The specific embodiment
Below by particular specific embodiment explanation embodiment of the present utility model, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.
Refer to Fig. 1 to Fig. 2.Notice, the appended graphic structure illustrated of this specification, ratio, size etc., equal contents in order to coordinate specification to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
As shown in Figure 2, the utility model provides a kind of out star wheel stationary fixture, it comprises the first holder be connected with the out star wheel wheel shank, and the second holder be connected with out star wheel wheel head, the first holder and the second holder include connection handle 21, 31 with the clamping part 22 detachably be connected with connection handle, 32, clamping part 22, 32 comprise the atrium of accommodating out star wheel wheel shank end or out star wheel wheel head, in the atrium bottom, be provided with a through hole, the internal diameter of the through hole that the first holder is corresponding is identical with out star wheel wheel shank external diameter, the through hole internal diameter that the second holder is corresponding is taken turns between the external diameter of a bottom between out star wheel wheel shank external diameter and out star wheel.
The utility model clamps the wheel shank of out star wheel 1 by the first holder, the wheel head-clamp of the second holder and out star wheel 1 is held, during use, first the clamping part of the second holder 32 is passed from the out star wheel wheel shank, then clamping part 32 is connected with connection handle 31, namely completed the fixed clamp of the second holder, because the through hole internal diameter of the second holder is taken turns between the external diameter of a bottom between out star wheel wheel shank external diameter and out star wheel, so the limited clamping of out star wheel wheel; Then, again clamping part 22 is located on the out star wheel wheel shank, and the nut screwing clamping that will be connected with out star wheel wheel shank end, now clamping part 22 is limited on the out star wheel wheel shank, again clamping part 22 is connected with connection handle 21, has namely completed the fixed clamp of the first holder, because the internal diameter of through hole corresponding to the first holder is identical with out star wheel wheel shank external diameter, and the nut external diameter is greater than the wheel shank external diameter, so the also limited clamping of out star wheel wheel shank end.Out star wheel stationary fixture of the present utility model, it is simple in structure, easy to use, can be used as the auxiliary clamp be connected with various experimental facilities, out star wheel can be connected to the breaking test of out star wheel with tensile testing machine.
The bottom of connection handle 21,31 has the open slot of accommodating clamping part 22,32, the atrium of open slot and clamping part surrounds and forms a cavity, the wheel shank end of out star wheel 1 and wheel is spacing in this cavity, connection handle 21,31 and clamping part 22,32 are surrounded and form a cage structure.The setting of open slot can both can realize being threaded so that both connect, and also can realize by the connection of bolt or other connectors.Preferably, the inwall of open slot has internal thread, and clamping part 22,32 has external screw thread, and clamping part 22,32 is connected with connection handle 21,31 by screw thread.
Preferably, connection handle 21,31 also can directly be connected by bolt with clamping part 22,32.
For ease of clamping part is clamped on out star wheel, above-mentioned clamping part 21,31 is surrounded by least two bending members, and while using like this, the clamping part of being more convenient for is spacing on wheel shank.
The concrete use procedure of out star wheel stationary fixture of the present utility model: at first the second holder is taken turns to head-clamp by out star wheel and hold, because the through hole internal diameter that the second holder is corresponding is taken turns between the external diameter of a bottom between out star wheel wheel shank external diameter and out star wheel, while therefore using, the out star wheel wheel shank is passed in through hole, and out star wheel wheel is spacing in the atrium of clamping part 32, again clamping part 32 is connected with connection handle 31, completes the fixed clamp to out star wheel wheel head; Then, the out star wheel wheel shank is passed in the through hole of the first holder, clamping part 22 is located on the out star wheel wheel shank, the nut screwing clamping that then will be connected with out star wheel wheel shank end, now out star wheel wheel shank end is limited in the atrium of clamping part 22, and then clamping part 22 is connected with connection handle 21, namely completed the fixed clamp of out star wheel wheel shank.
During breaking test, tensile testing machine provides the pulling force for wheel shank and wheel head by the first holder and the second holder, and realization is broken the out star wheel part, does not adopt the test method of directly the out star wheel part being carried out clamping.By this out star wheel stationary fixture, not only having solved the out star wheel breaking test can't be in the problem of tensile testing machine clamping, and can better simulate out star wheel actual duty on vehicle, makes result of the test have more directiveness for the design verification of vehicle.
In sum, out star wheel stationary fixture of the present utility model, it is simple in structure, is easy to use, and can reliably out star wheel wheel shank and wheel head-clamp be held, and it can be connected with tensile testing machine, completes the breaking test to out star wheel.So the utility model has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not be used to limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
