Description

A kind of assembling fixture

Technical field

The utility model relates to a kind of assembling fixture, is used for the suspend rubber bushing of part of automobile is pressed in the welding support, belongs to auto parts and components apparatus for assembling technical field.

Background technology

Along with developing of automobile industry.Rubber bushing is pressed into the vibration damping field that structure in the welding support is used to automobile more and more.Rubber gum cover I as shown in Figure 1 is pressed among as shown in Figure 2 the welding support II through the location of assembling fixture in hydraulic pressure group installation.For the position after improving rubber bushing and being pressed into improve operator's operating efficiency, be pressed into again after often needing the rubber bushing that is not pressed into had good positioning, and need be pressed into the back operator and take out very like a cork.But present assembling fixture can not meet the demands.

Summary of the invention

The purpose of this utility model provides a kind of assembling quality that improves product, improve operative employee's operating efficiency and be convenient to the assembling fixture of assembling fixture maintenance.

In order to achieve the above object, the technical solution of the utility model provides a kind of assembling fixture and comprises top assembly and lower component, it is characterized in that, the top assembly comprises upper plate, on the bottom surface, middle part of upper plate, be provided with the lining briquetting, be respectively equipped with the guide pillar limited block in the both sides, bottom surface of upper plate;

Lower component comprises lower shoe, end face both sides at lower shoe are respectively equipped with the guide pin bushing limited block, end face middle part at lower shoe is provided with the spring limited post, one end of spring is enclosed within outside the spring limited post, the other end is located in the stuck-module and with mobile module and is connected, mobile module is located at the top of stuck-module, is provided with the support limited post in the both sides of mobile module, and mobile module is provided with the lining reference column.

The utility model utilizes the elastic force of spring with the product resilience that presses, and guide pillar limited block and guide pin bushing limited block play guiding and position-limiting action in assembling process, prevents that lining from pressing askew and product is crossed compressive strain.

Advantage of the present utility model is as follows:

1, the product size after the assembling is highly stable, produces the symmetry tolerance that cover is pressed in the welding support and is ± 0.1mm, and the package size deviation guarantees consistency of product well at ± 0.2mm, and process capability index Cpk can reach more than 1.67;

2, production efficiency is very high: can reach 1500/8 hours, welding support is put in the anchor clamps at an easy rate, and lining also can easily be put into, and mainly is also can easily take out after product presses.Also eliminate product colliding with in assembling process, reduced follow-up touch-up paint operation;

3, easy to operate: as to have alleviated the anchor clamps overall weight, be convenient to the operator and on hydraulic press, adjust anchor clamps, adjusted anchor clamps and only need put into welding support and lining afterwards, pressed start button, again product has been taken out such simple working;

4, easy to maintenance: because all be to connect with bolt, be easy to dismounting, concrete which part has damage just to pull down which part of direct repairing.

The specific embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

As shown in Figure 3, the utility model provides a kind of assembling fixture, comprises top assembly A and lower component B, connects all to be connected by the standard specification bolt, intactly is installed in above the hydraulic pressure group installation.

As shown in Figure 4, the top assembly comprises upper plate 11, is provided with lining briquetting 10 on the bottom surface, middle part of upper plate 11, is respectively equipped with guide pillar limited block 9 in the both sides, bottom surface of upper plate 11;

As Fig. 5 and shown in Figure 6, lower component comprises lower shoe 1, end face both sides at lower shoe 1 are respectively equipped with guide pin bushing limited block 2, end face middle part at lower shoe 1 is provided with spring limited post 3, one end of spring 4 is enclosed within outside the spring limited post 3, and the other end is located in the stuck-module 5 and with mobile module 6 and is connected, and mobile module 6 is located at the top of stuck-module 5, be provided with support limited post 7 in the both sides of mobile module 6, mobile module 6 is provided with lining reference column 8.

The operation principle of this assembling fixture is: whole anchor clamps are moved in the hydraulic pressure group installation, be connected with the hydraulic pressure group installation with lower shoe 1 with assembling fixture upper plate 11; The position that is used for adjusting assembling fixture by guide pillar limited block 9 and guide pin bushing limited block 2; Installation is put into welding support earlier on stuck-module 5 after adjusting, and utilizes welding support reference column 7 and mobile module 6 on the stuck-module 5 fully welding support to be reserved the position; Again lining is put into mobile module 6, utilized the lining reference column 8 on the mobile module 6 that lining is had good positioning equally.When starting the hydraulic pressure kludge, drive assembling fixture upper plate 11 and move downward, cause lining briquetting 10 that lining is pressed in the welding support; After being under pressure, spring 4 under the whole process mobile module is compressed; Treat that lining is pressed onto fully that the hydraulic pressure group installation drives the position that assembling fixture upper plate 11 turns back to beginning behind the qualified position, these process medi-spring 4 pressures slowly reduce and resilience, thereby the product that assembles is slowly bounce back into the position of putting lining before, entire product has broken away from the restriction of the reference column 7 on the stuck-module 5, the operative employee just can easily take out the product that assembles, and so far the entire product assembling process is all finished.Lining briquetting 10 in the utility model, stuck-module 5 and mobile module 6 can be changed according to the positioning requirements and the size of different product, and other part is general, and versatility is more intense like this, can reduce the manufacturing cost of anchor clamps, also helps the management of anchor clamps.
