Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-11, the present invention provides a technical solution: a drilling device for carbon fiber automotive parts, including a base 1, the top of the base 1 is fixedly connected with a hydraulic cylinder 2, and the bottom corners are fixedly connected with support blocks 50. A push rod 3 is slidably connected in the hydraulic cylinder 2, and the top of the push rod 3 is fixedly connected with a fixed box 4; it also includes a drilling assembly 5, the drilling assembly 5 includes a bushing 6 fixedly connected to the fixed box 4, a rotating shaft 7 is rotatably connected in the bushing 6, the bottom end of the rotating shaft 7 is fixedly connected with a connecting piece 8, and a drill bit 9 is fixedly connected to the connecting piece 8 by bolts. Both the rotating shaft 7 and the drill bit 9 are hollow. The drilling assembly 5 drills the carbon fiber automotive parts through the drill bit 9; a cleaning assembly 10, the cleaning assembly 10 includes a wind hood 11 installed in the fixed box 4, a wind wheel 12 is rotatably connected in the wind hood 11, and the top is communicated with a discharge pipe 13 extending outside the fixed box 4. The cleaning assembly 10 is used to clean the residues remaining during the drilling process; a cutting and crushing assembly 14, the cutting and crushing assembly 14 includes a connecting block 15 installed in the drill bit 9, and multiple cutting blades 16 are fixedly connected to the outer surface of the connecting block 15. The cutting and crushing assembly 14 is used to cut the fragments left by the drilling. When drilling the carbon fiber automotive parts, the parts are adjusted to the correct position at this time, and then the parts are drilled through the drilling assembly 5. During the drilling process, the cutting and crushing assembly 14 and the cleaning assembly 10 operate. Therefore, the cutting and crushing assembly 14 cuts the fragments left after drilling, and the waste chips are collected through the action of the cleaning assembly 10.

[0030] The drilling assembly 5 includes a small gear 17 installed in the fixed box 4, the small gear 17 is fixedly connected to the rotating shaft 7, and a large gear 18 rotatably connected to the fixed box 4 is meshed outside it. A driving member 19 connected to the fixed box 4 is fixedly connected to the central position of the large gear 18. The driving member 19 is connected to the cleaning assembly 10. By starting the driving member 19, the large gear 18 is driven to rotate, then the small gear 17 is driven to rotate, and then the rotating shaft 7 is driven to rotate, so as to drive the drill bit 9 to rotate. Since the diameter of the large gear 18 is larger than that of the small gear 17, the large gear 18 will drive the small gear 17 to rotate at an accelerated speed, so as to drive the rotating shaft 7 and the drill bit 9 to rotate at an accelerated speed, improving the drilling efficiency.

[0031] The driving member 19 includes a support frame 20 fixedly connected to the fixed box 4, a motor 21 fixedly connected to the support frame 20, an output end of the motor 21 fixedly connected to a coupling 22, one end of the coupling 22 fixedly connected to a drive shaft 23 extending into the fixed box 4 and rotatably connected to the fixed box 4, the drive shaft 23 is fixedly connected to the large gear 18, by starting the motor 21, the motor 21 will drive the coupling 22 to rotate, and then drive the drive shaft 23 to rotate, thereby driving the large gear 18 to rotate.

[0032] The cleaning assembly 10 includes a transmission member 32 connected to the drive shaft 23 and a connecting ring 24 installed on the outer surface of the rotating shaft 7, and a plurality of dust suction pipes 25 are connected to the connecting ring 24, and a plurality of through grooves 26 are opened on the rotating shaft 23 at the position of the connecting ring 24, and a telescopic tube 27 is slidably connected to the dust suction pipe 25, and the outer surface of the telescopic tube 27 is connected to an elastic member 28 connected to the dust suction pipe 25. When the drive shaft 23 rotates, it will drive the transmission member 32 to operate, thereby driving the wind wheel 12 to rotate, and then the rotation of the wind wheel 12 generates suction, so that the waste chips left by the drilling are passed through the drill bit 9 and the hollow position in the rotating shaft 7 into the wind cover 11 by suction, and the generated suction makes the waste chips enter the dust suction pipe 25 through the telescopic tube 27, and then enter the hollow position of the rotating shaft 7 through the action of the through grooves 26, thereby entering the wind cover 11, and then the waste chips are discharged through the discharge pipe 13.

[0033] The elastic member 28 includes a first fixing ring 29 fixedly connected to the dust suction tube 25, one end of the first fixing ring 29 is fixedly connected to a first spring 30 sleeved on the outer surface of the telescopic tube 27, and one end of the first spring 30 is fixedly connected to a second fixing ring 31 fixedly connected to the telescopic tube 27. During the cutting process, when the drill bit 9 moves down to drill a hole, the telescopic tube 27 will move into the dust suction tube 25, thereby compressing the first spring 30. Therefore, after the drill bit 9 moves away from the part, the telescopic tube 27 is reset by the action of the first spring 30.

[0034] The transmission member 32 includes a driving wheel 33 fixedly connected to the drive shaft 23, and the outer surface of the driving wheel 33 is transmission-connected to a belt 34, and one end of the belt 34 is transmission-connected to a driven wheel 35 fixedly connected to the wind wheel 12. When the drive shaft 23 rotates, the driving wheel 33 will be driven to rotate, and then the belt 34 will be driven to rotate, and then the driven wheel 35 will be driven to rotate, thereby driving the wind wheel 12 to rotate.

