Abstract
A clamp specially used for a low-frequency electro-hydraulic servo fatigue testing machine is disclosed. The clamp comprises a clamping head (1), a clamping cylinder (2) and a jacket (3). The external cylindrical diameter of the jacket is 1 mm smaller than the external cylindrical diameter of the clamping cylinder, so that the clamp is provided with directivity and is convenient to install. The surface of the clamping head is evenly provided with four open slots by adopting the 90 degrees as a boundary, and therefore the clamp has elasticity, and a steel wire in the clamp can be tightly clamped when the clamp clamps the steel wire. The clamping head and the cylinder are provided with through holes and the jacket is free of through holes, thus limiting the length of the steel wire extending inside so as to perform spacing. The clamp has characteristics of simple configuration, using convenience and low manufacturing cost.
Description
Technical field
The present invention 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 to be a kind ofly mainly used in measuring the stretching under room temperature state of metal and alloy material thereof, to compress or draw, press the machine of the experiment on fatigue properties of stress alternation.In the axial fatigue performance test for metal material, the equipment adopting is at present electro-hydraulic servo fatigue experimental machine mostly.Fixture when fatigue experimental machine has Wedge gripping, horizontal sliding fixture and cylinder conventionally.Shortcoming is that plain clamp is heavier, and replacing is got up cumbersome, needs two people to operate together, both time-consuming, takes again manpower, inefficiency.
Prior art is compared, and the invention has the beneficial effects as follows:
1. the outside cylinder diameter of this fixture chuck, than the little 1mm of outside cylinder diameter of folder cylinder, can make this fixture have guidance quality like this, is convenient to install.
2. on this clamping fixture head surface, take 90 ° as separatrix, be evenly distributed with four open slots, can make like this fixture there is elasticity, when making clamp, steel wire in fixture can be clamped.
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 invention 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.
For solving the problems of the technologies described above the technical solution adopted in the present invention, be: 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, take 90 ° as separatrix, be evenly distributed with four open slots.
The outside cylinder diameter of further described chuck is than the little 1mm of outside cylinder diameter of folder cylinder.
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 invention.
Fig. 2 is the structural representation of the present invention and fatigue tester.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.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 formations.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 formations.Chuck 1 is circular cylindrical cavity, and centre is provided with through hole.The outside cylinder diameter of chuck 3 is than the little 1mm of outside cylinder diameter of folder cylinder 2.Chuck 1 is consistent with the through-hole diameter of folder cylinder 2.Chuck 1 surface is upper take 90 ° as separatrix, be 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 follow, realize the function of this fixture better, if Fig. 2 is the structural representation of the present invention and fatigue tester: during the actual use of this fixture, be that two covers are used together, respectively by the claw clamping of fatigue tester, steel wire is inner in fixture.
Use state of the present invention: first steel wire is put into the through hole of fixture, because chuck 3 is solid, can be carried out spacing to the length stretching into.Put into after steel wire, the claw of fixture being put into fatigue tester clamps, and just can start experiment, greatly raises the efficiency, and alleviates operator's burden.
