Description
Technical field
The present invention relates to clamp system, and in particular to the application method of adjustable test for tensile strength templin chuck.
Background technology
Universal testing machine, integrate the Material Testing Machine of the functions such as stretching, bending, compression, shearing, ring stiffness, mainly
It is industrial and mining enterprises, R＆D institution, universities and colleges, engineering quality supervision station etc. for metal, nonmetallic materials mechanical property test
The preferable detection device of department.Universal testing machine is also universal testing machine, or puller system, double lead series, control, surveys
Amount, operation integral structure, melt contemporary advanced in one, there is precision height, speed-regulating range width, compact-sized, operation side
Just, steady performance.Suitable for the drawing of the material samples such as plastics, waterproof material, textile, paper products and rubber and product
Stretch, compress, bending, creep test and can directly to carry out the flat compression (compression recovery) of tubing, ring stiffness equipped with big platen (anti-outer
Load), creep ratio, the experiment such as ring tensile strength.
Universal testing machine is the product that modern electronic technology is combined with mechanical transmissioning technology, be given full play to it is electromechanical each
The large-scale precision tester formed from speciality, various materials can be stretched, compress, bend, peeling off, shearing etc. and be multinomial
Performance test, and have the features such as measurement range is wide, precision is high, response is fast.Reliable operation, efficiency high, test data can be carried out
Real-time display record, printing.Universal testing machine is by measuring system, drive system, control system and computer (computer system
Type tensile testing machine) etc. structure composition.If existing universal testing machine on the market can be divided into measure machinery according to purpose classification
The testing machine and engineer testing testing machine of performance, universal testing machine engineer testing testing machine, can carry out force measurement, i.e.,
Measurement is realized by force cell, amplifier and data handling system, the most frequently used force cell is that strain chip passes
Sensor.
Tensile strength be characterize material maximum uniform plastic deformation drag, tensile sample bear maximum tension stress it
Before, deformation is uniformity, but after exceeding, metal starts necking occur, that is, produces and concentrate deformation；For not having
The fragile material of (or very little) uniform plastic deformation, it reflects the fracture resistance of material.Tensile test, for studying measure gold
Belong to the important method of mechanical property, electron type automation tensile testing machine obtains widely used.Tensile test, generally refer to stretch
Experiment, tension test can determine a series of intensity indexs and plasticity index of material.Intensity typically refers to material and used in outer masterpiece
Lower resistance produces elastic deformation, plastic deformation and the ability of fracture.Plasticity refers to that metal material produces plasticity under load effect
The ability that deforms and will not destroy, conventional plasticity index is elongation percentage and the contraction percentage of area.
Existing universal testing machine, the chuck applied are generally templin chuck, templin chuck during tensile test specimen,
Always clamped and relaxed along a wedged gap, if wedged gap takes higher value, bayonet socket amount of expansion is big, test specimen
Easily it is loaded and dismantles, but poor in self, test specimen is clamped, bayonet socket tooth should then pay larger cutting force, such bayonet socket
The phenomenon for occurring skidding or collapsing tooth, and bayonet socket decline are easy for, if wedged gap takes smaller value, although bayonet socket amount of expansion
It is small, but chuck self-locking performance is strong, and test specimen is easily clamped lock jail, particularly easily non-ferrous metal test specimen and soft test specimen clamped
Lock jail, however, hold it is tighter, lock more firm, test specimen residuum dismounting it is more difficult.In consideration of it, some testing machines use hydraulic wedge
Clevis head, this could not only tackle the problem at its root, and occur the hydraulic jack easily new contradiction of leakage or permeability often on the contrary, make
Experiment is affected.

In above-mentioned steps, the joint of wedge-shaped clamping plate 2 and wedge-shaped bayonet socket 3 is provided with pressing plate 6, and pressing plate 6 is solid by screw 5
It is scheduled on wedge-shaped clamping plate 2, avoids wedge-shaped bayonet socket 3 from being slid from the inner fovea part of wedge-shaped clamping plate 2.Wedge-shaped bayonet socket 3 is plane wedge, i.e. wedge
The composition surface of clevis plate 2 and wedge-shaped bayonet socket 3 is the inclined-plane of plane wedge, and mounting groove 9 is rectangle locating slot, the peace of wedge-shaped clamping plate 2
The axis of tankage 9, the through hole of wedge-shaped bayonet socket 3 and guide rod 7 is consistent with the bevel direction of plane wedge, to ensure wedge-shaped bayonet socket 3
Moved up and down along wedged gap α, wedge grip angle beta >=40 ° of wedge-shaped clamping plate 2, wedged gap α≤30 ° of wedge-shaped bayonet socket 3.
Embodiment two
The present embodiment and the difference of embodiment one are that wedge-shaped bayonet socket 3 is arc surface wedge, and mounting groove 9 is fixed for annular
Position groove, the mounting groove 9 of wedge-shaped clamping plate 2, the through hole of wedge-shaped bayonet socket 3 and the axis of guide rod 7 and the arc generatrix side of arc surface wedge
To consistent, to ensure that wedge-shaped bayonet socket 3 moves up and down along wedged gap α.
Embodiment above, the purpose of the present invention, technical scheme and beneficial effect are carried out further in detail
Illustrate, should be understood that the embodiment that these are only the present invention, the protection model being not intended to limit the present invention
Enclose, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., should be included in the present invention
Protection domain within.
