Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and particularly to a drilling equipment for the production of automotive brake discs. Background Art

[0002] The drilling equipment for brake disc production is mainly used to accurately process ventilation holes and mounting holes on the brake disc to ensure heat dissipation performance and mounting accuracy. Such equipment usually adopts a high-rigidity structural design to meet the processing requirements of hard materials such as cast iron or composite materials, and is equipped with a multi-axis numerical control system to achieve automatic drilling, enabling efficient processing of multiple hole positions simultaneously. The core components of the equipment include a high-precision spindle unit, a servo drive system, and a rigid drill chuck, which are combined with a coolant system to reduce drill bit wear. Advanced models integrate vision positioning or laser detection functions to correct hole position deviations in real time, ensuring that the hole diameter tolerance is controlled within ±0.02 mm. Some production lines use a robot loading and unloading unit to achieve unmanned production, and the processing cycle can reach 15 - 20 seconds per piece. The equipment must have functions such as broken tool detection and tool life management, prevent processing abnormalities through vibration sensors, and at the same time use a chip collection device to handle the metal chips generated during drilling to meet environmental protection requirements. Modern drilling equipment realizes cloud optimization of processing parameters through the industrial Internet, significantly improving the processing quality and production efficiency of brake disc drilling.

[0003] When drilling automotive brake discs, in actual work, it is necessary to drill brake discs of different sizes. However, each time when fixing brake discs of different sizes, the inner and outer diameters of the brake discs are different, and different fixtures need to be used or the size of the fixture needs to be adjusted repeatedly, which affects the drilling efficiency of the brake disc. Moreover, when initially fixing the brake disc, most of the existing drilling equipment only fixes the outer side of the brake disc through the fixture. When the brake disc is drilled, it will be subjected to a vertical vibration force, and the vertical direction of the brake disc is not fixed synchronously, which is likely to cause relatively large wear between the side surface and the fixture during the drilling of the brake disc, thus affecting the subsequent processing of the brake disc.

[0015] The drilling processing equipment for automobile brake disc production of the present invention has at least the following beneficial effects: 1.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] A drilling processing device for the production of automotive brake discs, such as Figure 1 - Figure 10As shown in the figure, it includes a bracket 1, a cylinder 4 and a mounting table 5. An electric control drill bit 6 is provided on the bottom surface of the mounting table 5. A placing table 7 is fixedly connected to the inner side of the bracket 1. The output shaft of the cylinder 4 is fixedly connected to the top surface of the mounting table 5. It also includes a positioning component 2 for simultaneously positioning the inner and outer diameters of automotive brake discs of different sizes, and a linkage component 3 for strengthening the vertical direction of the automotive brake disc when simultaneously fixing the inner and outer diameters of the automotive brake disc. The positioning component 2 includes a processing chamber 21. The bottom surface of the processing chamber 21 is fixedly connected to the top surface of the placing table 7. A connecting disc 22 is slidably connected to the inner side of the processing chamber 21. A chute 23 is provided on the surface of the connecting disc 22. A positioning block 24 is slidably arranged inside the chute 23. Since an arc-shaped groove 28 is provided on the surface of the first turntable 26, and the round block 25 at the bottom of the positioning block 24 away from the center of the connecting disc 22 is inserted into the arc-shaped groove 28, the rotation of the first turntable 26 will push a group of positioning blocks 24 in the chute 23 to slide outward or inward along the chute 23 through the arc-shaped groove 28, so as to adapt to the outer diameter and inner diameter dimensions of the brake disc. The bottom surface of the positioning block 24 is fixedly connected to a round block 25. A first turntable 26 is rotatably connected to the inner side of the connecting disc 22. An anti-detachment ring 27 is fixedly connected to the top surface of the first turntable 26. The anti-detachment ring 27 is located inside the connecting disc 22 and is rotatably connected to the connecting disc 22. An arc-shaped groove 28 is provided on the surface of the first turntable 26. A connecting rod 29 is fixedly connected to the side surface of the first turntable 26. One end of the connecting rod 29 away from the first turntable 26 is fixedly connected to a first abutting block 210. A first abutting groove 211 is provided inside the processing chamber 21. One end of the first abutting block 210 close to the first abutting groove 211 is inserted into the inner side of the arc-shaped abutting groove 211. A second turntable 212 is rotatably connected to the inner side of the first turntable 26. After the connecting plate 218 is subjected to a thrust force, it will drive the connecting disc 22 to move downward together. The first turntable 26 is located inside the connecting disc 22 and is rotatably connected to the connecting disc 22. When the first abutting block 210 connected to the side surface of the first turntable 26 by the connecting rod 29 moves downward following the first turntable 26 and the connecting disc 22, it will slide along the first abutting groove 211, thereby causing the first turntable 26 to rotate. An arc-shaped groove 213 is provided on the surface of the second turntable 212. A positioning column 214 is fixedly connected to the inner side of the processing chamber 21. An abutting groove 215 is fixedly connected to the surface of the positioning column 214. When the second turntable 212 moves downward following the first turntable 26, the second abutting block 216 fixed to its inner side slides in the abutting groove 215 to ensure the stable rotation of the second turntable 212. The second turntable 212 rotates coaxially with the first turntable 26, but an arc-shaped groove 213 is provided on the surface of the second turntable 212. The round block 25 at the bottom of the positioning block 24 close to the center of the connecting disc 22 is inserted into the arc-shaped groove 213. When the second turntable 212 rotates, the arc-shaped groove 213 pushes these positioning blocks 24 to move along the chute 23, so as to adapt to the inner diameter dimension of the brake disc. Therefore, the inner and outer diameters of the brake disc can be simultaneously positioned at multiple points, improving the clamping stability.The positioning post 214 penetrates through the second turntable 212. A second abutting block 216 is fixedly connected to the inner side of the second turntable 212. One end of the second abutting block 216 close to the second abutting groove 215 is inserted into the inner side of the second abutting groove 215. The number of the sliding grooves 23 is six groups, and the six groups of sliding grooves 23 are respectively arranged in a circumferential array with the center line of the connecting plate 22 as the axis. A positioning block 24 is slidably connected to both ends of each group of sliding grooves 23. The round block 25 fixedly connected to the bottom of the positioning block 24 close to the center of the connecting plate 22 is located in the second arc groove 213 opened on the surface of the second turntable 212. At the same time, the round block 25 fixedly connected to the bottom of the positioning block 24 far from the center of the connecting plate 22 is located in the first arc groove 28 opened on the surface of the first turntable 26. An activity groove 217 is opened on the side surface of the connecting plate 22. The connecting rod 29 passes through the activity groove 217. A connecting plate 218 is fixedly connected to the side surface of the connecting plate 22. The connecting plate 218 passes through the processing bin 21 and is slidably connected. The automobile brake disc to be processed is placed on the connecting plate 22 in the processing bin 21. Then, the air cylinder 4 is started. The output shaft of the air cylinder 4 drives the mounting table 5 and the electric control drill bit 6 at the bottom of the mounting table 5 to descend together. When the mounting table 5 moves downward, the pressing plate 223 on the side surface will move downward together and will gradually contact the rubber block 220, so that the rubber block 220 is subjected to a downward thrust to drive the pushing column 219 to push the connecting plate 218. A pushing column 219 is fixedly connected to the top surface of the connecting plate 218. A rubber block 220 is fixedly connected to the top surface of the pushing column 219. A telescopic rod 221 is inserted into and slidably connected to the inside of the pushing column 219. A first spring 222 is fixedly connected between the telescopic rod 221 and the inside of the pushing column 219. A pressing plate 223 is fixedly connected to the side surface of the mounting table 5.

