[0034] The clamping assembly includes two fixed plates 11, both of which are fixedly connected to the top of the placing plate 5. One side of one of the fixed plates 11 is fixedly installed with an electric push rod 12, and the telescopic end of the electric push rod 12 is fixedly connected with a clamping plate 13. The setting of the clamping assembly enables the sheet metal part to be clamped and fixed, preventing it from moving during processing.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
