When the cold drawing mold needs to be replaced, it cannot be adjusted according to the height of the mold, which affects the use range of the device and cannot meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture of a seamless steel pipe cold drawing machine, comprising a base and a mounting platform fixedly connected to the top of the base, a lifting mechanism extending to the top of the mounting platform is arranged inside the mounting platform, and a driving mechanism is arranged on the top of the mounting platform;

[0016] Compared with the prior art, the utility model provides a clamp for a seamless steel pipe cold drawing machine, which has the following beneficial effects:

[0017] 1. The clamp of the seamless steel pipe cold drawing machine drives the lifting platform to move up and down by setting a telescopic cylinder, which is convenient for adjusting the clamping height. Then, by setting a slider and a hinge, when the lifting platform is lifted or lowered, the hinge rod will be driven to rotate. When the hinge rod rotates, the hinge and the slider will move, thereby stabilizing the lifting platform and improving the stability of the lifting platform when it is lifted or lowered.

[0018] 2. The clamp of the seamless steel pipe cold drawing machine drives the first pulley to rotate by setting a driving motor, and then drives the transmission belt and the second pulley to rotate through the rotation of the first pulley, so that the second pulley can drive the bidirectional threaded rod to rotate, thereby facilitating the clamping and fixing of the seamless steel pipe through the clamping plate, solving the problem that only seamless steel pipes of a specific height can be clamped. When the cold drawing mold needs to be replaced, it cannot be adjusted according to the height of the mold, thereby affecting the use range of the device and failing to meet production needs.
