Description
Technical field
The invention belongs to mechanical experiment equipment, relate to a kind of double-shear experiment auxiliary device, especially a kind of servicing unit when using omnipotent mechanics machine to carry out double-shear experiment.
Background technology
The research of structural heat preservation board is relatively less at home, but especially European abroad had the history of decades, relative maturity, therefore the double shear of structural heat preservation board is with reference to corresponding English mark BSEN12090 [5] standard.Existing omnipotent mechanics machine is applicable to doing the test of test block tension, resistance to compression and shearing, but when carrying out the double-shear experiment of structural heat preservation board test specimen of 100*200*50/100/150 specification, not supporting with it servicing unit, namely the laboratory holder mated with test specimen cannot be found in currently available technology, therefore, those skilled in the art urgently wish that a kind of laboratory holder of structural heat preservation board is for assistant experiment.
Summary of the invention
The object of the invention is to the shortcoming overcoming above-mentioned prior art, there is provided a kind of adjustable double-shear experiment auxiliary device, this device, by arranging upper fixing portion and bottom guide groove, can fix the test specimen of different-thickness, and not only convenient and economical, and there is general applicability.
The object of the invention is to solve by the following technical programs:
This adjustable double-shear experiment auxiliary device, comprises upper fixing portion and lower guide slot part; Described upper fixing portion comprises the large steel plate that two panels be arranged in parallel, is respectively arranged with the little steel plate that a slice is bent inwardly to 90 degree bottom the large steel plate of two panels; On the large steel plate of two panels, correspondence offers four circular holes respectively, and circular hole corresponding between the large steel plate of two panels penetrates a screw rod and fixed by nut, described little steel plate offers in order to the circular hole with guide groove partial fixing; Described channel guide section is divided and is comprised three guide rails, and every bar guide rail is furnished with 2 cover screws, and the circular hole one_to_one corresponding on described screw and little steel plate is connected.
Length and width and the thickness of above-mentioned large steel plate are respectively 400mm, 300mm and 8mm.
Length and width and the thickness of above-mentioned little steel plate are respectively 200mm, 100mm and 8mm.
Connect as one bottom above-mentioned three guide rails, be provided with the structure fixing with omnipotent mechanics tester in the bottom of guide groove part.
The present invention has following beneficial effect:
Adjustable double-shear experiment auxiliary device of the present invention is made up of upper fixing portion and bottom guide groove, the test specimen of different-thickness can be fixed, have certain general applicability, the more convenient and economic double-shear experiment problem solving larger test specimen, has filled up the blank of this respect.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Adjustable double-shear experiment auxiliary device of the present invention, comprises upper fixing portion and lower guide slot part.See Fig. 1-4: upper fixing portion comprises the large steel plate 1 that two panels be arranged in parallel, bottom the large steel plate of two panels 1, be respectively arranged with the little steel plate 2 that a slice is bent inwardly to 90 degree; On the large steel plate 1 of two panels according to such as figure position respectively correspondence offer four circular holes, circular hole corresponding between the large steel plate 1 of two panels penetrates a screw rod 3 and is fixed by nut, and little steel plate 2 offers in order to the circular hole with guide groove partial fixing.See Fig. 5-8: channel guide section is divided and comprised three guide rails 4, and every bar guide rail 4 is furnished with 2 cover screws 5, described screw 5 is connected with the circular hole one_to_one corresponding on little steel plate 2.
In preferred plan of the present invention, length and width and the thickness of large steel plate 1 are respectively 400mm, 300mm and 8mm, Circularhole diameter on large steel plate is 14mm, each hole penetrates No. 12 screw rods and is equipped with 4 nuts, as shown in Figure 1, in a position for being welded, b, c, d position is adjustable, so just can the length L of regulating device, for the test specimen of different-thickness.Length and width and the thickness of little steel plate 2 are respectively 200mm, 100mm and 8mm.
Connect as one bottom three guide rails 4 of the present invention, be provided with the fixed sturcture 6 be connected with omnipotent mechanics tester in the bottom of guide groove part.
The present invention in use, the bottom of guide groove part is connected with omnipotent mechanics tester, 3 guide rails are arranged as shown in the figure at top, every bar guide rail is furnished with 2 cover screws, during experiment, clings one block of T-shaped plate and omnipotent mechanical test instrument top is fixed in the middle of 2 standard specimens, the plank of 1 surface area 400*300 is glued on 2 standard specimen surfaces respectively, punch position is identical with iron plate with size, penetrates screw internal fixtion, to reach the fixing effect of test specimen.And is alignd with guide groove in the hole of experimental provision bottom, fix with screw and omnipotent mechanics tester bottom, middle pad with rubber slab in case on-slip moves.
In sum, the present invention the most important thing is test specimen and bottom guide groove are completely fixed, so bent two panels steel disc on base, perforating on steel disc, and be completely fixed extremely by screw and base adjustability, base can be fixed by the web member of lower bands circular hole and universal testing machine again, just completes bottom and fixes.Top takes one piece of T-shaped plate holder on the top of universal testing machine.
