Motor shell clamp

The invention belongs to the technical field of clamps, and provides a motor shell clamp. The motor shell clamp comprises a mounting base, a supporting assembly, a positioning assembly and a clampingassembly; the supporting assembly is movably arranged on the mounting base and is used for bearing and driving a motor shell to transversely move, the positioning assembly is arranged on the mountingbase and located on the side of the supporting assembly, when the supporting assembly moves towards the direction of the positioning assembly, the end of the motor shell can be driven to abut againstthe positioning assembly, the clamping assembly is movably arranged on the mounting base and located on the side, away from the positioning assembly, of the supporting assembly, and one end of the clamping assembly abuts against the end of the motor shell and drives the other end of the motor shell to tightly abut against the positioning assembly. Compared with the prior art, the clamp has the advantages that the motor shel
