Multi-stage gear blank coaxiality detection device

Abstract

The utility model discloses a multi-stage gear blank coaxiality detection device, which relates to the technical field of gear blank detection equipment and comprises a base, and a three-coordinate measuring machine is mounted at the top end of the base. A motor is installed at the bottom end of the interior of the base, the output end of the motor is connected with a worm, and the bottom end of the interior of the base is rotationally connected with a rotating rod. According to the utility model, the plurality of fixing pipes are annularly arranged at the top end of the turntable at equal intervals, so that the gear blanks can be sleeved on the surface of the turntable and fixed, a plurality of gear blanks can be simultaneously mounted, the rotating rod can drive the turntable and the gear blanks to rotate through the work of the motor and the like, and the rapid switching detection of the gear blanks can be realized; long waiting time caused by frequent disassembly and assembly is avoided, gear blanks on the surfaces of the fixing pipes at different positions sequentially enter the working range of the three-coordinate measuring machine through rotation of the rotating disc, assembly line type testing is achieved, and the testing amount in unit time is remarkably increased.
