Description
Technical field
The utility model relates to a kind of clamping device of plastic tensile performance test machine.
Background technology
Plastic tensile performance test machine is used to test the tensile property of plastics, is drawing high when test, and the plastics batten is clamped in up and down in two material folding heads, goes up the material folding head then and rises and realize stretching.The clamping device of existing plastic tensile performance test machine is not easy to change, and carries out also operating when material folding is operated also cumbersome.
Summary of the invention
For the above-mentioned deficiency of the clamping device that overcomes existing plastic tensile performance test machine, the clamping device of the plastic tensile performance test machine that the utility model provides a kind of to be convenient to change, material folding is easy and simple to handle.
The technical scheme that the utility model solves its technical matters is: a kind of clamping device of plastic tensile performance test machine, comprise a joint pin, and the top of described joint pin is provided with jack, and the lower surface of said joint pin has the helicla flute that concaves;
Also comprise a lifting screw, the top of said lifting screw is stretched in the described helicla flute and is threaded with it;
Also comprise a fixing clamshell, described fixedly clamshell has the inside chuck container cavity of an opening, and described chuck container cavity has from top to bottom intilted first inclined-plane and second inclined-plane, and described first inclined-plane is relative with second inclined-plane;
First chuck, second chuck relative with described first chuck are arranged in the described chuck container cavity; The lateral surface of said first chuck and described first inclined-plane are suitable; The lateral surface of said second chuck and described second inclined-plane are suitable, are formed for the interlayer of material folding between described first chuck and second chuck;
The bottom of said lifting screw is stretched in the described chuck container cavity, and the afterbody of this lifting screw is provided with the hanging groove of a circle indent, and all there is the extension arm upper end of the upper end of said first chuck and second chuck, and described extension arm inserts in the described hanging groove.
Further, said joint pin is provided with external thread, goes back spiral shell on this joint pin and is provided with set nut.
Further, go back spiral shell on the described lifting screw and be provided with operating grip.
The utility model has an insertion chamber on the lifting table of the plastic tensile performance test machine supporting with it in use, and the top of joint pin is inserted and should be inserted in the chamber, in jack, inserts the clamping device that latch is located the utility model.When carrying out material folding, rotate lifting screw; Lifting screw is risen; Then spur first chuck and second chuck and rise because first chuck and second chuck are suitable with first inclined-plane and second inclined-plane respectively, when first chuck and second chuck rise first chuck and second chuck each other away from; Then between the two interlayer enlarges, and can the plastics batten be sandwiched in wherein.The backward rotation lifting screw descends first chuck and second chuck afterwards, thereby while first chuck and second chuck are each other near clamping the plastics batten.
The beneficial effect of the utility model is: joint pin inserts back insertion bearing pin and fixes, and therefore ten minutes is convenient to dismounting and is changed; The material folding operation is very easy.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
