Cam compression clamp

Abstract

The invention discloses a cam compression clamp and aims to solve the problem that a boss horizontally extending out on a workpiece cannot be well fixed in the prior art. According to the scheme disclosed by the invention, the cam compression clamp comprises an engine bed, a fixed supporting part, a clamping jaw, a cam and a guide rod, wherein the fixed supporting part is used for lifting up the workpiece; the clamping jaw is used for compressing the upper surface of the workpiece; the cam is located below the clamping jaw and serves as a force application device; the guide rod is connected onto the clamp body; the clamping jaw has a freedom of vertical motion under the restraint of the guide rod; a reset spring is also arranged between the clamping jaw and the guide rod; the clamping jaw comprises an upper driven end and a lower driving end, wherein the upper driven end plays a clamping role, and the lower driving end plays a force application role. The cam compression clamp is characterized in that the cam is abutted with the lower driving end, and the geometric center of a clamping part of the upper driven end and the geometric center of the part, contacted with the cam, of the lower driving end are located on the same plumb line. The technical scheme disclosed by the invention has the characteristic that the boss horizontally extending out on the workpiece can be well fixed.

Description

technical field [0001] The invention relates to a clamp. Background technique [0002] Machine tool fixtures are indispensable and important process equipment in the machinery manufacturing industry, which can ensure the quality of machining, improve production efficiency, reduce production costs, and reduce labor intensity.
