Abstract

The invention relates to a process method for assembling a cover plate. The process method comprises the following steps of: (1) additionally arranging a process boss at the threaded end of the cover plate; and (2) acting a tool which is adaptive to the process boss on the process boss and assembling the cover plate and a volute casing through the threaded end of the cover plate. The process method for assembling the cover plate, disclosed by the invention, can prevent the cover plate from deforming by stress in the assembly process, and the assembled cover plate is high in percent of pass and stable in assembling quality.

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, use first frock holddown plate large end face, cover plate is screwed in the volute, the cover plate large end face is under the effect of thrust and revolving force, cover plate is easily deformed, so that cover plate and volute can't satisfy the designing requirement of only leaning on, qualification rate is lower in process of production, quality is unstable, and there is potential safety hazard in product.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technology, the invention provides a kind of process of 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) end of thread at cover plate increases false boss;
2) utilize and to act on the false boss with the suitable frock of false boss and the end of thread and volute by cover plate assemble.
Above-mentioned steps 2) specific implementation is:
2.1) measure and record the volute end face to the distance h 1 between volute and the cover plate faying face, measurement and record the cover plate large end face to the distance h 2 between volute and the cover plate faying face;
2.2) cover plate and volute are simulated assembling, cover plate is screwed in the volute by the cover plate end of thread, cover plate and volute only are close together, simultaneously the assembling groove is simulated in the position of the large end face place volute of cover plate;
2.3) end of thread of cover plate is carried out gluing;
2.4) cover plate and volute are carried out practical set, cover plate is screwed in the volute by the cover plate end of thread, twisted simulation assembling groove, measure simultaneously the volute end face to the distance h 3 of cover plate large end face, until the value of h3 is not more than the difference between h1 and the h2.
Above-mentioned steps 2.4) in cover plate is screwed in the volute by the cover plate end of thread, and twisted simulation assembling groove 0~3mm.
Above-mentioned steps 2.2) in cover plate is screwed into the moment that adopts in the volute by the cover plate end of thread and is not more than 10nm.
Above-mentioned steps 2.4) in cover plate is screwed into the moment that adopts in the volute by the cover plate end of thread and is not more than 80nm.
The technique of above-mentioned assembling cover plate is in step 2) also comprise afterwards the step of removing false boss.
Above-mentioned false boss is to adopt the mode of turning to remove from the small end face of cover plate.
The direction of Cutting Force is consistent with the direction that cover plate screws during above-mentioned turning.
Advantage of the present invention is:
Stress deformation before the present invention installs for fear of cover plate, adopt and change covering plate structure, increase false boss at the cover plate end of thread, be convenient to assembling, this false boss of removal after the cover plate assembling is finished, this false boss is with the groove that is easy to clamping 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, has improved the reliability of product quality and work, has solved cover plate and has bumped problem, the aero-engine fuel oil of having avoided cover plate to bump causing behind the mill is sneaked in the lubricating oil, causes great aircraft accident; Simultaneously, the method is simple and direct feasible, and convenient operation has improved in process of production qualification rate, and assembly quality is guaranteed.

The specific embodiment
The invention provides provides a kind of process of assembling cover plate, and the process of this assembling cover plate may further comprise the steps:
1) end of thread at cover plate increases false boss (structure of false boss sees also Fig. 1 a and Fig. 1 b, and this false boss is with the groove that is easy to clamping or hole, and groove or hole are axially uniform at false boss, can be the structures such as flat recess, cross recess);
2) utilize and to act on the false boss with the suitable frock (seeing also Fig. 2) of false boss and the end of thread and volute by cover plate assemble:
2.1) measure and record volute end face to the distance h 1(between volute and the cover plate faying face referring to Fig. 3), measure and record the cover plate large end face to the distance h 2(between volute and the cover plate faying face referring to Fig. 4);
2.2) cover plate and volute are simulated assembling, cover plate is screwed in the volute by the cover plate end of thread, cover plate and volute only are close together, simultaneously the assembling groove is simulated in the position of the large end face place volute of cover plate; The moment that adopts is not more than 10nm;
2.3) end of thread of cover plate is carried out gluing; Fill first sealing ring, then at cover plate threaded portion gluing, glue should not be too thick but even during gluing, should not make on the adhesive sealing circle.
2.4) cover plate and volute are carried out practical set, cover plate is screwed in the volute by the cover plate end of thread, twisted simulation assembling groove 0~3mm, measure simultaneously the volute end face to the distance h 3(of cover plate large end face referring to Fig. 5), until the value of h3 is not more than the difference between h1 and the h2; The moment that adopts is not more than 80nm.
3) remove false boss; Adopt the mode of turning to remove false boss from the small end face of cover plate, the direction of Cutting Force is consistent with the direction that cover plate screws during turning.
