In order to solve the above problems, we propose an automatic centering clamping mechanism for rods. Utility Model Content

[0029] Example 2:

[0030] Reference Figure 1 , Figure 2 and Figure 3 A first sliding groove 8 is provided on the left side of the inner cavity of the support plate 2. A first slider 9 is slidably connected to both sides of the inner cavity of the first sliding groove 8. The right side of the first slider 9 is fixedly connected to the first threaded sleeve 303, which can limit and guide the movement of the first threaded sleeve 303, increasing the stability when the first threaded rod 302 drives the first threaded sleeve 303 to move.

[0031] The working principle is as follows:

[0032] In use, the base 1 can be installed and fixed through the mounting hole 12, increasing the stability of the clamping device. Then, the first motor 301 is started to drive the first threaded rod 302 to rotate. Due to the design of the positive and negative threads on the surface of the first threaded rod 302, the first threaded rod 302 drives the two first threaded sleeves 303 to move relative to each other. In turn, the two connecting blocks 304 can drive the two adjusting boxes 4 to move relative to each other. The rod 7 can be clamped according to its diameter, improving the convenience of clamping. Then, the second motor 501 is started to drive the second threaded rod 502 to rotate. The design of the positive and negative threads on the surface of the second threaded rod 502 drives the two second threaded sleeves 503 to move relative to each other. In turn, the bracket 504 can move relative to each other. The four positioning wheels 6 can be synchronously driven to adjust the spacing according to the diameter of the rod 7, so that the rod 7 can be clamped and fixed quickly. This makes it convenient for workers to frequently load, unload and clamp rods 7 of different diameters during the processing, improving processing efficiency.

[0033] In summary, this automatic centering and clamping mechanism for bar stock, by setting the first adjusting component 3, can drive the two adjusting boxes 4 to move relative to each other, and can clamp according to the diameter of the bar 7, improving the convenience of clamping. By setting the second adjusting component 5, it can further adjust the spacing of the four positioning wheels 6 synchronously according to the diameter of the bar 7, so as to quickly clamp and fix the bar 7. This makes it convenient for workers to frequently load, unload and clamp bars 7 of different diameters during the processing, thus improving processing efficiency.
