Abstract
The utility model discloses a kind of low frequency electo hydraulic servocontrolled fatigue testing machine unit clamp, low frequency electo hydraulic servocontrolled fatigue testing machine unit clamp, comprise chuck (1), folder cylinder (2) and chuck (3).The outside cylinder diameter 1mm less of the outside cylinder diameter of folder cylinder of this fixture chuck, can make this fixture have guidance quality like this, be convenient to install.This clamping fixture head on the surface with 90 ° for separatrix is evenly distributed with four open slots, fixture can be made like this to have elasticity, when making clamp, can by fixture steel wire clamping.This clamping fixture head and folder cylinder have through hole, and chuck does not have through hole, can limit the length that steel wire stretches into, and carries out spacing.This fixture structure is simple, easy to use and cheap for manufacturing cost.
Description
Technical field
The utility model relates to steel wire detection field, particularly a kind of low frequency electo hydraulic servocontrolled fatigue testing machine unit clamp.
Background technology
Fatigue tester is the machine of experiment on fatigue properties being a kind ofly mainly used in measuring metal and the stretching of alloy material under room temperature state thereof, compressing or draw, press stress alternation.In the axial fatigue performance test for metal material, the equipment adopted at present is electro-hydraulic servo fatigue experimental machine mostly.Fixture when usual fatigue experimental machine has Wedge gripping, horizontal sliding fixture and a cylinder.Shortcoming is that plain clamp is heavier, changes cumbersome, needs two people to operate together, both time-consuming, takes manpower again, inefficiency.
Prior art is compared, and the beneficial effects of the utility model are:
1. the outside cylinder diameter of this fixture chuck 1mm less of the outside cylinder diameter of folder cylinder, can make this fixture have guidance quality like this, be convenient to install.
2. this clamping fixture head on the surface with 90 ° for separatrix is evenly distributed with four open slots, fixture can be made like this to have elasticity, when making clamp, can by fixture steel wire clamping.
3. this clamping fixture head and folder cylinder have through hole, and chuck does not have through hole, can limit the length that steel wire stretches into, and carries out spacing.
4. this fixture structure is simple, easy to use and cheap for manufacturing cost.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of low frequency electo hydraulic servocontrolled fatigue testing machine unit clamp, this Steel Wire Surface dust arrester simple structure, easy to use and cheap for manufacturing cost.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: comprise chuck, folder cylinder and chuck; Folder cylinder is right cylinder cavity, and centre is provided with through hole; Any one end of folder cylinder is provided with a chuck, with folder cylinder global formation; Chuck is flaring cylinder, and centre is provided with through hole; The other end of folder cylinder is also connected with a chuck, with folder cylinder global formation; Chuck is circular cylindrical cavity; Chuck is all consistent with the through-hole diameter of folder cylinder; In jaw face with 90 ° for separatrix is evenly distributed with four open slots.
The outside cylinder diameter 1mm less of the outside cylinder diameter of folder cylinder of further described chuck.
Open slot length on further described chuck is the summation of chuck and folder tube length degree.
On further described chuck, the groove width of four open slots is 2mm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model and fatigue tester.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.Low frequency electo hydraulic servocontrolled fatigue testing machine unit clamp, comprises chuck 1, folder cylinder 2 and chuck 3.
As shown in Figure 1, the structure of low frequency electo hydraulic servocontrolled fatigue testing machine unit clamp is: folder cylinder 2 is right cylinder cavity, and centre is provided with through hole.Any one end of folder cylinder 2 is provided with a chuck 1, with folder cylinder 2 global formation.Chuck 1 is flaring cylinder, and centre is provided with through hole.The other end of folder cylinder 2 is also connected with a chuck 3, with folder cylinder 2 global formation.Chuck 1 is circular cylindrical cavity, and centre is provided with through hole.The outside cylinder diameter 1mm less of the outside cylinder diameter of folder cylinder 2 of chuck 3.Chuck 1 is consistent with the through-hole diameter of folder cylinder 2.Chuck 1 on the surface with 90 ° for separatrix is evenly distributed with four open slots.Open slot length on chuck 1 is the summation of chuck 1 and folder cylinder 2 length.On chuck 1, the groove width of four open slots is 2mm.
In order to the function realizing this fixture better, if Fig. 2 is the structural representation of the utility model and fatigue tester: when this fixture reality uses, be that two covers use together, respectively clamped by the claw of fatigue tester, steel wire is then in fixture inside.
Using state of the present utility model: the through hole first steel wire being put into fixture, because chuck 3 is solid, can carry out spacing to the length stretched into.After putting into steel wire, claw fixture being put into fatigue tester clamps, and just can start experiment, greatly raise the efficiency, alleviate the burden of operator.
