According to the invention, tooth threads are adopted on the clamping plates of the clamp to occlude; the pulling rod adopts a reversed technology to occlude the wire harness and the clamping plates together; the clamp plates clamp the wire harness tighter when the pulling force testing machine pulls higher; pulling force testing accuracy is improved greatly; meanwhile, the pulling rod is adopted to drive the force arms, so as to greatly relieve labor intensity of operating personnel, and improve production efficiency.
Description
Technical field
The present invention relates to automotive wire bundle field, particularly to a kind of tension test fixture.
Background technology
Tensile test is the indispensable important step of Wiring harness terminal crimping, it is no matter ground terminal or binding post if because crimping specification problem, easily cause other continuity problem, the serious consequence got loose etc. such as loose contact, short circuit etc or terminal.
The fixture used on existing tensile test device, often can not make it clamp during dress electric wire, or open during fixture the most laborious, do not clamp due to electric wire or open during fixture the most laborious, result in tensile test numerical value inaccurate, cause wire harness quality to be difficult to ensure that, affect work efficiency.
Summary of the invention
For overcoming the shortcomings and deficiencies of above-mentioned prior art, the invention provides a kind of easy to operate, fixture that practicality is higher.
Technical scheme of the present invention is:
A kind of tension test fixture, including jig main body, and
Pull bar, is arranged at the jig main body left and right sides by bolt；
The left arm of force, the right arm of force, be symmetricly set in jig main body leading flank, and be flexibly connected with jig main body by bolt；
Left clamping plate, are bolted to the protrusion on the left arm of force and on left clamping plate and are limited in the groove on pull bar；With
Right clamping plate, are bolted to the protrusion on the right arm of force and on right clamping plate and are limited in the groove on the right of pull bar.
Left clamping plate and right clamping plate use tooth stricture of vagina to be mutually twisted.
Also including the elastic component for pull bar being retracted initial point, described elastic component one is mounted on jig main body, and other end is articulated on pull bar.
Also include the fixing head using threaded engagement to be fixed on jig main body, be used for fixedly mounting whole fixture.
The invention has the beneficial effects as follows: a kind of tension test fixture that this case proposes, use the occlusion of tooth stricture of vagina on fixture clamping plate, and pull bar uses reverse engineering, makes wire harness firmly be interlocked with clamping plate, the most past pull-up of measurer for pulling force is the tightest, is greatly improved the precision of tensile test.Meanwhile, have employed the pull bar band arm of force, significantly reduce the labor intensity of operating personnel, improve production efficiency.

Detailed description of the invention
Understand the technology contents of the present invention for convenience of those skilled in the art, below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail.
It is a kind of wire harness tension test fixture as shown in Figure 1, including jig main body, pull bar, the left arm of force, the right arm of force, left clamping plate and right clamping plate.Pull bar is arranged at jig main body two ends, the described left arm of force and the right arm of force by bolt and is arranged at the front side door of jig main body by bolt, and the left arm of force, the right arm of force can each rotate around this bolt axis at a sector region.Left clamping plate are bolted to the protrusion on the left arm of force and on left clamping plate and are limited in the groove on pull bar, and right clamping plate are bolted to the protrusion on the right arm of force and on right clamping plate and are limited in the groove on the right of pull bar.
During work, manually pulling down pull bar 1 and make left clamping plate and right clamping plate open, wire harness is placed in the middle of left clamping plate and right clamping plate, hands releasing lever, spring 7, by extended state return, drives pull bar then to make left clamping plate and right clamping plate step up.Now, measurer for pulling force is pulled up test fixture carried out tensile test by fixing head 3.After tensile test completes, manually pull down pull bar and make left clamping plate and right clamping plate open, take out wire harness, be then placed in new wire harness and carry out wire harness test next time.
Wherein, the pilot process of the pull bar left clamping plate of drive and right clamping plate is: the pull bar of tension test fixture uses lever principle, manually pull down pull bar 1 by drawing pole gain 12 and left clamping plate, the cooperation of the protrusion 11 on right clamping plate drives left clamping plate, right clamping plate move up and down, simultaneously because the left arm of force, the right arm of force is installed on jig main body by bolt, the arm of force can rotate around this bolt, and the left arm of force, the other end of the right arm of force is further through being bolted to a left side, on right clamping plate, therefore, left clamping plate, right clamping plate also and then rotate in certain amplitude around left arm of force bolt 4 and right arm of force bolt 6, due to arm of force bolt 4, 6 are fixedly mounted on jig main body, so it is left, right clamping plate step up when bottom, open when the top, namely:
1) when the arm of force moves to bottom, the vertical dimension of arm of force other end (making circular motion end) distance jig main body side is maximum, and left and right clamping plate clamp；
2) when the arm of force moves to topmost, the vertical dimension of arm of force other end (making circular motion end) distance jig main body side is minimum, and left and right clamping plate open.
Tension test fixture in this programme, pull bar 1 adds back-moving spring, when pulling dynamic pull bar, pulls open fixture, re-closes owing to spring drives pull bar to make fixture reset, alleviate the labor intensity of operating personnel, add working performance after loosing one's grip.
Jig main body uses solid steel, adds service life and the tensile strength of fixture.Fixing head uses spiral fixed form, convenient dismounting and replacing fixture.
Left clamping plate and right clamping plate use the tooth stricture of vagina being mutually twisted, during tensile test, measurer for pulling force pulling force is upwards, wire harness is downward to the active force of clamping plate, makes the wire harness on fixture more draw the distance of the most left clamping plate and right clamping plate the least, and chucking power is the biggest, the tightest to harness clips of clamping plate, more it is difficult to slip get loose, makes the precision of measurer for pulling force improve, be greatly improved quality.
Above-described embodiment is only the wherein specific implementation of the present invention, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these obvious alternative forms belong to protection scope of the present invention.
