[0002] Four-axis fixtures are often installed on CNC machine tools and are mainly used for multi-sided processing of products. When using a four-axis fixture, the corresponding clamping blocks need to be installed on the base, and then the clamping blocks need to be adjusted. When processing annular workpieces, cylindrical workpieces, and workpieces with circular bottom spaces, staff need to control the device to fix workpieces of different sizes. In this process, the fixing components are often fixed to the outer wall of the workpiece. Therefore, when processing the workpiece, the fixing components are easy to block the outer wall of the workpiece, making it impossible to fully process the outer wall of the workpiece, resulting in the produced workpiece failing to meet the use standards. Therefore, in view of the current situation, it is now necessary to improve it. Utility Model Content

When the fixing rings 202 on both sides cannot fit with the inner wall of the bottom of the workpiece, the fixing bolts 208 on both sides can be removed and the fixing rings 202 that match the inner wall of the bottom of the workpiece to be processed can be replaced, so that different workpieces can be fixed.

[0026] The outer walls of the fixing rings 202 on both sides are fixedly connected with anti-slip pads, so that the workpiece can be fixed more firmly.

This will cause a situation where normal processing cannot be performed. When the fixing rings 202 on both sides cannot fit with the inner wall of the bottom of the workpiece, the fixing bolts 208 on both sides can be removed and replaced with fixing rings 202 that match the inner wall of the bottom of the workpiece to be processed. Different workpieces can be fixed. After the workpiece is fixed, the first gear 302 is rotated by starting the motor 300, wherein the first gear 302 is in a meshing relationship with the second gears 303 on both sides. As the motor 300 works, the mounting seats 200 on both sides can be rotated, thereby rotating the workpieces fixed on both sides, making it easier to process the workpiece.
