Abstract
The utility model relates to a fixing device which is used for fatigue, stiffness, strength, stress strain tests of a front axle, in particular to a fixing device for a front axle assembly of an automobile. The fixing device comprises an upper base and a lower base which are arranged on a front axle test board, wherein a through hole is formed in the center of the upper base; a bearing bush for fixing an axle head penetrates through the through hole; the bearing bush is formed by combining two semi-conical cylinders; fixing holes are formed in two sides of the lower base; a guide groove is formed in a connection position of the lower part of the upper base and the lower base; and the fixing holes are connected with the guide groove through guide bolts. According to the fixing device, the split bearing bush is arranged in the position of the center hole of the upper base, the bearing bush can be changed rapidly to meet requirements of axle heads of different types, at the same time, mutual positions of the upper base and the lower base can be adjusted through the guide bolts, requirements of different wheel tracks are met, the form of loading a test piece into an automobile is achieved, the assembly is rapid, test data are accurate, and the test cost is saved.
Description
Technical field
This novel a kind of front axle assy fatigue, rigidity, intensity, used fixture of stress-strain tester of relating to specifically is a kind of automobile front axle assembly fixture.
Background technology
At present, when front axle assy fatigue, rigidity, intensity, stress-strain tester assembling, the employing spindle nose steps up, the slidingtype fixture.The automobile front axle camshaft stand is complex-shaped, and processing difficulties needs multistation to process in different directions, and working position has position accuracy demand each other.Because front axle assy spindle nose size, wheelspan have nothing in common with each other, each test all need be processed new fixture.So both influence the test period, strengthened experimentation cost again.
Summary of the invention
The purpose of this utility model is exactly the problem that exists for the solution prior art, and has designed the adjustable fixture that is applicable to multiple model automobile front axle assembly.
The technical solution of the utility model is: a kind of automobile front axle assembly fixture, comprise the upper bed-plate and the lower bottom base that are arranged on propons experimental test platform, described upper bed-plate center is provided with through-hole aperture, is penetrated with the fixedly bearing shell of spindle nose in the aperture, and described bearing shell is that two half-conical tubes are combined; The both sides of described lower bottom base are provided with fixing hole, and the bottom of upper bed-plate and lower bottom base junction are provided with gathering sill, connect by guide blot between fixing hole and the gathering sill.
The bottom of described lower bottom base is provided with rolling groove, is provided with the rolling cylinder that cooperatively interacts in the rolling groove.
The beneficial effects of the utility model can draw by such scheme: by the central hole with upper bed-plate split type bearing shell is set, the spindle nose that can faster quick change bearing shell satisfies different model, also regulate the mutual alignment of upper and lower base simultaneously by guide blot, satisfy the demand of different wheelspans, reach the form of simulation test piece entrucking accurately, make convenient, the test data of assembling accurately, save experimentation cost.
This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is upper bed-plate, and 2 is lower bottom base, and 3 is rolling groove, and 4 is bearing shell, and 5 are the rolling cylinder, and 6 is guide blot, and 7 is fixing hole, and 8 is gathering sill, and 9 is the aperture.
The specific embodiment:
In order to understand the utility model better, explain embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The specific embodiment: as shown in Figure 1, a kind of automobile front axle assembly fixture, comprise the upper bed-plate 1 and the lower bottom base 2 that are arranged on propons experimental test platform, described upper bed-plate 1 center is provided with through-hole aperture 9, be penetrated with the fixedly bearing shell 4 of spindle nose in the aperture 9, described bearing shell 4 is that two half-conical tubes are combined; The both sides of described lower bottom base 2 are provided with fixing hole 7, and the bottom of upper bed-plate 1 and lower bottom base 2 junctions are provided with gathering sill 8, connect by guide blot 6 between fixing hole and the gathering sill 8.The bottom of described lower bottom base 2 is provided with rolling groove 3, is provided with the rolling cylinder 5 that cooperatively interacts in the rolling groove 3.
Operating procedure is: earlier according to the front axle assy wheelspan, adjust upper bed-plate 1 and lower bottom base 2 positions, regulate the position of guide blot 6 in gathering sill 8, fixing and locking guide blot 6.
According to front axle assy spindle nose size, select correspondingly-sized bearing shell 4, bearing shell 4 steps up the front axle assy spindle nose, makes bearing shell 4 run through aperture 9, fixed axis head nut and locking.
Above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
Claims (2)
