the elastic force of the compression spring 604, thus fixing the position of the pulling rod 601 and the position of the brake disc. This makes it convenient for the drilling machine 2 to drill the brake disc. The U-shaped anti-movement rod 603 prevents the pulling rod 601 from tilting, ensuring the stability of the brake disc position and facilitating drilling. With the above structure, when drilling the brake disc, the position of the limiting rod 10 can be adjusted to easily position brake discs of different specifications, facilitating brake disc processing and maintaining stability during the processing, improving the efficiency of brake disc processing, and making it convenient to process brake discs of different specifications.
