Description
Technical field
The present invention relates to a kind of fixture, particularly to a kind of fixture with disposable connector, belong to rock mechanics and divide
Analysis detection technique field.
Background technology
As the tensile strength of one of basic mechanical parameter, react the opposing stretching of the fragile material such as rock, concrete and become
The ability that shape is destroyed is general by its parameter value of uniaxial direct tensile measuring.Specific experiment method is: used by the sample processed
The high-strength structureal adhesives such as AB glue bond with stretching clamp, be installed in testing machine system and test after being dried completely by glue.?
In taping process, must ensure that sample is fully contacted with fixture, is firmly bonded, otherwise experimentation will occur degumming existing
As, thus cause sample not rupture, test failure.Use the sample reaching bonding standard, carry out uniaxial direct tensile according to code
Experiment.After Success in Experiment terminates, sample fracture, remove waste sample, re-start next round experiment.As it was previously stated, in order to make experiment
Success, it is necessary to ensure sample and fixture secure bond, but this mode is to remove waste sample the later stage to bring difficulty.Generally make
Dig with machinery, by methods such as fire calcining, sols, useless sample is separated with fixture.But practice display, these methods were both
Time-consuming laborious again, and efficiency is low, is difficult to fully erased to the waste sample in fixture, even destroys fixture and makes it scrap.Base
In this, we have proposed a kind of fixture with disposable connector, to improve the service efficiency of fixture.
Summary of the invention
A kind of fixture with disposable connector of offer is provided, can effectively solve background skill
Problem in art.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of fixture with disposable connector, including chuck body, described chuck body includes fixture and lower folder
Tool, described upper fixture and lower clamp are by clamp head, prominent screw thread and disposable connector composition, described upper fixture and lower clamp
Being symmetrical arranged, described clamp head one end is connected with tensile test apparatus, and described prominent threaded weld is connected in clamp head, described once
Being provided with recessed screw thread mouth inside property connector, described prominent screw thread is engaged with the recessed screw thread mouth of disposable connector, described prominent spiral shell
Stricture of vagina terminates at the internal half of disposable connector, is provided with rock sample, described rock between described upper fixture and lower clamp
Sample and disposable connector flat contact also pass through adhesives.
Further, described upper fixture is identical with lower clamp size.
Further, described prominent screw thread is positioned at the centre position of clamp head.
Further, the recessed screw thread mouth of described disposable connector is corresponding with prominent screw thread and is engaged.
Compared with prior art, there is advantages that a kind of fixture with disposable connector, pass through
The setting of disposable connector, improves the service efficiency of fixture in direct tensile test, reduces the cost of experiment, make simultaneously
Used time more original fixture is convenient, easily assembles, simple in construction, shortens the time of experiment, it is possible to obtain the most real
Test parameter.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
As Figure 1-4, a kind of fixture with disposable connector, including chuck body 1, it is characterised in that described
Chuck body includes that fixture 2 and lower clamp 3, described upper fixture 2 and lower clamp 3 are by clamp head 4, prominent screw thread 5 and once
Property connector 6 form, described upper fixture 2 and lower clamp 3 are symmetrical arranged, and described clamp head 4 one end and tensile test apparatus 7 are even
Connecing, described prominent screw thread 5 is welded in clamp head 4, and described disposable connector 6 is internal is provided with recessed screw thread mouth 8, described prominent spiral shell
Stricture of vagina 5 is engaged with the recessed screw thread mouth 8 of disposable connector 6, and described prominent screw thread 5 passes at the internal half of disposable connector 6 whole
Only, rock sample 9, described rock sample 9 and disposable connector 6 flat contact it are provided with between described upper fixture 2 and lower clamp 3
And bondd by binding agent 10, by the setting of disposable connector 6, improve the use effect of fixture in direct tensile test
Rate, reduces the cost of experiment.
Wherein, described upper fixture 2 is identical with lower clamp 3 size.
Wherein, described prominent screw thread 5 is positioned at the centre position of clamp head 4.
Wherein, the recessed screw thread mouth 8 of described disposable connector 6 is corresponding with prominent screw thread 5 and is engaged.
It should be noted that the present invention is a kind of fixture with disposable connector, during work, chuck body 1 is by upper
