Description
Technical field：
It is exactly specifically a kind of driving axle housing vertical curve fatigue tester folder the present invention relates to the laboratory holder of driving axle housing
Tool.
Background technology：
Vehicle driving axle housing vertical curve fatigue test is a kind of experiment of inspection vehicle driving axle housing endurance quality, it is desirable to watched
Being subject to 0 to 2.5 times of fully loaded load with sinus wave patters to vehicle driving axle housing on clothes control hydraulic press carries out load test.According to
Exemplar must not axially have additional force during the requirement experiment of correlation test method standard.Loading and Support Position are axle housing spring steel plate support
Between seat and the inside and outside bearing neck of both sides sleeve pipe.
Existing installation way can be slided for supported on both sides V-block in base rail slide plate, and pedestal is fixed.When experiment axle housing
Bent under loading force effect, supported on both sides clamping V-block is limited to follow by guide rail sliding plate to deform.So that
Additional moment is produced at experiment axle housing both sides clamping, the requirement of correlation test method standard is not met.
In addition the Support Position part between the inside and outside bearing neck of axle housing both sides sleeve pipe is designed as conical structure, existing clamping
Mode is fixed V-block, and it is unreliable to clamp, and can be got loose in the case where alternate load effect is tested.
Invention advantage：
The present invention is exactly to overcome deficiency of the prior art, there is provided a kind of driving axle housing vertical curve fatigue tester folder
Tool.
The present invention provides following technical scheme：
A kind of driving axle housing vertical curve fatigue test machine clamp, it includes：Guide rail sliding plate, guide rail sliding plate is provided with lower support
Plate, top board is also associated with lower support plate by bolt, it is characterised in that：In the lower support plate upper end and upper pressure
A mutual corresponding groove, V-type fixture block and lower V-type fixture block in setting, in described upper V-type fixture block are respectively equipped with plate bottom
It is equipped with and groove corresponding matching with one end of lower V-type fixture block.
On the basis of above-mentioned technical proposal, there can also be technical scheme further below：
Described groove is deep-slotted chip breaker, and is equipped with one end of described upper V-type fixture block and lower V-type fixture block corresponding with deep-slotted chip breaker
The cambered surface of cooperation.
The rolling support device with guide rail sliding plate corresponding matching, described rolling are provided with described lower support plate bottom
Support meanss include that the bottom girder being connected with lower support plate extends roller shaft at bottom girder two ends, is all provided with each roller shaft
There is a roller.
Described upper V-type fixture block and size, the profile all same of mo(u)ld bottom half fixture block.
Invention advantage：
Fixture is overall both when there is the present invention simple structure, easy to use, particularly axle housing to be bent under loading force effect
Can move horizontally can also occur angular deflection, so as to effectively avoid the generation of additional moment at clamping.Further, since upper,
The cambered surface of lower V-type fixture block is formed with deep-slotted chip breaker and is slidably matched, so upper and lower V-block can be appropriate when circular cone body region is clamped
Rotate, the taper different to adapt to cone is clamped so that the present invention can be applicable the experiment with various axle housings.
Brief description of the drawings：
Schematic diagram when Fig. 1 is present invention work；
Fig. 2 is structural representation of the invention；
Fig. 3 is stereogram of the invention.
Specific embodiment mode：
As shown in Figures 2 and 3, a kind of driving axle housing vertical curve fatigue test machine clamp, it includes：Matrix guide rail sliding plate 1, is leading
Lower support plate 2 is provided with the groove of rail slide plate 1, is provided with and the corresponding matching of guide rail sliding plate 1 in the described bottom of lower support plate 2
Rolling support device 7, described rolling support device 7 includes, the bottom girder being connected with the bottom of lower support plate 2 by bolt
7a, the roller shaft 7b of symmetrical distribution is stretched out at bottom girder 7a two ends, and one and matrix are being equipped with each roller shaft 7b
The roller 7c of the corresponding matching of guide rail sliding plate 1.
Top board 4 is set in the top of lower support plate 2, a pair bolts 3 of vertical distribution, institute are equipped with top board 4
The one end of bolt 3 stated is connected with the top of lower support plate 2, and top board 4 can be made along the axial direction of bolt 3 by adjustment bolt 3
Move up and down.
A segment distance is separated between the pair of bolt 3, and is set on the upper surface of lower support plate 2 of this interval
There is an arc groove 5, another arc groove 5 also is provided with the bottom face of top board 4, two arc grooves 5 are mutually corresponding
Distribution, and the size of two arc grooves is identical.
V-type fixture block 6 and lower V-type fixture block 6a in setting, and described V-type fixture block 6 and size, the profile of lower V-type fixture block 6a
All same.
The cambered surface with the corresponding matching of arc groove 5 is equipped with the lower end of described upper V-type fixture block 6 and lower V-type fixture block 6a
6a。
The course of work：
1st, the rolling support device below lower support plate is placed into matrix guide rail sliding plate, and so that in rolling support device
With roller matrix guide rail sliding plate formed be slidably matched.
2nd, the mo(u)ld top half fixture block of opening upwards is placed in the arc groove of lower support plate upper surface so that upper V-type fixture block
Cambered surface and arc groove form corresponding matching.
3rd, the clamping part of vehicle bridge to be tested is placed in the V-type opening of upper V-type fixture block, then side is placing on the holder portion
The V-type lower V-type fixture block that Open Side Down.
4th, place top board in the cambered surface of the lower V-type fixture block that Open Side Down so that top board lower end arc groove
With the cambered surface corresponding matching on lower V-type fixture block.Then rotate the bolt being located on top board so that top board is pushed down on down
V-type fixture block is matched for clamping tightly the clamping part of experiment vehicle bridge with upper V-type fixture block.
Operation principle：
As shown in figure 1, because the rolling support device below fixture lower support plate can level shifting in matrix guide rail sliding plate
Dynamic that angular deflection also can occur therefore, in vehicle bridge vertical curve fatigue test, there is angle in fixture in matrix guide rail sliding plate
Deflection, so as to eliminate axial additional moment.
Additionally, as shown in Fig. 2 be slidably matched because cambered surface and the deep-slotted chip breaker of upper and lower V-type fixture block are formed, so clamping
Upper and lower V-block can be rotated suitably during circular cone body region, the taper different to adapt to cone, be clamped.
