Embodiment Construction
[0040] A preferred example of the present invention is described in detail as follows in conjunction with accompanying drawing:
[0041] The method for measuring the roundness error of the roll and the error of the machine tool spindle in the diameter and parallel multi-position adopts the measuring device shown in Fig. , 7 and 10 drives, the ball screw pair 8 needs to set the critical position as the boundary line of the ball screw pair 9, so as to avoid collision with the ball screw pair 9 during the measurement process. The measuring heads of the two sensors 1 and 2 and the measuring head of the sensor 3 parallel to the sensor 2 are installed on the measuring arms 15, 11 and 16 respectively, and driven by the ball screw pairs 5, 8 and 9 respectively. come to contact the roll 13 on the central support 14, thereby realizing the measurement of rolls with different diameters. The sensor measuring heads 1 and 2 should be located on the center line of the roll 13, and the angle ...
