The application relates to the technical field of connectors, in particular to a
welding cup plane trimming device. The
welding cup plane trimming device comprises a base, a
cutting assembly, a clamping mechanism and a pushing
assembly. The
cutting assembly is arranged at one end of the base and used for trimming a
welding cup. The clamping mechanism is arranged on the pushing assembly and used for clamping the welding cup. The pushing assembly is arranged at the other end of the base and opposite to the
cutting assembly, and is used for pushing the clamping mechanism to move the welding cup to the cutting assembly. The application can improve the
processing efficiency, the
processing precision and the flexible applicability of the welding cup plane.
