Embodiment Construction

[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0039] A turning method for cylindrical stepped thin-walled parts, the turning method is used for processing and manufacturing cylindrical stepped thin-walled parts, the structural schematic diagram of the cylindrical stepped thin-walled parts is as follows figure 1 As shown, it includes small outer circle 1, small hole 2, large outer circle 5, and large hole 6. Semi-finished products are reserved during rough machining, including outer ring groove 3 and ...

Abstract

The invention discloses a turning method for a cylindrical stepped thin-wall part. According to the method, during rough machining, an outer circular groove and an inner hole step are reserved; when asmall outer circle is clamped, a large hole is finely bored, and a large outer circle is finely turned; when the large outer circle is clamped, a small hole is finely bored, the small outer circle isfinely turned, and cotton adhesive tape, high-density foam blocks and other materials are utilized for achieving a cushioning effect when the cylindrical stepped thin-wall part is turned; stress canbe released in advance through the reserved outer circular groove and inner hole step, the influence on the size precision of the other end can be reduced when one end is finely machined, and therefore part deformation is reduced, and the size precision is improved; and the turning method is economical and suitable for small-scale production of new products.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing technology, and in particular relates to a turning method of a cylindrical stepped thin-walled part. Background technique [0002] my country's manufacturing industry is developing rapidly, and the demand for high-precision thin-walled parts is increasing. Because such parts have the characteristics of poor rigidity, light weight, high dimensional accuracy requirements, and easy deformation during processing, and there may be many places on the thin-walled parts. The hole is lightened, and the rigidity is worse, which makes it easy to vibrate the tool during finishing machining, the surface quality of the parts cannot be effectively controlled, the product failure rate is high, and even the accuracy of the assembly is affected. [0003] At present, in order to overcome the problems of easy deformation and vibration in the processing of such parts, most manufacturers only make improvem...
