Abstract

The utility model discloses a fixture for a mechanical tensile test of a U-shaped electric power fitting. The fixture comprises a fixing pin, a U-shaped fixture body and a cylinder, wherein the fixing pin penetrates through coaxial through holes in the left and right ends of the U-shaped fixture body, and is connected with the U-shaped fixture body; and the cylinder is connected with the bottom end of the U-shaped fixture body. The fixture has the characteristics of safety, stability of a testing process and high accuracy of a testing result; and in addition, a slotted hole design is adopted for the fixture body, and the fixing pin can be easily taken out after test deformation.

Description

A kind of U-shaped electric armour clamp mechanical test extension test fixture
Technical field
The utility model relates to a kind of U-shaped electric armour clamp mechanical test extension test fixture.
Background technology
At present, link, prolongation ring etc. connects gold utensil, need to carry out mechanical test extension test when carrying out type approval test and quality testing, measures the physical disturbance load, mechanical damage load and the nominal failing load that connect gold utensil.Owing to being connected gold utensil shape, limit, be difficult to directly adopt the jaw of universal testing machine to be fixedly connected with gold utensil, therefore need to adopt special device that gold utensil is fixed on the jaw of universal testing machine.While adopting wire rope or hook etc. that gold utensil is fixed on to universal testing machine jaw and carries out tension test, easily cause gold utensil to be deviate from test process, bring many unsafe factors, and test result precision and repeatable poor, therefore need employing unit clamp badly, carry out mechanical test extension test.
The present invention is directed to above-mentioned shortcoming, propose a kind of U-shaped gold utensil, can detect link, prolongation ring etc. self with the connection gold utensil tensile property of hole shape structure, comprise physical disturbance load, mechanical damage load and nominal failing load.The present invention has the advantages that safety, test process are stable, test result precision is high, and because chuck body has adopted slotted hole design, after fixed pin test distortion, easily takes out.U-shaped fixture application object of the present invention is self connection gold utensil with hole shape structure, comprises link, U-shaped link, extends ring, duplex plate.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of U-shaped electric armour clamp mechanical test extension test fixture is provided, can detect link, prolongation ring etc. self with the connection gold utensil tensile property of hole shape structure, comprise physical disturbance load, mechanical damage load and nominal failing load.
For achieving the above object, the utility model adopts following technical proposals:
An electric armour clamp mechanical test extension test fixture, comprises fixed pin, U-shaped chuck body, cylinder, and described fixed pin, through the coaxial through-hole on two ends, U-shaped chuck body left and right, is connected with U-shaped chuck body, and cylinder is connected with U-shaped chuck body bottom.
Described U-shaped chuck body bottom is provided with threaded hole.
Described cylinder one end is provided with screw thread.
On described cylinder, be connected with back of the body cap.
Described back of the body cap is provided with internal thread.
Compared with prior art, the beneficial effects of the utility model are, the present invention has safety, test process is stable, test result precision is high feature, and because chuck body has adopted slotted hole design, after fixed pin test distortion, easily takes out.
