[0036] Initially, the four first guide grooves 71 and the rear second guide grooves 72 are slidably connected with the fan-shaped frame 8, first, the wheel hub is placed on the placement seat 3, and then the left and right electric clamps 6 are started to move in the direction of approaching each other and contacting the wheel hub, the left and right electric clamps 6 clamp the wheel hub, and the servo motor 10 is started to drive the bevel gear 101 to rotate alternately forward and reverse, the bevel gear 101 drives the bevel gear 103 to rotate alternately forward and reverse, the bevel gear 103 rotates alternately forward and reverse, and the driving screw 102 rotates alternately forward and reverse, the screw drives the five sliders 81 to move synchronously inward and outward, and the sliders 81 drive the five drill rods 9 to move synchronously inward and outward, so as to adjust the hole spacing of the wheel hub, and when the drill rod 9 moves to the hole spacing position for drilling the wheel hub, the servo motor 10 is turned off, and the bevel gear 101 stops driving The movable bevel gear 103 rotates alternately forward and reverse, the slider 81 stops and drives the drill rod 9 to move inward and outward, then the drill rod 9 is started to rotate, and then the lifter 5 is started to drive the disc 7 to move downward, the disc 7 moves downward through the first guide groove 71 and the second guide groove 72 to drive the five fan-shaped frames 8 to move downward, the fan-shaped frame 8 moves downward to drive the slider 81 to move downward, the slider 81 moves downward to drive the drill rod 9 to move downward, the drill rod 9 moves downward and contacts the wheel hub, the drill rod 9 drills the wheel hub, and the debris produced by the drilling falls downward into the discharge frame 4, which is inclined with the bottom of the discharge frame 4, and the discharge frame 4 discharges and collects all the debris. When the wheel hub drilling is completed, the lifter 5 is started to drive the disc 7 to move upward and reset, and the disc 7 passes through the first guide groove 71 and the second guide groove 72. 2 drives the fan-shaped frame 8 to move upward and reset, the fan-shaped frame 8 resets and drives the drill rod 9 to move upward and reset through the slider 81, and then starts the electric screw 12 to rotate forward, the electric screw 12 rotates forward and drives the lifting plate 121 to move upward, the lifting plate 121 drives the inner spline cylinder 122 to move upward, the inner spline cylinder 122 moves upward and drives the spline shaft 123 to move upward through the connecting spring 125, the spline shaft 123 drives the grinding disc 124 to move upward, when the grinding disc 124 moves upward and contacts the bottom edge of the hole of the wheel hub, the electric screw 12 is turned off, the lifting plate 121 stops driving the inner spline cylinder 122 to move upward, the grinding disc 124 stops moving upward, due to the action of the connecting spring 125, the grinding disc 124 can be closely contacted with the bottom edge of the hole of the wheel hub, and starts The driving motor 126 drives the inner spline cylinder 122 to rotate, and the rotation of the inner spline cylinder 122 drives the spline shaft 123 to rotate, and the spline shaft 123 drives the grinding disc 124 to rotate, and the grinding disc 124 rotates to grind the bottom edge of the wheel hub hole, so that the burrs on the edge of the wheel hub hole are removed. In this way, the bottom of the wheel hub hole can be made smoother, which is convenient for subsequent processing. When the burrs on the bottom edge of the wheel hub hole are cleaned, the driving motor 126 is turned off, the spline shaft 123 stops driving the grinding disc 124 to rotate, and the electric screw rod 12 is started to reverse and drive the lifting plate 121 to move downward and reset, so that the grinding disc 124 moves downward and resets, and then the electric clamps 6 on the left and right sides are started to move and reset, and the electric clamps 6 loosen the five-hole wheel hub, and the five-hole wheel hub can be removed.This process is repeated repeatedly to continuously drill holes in the wheel hub, and the drilling process of the five holes in the wheel hub is completed. After the drilling of the wheel hub that needs to drill five holes is completed, the drill rod 9 is closed. When four holes need to be drilled in the wheel hub, the electric screw 112 is first started to rotate forward. The electric screw 112 rotates forward to drive the movable plate 11 to move upward through the thread. The movable plate 11 drives the limit ring 111 to move upward. The limit ring 111 moves upward to stop limiting the sector frame 8. The electric screw 112 is closed, and the four sector frames 8 in the first guide groove 71 are pulled outward so that the four sector frames 8 are out of contact with the first guide groove 71. Three of the sector frames 8 are pushed into the remaining three unused second guide grooves 72, and the four sector frames 8 are in a cross shape. The electric screw 112 is then started to reverse and drive the movable plate 11 to move downward and reset through the thread. The movable plate 11 drives the limit ring 111 to move downward and reset. The limit ring 111 resets to limit the four sector frames 8 to prevent the sector frames 8 from moving. The phenomenon affects the drilling accuracy of the drill rod 9 on the wheel hub, so as to ensure the drilling accuracy of the drill rod 9 on the wheel hub, start the drill rod 9 to rotate, and then start the elevator 5 to move downward to drive the disc 7 to move downward, so that the four drill rods 9 move downward to drill the wheel hub, and complete the drilling of the four holes of the wheel hub. When all the holes of the wheel hub that need to be drilled with four holes are drilled, close the drill rod 9, start the electric screw 112 to rotate forward again so that the limit ring 111 moves upward to stop limiting the fan frame 8, take out the fan frame 8 in the second guide groove 72 on the front side and the left and right sides, and then put the four fan frames 8 back to their original positions, start the electric screw 112 to reverse so that the limit ring 111 moves downward to reset and limit the fan frame 8, so that the wheel hub can be drilled with four holes and five holes, so as to meet the processing requirements and improve the adaptability.

