Tool clamp for testing flat wire motor stator copper wire welding spots

A tool clamp used for testing flat wire motor stator copper wire welding spots comprises a base, the lower side of the base is connected with a tensile testing machine lower connecting piece, a fixing base is arranged on the base, the front side face of the fixing base is provided with an installation groove, the installation groove penetrates through the top face and the bottom face of the fixing base in the vertical direction, and the fixing base is provided with a clamping groove. A profiling block is detachably connected to the front side of the fixing base, a profiling groove is formed in the rear side face of the profiling block and is in a long strip shape, the bottom of the profiling groove downwards penetrates through the bottom face of the profiling block, and the profiling groove is located on the front side of the mounting groove. In the shearing test, the stress direction of the welding spot is similar to the actual working condition, and the test result is accurate. A clamping part of the sheari
