[0076] How it works

[0077] In the initial state, the two rectangular blocks 203 are in contact with the inner walls of the two sides of the rectangular groove respectively, and the two hydraulic rods 601 are in the maximum extension state. When detecting the depth of the groove 500 on the shaft part 300, first, the shaft part 300 is placed in the middle of the two rectangular blocks 203, and the second motor 202 is started to drive the bidirectional screw 201 to rotate. The rotation of the bidirectional screw 201 drives the two rectangular blocks 203 to move toward the middle at the same time, so that the shaft part 300 is effectively horizontally clamped and fixed on the two arc plates 204 in the middle of the two rectangular blocks 203, so as to achieve the purpose of effectively fixing the shaft part 300 during detection, and ensure that the shaft part 300 is fixed when the depth of the groove 500 is detected. The stability of the part 300 ensures the convenience and accuracy of the detection; thereafter, after the shaft part 300 is fixed, the two hydraulic rods 601 are started to shrink, driving the rectangular frame 602 and the base 401 to move downward, so that the arc surface of the lower surface of the base 401 can be tightly attached to the outer surface of the shaft part 300, so that the extension rod 403 on the micrometer 402 enters the groove 500 and contacts the bottom wall of the groove 500. At this time, the micrometer 402 is calibrated to zero, and then the first motor 605 is started again to drive the threaded column 606 to rotate. The rotation of the threaded column 606 drives the slider 603 to move. The movement of the slider 603 drives the base 401 on the shaft through the L-shaped rod 604. The surface of the part 300 moves slowly, thereby driving the extension rod 403 to move slowly on the inner wall of the groove 500. During the movement of the extension rod 403, the reading of the dial gauge 402 is observed. The difference between the maximum and minimum readings of the dial gauge 402 is the depth difference of the groove 500, so that the device can automatically detect the depth of the groove 500. Moreover, when the first motor 605 drives the meter base 401 to automatically move and detect the surface of the shaft part 300, when the L-shaped rod 604 moves with the slider 603, it can drive the connecting shaft 707 to rotate under the action of the two straight tooth grooves 709, and the rotation of the connecting shaft 707 is controlled by the two third bevel gears 70 10 drives the vertical rod 704 to rotate, the rotation of the vertical rod 704 drives the cross bar 703 to rotate under the action of the two second bevel gears 706, the rotation of the cross bar 703 drives the rotating shaft 701 to rotate under the action of the two first bevel gears 705, the rotation of the rotating shaft 701 drives the steel wire ball 702 to rotate on the inner wall of the groove 500, thereby effectively grinding and cleaning the inner wall of the groove 500, and at the same time, during the movement of the table base 401, it can drive the elastic sponge pad 7011 to move on the inner wall of the groove 500, wipe and clean the debris and debris generated by grinding, thereby achieving the purpose of automatically cleaning the groove 500 during the detection process, thereby effectively ensuring the accuracy of the detection.
