Description
Technical field
It the utility model is related to the clamping device of steel wire tension test, and in particular to a kind of minor diameter steel wire tension test
The middle clamping claw used.
Background technology
In steel wire rope production, it is desirable to breaking tensile test is done on material stretch test machine, to obtain the anti-of material
The technical parameters such as tensile strength, yield strength, elongation percentage, residual stress, modulus of elasticity.
The fixture that traditional cupping machine is used for clamped wire both ends typically uses standard flat pliers mouth or full-height tooth chip
Fixture, during clamped wire sample, effective holding area is smaller, easily causes steel wire test and is skidded in jaw, tests steel wire
The gripping step of process repeats, and reduces test efficiency, in addition, effectively holding area is smaller, easily steel wire test is formed
Larger compression, easily cause and test the clamped position generation damage of steel wire sample, cause to test the disconnected jaw of steel wire sample, draw
Play unnecessary invalid experiment.Meanwhile the abrasion of jaw are also larger.Obviously, when being tested using the fixture of prior art, deposit
It is inaccurate in test data, it is necessary to retrial of resampling, tedious process, the shortcomings that test efficiency is low.
The content of the invention
The purpose of this utility model stably may be used in view of the deficienciess of the prior art, providing a kind of clamped wire sample
Lean on, change convenient disassembly, can effective lifting test operating efficiency, save the replaceable pincers of minor diameter steel wire tension test of manpower
Mouthful.
To achieve the above object, the utility model uses following technical scheme：
A kind of replaceable jaw of minor diameter steel wire tension test, including symmetrically arranged left clamp body, right clamp body, it is special
Sign is：Jaw mounting groove is respectively equipped with the opposite clamping face of described left clamp body, right clamp body, is provided with jaw mounting groove
Jaw, the clamping working surface of jaw are provided with crosswise serration.
In the utility model, the left clamp body, a side end face of right clamp body are respectively equipped with jaw fixing screw hole, pincers
Mouth fixing screw hole is connected with jaw mounting groove, and housing screw is screwed into jaw fixing screw hole can be pressed in jaw on pincers
In mouth mounting groove.
Further, another side relative with clamping working surface on the jaw is also equipped with crosswise serration.
Further, the groove set on the jaw is in 90 ° of cross arrangements.
To improve service life, the jaw material uses T8 tool steel, heat treatment hardness HRC60-65.
The beneficial effects of the utility model：
The utility model is respectively equipped with jaw mounting groove, jaw peace on the opposite clamping face of left clamp body, right clamp body
Jaw is provided with tankage, is easily changed jaw, convenient disassembly；The working surface of jaw clamping simultaneously is provided with crosswise serration, clamps
Mouth uses T8 tool steel materials, and hardness connects up to HRC60-65, the hardness with most of hardened steel silk table surface hardness after heat treatment
Closely, steel wire can be clamped, steel wire will not be caused to damage again, can preferably clamping steel wire sample, experiment is greatly improved
Stability and dependability, service life length, and two faces of jaw are provided with crosswise serration, and positive and negative can use, greatly
The big usage time for extending jaw, further extends service life；Jaw is respectively equipped with a side end face of left and right clamp body
Fixing screws, jaw is pressed in jaw mounting groove, effectively prevents coming off for jaw.Jaw mode is changed due to using, because
This, hardly with changing, reduce further manufacturing cost to clamp body.
Brief description of the drawings
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is schematic front view of the present utility model.
Fig. 3 is the schematic diagram of left clamp body, jaw and housing screw in the utility model.
In figure：The left clamp bodies of 1-, the right clamp bodies of 2-, 3- housing screws, 4- jaws, 5- jaw fixing screw holes, 6- jaws
Mounting groove.
Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, referring to the drawings to this practicality
New further description.
Referring to Fig. 1 to Fig. 3, a kind of replaceable jaw of minor diameter steel wire tension test, including symmetrically arranged left clamp body
1st, right clamp body 2, jaw mounting groove 6, jaw mounting groove 6 are respectively equipped with the opposite clamping face of left clamp body 1, right clamp body 2
In be bumped into jaw 4, the clamping working surface of jaw 4 is provided with crosswise serration；In order to extend the service life of jaw 4, on jaw 4
The another side relative with clamping working surface is also equipped with crosswise serration, and positive and negative can use.Left clamp body 1, right fixture
One side end face of body 2 is respectively equipped with jaw fixing screw hole 5, and jaw fixing screw hole 5 is connected with jaw mounting groove 6, is clamping
Being screwed into housing screw 3 in mouth fixing screw hole 5 can be pressed in jaw 4 in jaw mounting groove 6, to prevent coming off for jaw.Pincers
The groove set on mouth 4 is in 90 ° of cross arrangements, naturally it is also possible to according to the mat surface for needing to be fabricated to other forms of sample；
Jaw material uses T8 tool steel, hardness HRC60-65 after heat treatment, approaches, can press from both sides with most of hardened steel silk table surface hardness
Handle steel wire, steel wire will not be caused to damage again, can preferably clamping steel wire sample, be greatly improved the stability of experiment with can
By property, service life length.
Above-mentioned embodiment is only specific case of the present utility model, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent implementations of change.But it is every without departing from the utility model technical principle on the premise of, according to of the present utility model
Any simple modification, equivalent variations and the remodeling that technical spirit is made to embodiment of above, should all fall into of the present utility model
Scope of patent protection.
