Abstract
The utility model discloses a support clamp for static torsion test and fatigue test of a long handle sliding sleeve type constant velocity universal joint assembly. The support clamp comprises a three-jaw self-centering chuck, a switch connecting piece and an L-shaped supporting frame. The three jaws of the three-jaw self-centering chuck match a bearing outer race on the universal joint assembly. The switch connecting piece is detachably fixed on the three-jaw self-centering chuck and detachably fixed on the L-shaped supporting frame. The shaft hole of the three-jaw self-centering chuck is larger than the diameter of the shaft of the long handle sliding sleeve. The diameter of the shaft holes in the switch connecting piece and the L-shaped supporting frame is larger than the bearing outside diameter in the long handle sliding sleeve. The support clamp of the utility model is capable of being used in the static torsion testing and the fatigue testing of the long handle sliding sleeve type constant velocity universal joint assembly mounted on different car chassis. The support clamp of the utility model has the characteristics of strong universality, shortened changing time of the clamp, shortened development cycle of the clamp, reduced storage space and management expense of the clamp and is remarkably reduced in development expense of the clamp on the basis of the testing accuracy.
Description
Technical field
The utility model relates to a kind of quiet fixture of turning round strength test and torsional fatigue life test that is applicable to long handle sliding sleeve class constant velocity cardan joint assembly.
Background technology
In the version of current car with constant velocity cardan joint assembly, the use of long handle sliding sleeve class constant velocity cardan joint assembly is more and more universal, in use safe and reliable for ensureing it, before formal production, need the constant velocity cardan joint assembly of its trial target to carry out the quiet performance test such as strength test and the torsional fatigue life test checking of turning round, deployment scenarios for conventional constant velocity cardan joint assembly on car load, while test, can well simulate actual vehicle condition, and for long handle sliding sleeve class constant velocity cardan joint assembly, after producing because it is formal, onboard when actual installation, there is special bracing or strutting arrangement to be fixed it, and can ensure its revolute function, therefore, in the time carrying out verification experimental verification, for the actual vehicle condition of real simulation long handle sliding sleeve, we need to increase bracing or strutting arrangement in bench test device, because the chassis of each class car is not identical, so need to develop different support fixtures in the time carrying out inhomogeneous long handle sliding sleeve test, both affected the project development cycle, cause again support fixture various, the development cost of support fixture are increased, storage space and managerial cost, and in process of the test, need repeatedly to change fixture, increase test period, reduced the work efficiency of test.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provide a kind of long handle sliding sleeve class constant velocity cardan joint assembly quiet turning round and torture test support fixture, this propclip prodigiosin be arranged on long handle sliding sleeve class constant velocity cardan joint assembly on the vehicle of all kinds of different chassis quiet turn round with torture test in use, highly versatile.
For achieving the above object, technical solution of the present utility model: quiet the turning round and torture test support fixture of a kind of long handle sliding sleeve class constant velocity cardan joint assembly, it comprises three-jaw self-centering chuck, switching web member and L-type bracing frame; Outer race on three pawls and the universal joint assembly of three-jaw self-centering chuck matches; Switching web member is removably fixed on three-jaw self-centering chuck, and is removably fixed on L-type bracing frame; Axis hole on three-jaw self-centering chuck is slightly larger than the diameter of the axle of long handle sliding sleeve, and the shaft hole diameter having on switching web member and L-type bracing frame is much larger than the diameter of the axle of long handle sliding sleeve.
The shaft hole diameter having on switching web member described above is less than the shaft hole diameter having on L-type bracing frame.Like this, in the time that the large long handle sliding sleeve class constant velocity cardan joint assembly of external diameter is done experiment, as long as change three-jaw self-centering chuck and the corresponding switching web member of large specification, need not change L-type bracing frame, save experimentation cost.
On the side of L-type bracing frame described above, be fixed with lacing wire.
The utility model adopts three pawls on three-jaw self-centering chuck to connect and fix the outer race on long handle sliding sleeve universal joint assembly, outer race is fixed, the interior ring of bearing is rotated or swings with quiet turning round with the action of fatigue rig actuator, this with on actual car, be on all four with the fixing structural principle of bracing or strutting arrangement.Because three pawls on three-jaw self-centering chuck can change and change clamping diameter with the diameter of the outer race on long handle sliding sleeve universal joint assembly, so carry out in process of the test at the long handle sliding sleeve universal joint assembly to dissimilar, without changing bracing or strutting arrangement, on the basis of warranty test accuracy, can significantly reduce the development cost of fixture, reduce the replacing time of fixture, reduce the construction cycle of fixture, reduce storage space and the managerial cost of fixture.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present embodiment comprises three-jaw self-centering chuck 2, switching web member 6 and L-type bracing frame 5.Three pawls 1 of three-jaw self-centering chuck 2 match with the outer race 13 on universal joint assembly.Switching web member 6 is fixed on three-jaw self-centering chuck 2 by screw 3 screw threads, is fixed on L-type bracing frame 5 by screw 4 screw threads.Axis hole 10 on three-jaw self-centering chuck 2 is slightly larger than the diameter of the axle 14 of long handle sliding sleeve, and on switching web member 6 and L-type bracing frame, 5 axis hole having 11,12 diameters are much larger than the diameter of the axle 14 of long handle sliding sleeve.On the side of L-type bracing frame 5, be fixed with lacing wire 9.Axis hole 11 diameters that have on switching web member 6 are less than the diameter of the axis hole 12 having on L-type bracing frame 5.7,8 threaded holes that are respectively on switching web member 6.
Embodiment described above is only preferred and example shape; not in order to limit the utility model; all within spirit of the present utility model and principle; any amendment of doing, be equal to replacement, improvement etc.; as the equal diameters of the axis hole having on the shaft hole diameter having on the web member of transferring and L-type bracing frame, on the side of L-type bracing frame, do not have within lacing wire etc. all should be included in protection domain of the present utility model.
