by:Tronshal     2022-02-26
The simple detection device for the elastic index of the wave washer is composed of a weight, a base, a screw, a foot, a dial indicator and a concave groove. The base is in the shape of a disc, the weights are placed in the upward-facing disc cavity, the middle of the disc cavity is provided with an axial through hole to install the dial indicator rod, the screw locks the dial indicator rod, and the lower end surface of the base is from the bottom to the bottom. Foot support. The utility model is provided with a concave groove with an axial through hole in the middle of the ring on the end face of the disk cavity with the base facing upward, and the concave groove is matched with the bottom of the wave washer to be inspected. When testing, the wave washer to be tested is positioned with a concave groove. Before the wave washer is placed, first set the bottom end face of the weight in the axial through hole as the zero position of the dial indicator, and the placed wave washer is positioned with the concave groove. After adding the weight, the deformation of the wave crest makes the head of the dial indicator shrink inward, and the inward shrinking size is the measured elastic index value. The utility model loads the weight vertically under the positioning condition, the force is uniform, the elastic deformation is real, the measurement result is accurate, and the detection operation is convenient.
