Abstract
The utility model relates to a special clamp, and particularly relates to the special clamp for a tension test of a torpedo transfer car ball head cable subassembly. The special clamp is a cylinder with a through hole, wherein a ball socket (1) matched with a ball head is arranged at one end of the cylinder, and an open slot (2) is arranged on the lateral wall of the cylinder. The clamp is the special clamp (utilizing the geometric spherical surface positioning principle) for the tension test of the torpedo transfer car ball head cable subassembly, so as to improve the precision of the tension test of the torpedo transfer car ball head cable subassembly, and remove the data distortion when a test piece is detected.
Description
Technical field
The utility model relates to a kind of unit clamp, in particular for the unit clamp of torpedo transfer car(buggy) bulb cable assembly tension test.
Background technology
Torpedo transfer car(buggy) bulb cable assembly 20 is made up of steel ball 21 and wire rope 22, and shown in Figure of description 2, the power that on pressing machine, produces through compacting steel ball 21 is tightened up sample.The existing directly mode of clamping steel ball 21 that is employed on the testing machine exists holding force can make steel ball 21 distortion and causes the problem of test figure distortion.In order to reduce, designed this test unit clamp owing to testpieces is installed the detection defect of data cause even the generation of distortion situation.The tension test of torpedo transfer car(buggy) bulb cable assembly is to measure the bulb cable assembly, under rated condition, and the test of the maximal destruction load during stretching.The main cause that influences torpedo transfer car(buggy) bulb cable assembly tension test precision is because the mounting means of testpieces the etc. when machining precision of precision of material tester grade, testpieces itself and detection.
The utility model content
The purpose of the utility model is: for improving the precision of the novel bulb cable assembly of torpedo transfer car(buggy) tension test; Eliminate testpieces and detect the big deviation of data appearance even the generation of distortion situation, design a kind of simple, easy for installation, the practical novel bulb cable assembly of torpedo transfer car(buggy) tension test unit clamp that connects.
Technical solution: a kind of torpedo transfer car(buggy) bulb cable assembly test unit clamp, for having the right cylinder of through hole, have the ball-and-socket (1) that matches with bulb at the one of which end, have open slot (2) at cylindrical sidewall.
Further, above-mentioned open slot (2) width is less than ball-and-socket (1) diameter.
Useful technique effect: these anchor clamps are a kind of torpedo transfer car(buggy) bulb cable assembly tension test unit clamps that utilize how much sphere positioning principles, have improved the precision of bulb cable assembly tension test, the distortion of data when eliminating the testpieces detection.

Fig. 2 is a bulb cable assembly tension test unit clamp working state schematic representation,
Wherein, 1: ball-and-socket, 2: open slot, 10: torpedo transfer car(buggy) bulb cable assembly test unit clamp, 20: bulb cable assembly, 21: steel ball, 22: wire rope.
Embodiment
Below in conjunction with Figure of description the utility model is done further explain.
See also Figure of description 1,2, a kind of torpedo transfer car(buggy) bulb cable assembly test unit clamp for having the right cylinder of through hole, has the ball-and-socket 1 that matches with bulb at the one of which end, has open slot 2 at cylindrical sidewall.
During test; At first torpedo transfer car(buggy) bulb cable assembly test unit clamp 10 is installed on the testing machine; The steel ball 21 of the seized testpieces lateral opening groove 2 through unit clamp 10 is fixed in the torpedo transfer car(buggy) bulb cable assembly test unit clamp 10; Ball-and-socket 1 and testpieces steel ball 21 test sphere are coincided, and wire rope 22 clampings of seized testpieces are installed on the testing machine, have so just avoided steel ball 21 be out of shape by holding force; The main axis and the loading axis that have guaranteed testpieces coincide, and can carry out the test of torpedo transfer car(buggy) bulb cable assembly.
For better implement the utility model, in process of the test, open slot 2 width are less than ball-and-socket 1 diameter, and steel ball 21 will be more stable in ball-and-socket 1 like this.
Utilizing loading sphere and test sphere to overlap warranty test spare fully when being pulled to power; Pulling force is carved the type anchor clamps from testing machine; Power is delivered on the steel ball surface of bulb cable assembly through torpedo transfer car(buggy) bulb cable assembly test unit clamp, promptly on the testpieces, not only plays the effect of fixation test part; Also simulate the actual stress of testpieces truly, can record the real crimp strength test figure of steel ball and wire rope.Through loading sphere and test sphere are overlapped fully, so just guaranteed that the main axis of testpieces and loading axis coincide, avoided the situation of steel ball distortion causing data distortion to take place.
Claims (2)
1. a torpedo transfer car(buggy) bulb cable assembly test fixture is characterized in that: for having the right cylinder of through hole, have the ball-and-socket (1) that matches with bulb at the one of which end, have open slot (2) at cylindrical sidewall.
2. will remove 1 described torpedo transfer car(buggy) bulb cable assembly test fixture according to right, it is characterized in that: open slot (2) width is less than ball-and-socket (1) diameter.
