[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 As shown, a rotary tooth rolling machine includes a mechanism table 1, a motor 2 is fixedly connected to a mounting frame in the middle of the lower surface of the mechanism table 1, a mounting seat 3 is fixedly connected to the output end of the motor 2, and the mounting seat 3 is located on the upper side of the mechanism table 1, a first tooth rolling plate 4 is fixedly sleeved on the outer wall of the mounting seat 3, a guide plate 5 is fixedly connected to the rear middle position of the upper surface of the mechanism table 1, and an adjustment mechanism 6 is rotatably connected to the upper side of the mechanism table 1 near the left rear side.

[0025] It should be noted that the rear surface of the guide plate 5 is a slope slightly inclined to the right rear side, and the upper side of the guide plate 5 is used to hang the upper wall of the workpiece to be processed, and rely on the feeding mechanism to push the workpiece to be processed to the left.

[0026] like Figure 3-Figure 5As shown, the adjustment mechanism 6 includes a first helical gear 61, the lower side of the first helical gear 61 is rotatably connected to the lower surface of the inner side of the mechanism platform 1 near the left rear side, the inner side of the mechanism platform 1 near the left rear side is rotatably connected with two lead screws 62 symmetrically distributed front and back, the outer walls of the two lead screws 62 near the left end are fixedly connected with second helical gears 63, the sides of the second helical gears 63 close to each other are meshed and connected with the right rear and left front sides of the first helical gear 61, a knob 64 is fixedly connected to the upper axis of the first helical gear 61, the outer wall of the lead screw 62 is threadedly connected with a moving block 65, the upper side of the moving block 65 is fixedly connected with an arc-shaped top plate 66, and the arc-shaped top plate 66 is located on the left rear side of the mounting seat 3, and the inner middle part of the arc-shaped top plate 66 is fixedly sleeved with a second rubbing plate 67.

[0027] It should be noted that, by rotating the knob 64, the knob 64 drives the first helical gear 61 to rotate, the first helical gear 61 drives the second helical gear 63 to rotate, the second helical gear 63 drives the screw rod 62 to rotate, and the screw rod 62 drives the moving block 65 to move from the left rear to the right front side, so as to adjust the distance between the second rubbing plate 67 and the first rubbing plate 4, the motor 2 drives the mounting seat 3 to rotate, the mounting seat 3 drives the first rubbing plate 4 to rotate, and when the first rubbing plate 4 rotates, it squeezes the workpiece to be processed and processes the workpiece together with the second rubbing plate 67.

[0028] like Figure 5 As shown, the outer side of the knob 64 is provided with friction patterns.

[0029] It should be noted that the friction pattern is used to increase the friction between the hand and the knob 64 , making it easier for the user to turn the knob 64 .

[0030] like Figure 3 , Figure 4 As shown, a plurality of evenly distributed screws 68 are movably sleeved on the lower wall of the arc-shaped top plate 66 near the left rear side, the lower ends of the plurality of screws 68 are fixedly connected with a clamping plate 69, and the clamping plate 69 is located on the lower side of the mechanism platform 1, and the outer walls of the plurality of screws 68 are threadedly connected with a threaded seat 610, and the threaded seat 610 is located on the upper side of the arc-shaped top plate 66.

[0031] It should be noted that rotating the threaded seat 610 can drive the screw 68 to move up and down, thereby relying on the threaded seat 610 and the clamping plate 69 to clamp the lower wall of the mechanism table 1 and the arc-shaped top plate 66, so as to fix the arc-shaped top plate 66, avoiding uneven fixation during processing, resulting in the problem of one side warping.

[0032] like Figure 1 As shown, the upper surface of the mechanism table 1 is inclined toward the left front side as a whole.

[0033] It should be noted that the inclination of the upper surface of the mechanism table 1 allows the processed parts to move forward after processing, so as to be separated from the debris generated during processing and avoid being accumulated together with the debris generated during processing.

[0034] like Figure 2 As shown, a material leakage port is provided at the left rear side of the middle part of the upper surface of the mechanism platform 1 .

[0035] It should be noted that the material discharge port is used to discharge the debris generated by processing and the processed parts downward to avoid accumulation on the mechanism table 1.

The friction pattern is used to increase the friction between the hand and the knob 64, which is convenient for the user to turn the knob 64, and the material to be processed is pushed into the position between the first rubbing plate 4 and the second rubbing plate 67 along the guide plate 5 through the feeding mechanism, and then the motor 2 drives the second rubbing plate 6 7 The material to be processed is threaded to form a screw. Due to the rotation form, the return action of the traditional reciprocating thread rolling machine is cancelled, and the work efficiency of product processing is improved. Finally, the motor 2 drives the mounting seat 3 to rotate, and the mounting seat 3 drives the first thread rolling plate 4 to rotate. When the first thread rolling plate 4 rotates, it squeezes the workpiece to be processed and the second thread rolling plate 67 to process the workpiece together. By rotating the knob 64, the distance between the first thread rolling plate 4 and the second thread rolling plate 67 is adjusted, so that the thread rolling machine can adapt to a variety of materials to be processed with different coarseness and fineness, thereby improving the applicability of the thread rolling machine. At the same time, the screw rod 62 is used for adjustment to improve the adjustment accuracy.
