[0016] A processing device for a polygonal inner hole comprises a machine base, a main shaft is provided on the machine base, a fixture for clamping a workpiece is provided on the main shaft, a toothed disk is provided on the fixture, a punching device is provided on the right side of the fixture, the punching device comprises a rotating disk, a transverse shaking rod, a tool mounting seat rotatably arranged on the machine base, and a cutting tool mounted on the tool mounting seat, the front end of the cutting tool faces the fixture, a rotating groove is provided on the rotating disk, the rear end of the transverse shaking rod is arranged in the rotating groove and abuts against the inner wall of the rotating groove, a pushing device is provided on one side of the rear end of the transverse shaking rod, one end of the pushing device abuts against the rear end of the transverse shaking rod, the front end of the transverse shaking rod is connected to the tool mounting seat, and the rotation of the rotating disk can drive the rear end of the transverse shaking rod The tool mounting seat shakes left and right, and the tool mounting seat shakes left and right along with the transverse shaking rod. The front end of the cutting tool makes a reverse movement relative to the rear end of the transverse shaking rod, and an inner hole with the same profile as the rotating groove is opened on the workpiece. A transmission device is also provided between the toothed disc and the rotating disc. After the toothed disc rotates, the rotating disc is driven to rotate synchronously through the transmission device. A sliding seat is also provided on the machine base, and the punching device is arranged on the sliding seat. A longitudinal driving device is also provided on the machine base to push the sliding seat to move back and forth on the machine base; the user can fix the workpiece with a through hole through the clamp, and the user can set the processing program of the processing device before use, so that the longitudinal driving component that drives the sliding seat to move back and forth can cooperate with the processing program. The longitudinal driving component is the processing device The common power device on the equipment is composed of a screw and a motor. The screw is threadedly connected to the sliding seat. Before the workpiece processing begins, the longitudinal drive assembly will push the sliding seat toward the fixture so that the cutting tool can just contact the port of the through hole on the workpiece. When the spindle starts working, it will drive the fixture to rotate. At this time, the spindle will drive the gear disc to rotate together after working. Since there is a transmission device between the gear disc and the rotating disk, the gear disc will drive the rotating disk to rotate through the transmission device after rotating, so that the gear disc and the rotating disk rotate synchronously. The shape of the rotating groove on the rotating disk is a regular polygon, such as: regular hexagon, regular pentagon and regular quadrilateral, etc. The user can customize the rotating disk according to the shape of the inner hole he wants to open on the workpiece. Since one end of the horizontal shaking rod is set in the rotating groove and is connected to the rotating disk The inner walls of the movable groove abut against each other. When one end of the transverse shaking rod is at the intersection of the two sides of the polygon, the rotating disk will drive the rear end of the transverse shaking rod to move a distance toward the axis of the rotating disk after rotation. At this time, the tool mounting seat connected to the front end of the transverse shaking rod will move in the opposite direction to the rear end of the transverse shaking rod, thereby driving the front end of the cutting tool on the tool mounting seat to move in the opposite direction relative to the rear end of the transverse shaking rod. When the rotating disk continues to rotate, it will reach the next intersection. At this time, the rear end of the transverse shaking rod moves outward and re-enters the intersection. At this time, the transverse shaking rod completes a transverse reciprocating motion, and the tool mounting seat and the cutting tool also complete a transverse reciprocating motion. Since the toothed disc is driven to rotate by the fixture, the rotation frequency of the workpiece on the fixture and the toothed disc is the same.Thereby, the rotation frequency of the workpiece and the rotating disk is also the same, and the cutting tool will cut an oblique cutting surface on the inner wall of the port of the through hole of the workpiece, and the repeated cutter head will cut a polygon with the same shape as the rotating groove at the port of the through hole, and the pushing device is arranged on one side of the horizontal shaking rod and abuts against the horizontal shaking rod, so that the horizontal shaking rod goes out from the first intersection and reaches the next intersection. The pushing device can push the horizontal shaking rod to smoothly enter the next intersection, so that the reciprocating motion of the horizontal shaking rod can be carried out smoothly. Compared with the CNC punching machines and laser equipment with polygonal inner holes on the market, when the port processing of the through hole on the workpiece is completed, the previously set processing program will control the longitudinal The driving assembly pushes the sliding seat forward a certain distance, allowing the cutting head to enter the middle end of the through hole. At this time, the cutting head repeatedly cuts a polygon with the same shape as the rotating groove in the middle end of the through hole. In this way, the cutting head will repeatedly cut a polygonal inner hole with the same shape as the rotating groove and a deeper depth in the through hole of the workpiece. This can effectively solve the problem that CNC punching machines and laser equipment cannot open very deep polygonal inner holes on the workpiece. The cutting tool will not cause damage to the workpiece during the process of opening the polygonal inner hole on the workpiece, making the cutting of the polygonal inner hole more accurate. The processing cost of the workpiece processed by CNC punching machines and laser equipment will be higher. The utility model can effectively reduce the processing cost of the workpiece.

After the toothed disk 2 rotates, the rotating disk 7 is driven to rotate synchronously through the transmission device. A sliding seat 50 is also provided on the machine base 1, and the punching device is arranged on the sliding seat 50. The machine base 1 is also provided with a longitudinal drive device that can push the sliding seat 50 to move back and forth on the machine base 1; the user can fix the workpiece with a through hole through the clamp 3, and use Before use, the user can set the processing program of the processing device in advance so that the longitudinal drive component that drives the sliding seat 50 to move back and forth can cooperate with the processing program. The longitudinal drive component is a common power device on the processing equipment. For example, it is composed of a screw and a motor. The screw is threadedly connected to the sliding seat 50. Before the workpiece processing starts, the longitudinal drive component will push the sliding seat 50 to move toward the clamp 3 so that the cutting tool 51 can just contact the port of the through hole on the workpiece. When the main shaft 4 starts working, it will drive the clamp 3 to rotate. At this time, the main shaft 4 will drive the gear disc 2 to rotate together after working.

Since one end of the transverse shaking rod 8 is arranged in the rotating groove 9 and abuts against the inner wall of the rotating groove 9, when one end of the transverse shaking rod 8 is at the intersection of the two sides of the polygon, the rotating disk 7 will drive the rear end of the transverse shaking rod 8 to move a distance toward the axis of the rotating disk 7 after rotation.

There are currently CNC punching machines and laser equipment on the market that can open polygonal inner holes. In the present invention, after the end processing of the through hole on the workpiece is completed, the previously set processing program will control the longitudinal drive assembly to push the sliding seat 50 forward a certain distance, so that the cutting head enters the middle end of the through hole. At this time, the head repeatedly cuts a polygon with the same shape as the rotating groove 9 at the middle end of the through hole. In this way, the head will repeatedly cut a polygonal inner hole with the same shape as the rotating groove 9 and a deeper depth in the through hole of the workpiece, which can effectively solve the problem that CNC punching machines and laser equipment cannot open very deep polygonal inner holes on the workpiece. In addition, the cutting tool 51 will not cause damage to the workpiece during the process of opening the polygonal inner hole on the workpiece, making the cutting of the polygonal inner hole more accurate. In addition, the processing cost of the workpiece processed by the CNC punching machine and laser equipment will be higher.
