Fixing device for grinding machining of valve element

The utility model relates to the technical field of valve element grinding machining, in particular to a fixing device for valve element grinding machining, and aims to solve the problems that in the prior art, valve elements are difficult to adaptively fix according to the specifications of the valve elements, different clamps need to be replaced for clamping the valve elements with different specifications, and the machining efficiency is high. And the machining efficiency of grinding machining of the valve element is reduced. A first electric telescopic rod is arranged on the outer wall of the middle of the top end of the bottom plate, a supporting plate is arranged at the output end of the first electric telescopic rod, a valve element to be machined is placed on the top of the supporting plate, and a rotating motor is arranged on the inner wall of one side of the top of the mounting frame. According to the utility model, the valve core is adaptively fixed according to the specification of the valve core,
