Abstract
The invention discloses a fixture for the tensile test of a tensile machine. The fixture comprises a support, threaded rods and splints, wherein two side plates of the support are provided with threaded through holes I; the threaded rods are inserted into the threaded through holes I; the splints are perpendicularly fixed on one ends, positioned in the support, of the threaded rods; each splint is provided with at least two threaded through holes II, and at least three clamping grooves matched with the fixture are arranged, and are of multiple types; clamping grooves matched with different types of workpieces are selected, so that the problem that one fixture can only be used for fixing one type of workpieces is avoided, and a workpiece is prevented from separating away from the fixture in the tensile performance testing process.
Description
Technical field
The present invention relates to mechanical field, particularly, relate to a kind of fixture for puller system tension test.
Background technology
for some workpiece, need to test its tensile property, in laboratory, industrial circle, puller system is the tensile property for test piece of commonly using, to accurately test out the tensile property of workpiece, key is to be fixed, fixture is for the common tool of fixation workpiece, at present, a puller system is generally only furnished with a kind of fixture, and fixture can only be used for the workpiece of fixing same type, like this for the test of dissimilar workpiece with regard to handy different puller system, make like this cost improve, can not utilize fully resource, make the wasting of resources.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of fixture for puller system tension test, the problem that can only fix same type workpiece to overcome a kind of fixture of prior art.
The present invention addresses the above problem adopted technical scheme: a kind of fixture for puller system tension test, comprise bearing, threaded rod, clamping plate, on bearing biside plate, offer tapped through hole I, threaded rod inserts in tapped through hole I, clamping plate are vertically fixed on threaded rod one end in bearing, on each clamping plate, at least offer 2 tapped through hole II, be provided with at least three kind draw-in grooves supporting with fixture, on draw-in groove, be provided with the tapped through hole III coordinating with tapped through hole II, the available screw coordinating with tapped through hole II, tapped through hole III is fixed on draw-in groove on clamping plate.By tapped through hole II is set on clamping plate, can select suitable draw-in groove according to the concrete shape of institute's test piece, draw-in groove is fixed with screw, because draw-in groove coordinates with tested workpiece, so well fixation workpiece, the workpiece of test different types only need be changed corresponding draw-in groove, so, has avoided a kind of fixture can only fix the problem of same type workpiece.
Further, draw-in groove has various ways, as square structure, arc groove structure, oat tail groove structure etc.The workpiece that different structure is corresponding dissimilar, and according to the concrete material of dissimilar workpiece, the draw-in groove of unlike material can be set, in the hope of protecting to greatest extent workpiece not by clamp wear.
Further, tapped through hole III is at least provided with 2 on each draw-in groove.Multiple tapped through hole III be arranged so that draw-in groove is fixing more firm on clamping plate, therefore can better fixation workpiece, avoided workpiece to depart from fixture in tensile property test process.
To sum up, the invention has the beneficial effects as follows:
1, avoided a kind of fixture can only fix the problem of same type workpiece.
2, avoided workpiece to depart from fixture in tensile property test process.
Brief description of the drawings
Fig. 1 is the structural representation of fixture.
Mark and corresponding parts title in accompanying drawing:
1-bearing; 2-tapped through hole I; 3-threaded rod; 4-clamping plate.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is done to detailed description further, but embodiments of the present invention are not limited to this.
Embodiment: as shown in Figure 1, a kind of fixture for puller system tension test, comprise bearing 1, threaded rod 3, clamping plate 4, on bearing 1 biside plate, offer tapped through hole I 2, threaded rod 3 inserts in tapped through hole I 2, clamping plate 4 are vertically fixed on threaded rod 3 one end in bearing 1, on each clamping plate 4, at least offer 2 tapped through hole II, be provided with at least three kind draw-in grooves supporting with fixture, on draw-in groove, be provided with the tapped through hole III coordinating with tapped through hole II, available and tapped through hole II, the screw that tapped through hole III coordinates is fixed on draw-in groove on clamping plate 4, tapped through hole III is at least provided with 2 on each draw-in groove, draw-in groove has various ways, as square structure, arc groove structure, oat tail groove structure etc., the workpiece that different structure is corresponding dissimilar, and according to the concrete material of dissimilar workpiece, the draw-in groove of unlike material can be set.One end of workpiece is fixed in the draw-in groove on fixture, and the other end is fixed in the draw-in groove of another fixture, and two fixtures are same, between two fixtures, connects with spring, so, can carry out Erichsen test to workpiece.
As mentioned above, can realize preferably the present invention.
