[0014] The following will be combined with the drawings of this specification to clearly and completely describe the technical solution of the utility model. It should be noted that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0015] See also Figure 1-Figure 3A measuring platform for testing bearing rings, comprising a workbench 1, a positioning groove A2, a limiting rod A6, a measuring gauge 5 and an air source 9. The workbench 1 is a horizontally arranged rectangular table. The surface of the workbench 1 is provided with a positioning groove A2. One end of the positioning groove A2 is provided with a measuring gauge 5. The positioning groove A2 is provided with a limiting rod A6 that can move therein. The surface of the workbench 1 is evenly provided with air holes 103. One side of the workbench 1 is provided with an air inlet 101. The air source 9 is connected to the air inlet 101 provided on the workbench 1 through an air pipe. Positioning grooves B3 and C4 are provided on both sides of the positioning groove A2, respectively. The angle between the positioning groove A2 and the positioning groove B3 is 45°. The positioning groove B3 is provided with a limiting rod B7 that can move therein. The angle between the positioning groove A2 and the positioning groove C4 is 45°. The positioning groove C4 is provided with a limiting rod C8 that can move therein. The workbench 1 is provided with a rectangular cavity 102 inside, and the upper part of the rectangular cavity 102 is connected to the air hole 103 provided on the surface of the workbench 1. The rectangular cavity 102 is connected to the air inlet 101 on one side of the workbench 1, and is connected to the air source 9 through the air inlet 101. The positioning groove A2, positioning groove B3 and positioning groove C4 are all "T"-shaped grooves, and the limit rods A6, limit rods B7 and limit rods C8 provided in the grooves are all provided with "T"-shaped sliders that match the corresponding groove bodies; the rod bodies of the limit rods A6, limit rods B7 and limit rods C8 are all provided with annular bosses for contacting the outer wall of the bearing ring 10.

[0016] When the utility model is in use:

[0017] First, place the bearing ring 10 on the surface of the workbench 1 so that the outer wall of the bearing ring 10 contacts the top of the measuring gauge 5. Next, open the air source 9 and connect it to the air inlet 101 of the workbench 1 through the air pipe. The gas generated by the air source 9 flows into the rectangular cavity 102 of the workbench 1 through the air inlet 101. The gas in the rectangular cavity 102 is discharged outward through the air hole 103 provided on the workbench 1. The continuous gas makes the bottom surface of the bearing ring 10 not fit tightly with the surface of the workbench 1 and difficult to move. Then move the limit rod A6 in the positioning groove A2 so that the limit rod The annular boss of A6 contacts the outer wall of the bearing ring 10, and then the limit rod B7 in the positioning groove B3 and the limit rod C8 in the positioning groove C4 are moved to make the diameter of the bearing ring 10 coincide with the center line of the positioning groove A2, and the limit rod A6, the limit rod B7 and the limit rod C8 are fixed on the corresponding positioning groove A2, the positioning groove B3 and the positioning groove C4 respectively; at this time, observe the value of the measuring table 5 and write it down, and then rotate the bearing ring 10 while observing whether the value of the measuring table 5 changes with the written value, so as to judge whether the bearing ring 10 is elliptical or not.
