Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and more specifically, particularly relates to a processing fixture for a numerical control machine tool. Background Art

[0002] CNC machine tools process parts through system control. When workers use CNC machine tools to process parts, they need to place the raw materials of the parts on the machine tool. The processing fixtures on the machine tool clamp the raw materials of the parts and fix them. Then the raw materials of the parts are processed into finished parts through the processing components on the machine tool.

[0003] For example, the utility model with application number 202222974883.9 discloses a CNC machine tool processing fixture, which belongs to the field of mechanical processing technology, including a base, a fixed clamping plate fixedly connected to the upper end of the base, a motor is provided on one side of the fixed clamping plate, a threaded column is fixedly connected to the output end of the motor, the other end of the threaded column is rotatably connected to the side wall of the fixed clamping plate, and limit bars are provided on both sides of the threaded column, the limit bars are fixedly connected to the upper end of the base, the two limit bars are arranged parallel to the threaded column, a movable clamping plate is slidably arranged between the two limit bars, a threaded hole is provided on the movable clamping plate, the threaded column is threadedly connected in the threaded hole, a first buffer pad is fixedly connected to the side wall of the movable clamping plate close to the motor, and a roller is fixedly installed on the lower end of the movable clamping plate. The utility model effectively protects the movable clamping plate from wear and tear, and achieves the purpose of extending the service life of the CNC machine tool.

[0004] Based on the above, the existing processing fixtures generally fix the part raw materials through the clamping block sliding structure. When the part raw materials are installed on the machine tool, the staff needs to place the part raw materials on the machine tool first, and then operate the clamping block to slide to clamp and fix the part raw materials. After the processing is completed, the staff operates the clamping block to slide to release the part, and then the staff lifts the part and puts it into the inbox. The operation is relatively cumbersome. Utility Model Content
