The caliper 3 includes a main scale 31 and a caliper 31 fixed at one end of the main scale 31. The fixed secondary scale 32, the dynamic secondary scale 34 moving along the main scale 31 through the sliding sleeve 33, and the spring 35 fixed between the fixed secondary scale 32 and the dynamic secondary scale 34, the main scale 31 and the sliding sleeve 33 are respectively provided with length scales, the main scale 31 is fixed to the housing of the resistor box 5, the top of the sliding sleeve 33 is fixed to the sliding piece of the sliding rheostat in the resistor box 5, the resistor box 5, the motor 7 and the display screen 8 are respectively electrically connected to the controller 9, and a plurality of the clamps 12 are arranged around the central axis of the turntable 11 The clamp 12 includes a first protrusion 122 fixed on the top surface of the turntable 11, a first bolt 121 screwed into the threaded hole of the first protrusion 122, and a block 123 fixed at the bottom end of the screw of the first bolt 121. The resistance box 5 is provided with a test circuit formed by connecting a power supply, a switch, an ammeter and a sliding rheostat in series. The support frame 4 is horizontally provided with a first cross bar 41 and a second cross bar 44 on the side close to the turntable 11. The resistance box 5 is slidably fixed on the first cross bar 41 and the second cross bar 44 by the sliders. In the sliding grooves on the bottom surfaces of the cross bars 41 and the second cross bars 44, second protrusions 43 and second bolts 42 screwed into the threaded holes of the second protrusions 43 are respectively provided on the bottom surfaces of the first cross bars 41 and the second cross bars 44 and on both sides of the resistance box 5. The upper and lower groups of calipers 3 of the measuring device are respectively fixed vertically and horizontally on the resistance box 5. The spring 35 in the caliper 3 on the upper side pushes the moving secondary scale 34 away from the fixed secondary scale 32, and the spring 35 in the caliper 3 on the lower side pulls the moving secondary scale 34 close to the fixed secondary scale 32.

[0017] Working process of the present invention:

[0018] First, insert the movable scale 34 and the fixed scale 32 of the caliper 3 located on the upper side into the central through hole of the bearing to be tested, then pull the movable scale 34 of the caliper 3 located on the lower side away from the fixed scale 32 to form a gap, pass the bearing to be tested through the gap, and then place the bearing to be tested between the blocks 123 of several clamps 12, rotate the first bolt 121, push the block 123 to move toward the center, and thus clamp the bearing to be tested. Next, rotate the second bolt 42 to push the resistance box 5 located on the upper side and the lower side to move along the slide grooves in the first cross bar 41 and the second cross bar 44 respectively, so that the movable scale 34 of the caliper 3 located on the upper side and the lower side respectively touches one side of the inner wall and the outer wall of the bearing to be tested. When the movable scale 34 and the fixed scale 32 of the caliper 3 are in contact, the resistance value of the sliding rheostat is 0, and the reading of the caliper 3 is 0. Due to the elastic force, the spring 35 of the caliper 3 on the upper side automatically pushes the moving scale 34 to move to the side away from the fixed scale 32 until the moving scale 34 hits the other side of the inner wall of the bearing to be tested, and the spring 35 of the caliper 3 on the lower side automatically pulls the moving scale 34 to move to the side close to the fixed scale 32 until the inner side of the moving scale 34 hits the other side of the outer wall of the bearing to be tested. In the process, the moving moving scale 34 drives the sliding piece to move, gradually changing the resistance value of the sliding rheostat box, thereby gradually changing the current value of the test circuit. The controller 9 reversely deduces the moving distance of the sliding piece through the obtained current value of the test circuit, thereby obtaining the inner and outer diameters of the bearing to be tested, and displays it on the display screen 8. The inner diameter of the bearing to be tested is the sum of the moving distance of the sliding piece of the sliding rheostat located on the upper side, the width of the moving scale 34 and the width of the fixed scale 32, and the outer diameter of the bearing to be tested is the moving distance of the sliding piece of the sliding rheostat located on the lower side. At the same time, the accuracy of the inner and outer diameter data of the bearing to be tested can be checked by the length scales on the main scale 31 and the sleeve 33. Next, the motor 7 drives the turntable 11 to rotate a certain angle, driving the bearing to be tested to rotate a certain angle, thereby testing the inner and outer diameters of the bearing to be tested at multiple points to obtain the average values ​​of the inner and outer diameters.

[0019] The present invention uses a spring to push or pull the movable secondary scale away from or close to the fixed secondary scale until the movable secondary scale and the fixed secondary scale located inside and outside the bearing to be detected respectively clamp the two ends of the inner wall or the outer wall, and uses the movable secondary scale to move a sliding piece with a sliding rheostat during the movement process to change the resistance value of the sliding rheostat, so as to reversely obtain the inner and outer diameters of the bearing to be detected through the current size; uses the movable secondary scale to drive the sliding sleeve to move along the main scale during the movement process, so as to obtain the inner and outer diameters of the bearing to be detected through the length scale, and judge the accuracy of the data; and uses a motor to drive the turntable to rotate a certain angle, so as to drive the bearing to be detected to rotate a certain angle, so as to realize multi-point measurement.
