Description

Technical Field

[0001] This invention relates to the field of punching equipment technology, specifically to a precision machining equipment for brake disc mounting holes. Background Technology

[0002] As a key safety component in the automotive braking system, the machining accuracy of the mounting holes of the brake disc directly affects the concentricity of the brake disc installation, dynamic balance, and the braking stability of the entire vehicle. Currently, among the machining processes for brake disc mounting holes, punching is widely used in mass production due to its advantages such as high production efficiency and good material utilization.

[0003] In the prior art, punching equipment used for processing brake disc mounting holes uses a stamping mechanism to drive a punch to punch and shape the brake disc blank. For example, the invention patent with authorization announcement number CN120268910B discloses a single punching die for punching and trimming the brake wheel of an automobile brake disc, and the utility model patent with authorization announcement number CN210208301U discloses a high-speed brake disc mold. Such equipment generally operates continuously in cycles to perform punching actions. After one punching action is completed, the equipment usually defaults to directly entering the next cycle. When the cutting head is worn or damaged, if it cannot be detected in time, the equipment will continue to operate with the defect, resulting in problems such as dimensional deviations, insufficient roundness, and reduced hole wall quality in the subsequently processed brake disc mounting holes. Consequently, it is impossible to guarantee the high precision and high stability of brake disc mounting hole processing. Summary of the Invention

[0030] The unloading mechanism includes a conveyor belt device 49, two fifth telescopic cylinders 50, and two support frames 51. The two support frames 51 are horizontally and longitudinally fixedly installed on the side of the power slide device 2. The two fifth telescopic cylinders 50 are vertically fixedly installed inside the two support frames 51. The conveyor belt device 49 is horizontally fixedly installed on the top of the two fifth telescopic cylinders 50.

[0031] This equipment processes the mounting holes of the brake disc by applying pressure and forming the mounting holes through punching.

[0032] When punching the brake disc, the concave side of the brake disc to be punched is placed on the upper side of the support block 13 near the outer shell 7. Under the action of gravity, the spring 16 is compressed, and the pressure rod 14 drives the pressure ring 17 to move down. The inner ring sidewall of the brake disc contacts multiple balls 27. Under the action of multiple compression springs 25, the brake disc moves to the center position. Then the motor 18 starts and drives the truss 6 to deflect 180 degrees through the meshing of the second gear 20 and the third gear 21. Then the motor 18 self-locks, fixing the truss 6. At this time, the brake disc to be punched moves to the bottom side of the stop block 24 and then the punching operation is performed.

[0033] During punching, the first telescopic cylinder 23 extends, pushing the pressure ring 17 upward. The pressure ring 17 drives multiple pressure rods 14 and multiple die cutters 15 to move upward, applying an upward push to the brake disc. Under the squeezing force of the stop block 24 and the die cutter 15, the brake disc is punched out of the mounting hole, and the excess waste is discharged through the top of the drain hole 241 in the stop block 24. At the same time, the second telescopic cylinder 28 extends, driving the electromagnet device 29 to move downward. The electromagnet device 29 is energized to attract the waste discharged from the drain hole 241, and then moves upward to reset. The third telescopic cylinder 30 extends, driving the scraper 31 to move and push the waste at the bottom of the electromagnet device 29. After being pushed to the upper side of the guide plate 32, the electromagnet device 29 is de-energized, releasing the attraction force, and the waste falls onto the guide plate 32 and is discharged. Then the third telescopic cylinder 30 shortens, driving the scraper 31 to reset.

[0034] After punching is completed, the motor 18 starts, driving the truss 6 to rotate 180 degrees again, rotating the brake disc that has completed the punching operation to the side closer to the outer shell 7, and then locking itself. The power slide device 2 moves, causing the conveyor belt devices 49 on both sides to move to the bottom side of the brake disc. Then, the upper sides of the four fifth telescopic cylinders 50 make the upper sides of the two conveyor belt devices 49 contact the bottom side of the brake disc. As the fifth telescopic cylinders 50 extend, the brake disc finally disengages from the die cutter 15. Then, the two conveyor belt devices 49 start, transferring the brake disc to the next station.

