[0043] The blocking component includes a sealing plate 19, two telescopic cylinders 20 and two connecting frames 21. The sealing plate 19 is vertically slidably sleeved in the ferrule 4 and is slidably sleeved with multiple drill rods 6. The two connecting frames 21 are vertically fixedly installed on the upper sides of both ends of the sealing plate 19.

The top ends of the two telescopic cylinders 20 are fixedly connected to the bottom sides of the top ends of the two connecting frames 21.

[0044] The bearing component includes two trusses 22 and a chuck 23. The two trusses 22 are horizontally opposed to each other, and the two ends far away from each other are fixedly connected to the sides of the two supports 8 close to each other. The chuck 23 is horizontally arranged between the two sets of drilling mechanisms, and the bottom surface is fixedly connected to the upper sides of the two trusses 22. The middle part of the chuck 23 passes through, and a plurality of plug rods 24 are evenly and vertically fixedly installed on the upper side in a ring shape. The plurality of plug rods 24 correspond to the mounting holes of the brake disc respectively.

[0045] The driving mechanism includes a second motor 30, an upper clamping rod 31 and a lower clamping rod 32. The second motor 30 is vertically fixedly installed in the middle of the upper side of the base 1 through a frame 33. The upper clamping rod 31 is vertically fixedly sleeved in the gear ring 17 located on the upper side. The lower clamping rod 32 is vertically slidably sleeved on the output shaft of the second motor 30 and fixedly sleeved with the gear ring 17 located on the bottom side. The ends of the upper clamping rod 31 and the lower clamping rod 32 that are close to each other are respectively provided with mutually matching slots 312, and torque is transmitted through the engagement of the slots 312.

[0046] When using this equipment for operation, the brake disc that needs to be drilled is sleeved on the chuck 23, and the mounting holes of the brake disc are made to correspond to multiple plug rods 24 respectively, so as to realize horizontal fixation of the brake disc, and then the first motor 29 is started, the first motor 29 drives the main shaft 27 to rotate, the main shaft 27 drives the two first sprocket wheels 25 to rotate, the two first sprocket wheels 25 respectively drive the corresponding second sprocket wheels 26 to rotate through two second chains 28, the second sprocket wheels 26 drive the pin shaft 11 to rotate, the pin shaft 11 drives the first gear 10 to rotate, and the first gear 10 drives the two racks 9 on the same side to move up and down at the same time, thereby driving the upper and lower support plates 3 and the ring body 2 to approach each other and move toward the brake disc.

[0047] As the ring body 2 moves, the two groups of multiple ferrules 4 on the upper and lower sides contact the upper and lower sides of the brake disc respectively at the same time, thereby fixing the brake disc in the vertical direction, thereby achieving rapid fixation of the brake disc, and the operation is relatively convenient and quick.

[0048] As the ring body 2 continues to move, the transmission shaft 7 moves, the transmission shaft 7 drives the middle drill rod 6 to move, and the drill rod 6 drives the clamping plate 5 to move downward, so that multiple drill rods 6 move synchronously and contact the brake disc.

[0049] After the ferrule 4 is in close contact with the brake disc, the pump device 42 is started, and the pump device 42 injects coolant into the conduit 43 through the hose 44. Since the ferrule 4, the sealing plate 19 and the brake disc form a closed structure, the coolant is sealed.

[0050] When the two ring bodies 2 are close to each other, the ring bodies 2 drive the gear rings 17 , and the two gear rings 17 respectively drive the upper clamping rod 31 and the lower clamping rod 32 to engage through the slots 312 , thereby realizing torque transmission.

[0051] After the coolant is injected, the second motor 30 starts, driving the lower clamping rod 32 to rotate, and the lower clamping rod 32 drives the upper clamping rod 31 to rotate, thereby driving the two gear rings 17 to rotate respectively, and the gear ring 17 drives multiple second gears 18 meshing with it to rotate, and the second gear 18 drives the transmission shaft 7 to rotate, and the transmission shaft 7 drives the drill rod 6 connected to it to rotate, and the middle drill rod 6 drives the other drill rods 6 to rotate through the main sprocket 14 and the auxiliary sprocket 15 and the first chain 16, so as to realize the rotation of the drill rod 6 and perform drilling operations on the brake disc.

[0052] When the drill rod 6 rotates, the power components operate synchronously, so that the ring body 2 drives the transmission shaft 7 to rotate and move, and the ring body 2 compresses the spring 13. The elastic force of the spring 13 acts on the pressure plate 12, and the pressure plate 12 transmits the pressure to the ferrule 4, so that the ferrule 4 is tightly against the brake disc. The two ferrules 4 facing each other up and down are both tightly against the brake disc, so that the brake disc is evenly stressed and displacement is avoided, thereby ensuring the accuracy of the drilling operation.

[0053] Multiple punching components operate simultaneously, punching holes on both sides simultaneously, forming multiple holes at one time and improving efficiency.

[0054] A plurality of magnets 35 are fixedly embedded on the bottom side of the sealing plate 19. A cleaning mechanism is provided on the rear side of the base 1. The cleaning mechanism includes a moving component and a scraping frame 36. The scraping frame 36 is vertically arranged, and the rear end is connected to the moving component.

[0055] The area of ​​the drill rod 6 located inside the sealing plate 19 is a polished rod, and is sealed and sleeved with the sealing plate 19 .

[0056] The moving assembly includes a frame 37, two guide rods 38, a screw 39 and a third motor 40. The frame 37 is vertically fixedly installed on the upper side of the base 1. The two guide rods 38 are horizontally fixedly installed in the frame 37 and are arranged up and down. The rear end of the scraper frame 36 is slidably sleeved on the two guide rods 38. The screw 39 is horizontally rotatably sleeved in the frame 37 and is located between the two guide rods 38. The screw 39 is threadedly connected to the scraper frame 36. The third motor 40 is fixedly installed on the side of the frame 37 through the base 41, and the output shaft is fixedly connected to the end of the screw 39 through a coupling.

[0057] During the punching process, the metal chips generated are sealed in the ferrule 4 to avoid splashing, and the metal chips are adsorbed by the magnet 35 at the bottom of the sealing plate 19, which can prevent the metal chips from gathering around the hole and scratching, thereby further ensuring the punching quality.

[0058] After the drilling is completed, the pump device 42 is operated to pump back the coolant, the power component operates in the reverse direction, the two sets of drilling mechanisms move away from each other, and the vertical limit on the brake disc is released. After the drilling is completed, the brake disc can be removed.

[0059] After the brake disc is removed, the telescopic cylinder 20 is shortened, so that the connecting frame 21 drives the sealing plate 19 to move to the end where the ferrule 4 is close to each other, thereby exposing the adsorbed metal chips to the outside of the ferrule 4, and then the third motor 40 is operated to rotate the screw 39, and the screw 39 drives the scraper frame 36 to slide under the support of two guide rods 38. During the movement of the scraper frame 36, the upper and lower sides respectively contact multiple sealing plates 19 to scrape off the metal chips to achieve cleaning, and then the telescopic cylinder 20 is reset to carry out the drilling operation of the next brake disc.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
