Embodiment

[0037] Example: The processing of a thin-walled 1-2 mm weakly rigid "rim" part of a disc.

[0038] See attached Figure 1~5 , carry out processing according to the following steps:

[0039] Step 1: Local unconstrained clamping of parts. Such as figure 1 , clamp the revolving part 2 with the fixture 1 once on the horizontal lathe, and place the thin-walled "rim" part 3 of the revolving part 2 in an unconstrained free state. Avoid plastic deformation due to the influence of other limiting factors when the profiles at both ends of the part are processed in the same process.

[0040] Step 2: single-process layered cycle rough turning. Such as figure 2 , according to the sequence of turning paths marked in ①~⑤ and the corresponding tool type used, quasi-symmetrical rough turning of the profile at both ends of the "rim" part 3, leaving a margin of 1 to 1.5 mm to achieve rough removal of excess profiles at both ends The purpose of measuring and trimming the amount of deformati...

Abstract

The invention discloses a method for turning a complex thin-wall part profile by adopting a quasi-symmetric layered circulation. The method is characterized in that the integral part of a rotary bodypart is clamped in a local unrestraint mode, and the two ends profiles of the complicated thin-walled part to be machined are placed in an unconstrained free state, then a single-step layered circulation is adopted, and the quasi-symmetric layered turning mode of rough turning, semi-finish turning, fine turning and the finish turning are sequentially adopted in one procedure so as to turn the twoends profiles of the part to be machined. According to the method, only one procedure and one clamping are needed, and the machining of the local two ends profiles of the part can be completed, the part does not need to be turned over in the machining process, and the deformation control effect is good.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a deformation control method for turning complex thin-walled part profiles by quasi-symmetric layered cycle turning. Background technique [0002] For the processing of the local two-end profile of the rotary part, it is usually divided into two processes on the lathe. First, after the profile of one end of the part is processed, the part is turned over to process the profile of the other end. However, when this method is used to process the profiles at both ends of the part with complex and thin-walled parts, it often occurs that the profile at one end that has been processed is affected by the cutting force of the other end to collapse and deform. product quality. Contents of the invention [0003] The invention provides a quasi-symmetric layered cycle turning method, which is used to process the local complex thin-walled end profiles of the revolving body pa...
