[0033] In this embodiment, in order to achieve the effect of firmly clamping the bolts and adjusting according to different types of bolts, an installation and fixing component 4 is designed. A transverse screw 4-2 driven to rotate by the first motor 4-1 is arranged inside the support frame 3, and movable frames 4-3 are installed at both ends of the transverse screw 4-2, which can be moved laterally by the rotation drive of the transverse screw 4-2. A connecting hole 4-4 is opened at one end of the movable frame 4-3, and a clamping frame 4-5 can be inserted. The clamping frame 4-5 is replaced according to the diameter of the bolt. After being inserted into the connecting hole 4-4, it is fixed by bolts, which makes it convenient to disassemble and replace the clamping frames 4-5 of different sizes. At the same time, the bottom hydraulic rod 4-7 can be adjusted according to the length of the bolt. The support block 4-8 ​​at the output end of the hydraulic rod 4-7 is used to support the bottom of the bolt and cooperate with stamping to play a fixing role.

[0034] Specifically, in order to achieve a stable stamping effect on the bolts, a force pressure driving assembly 5 is designed to ensure that the stamping part maintains a vertical and stable movement downward.

[0035] Furthermore, the pressure drive assembly 5 includes a second motor 5-1, which is installed on the top of the frame body 1. A lead screw 5-2 is rotatably connected to the side frame 2, and a transmission gear 5-3 is provided at the upper end of the lead screw 5-2 and the output end of the second motor 5-1. A vertical rod 5-4 is fixedly connected to the side frame 2, and a lifting frame 5-5 is connected to the outside of the lead screw 5-2 by threaded fitting.

A transmission gear 5-3 is installed on the top of the screw 5-2 and the output end of the second motor 5-1. The transmission gear 5-3 can be used to drive the screw 5-2 to rotate through the second motor 5-1 as a power. A lifting frame 5-5 is connected to the surface of the screw 5-2 through threaded cooperation. A pressure block 5-6 is provided on the bottom surface of the lifting frame 5-5. The lifting frame 5-5 is driven by the screw 5-2 to move vertically downward, so that the pressure block 5-6 punches the bolts, and the vertical rod 5-4 is used to strengthen the stability of the lifting frame 5-5.

[0037] Furthermore, the transverse screw 4-2 is a double-start thread structure and the thread directions at both ends are positive helix and reverse helix respectively.

[0038] In this embodiment, the transverse screw rod 4-2 drives the moving frames 4-3 at both ends to move transversely through the threads of the positive and negative helices, so that the clamping frame 4-5 can clamp the bolts while keeping the bolts in the accurate axial position.

[0039] Furthermore, a buffer spring 6 is sleeved and connected to the outside of the vertical rod 5 - 4 .

[0040] In this embodiment, the buffer spring 6 can provide a shock-absorbing and buffering effect to the lifting frame 5 - 5 during movement.

[0041] Furthermore, the pressure block 5-6, the clamping frame 4-5 and the hydraulic rod 4-7 are located on the same axis.

[0042] In this embodiment, it is ensured that the pressure block 5-6, the clamping frame 4-5 and the hydraulic rod 4-7 maintain the same axial center state, so that the bolts maintain an accurate stamping state and will not deviate.

[0043] Furthermore, a supporting layer 7 is provided on the upper end surface of the clamping frame 4 - 5 .

[0044] In this embodiment, the support layer 7 is used to increase the force-bearing surface of the top of the clamping frame 4 - 5 , so that the pressure block 5 - 6 can punch the bolt more stably and effectively.

[0045] When the bolt needs to be stamped, take out the clamping frame 4-5 that matches the bolt, insert the clamping frame 4-5 into the connecting hole 4-4 of the moving frame 4-3 and insert the fixing bolt 4-6 to fix it, then start the hydraulic rod 4-7 according to the height of the bolt, adjust the height of the support block 4-8, during processing, use the tool to put the heated bolt between the clamping frames 4-5, then start the first motor 4-1, drive the horizontal screw 4-2 to rotate, so that the movement is more simultaneous and moves toward the middle, so that the clamping frame 4-5 clamps both sides of the bolt, then start the second motor 5-1, the transmission gear 5-3 at the output end of the second motor 5-1 drives the lead screw 5-2 to rotate, so that the lifting frame 5-5 moves vertically downward to stamp the bolt.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
