Abstract

The invention discloses a compression test fixture for a tensile testing machine. The compression test fixture for the tensile testing machine comprises an upper fixing plate and a lower fixing plate,wherein a first connector with a flange is arranged at the center of the outward surface of the upper fixing plate; a first pull rod, a second pull rod, a third pull rod and a fourth pull rod which use the first connector as an axial center and are symmetrical are arranged on the upper fixing plate; a second connector with a flange is arranged at the center of the outward surface of the lower fixing plate; a fifth pull rod, a sixth pull rod, a seventh pull rod and an eighth pull rod which use the second connector as an axial center and are symmetrical are arranged on the lower fixing plate; an upper clamping plate and a lower clamping plate which are parallel are arranged between the upper fixing plate and the lower fixing plate. The compression test fixture can solve the problem that thetensile testing machine cannot perform a compression test, is suitable for the compression tests of test pieces with different specifications, and is simple in structure, convenient to detach and mount, economical and practical.

Description

technical field [0001] The invention relates to the technical field of material detection, in particular to a compression test fixture used for a tensile testing machine. Background technique [0002] The general tensile testing machine is only equipped with a tensile sensor, so it can only apply tensile force, but the existing fixture of the tensile testing machine is difficult to apply pressure to the test piece, and cannot perform a compression test. Under the premise of not changing the tensile testing machine, if a compression test is required, a new type of compression test fixture needs to be designed to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a compression test jig for a tensile testing machine in order to overcome the deficiencies of the prior art. The compression test jig can solve the problem that the tensile testing machine cannot perform the compression test, and is suitable for the compression...
