Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] A combined processing method for multi-stage outer sealing ring components, such as figure 1 , figure 2 shown, including the following steps:

[0020] Step 1: Place the connection housing 4 on the base 2 and fix it. On the inner side wall of the connection housing 4, several installation grooves 13 for outer sealing ring components and connectors are continuously arranged;

[0021] Step 2: In order to prevent deformation of the connecting shell 4, fix the upper end of the connecting shell 4 on the bracket 1;

[0022] Step 3: Alternately install the outer sealing ring components and connectors in the installation groove 13 of the connecting shell 4 until the outer sealing ring components and connectors at all levels are installed. The specific installation steps are as follows:

[0023] Step A: Install the first-level outer ...

Abstract

The invention belongs to the technical field of machining and provides a multistage outer tightly-sealed ring component combined machining method through which surface machining quality and accuracy uniformity of outer tightly-sealed ring components can be guaranteed after mounting and demounting for many times. The multistage outer tightly-sealed ring component combined machining method can solve the machining problem of multistage outer tightly-sealed ring components, and is convenient to operate and simple in machining. The method includes the following steps: step 1, placing a connecting shell on a base, and fixing the connecting shell, wherein a plurality of mounting grooves of the outer tightly-sealed ring components and connecting members are continuously formed in the inner side wall of the connecting shell; step 2, alternatively mounting the outer tightly-sealed ring components and the connecting members in the mounting grooves of the connecting shell sequentially until the outer tightly-sealed ring components and the connecting members at each stage are mounted fully; step 3, placing parts after combined mounting into machining equipment for machining.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a combined processing method for multi-stage outer sealing ring components. Background technique [0002] At present, in the field of aero-engine mechanical processing, the processing method of the outer sealing ring assembly adopts the processing method of the single-stage outer sealing ring assembly, and there are many application examples of this processing method; while the processing method of the multi-stage outer sealing ring assembly is almost No. The processing method of the single-stage outer sealing ring assembly is cumbersome and complicated, and it is difficult to ensure the consistency of the surface processing quality and precision of the outer sealing ring assembly after repeated assembly and disassembly. [0003] Moreover, the processing of multi-stage outer sealing ring components will be a development trend in the future, so it is imp...
