Problems solved by technology

Although this method solves the problem of machining some indexing grooves on wire cutting machine tools, it cannot be processed because the outer circle of the ferrule used for oil wells is threaded and cannot be clamped with its "V"-shaped positioning block.

Embodiment Construction

[0032] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0033] Such as figure 1 , figure 2 , image 3 Shown is a positioning and indexing device for processing ferrules for oil wells, the device includes:

[0034] Such as Figure 4 , Figure 5 , Figure 6 As shown in the index plate 1, the even-numbered index plate positioning holes 111 are evenly distributed on the lower end surface 11, and there are positioning screw holes 121 on the boss 12. The boss 12 supports the ferrule radially, and the upper end face 13 is used to align sleeve for axial positioning;

[0035] Such as Figure 7 The indexing plate positioning pin 2 shown is connected to the indexing plate positioning hole 111 and the vertical base positioning hole 51, and is used to connect the indexing plate and the vertical base to make the circumferential positioning of the ferrule;

[0036] Such as Figure 8 , Figure 9 As shown in the p...

Abstract

The invention relates to a positioning and indexing device for machining a cutting sleeve for a petroleum well and a machining method, and belongs to the technical field of linear cutting machining. The positioning and indexing device for machining the cutting sleeve for the petroleum well is characterized by comprising an indexing disc, indexing disc positioning pins, a positioning plate, a positioning plate positioning pin and a vertical base; the indexing disc and the positioning plate are connected through the positioning plate positioning pin so that the indexing disc can drive the cutting sleeve to rotate; an even number of indexing disc positioning holes are uniformly distributed in the lower end surface of the dividing disc in the circumferential direction at equal angles, and the dividing disc is connected to the vertical base through the indexing disc positioning pins so that the indexing disc can carry out circumferential equal-angle rotation indexing. Compared with the prior art, the device and the method have the advantages that axial horizontal positioning and circumferential equal-angle rotation indexing can be carried out rapidly when the cutting sleeve for the petroleum well is machined, in addition, positioning and indexing are simple, and therefore the working efficiency of operators can be obviously improved, and the machining yield of the cutting sleeve can be obviously increased.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a positioning and indexing device and a processing method for processing ferrules used in oil wells, and belongs to the technical field of wire cutting processing. Background technique [0002] A certain number of narrow grooves are evenly distributed in the circumferential direction of ferrules for oil wells, and the narrow grooves need to be processed by wire cutting machine tools. During processing, the ferrule needs to be positioned axially and horizontally so that the cutting line can pass through the centerline of the part vertically for cutting, and after processing two evenly distributed grooves, it is necessary to accurately and efficiently rotate the ferrule at an equal angle in the circumferential direction and Position for easy cutting of other narrow slots. The traditional wire cutting machine tool does not design a special positioning and indexing device for the pr...
