Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a workpiece fixing component for a numerically controlled machine tool. Background Art

[0002] CNC machine tools have better solved the problems of complex, precise, small-batch, and multi-variety parts processing. They are flexible, high-efficiency automated machine tools, represent the development direction of modern machine tool control technology, and are typical mechatronics products. When processing shaft products, CNC machine tools often need to be locked through fixtures. Chuck-type fixtures are a common machine tool accessory, which mainly utilizes the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. Among them, the three-jaw chuck is the most common. The three-jaw chuck is characterized by automatic centering and strong clamping force.

[0003] The patent document with the published announcement number CN 220407945 U discloses a workpiece fixing device for a CNC machine tool, comprising a base, a push block is arranged on the top of the base, the top of the base is fixedly connected to a first fixing block, and a fixing mechanism is arranged on the opposite side of the first fixing block and the push block; the fixing mechanism comprises a first fixing plate, a first bolt and a second fixing plate, the left side of the left first fixing plate is fixedly connected to the right side of the push block, and the right side of the first fixing plate is fixedly connected to the left side of the first fixing block, and the first bolt is arranged on the top of the first fixing plate, which solves the problem that most of the existing workpiece fixing devices used in CNC machine tools can only fix specific workpieces when fixing and processing the workpieces, and when fixing different workpieces, the CNC machine tool needs to be disassembled and replaced with a suitable fixing structure, and the disassembly process is relatively cumbersome and inconvenient to disassemble.

[0004] The above devices are not effective in clamping and fixing, and do not collect the debris generated when the machine tool is working, which can reduce the impact of the debris on the staff. Therefore, a workpiece fixing component for a CNC machine tool is needed. Utility Model Content
