[0002] The frame of a high-precision inertial element liquid-floating gyroscope is characterized by high machining precision and complex structure. The frame itself contains numerous holes and wire grooves, and many enameled wires come into physical contact with these holes and wire grooves. Failure to remove burrs around these holes and wire grooves can lead to quality problems. Burrs on the frame wire grooves can cut the leads, causing short circuits. Furthermore, during the gyroscope's high-speed operation, vibrations can cause burrs on the frame to fall off, causing the gyroscope to become stuck or damaged.

[0003] The burrs on the holes or wire grooves of the frame can be removed by high-speed abrasive flow deburring technology. The working medium of high-speed abrasive flow deburring technology is an aqueous solution with fine suspended abrasive particles. The aqueous solution is placed in the holes or wire grooves of the frame through a nozzle to remove the burrs. High-speed abrasive flow deburring technology is a flexible processing method that causes less damage to the frame. However, there is currently no clamping device that matches the frame for processing and removing burrs on the holes or wire grooves of the frame.

[0004] In order to solve the above technical problems, a clamping device suitable for high-speed abrasive flow machining of gyroscope frames is provided. Summary of the Invention
