Description

Technical Field

[0001] The present invention relates to the technical field of drilling processing equipment, in particular to drilling processing equipment used in the production of automobile brake discs. Background Art

[0002] Drilling equipment used in brake disc production is primarily used to precisely create ventilation and mounting holes on brake discs to ensure heat dissipation and installation accuracy. This type of equipment typically features a highly rigid design to handle the machining of hard materials such as cast iron and composite materials. Equipped with a multi-axis CNC system for automated drilling, it can efficiently and simultaneously process multiple holes. Core components include a high-precision spindle unit, a servo drive system, and a rigid drill chuck, along with a coolant system to minimize drill wear. Advanced models integrate vision positioning or laser detection for real-time correction of hole position deviations, ensuring diameter tolerances within ±0.02mm. Some production lines utilize robotic loading and unmanned systems for unmanned production, achieving cycle times of 15-20 seconds per piece. The equipment must also include tool breakage detection and tool life management, using vibration sensors to prevent machining errors, and a chip collector to handle metal debris generated during drilling to meet environmental standards. Modern drilling equipment leverages the Industrial Internet to enable cloud-based optimization of machining parameters, significantly improving brake disc drilling quality and production efficiency.

[0003] When drilling holes in automobile brake discs, it is actually necessary to drill holes in brake discs of different sizes. However, each time a brake disc of different sizes is fixed, the inner diameter and outer diameter of the brake disc are different, and different clamps need to be used or the size of the clamps need to be adjusted repeatedly, which affects the drilling efficiency of the brake disc. In addition, when the existing drilling equipment initially fixes the brake disc, most of the time it only fixes the outer side of the brake disc with a clamp. When the brake disc is drilled, it will be subjected to vertical vibration force, and the vertical direction of the brake disc is not synchronously fixed. When the brake disc is drilled, it is easy to cause relatively large wear between the side and the clamp, thereby affecting the subsequent processing of the brake disc. Summary of the Invention

[0016] The drilling equipment for automobile brake disc production of the present invention has at least the following beneficial effects:

[0017] 1. The present invention utilizes the rotation of turntable 1, which pushes a set of positioning blocks within the chute to slide outward or inward along the chute via arcuate groove 1, thereby adapting to the outer and inner diameters of the brake disc. As turntable 2 follows the turntable downward, a second abutment block fixed to its inner side slides within the second abutment groove, ensuring its stable rotation. Turntable 2 rotates coaxially with the turntable, but features an arcuate groove 2 on its surface. The round block at the bottom of the positioning block, near the center of the connecting disc, fits into the arcuate groove 2. As turntable 2 rotates, the arcuate groove 2 pushes these positioning blocks along the chute, adapting to the inner diameter of the brake disc. This allows for simultaneous multi-point positioning of the inner and outer diameters of the brake disc, improving clamping stability.

[0018] 2. When the positioning block of the present invention approaches and contacts the brake disc of the automobile, the positioning block will first drive the trigger plate to contact the edge of the brake disc, so that the trigger plate rotates under the resistance force to drive the hinged plate to push the insertion rod to insert into the inner side of the positioning block, so that the insertion rod contacts the inclined surface of the L-shaped rod, and then forces the L-shaped rod to shrink to both sides, so that the L-shaped rod drives the limit rod to be pulled out of the limit hole. Then, the spring 2, which is initially tightened, will instantly pull the square rod downward, so that the square rod pulls the locking block to press the edge of the brake disc to prevent it from loosening during the drilling process.

[0019] 3. This invention releases the pressure plate from the push column, triggering the spring to reset. This resets the connecting disc and the positioning block, which then returns to its original position. Simultaneously, the trigger plate, activated by the torsion spring, resets, the insertion rod retracts, and the limiting rod disengages from the limiting hole in the square rod, allowing the completed brake disc to be removed. Throughout this process, the positioning and linkage components work together to ensure the brake disc remains stable during drilling, improving machining accuracy and efficiency.

