Specific embodiment
Describe in detail the particular content of the present invention with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, bearing inner race roller groove polishing special tooling, including：Frame 1, in the upper of the frame 1
End outside is evenly arranged with some cylinders 2, fixed block 4 is provided with the piston rod 3 of the cylinder 2, in the fixed block 4
Upper end is provided with L-type fixture block 5, arc card is provided with the outside of the upper end of the L-type fixture block 5 and sets raised 6, and the arc card sets convex
Play 6 to be arranged concentrically with the dead eye 8 of bearing inner race 7, be evenly arranged with the frame 1 between the cylinder 2 and L-type fixture block 5
Some horn-like suction ports 9, the horn-like suction port 9 is connected respectively by sweep-up pipe 10 with dust exhaust apparatus 11, described
The upper end of dust exhaust apparatus 11 is provided with control device 12, and wherein the lower end of a cylinder 2 is provided with traveller 13, the fixed block
4 lower slide is arranged on traveller 13, is slided on the traveller 13 between the fixed block 4 and cylinder 2 and is provided with pressure biography
Sensor 14, is arranged with spring 15 on the traveller 13 between the pressure sensor 14 and cylinder 2, one end of the spring 15 with
