Technical Field

The invention relates to the field of aviation part assembly, in particular to an auxiliary mounting device for an assembly fixture and a construction method.

Background

The assembly jig part shown in fig. 1 comprises a part to be assembled and a heating part sleeved on the outer side of the part to be assembled, the monthly demand is large, a complaint of owing is frequently issued abroad, the cooperation relationship between companies at home and abroad is influenced by the owing of the part, and other introduced items of the company are not affected well. In the existing part assembly, a person with strong assembly technical capability is required for assembly. Because the parts are assembled in an interference fit mode, the interference magnitude is 0.2mm, and in addition, the roundness of the parts to be assembled is large, the heating parts are taken out of the heating furnace and cooled quickly, and the assembling difficulty is greatly increased.

Before the assembly operating personnel need with the part heating, the part is end flat for can't guaranteeing when the assembly of its assembly degree of difficulty, in case the part takes place the slope then the assembly part can the card put in heating the part, assembly failure leads to following consequence this moment: first, the part is not bottomed; second, the parts are broken by striking with a wood hammer until fully assembled. The failure rate reaches 40% through statistics, the rejection rate is 10%, and therefore part assembly is always the production bottleneck of the part workshop section, the assembly efficiency is low, and meanwhile, the costs of manpower, funds and the like are wasted.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides an auxiliary mounting device for an assembly fixture and a construction method, and the specific technical scheme is as follows:

the utility model provides an assembly fixture auxiliary erection device, includes the base, sets up guide post and the cover on the base and establish the guide pin bushing in the guide post outside and with guide post sliding connection, is equipped with the storage tank on the base and lie in the guide post outside, and one side that the guide post was kept away from to the guide pin bushing is equipped with multiunit elasticity steel ball.

According to the invention, an operator heats a heating part and then places the heating part in the accommodating groove on the base, places the guide sleeve into the part to be assembled, fixes the part to be assembled outside the guide sleeve by using the elastic steel ball, and then presses the guide sleeve into the accommodating groove to assemble the heating part and the part to be assembled.

Preferably, the elastic steel balls are connected with the guide sleeve in a sliding mode and are uniformly distributed on the outer side of the guide sleeve.

According to the invention, the elastic steel ball is in sliding connection with the guide sleeve, so that when the guide sleeve is placed in a part to be assembled, the elastic steel pipe can fix the part to be assembled outside the guide sleeve by using the elasticity of the elastic steel pipe. Meanwhile, the elastic steel balls are uniformly distributed on the outer side of the guide sleeve, so that the stress of the part to be assembled is uniform, and the problems of local displacement, falling and the like in the assembling process can be avoided.

Preferably, a plurality of groups of handles are arranged on the guide sleeve.

According to the invention, the guide sleeve with heavier weight can be lifted by an operator in the assembling process through the handle arranged on the guide sleeve, so that the convenience and the practicability of the invention are improved.

Preferably, the shape of the accommodating groove is annular.

According to the invention, the annular accommodating groove is adopted, so that the heating part is placed in the accommodating groove after being heated without sliding and the like, and the heating part and the part to be assembled can be assembled conveniently by an operator.

A construction method of an auxiliary installation device of an assembly fixture sequentially comprises the following steps:

(S1): heating the heating part in a heating furnace, taking out the heating part, and quickly placing the heating part in a containing groove in a base;

(S2): placing the guide sleeve into the part to be assembled, and fixing the part to be assembled by the elastic steel ball;

(S3): the guide sleeve is lifted by the handle and sleeved outside the guide column, and then the guide sleeve is pressed into the accommodating groove, so that the heating part and the part to be assembled are assembled;

(S4): and taking the guide sleeve out of the guide column, taking the assembled part out of the accommodating groove, and checking and measuring the gap between the part to be assembled and the heated part by using a feeler gauge.

Preferably, the heated part in step (S1) should be heated in a furnace to a size that is a clearance fit with the size of the part to be assembled.

According to the invention, the heating part is heated to the size which is in clearance fit with the size of the part to be assembled, so that the part to be assembled can be easily put into the heating part in the assembling process, the assembling difficulty is reduced, and the assembling efficiency is further improved.

Preferably, in the step (S3), the operator presses the guide bush into the accommodating groove to maintain the horizontal posture.

According to the invention, when an operator presses the guide sleeve into the accommodating groove, the horizontal posture is kept, so that a part to be assembled vertically enters the heating part, and the assembling requirement is met.

Preferably, the gap criterion between the part to be assembled and the heated part in the step (S4) is zero.

According to the invention, the heating part and the part to be assembled are in interference fit, and the interference magnitude is 0.2mm, so that the clearance standard between the part to be assembled and the heating part is set to be zero, and the detection is convenient for an operator.

The invention has the following beneficial effects:

according to the invention, an operator heats a heating part and then places the heating part in the accommodating groove on the base, places the guide sleeve into the part to be assembled, fixes the part to be assembled outside the guide sleeve by using the elastic steel ball, and then presses the guide sleeve into the accommodating groove to assemble the heating part and the part to be assembled. The invention skillfully utilizes the elastic steel ball to ensure that the part to be assembled is efficiently loaded into the guide sleeve without being influenced by roundness and size, and the precision fit between the guide column and the guide sleeve is selected to control the inclination of the part, so that the part is not influenced by the inclination of human factors, and the assembly requirement is further met. The invention has higher stability and high efficiency, improves the assembly efficiency and the assembly qualification rate, reduces the rejection rate of parts and the rework and repair rate of parts, has simple operation and greatly saves the production cost of the parts.
