Description
Affiliated technical field
The utility model relates to a kind of band stretching mechanical property testing anchor clamps, and the clamping device that test has certain rigidity and flexible strip material extending mechanical property belongs to stripping mechanics performance testing technology field.
Background technology
In the engineering, the material that has has certain rigidity, also certain flexibility is arranged, as plastics GSZ, steel mould compound geogrid, steel is moulded composite reinforced band etc.; What its Mechanics Performance Testing was commonly used is terrace with edge shape or rectangle jaw anchor clamps, and comes the clamping sample through tightening connecting screw rod, still; When reality was used, overtorquing can cause sample damage at the jaw place, twists the sample that can cause again too loose and in anchor clamps, skids; Be difficult to the control clamping force, bring certain error to test result.To steel and plastic composite material, existing anchor clamps can more accurately be tested Mechanical Properties of Steel Wire, and the someone proposes through testing its Mechanical Properties of Steel Wire; Converse the mechanical property of band; And the tensile mechanical properties of the plastic material of wrapping up in is outward ignored, still, and in actual engineering; Its loading characteristic is that the band coordination is stressed, and the result and the actual conditions that obtain like this are variant.
Summary of the invention
The purpose of the utility model provides a kind of band stretching mechanical property testing anchor clamps, utilizes water droplet shape self-tightening parts, reduces the jaw damage of sample, avoids sample in anchor clamps, to skid, and solves the problem of band sample in jaw place easy glide or damage.
The technical scheme of the utility model is: band stretching mechanical property testing anchor clamps; Comprise the main element 2 and water droplet shape self-tightening parts 3 that have the open holding tank of water droplet shape; Water droplet shape self-tightening parts 3 place the open holding tank of the water droplet shape on the main element 2; Form sample clamping claw 4 between main element 2 and water droplet shape self-tightening parts 3 bottoms, sample forms the self-tightening face in clamping claw 4.
Be processed with serrated slot on the surface of the sample clamping claw 4 that forms between said water droplet shape self-tightening parts 3 and main element 2 bottoms, be used for further strengthening clamping effect.
Said main element 2 is the cuboid structure, and its upper end is fixed with and is used for the connecting rod 1 that is connected with the testing machine chuck.
Rectangle baffle plate 6 is equipped with in said main element 2 outsides, can be fixing at four jiaos of places through screw, and in order to block water droplet shape self-tightening parts 3.
Said main element 2 downsides are equipped with the auxiliary clamping device of being made up of inside and outside clamping plate and housing screw 5, and inner splint can be fixed on the side of main element 2 bottoms through usual manners such as screw or welding.
These anchor clamps are with the open holding tank of water droplet shape on the main element and the water droplet shape self-tightening parts core texture as anchor clamps; Form the sample clamping claw; Utilize the self-tightening effect of water droplet shape self-tightening parts, step up effect with the serrated slot on the jaw in addition, thereby can firmly clamp the band sample.Auxiliary clamping device of setting up on the main element and rectangle baffle plate can further strengthen the degree of reliability that the band sample is clamped.Connecting rod through the main element upper end can be clamped in these anchor clamps on the testing machine chuck easily, carries out the detection test of sample.
During test, sample is put into the holding tank between main element and the water droplet shape parts, and tighten the rectangle baffle plate 6 of both sides, also in like manner clamping is good for the sample other end, then connecting rod is clamped on the chuck of testing machine.At this moment, the two ends of sample are clamped by auxiliary clamping device 5, along with the increase of pulling force, main component 2 and water droplet shape self-tightening parts 3 will be fully near, finally form self-tightening, well pincers are tight at sample clamping claw 4 places, avoided the sample slippage.Characteristic according to sample; Can sample be passed auxiliary clamping device 5 steps up once more; Sample leans on the face extruding of opposed flattened to clamp in water droplet shape holding tank like this, can reduce the jaw damage of sample preferably, has overcome in the past terrace with edge shape or rectangle jaw and has clamped the damage that causes sample.
Compare with the existing anchor clamps that use, the utility model volume is little, in light weight, and simple in structure, and convenient mounting and clamping can the load self-tightening, has overcome the stressed phenomenon of skidding of sample.Be applicable to that plastics GSZ, steel mould compound geogrid, steel and mould composite reinforced band and can have higher application and popularization value around the Mechanics Performance Testing of the compound substance of bent clamping.
