Anti-drawing test fixture with adjustable thickness

Abstract

The invention discloses an anti-drawing test fixture with adjustable thickness. The fixture is independently installed on two inclined and symmetric clamping parts and is characterized in comprising afixing fixture and a base plate, wherein the fixing fixture comprises a first flat plate and a second flat plate; the first flat plate and the second flat plate are in integral forming and are arranged in an L shape; one side of the first flat plate is fixedly installed on a clamping part, and the other side is provided with a first trough; the second flat plate is horizontally arranged; one sideof the base plate is provided with a first clamping part; and the first clamping part is adaptive to the first trough. The base plate can be increased or removed to flexibly regulate a clamping distance between two clamping parts. The fixture can be suitable for test materials of various size types, and has the advantages of convenience in operation, simple structure, low production cost, wide application prospect and excellent practicability.

Description

technical field [0001] The invention relates to a pullout test jig, in particular to a pullout test jig with adjustable thickness. Background technique [0002] At present, the traditional pull-out testing machine is dedicated to the mechanical performance test of steel strands and steel bars, and can measure the tensile strength, specified non-proportional extension strength, elastic modulus, elongation and other mechanical properties of steel strands. The traditional pull-out testing machine is generally equipped with a special ultra-thick jaw seat, which can completely contain the steel strand in the jaw seat when stretching, so as to ensure that the steel strand sample breaks in the middle, but the jaw seat equipped with this instrument is only It is suitable for steel strands and steel bars, so the opening size is usually within 5cm, and the width of the test block required for the tensile strength test of general concrete, steel structures, and wood structures should b...

Problems solved by technology

[0003] The electro-hydraulic servo steel strand comprehensive testing machine is expensive, and if it can only meet a single test requirement, it will inevitably cause waste; therefore, how to provide a simple structure, easy to operate, reliable fixtures, and can ensure The axis of the medium sample is on the same straight line as the direction of the force. At the same time, it is a technical problem to be solved urgently by those skilled in the art to be able to complete the pullout test fixture of various components without purchasing other testing machines.
