Problems solved by technology

The rigidity of thin-walled parts is poor, and the secondary clamping is easy to cause clamping deformation. In addition, the lack of accurate positioning and orientation references makes it difficult for the secondary processing reference to coincide with the first processing reference, and it is difficult to obtain high processing accuracy.

Embodiment Construction

[0031] The invention provides a method for processing thin-walled semicircular parts. The method for processing thin-walled semicircular parts comprises the following steps:

[0032] 1) Prepare tube or bar;

[0033] 2) Set up a process extension at either end of the tube or bar;

[0034] 3) Set reference holes on the end face of the process extension; the reference holes are arranged in pairs symmetrically along the center of the tube or bar; and the angular position between each pair of reference holes is related to the position of the shape element of the part . For example figure 1 , radial small hole, , the hole and the R arc surface have an angle requirement of а°, when the paired reference holes are set at the extended end, as shown in Figure 3, the angle between BB' and AA' and the fixture between CC' and AA' Both are а°, a single part has only one radial hole, the full circle processing is two radial holes, straighten the vertical direction of the positioning pin on...

Abstract

The invention relates to a method for processing thin-wall semi-circular parts. The method comprises the following steps: (1) pipe material or bar material is prepared; (2) any end part of the pipe material or bar material is provided with a technical extending section; (3) the end surface of the technical extending section is provided with a datum hole; (4) technical processing is carried out on the pipe material or bar material through the datum hole; (5) the processed pipe material or bar material is segmented; and (6) the technical extending section is removed. The invention provides a method for processing the thin-wall semi-circular parts, which can improve the processing precision, is convenient to operate and can reduce the investment cost of equipment.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a processing technology of parts, in particular to a method for processing thin-walled semicircular parts. Background technique [0002] For thin-walled parts with characteristic shapes in both the axial and radial directions, the five-axis vertical-horizontal conversion equipment is basically used for one-time processing, and then heat treatment is performed. The precision of the parts depends on the degree of deformation of the heat treatment. The rigidity of thin-walled parts is poor, and the secondary clamping is easy to cause clamping deformation. In addition, the lack of accurate positioning and orientation references makes it difficult for the secondary processing reference to coincide with the first processing reference, and it is difficult to obtain high processing accuracy. Contents of the invention [0003] In order to solve the above-mentioned technical problems i...
