[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-4 A bearing diameter testing tool shown in the figure comprises a base plate 1, a boss 2 and a column 5 are provided on the top surface of the base plate 1, a slide groove 21 is provided on the top surface of the boss 2, two groups of fixed blocks 4 are slidably connected in the slide groove 21, in order to control the synchronous adjustment of the two groups of fixed blocks 4, an adjusting rod 3 is provided in the slide groove 21, and the adjusting rod 3 is provided with a threaded section with opposite rotation directions, so as to cooperate with the slide groove 21 to control the synchronous movement of the fixed block 4, and a coaxial turning handle is provided at one end of the adjusting rod 3 for controlling the rotation of the adjusting rod 3. After the bearing is fixed by the fixed block 4, a vernier caliper 11 fixed on the lifting mechanism is used to detect the bearing radius to improve the detection efficiency (in order to improve the accuracy, the fixed end of the vernier caliper is located at the midpoint of the two groups of fixed blocks 4).

[0024] The opposite surfaces of the two sets of fixing blocks 4 are provided with V-shaped grooves for fixing the bearings placed therebetween.

[0025] A lifting groove 51 is provided on the top surface of the column 5, and a lifting rod 6 for controlling the lifting of the lifting block 7 is rotatably connected inside the lifting groove 51. The lifting rod 6 is threadedly connected to the lifting block 7, and the lifting block 7 is rectangular and adapted to the lifting groove 51. A sliding hole 52 communicating with the outside is provided on the inner wall of the lifting groove 51, and a connecting member 10 is slidably connected in the sliding hole 52. The connecting member 10 is rotatably connected to the lifting block 7. In order to limit the connecting member 10, a limiter is provided on the top surface of the lifting block 7, and the limiter is slidably connected to the connecting member 10, and a vernier caliper 11 is detachably connected to the connecting member 10.

[0026] The connecting member 10 is rotatably connected to the lifting block 7 through the rotating block, and the outward end surface of the connecting member 10 is provided with a placement groove 101 for inserting the vernier caliper 11. In order to fix the vernier caliper 11, a top screw is provided on the connecting member 10. After the vernier caliper 11 is inserted, it is fixed with the top screw.

[0027] In order to detect the inner and outer diameters of the bearing, the present design achieves a 180-degree rotation of the vernier caliper 11 through the above-mentioned connecting piece 10. In order to stabilize the state after rotation, a symmetrical protrusion 8 is provided on the top surface of the lifting block 7, and a limit plate 9 is hinged on the protrusion 8, and a limit groove for the limit plate 9 to slide (to achieve limit) is provided on the end surface of the connecting piece 10; through the above-mentioned structure, when in use, the fixed end of the vernier caliper 11 is fixed to the midpoint of the two groups of fixed blocks 4. When detecting, only the sliding end needs to be moved to quickly detect the outer diameter of the bearing. When it is necessary to detect the inner diameter, the limit plate 9 is moved to achieve a 180-degree flip to detect the inner diameter.

[0028] The working principle of the utility model is as follows: by placing the bearing on the top surface of the boss 2 and rotating the handle, the handle drives the adjusting rod 3 to rotate, and controls the two sets of fixed blocks 4 to slide in the slide groove 21 to achieve fixed limit of the bearing. After the fixation is completed, the lifting rod 6 is driven to rotate by the handle of the lifting rod 6, thereby controlling the lifting block 7 to perform lifting movement in the lifting groove 51 of the column 5, so that the connecting piece 10 and the vernier caliper 11 are lowered (the sliding end of the vernier caliper 11 is moved in this process), and then the outer diameter (radius) of the bearing is detected; when it is necessary to detect the inner diameter, first move the limit plate 9 to separate its free end from the limit groove, release the limit on the connecting piece 10, and then rotate the connecting piece 10 to rotate 180 degrees. After the flipping is completed, the limit plate 9 is put back into the limit groove. After the switching is completed, the lifting mechanism is driven to achieve the detection purpose.
