Vice

Abstract

The invention provides a vice which is used for clamping a workpiece. The vice is characterized by comprising a clamping assembly used for clamping the workpiece, and a base assembly used for installing the clamping assembly and driving the clamping assembly to rotate, wherein the clamping assembly comprises guide rails capable of being rotationally fixed to the base assembly, a first vice body, a second vice body, a spiral mechanism and a crank slider mechanism, the first vice body and the second vice body are installed on the guide rails and move back and forth along the guide rails, the spiral mechanism is installed at one end of the guide rails and abuts against the first vice body through rotation so as to make the first vice body move along the guide rails, the slider crank mechanism is installed at the other end of the guide rails and connected with the second vice body, and the second vice body is driven to move by the crank slider mechanism through a crank slider; the base assembly comprises a worm and gear mechanism used for installing the guide rails and driving the guide rails to rotate, and a base used for installing the worm and gear mechanism.

Description

technical field [0001] The invention relates to a clamp, in particular to a vise that can be fastened and loosened and the clamping direction can be adjusted. Background technique [0002] A vise is a device used to clamp and position a workpiece. Most of the traditional vises are fixed at one end of the clamp body, and the other end is driven by a rotating screw to move the movable clamp body to clamp the workpiece. It takes a long time to clamp the workpiece by rotating the screw rod, resulting in very low work efficiency. Low. [0003] The patent application No. 201110150247.8 discloses a fast bench vise, which is driven by a rack and pinion. Compared with the above-mentioned vise, the time required for clamping the workpiece is shortened, but the rack and pinion of this vise The mechanism itself cannot achieve self-locking, and an additional locking device needs to be added to make its structure very complicated; in addition, this vise can only clamp the workpiece in o...
