Description
Technical field
The utility model relates to vehicle shock absorber performance test facility technology field, especially a kind of damper performance test
Platform automatic aligning fixes device.
Background technique
Damper is the important component in automobile, it is directly related to the comfort and stability of vehicle driving, due to subtracting
The particularity of vibration device working environment, the Stability and dependability of damper are very important.Therefore, in the production of damper
In, it needs for the damper after assembling to be fixed on damper test stand, to the damping characteristic of damper, damping force waveform, rub
It wipes the performances such as power to be tested, and therefrom obtains test data.Currently, the fixation device that existing damper test stand uses is deposited
In following defect, first is that poor universality since damper has plurality of specifications size, needs mating in the performance test
Thus the more sleeve fixture mechanisms for producing corresponding specification size lead to the at high cost of detection, and also add the loss wave of material
Take.Second is that then need to shut down and dismantle current fixation devices when testing in test the damper of different size if necessary, then
The corresponding matched fixed device of replacement, operation are not only cumbersome, time-consuming but also long.Third is that for the purpose of fastening, fixation device used
With the end Hard link of damper, the radial force generated when test is caused to directly influence the accuracy of test data.Fourth is that existing
There is fixed device by long term test operation, fatigue effect occurs in the metals connection fixture such as bolt, leads to fixed device stress
Uneven deformation or damage then needs replacing entire fixed device, takes time and effort and equally increase the loss waste of material.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, providing that a kind of versatility is good, can adjust automatically
The heart eliminates radial force, improves the fixed device of damper performance test stand automatic aligning of test data accuracy.
For realize the purpose of this utility model used by technical solution be: the device by upper holder, fixed block, hold out against
Bolt and holding nut composition, wherein upper holder is concave-shaped openings structure, and top is fixedly connected with testing stand, and lower part is opened
Mouth two sides position is opposite to be installed there are two puller bolt and the back nut being cooperatively connected with puller bolt, and fixed block is located at upper
The middle part of fixed frame opening is embedded with universal self-aligning bearing in the centre of fixed block, which faces out convex
Edge is connected with two puller bolts installed on upper holder respectively, and fixed block is each of prism structure, fixed block
The screw hole for mating connection different size damper is equipped in circumferential lateral surface.
The circumferential lateral surface quantity of the fixed block is 6 faces or 8 faces or 10 faces.
According to the fixed device of damper performance test stand automatic aligning made of above scheme, structure is simple, low in cost,
Versatility is good, can meet the needs of more specification dampers by the fixed block of setting, effective solution test different size
Matching problem is tested when damper.And when the damper or fixed device damage for testing different size need replacing, it is not necessarily to
Dismounting and change entirely fixes device, both time saving and energy saving, in turn avoids material loss waste.Meanwhile cleverly at fixed block center
Design enclose universal self-aligning bearing, by with clamping engagement, not only meet the needs of fastening, and can effectively eliminate
Thus the radial force generated when test greatly improves the accuracy of test data.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of fixed block in Fig. 1.
Specific embodiment
The following further describes the utility model with specific embodiments.
Referring to Fig. 1, Fig. 2, the fixed device of the damper performance test stand automatic aligning of the utility model, the device is by upper solid
Determine frame 1, fixed block 4, puller bolt 2 and holding nut 3 form, wherein upper holder 1 is concave-shaped openings structure, top with
Testing stand is fixedly connected, and lower openings two sides position is opposite to be installed there are two puller bolt 2 and be cooperatively connected with puller bolt 2
Back nut 3, fixed block 4 is located at the middle part of 1 opening of upper holder, is embedded with universal tune in the centre of fixed block 4
Mandrel holds 4-2, and the flange which faces out is connected with two puller bolts 2 installed on upper holder 1 respectively,
Fixed block 4 is prism structure, and the circumferential lateral surface quantity of fixed block 4 is 6 faces or 8 faces or 10 faces, is all provided in each circumferential lateral surface
There is the screw hole 4-1 for mating connection different size damper.
When test, 6 bottom of damper is fixed on testing stand by conventional fixed form, then by 6 top of damper
The screw hole 4-1 that size is corresponded on connecting rod and the fixed block 4 of the fixation device is threadedly engaged connection fastening, tightens 1 liang of upper holder
The puller bolt 2 of side can start to test.Generated radial force in test, by the universal self-aligning bearing 4- on fixed block 4
2 automatic aligning and eliminate, can be improved the accuracy of test data.Furthermore, it is desirable to damper of different specifications and sizes is replaced,
Without shutdown, fixed block 4 is rotated, the screw hole 4-1 for finding corresponding damper size matches with 6 upper links of damper vertically downward
Connection is closed, trystate can be again introduced into.Holding nut 3 plays the role of supporting stress, when fixed device needs repairing
When replacement, it is only necessary to back nut 3 is replaced, it is more convenient quick.Device effective solution different size size damper
The fixed matching problem of test, not only versatility is good, but also easy to operate, it is thus also avoided that material loss waste.
