Abstract
The utility model provides a banded product wound form anchor clamps, the fixture comprises a fixture body, be equipped with the pivot on the anchor clamps body, be equipped with the clamp plate in the pivot, the clamp plate passes through screw fixed connection with the pivot, the pivot is used for pressing from both sides case form product with the clamp plate, a pivot end connection has the hand wheel, and another end connection of pivot has a ratchet, the pivot through with ratchet complex pawl prevents gyration and locking to through the hand wheel braking, thus it is taut with banded product. The utility model has the advantages of simple and reasonable structure, convenient operation, the centre gripping problem of the appearance of banded product in carrying out the process of the test has been solved in the perfection, simultaneously, the utility model discloses can not produce mechanical damage, can not appear skidding yet, guaranteed the fracture outside anchor clamps, the test result obtains guaranteeing.
Description
Technical field
The utility model relates to a kind of fixture, refers to a kind of band-type product winding type clamping especially, for clamping banded flexible body.
Background technology
In testing machine industry, fixture is a very important ingredient, because the quality of fixture directly has influence on sample testing result, particularly some material can not clamp too tight otherwise can damage, and can not clamp again too loose otherwise there will be skidding, this is the key issue of design fixture.
Occur that a kind of new material is braid over braid on the market at present.It is woven into band-type product by chemical fibre material, described above the same of its characteristic sum in drawing process.Carry out extension test through multiple clamping apparatus, sample is not occur that skidding is exactly crush, and problem still can not solve.
Utility model content
Technical problem to be solved in the utility model, proposes a kind of band-type product winding type clamping exactly, can not produce mechanical damage, does not also occur skidding, and ensure that fracture is outside fixture, test result is guaranteed.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of band-type product winding type clamping, comprise chuck body, described chuck body is provided with rotating shaft, and described rotating shaft is provided with pressing plate, and described pressing plate is fixedly connected with by screw with rotating shaft, described rotating shaft and pressing plate are used for clamping band-type product, described rotating shaft one end is connected with handwheel, and the other end of rotating shaft is connected with ratchet, and rotating shaft prevents from turning round and stop by the retaining pawl coordinated with described ratchet, and braked by handwheel, thus band-type product is strained.
As preferably, described chuck body is also provided with guidepost, described guidepost is located at the lower position of described rotating shaft.
Principle of work of the present utility model is as follows:
Sample is flexible tape product, and first insert sample one end also with screw in compression between pressing plate and rotating shaft, snap-in force is as pretightning force, and then rotation hand wheel, makes sample in rotating shaft around Liang Quan, draws finally by guidepost.The other end of same sample too through another holder, when carrying out tension test, due to the mating reaction of ratchet and retaining pawl, rotating shaft can not be turned round, sample is constantly strained, and also constantly compresses between layers, now, due to the existence of normal pressure, sample produces friction force to be between layers enough to offset external broach, and this method does not produce mechanical damage simultaneously, does not also occur skidding, ensure that fracture is outside fixture, test result is guaranteed.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is simple and reasonable, easy to operate, perfection solves band-type product and is carrying out the clamping problem of the appearance in process of the test, meanwhile, the utility model can not produce mechanical damage, also there will not be skidding, ensure that fracture is outside fixture, test result is guaranteed.

In figure, 1-chuck body; 2-rotating shaft; 3-pressing plate; 4-screw; 5-band-type product; 6-handwheel; 7-ratchet; 8-retaining pawl; 9-guidepost.
Embodiment
For the understanding the utility model making those skilled in the art more clear and intuitive, below in conjunction with accompanying drawing, the utility model is further described.
If Fig. 1-3 is preferred embodiment of the present utility model.
A kind of band-type product winding type clamping, comprise chuck body 1, chuck body 1 is provided with rotating shaft 2, and rotating shaft 2 is provided with pressing plate 3, and pressing plate 3 is fixedly connected with by screw 4 with rotating shaft 2, rotating shaft 2 and pressing plate 3 are for clamping band-type product 5, one end of rotating shaft 2 is connected with handwheel 6, and the other end of rotating shaft 2 is connected with ratchet 7, and rotating shaft 2 prevents from turning round and stop by the retaining pawl 8 coordinated with ratchet 7, and braked by handwheel 6, thus band-type product 5 is strained.
Chuck body 1 is also provided with guidepost 9, and guidepost 9 is located at the lower position of rotating shaft 2.
Principle of work of the present utility model is as follows:
Sample is flexible tape product 5, first to be inserted sample one end between pressing plate 3 and rotating shaft 2 and to compress with screw 4, and snap-in force is as pretightning force, and then rotation hand wheel 6, makes sample in rotating shaft 2 around Liang Quan, draw finally by guidepost 9.The other end of same sample too through another holder, when carrying out tension test, due to the mating reaction of ratchet 7 and retaining pawl 8, rotating shaft 2 can not be turned round, sample is constantly strained, and also constantly compresses between layers, now, due to the existence of normal pressure, sample produces friction force to be between layers enough to offset external broach, and this method does not produce mechanical damage simultaneously, does not also occur skidding, ensure that fracture is outside fixture, test result is guaranteed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. a band-type product winding type clamping, comprise chuck body, it is characterized in that: described chuck body is provided with rotating shaft, described rotating shaft is provided with pressing plate, and described pressing plate is fixedly connected with by screw with rotating shaft, described rotating shaft and pressing plate are used for clamping band-type product, described rotating shaft one end is connected with handwheel, and the other end of rotating shaft is connected with ratchet, and rotating shaft prevents from turning round and stop by the retaining pawl coordinated with described ratchet, and braked by handwheel, thus band-type product is strained.
