Description

Technical Field

[0002] In the production process of asynchronous motors, aluminum castings are one of the important parts of the motor. During the manufacturing process of aluminum castings, the aluminum castings need to be processed, transported and positioned. When positioning the aluminum castings, a clamping device is needed to fix the aluminum castings, so as to facilitate the processing of the aluminum castings.
