The working process of the invention is as follows:
firstly, the movable auxiliary scale 34 and the fixed auxiliary scale 32 of the caliper 3 positioned on the upper side are inserted into a central through hole of a bearing to be detected, then the movable auxiliary scale 34 of the caliper 3 positioned on the lower side is pulled to be away from the fixed auxiliary scale 32 to form a gap, the bearing to be detected penetrates through the gap, then the bearing to be detected is placed between the clamping blocks 123 of the plurality of clamping devices 12, the first bolt 121 is rotated to push the clamping blocks 123 to move towards the center, and therefore the bearing to be detected is clamped. Then, the second bolt 42 is rotated to push the resistance boxes 5 located at the upper side and the lower side to move along the sliding grooves in the first cross rod 41 and the second cross rod 44, respectively, so that the movable auxiliary ruler 34 of the caliper 3 located at the upper side and the lower side respectively abuts against one side of the inner wall and the outer wall of the bearing to be detected. When the movable sub-scale 34 of the caliper 3 and the fixed sub-scale 32 are in contact, the resistance value of the slide rheostat is 0, and the reading of the caliper 3 is 0. The spring 35 of the caliper 3 located at the upper side automatically pushes the movable auxiliary scale 34 to move towards one side far away from the fixed auxiliary scale 32 due to the elastic force until the movable auxiliary scale 34 butts against the other side of the inner wall of the bearing to be detected, and the spring 35 of the caliper 3 located at the lower side automatically pulls the movable auxiliary scale 34 to move towards one side close to the fixed auxiliary scale 32 due to the elastic force until the inner side of the movable auxiliary scale 34 butts against the other side of the outer wall of the bearing to be detected. In the process, the moving auxiliary ruler 34 drives the sliding sheet to move, so that the resistance value of the sliding resistance-variable box is gradually changed, and the current value of the test circuit is gradually changed. The controller 9 reversely pushes the moving distance of the slide sheet according to the obtained current value of the test circuit, so that the inner diameter and the outer diameter of the bearing to be detected are obtained and displayed on the display screen 8. The inner diameter of the bearing to be detected is the sum of the moving distance of the slide sheet of the slide rheostat positioned at the upper side, the width of the movable auxiliary ruler 34 and the width of the fixed auxiliary ruler 32, and the outer diameter of the bearing to be detected is the moving distance of the slide sheet of the slide rheostat positioned at the lower side. Meanwhile, the accuracy of the obtained data of the inner diameter and the outer diameter of the bearing to be detected can be checked through the length scales on the main scale 31 and the sliding sleeve 33. Next, the motor 7 drives the turntable 11 to rotate by a certain angle to drive the bearing to be detected to rotate by a certain angle, so that the inner diameter and the outer diameter of the bearing to be detected are tested at multiple points to obtain the average value of the inner diameter and the outer diameter.
The movable auxiliary ruler is pushed or pulled to be far away from or close to the fixed auxiliary ruler through the spring until the movable auxiliary ruler and the fixed auxiliary ruler which are positioned inside and outside the bearing to be detected are respectively clamped at two ends of the inner wall or the outer wall, and the resistance value of the slide rheostat is changed by utilizing the movement of the slide sheet with the slide rheostat in the moving process of the movable auxiliary ruler, so that the inner diameter and the outer diameter of the bearing to be detected are obtained through the reverse thrust of the current; the movable auxiliary ruler is utilized to drive the sliding sleeve to move along the main ruler in the moving process, so that the inner diameter and the outer diameter of the bearing to be detected are obtained through the length scale, and the accuracy of data is judged; the motor drives the turntable to rotate by a certain angle, so that the bearing to be detected is driven to rotate by a certain angle, and multi-point measurement is realized.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