[0035] The cutting and crushing assembly 14 includes a connecting column 36 fixedly connected to the connecting block 15. The top of the connecting column 36 is fixedly connected to a rotating column 37. The top of the rotating column 37 is fixedly connected to a rotating rod 38. The outer surface of the rotating rod 38 is slidably connected to a rotating sleeve 39 fixedly connected to the wind wheel 12. A second spring 40 fixedly connected to the rotating rod 38 is fixedly connected inside the rotating sleeve 39. And a telescopic member 41 is connected to the outer surface of the rotating column 37. When the wind wheel 12 rotates, it will drive the rotating sleeve 39 to rotate, then drive the rotating rod 38 to rotate, then drive the rotating column 37 to rotate, then drive the connecting column 36 to rotate, and then drive the cutting tool head 16 to rotate, so as to cut and crush the fragments. And due to the action of the telescopic member 41, the cutting tool head 16 moves up and down reciprocally, thus improving its cutting and crushing efficiency.

[0036] The telescopic member 41 includes a rotating ring 42 fixed to the outer surface of the rotating column 37. A connecting rod 43 is fixedly connected to the outer surface of the rotating ring 42. One end of the connecting rod 43 is rotatably connected to a roller 44. The outer surface of the roller 44 is movably connected to a mounting ring 45. A plurality of groups of wedge-shaped grooves 46 are formed in the mounting ring 45. When the rotating column 37 rotates, it will drive the rotating ring 42 to rotate, thus driving the connecting rod 43 to rotate, thus driving the roller 44 to rotate. Therefore, through the action of the mounting ring 45 and the wedge-shaped grooves 46, it drives the rotating column 37, the connecting column 36 and the cutting tool head 16 to move up and down. And when moving upward, the second spring 40 will be compressed. When moving downward, due to the elastic force of the second spring 40 being instantaneously released, the cutting tool head 16 impacts the fragments, thus improving the cutting and crushing efficiency.

[0037] Positioning members 51 are slidably connected to both the connecting block 15 and the connecting column 36. The positioning member 51 includes a positioning rod 47 slidably connected to the connecting block 15 and the connecting column 36. Sliding grooves 48 adapted to the positioning rod 47 are formed in both the connecting block 15 and the connecting column 36. A third spring 49 fixedly connected to the positioning rod 47 is fixedly connected inside the sliding groove 48. When drilling, the hydraulic cylinder 2 moves to drive the drill bit 9 to move downward, and then the positioning rod 47 is pushed to the central position of the position where drilling is required. Thus, through the action of the positioning rod 47, it is beneficial to improve the drilling accuracy. And when drilling, the positioning rod 47 retracts into the sliding groove 48, so it does not affect drilling and cutting and crushing. And due to the action of the third spring 49, it is convenient for the positioning rod 47 to reset.

[0038] When drilling carbon fiber automotive parts, the parts are adjusted to the correct position, and the hydraulic cylinder 2 is moved to drive the drill bit 9 downward. As a result, the positioning rod 47 is pushed to the center position of the location where drilling is required, which helps to improve the drilling accuracy by the action of the positioning rod 47. (During drilling, the positioning rod 47 retracts into the chute 48, so it does not affect drilling and cutting, and due to the action of the third spring 49, it is convenient for the positioning rod 47 to reset.) After positioning, the motor 21 is started. Then the motor 21 will drive the coupling 22 to rotate, which drives the drive shaft 23 to rotate, thus driving the large gear 18 to rotate, then driving the small gear 17 to rotate, then driving the rotating shaft 7 to rotate, and thus driving the drill bit 9 to rotate. Since the diameter of the large gear 18 is larger than that of the small gear 17, the large gear 18 will drive the small gear 17 to rotate at an accelerated speed, thus driving the rotating shaft 7 and the drill bit 9 to rotate at an accelerated speed, improving the drilling efficiency. When the drive shaft 23 rotates, it will drive the driving wheel 33 to rotate, then drive the belt 34 to rotate, then drive the driven wheel 35 to rotate, thus driving the wind wheel 12 to rotate. Then, through the rotation of the wind wheel 12, suction is generated. Therefore, the waste chips left by drilling enter the wind hood 11 through the hollow positions in the drill bit 9 and the rotating shaft 7. And due to the suction generated, the waste chips enter the dust suction pipe 25 through the telescopic pipe 27, and then enter the hollow position of the rotating shaft 7 through the through slot 26, thus entering the wind hood 11, and then the waste chips are discharged through the discharge pipe 13. (During the cutting process, when the drill bit 9 moves downward for drilling, the telescopic pipe 27 will move into the dust suction pipe 25, thus compressing the first spring 30. Therefore, after the drill bit 9 moves away from the part, the telescopic pipe 27 is reset by the action of the first spring 30.) And when the wind wheel 12 rotates, it will drive the rotating sleeve 39 to rotate, then drive the rotating rod 38 to rotate, then drive the rotating column 37 to rotate, then drive the connecting column 36 to rotate, and thus drive the cutting head 16 to rotate, so as to cut the fragments. And when the rotating column 37 rotates, it will drive the rotating ring 42 to rotate, thus driving the connecting rod 43 to rotate, and thus driving the roller 44 to rotate. Therefore, through the action of the mounting ring 45 and the wedge-shaped groove 46, the rotating column 37, the connecting column 36 and the cutting head 16 move up and down. When moving upward, the second spring 40 will be compressed, and when moving downward, due to the elastic force of the second spring 40 being instantaneously released, the cutting head 16 will impact the fragments, thus improving the cutting efficiency.
