specific Embodiment approach 1

[0013] Specific implementation mode one: as Figure 4 As shown, in this embodiment, a method for processing the outer circular chute of a cavity-shaped thin-walled part is carried out according to the following steps:

[0014] 1. Select the turning-milling compound machining center as the processing equipment, select the keyway milling cutter as the tool, and use the first tooling 1 and the second tooling 2 to clamp the workpiece 3 with the outer circular chute to be processed; the workpiece 3 with the outer circular chute to be processed is The material is K648 high precision casting;

[0015] 2. Carry out groove milling on the workpiece 3 with the outer circular chute to be processed by turning from the small end to the large end, so as to obtain a cavity-shaped thin-walled part with an outer circular chute.

[0016] In this embodiment, the turning-milling compound machining center is selected as the processing equipment, which has high machining accuracy and high accuracy ...

specific Embodiment approach 2

[0017] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the parameters of the turning-milling compound machining center described in step 1 are axial positioning and radial positioning accuracy of 0.005mm, repeat positioning accuracy of 0.005mm, and the maximum spindle speed of 3000r / m, the maximum milling power of the spindle is 20kw. Others are the same as the first embodiment.

specific Embodiment approach 3

[0018] Specific implementation mode three: as figure 2 As shown, the difference between this embodiment and the specific embodiment 1 or 2 is that the keyway milling cutter described in step 1 is composed of a front cutter part 4, a cutter bar 5 and a rear cutter part 6, and the cutter bar 5 is cylindrical. The front knife portion 4 and the rear knife portion 6 are arranged symmetrically along the center of the cutter bar 5; the front knife portion 4 and the rear knife portion 6 are respectively provided with two groups of cutting edges, and the two groups of cutting edges are all helically arranged. The cutter bar 5, the flank portion 6 and the cutter bar 5 are all arc transitions; the length of the cutting edge is the depth of the chute to be processed plus 0.5mm. Others are the same as those in Embodiment 1 or 2.

[0019] The keyway milling cutter in this embodiment can not only complete the product processing of cavity-shaped thin-walled parts with outer circular incline...

Abstract

The invention provides a processing method of an outer circle inclined groove of a cavity-shaped thin wall element, and relates to the processing method of the outer circle inclined groove of the cavity-shaped thin wall element. The processing method provided by the invention aims at solving the problems of hard materials of the cavity-shaped thin wall element and difficult processing of the outercircle inclined groove. The processing method comprises the following steps of 1, selecting a turn milling composite processing center as processing equipment; selecting a keyseat cutter as a cutter;using a first tooling and a second tooling for installing and clamping an outer circle inclined groove workpiece to be processed, wherein the outer circle inclined groove workpiece to be processed ismade of K648 high alloy castings; 2, performing groove milling on the outer circle inclined groove workpiece to be processed in a mode of performing turning and milling from the small head end to thebig head end; thus obtaining the cavity-shaped thin wall element with the outer circle inclined groove. The processing method provided by the invention is used for processing the outer circle inclined groove of the cavity-shaped thin wall element.

Description

technical field [0001] The invention relates to a processing method for an outer circular chute of a cavity-shaped thin-walled part. Background technique [0002] The structure of the cavity-shaped thin-walled part is a rotating body, which belongs to the deep-cavity thin-walled part, and it is very easy to deform when clamping. The wall thickness is generally 1.5mm to 2mm, and a set of chute grooves are processed on the outer circle of the rotating body. After processing the chute grooves, the wall thickness is only about 0.45mm to 0.75mm, and the dimensional tolerance and shape tolerance requirements are very strict. At the same time, the material is K648 high alloy precision casting, which is hard and difficult to process, and cannot be processed under normal conditions. Contents of the invention [0003] The invention aims to solve the problem that the material of the cavity-shaped thin-walled part is hard and the outer circular chute is difficult to process, and prov...
