Technical field
The utility model relates to detection device technology fields, more particularly to a kind of universal testing machine.
Background technique
Universal testing machine is a kind of equipment that the mechanical property for a variety of materials is tested.By stretching, compressing
The basic mechanical performance index of material can be obtained in equal tests, such as bends and stretches intensity, tensile strength, elongation, elasticity modulus.
The universal testing machine of the prior art, mainly by pedestal, upper beam, lower beam, two support columns, two screw rods and driving system
System composition.The top of pedestal is equipped with workbench, and drive system is mounted in pedestal.Two support columns or so distribution, two support columns hang down
It directly is installed on the workbench and is fixed with workbench, two support columns are vertically arranged and left and right is distributed, one end energy of two screw rods
It is enough rotatably mounted at upper beam, the other end of two screw rods is connect with drive system, same to realize under the driving of drive system
Step rotation.Lower beam is covered on two screw rods and is connect with two wire rod threads.
The working principle of universal testing machine is to drive two screw rods to rotate synchronously by drive system, since screw rod is under
Crossbeam is threadedly coupled, and screw rod will drive lower beam and move up and down when rotating, be fixed between lower beam and workbench wait measure and monitor the growth of standing timber
Material, in lower beam under the action of moving up and down, measurement to be measured is stretched or compressed, and then obtains detected materials by sensor
Relevant basic mechanical performance index.
However, the length due to screw rod is usually longer, screw rod is easy to happen round jump in the rotation, and screw rod occurs circle and jumps
Afterwards, screw rod will drive lower beam to swing, and lower beam swing can cause detected materials to generate additional deformation, lead to test data not
Accurately.
Utility model content
Based on this, it is necessary to provide a kind of universal testing machine that circle jump can occur to avoid screw rod, make universal testing machine
Test result is accurate.
A kind of universal testing machine, including pedestal, upper beam, lower beam, at least two support columns, two screw rods and drive system,

As shown in Figs. 1-2, the utility model embodiment provides a kind of universal testing machine, including pedestal 1, upper beam 3, lower cross
Beam 4, at least two support columns 5, two screw rods 6 and drive system 7.The top of pedestal 1 is equipped with workbench 2, and drive system 7 is mounted on bottom
In seat 1, support column 5 is vertically mounted on workbench 2 and fixes with workbench 2, and upper beam 3 is fixed on the top of support column 5.Two
Screw rod 6 is vertically arranged and one end of two screw rods 6 is rotatably mounted on upper beam 3, and the other end of two screw rods 6 wears work
Platform 2 is simultaneously connect with drive system 7, and is rotated synchronously under the driving of drive system 7.Lower beam 4 and two screw rods 6 socket and with silk
Bar 6 is threadedly coupled, and lower beam 4 can be slidably socketed at least two support columns 5.
It is appreciated that screw rod 6 when there is the trend of circle jump, can be such that lower beam 4 puts the application of lower beam 4 in rotation
Dynamic power, lower beam 4 are swung, and round jump can just occur for screw rod 6, and since lower beam 4 and support column 5 are socketed, screw rod 6 is to lower beam
4 active force can be married again to support column 5, and support column 5 is fixed, so support column 5 will not be swung, 5 dead beat of support column
Dynamic, lower beam 4 can not equally be swung, i.e., lower beam 4 can provide active force to screw rod 6, made screw rod 6 that round jump can not occur, protected
Card lower beam 4 is merely able to move up and down, be fixed on detected materials between lower beam 4 and workbench 2 will not the outer deformation of amount incurred,
To keep the test result of universal testing machine accurate.
In the present embodiment, lower beam 4 is connect by linear bearing 8 with support column 5, and setting linear bearing 8 can make to prop up
It is really up to the mark between dagger 5 and lower beam 4 to be coupled, and in really up to the mark be coupled, guarantee that lower beam 4 can be along support column 5
It slides up and down.The structure and the prior art of linear bearing 8, details are not described herein.It is appreciated that between support column 5 and lower beam 4
Really up to the mark be coupled can guarantee that small sway will not occur for lower beam 4.
In the present embodiment, linear bearing 8 is embedded in lower beam 4 and affixed with the lower beam 4.
In this example, support column 5 is polished rod, to reduce the frictional force between lower beam 4 and support column 5, convenient lower cross
Beam 4 slides.
In the present embodiment, the quantity of support column 5 is four, and in pairs, two groups of support columns 5 are set to four support columns 5
Two opposite ends of workbench 2, the i.e. structure can guarantee that the circle of screw rod 6 is jumped power and acted on more support columns 5, support column quantity
More, single support column stress is smaller, and support column is less susceptible to swing.
In the present embodiment, lower beam 4 be equipped with screw rod external member 9, screw rod 6 wear screw rod external member 9 and with 9 spiral shell of screw rod external member
Line connection, realization are threadedly coupled with lower beam 4.Specifically, screw rod external member 9 wears lower beam 4 and affixed with lower beam 4, in this way
When screw rod 6 wears screw rod external member 9, lower beam 4 is socketed on lead screw 6 simultaneously.Screw rod external member 9 is, for example, long nut or has interior
The sleeve of screw thread, lower beam 4 are equipped with the perforation that screw mandrel external member 9 is worn, and screw rod external member 9, which is worn, perforates and for example pass through welding
Mode and lower beam 4 it is affixed, the principle that screw rod external member 9 and screw rod 6 cooperate is the prior art, and details are not described herein.At other
In embodiment, screw hole is set on lower beam 4, for example to be threadedly coupled with screw rod 6.
