Technical field
The present invention relates to a kind of clamping devices of screw fatigue test, belong to equipment Technology field.
Background technique
Fatigue test is mainly used for part material performance detection and standard component intensity detection, guarantee airplane parts quality and
Very crucial effect is played in flight safety, fatigue test is completed by fatigue tester, and fatigue tester is mainly used for surveying
Deposit category and its alloy material stretching, compression or drawing under room temperature state, press stress alternation fatigue behaviour test, test
When need to according to the shape of test specimen make be used for test specimen clamping special carrier, currently, for screw strength test collet it is each
Can only one screw of clamping, can be only done the test of a screw every time, since the screw of a batch needs to do more than one piece test specimen,
The problem of having resulted in screw fatigue test low efficiency, while the labor intensity of operator is also increased, and due to a folder
Head can only a kind of screw of specification of clamping, when the screw there are many specification needs to do fatigue test, it is necessary to make multiple folders
Head could complete test, thus considerably increase the cost of screw fatigue test.

Ailhead connector sleeve 4 and nail rod connector sleeve 5, ailhead connector sleeve 4 and nail rod are respectively equipped on the respective binding face of 2 joint place of link block
Test specimen screw 3 is installed on connector sleeve 5.
The clamping column 1 is cylindrical structure, and one end has threaded hole, and other end edge has chamfering, side
With annular groove.
The clamping column link block 2 is the block structure that middle part has square through hole, one lateral surface has stud, with
The opposite face of the lateral surface has through-hole, and the stud of clamping column link block 2 is to be threadedly coupled with the threaded hole of clamping column 1, clamping column connection
The through-hole of block 2 is that clearance fit is connect with ailhead connector sleeve 4 or nail rod connector sleeve 5.
The ailhead connector sleeve 4 is T shape cylinder table structure, and end face has through-hole, the through-hole of ailhead connector sleeve 4 and examination
Part screw 3 is clearance fit connection.
The nail rod connector sleeve 5 is T shape cylinder table structure, and end face has tapped through hole, the screw thread of nail rod connector sleeve 5
Through-hole is to be threadedly coupled with test specimen screw 3.
The intermediate link block 6 is the block structure that middle part has square through hole, band respectively on two opposite face
There is 1 through-hole, 2 through-holes of intermediate link block 6 are that clearance fit is connect with ailhead connector sleeve 4 or nail rod connector sleeve 5.
The invention has the advantages that a kind of clamping device structure of screw fatigue test provided by the invention is simple, operation side
Just, screw fatigue test efficiency 2 times or more can be improved, and screw fatigue test cost 80% can be reduced.
