[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A drilling assembly and a driving assembly are provided. The motor can drive the drill bit to rotate through the first shaft, the first rectangular column and the two second gears, thereby rotating the piston body. The air pump applies pressure to the first piston cylinder through the three-way joint and the connecting pipe, pushing the first movable plug and the first push column to move upward. The first push column can drive the second piston cylinder and the drill bit to move upward to drill the piston body.

[0017] 2. The air pump can increase pressure into the second piston cylinder through the three-way joint and the pressure pipe, pushing the second movable plug and the second push column upward to extend the drill bit. When the drill bit is tightly pressed against the piston body, the piston body can support the drill bit. When the pressure in the second piston cylinder reaches a certain intensity, the pressure relief valve can automatically relieve pressure to ensure stability, so that the drill bit will not squeeze the piston body too hard and cause damage to the drill bit, thereby playing a buffering role.

[0018] 3. A chamfering assembly and a transmission assembly are set up. The motor can drive the third round rod to rotate through the first conical teeth and the second conical teeth. The third round rod drives the reciprocating screw to rotate at a low speed through two third gears and the reduction box. The reciprocating screw can drive the movable plate and the two milling cutters to move back and forth; at the same time, the third round rod can drive the first rotating shaft and the two milling cutters to rotate through the second rectangular column, the second rotating shaft and the transmission belt, thereby chamfering the piston body.

[0019] 4. A clamping assembly is provided. When the second piston cylinder moves upward to drill the piston body, the second piston cylinder can drive the two first racks to move upward through the two support columns. The two first racks move downward through the two first gears and the two second racks to drive the clamping plate to move downward, so that the piston body can be clamped stably and conveniently. When the drilling is completed and the second piston cylinder moves downward, the clamping plate can be driven upward by the two first racks, the two second racks and the two first gears to release the piston body, thereby realizing an automatic release operation.

[0020] 5. A positioning component is set. When the piston body is placed on the placement groove, one end of the piston body can be placed on the rubber stopper to position the piston body. At the same time, the piston body can be rotated by the rotating tube. After the processing is completed, the piston body can be directly taken out of the placement groove by pulling out the moving tube, which is convenient for use and increases practicality.

[0021] 6. A chip removal assembly is set up. The first conical tooth can drive the fan blade to rotate quickly through the third conical tooth and the second shaft. The fan blade can suck the iron chips in the piston body through the chip suction bucket, and then suck them into the collection box through the moving tube and hose. The iron chips generated during the processing can be collected for easy cleaning.

[0022] To sum up, the present invention can perform chamfering work at the same time as drilling the piston body, without the need to replace equipment, thereby reducing production costs and improving work efficiency. It can also firmly and conveniently clamp and position the piston body for easy use, and can also collect iron filings generated during the processing, which is convenient for cleaning and increases practicality.

The first top column 24 is slidably provided on the top of the first piston cylinder 22. The outer end of the first top column 24 is fixedly provided on the bottom of the second piston cylinder 26. The bottom end of the second piston cylinder 26 is penetrated by a pressure relief valve 216. The pressure relief valve 216 is a prior art. When the air pressure in the second piston cylinder 26 reaches a certain intensity, the pressure relief valve 216 can automatically relieve the pressure. The second movable piston 27 is slidably provided on the second piston cylinder 26, a second top column 28 is fixedly provided on the top of the second movable piston 27, a connecting plate 29 is fixedly provided on the top of the second top column 28, a drill bit 210 is rotatably provided on the top of the connecting plate 29, an air pump 211 is fixedly installed on the bottom of the operating table 1, and the output end of the air pump 211 is fixedly connected to a three-way joint 212, and the other two ends of the three-way joint 212 are respectively fixedly connected to a connecting pipe 213 and a pressurizing pipe 214, and the other end of the connecting pipe 213 passes through the bottom end of the first piston cylinder 22 and is fixed.

[0054] 2. The air pump 211 applies pressure to the first piston cylinder 22 through the three-way joint 212 and the connecting pipe 213, pushing the first movable piston 23 and the first push column 24 to move upward. The first push column 24 drives the second piston cylinder 26 and the drill bit 210 to move upward. The second piston cylinder 26 drives the two first racks 32 to move upward through the two support columns 31. The two first racks 32 drive the two second racks 35 to move downward through the two first gears 37. The two second racks 35 can drive the clamping plate 34 to move downward through the two vertical plates 33, thereby clamping and fixing the piston body 9.

[0055] 3. The air pump 211 can also apply pressure to the second piston cylinder 26 through the three-way connector 212 and the pressure pipe 214, pushing the second movable plug 27 and the second push column 28 upward, extending the drill bit 210, and pressing it against the piston body 9 to perform drilling. At the same time, the piston body 9 can press against the drill bit 210 and press against the second movable plug 27 through the second push column 28. When the pressure in the second piston cylinder 26 reaches a certain level, the pressure relief valve 216 can automatically perform a pressure relief operation to avoid squeezing and damaging the drill bit 210.

[0056] 4. At the same time, the motor 41 drives the third rod 63 to rotate through the first bevel gear 65 and the second bevel gear 64. The third rod 63 drives the cylinder 66 to rotate through the two third gears 67. The cylinder 66 drives the reciprocating screw 54 to rotate at a low speed through the reduction box 53. The reciprocating screw 54 can drive the movable plate 51 to move back and forth. The movable plate 51 drives the two milling cutters 510 to move back and forth through the first rotating shaft 58.

[0057] 5. The third round rod 63 can also drive the second rotating shaft 61 to rotate through the second rectangular column 62. The second rotating shaft 61 can drive the first rotating shaft 58 and the two milling cutters 510 to rotate through two pulleys 68 and a transmission belt 69. When the two milling cutters 510 are tightly pressed against the piston body 9, chamfering can be performed.

[0058] 6. At the same time, the first bevel gear 65 can drive the fan blade 87 to rotate rapidly through the third bevel gear 88 and the second shaft 86. The fan blade 87 can suck the iron chips in the piston body 9 through the chip suction bucket 83, and then suck them into the collection box 81 through the moving tube 72 and the hose 82 to collect the iron chips.

[0059] 7. Then, the staff opens the electric valve 25 through the controller 10 to relieve the pressure in the first piston cylinder 22, so that the second piston cylinder 26 and the drill bit 210 move downward under the action of gravity. The two first racks 32, the two second racks 35 and the two first gears 37 can drive the clamping plate 34 to move in the opposite direction to loosen the piston body 9. At this time, the piston body 9 can be rotated through the movable tube 72, and the drilling operation can be repeated on the other side of the piston body 9. After the processing is completed, the piston body 9 is loosened and the piston body 9 can be pulled out through the movable tube 72. Finally, the processed piston body 9 is removed and the processing of the next piston body 9 can be continued.
