Example (b):
referring to fig. 1-4, a nut machining and positioning device comprises an installation table 1, an annular tooth 5, a positioning block 7 and a bearing 4.
Specifically, the mounting platform 1 is a square block structure, and after the mounting platform 1 is placed on a horizontal plane, the top surface of the mounting platform has an annular connecting groove 10.
The inner side of one end of the annular tooth 5 is provided with an inward convex structure, and the tooth of the annular tooth 5 is positioned on the convex structure and is provided as the inner side tooth of the annular tooth 5.
The other end activity of annular tooth 5 is located in spread groove 10, and the one end that annular tooth 5 is located spread groove 10 is fixed to be located on the inner race of bearing 4, and the outer lane of this bearing 4 is fixed to be located on spread groove 10 inner wall for annular tooth 5 can be at spread groove 10 internal rotation.
The annular tooth 5 has an inner tooth end projecting from the top surface of the mount table 1, and the mount table 1 is located in the connecting groove 10 and has a table 8.
The positioning block 7 is long-strip-shaped, two ends of the positioning block 7 are both arc-shaped structures, and the diameter of one end of the positioning block 7 is larger than that of the other end.
The end with the large diameter of the positioning block 7 is rotatably connected to the workbench 8 through a rotating shaft, the outer side of the end of the positioning block 7 is provided with teeth meshed with the inner side teeth on the annular teeth 5, meanwhile, the axis of the rotating shaft is collinear with the axis of the end of the positioning block 7, and the other end of the positioning block 7 is a movable end.
Three or six positioning blocks 7 are uniformly distributed on the periphery of the axis of the ring connecting groove 10 on the workbench 8. When the ring-shaped teeth 5 are rotated, the movable ends of all the positioning blocks 7 can simultaneously approach or depart from the axis of the ring-shaped teeth 5.
The working principle of the embodiment is as follows: the mounting table 1 is first fixed to the machining bed and then the ring gear 5 is rotated so that all the positioning blocks 7 rotate inside the ring gear 5. Because one end of the positioning blocks 7 is rotatably connected to the mounting table 1, when the annular teeth 5 are rotated, the other ends of all the positioning blocks 7 can simultaneously approach or depart from the axis of the annular teeth 5.
