Description

Tool clamp for machining Technical Field The utility model relates to the technical field of bag-type dust removing equipment, in particular to a tool clamp for machining. Background A machining fixture, also called a machining positioning device, is a device used for fixing a machining object in a machining process so as to occupy a correct position for construction or detection. In a broad sense, any process in the process, the means for quickly, conveniently and safely installing a product may be referred to as a machining fixture. In the prior art, a workpiece is fixed by using a special workpiece clamp when the workpiece is required to be punched, so that the workpiece is prevented from moving outwards when the workpiece is punched, but the existing clamp is inconvenient to rapidly position the workpiece and rapidly replace different drilling sleeves. Therefore, the utility model provides a tool clamp for machining, which is used for solving the problems. Disclosure of utility model The utility model aims to provide a tool clamp for machining, which solves the problems in the background technology.
