Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 7 As shown, the utility model provides a bolt thread rolling machine, including a base 1, a thread rolling plate 4 is movably installed above the base 1, an adjusting groove 15 is opened on the inner side of the thread rolling plate 4, an adjusting plate 16 is movably installed inside the adjusting groove 15, a thread rolling block 17 is fixedly installed on the outer side of the adjusting plate 16, the right end of the adjusting plate 16 is rotatably connected to the inside of the adjusting groove 15, a connecting shaft 18 is fixedly installed above the left end of the adjusting plate 16 and extends to the top of the thread rolling plate 4, a pulling block 20 is fixedly installed above the connecting shaft 18, a reset spring 19 is elastically installed between the inner side of the adjusting groove 15 and the upper side of the adjusting plate 16, and the reset spring 19 is movably connected to the outer side of the connecting shaft 18.

[0025] In this embodiment, when it is necessary to adjust the thread rolling spacing, it is only necessary to pull the pull block 20 so that the pull block 20 drives the connecting shaft 18 to move upward, and the connecting shaft 18 drives the adjustment plate 16 to move upward inside the adjustment groove 15, so that the adjustment plate 16 makes a circular motion around the right end of the adjustment plate 16, and the left end of the adjustment plate 16 moves upward, thereby squeezing the reset spring 19 and deforming the reset spring 19, and then fix the connecting shaft 18, thereby fixing the thread rolling block 17, and threading the bolt through the thread rolling block 17.

[0026] By pulling the pulling block 20, the adjusting plate 16 is driven upward by the pulling block 20 through the connecting shaft 18, so that the thread rolling block 17 moves upward, thereby reducing the thread rolling spacing, which is convenient for adjusting the thread rolling thread density. Compared with the traditional bolt thread rolling machine, this bolt thread rolling machine pulls the pulling block 20 to make the thread rolling block 17 move upward, thereby reducing the thread rolling spacing and increasing the thread density, which is convenient for the staff to use.

[0027] like Figure 5~Figure 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a bottom ring 21 located on the outside of the connecting shaft 18 is fixedly installed above the thread rolling plate 4, an elastic block 22 is fixedly installed above the bottom ring 21, a ramp block 23 is fixedly installed above the elastic block 22, an outer ring block 24 is fixedly installed on the outside of the bottom ring 21, a screw groove 25 is opened on the inner side of the outer ring block 24, a threaded shaft 26 is installed on the internal thread of the screw groove 25, and a rotating shaft 28 located below the pulling block 20 is fixedly installed above the threaded shaft 26.

The threaded shaft 26 rotates inside the screw groove 25 to drive the bevel ring 27 to move downward. The downward movement of the bevel ring 27 squeezes the bevel block 23, causing the bevel block 23 to move inward, driving the elastic block 22 to deform and move inward, so that the bevel block 23 and the outer ring block 24 squeeze the connecting shaft 18, thereby fixing the connecting shaft 18.

[0029] By rotating the shaft 28, the threaded shaft 26 rotates inside the screw groove 25, driving the bevel ring 27 to move downward to squeeze the bevel block 23, so that the bevel block 23 moves inward to drive the elastic block 22 to deform and fix the connecting shaft 18. Compared with the traditional bolt thread rolling machine, this bolt thread rolling machine fixes the connecting shaft 18 by rotating the shaft 28 to make the elastic block 22 and the bevel block 23 shrink inward, which is convenient for the staff to use.

[0031] In this embodiment, the bolts to be threaded are put into the inclined slot 3, and then the servo motor 5 is started to drive the disc 6 to rotate, and the disc 6 drives the connecting plate 8 to move left and right, and drives the thread rolling plate 4 to move left and right to thread the bolts.

[0032] like Figure 3 As shown, based on the same concept as the above-mentioned embodiment 4, this embodiment also proposes that a square plate 9 is fixedly installed on the right side of the thread rolling plate 4, a round shaft 10 is fixedly installed between the inner sides of the square plate 9, and the left end of the connecting plate 8 is movably sleeved on the outer side of the round shaft 10.

[0033] In this embodiment, the circular block 7 drives the connecting plate 8 to move left and right by performing circular motion, the connecting plate 8 drives the circular shaft 10 to move left and right, and the circular shaft 10 drives the thread rolling plate 4 to move left and right to perform thread rolling.

[0034] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes to open a limiting groove 11 on the top of the base 1, a limiting rod 12 is fixedly installed inside the limiting groove 11, and a limiting block 13 is movably sleeved on the outer side of the limiting rod 12, and the limiting block 13 is fixedly connected to the bottom of the thread rolling plate 4.

[0035] In this embodiment, the left and right movement of the thread rolling plate 4 drives the limiting block 13 to move left and right inside the limiting groove 11 , thereby limiting the thread rolling plate 4 .

[0036] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 5, this embodiment further proposes that a telescopic spring 14 is elastically installed between the inner side of the limiting groove 11 and the inner side of the limiting block 13, and the telescopic spring 14 is movably connected to the outer side of the limiting rod 12.

[0037] In this embodiment, the limit block 13 moves left and right around the limit rod 12 inside the limit slot 11 to squeeze the telescopic spring 14, causing the telescopic spring 14 to deform, thereby facilitating the limit block 13 to move inside the limit slot 11.

[0038] like Figure 7 As shown, based on the same concept as the above-mentioned embodiment 2, this embodiment further proposes that a bevel ring 27 is fixedly installed below the threaded shaft 26 , and the bevel ring 27 corresponds to the bevel block 23 .

[0039] In this embodiment, the bevel ring 27 moves downward to squeeze the bevel block 23 and the elastic block 22, causing them to shrink inward to fix the connecting shaft 18.

[0040] The working principle and use process of this utility model:

[0041] When the thread rolling spacing needs to be adjusted, it is only necessary to pull the pull block 20 so that the pull block 20 drives the connecting shaft 18 to move upward, and the connecting shaft 18 drives the adjusting plate 16 to move upward inside the adjusting groove 15, so that the adjusting plate 16 makes a circular motion around the right end of the adjusting plate 16, and the left end of the adjusting plate 16 moves upward, thereby squeezing the reset spring 19 and deforming the reset spring 19, and then fix the connecting shaft 18, thereby fixing the thread rolling block 17, and threading the bolt through the thread rolling block 17.

[0042] When the connecting shaft 18 needs to be fixed, it is only necessary to rotate the rotating shaft 28 so that the rotating shaft 28 drives the threaded shaft 26 to rotate. The threaded shaft 26 rotates inside the screw groove 25 and drives the bevel ring 27 to move downward. The downward movement of the bevel ring 27 squeezes the bevel block 23, causing the bevel block 23 to move inward, driving the elastic block 22 to deform and move inward, so that the bevel block 23 and the outer ring block 24 squeeze the connecting shaft 18, thereby fixing the connecting shaft 18.
