[0028] As shown in the accompanying Figure 1 , the accompanying Figure 3 and the accompanying Figure 4 , the roundness measurement part is arranged in the stepped hole on the left side of the fixed base 1, and the specific structure is as follows:

[0029] The roundness measurement part mainly includes a roundness measurement base 2 rotatably arranged in the stepped hole, a fixed disc 3 is coaxially fixed in the middle of the roundness measurement base 2, the fixed disc 3 is stepped, the upper end of the fixed disc 3 is fixedly connected with the roundness measurement base 2 through bolts, and the lower end penetrates the roundness measurement base 2 and is flush with the lower surface of the fixed base 1, so that the outer circle of the lower end of the fixed disc 3 contacts with the inner wall of the lower end hole of the stepped hole of the fixed base 1, and the outer circle of the roundness measurement base 2 contacts with the inner wall of the upper end hole of the stepped hole of the fixed base 1, so that no shaking occurs during rotation, and the accuracy of the measurement result is increased.

[0030] A circular angle scale turntable 4 is coaxially arranged on the roundness measuring base 2, a stop ring 5 is arranged on the inner circle of the circular angle scale turntable 4, the inner wall of the stop ring 5 should be in contact with the outer circle of the fixed disc 3, so that the circular angle scale turntable 4 does not shake during rotation and always guarantees coaxiality.
