specific Embodiment approach 1
[0050] The following embodiment is an embodiment of a circularity error separation device based on synchronous motion in the present invention.
[0051] A synchronous movement-based roundness error separation device in this embodiment, the structural diagram is as follows figure 1 shown. The circularity error separation device based on synchronous motion includes a transverse guide rail 1, a displacement sensor 2, an error separation turntable 4, a rotary table 5 and a vertical guide rail 6, the displacement sensor 2 moves horizontally on the transverse guide rail 1, and the transverse guide rail 1 Drive the displacement sensor 2 to move up and down along the vertical guide rail 6, the error separation turntable 4 is placed flat on the rotary table 5, the error separation turntable 4 rotates together with the tested part 3, and the rotary table 5 drives the error separation turntable 4 and the tested part 3 coaxial rotation.
[0052] The rotary table 5 is in the form of hydr...
specific Embodiment approach 2
[0055] The following embodiment is an embodiment of a circularity error separation method based on synchronous motion in the present invention.
[0056] A method for separating roundness errors based on synchronous motion of the present invention comprises the following steps:
[0057] Step a, place the error separation turntable 4 on the rotary table 5, and roughly adjust the error separation turntable 4 to be concentric with the rotary table 5;
[0058] Step b, determine the section to be measured of the tested piece 3, adjust the height of the horizontal guide rail 1 and the displacement sensor 2 along the vertical guide rail 6, so that the section to be measured of the tested piece 3 and the measuring head of the displacement sensor 2 are on the same section, adjust DUT 3, making the section to be measured of DUT 3 concentric with error separation turntable 4;
[0059] Step c, regard the error separation turntable 4 and the measured piece 3 as a whole, and adjust the erro...
