Abstract

The invention discloses a device for measuring peeling force of a welded nut and a welded bolt. The device comprises two parallel supporting frames, a top plate arranged between the tops of the two parallel supporting frames, a spring arranged on the inner side of the top plate, a sliding block arranged at the end of the spring, a jack arranged between the top plate on one side of the spring and the sliding block, an S-shaped external sensor arranged at the bottom of the sliding block, a detection block arranged on the S-shaped external sensor, a lifting workbench arranged below the detection block and located between the two parallel supporting frames, a dynamometer connected with the S-shaped external sensor, arranged on the top plate, and a detection workpiece arranged between the detection block and the lifting workbench. The device has the effects of rapid pressure detection, guarantee of production efficiency, small size and convenience in operation.

Description

technical field [0001] The invention relates to the field of automobile sheet metal welding measuring equipment, in particular to a measuring device for the stripping force of welding nuts and bolts. Background technique [0002] In the automotive sheet metal welding industry, the welding strength of nuts and bolts needs regular monitoring and rapid measurement. One of the methods for measuring the welding strength of nuts and bolts is the detection of peeling force. At present, the known peel force testing equipment mainly adopts universal testing machine, which is expensive and needs to be tested by full-time testing personnel. In addition, it is large and must be stored in the laboratory. untimely phenomenon. In addition, the pressure detection range needs to be 0-20KN, while the maximum detection range of the portable desktop dynamometer on the market is 1KN, which cannot meet the measurement requirements. Welding strength is very important in the field of automobile m...
