Abstract
The utility model relates to a metal wire torsion testing machine fixture. The metal wire torsion testing machine fixture comprises a fixed jaw and a sliding jaw, and is characterized in that the fixed jaw is a cylinder with an external thread; a semi-cylindrical boss is arranged at the front end of the fixed jaw; an arc-shaped groove is formed in the plane part of the boss; a rectangular slide groove is formed in the middle of the threaded rod body of the fixed jaw behind the boss; the sliding jaw consists of a manual wheel disc and a rectangular clamping block; an internal thread is formed in the center hole of the manual wheel disc; the sliding jaw is in threaded connection with the fixed jaw; a round slideway is arranged in the manual wheel disc; the rectangular clamping block is mounted in the round slideway of the manual wheel disc and can move back and forth in the rectangular slide groove of the threaded rod body of the fixed jaw. The metal wire torsion testing machine fixture provided by the utility model has the advantages as follows: the clamping is convenient and firm, the fixture can be easily taken down and replaced, the service life is long, the requirement on the hardness of the jaws is low, and the reliability and effectiveness of a torsion test can be improved.
Description
Technical field
The utility model relates to a kind of mechanical clamp, especially a kind of metal wire torsion tester fixture, and this fixture is metal wire torsion tester moral critical component.
Background technology
Critical examination project during the twisting test of metal wire rod in Wire Rope Production is to measure the important detection means that metal wire rod bears plastic deformation ability and shows wire surface and inherent vice in torsion.
Torsion testing machine is the key equipment of twisting test, and the fixture that existing metal wire torsion tester adopts is to be mainly provided with the fixture block of upper and lower corresponding in chuck cavity, by a pair of top folder bolt rotary squeezing, the clamping work of enforcement to wire sample, such method of clamping, effort and easy damaged wire rod, firmly excessive, wire rod can be squeezed to flat, pinch off, cause invalidate the test or retry; Firmly too small, clamping is not tight, and slip gets loose, and causes test normally not carry out.And in Wire Rope Production, the skin hardness of high-carbon wire rope processed and the hardness of Chuck jaw approach, cause Chuck jaw not long serviceable life, change frequent.
Summary of the invention
The deficiency that the utility model exists for prior art, provides a kind of clamping firmly convenient, and unloading clip is changed easily, and long service life and not high to jaw hardness requirement can effectively improve the metal wire torsion tester fixture of twisting test reliability and validity.
The utility model is achieved through the following technical solutions: a kind of metal wire torsion tester fixture, comprise regular jaw and sliding jaw, described regular jaw is with externally threaded right cylinder, its front end is provided with half-cylindrical boss, boss planar section arranges deep-slotted chip breaker, offers rectangle chute in the middle of the jaw screw thread shaft of boss rear portion; Described sliding jaw is comprised of manual wheel disc and rectangle fixture block, and manual pulley center hole is provided with internal thread, is threaded connection with regular jaw, manually in wheel disc, circular slideway is set; Described rectangle fixture block is arranged in the circular slideway of manual wheel disc, can in the rectangle chute of regular jaw screw thread shaft, move forward and backward.
The profile diameter of described half-cylindrical boss is consistent with the cylindrical shape diameter of regular jaw;
The arc two ends width of described deep-slotted chip breaker is consistent with the rectangle chute groove width of regular jaw screw thread shaft;
Described circular slideway peripheral hardware has slideway notch;
The beneficial effects of the utility model are: owing to having offered rectangle chute on its regular jaw, and be threaded connection with sliding jaw, and the rectangle fixture block of sliding jaw can move forward and backward in rectangle chute, like this by the manual wheel disc of pivoted jaw, drive rectangle fixture block to move to the half-cylindrical boss place of regular jaw, thereby clamping needs the wire sample of test, clamping is firmly convenient, be convenient to fixture block handling, long service life, adapt to the metal wire rod clamping of different size, hardness, can effectively improve reliability and the validity of twisting test.
The utlity model has clamping convenient firmly, unloading clip is changed easily, and long service life and not high to jaw hardness requirement can effectively improve the advantage of twisting test reliability and validity.

Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
The utility model specific embodiment is: a kind of metal wire torsion tester fixture, comprises regular jaw 1 and sliding jaw 2.
Described regular jaw 1 is with externally threaded right cylinder, its front end is provided with half-cylindrical boss 11, the half-cylindrical profile diameter of boss 11 and the cylindrical shape diameter of regular jaw 1 are consistent, in the middle of half-cylindrical boss 11 rear portion jaw screw thread shafts, offer rectangle chute 12; Half-cylindrical boss 11 planar sections arrange deep-slotted chip breaker 13, and the arc two ends width of deep-slotted chip breaker 13 is consistent with rectangle chute 12 groove widths of regular jaw 1 screw thread shaft,
Described sliding jaw 2 is comprised of manual wheel disc 21 and rectangle fixture block 22, and manually wheel disc 21 center pits are provided with internal thread, is threaded connection with regular jaw 1, and manually wheel disc 21 is interior arranges circular slideway 23; Described rectangle fixture block 22 is arranged in the circular slideway 23 of manual wheel disc 21, can in the rectangle chute 12 of regular jaw 1 screw thread shaft, move forward and backward; Described circular slideway 23 is outer is provided with slide groove mouth 24, is convenient to the handling of rectangle fixture block 22.
The utility model clamping course of work is described further: sliding jaw 2 is arranged on regular jaw 1, it comprises manual wheel disc 21 and rectangle fixture block 22, rotation manual wheel disc 21, by with being threaded of regular jaw 1, drive rectangle fixture block 22 along F direction, to move to half-cylindrical boss 11 places of regular jaw 1, thereby wire sample 3 clampings are compressed, realize the fixedly object of wire sample 3.Start after torsion testing machine, moment is delivered to the bare terminal end of wire sample 3 by regular jaw 1, and now the bare terminal end of wire sample 3 plays dead man effect, drives wire sample 3 to circle around axis, thereby realizes the object of wire sample 3 twisting tests.
