Description
Technical field
It is the utility model relates to a kind of indentation method test fixture, in particular to a kind of suitable for universal testing machine indentation method
Sample holding device.
Background technique
Current some small size samples will carry out Mechanics Performance Testing, and indentation method is a kind of mechanical property using tiny sample
Energy detection method obtains the load-displacement curves of sample material, according to load-displacement curves usually in dedicated indentation equipment method
Obtain mechanical property parameters.But dedicated indentation equipment is expensive, not can be carried out big load test, and universal testing machine cannot
Fixed tiny sample very well.
Summary of the invention
The purpose of this utility model is that cannot quantify, steadily move without effective fixed impression sample for universal testing machine
The problem of dynamic sample, propose a kind of fixture of the fixation that can be used in universal testing machine impression sample to be measured, can effectively fix to
Survey impression sample.
In order to solve the above-mentioned technical problem, technical solution provided by the utility model is: one kind can be used in universal test
The fixture of the fixation of machine impression sample to be measured comprising clamp base, electromagnetism mobile sliding block, sample cover board, fixing bolt, it is horizontal
Instrument；The clamp base is capable of clamping in universal testing machine, and the mobile sliding block of electromagnetism is placed in the sliding slot of clamp base, and sample to be tested is set
In on sliding block, sample cover board is placed on sample, is fixed using fixing bolt.
The electromagnetism sliding block upper and lower surface is controlled using independent coil as a further improvement of the utility model,.
The beneficial effects of the utility model are: the utility model is small in size, install convenient can fix impression sample, avoid
Sample sliding, while can quantify, steadily move sample, the upper and lower two parts of electromagnetism sliding block are respectively set electromagnetic coil, are measuring
When sliding block two parts electromagnetic coils is all powered and is completely fixed sliding block up and down, sliding block lower part solenoid current is disconnected when moving
It opens, is once again powered up fixation after mobile sliding block to target position.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawing:
In conjunction with Fig. 1-4, the specimen holder suitable for universal testing machine indentation method in the utility model, including clamp base
1, the mobile sliding block 2 of electromagnetism, sample cover board 3, fixing bolt 5, level meter 6, size scale line 7 are formed；The electromagnetism is mobile to be slided
Block 2 is slidably connected in clamp base 1, and sliding block is inserted into clamp base from sliding slot, can be free to slide in sliding slot, and sample 4 is put
It is placed in mobile 2 top of sliding block of electromagnetism, sample lid 3 is placed in 4 top of sample, and sample 4, which is fixed on electromagnetism movement by fixing bolt 5, to be slided
Block 2, level meter 6 is placed in 3 upper surface of sample cover board, for detecting specimen holder levelness, in measurement, and sliding block top electromagnetic wire
Circle 8 is powered simultaneously with sliding block lower part electromagnetic coil 9, and sliding block is fixed in clamp base, when needing sample 4 to translate, under sliding block
Portion's electromagnetic coil 9 powers off, and pushes the mobile sliding block 2 of electromagnetism to translate, observation size scale line 7 to specified position, sliding block lower part electromagnetism
Coil 9, which is re-energised, to be measured again, and test is completed sliding block top electromagnetic coil 8 and powered off, and screwed off fixing bolt 5, removed examination
The i.e. recyclable sample of sample cover board 3.
