Abstract

The utility model relates to a brittle material compression test anchor clamps, specially adapted brittle material compression strength is experimental. The utility model discloses a form by upper and lower centering rod, upper and lower backup pad, upper and lower briquetting and spheric seat, lower support rod and connecting by spheric seat between the briquetting down wherein, spheric seat can realize down that the small slope of briquetting is in order to guarantee specimen surface and last briquetting surface parallel to solve the small deviation problem between the unable compensation sample of compression dish anchor clamps and the clamp plate depth of parallelism. The utility model discloses a be applicable to and install and use on ordinary material test machine, can realize that compression strength is experimental, and have simple structure, in the aspect of the use, characteristics such as easy dismouting.

Description

A kind of fragile material compression test fixture
Technical field
This utility model belongs to experiment appliance exploitation manufacture field, is particularly used for fragile material compression test Fixture.
Background technology
Material Testing Machine carries out typically requiring during compression test configuration compression clamp and fixes sample, and for Fixture used by different materials and experiment purpose is the most different.Patent CN 203798673 U provides A kind of high temperature compressed fixture, solves the test problem of material at high temperature compression performance index;Patent CN 204461890U provides a kind of full support thin plate compression clamp, overcomes work in the middle of the sample of conventional brace The section of work is without effectively supporting the problem that buckling failure easily occurs;Patent CN 204422329 U provides a kind of machine Compression clamp on tool formula tensile test machine, solves on mechanical type tensile creep endurance testing machine not The problem that can be compressed creep test.And for this nonmetal fragile material of refractory material, during test by Cannot compensate the little deviation between sample compression face and the pressing plate depth of parallelism in compact disk fixture, specimen surface is subject to Power is uneven, makes sample partially damaged, causes test data fluctuation big, it is impossible to reflect refractory material Actual strength, success of the test rate is relatively low.Had no by inquiry and press from both sides about the compression test for fragile material The design invention of tool, is thus badly in need of a kind of fragile material compression clamp and solves the problems referred to above.
Summary of the invention
For the problems referred to above, this utility model provides a kind of fragile material compression test fixture, solves compression Plate clamp cannot compensate the problem of the little deviation between sample compression face and the pressing plate depth of parallelism, by design system Make and be connected with Material Testing Machine, it is achieved refractory material compressive resistance is tested, and has higher practical value.
Unresolved above-mentioned technical problem, the technical solution adopted in the utility model:
A kind of fragile material compression test fixture, mainly by upper centering rod, lower centering rod, upper backup pad, under Gripper shoe, upper holder block, lower lock block and spheric seat composition;Wherein go up centering rod, lower centering rod and upper backup pad, Lower supporting plate is threadably secured connection;Upper holder block is threadably secured with upper backup pad and is connected;Lower supporting plate And connected by spheric seat between lower lock block, lower lock block is threadably secured connection spheric seat.
Further, the upper centering rod of described fragile material compression test fixture and the shape specification of lower centering rod Match with grip of testing machine.
Further, the described upper holder block of fragile material compression test fixture, lower lock block are provided with center cast line, It is easy to sample centering.
Further, the lower supporting plate of described fragile material compression test fixture is provided with spherical groove, its size with Spheric seat matches, spheric seat in lower supporting plate spherical groove can minute movement, regulate lower lock block angle of inclination, Parallel with upper holder block surface with specimen surface during guarantee test.
Further, each several part of described fragile material compression test fixture all uses mould steel.
Due to the fact that and have employed above technical scheme, be allowed to compared with prior art that there is following useful effect Really:
Present clip simple in construction, manufactures and easy to use, it is easy to dismounting, can be at material testers On install and use.Fixture is provided with center cast line, it is simple to sample centering.By using spheric seat design to make Energy automatic fine tuning contact plane during sample stress, it is ensured that sample uniform stressed, improves data accuracy.
Accompanying drawing illustrates:
The clamp structure schematic diagram that Fig. 1 provides for the present invention,
Wherein, right under the upper centering rod of 1-, 2-upper backup pad, 3 upper holder blocks, 4-lower supporting plate, 5-spheric seat, 6- Middle bar, 7-lower lock block;
Fig. 2 is the stress-strain curve diagram of sample compression test.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further elaborated:
Refractory material compression test fixture as shown in Figure 1, mainly by upper centering rod 1, lower centering rod 6, Upper backup pad 2, lower supporting plate 4, upper holder block 3, lower lock block 7 and composition, fixture each several part all uses mould Steel.
Wherein go up centering rod 1, lower centering rod 6 is threadably secured is connected with upper backup pad 2, lower supporting plate 4; Upper holder block 3 is threadably secured with upper backup pad 2 and is connected;By spherical between lower supporting plate 4 and lower lock block 7 Seat 5 connects, and lower lock block 7 is threadably secured connection spheric seat 5.
Upper centering rod 1 and lower centering rod 6 are separately mounted on testing machine in lower clamp, shape specification and test Machine clamp matches.Upper holder block 3, lower lock block 7 are provided with center cast line, it is simple to sample centering.
Lower supporting plate 4 is provided with spherical groove, and its size matches with spheric seat 5, and spheric seat 5 is at lower supporting plate 4 In spherical groove can minute movement, regulate lower lock block 7 angle of inclination, with specimen surface during guarantee test and upper pressure Block 3 surface is parallel.Add a little lubricating oil on spheric seat 5 and put into the spherical groove of lower supporting plate 4, to be measured The center cast line of upper holder block 3 and lower lock block 7 put into by sample, and centering also arranges test parameters and tests. Upper holder block 3 and lower lock block 7 can change different size according to sample size.The stress of sample compression test should Varied curve, is shown in Fig. 2.
This utility model can also have other numerous embodiments, but is not carrying on the back the feelings of spirit and essence thereof Under condition, those skilled in the art are when making various corresponding change and deformation according to the present invention, but these phases The change answered and deformation all should belong to the protection domain of appended claims of the invention.
