Abstract
The utility model relates to a tester which can correctly measure the anti-pulling of cable, line elongation and cable clamping holding force. A pair of tension pliers and a pair of gauge head pliers are reversed translated opened, always ensuring the axis center of cable concentric with the force shaft. The nips of the pulling force pliers and the gauge head pliers are respectively provided with a pair of guide screws for measurement of the anti-pulling strength of the cable and the core line. The front end of the nip of the gauge head pliers is an oblique blade which can hang the pipe wall port of the cable connection clamp for measuring the holding force. A guide way of the pulling force pliers and the surface of the bottom seat are provided with the graduations for displaying the line elongation. When the force handle is upwards lifted, a gear is rotated, a rack is further pulled to left translation, and the gauge head pliers are dragged for left translation by the part to be measured.
Description
(1) technical field
The utility model relates to a kind of cable stretch tester, is applicable to the test of cable tension, line length growth rate and strain relief clamp bond stress.
(2) background technology
The anchor clamps of general wire rod tension tester adopt drill chuck (three-jaw), and it is unreasonable to survey the bond stress clamp; Flat-nose pliers is regulated single jaw can not guarantee that cable axle center and mechanical axis are concentric, and measuring has error.
(3) summary of the invention
The purpose of this utility model provide a kind of can be to cable tension, line length growth rate and strain relief clamp bond stress tester of correct measurement all.Its objective is such realization:
Be fixed with gear train E at support D downside, above an end Pulling force pincer A is housed, the other end is being fixed gauge stand C and table heading pincer B.It is characterized in that: Pulling force pincer A and table heading pincer B are reverse translational opening-closing, guarantee that all the time cable axle center and mechanical axis are concentric.The jaw place of Pulling force pincer A and table heading pincer B has a pair of jackscrew A9, B8 respectively, is used for the measurement of cable core tensile strength.All there is scale the side of the guide rail A2 upper surface of Pulling force pincer A and Pulling force pincer base A1, with the display line length growth rate.Gauge outfit (draw-bar donamometer F) probe is connected with table heading pincer tailstock B11.Gauge stand C rear portion is a movable pressing board C2 with the screw locking, has both guaranteed the stability of draw-bar donamometer F, also makes things convenient for the dismounting of draw-bar donamometer F.
When upwards lifting power handle E, transmitting gear E2 advances your gear teeth and stirs tooth bar E1 to left, drags table heading pincer B by measured piece (wire rod) and moves to left thereupon.Phase one, wire rod does not stretch, and becomes staticly up to table heading pincer B by moving, and Pulling force pincer A will constantly move to left, and writes down this turnover displacement scale a constantly, shows to have entered subordinate phase-wire stretching.Continue to pull pulling force handle E, no longer extend to wire rod, table heading pincer B begins again to move, pull apart or the slippage of cable connection card up to wire rod, write down the displacement b of Pulling force pincer A and the indicated number c of draw-bar donamometer this moment again, (b-a) be the length growth rate of wire rod, c is the tensile strength of wire rod or the bond stress of cable connection card.

(5) embodiment
The jaw mesopore tapping thread of Pulling force pincer A and table heading pincer B all is: left jaw A3 (or B6) is left-handed (left-hand thread), and right jaw A4 (or B7) is dextrorotation (right-hand thread).The corresponding hitch of leading screw A5 (or B3), its left end is left-handed, and its right-hand member is dextrorotation, and Pulling force pincer A is identical with the thread size correspondence of table heading pincer B leading screw separately and screw.When leading screw A5 (or B3) is left-handed. the inevitable synchronous backward of left jaw A3 (or B6) and right jaw A4 (or B7) moves outward, and jaw is opened, on the contrary, when leading screw A5 (or B3) dextrorotation, move in the inevitable again synchronous backward of left jaw A3 (or B6) and right jaw A4 (or B7), jaw closes up.Thereby guarantee that in the process that jaw closes up the cable axle center is concentric with mechanical axis all the time.
Measure the cable of band sleeve pipe (or sheath is arranged) and measure cable core, there is perpendicular groove the jaw inboard of Pulling force pincer, its jackscrew A6 can be with can be (when wishing cable grip tighter, just with), and jaw B6, the B7 of table heading pincer B be shown in " Figure 14 ", front end is an oblique sword, can damage cable, therefore, must use jackscrew B8 clamping cables, jaw B6, B7 do not allow to close up on the contrary.When measuring cable connection card bond stress, then table heading pincer B must lean on jaw B6, B7 to tangle the tube wall port of cable connection card, and can not use jackscrew B8.
On the guide rail A2 of Pulling force pincer A He on the base A1 scale is being arranged all, the scale of the right guide rail upper surface of Pulling force pincer is the 1mm of unit, and total length is 7cm, and every 10mm place indicates the cm number; The scale of the right lateral surface of Pulling force pincer base is the 1mm of unit, and total length is 5cm, and every 5mm place indicates preface sign indicating number (0,1,2,3,4,5,6,7,8,9,1).Its function class is like vernier caliper, and measuring accuracy is 2%mm.Because tested line length is not necessarily or exceptionally straight degree difference, the initial position of Pulling force pincer A also not necessarily scale be zero place, so should write down initial value, it does not influence the result of length growth rate certainly.
Because base mesopore and jaw mesopore are all concentric with leading screw, leading screw and jaw must assemble earlier, and jaw does not close up, and is to open.And base two risers are fixed as one, and leading screw and jaw assembly can't insert., the leading screw perforation of base is cut along horizontal diameter, top becomes a pressing plate, and is fastening with screw, can be convenient for assembly for this reason.
