[0037] When the fourth motor 29 is running, the second rotating shaft 18 will drive the supporting block 19 to start rotating as a whole.

[0038] Among them, the upper surface of the support block 19 is fixedly connected with the installation box 20, the upper surface of the support block 19 is movably connected with the workpiece 27 located outside the installation box 20, the upper surface of the installation box 20 is fixedly connected with the cover plate 21, the inner surface of the support block 19 is fixedly installed with the No. 3 motor 22 located below the installation box 20, and the other end of the output shaft of the No. 3 motor 22 is fixedly sleeved with a round shaft 23, and the top end of the round shaft 23 passes through the installation box 20 and extends to the inside of the installation box 20.

[0039] When the third motor 22 is running, the circular shaft 23 will start to rotate slowly in the opposite direction to the overall rotation direction of the support block 19 .

[0040] Among them, the outer surface of the circular shaft 23 is fixedly sleeved with a rotating plate 24 located inside the installation box 20, the lower surface of the rotating plate 24 is movably connected to the inner surface of the installation box 20, and the upper surface of the rotating plate 24 is hinged with a connecting block 25. The number of the connecting blocks 25 is three, and the three connecting blocks 25 have the same size.

[0041] When the circular shaft 23 rotates, the rotating plate 24 as a whole will rotate driven by the circular shaft 23, and the three connecting blocks 25 will also start to rotate.

[0042] Among them, the other ends of the three connecting blocks 25 are hinged with fixed blocks 26, the number of the fixed blocks 26 is three, the outer ends of the three fixed blocks 26 all penetrate the installation box 20 and extend to the outside of the installation box 20, and the outer surface of the fixed block 26 and the inner surface of the installation box 20 are movably connected.

[0043] When the three connecting blocks 25 start to rotate driven by the rotating plate 24 , the other ends of the three connecting blocks 25 push the three fixing blocks 26 , so that the three fixing blocks 26 start to move toward the inner surface of the workpiece 27 under the limit of the inner surface of the installation box 20 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator places the workpiece 27 on the upper surface of the support block 19 and makes the installation box 20 as a whole located on the inner side of the workpiece 27, and then starts the No. 3 motor 22. As the No. 3 motor 22 runs, the circular shaft 23 and the rotating plate 24 begin to rotate. At this time, the three connecting blocks 25 rotate driven by the rotating plate 24. At the same time, the other ends of the three connecting blocks 25 respectively drive the three fixed blocks 26, so that the three fixed blocks 26 begin to move toward the inner surface of the workpiece 27 under the limit of the inner surface of the installation box 20. Finally, when the three fixed blocks 26 contact the inner surface of the workpiece 27, the workpiece 27 will be fixed by the three fixed blocks 26.

[0046] At this time, the operator starts the pneumatic cylinder 12, the No. 2 motor 15 and the No. 4 motor 29. The operation of the pneumatic cylinder 12 will cause the connecting column 13, the protective cover 14 as a whole and the gear rolling cutter 17 to start moving up and down. The operation of the No. 2 motor 15 will cause the No. 1 rotating shaft 16 to drive the gear rolling cutter 17 to rotate slowly. The operation of the No. 4 motor 29 will cause the No. 2 rotating shaft 18 and the supporting block 19 as a whole to rotate with the same angular velocity as the gear rolling cutter 17 but in the opposite direction. Finally, under the joint action of the gear rolling cutter 17 and the workpiece 27, the gear rolling cutter 17 will complete the toothing operation on the outer surface of the workpiece 27.

[0047] When the teeth are tied, the operator starts motor No. 1 5. As motor No. 1 5 runs, the double-threaded screw 6 starts to rotate, and the two movable blocks 28 start to move toward each other along the inner surface of the limit sleeve 4 driven by the double-threaded screw 6. The movement of the two movable blocks 28 will also drive connecting rod No. 1 7 and make it start to rotate with the top of the movable block 28 as the axis, and the other end of connecting rod No. 1 7 will drive connecting rod No. 2 8 and make it start to rotate. Similarly, connecting rod No. 3 9 will also be driven by connecting rod No. 2 8. At this time, the other end of connecting rod No. 3 9 will start to push the push plate 10, so that the push plate 10 starts to move backward along the inner surface between the workbench 1 and the fixed plate 2. In this process, the push plate 10 will push the iron filings on the inner surface between the workbench 1 and the fixed plate 2, and finally make them fall on the outside of the workbench 1 as a whole, thereby avoiding the operator from performing additional cleaning operations.