[0035] Subsequently, the power slide device 2 is activated, causing the outer shell 7 to engage with the outside of the support block 13. The power slide device 2 stops sliding. Then, the first motor 9 is activated, driving the rack 11 to rotate via the first gear 10. The rack 11 drives the inner shell 8 to rotate, cooperating with the outer shell 7 to seal the support block 13. Then, the fourth telescopic cylinder 33 extends, causing the connecting frame 34 to move multiple sleeves 35 downwards. Finally, the multiple sleeves 35 are respectively fitted onto multiple die cutters 15, and the multiple brush heads inside contact the die cutters 15. Then, the second motor 36 and the pump body device 39 are activated. The second motor 36 drives... The fifth gear 38 drives multiple fourth gears 37 to rotate synchronously. The fourth gears 37 drive the sleeves 35 connected to them to rotate. The sleeves 35 rotate on the white surface of the die cutter 15 through the internal brush head to scrape and wash the die cutter 15. At the same time, the pump body device 39 draws cleaning fluid from the storage tank 40 through the liquid extraction pipe 41 and injects it into the ring pipe 43 through the hose 42. Finally, it is injected into multiple sleeves 35 through multiple diversion pipes 44 to rinse the die cutter 15. With the scraping of the brush head in the sleeve 35, the surface of the die cutter 15 that has just completed the processing operation is thoroughly cleaned.

[0036] After cleaning is completed, the pump body device 39 and the second motor 36 stop operating, and the fourth telescopic cylinder 33 is in multiple stages, causing the sleeve 35 to separate from the die cutter 15. Then, multiple sets of visual inspection devices 5 on the top and sides collect image data of multiple die cutters 15, and inspect their surface and dimensions to ensure that the die cutter 15 is in good condition and to avoid machining accuracy deviations caused by defects in the die cutter 15 itself, thereby ensuring the accurate machining of the mounting holes.

[0037] The visual inspection device 5 uses existing technology, combining optical three-dimensional measurement technology with automated software algorithms, to collect data on the appearance of the die cutter 15 and feed it back to the computer system. The automated software algorithm analyzes the data and indicates whether the corresponding die cutter 15 is intact. If all die cutters 15 are in good condition, the next brake disc is processed. If any die cutter 15 is damaged, it is replaced in time.

[0038] After the power slide device 2 slides into place, the sealing plate 46 contacts the bottom of the pressure ring 17 and supports it. During the cleaning process, the cleaning waste liquid flows out through the overflow hole 133 and eventually gathers in the inner ring of the pressure ring 17, where it is intercepted by the sealing plate 46. The filter device 47 draws the waste liquid through the middle of the sealing plate 46, filters it, and then introduces it into the storage tank 40 for the next use.

[0039] After the test is completed, the first motor 9 rotates in the reverse direction, causing the inner shell 8 to reset. Then, the power slide device 2 moves in the reverse direction to reset. Based on the test results, the die cutter 15 is selectively replaced or reused. Then, the next brake disc that needs to be punched is placed on top of the die cutter 15 for the next processing cycle.

[0040] With the cooperation of the testing agency, the die cutter 15 that has completed the processing can be cleaned and inspected in a timely manner, so as to replace the die cutter 15 in a timely manner and ensure that the die cutter 15 itself is in good condition. This eliminates the processing errors caused by the defects of the die cutter 15 itself, and thus ensures the accurate processing of the brake disc mounting hole.

[0041] With the cooperation of the shifting component, the two sets of tool assemblies can be switched alternately, thereby enabling loading, unloading and punching operations to be carried out simultaneously, thus improving the efficiency of machining mounting holes.

[0042] With the cleaning component in operation, the surface of the die cutter 15 can be thoroughly cleaned, thereby removing metal shavings from the surface of the die cutter 15 in a timely manner to avoid interference with the inspection and subsequent punching operations. At the same time, the cleaning fluid can cool down the die cutter 15, thereby maintaining the die cutter 15.