The bottom surface of the positioning block 24 is fixedly connected with the round block 25, and the inner side of the connecting disk 22 is rotatably connected with the turntable 26. The top surface of the turntable 26 is fixedly connected with the anti-slip ring 27.

The turntable 212 rotates coaxially with the turntable 1 26, but an arc groove 213 is provided on the surface of the turntable 212. The round block 25 at the bottom of the positioning block 24 near the center of the connecting disk 22 is inserted into the arc groove 213. When the turntable 212 rotates, the arc groove 213 pushes these positioning blocks 24 to move along the slide groove 23, thereby adapting to the inner diameter size of the brake disc. Therefore, the inner and outer diameters of the brake disc can be positioned at multiple points at the same time, thereby improving the clamping stability.The positioning post 214 extends through the second turntable 212. A second contact block 216 is fixedly connected to the inner side of the second turntable 212. The end of the second contact block 216, which is closest to the second contact groove 215, is inserted into the inner side of the second contact groove 215. There are six groups of slide grooves 23, each arranged in a circular array around the centerline of the connecting disk 22. Each group of slide grooves 23 is slidably connected to a group of positioning blocks 24 at both ends. The bottom of the positioning block 24 near the center of the connecting disk 22 is fixedly connected to the circular block 25 located within the arcuate groove 213 defined on the surface of the second turntable 212. Meanwhile, the bottom of the positioning block 24 away from the center of the connecting disk 22 is fixedly connected to the circular block 25 located within the arcuate groove 1 28 defined on the surface of the first turntable 26.

A connecting plate 218 is fixedly connected to the side of the connecting disc 22. The connecting plate 218 passes through the processing chamber 21 and is slidably connected. The automobile brake disc to be processed is placed on the connecting disc 22 in the processing chamber 21, and then the cylinder 4 is started. The output shaft of the cylinder 4 drives the mounting platform 5 and the electric-controlled drill 6 at the bottom of the mounting platform 5 to descend together. When the mounting platform 5 moves downward, the pressure plate 223 on the side will move downward together. , and will gradually contact the rubber block 220, so that the rubber block 220 is pushed downward and drives the pushing column 219 to push the connecting plate 218. The top surface of the connecting plate 218 is fixedly connected with the pushing column 219, and the top surface of the pushing column 219 is fixedly connected with the rubber block 220. The inner side of the pushing column 219 is inserted into and slidably connected with a telescopic rod 221. A spring 1 222 is fixedly connected between the telescopic rod 221 and the inner side of the pushing column 219. The side of the mounting platform 5 is fixedly connected with a pressure plate 223.

[0033] When the cam 31 is in the unlock state, the locking plate 312 is unlocked and the locking plate 313 is unlocked, so that the cam 31 is unlocked and the locking plate 314 is unlocked. A support rod 36 is fixedly connected to the inner side of the positioning block 24, and the support rod 36 passes through and is slidably connected to the L-shaped rod 35. The side of the L-shaped rod 35 close to the limiting hole 33 is fixedly connected to the limiting rod 312, and a spring three 37 is sleeved on the outer side of the support rod 36. One end of the spring three 37 is fixedly connected to the inner wall of the positioning block 24, and the other end of the spring three 37 is fixedly connected to the surface of the L-shaped rod 35. The surface of the positioning block 24 is hinged with a trigger plate 38, and a torsion spring 39 is fixedly connected between the trigger plate 38 and the positioning block 24. The trigger plate 38 is fixedly connected to a hinge plate 310 on the side close to the positioning block 24, and the inner side of the hinge plate 310 is hinged with an insertion rod 311. During the positioning process, the linkage assembly 3 reinforces the vertical direction of the brake disc. When the positioning block 24 approaches and contacts the brake disc of the car, the positioning block 24 will first drive the trigger plate 38 to contact the edge of the brake disc, so that the trigger plate 38 is subjected to the resistance force and rotates to drive the hinge plate 310 to push the insertion rod 311 to insert into the inner side of the positioning block 24. The insertion rod 311 is inserted into the inner side of the positioning block 24 and is slidably connected to the positioning block 24. The side of the L-shaped rod 35 close to the insertion rod 311 is an inclined surface.

