Problems solved by technology

[0002] During the processing of eccentric casing parts, it is necessary to carry out secondary clamping and alignment for the normal center and eccentric processing content respectively. The secondary clamping and alignment is not only time-consuming and laborious, but also has hidden quality problems, and it is difficult to distinguish small eccentricity. There will always be quality problems caused by eccentric clamping and alignment errors

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0029] like figure 1 and figure 2 As shown, taking an eccentric turbine casing as an example, the eccentric distance d between the origin of the eccentric circle of the casing and the origin of the part is 0.25mm, and there are 40 eccentric grooves on the eccentric surface to be processed, and the 40 eccentric grooves are centered on the origin of the eccentric circle. , evenly arranged on a circle with radius R=500mm.

[0030] like image 3 and Figure 4 Shown, a kind of machining method of casing eccentric groove, comprises the following steps:

[0031] S1. Under the coordinates of the origin of the part, the coordinates of the origin of the ecce...

Abstract

The invention discloses a machining method of an eccentric groove of a casing, and belongs to the technical field of eccentric casing machining. The machining method of the eccentric groove of the casing comprises the following steps that S1, under the origin coordinates of a part, the origin coordinates of an eccentric circle are changed along with rotation of the part, and the origin coordinatesof the eccentric circle after rotation are obtained; S2, the radius R of the eccentric circle is set according to the original point of the eccentric circle and the position of the eccentric groove;S3, according to the eccentric distance d between the original point of the eccentric circle and the original point of the part, the radius R of the eccentric circle and the rotation angle theta of the position of the eccentric groove relative to the original point of the eccentric circle, the rotation angle alpha of the position of the eccentric groove relative to the original point of the part is calculated through a trigonometric function; and S4, the eccentric groove is machined according to the rotation angle alpha of the position of the eccentric groove relative to the original point ofthe part under the coordinate of the original point of the part. According to the machining method for the eccentric groove of the casing, the machining requirements for normal center and eccentricitycan be met through one-time clamping, the clamping and aligning time is saved, and potential quality hazards caused by secondary clamping are eliminated.

Description

technical field [0001] The invention relates to the technical field of machining an eccentric casing, in particular to a method for processing an eccentric groove of a casing. Background technique [0002] During the processing of eccentric casing parts, it is necessary to carry out secondary clamping and alignment for the normal center and eccentric processing content respectively. The secondary clamping and alignment is not only time-consuming and laborious, but also has hidden quality problems, and it is difficult to distinguish small eccentricity. There will always be quality problems caused by eccentric clamping and alignment errors. Contents of the invention [0003] In order to solve the technical problems existing in the prior art such as the need for secondary clamping and alignment in the processing of eccentric casings, the present invention provides a processing method for casing eccentric grooves, which can realize normal center and eccentric processing throug...
