[0017] A first bidirectional screw rod 2 is rotatably arranged between the two fixed plates 11, and a symmetrically distributed first positioning block 21 is threadedly arranged on the first bidirectional screw rod 2. The first positioning block 21 is fixedly arranged on the lower surface of the first sliding block 13; by rotating the first bidirectional screw rod 2, the positions of the two first positioning blocks 21 can be brought closer or farther away.

[0018] A first motor 22 is fixedly disposed on one side fixing plate 11 , and an end of an output shaft of the first motor 22 is fixedly disposed on one end of the first bidirectional screw rod 2 ; the first bidirectional screw rod 2 can be driven by the first motor 22 .

[0019] A second bidirectional screw 23 is rotatably arranged between the two fixed plates 11, and a symmetrically distributed second positioning block 24 is threadedly arranged on the second bidirectional screw 23. The second positioning block 24 is fixedly arranged on the lower surface of the second sliding block 15; by rotating the second bidirectional screw 23, the positions of the two second positioning blocks 24 can be moved closer or farther away.

[0020] A second motor 25 is fixedly disposed on the fixing plate 11 away from one end of the first motor 22 , and an end of an output shaft of the second motor 25 is fixedly disposed on one end of the second bidirectional screw rod 23 ; the second motor 25 can drive the second bidirectional screw rod 23 .

[0021] A symmetrically distributed first fixed block 26 is fixedly provided on the upper surface of the base 1, a symmetrically distributed spring 27 is fixedly provided on one end of the first fixed block 26 close to the slide groove 12, a second fixed block 28 is fixedly provided on one end of the two springs 27 away from the first fixed block 26, and a limiting block 29 is fixedly provided on one end of the second fixed block 28 away from the spring 27; the bearing can be limited by the first fixed block 26, the spring 27, the second fixed block 28 and the limiting block 29.

[0022] The first scale plate 3 is fixedly arranged on the measuring plate 16 near the first motor 22 , and the end of the first scale plate 3 away from the first motor 22 is penetrated and arranged on the measuring plate 16 near the second motor 25 ; the staff can observe the value of the outer diameter of the bearing through the first scale plate 3 .

[0023] A second scale plate 31 is fixedly arranged on the first positioning block 21 near the first motor 22 , and one end of the second scale plate 31 is passed through the first positioning block 21 near the second motor 25 ; the staff can observe the value of the inner diameter of the bearing through the second scale plate 31 .

[0024] Working principle: When in use, the staff first needs to move the second fixed block 28 on one side to the closer first fixed block 26. As the spring 27 between the first fixed block 26 and the second fixed block 28 is deformed, the second fixed block 28 will move in the direction of the first fixed block 26. At this time, the staff can place the bearing to be measured between the two limit blocks 29. With the spring 27, the two limit blocks 29 will position the bearing. Then the staff can start the device. As the first motor 22 runs, it will drive the first bidirectional screw 2 to rotate. Since the first bidirectional screw 2 is threaded with symmetrically distributed first positioning blocks 21, the first positioning blocks 21 are fixedly arranged on the lower surface of the first slider 12, and the upper surface of the first slider 12 is fixedly arranged with a measuring column 14, when the first bidirectional screw 2 rotates, it will drive the position between the two measuring columns 14 to gradually move away. When the two measuring columns 14 are farthest away from each other and touch the inner wall of the bearing, they stop moving. At this time, the staff can obtain the value of the inner diameter of the bearing by observing the first scale plate 3.

[0025] As the second motor 25 runs, the second bidirectional screw 23 will be driven to rotate. Since the second bidirectional screw 23 is threaded with symmetrically distributed second positioning blocks 24, the second positioning blocks 24 are fixedly arranged on the lower surface of the second slider 15, and the measuring plate 16 is fixedly arranged on the upper surface of the second slider 15, when the second bidirectional screw 23 rotates, the distance between the two measuring plates 16 will gradually close. When the surfaces of the two measuring plates 16 close to each other contact the outer wall of the bearing, they stop moving. At this time, the staff can obtain the value of the outer diameter of the bearing by observing the second scale plate 31.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
