Abstract
The utility model relates to a clamping device for testing the mechanical property of a steel-plastic composite geogrid, in particular to a fixture capable of carrying out a stretching test on a grid band. The structure of the device is as follows: a clamping groove is arranged on a fixture base body, a single surface of the clamping groove is open, a curved rotating block is arranged in the clamping groove by a rotating shaft, a clamping piece is arranged at the outer side of the curved rotating block, a test sample which is wound on the curved rotating block is clamped between the curved rotating block and the self-locking surface of the clamping groove, and the end part of the test sample is connected on the clamping piece. By reasonably utilizing the characteristics of loading and self-locking of the test sample, the fixture solves the difficult problems of difficult clamping, easy slipping, non-ideal breaking state and inaccurate testing results. The fixture has the characteristics of simple structure, convenient operation and high efficiency.
Description
One, affiliated technical field
The utility model relates to a kind of tested steel and moulds compound geogrid mechanical property clamping device, especially can carry out the anchor clamps of grid band tension test.
Two, background technology
It is that steel wire is rolled into high strength tapes by high density polyethylene that steel is moulded compound geogrid, at present, test its mechanical property commonly used be terrace with edge shape or rectangle jaw anchor clamps, and come the clamping sample by tightening connecting screw rod, still, when reality is used, overtorquing can cause sample to damage at the jaw place, twist the sample that to cause again too loose and in anchor clamps, skid, be difficult to the control clamping force, bring certain personal error to test result.For this reason, the someone proposes the mechanical property by the test individual wire again, converses the mechanical property of band, this anchor clamps can more accurately be tested Mechanical Properties of Steel Wire, still, and in actual engineering, the stressed of grid is that the band coordination is stressed, and the result and the actual conditions that obtain like this are variant.
Three, summary of the invention
3.1 the technical matters that solves
Sample is at damage of jaw place or easy glide when moulding compound geogrid band mechanical property in order to overcome existing tested steel, be difficult to the deficiency of clamping, the purpose of this utility model provides a kind of anchor clamps, these anchor clamps can not only reduce the jaw damage of sample, avoid sample in anchor clamps, to skid, and the clamping sample also can be regulated clamping force well voluntarily easily.
3.2 the technical scheme that is adopted
The technical scheme that its technical matters that solves the utility model adopts is: have the open holding tank of a single face on clip base, curved switch block is loaded in the holding tank by rotating shaft, clamping element is equipped with in the curved switch block outside, sample on curved switch block and be clamped on curved switch block and holding tank between locking face, the sample end is connected on the clamping element.
Described clip base profile is a rectangle, and an end face is fixed with the clamping bar that is connected with the testing machine chuck.Clamping element on the described curved switch block connects by connecting pin, and what clamping element adopted is adjusting screw(rod), and the adjusting screw(rod) end is fixed with intermediate plate.
Principle of work: during test, the sample end is put between the intermediate plate and curved switch block of clamping element, is tightened adjusting screw(rod), make intermediate plate on it and curved switch block near and clamp sample.Sample is walked around curved switch block, and the sample other end also adopts same way as to be clamped in another anchor clamps.Then the clamping bar is clamped on the chuck of testing machine.At this moment, the two ends of sample are fixed by clamping element, after sample is stressed, curved switch block will rotate around the shaft, along with the increase of pulling force, clip base can be fully close from locking face and curved switch block, finally forming self-locking, thereby avoiding the sample slippage from the locking face place.And, can reduce the jaw damage of sample preferably being that two faces extruding by opposed flattened clamps samples from the locking face place, overcome in the past terrace with edge shape or rectangle jaw and clamped the damage that causes sample.
3.3 beneficial effect
Tensile test fixture of the present utility model is compared with the existing anchor clamps that use, and volume is little in light weight, and simple in structure, convenient mounting and clamping (need not any machine tool, the free-hand clamping that just can finish sample), can the load self-locking, overcome the stressed phenomenon of skidding of sample.Mould compound geogrid and can have higher application and popularization value applicable to steel around the Mechanics Performance Testing of the compound substance of bent clamping.
