Height-adjustable clamping device for mechanical automatic machining

Abstract

The utility model relates to the technical field of clamping devices, in particular to a height-adjustable mechanical automatic machining clamping device which comprises a clamping box, and the lower side of the clamping box is in threaded connection with a lifting mechanism. The clamping box comprises a clamping base, a clamping upper cover installed at the top end of the clamping base and a clamping mechanism installed in the clamping base. The lifting mechanism comprises a lifting base, a plurality of lifting motors installed at the four corners of the lower surface in the lifting base and a plurality of lifting threaded rods installed on output shafts of the lifting motors. In the utility model, if machining cutters with different lengths are replaced during machining, the height of the cutter can be directly adjusted by using the lifting mechanism according to the change of the length of the cutter, so that the distance between the lower end of the cutter and the upper end of a part is ensured to be unchanged; and it is ensured that the clamped part can be located in the middle of the upper surface of the clamping upper cover, and machining is convenient.