[0034] Working principle: When in use, first, place the automobile brake disc to be processed on the connecting disc 22 in the processing chamber 21, and then start the cylinder 4. The output shaft of the cylinder 4 drives the mounting platform 5 and the electric drill 6 at the bottom of the mounting platform 5 to descend together. When the mounting platform 5 moves downward, the pressure plate 223 on the side will move downward together, and will gradually contact the rubber block 220, so that the rubber block 220 is subjected to a downward thrust and drives the push column 219 to push the connecting plate 218. After the connecting plate 218 is thrust, it will drive the connecting disc 22 to move downward together, and the turntable 26 is located on the inner side of the connecting disc 22 and is rotatably connected to the connecting disc 22. The resistance block 210 connected to the side of the turntable 26 by the connecting rod 29 will move along the resistance groove 211 when following the turntable 26 and the connecting disc 22 to move downward. The first and second turntables 212 rotate coaxially with the first turntable 26, but the surface of the second turntable 212 is provided with an arc groove 213, and the round block 25 at the bottom of the positioning block 24 close to the center of the connecting disk 22 is inserted into the arc groove 213. The rotation of the first turntable 26 will push a group of positioning blocks 24 in the slide groove 23 to slide outward or inward along the slide groove 23 through the arc groove 28, thereby adapting to the outer diameter and inner diameter of the brake disc. When the second turntable 212 follows the first turntable 26 to move downward, the second turntable 212 slides in the second contact groove 215 through the fixed resistance block 216 on its inner side, ensuring the stable rotation of the second turntable 212. The second turntable 212 rotates coaxially with the first turntable 26, but the surface of the second turntable 212 is provided with an arc groove 213, and the round block 25 at the bottom of the positioning block 24 close to the center of the connecting disk 22 is inserted into the arc groove 213. When the second turntable 212 rotates, the second arc groove 213 pushes these positioning blocks 24 to move along the slide groove 23, thereby adapting to the inner diameter size of the brake disc. Therefore, the inner and outer diameters of the brake disc can be positioned at multiple points at the same time, thereby improving the clamping stability.

[0035] During the positioning process, the linkage assembly 3 reinforces the vertical direction of the brake disc. When the positioning block 24 approaches and contacts the automobile brake disc, the positioning block 24 will first drive the trigger plate 38 to contact the edge of the brake disc, so that the trigger plate 38 is subjected to the resistance force to rotate to drive the hinge plate 310 to push the insertion rod 311 to insert into the inner side of the positioning block 24, so that the insertion rod 311 contacts the inclined surface of the L-shaped rod 35, and then force the L-shaped rod 35 to shrink to both sides, so that the L-shaped rod 35 drives the limiting rod 312 to be pulled out of the limiting hole 33. Then, the spring 2 34, which is initially tightened, will instantly pull the square rod 31 downward, so that the square rod 31 pulls the locking block 32 to press the edge of the brake disc to prevent it from loosening during the drilling process.

[0036] After drilling is complete, cylinder 4 drives mounting platform 5 upward, pressing plate 223 disengages push column 219, and spring 1 222 resets. Connecting disc 22 also resets when connecting plate 218 resets, and positioning block 24 returns to its original position. Simultaneously, trigger plate 38 resets under the action of torsion spring 39, inserting rod 311 retracts, and limiting rod 312 disengages limiting hole 33 of square rod 31, allowing the completed brake disc to be removed. Throughout this process, positioning assembly 2 and linkage assembly 3 work in tandem to ensure the brake disc remains stable during drilling, improving machining accuracy and efficiency.
