The outer surfaces of the two connecting frames 10 are movably connected to the inner surfaces of the fixing frame 12 and the mounting frame 4 respectively. The rotation of the rotating plate 8 will cause the connecting frame 10 to move vertically up and down.

[0032] When the driving motor 6 starts to run, the rotating shaft 7 will drive the rotating plate 8 to rotate, and the sleeve rod 9 will start to move. At this time, due to the limiting effect of the mounting frame 4 and the fixing frame 12, the connecting frame 10 will move vertically up and down, thereby achieving the purpose of adjusting the spacing between the thread rolling plates.

[0034] When the first motor 15 starts to operate, the rotating rod 16 will rotate.

[0035] Among them, the other end of the rotating rod 16 is fixedly sleeved with a gear 17, and the top and bottom of the outer surface of the gear 17 are meshed and connected with tooth plates 18. There are two tooth plates 18, and the interiors of the two tooth plates 18 are movably sleeved with the outer surface of the limiting rod 13.

[0045] The working principle and use process of this utility model:

[0046] First, after rotating and opening the rotating plate 21, the bolt to be processed is placed on the thread rolling plate, and then the first motor 15 is started, so that the rotating rod 16 drives the gear 17 to rotate. At this time, under the limiting action of the limiting rod 13, the toothed plate 18 drives the connecting plate 19 and the fixed plate 20 to move horizontally toward each other, thereby driving the mounting frame 4 and the fixed frame 12 to start moving together under the limiting action of the limiting plate 11 and the transverse groove 3, and the thread rolling operation will be carried out at this time. When the thread rolling depth needs to be increased, the driving motor 6 is started, so that the rotating shaft 7 drives the rotating plate 8 to rotate, thereby driving the sleeve rod 9 to move, and then the connecting frame 10 is under the limiting action of the mounting frame 4 and the fixed frame 12. Vertical movement towards each other, the function of adjusting the thread rolling depth is realized, which not only reduces the labor intensity of the operator, but also improves the application scope of the device.

[0047] When the thread rolling plate becomes worn out during long-term use and needs to be replaced, the second motor 22 is started, so that the rotary rod 23 drives the inclined plate 24 to rotate, thereby causing the connecting rod 25 to move. At this time, under the limiting effect of the connecting frame 10, the four clamping plates 26 will move along the outer surface of the connecting frame 10 in the direction away from the thread rolling plate, and finally the clamping and fixing effect on the thread rolling plate is released, thereby achieving the purpose of facilitating the disassembly and assembly of the thread rolling plate, reducing the labor intensity of the operator, and improving the efficiency of the operator in replacing the thread rolling plate.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
