Description

Technical Field

[0001] This utility model patent belongs to the field of tensile testing, and specifically relates to a T-shaped tensile testing fixture for non-standard specimens with locking holes. Background Art

[0002] A tensile test fixture is an essential fixture used with electronic universal tensile testing machines. Installed on the chuck, it's essential for conducting tensile tests. Currently, the tensile test fixtures used on mainstream electronic universal tensile testing machines, both domestically and internationally, are primarily wedge-shaped, self-locking tensile fixtures. Their maximum specimen width generally does not exceed 40mm, making them suitable only for tensile testing of standard specimens and some small, non-standard specimens. For non-standard specimens exceeding 40mm in width, custom fixtures are often used.

[0003] At present, the tensile test fixtures equipped on mainstream electronic universal tensile testing machines at home and abroad are mainly wedge-shaped self-locking tensile fixtures. The maximum clamping specimen width generally does not exceed 40mm, and can only be used for tensile tests on standard specimens and some small-section non-standard specimens; non-standard specimens with a width of more than 40mm mostly use homemade tensile fixtures.

[0004] At present, the tensile test fixtures for non-standard specimens have the following disadvantages: 1. The tensile test fixtures equipped on mainstream electronic universal tensile testing machines at home and abroad can only clamp non-standard specimens below 40 mm, and their scope of use is limited; 2. The locking function of the homemade tensile test fixtures for non-standard specimens is not flexible and reliable enough. Utility Model Content

[0005] In response to the problems of narrow clamping width and inflexible and unreliable locking function of existing non-standard specimen tensile test fixtures, the utility model provides a T-shaped non-standard specimen tensile test fixture with locking holes, which greatly increases the clamping width of non-standard specimens. At the same time, it can adopt self-locking function and bolt locking function for specimens of different widths, which is simple and flexible.

[0006] A T-shaped non-standard specimen tensile test fixture with a locking hole comprises a fixture body (1), a gasket (2), a bolt (3) and a nut (4); the fixture body (1) is composed of two T-shaped bodies, two clamping holes are provided on the T-shaped bodies, and the two T-shaped bodies are fixed by bolts (3) and nuts (4) passing through the clamping holes.

[0007] Furthermore, a gasket (2) is placed on the clamping hole.

[0008] Furthermore, the upper portion of the clamp body (1) is wedge-shaped and has teeth inside.

[0009] Furthermore, the clamp has a self-locking function and a bolt locking function.

[0010] Compared with the existing technology, the beneficial effects of the present invention are that, first, the T-shaped tensile test fixture with locking holes for non-standard specimens greatly increases the clamping width range of non-standard specimens, and the clamping range is within 80mm, which improves the capacity range of the testing machine and solves the deficiency that the existing tensile test fixture can only clamp non-standard specimens below 40mm.

[0011] Secondly, the T-shaped tensile test fixture for non-standard specimens with locking holes has both self-locking and bolt locking functions. Different locking functions can be used for specimens of different widths. It is not only simple and flexible, but also ensures the firmness of specimen clamping and the accuracy of the test.

[0014] The following is a specific example to illustrate the use of a T-shaped non-standard specimen tensile test fixture with locking holes. Technical personnel can understand other advantages of this utility model patent through this manual.

[0015] like Figure 1 As shown, the utility model provides a T-shaped non-standard specimen tensile test fixture with a locking hole, comprising a fixture body (1), a gasket (2), a bolt (3) and a nut (4), wherein the fixture (1) is composed of two T-shaped bodies, two clamping holes are provided on the T-shaped bodies, the gasket (2) is placed on the clamping holes, and the two T-shaped bodies are fixed by bolts (3) and nuts (4) passing through the clamping holes.

[0016] The clamp has a self-locking function and a bolt locking function. The self-locking function is achieved as follows: the clamp is installed in the chuck of the testing machine, the top of the clamp is wedge-shaped and has teeth inside. During the stretching process, the sample is subjected to a tensile force, and the clamp is subjected to a force opposite to the tensile force to achieve a self-locking function.

[0017] When in use, first connect the horizontal end of the clamp (1) to the clamp of the electronic universal tensile testing machine, place the non-standard sample between the two clamps, place a gasket (2) on the clamping hole, and use a bolt (3) and a nut (4) to pass through the clamping hole to fix the non-standard sample on the T-shaped non-standard sample tensile test clamp with locking hole.

[0018] The T-shaped tensile test fixture with locking holes for non-standard specimens can clamp a wide range of non-standard specimen widths, has a flexible and reliable locking function, and is simple and convenient to operate. It not only solves the shortcomings of the existing tensile test fixtures in terms of clamping width range and improves the testing capability of the testing machine, but also ensures the firmness of the specimen clamping during the tensile test and ensures the accuracy of the test.
