Abstract
The open a kind of pole tensile sample stretching shoulder fixture of this utility model, this fixture comprises: the identical upper connector being connected with testing machine respectively and lower connector.Identical upper grip and sample lower chuck.Described outer chuck is common after being connected with upper spill spin block to be blocked in the draw-in groove being affixed to upper connector；Upper latch runs through the circular hole of spill spin block and upper outer chuck and abuts with sample.Being equipped with lower chuck in described lower connector, this lower chuck is made up of lower interior chuck and lower outer chuck；Described lower outer chuck is common after being connected with lower spill spin block to be blocked in the draw-in groove being affixed to lower connector；Lower latch runs through the circular hole of lower spill spin block and lower outer chuck and abuts with sample.This is the most novel solves the shortcoming that clamp weight is big, cannot install the machine of extending, can the fixture of convenient, fast replacing.
Description
Technical field
This utility model relates to a kind of pole sample stretching shoulder fixture.
Background technology
Yield strength refers to the maximum stress that material can bear when there is yield phenomenon.For yield phenomenon
Significantly material, yield strength is exactly the stress of yield point, material unconspicuous for yield phenomenon, with
When the limit deviation of the line relationship of stress-strain reaches setting (the usually original gauge length of 0.2%)
Stress.It is typically used as the evaluation index of solid material mechanics engineering properties, is the actually used pole of material
Limit, and existing all devices all measures this value with extensometer.Testing machine manufacturer the most now
The fixture provided is the most all hydraulically operated fixture, and volume is big, changes hard, and maximum shortcoming is precisely due to body
Long-pending big, common small sample does not installs extensometer at all, wants to install extensometer and is necessary for adding Enough long sample
Length, this can increase again the waste of material, and the when of mostly, sample is regular length, adds at all
Work not Enough long sample.
Utility model content
For solving the shortcoming that clamp weight is big, cannot install, this utility model purpose is to provide a kind of replacing
Fixture pole sample easily and efficiently stretching shoulder fixture.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of pole tensile sample stretching shoulder fixture, including: the upper connector being used in conjunction with and lower connection
Part；Being equipped with upper grip in described upper connector, this upper grip is made up of upper interior chuck and upper outer chuck；
Described outer chuck is common after being connected with upper spill spin block to be blocked in the draw-in groove being affixed to upper connector；Upper latch runs through
The circular hole of upper spill spin block and upper outer chuck abuts with sample.It is equipped with lower chuck in described lower connector, should
Lower chuck is made up of lower interior chuck and lower outer chuck；Described lower outer chuck blocks after being connected with lower spill spin block jointly
It is affixed in the draw-in groove of lower connector；Lower latch runs through the circular hole of lower spill spin block and lower outer chuck to be supported with sample
Connect.
The beneficial effects of the utility model are:
It is convenient, time saving and energy saving that structure the most of the present utility model has replacing fixture.
2. this utility model clamping sample is rapid.
3. the short sample of this utility model can also install the machine of extending, and supports variation size tensile sample.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is elaborated by reference.
As Figure 1-5, a kind of pole tensile sample stretching shoulder fixture, including: be used in conjunction with is upper
Connector 1 and lower connector 6；
Being equipped with upper grip in described upper connector 1, this upper grip is by upper interior chuck 2 and upper outer chuck 3
Composition；
Described outer chuck 3 is common after being connected with upper spill spin block 4 to be blocked in the draw-in groove being affixed to upper connector 1；
Upper latch 5 runs through the circular hole of spill spin block 4 and upper outer chuck 3 and abuts with sample.
Being equipped with lower chuck in described lower connector 6, this lower chuck is by lower interior chuck 7 and lower outer chuck 8
Composition；
Described lower outer chuck 8 is common after being connected with lower spill spin block 9 to be blocked in the draw-in groove being affixed to lower connector 6；
Lower latch 10 runs through the circular hole of lower spill spin block 9 and lower outer chuck 8 and abuts with sample.
Described upper latch 5 and lower latch 10 are designed with external screw thread.
Described upper spill spin block 4 and lower spill spin block 9 are designed with female thread.
Described outer chuck 3 is provided with the circular hole corresponding with upper spill spin block 4 screwed hole.
Described lower outer chuck 8 is provided with the circular hole corresponding with lower spill spin block 9 screwed hole.
Embodiment
As it is shown in figure 1, hand-held upper spill spin block 4, half-twist, pulling out, connected is upper
Latch 5 and upper outer chuck 3 will together be drawn out.
Load sample, regulation testing machine to correct position, spill spin block 4 in loading, upper latch 5 and upper outside
The molectron of chuck 3, upper spill spin block 4 half-twist is with locking, and sample is complete with regard to clamping.
