An at least guide rod, slidingtype are set on the stent, and the guide rod is slided along the support level and vertical direction It is dynamic;
Pressing plate, slidingtype are set on the guide rod, and the pressing plate is equipped with vertical through-hole, the test lead of the tensiometer It is passed through from vertical through-hole.
Preferably, the bottom plate is equipped with several first screw holes, the first screw hole cooperation screw makes plastic parts water Placing flat.
Preferably, the stent is four supporting rods, four supporting rods are articulated in the both sides of the bottom plate.
Preferably, being set on four supporting rods there are two the sliding rail being arranged in parallel, described two sliding rails are led by first It covers along the supporting rod vertical sliding.
It is set on described two sliding rails preferably, the both ends of the guide rod are slided respectively by the second guide sleeve level.
Preferably, the quantity of the guide rod is two.
Preferably, the pressing plate is equipped with two horizontal through hole, two guide rod is each passed through the horizontal through hole.
Preferably, vertical through-hole is surrounded by least four second screw holes, second screw hole on the pressing plate Screw is coordinated to compress plastic parts.
Compared to the prior art, device for testing tensile force of the invention by adjusting the position of the guide rod and pressing plate, makes pressure Plate, which is moved to plastic parts, to be needed to test the screw position of pulling force, and then the test lead of tensiometer passes through test spiral shell from vertical through-hole The resistance to value of thrust of nail, therefore, the device for testing tensile force are suitable for the plastic parts of different machines, do not need to open for different machines The jig for sending out different, reduces cost.
【Description of the drawings】
Fig. 1 is painted the structure diagram of one preferred embodiment of device for testing tensile force of the present invention.
Fig. 2 is painted the structure diagram of one preferred embodiment working condition of device for testing tensile force of the present invention.
【Specific embodiment】
Refering to Figure 1, it depicts the structure diagram of one preferred embodiment of device for testing tensile force of the present invention.
In a preferred embodiment, device for testing tensile force of the invention, it is resistance to that cooperation tensiometer tests screw in plastic parts The pulling force received, the device for testing tensile force include:
Bottom plate 100 places the plastic parts 10 of 20 pulling force of screw to be tested on the bottom plate 100, in this present embodiment, described Bottom plate 100 is equipped with several first screw holes 110, if the plastic parts 10 of different machines cannot be horizontal positioned on bottom plate 100, First screw hole 110 coordinates screw to make plastic parts 10 horizontal positioned, has broken away from demand of the plastic parts 10 to bed die;
Stent 200 is articulated in the both sides of the bottom plate 100 vertically, and in this present embodiment, the stent 200 is four Supporting rod 210, four supporting rods 210 are articulated in the both sides of the bottom plate 100, and four supporting rods 210 are equipped with two A sliding rail 220 being arranged in parallel, described two sliding rails 220 are by the first guide sleeve 221 along 210 vertical sliding of supporting rod;
An at least guide rod 300, slidingtype are set on the stent 200, and the guide rod 300 is horizontal along the stent 200 And vertical direction slides, in this present embodiment, the both ends of the guide rod 300 are set on respectively by horizontal slide of the second guide sleeve 310 On described two sliding rails 220, simultaneously as sliding rail 220 is along 210 vertical sliding of supporting rod, and make two guide rods 300 can Vertically to slide, the quantity of the guide rod 300 is two;
