Technical field
The present invention relates to suspension link mounting technology field, be specifically related to a kind of top last item covering device.
Background technology
For oversize vehicle draft hitch, contained by it, between part suspension link and axle sleeve, often use the mode of interference fit
Assembling, above-mentioned fit tolerance is φ 75H7/p7.A kind of method having maturation at present, uses the leading axle loading to axle sleeve
Direction guides, and the most manually suppresses axle sleeve, thus is pounded by axle sleeve into suspension link, and this kind of method exists two drawbacks: one is
Hand labor intensity is big, and two is easily to pound partially, and the quality control of suspension link is bad.
Summary of the invention
For solving the problem that above-mentioned prior art exists, the invention provides a kind of top last item covering device, this apparatus structure
Simply, solve the most traditional pressing method labor intensity big, press-fit efficiency and press-fit problem of low quality.
Realizing the technical scheme used by above-mentioned purpose of the present invention is:
A kind of top last item covering device, including floor pan assembly, positioning seat assembly one, positioning seat assembly two, seat cylinder, jack,
Positioning apex pin, axle sleeve, fairlead and suspension link, seat cylinder, positioning seat assembly one and positioning seat assembly two are along the length of floor pan assembly
Direction is sequentially fixed on floor pan assembly, and cylinder base is ladder cylinder base, and cylinder base internal upper part is hollow hole A, and bottom is hollow hole B, in
The diameter of the emptying aperture B diameter more than hollow hole A, suspension link is provided with axle ring, retainer ring A and retainer ring B, and retainer ring A is positioned at axle
Between ring and retainer ring B, positioning apex pin is ladder round pin, and positioning apex pin is made up of thin ejector pin and thick ejector pin, and retainer ring A is sleeved on
On positioning seat assembly one, retainer ring B is sleeved on positioning seat assembly two, and one end of fairlead outer wall is provided with the groove of annular, leads
Inserting in axle ring to set, fairlead coordinates with collar gap, and fairlead sets reeded Single port down, and jack base is fixed
On floor pan assembly, jack is positioned in hollow hole B, and thick ejector pin is installed in hollow hole A, and thick ejector pin is joined with hollow hole A gap
Closing, the piston of jack contacts with the bottom of thick ejector pin, and axle sleeve is installed in hollow hole A, and the top of axle sleeve is inserted in groove, carefully
Ejector pin inserts in the bottom of axle sleeve.
Also including pressing plate, retainer ring A is sleeved on positioning seat assembly one, and is fixed by pressing plate.
Described jack is hydraulic jack.
Advantages of the present invention and beneficial effect:
This apparatus structure is simple and ingenious, on the one hand, uses jack innovatively, instead of and manually operate, from
And considerably reduce hand labor intensity；On the other hand, using fairlead and positioning apex pin to combine, asessory shaft casing pressure sets
To, improve assembling quality and efficiency of assembling.

Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, this device includes floor pan assembly 1, location to the structure of the top last item covering device that the present invention provides
Seat assembly 1, positioning seat assembly 23, seat cylinder 4, pressing plate 10, jack 5, positioning apex pin 6, axle sleeve 7, fairlead 8 and suspension link
9.Jack 5 is hydraulic jack.
Seat cylinder 4, positioning seat assembly 1 and positioning seat assembly 23 are solid successively by bolt along the length direction of floor pan assembly
It is scheduled on floor pan assembly 1.
Cylinder base 4 is ladder cylinder base, and cylinder base internal upper part is hollow hole A4.1, and bottom is hollow hole B4.2, hollow hole B4.2's
The diameter diameter more than hollow hole A4.1.
Suspension link 9 is provided with axle ring 9.1, retainer ring A9.2 and retainer ring B9.3, and retainer ring A9.2 is positioned at axle ring and fixes
Between ring B9.3, retainer ring A9.2 is sleeved on positioning seat assembly 1, and is fixed by pressing plate, and retainer ring B9.3 is sleeved on fixed
On the seat assembly 23 of position.
One end of fairlead 8 outer wall is provided with the groove 8.1 of annular, and fairlead 8 inserts in axle ring 9.1, fairlead 8 and axle ring
9.1 matched in clearance, fairlead 8 sets reeded Single port down.
Positioning apex pin 6 is ladder round pin, and positioning apex pin 6 is made up of thin ejector pin 6.1 and thick ejector pin 6.2.Jack 5 base is solid
