[0001] The utility model relates to the technical field of thread rolling machines, in particular to a fine-pitch thread rolling machine. Background Art

[0002] Thread is one of the indispensable standard parts in life, and its application involves various fields. According to the pitch size of the thread, it can be divided into coarse thread and fine thread. Coarse thread is generally used in situations where the bearing force is large, while fine thread is generally used to prevent loosening and in situations where sealing is required. It can also play a role in fine-tuning and has a wide range of applications. The thread rolling machine is a device specially used for producing screws.

[0003] However, the existing thread rolling machines generally cannot adjust the support rods used to support the workpiece, which makes it difficult to adjust the thread processing length of the workpiece, resulting in poor applicability. In addition, the spacing between the two thread rolling plates is difficult to adjust quickly and accurately, resulting in poor flexibility. Adjusting the thread rolling plates takes a long time, which affects processing efficiency.

[0004] In order to solve this technical problem, the utility model proposes a fine thread rolling machine. Utility Model Content

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

[0024] like Figure 1-5 As shown, a fine thread rolling machine includes a first mounting plate 1 and a second mounting plate 2. The outer end of the first mounting plate 1 is connected to a movable thread rolling plate 3. The first mounting plate 1 and the movable thread rolling plate 3 are both provided with connecting holes, and the connecting holes of the two are correspondingly arranged. By connecting bolts in the connecting holes, the movable thread rolling plate 3 can be connected and fixed to the outer end of the first mounting plate 1. The outer end of the second mounting plate 2 is connected to a fixed thread rolling plate 4. The second mounting plate 2 and the fixed thread rolling plate 4 are both provided with connecting holes, and the connecting holes of the two are correspondingly arranged. The movable thread rolling plate 3 and the fixed thread rolling plate 4 have the same structure, and the side ends are both provided with thread rolling grooves. The workpiece is in the thread rolling grooves of the two. Through the movement of the movable thread rolling plate 3, the surface of the workpiece will be extruded into a threaded shape.

[0025] A first electric push rod 5 is provided at the side end of the first mounting plate 1, and the driving end of the first electric push rod 5 is connected to the fixed support rod 6. The first electric push rod 5 can adjust the height of the fixed support rod 6, and the fixed support rod 6 is located at the upper end of the movable thread rolling plate 3, and the side ends of the two are flush. The side end of the second mounting plate 2 is connected to the second electric push rod 7, and the driving end of the second electric push rod 7 is connected to the movable support rod 8. The second electric push rod 7 is used to adjust the height of the movable support rod 8, and the movable support rod 8 is located at the upper end of the fixed thread rolling plate 4, and the side ends of the two are flush. The outer surfaces of the fixed support rod 6 and the movable support rod 8 are smooth, so that the workpiece can be easily rolled between the two.

[0026] The side end of the second mounting plate 2 is connected to a transverse electric push rod 9, which can drive the second mounting plate 2 to move, so as to adjust the spacing between the fixed thread rolling plate 3 and the movable thread rolling plate 4. The first electric push rod 5, the second electric push rod 7, and the transverse electric push rod 9 have the same structure, including a motor, a threaded rod, and a movable rod. The motor can drive the threaded rod to rotate, so that the movable rod can move, so that the length can be adjusted. A height measuring instrument 10 is connected to the fixed support rod 6 and the movable support rod 8. The side end of the movable support rod 8 is connected to a spacing measuring instrument 11. The spacing measuring instrument 11 is used to detect the spacing between the fixed support rod 6 and the movable support rod 8. The height measuring instrument 10 and the spacing measuring instrument 11 are both laser measurements, and their detection data are accurate. The height measuring instrument 10 in the fixed support rod 6 is connected to the first electric push rod 5 by a wire, and the height measuring instrument 10 in the movable support rod 8 is connected to the second electric push rod 7 by a wire.

[0027] A photoreceptor 12 is connected to the side end of the fixed support rod 6. The spacing measuring instrument 11 hits the laser on the photosensitive film of the photoreceptor 12. When the photoreceptor 12 is irradiated by the laser, it can generate a signal, which means that the fixed support rod 6 and the movable support rod 8 are at the same height. When the photoreceptor 12 generates no signal, it means that the heights of the fixed support rod 6 and the movable support rod 8 are inconsistent. At this time, it will be difficult for the workpiece to roll smoothly between the two, and the device needs to be stopped for maintenance. The spacing measuring instrument 11 is connected to the horizontal electric push rod 9 through a wire.

[0028] The side end of the first mounting plate 1 is connected to a connecting block 13, and the connecting block 13 is connected to a driving device, so that the driving device can push the first mounting plate 1 to move, thereby enabling the movable thread rolling plate 3 to move. The side end of the first mounting plate 1 is provided with a long fixed plate 14, and a track rod 15 is connected to the long fixed plate 14. The first mounting plate 1 is slidably connected to the outer end of the track rod 15, and the track rod 15 is used to support the first mounting plate 1. The first electric push rod 5 is connected to the long fixed plate 14, and the side end of the second mounting plate 2 is provided with a short fixed plate 16. The transverse electric push rod 9 is connected to the short fixed plate 16, and fixing holes are provided in the long fixed plate 14 and the short fixed plate 16.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
