Abstract
The utility model belongs to inspection detection field, and in particular to a kind of round-link chain fixture for universal testing machine.It is made up of a neck and two jig arm, the neck is used to fix with the jaws of universal testing machine, and the opening between described two jig arm is used to place round-link chain, and there is perforate the side of described two jig arm, and the perforate is used to insert pin clamping rings chain.There is groove the side of described neck, and groove position can adjust according to the jaw of universal testing machine, with the frictional force between increase and universal testing machine jaws.The utility model is simple and practical, easy to operate, and the front jig grip force solved is less than normal, caducous problem.
Description
Technical field
The utility model belongs to inspection detection field, and in particular to a kind of annulus chain folder for universal testing machine
Tool.
Background technology
Universal testing machine is to control digital wideband electrohydraulic servo valve using microcomputer, drives precision liquid cylinder pressure, microcomputer
Control system carries out various modes to test force, displacement, deformation and automatically controlled, complete stretching to metal material and component,
Compression, beam test, meet standard GB/T/T228-2010《Metal material tensile testing at ambient temperature》Requirement and other
Standard requirement.
The high-tensile round-link chain in the fields such as mine, metallurgy, ship, credit rating is higher, when the performance for carrying out A, B level product
During experiment, because toroidal is irregular, the fixture of universal testing machine can not meet the requirement of tension test, and round-link chain easily takes off
Fall, it has not been convenient to carry out mechanical property test.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of round-link chain fixture for universal testing machine.
In order to solve the above problems, the utility model uses following proposal：
A kind of round-link chain fixture for universal testing machine, it is made up of a neck and two jig arm, the neck
To be fixed for the jaws with universal testing machine, the open slot between described two jig arm is used to place round-link chain, and described two
There is perforate the side of individual jig arm, and the perforate is used to insert pin clamping rings chain.
As a preferred embodiment, there is groove the side of described neck, groove position can be according to the pincers of universal testing machine
Mouth adjustment, with increase and the frictional force between universal testing machine jaws.
In the groove, the width of each groove is 8mm, and angle is 60 °.
Pin simple shape, it is easy to process, the appropriate thickness that subtracts can be carried out according to high-tensile round-link chain actual size and is thinned i.e.
Can.
Band certain radian, avoids stress concentration, can extend service life at the angle of the utility model end.
Fixture of the present utility model is applied to the high-tensile round-link chain of φ 12mm~φ 18mm scopes.
The fixture grip force of currently used universal testing machine is less than normal, easy during the irregular workpiece tension test such as round-link chain
Come off, effect is bad.Fixture of the present utility model, it is simple and practical, it is easy to operate, preferably resolve the mechanics of round-link chain
Property test problem.
Brief description of the drawings
Fig. 1, the front view for the round-link chain fixture of universal testing machine.
Fig. 2, the side view for the round-link chain fixture of universal testing machine.
In figure, 1- necks, 2- jig arm, 3- perforates, 4- grooves.
Embodiment
As shown in figure 1, a kind of round-link chain fixture for universal testing machine, by a neck 1 and two 2 groups of jig arm
Into the neck 1 is used to fix with the jaws of universal testing machine, and the open slot between described two jig arm 2 is used to place
There is perforate 3 round-link chain, the side of described two jig arm, and the perforate is used to insert pin clamping rings chain.
As a preferred embodiment, there is groove 4 side of described neck 1, groove position can be according to universal testing machine
Jaw adjusts, with the frictional force between increase and universal testing machine jaws.
During using the fixture, two fixtures are taken, it is each up and down to lay one, the neck of clamp strap groove is placed on respectively omnipotent
Step up at the jaw of Material Testing Machine, pin is extracted out, round-link chain one end is put into upper clamp opening, insertion pin passes through circle
Loop chain, so as to clamping rings chain.Round-link chain other end sampling same method is connected in lower clamp, opens universal testing machine,
It can be tested by testing regulations, as long as when the round-link chain that round-link chain fracture more renews extracts pin by the round-link chain of fracture
Take out, new experiment can be carried out by changing new round-link chain and plugging pin, and the jaw of testing machine need not adjust, very convenient, effect
Rate is very high, and effect is fine.
