[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of the present invention. In addition, in the following structures, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0023] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] Such as Figures 1-3An outer diameter grinding device for a through-groove ball screw nut product with an outer diameter distribution as shown, including a driving base 100. The driving base 100 is an annular hollow driving base, and a number of locking part mounting holes 101 are penetrated through the annular hollow driving base. Specifically, three locking part mounting holes 101 can be set to be used in combination with the locking part 110.

[0025] A positioning structure 120 is arranged inside the annular hollow driving base 100. The positioning structure 120 includes an annular positioning block 121 at the bottom and a number of positioning driving keys 122 arranged on the first annular surface of the annular positioning block 121. The number of positioning driving keys 122 are the first positioning driving key 1221, the second positioning driving key 1222, and the third positioning driving key 1223 arranged on the first annular surface. The first positioning driving key 1221, the second positioning driving key 1222, and the third positioning driving key 1223 are equidistantly arranged, and the included angle between them is 120°.

[0026] The installation height of the annular positioning block 121 does not exceed the thickness of the annular hollow driving base 100. The positioning structure 120 and the driving base 100 are locked through the locking part 110.

[0027] A driving screw mounting hole 102 is penetrated through the annular hollow driving base 100. The driving end 131 of the driving screw 130 is connected to the screw end 132.

[0028] The driving end of the driving screw 130 extends into the driving screw mounting hole 102 and contacts the ball screw nut product 200 mounted on the positioning structure 120. In addition, the first positioning driving key 1221, the second positioning driving key 1222, and the third positioning driving key 1223 contact the through-groove or through-keyway 201 on the outer peripheral surface of the ball screw nut product 200.

[0029] Due to the above structure, the working principle of the present utility model is as follows:

[0030] First, the positioning structure 120 is installed inside the driving base 100. After the positioning structure 120 and the driving base 100 are locked through the locking part 110, the driving end of the driving screw 130 extends into the driving screw mounting hole 102 and contacts the ball screw nut product 200 mounted on the positioning structure 120.

[0031] The first positioning driving key 1221, the second positioning driving key 1222, and the third positioning driving key 1223 are made to contact the through-groove or through-keyway 201 on the outer peripheral surface of the ball screw nut product 200.

[0032] Install the assembled product tooling assembly onto the center of the cylindrical grinder. Place the end of the drive screw 130 at the left drive end of the machine tool. The center of the machine tool abuts against the chamfer of the other end of the positioning structure 120 (not shown in the figure). The center hole 202 at the other end of the product contacts the elastic part on the right side.

[0033] By adjusting the distance between the two centers of the machine tool, ensure that an appropriate center force is applied. This force will clamp the product and the tooling together without separation, and the product will not loosen during the processing. Also, it will not be too tight to cause abnormal friction and vibration, which may affect the processing accuracy. Then start the equipment for production and processing.

[0034] The above shows and describes the basic principles, main features, and advantages of the utility model.

[0035] Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
