The utility model discloses a concentric positioning installation device, which comprises a frame, a
synchronizing wheel, a guide block and an output part, the frame is a cylindrical shell and comprises a
peripheral surface, an upper end surface and a base, and a test piece is arranged between the upper end surface and the base and is coaxial with the frame; the
synchronizing wheel is rotationally installed on the upper end face and coaxial with the frame, two or more sets of
synchronizing connecting rods are arranged on the synchronizing wheel and evenly distributed, and the symmetric centers of the synchronizing connecting rods are located on the axis of the synchronizing wheel; the more than two guide blocks are in one-to-one correspondence with the synchronous connecting rods, are fixedly arranged at the end parts of the synchronous connecting rods and are positioned on the inner side of the
peripheral surface, and the symmetric centers are positioned on the
central line of the frame; the output parts are in one-to-one correspondence with the guide blocks and penetrate through the
peripheral surface and the guide blocks at the same time, the radial output positions of the output parts are determined, the output ends of the output parts are connected with positioning pins, and the positioning pins are driven by the output parts to be synchronously adhered to the test piece. The device realizes concentric positioning, and improves the
simulation accuracy of the test process.
