Problems solved by technology

In addition, after the test, the test piece is subjected to the action of the upper and lower pull force, and the metal debris on the surface will fall into the lower jaw device, and with the accumulation of time and the number of inspections, the garbage accumulated in the lower jaw device will become more and more The more, and it is difficult to clean, which seriously affects the service life of the machine
And every time the test is completed, it is necessary to manually remove the broken test piece located on the jaws, which also affects the work efficiency.

Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The universal testing machine includes an upper jaw located on the upper beam and a lower jaw located on the lower beam. The lower beam and the frame are fixed, and the upper beam is connected to the cylinder piston. Through the movement of the cylinder piston, the upper beam is driven to move relative to the lower beam. The vertical lifting movement achieves the purpose of tensile testing the specimen clamped by the upper and lower jaws. ...

Abstract

The invention discloses a lower transparent jaw mechanism for a universal testing machine and relates to the technical field of universal testing machines. The lower transparent jaw mechanism comprises a lower beam, wherein a through hole penetrating through the lower beam is formed in the lower beam, and a jaw device used for clamping a steel bar test piece is arranged in a part of space in the through hole. The mechanism not only is simple in structure, but also is easier to clamp and loosen the test piece, so working efficiency is greatly improved, and the service life of the instrument iseffectively prolonged.

Description

technical field [0001] The invention relates to the technical field of universal testing machines, in particular to a lower penetrating jaw mechanism for universal testing machines. Background technique [0002] At present, the universal testing machine is an instrument used to test building materials. The test items are not limited to tensile stress, tensile strength, breaking strength, breaking elongation, constant tensile stress, constant stress elongation, constant stress Value, tear strength, force value at any point, elongation at any point, pull-out force, adhesive force and peak calculation value, pressure test, shear peel force test, bending test, pull-out force puncture force, etc. A common universal testing machine includes a lower beam fixed to the frame, and an upper beam that can be lifted vertically relative to the lower beam. Jaw devices for clamping the upper and lower ends of the test piece are respectively installed on the upper beam and the lower beam. ...
