Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0018] The invention provides a clamp for a wire tensile testing machine, comprising:

[0019] The first block is provided with a through threaded hole 101, and the first side of the first block is provided with a plurality of semicircular first grooves 102 arranged in parallel;

[0020] The second block, the second side of the second block is provided with a plurality of semicircular second grooves 202 arranged in parallel, and a stud 201 extends vertically outward from the second block, so The stud 201 passes through the threaded hole 101, the free end of the stud 201 is located outside the threaded hole 101, and a nut is screwed on the free end of the stud 201, so that the first The block and the second block are fixed together, and each first groove 102 and each second g...

Abstract

Te invention provides a tensile testing machine fixture for wires. The tensile testing machine fixture comprises a first block and a second block, wherein the first block and the second block are fixedly connected through a nut. A plurality of parallel semicircular first grooves are formed in the first side of the first block. A plurality of parallel semicircular second grooves are formed in the second side of the second block. A cylindrical through hole is formed by each first groove and the corresponding second groove. In this way, multiple through holes are formed between the first block and the second block, the diameters of the through holes are different, and the through holes are used for carrying out tests on wires with different diameters. According to the tensile testing machine fixture, the through holes with different diameters are formed for the wires with different diameters, the wires are wound around a winding fixing part after penetrating the through holes and are fixed in a knotting mode or fixed in a bonding mode after passing through adhesive grooves, the wires are solidly fixed to the fixture and do not slip, the clamped ends of the wires are located in the through holes and are free of fractures, and therefore the accuracy of test results is improved.

Description

technical field [0001] The invention belongs to the field of testing equipment, in particular to a clamp for a tensile testing machine. Background technique [0002] When performing a tensile test on a wire, it is usually performed with the wire clamped on a fixture. The clamp usually clamps the wire with two planes in close contact, but some phenomena often occur during the test, such as the clamp is too loose, easy to slip, and the clamp is too tight, the clamping part will break, and both will Affect test results and waste wire. Contents of the invention [0003] In order to solve the above problems, the present invention provides a wire tensile testing machine fixture, comprising: [0004] A first block, which is provided with a through threaded hole, and the first side of the first block is provided with a plurality of semicircular first grooves arranged in parallel; [0005] The second block, the second side of the second block is provided with a plurality of semi...