[0022] The linkage assembly 3 includes a square rod 31, which is inserted into the inner side of the positioning block 24 and is slidably connected to the positioning block 24. The top of the square rod 31 is fixedly connected to a locking block 32. 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, so that the insertion rod 311 resists the inclined surface of the L-shaped rod 35, thereby forcing 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. Limiting holes 33 are provided on both sides of the square rod 31, and a spring 2 34 is fixedly connected between the bottom end of the square rod 31 and the inner side of the positioning block 24. 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 an 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. A trigger plate 38 is hinged on the surface of the positioning block 24, and a torsion spring 39 is fixedly connected between the trigger plate 38 and the positioning block 24. A hinge plate 310 is fixedly connected to the side of the trigger plate 38 close to the positioning block 24, and a plug rod 311 is hinged on the inner side of the hinge plate 310. 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 automobile, 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 rotated by the resistance force to drive the hinge plate 310 to push the plug rod 311 to insert into the inner side of the positioning block 24. The plug 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 plug rod 311 is an inclined surface.

[0023] Working principle: When in use, first, place the automobile brake disc to be processed on the connecting plate 22 in the processing chamber 21, and then start the cylinder 4, and drive the mounting platform 5 and the electric-controlled drill 6 at the bottom of the mounting platform 5 to descend together through the output shaft of the cylinder 4. 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 subjected to the thrust, it will drive the connecting plate 22 to move downward together, and the turntable 26 is located on the inner side of the connecting plate 22 and is rotatably connected to the connecting plate 22. The contact block 210 connected to the side of the turntable 26 by the connecting rod 29 will move along the contact groove 211 when following the turntable 26 and the connecting plate 22 to move downward. The rotating disk 212 slides and slides, thereby causing the rotating disk 26 to rotate. Since an arc groove 28 is provided on the surface of the rotating disk 26, and the round block 25 at the bottom of the positioning block 24 far away from the center of the connecting disk 22 is inserted into the arc groove 28, the rotation of the rotating disk 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, so as to adapt to the outer diameter and inner diameter of the brake disc. When the rotating disk 212 moves downward following the rotating disk 26, the abutment block 216 fixed on its inner side slides in the abutment groove 215 to ensure the stable rotation of the rotating disk 212. The rotating disk 212 rotates coaxially with the rotating disk 26, but an arc groove 213 is provided on the surface of the rotating disk 212, 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 the positioning blocks 24 to move along the slide groove 23 to adapt 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 to improve the clamping stability.

[0024] 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 rotated by the resistance force 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, thereby forcing 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 in a tightened state, 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.

[0025] After the drilling is completed, the air cylinder 4 drives the mounting table 5 to rise, the pressing plate 223 disengages from the pushing column 219, the first spring 222 resets, and the connecting plate 22 will reset together when the connecting plate 218 resets. At the same time, the positioning block 24 retracts to its original position. Meanwhile, the trigger plate 38 resets under the action of the torsion spring 39, the insertion rod 311 retracts, and the limiting rod 312 disengages from the limiting hole 33 of the square rod 31, and then the machined brake disc can be taken out. During the whole process, the positioning assembly 2 and the linkage assembly 3 work together to ensure the stability of the brake disc during drilling, improving the machining accuracy and efficiency.
