Abstract
The utility model discloses a device for measuring concentricity of a ring groove and an outer circle of a piston. The device includes a mandrel, a dial indicator and a positioning gauge rack. A piston is movable mounted on the mandrel. The dial indicator is mounted above the piston. The positioning gauge rack is a bent structure with one end connected with a lower end portion of the dial indicator and the other end disposed on a side of the mandrel. The piston can rotate in the mandrel in an angle range of 0 to 360 degrees. According to the device for measuring the concentricity of the ring groove and the outer circle of the piston, the piston rotates in the mandrel in an angle range of 0 to 360 degrees, and the data read after the piston is rotated by 360 degrees is the concentricity of the ring groove and the outer circle of the piston, and thus the operation of the device is simple and convenient. The device helps to improve work efficiency and reduce investment of human resources. Meanwhile, a detection precision error can be minimized, a product pass rate can be improved, and the operation cost can be reduced.
