Description

Automatic fixture of machine tool for pneumatic chip removal Technical Field The invention relates to the technical field of fixtures of machine tools, in particular to an automatic fixture of a machine tool for pneumatically clearing scraps. Background The numerical control machine tool is short for numerical control machine tool, and is an automatic machine tool with a program control system. The control system is able to logically process a program defined by control codes or other symbolic instructions, and to decode it, expressed in coded numbers, and input to the numerical control device via the information carrier. The numerical control device sends out various control signals to control the action of the machine tool through operation processing, and parts are automatically machined according to the shape and the size required by the drawing. Numerical control machine tools generally adopt a fixture to fix parts for processing, and the positioning accuracy of the fixture influences the precision of part processing to a certain extent. In the prior art, after the part is generally positioned and fixed through a fixture, the part is reduced in material through a processing cutter, and the temperature is reduced due to the high temperature in the processing process, so that the cutter is prevented from being high Wen Shousun. In the machining process, machining scraps of the material reduction can fall down, and the machining scraps are doped in the parts of the cooling liquid scattering fixture, so that after a part is machined, the scraps are generally purged through a purging device to locate the next machined part, but due to the fact that the cooling liquid exists, part of the scraps after purging exists in the current purging means are retained, and therefore, when the part is located again, a small deviation occurs in locating, the deviation is small, the machining precision is possibly not affected, but the situation that the machining precision is affected partially also occurs is caused, and therefore, based on the problem, a new machine tool fixture is needed.
