Description
Technical field
The utility model relates to assemble device, and in particular to a kind of preproduction car suspension bushing assembly device.
Background technique
Under normal conditions, automobile power suspension system is made of three or four suspensions.Suspension is including inner assembly and outside
Component, inner assembly include inner frame and are arranged in inner frame and have the yielding rubber of crescent hole, yielding rubber and inner frame
Between be formed with through-hole, be provided with bushing in yielding rubber, outer component includes outer skeleton and the bracket that is fixed on outer skeleton, interior
Component is fitted in outer skeleton.
Traditional interim production method of suspension exemplar substantially there are two types of:
The first production method is to borrow part restructuring, that is, borrows other suspensions for referring to vehicle, will be in suspension with grinding wheel
Bracket cut off, then by itself and meet assembly demand bracket weld, be converted into the suspension exemplar for meeting assembly demand.
Since inner assembly inner wall is rubber material, grinding wheel excision bracket and the outer skeleton with inner assembly are sent out when welding with bracket
Heat is easy to burn the rubber being attached on inner assembly inner wall, causes exemplar easy to damage during test later, needs frequency
Numerous replacement refitting suspension, to delay entire project process, therefore, suspension exemplar when for sample car road test Verification Project is general
Do not use this method.
Second of production method is to borrow part restructuring assembling, that is, the part of other products is borrowed, by outer component and inner assembly
It attaches together, the method for attaching together is to be pressed into be formed in outer assembly chambeies body by inner assembly with 10T jack to suspend.Borrow part restructuring assembling is deposited
In following three disadvantages；
1 fitted position is difficult to control, when hand shaken jack, easily cause inner assembly and outer component close up during shake
Pendulum leads to part rejection to cause inner assembly easy appearance position deviation when pushing in outer component；
2 hand shaken jack can not quantify on stroke, and control is difficult, be easy to cause inner assembly and outer size of components wrong
Position；
3 there are production safety hidden danger: in inner assembly and outer component pressing process, inner assembly dislocation easily causes part fly bomb
It hurts sb.'s feelings.
Utility model content
The purpose of this utility model is just to provide a kind of preproduction car suspension bushing assembly device, and not only positioning is reliable,
Part assembly scale error is effectively reduced, is allowed to control within the scope of design tolerance, also having reduces security risk, effectively prevent
Occur in the manufacturing process of suspension part fly bomb hurt sb.'s feelings situation the advantages of.
The purpose of this utility model is achieved in that a kind of preproduction car suspension bushing assembly device, including has down
The support base of plate, support column and upper flat plate, upper flat plate and lower plate are fixed on the support columns, and lower plate upper surface is fixed with down
Die holder offers in lower die holder and takes chamber in, take in it is intracavitary be provided with annular concave platform, upper flat plate upper surface is fixed to have piston flange
Hydraulic cylinder, the piston of hydraulic cylinder passes through upper flat plate, and piston flange lower end is fixed with upper die holder, offers and serve as a contrast below upper die holder
The corresponding threaded hole in position is covered, is provided with installation bolt in threaded hole.
In the present invention, in use, the bushing that installation bolt passes through inner assembly is fixed in threaded hole, thus in making
Component is fixed below upper die holder, and outer component is fixed on the lower die seat by annular concave platform, and then Hydraulic Cylinder upper die holder is past
Under, to be pressed into the inner assembly below upper die holder is fixed in the inner frame of outer component.
By adopting the above-described technical solution, the utility model has the advantage that it is not only positioned reliably, effectively drop
Low part assembly scale error is allowed to control within the scope of design tolerance, moreover it is possible to reduce security risk, effectively prevent the system of suspension
There is the case where part fly bomb is hurted sb.'s feelings during making, moreover it is possible to reduce parts scrap rate, make the control of its qualification rate 98% with
On, also have the advantages that be applicable in the new product suspension exemplar of convenient and continuous Rapid Trial-Manufacture dimensional standard, reliable in quality.
