[0033] As a preferred solution of the present invention, the positioning mechanism includes: an unlocking plate 8, a vertical rod 9, a transmission plate 11 and a pull rod 12;

[0034] The unlocking plate 8 is slidably connected to the right side of the connecting plate 7, the vertical rod 9 is fixedly connected to the bottom of the unlocking plate 8, and the vertical rod 9 passes through the connecting plate 7, the transmission plate 11 is fixedly connected to the bottom of the vertical rod 9, the pull rod 12 is rotatably connected to the front side of the transmission plate 11, and the rear side of the pull rod 12 is rotatably connected to the front side of the positioning rod 13. When the unlocking plate 8 moves, the vertical rod 9 will be driven downward, and at the same time, when the unlocking plate 8 moves, the transmission plate 11 will be driven to move. When the transmission plate 11 moves, the pull rod 12 will be pulled, and when the pull rod 12 moves, the positioning rod 13 will be pulled to the right. When the positioning rod 13 moves, it will disengage from the positioning groove, thereby unlocking the slide plate 6.

[0035] As a preferred solution of the present invention, the top of the connecting plate 7 is fixedly connected with a reset spring 10, and the bottom of the unlocking plate 8 is fixedly connected to the top of the reset spring 10. The elastic force of the reset spring 10 facilitates the upward movement and reset of the unlocking plate 8.

[0038] As a preferred solution of the present invention, the front side of the connecting plate 7 is fixedly connected to the limiting spring 14, and the left side of the limiting spring 14 is fixedly connected to the right side of the positioning rod 13. Through the elastic force of the limiting spring 14, the positioning rod 13 is conveniently pushed to move horizontally and reset to engage with the positioning groove.

[0039] It should be noted that the specific type of torsion spring table 2 to be used is selected by relevant technical personnel familiar with this field, and the above torsion spring table 2 and the like belong to the existing technology and will not be elaborated in this solution.

[0040] The working principle of the present invention is as follows: in actual use, when it is necessary to measure the sealing groove of the bearing ring, first, according to the needs of use, the fixing sleeve 5 of appropriate size is fixed to the slide plate 6 and the fixing plate 4 by screws, and a positioning groove is opened at the corresponding position on the right side of the support plate 3. When the bearing ring needs to be fixed, the unlocking plate 8 is first pushed down. When the unlocking plate 8 moves, the vertical rod 9 is driven to move down. At the same time, when the unlocking plate 8 moves, the reset spring 10 is compressed. At the same time, when the vertical rod 9 moves, the transmission plate 11 is driven to move. When the transmission plate 11 moves, the pull rod 12 is pulled. When the pull rod 12 moves, the positioning rod 13 is pulled to the right. When the positioning rod 13 moves, the limit spring 14 is compressed. At the same time, the support sleeve 15 limits the positioning rod 13, so that the positioning rod 13 moves stably laterally. At this time, the positioning rod 13 moves to the right and is out of contact with the positioning groove, thereby causing the slide plate 6 to move. When unlocked, the bearing ring to be measured can be placed on the top of the fixed sleeve 5 below. By pushing the connecting plate 7 to move, the slide plate 6 will be driven to slide, and the movement of the slide plate 6 will drive the fixed sleeve 5 to move down. The bearing ring is clamped and fixed by the cooperation of the two fixed sleeves 5. At this time, the unlocking plate 8 is released, and the reset spring 10 loses its restriction and pushes the unlocking plate 8 to move up and reset. The reset of the unlocking plate 8 will pull the vertical rod 9 up, and the movement of the vertical rod 9 will drive the transmission plate 11 to move up, thereby driving the pull rod 12 to reset. At this time, the limit spring 14 loses its restriction and pushes the positioning rod 13 to move horizontally. The horizontal movement of the positioning rod 13 will engage with the positioning groove to fix the slide plate 6 and the connecting plate 7, so that the fixed sleeve 5 is fixed. By fixing the fixed sleeve 5, the bearing ring is kept fixed. At this time, the bearing ring sealing groove can be measured by taking the torsion spring gauge 2, which has good practicality.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
