Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The present invention will be further explained with reference to the drawings and examples.

The utility model is realized by the following technical proposal, as shown in figures 1-5,

on the one hand, the clamp for measuring the surface roughness of the sphere 3 comprises a support body 2 provided with a sphere installation counter bore 22 and a limiting block 21 arranged on one side, far away from the sphere installation counter bore 22, of the support body 2.

In some possible embodiments, as shown in fig. 1 and 3, the sphere mounting counterbore 22 is provided with an inner R-face 23 that is surface-fitted with the sphere 3.

Preferably, as shown in FIG. 3, the ball mounting counterbore 22 is a cylindrical groove with an inner R face 23 disposed on the top surface of the cylindrical groove.

An inner R surface 23 is arranged on the top surface of the cylindrical groove and serves as a supporting surface, so that the outer surface of the spherical surface is effectively supported;

on the other hand, as shown in fig. 4-5, a tool for measuring the surface roughness of a sphere 3 comprises the measuring clamp, a workbench 1 provided with a limiting groove, and a measuring instrument installed on the workbench 1; the limiting block 21 is installed in the limiting groove.

In some possible embodiments, the measuring instrument comprises a column 5 installed on the workbench 1, and a roughness meter 4 slidably installed on the column 5 and moving along the length direction of the column 5, wherein a measuring pin 41 of the roughness meter 4 is positioned right above the sphere installation counterbore 22.

After the ball body 3 is installed, the roughness meter 4 which is slidably installed on the upright post 5 is controlled to slide vertically, and the roughness meter 4 is fixed vertically after the roughness meter 4 moves to a proper position through the adjusting handle 6; so that the measuring pin 41 of the coarseness gauge 4 is positioned right above the sphere 3; the measurement of the surface roughness of the sphere 3 is then achieved by controlling the movement of the stylus 41 in the horizontal direction.

In some possible embodiments, the cross section of the limiting groove is an inverted T shape, and the opening of the limiting groove is arranged on one side close to the measuring pin 41.
