Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and more specifically, the utility model relates to a numerical control machine tool fixture that is easy to disassemble. Background Art

[0002] A numerical control machine tool is an automated machine tool equipped with a program control system. During the machining process of a numerical control machine tool, fixtures are usually required to position workpieces. Special tools are needed during the installation process, which is rather cumbersome. In order to match different fixtures, the fixture clamps need to be frequently disassembled and assembled, bringing certain troubles to the disassembly and assembly process of workers. Therefore, a fixture that is easy to disassemble needs to be designed. For example, a numerical control machine tool fixture disclosed in the patent with the publication number CN221270320U in the prior art places the workpiece to be machined above the workbench of the numerical control machine tool, so that the workpiece is located in the middle of two U-shaped chucks. Then, the driving motor is started to drive the movable nut to move towards each other on the double-sided threaded rod. The movable nut drives the special-shaped support plate to move towards the middle, so that the left and right ends of the workpiece are located inside the U-shaped chucks, limiting the workpiece to be machined. The first hydraulic cylinder works to push the positioning plate into full contact with the workpiece, clamping and fixing the workpiece, so that the workpiece is firmly assembled above the workbench of the numerical control machine tool, and then machining operations can be carried out on it.

[0003] When the above device is in use, the U-shaped chucks can be quickly installed and disassembled, which is convenient for workers to carry out maintenance operations on it. At the same time, U-shaped chucks of different specifications can be replaced according to processing requirements, improving the flexibility and practicality of the workbench of the numerical control machine tool. However, when clamping and machining the workpiece, the surface of the workpiece will be subjected to external forces, and the second hydraulic cylinder and the first hydraulic cylinder are easily affected and damaged, thus affecting the convenience of disassembling the clamping fixture of the numerical control machine tool, and at the same time, it is also easy to affect the stability of its clamping work.
