Technical field
The present invention relates to a kind of tester, particularly relate to a kind of gasket material high-temerature creep tester.
Background technology
This invention is the Measurement accuracy task of creep compliance when utilizing variation bolt, clock gauge, temperature-controlled box to complete encapsulant high temperature (90 DEG C) that require in national standard.At present, the high-temerature creep tester of domestic application is all import equipment.Device structure is complicated, expensive.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, easy to operate, measure gasket material high-temerature creep tester accurately, the Measurement accuracy task of creep compliance when this tester can complete encapsulant high temperature (90 DEG C) that require in national standard.
The present invention realizes like this, a kind of gasket material high-temerature creep tester, it comprises measurement clock gauge dial plate, dial gauge frame, clock gauge fixed cover, fastening bolt, gauge outfit measured by clock gauge, positioning core axle, hollow bolt, pressurizing nut, top board, tested encapsulant, lower platen, fixing rivet, it is characterized in that the bottom of hollow bolt is provided with positioning end, tested encapsulant upper, lower end is respectively equipped with top board and lower platen, top board and lower platen are fixed by pressurizing nut, exert pressure, the interior sky of described hollow bolt is vertically equipped with positioning core axle, the bottom of positioning core axle is fixed on hollow bolt by fixing rivet, gauge outfit is measured near clock gauge in the top of positioning core axle, clock gauge is measured gauge outfit and is connected measurement clock gauge by dial gauge frame, described dial gauge frame is fixed on the top of hollow bolt by clock gauge fixed cover and fixes with fastening bolt.
Technique effect of the present invention is: structure is simple, easy to operate, measurement is accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In the drawings, 1, measurement clock gauge dial plate 2, dial gauge frame 3, clock gauge fixed cover 4, fastening bolt 5, clock gauge measure gauge outfit 6, positioning core axle 7, hollow bolt 8, pressurizing nut 9, top board 10, tested encapsulant 11, lower platen 12, fixing rivet.
Embodiment
As shown in Figure 1, the present invention realizes like this, the bottom of hollow bolt 7 is provided with positioning end, tested encapsulant 10 is through hollow bolt 7, on it, lower end is respectively equipped with top board 9 and lower platen 11, top board 9 and lower platen 11 are fixed by pressurizing nut 8, pressurization, the interior sky of described hollow bolt 7 is vertically connected with positioning core axle 6, the bottom of positioning core axle 6 is fixed on hollow bolt 7 by fixing rivet 12, gauge outfit 5 is measured near clock gauge in the top of positioning core axle 6, dial gauge frame 2 connects measurement clock gauge reading dial 1, described dial gauge frame 2 is fixed on the top of hollow bolt 7 by clock gauge fixed cover 3 and fixes with fastening bolt 4.
Concrete measuring method is: tested encapsulant (10) is put between the top board (9) of hollow bolt (7) lower end and lower platen (11), applies standard axle pressure by pressurizing nut (8) to tested encapsulant; The pressure of regulation is controlled by clock gauge reading dial 1.Because tested encapsulant can make hollow bolt produce small elastic deformation to the reacting force of pressurizing nut, namely hollow bolt has minute elongation.And the positioning core axle (6) in hollow bolt is by fixing rivet (12) and hollow bolt riveting one surely, because positioning core axle (6) not stressing so do not extend.Therefore, between positioning core axle (6) and hollow bolt (7), just create the relative shift produced due to applying standard axle pressure, the clock gauge that this micro-displacement amount ⊿ L is fixed on hollow bolt top measures.So, pressure size, distortion size can be grasped accurately, easily by this tester.
After tested encapsulant is loaded on regulation axle power, the compression deformation L of record clock gauge display
0.Unclamp fastening bolt 4, take off measurement clock gauge, the tested encapsulant of exerting pressure is put into temperature-controlled box, maintain the standard the 90 DEG C of hot environments and time that require, more naturally cool under putting into normal temperature environment.Then, reinstall measurement clock gauge, unclamp pressurizing nut (8), the recoverable force L of clock gauge display can be recorded
1.Due to material creep, distortion can not recover completely.Then:
⊿ δ=L
0-L
1it is exactly the creep compliance of tested encapsulant.
The high-temerature creep of the larger then material of ⊿ δ is larger, and elevated-temperature seal performance is poorer, completes test process thus.
Because measurement clock gauge is fixed on hollow bolt by clock gauge fixed cover (3), fastening bolt (4), and accurately and reliably; Easy disassembly again.Therefore, this type of test problem can be solved well.
