Description
Technical field
The utility model relates to a kind of proving installation of parts, particularly a kind of test unit of the pulling strengrth for test piece.
Background technology
A kind of large diameter bolt tension tester is disclosed in the Chinese patent database, its notification number is: CN102235940A, open day is 2011-11-09, and this device is two header boards about the base of level arranges, four support cylinder support and connection of rectangular arrangement between header board; In the plate face center of two header boards, slide in opposition stretches into stretching pull bar and test pull bar respectively, and stretching pull bar and test pull bar termination dispose one pair of bolt tension separately and attach; The test pull bar is positioned at the inboard of header board, and the punching cushion cylinder is fixed on the test pull bar with thread forms, and the test pull bar passes header board and punching pressure transducer laterally in succession, by adjusting sleeve with the thread forms rotational lock; The stretching pull bar passes the axis hole of the punching oil cylinder of header board and band buffering laterally, and its end is locked with spiral form by set nut, and computing machine is controlled and record punching oil cylinder and punching pressure transducer.This device can carry out extension test to large diameter screw rod and corresponding shaft-like workpiece, but also there is following weak point in it:
One adopts support cylinder to support two header boards, and the length that makes it to test is shorter, and support cylinder is unfit to do longly, more long more easy deflection deformation, and therefore, this device is not suitable for the long pull bar of testing length, for example 30 meters long reinforcing pull rods.
They are two years old, for thick, long workpiece, general weight is bigger, usually need to be transported to test position by other means of transports such as fork truck, because pull bar is between support cylinder, fork truck can not directly transport workpiece and put in place, after needs adopt other instruments liftings to put in place, just can test, influence the efficient of test.
Its three because the spacing between the support cylinder is fixed, exceed the outer workpiece of support cylinder interstice coverage for size, because of interference mutually, can't install and can not test.
Its four, the dismounting inconvenience of test piece, the position is relatively narrow and small.
The utility model content
The purpose of this utility model provides a kind of tension tester, can carry out tensile test to farm labourer's part, big workpiece easily, and its bearing capacity is big, the test reliability height.
The purpose of this utility model is achieved in that a kind of tension tester, comprises two girders that are arranged in parallel, and links to each other through the horizontal frame that blocks between the end top of two girders, links to each other through cylinder bracket between the other end top; The described horizontal frame center of blocking is provided with connector, and the portion of expanding of connector root conflicts in the horizontal frame outside of blocking; Oil cylinder is installed on the cylinder bracket, the hollow piston rod that arranges in the oil cylinder stretches out from the oil cylinder two ends, pull bar cooperates and to pass described piston rod, and the pull bar outboard end nut that has been threaded is set with pressure transducer on the described pull bar between the outer end of nut and piston rod; The end in opposite directions of described pull bar and connector is respectively equipped with connecting portion.
During this device work, workpiece to be tested two ends are separately fixed on the described connecting portion, drive cylinder action then, be pulled outwardly workpiece, by changing the input pressure of oil cylinder, can realize being attached to the variation of the pulling force on the workpiece, this variation passes to corresponding display device through pressure transducer.Compared with prior art, the beneficial effects of the utility model are: cylinder bracket and the horizontal frame that blocks protrude from girder top, and its space is not subjected to the restriction of girder spacing, makes the operating space big, can test farm labourer's part, the super wide workpiece of size; Adopt technique scheme, only need an oil cylinder to test workpiece, its bearing capacity is big, the test reliability height.This device can be used for testing the suspender, wire rope, suspension hook, shackle of big load etc., not only can test its tensile strength, can also do torture test to workpiece by feeding pulse oil to oil cylinder.
For the load-bearing capacity that further guarantees this device is strong, described girder two ends upside is fixedly connected with respectively shores frame, shores frame and withstands on respectively on cylinder bracket and the horizontal inner side end that blocks frame.Frame withstands cylinder bracket and the horizontal frame that blocks can increase cylinder bracket and horizontal intensity of blocking frame by shoring.
It further improves and is that the described frame of shoring is welded into lattice-shaped by plate, shores the compressive strength of frame along the length direction distribution gradient of girder, and intensity is more big more laterally.The intensity of shoring frame what size becomes corresponding relation, and is namely more big the closer to its size of girder end.
As further improvement of the utility model, be interval with some recesses on the described girder, to shore frame bottom and be provided with the projection suitable with recess, described projection snaps in the recess, shores between frame and the girder to be connected through screw rod.This scheme has guaranteed not to be subjected to shearing force on the screw rod, has guaranteed that the load-carrying properties of device are good.When the link position of screw rod is positioned at the middle part of recess, can be better with projection and recess clamping.
For realizing accessible test, described two girders are embedded under the mattess, and the upper surface of girder is concordant with ground.Means of transport can pass through at girder, can more easily workpiece be transported to test point, can also use side by side organizing this device more, and more large-scale workpiece is carried out Combined Trials.