[0037] Initially, the guide pipe 138 is connected to an external water source. When the lifter 5 drives the disc 7 to move downward, the disc 7 drives the shaft 13 to move downward, and the shaft 13 drives the L-shaped swing block 131 to move downward. The L-shaped swing block 131 moves downward and drives the contact block 133 to move downward through the compression spring 134. The contact block 133 and the L-shaped swing block 131 drive the elastic cloth 135 to move downward. The contact block 133 moves downward and contacts with the wheel hub first. The wheel hub limits the contact block 133. The contact block 133 stops moving downward. The contact block 133 stops driving the elastic cloth 135 to move downward. The elastic cloth 135 covers the upper part of the wheel hub. The L-shaped swing block 131 continues to move downward to compress the compression spring 134, and then the drill The rod 9 moves downward to drill the wheel hub, and the elastic cloth 135 blocks the debris generated during the drilling process. The blocked debris falls downward to the discharge frame 4 for discharge, and at the same time, the water is discharged into the guide pipe 138, and the water in the guide pipe 138 is discharged into the nozzle 139. The nozzle 139 sprays water on the wheel hub and the drill rod 9. The water can cool the drill rod 9 and the drilling position, and at the same time, the remaining debris can be flushed into the discharge frame 4. When the wheel hub drilling is completed, the water is stopped from being discharged into the guide pipe 138, and the nozzle 139 stops spraying water. The lifter 5 drives the disc 7 to move upward and reset. The disc 7 drives the L-shaped swing block 131 to move upward through the rotating shaft 13. The L-shaped swing block 131 moves upward to first make the pressure The compression spring 134 is reset, and then the L-shaped swing block 131 drives the contact block 133 to move upward and reset through the compression spring 134, and the contact block 133 and the L-shaped swing block 131 drive the elastic cloth 135 to move upward and reset. When the fan-shaped frame 8 needs to be removed, the electric screw 112 is started to move the limit ring 111 upward, and the limit ring 111 moves upward to drive the rack 137 to move upward, and the rack 137 moves upward to drive the spur gear 136 to rotate, and the spur gear 136 rotates to drive the shaft 13 to rotate, and the shaft 13 drives the L-shaped swing block 131 to swing upward by ninety degrees, and the L-shaped swing block 131 drives the contact block 133 to swing upward by ninety degrees through the slide bar 132, and the contact block 133 and the L-shaped swing block 13 1 swings upward 90 degrees to drive the elastic cloth 135 to swing upward. The upward swing of the elastic cloth 135 does not affect the removal of the fan-shaped frame 8. The electric screw 112 is turned off, and the fan-shaped frame 8 can be removed for adjustment. When the fan-shaped frame 8 is put back to its original position, the electric screw 112 is started to reverse so that the limit ring 111 moves downward and resets. The limit ring 111 drives the rack 137 to move downward and reset. The rack 137 drives the spur gear 136 to rotate in the opposite direction and reset. The spur gear 136 drives the L-shaped swing block 131 to swing downward and reset through the rotating shaft 13. The L-shaped swing block 131 drives the contact block 133 to swing downward and reset through the sliding rod 132. The contact block 133 and the L-shaped swing block 131 drive the elastic cloth 135 to swing downward and reset. In this way, it can prevent the debris generated by drilling from being ejected to the surroundings to affect the working environment, thereby ensuring a good working environment.

[0038] When the electric splints 6 on the left and right sides move toward each other, the electric splints 6 drive the buffer pads 14 to move, and the buffer pads 14 move to contact the wheel hub. The electric splints 6 clamp and fix the wheel hub through the buffer pads 14, and the buffer pads 14 protect the wheel hub. In this way, the electric splints 6 can be prevented from hard contact with the wheel hub to prevent damage to the wheel hub, thereby ensuring the finishing quality of the wheel hub.
