[0002] A grinder fixture is a device used to hold and secure a workpiece for precision grinding and machining operations on a grinding machine. The main purpose of a grinder fixture is to ensure that the workpiece remains stable during the grinding process to achieve the required accuracy and surface quality. These fixtures can be of various designs and mechanisms to accommodate different shapes, sizes and types of workpieces.

[0003] After searching, a Chinese patent discloses a grinding machine fixture with a publication number of CN217371940U, which includes a flat base plate, a clamping hole for the grinding machine fixing fixture is arranged in the center of the base plate, and two first fixing pins and two second fixing pins are arranged on the upper plate surface of the base plate. The two first fixing pins are arranged side by side and arranged at the edge of the base plate, and the two second fixing pins are arranged side by side. The two second fixing pins are connected by a connecting part, and a plug hole is arranged on the connecting part, and a limit pin is detachably inserted into the plug hole. Although this patented technology can clamp and fix the workpiece, the clamping stability is strong, which is convenient for subsequent grinding machine processing, but after the workpiece is clamped and fixed, the workpiece can only remain in a motionless state. When the workpiece needs to be processed in different directions or angles, it cannot be automatically adjusted. It can only be clamped at a different angle by adjusting the angle of the processing equipment or taking the workpiece off, which results in more time and effort during processing, which reduces work efficiency.

[0022] 1. In the utility model, through the combination of structures such as a workbench, a support frame, a mounting shell, an offset rod, a fixed frame, an electric push rod, a sliding frame, a motor, a clamping mechanism, a ring plate 1, a ring plate 2, a ring groove 1, and a ring groove 2, it is possible to automatically adjust the angle of the workpiece after the workpiece is clamped and fixed, and can cooperate with processing equipment to process the workpiece efficiently and accurately, eliminating the time for secondary clamping, saving time and effort, and improving work efficiency.

[0023] 2. In the utility model, the clamping head can be replaced by combining structures such as the clamping frame, the clamping head, the outer shell, the clamping rod, the rotating rod, the slider, the spring, the support rod, etc. After the clamping head is worn and damaged due to long-term use, only the clamping head needs to be replaced, and there is no need to replace a whole set of clamping mechanisms.
