Abstract

The present invention relates to a kind of process of assembling cover plate, the method comprises the following steps: 1) increase false boss at the end of thread of cover plate; 2) utilize and to act on the suitable frock of false boss on false boss and assembled by the end of thread of cover plate and volute.The invention provides a kind of process avoiding cover plate stress deformation, qualification rate is high and assembly quality is stable assembling cover plate in assembling process.

Description

A kind of process of assembling cover plate
Affiliated field
The invention belongs to field of machining, relate to a kind of process of assembling cover plate.
Prior art
During certain type booster pump scroll assembly assembling cover plate, first use frock holddown plate large end face, cover plate is screwed in volute, cover plate large end face is under the effect of thrust and revolving force, cover plate is easily deformed, and make cover plate and volute cannot meet the designing requirement of only leaning on, qualification rate is lower in process of production, quality is unstable, and product exists potential safety hazard.
Summary of the invention
In order to solve the above-mentioned technical problem existed in background technology, the invention provides a kind of process avoiding cover plate stress deformation, qualification rate is high and assembly quality is stable assembling cover plate in assembling process.
Technical solution of the present invention is: the invention provides a kind of process of assembling cover plate, its special character is: said method comprising the steps of:
1) false boss is increased at the end of thread of cover plate;
2) utilize and to act on the suitable frock of false boss on false boss and assembled by the end of thread of cover plate and volute.
Above-mentioned steps 2) specific implementation be:
2.1) measure and record volute end face to the distance h1 between volute and cover plate faying face, measurement record cover plate large end face to the distance h2 between volute and cover plate faying face;
2.2) simulate assemble is carried out to cover plate and volute, cover plate is screwed in volute by the cover plate end of thread, cover plate and volute are only close together, simulate assemble groove is carried out to the position of the large end face place volute of cover plate simultaneously;
2.3) gluing is carried out to the end of thread of cover plate;
2.4) practical set is carried out to cover plate and volute, cover plate is screwed in volute by the cover plate end of thread, be threaded through simulate assemble groove, measure the distance h3 of volute end face to cover plate large end face, until the value of h3 is not more than the difference between h1 and h2 simultaneously.
Above-mentioned steps 2.4) in cover plate is screwed in volute by the cover plate end of thread, and be threaded through simulate assemble groove 0 ~ 3mm.
Above-mentioned steps 2.2) in cover plate be screwed into by the cover plate end of thread moment adopted in volute be not more than 10nm.
Above-mentioned steps 2.4) in cover plate be screwed into by the cover plate end of thread moment adopted in volute be not more than 80nm.
The technique of above-mentioned assembling cover plate is in step 2) after also comprise and remove the step of false boss.
Above-mentioned false boss adopts the mode of turning to remove from the small end face of cover plate.
During above-mentioned turning, the direction of Cutting Force is consistent with the direction that cover plate screws.
Advantage of the present invention is:
The present invention in order to avoid cover plate install before stress deformation, adopt and change covering plate structure, false boss is increased at the cover plate end of thread, be convenient to assembling, cover plate has assembled this false boss of rear removal, this false boss is with the groove being easy to clamp or hole, and groove or hole are axially uniform at false boss, can be flat recess, cross recess etc.The method can apply to the assembling of similar structures thin-walled parts, effect is very good, improves the reliability of product quality and work, solves cover plate and touches problem, avoiding the aero-engine fuel oil caused after cover plate touches mill is mixed in lubricating oil, causes great aircraft accident; Meanwhile, the method is simple and direct feasible, convenient operation, and improve qualification rate in process of production, assembly quality is guaranteed.

Detailed description of the invention
The invention provides and provide a kind of process of assembling cover plate, the process of this assembling cover plate comprises the following steps:
1) false boss (structure of false boss refers to Fig. 1 a and Fig. 1 b, and this false boss is with the groove being easy to clamp or hole, and groove or hole are axially uniform at false boss, can be the structures such as flat recess, cross recess) is increased at the end of thread of cover plate;
2) utilize and to act on the suitable frock (referring to Fig. 2) of false boss on false boss and assembled by the end of thread of cover plate and volute:
2.1) measure and record volute end face to the distance h1(between volute and cover plate faying face see Fig. 3), measure and record cover plate large end face to the distance h2(between volute and cover plate faying face see Fig. 4);
2.2) simulate assemble is carried out to cover plate and volute, cover plate is screwed in volute by the cover plate end of thread, cover plate and volute are only close together, simulate assemble groove is carried out to the position of the large end face place volute of cover plate simultaneously; The moment adopted is not more than 10nm;
2.3) gluing is carried out to the end of thread of cover plate; First fill sealing ring, then at cover plate threaded portion gluing, during gluing, glue should not be too thick but want evenly, should not make on adhesive sealing circle.
2.4) practical set is carried out to cover plate and volute, cover plate is screwed in volute by the cover plate end of thread, be threaded through simulate assemble groove 0 ~ 3mm, measure the distance h3(of volute end face to cover plate large end face see Fig. 5 simultaneously), until the value of h3 is not more than the difference between h1 and h2; The moment adopted is not more than 80nm.
3) false boss is removed; Adopt the mode of turning to remove false boss from the small end face of cover plate, during turning, the direction of Cutting Force is consistent with the direction that cover plate screws.
