Description

Technical Field

[0001] The utility model relates to the field of numerical control machine tools, in particular to a fixture fixing device for numerical control machine tools which is easy to disassemble and assemble. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. It can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. The information is input into the CNC device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically processes the parts according to the shape and size required by the drawing. However, some of the devices need to fix the workpiece in the fixture in advance before operation, and the fixture cannot adjust the distance between the clamping blocks. It can only be used for clamping and processing of the same type of workpiece, which is not conducive to the multi-effect and multi-functional use of CNC machine tools. In the existing technology, the adjustment performance of most fixtures is relatively single, which makes it difficult to process the workpiece during the use of the fixture.
