[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following structure, the description of the well-known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1-4The tooling shown in the figure for detecting the inner and outer ring raceways of bearings and the surface appearance of steel balls includes a support 100 for supporting other components, which is movably connected to the bottom of a detection device 200 via a rotating shaft 110.

[0026] The support 100 includes a first support body 101 and a second support body 102 , and the rotating shaft 110 passes through the mounting holes of the first support body 101 and the mounting holes of the second support body 102 for installation.

[0027] The detection device 200 as a whole can rotate along the rotating shaft 110 , and the rotation position can be controlled by a rotating locking member 111 provided on one side of the rotating shaft 110 .

[0028] A bearing inner ring support ring 210 is arranged at the front end of the detection device 200. The bearing inner ring support ring 210 is a plurality of cylindrical members with gradually decreasing diameters. The purpose of such arrangement is to facilitate the fixing of bearing inner rings of different diameters.

[0029] The bearing inner ring 300 passes through the bearing inner ring support ring 210 and is supported on the outer periphery of the bearing inner ring support ring 210. The rear end of the detection device 200 is provided with a support bracket 220 for placing the bearing outer ring 400. The support bracket 220 includes two support brackets, one on the left and one on the right.

[0030] A plurality of steel ball placement grooves 230 with different diameters are arranged at the upper end of the detection device 200. The plurality of steel ball placement grooves 230 with different diameters are different groups of steel ball placement grooves arranged from large to small in diameter. A rotating core rod 240 is penetrated below the steel ball placement grooves 230 to drive the steel ball 500 to rotate.

[0031] Because of the above structure, the working principle of the utility model is:

[0032] The steel ball 500 is placed in the corresponding top steel ball placement groove 230, and the steel ball 500 is driven to rotate by rotating the core rod 240 to observe whether there are defects on the surface of the steel ball.

[0033] The bearing inner ring 300 is placed in a suitable bearing inner ring support ring 210, and the bearing inner ring 300 can be directly rotated manually to observe 360° whether there are defects on the bearing inner ring 300 raceway.

[0034] The bearing outer ring 400 is placed on two supporting brackets, one on the left and one on the right. The bearing outer ring 400 can be manually rotated to observe whether there are defects on the raceway of the bearing outer ring 400.

[0035] After the observation is completed, the angle of the detection device 200 is adjusted by rotating the rotating shaft 110, such as performing a flipping operation.
