Abstract

The invention relates to the technical field of mechanical tests, in particular to a universal mechanical testing machine which comprises a driving part, a tension-compression transmission part, a side-compression transmission part, a clamping part and a rack, and the driving part is connected to the middle of the bottom of the rack in a matched mode; the driving part is in transmission connection with the tension-compression transmission part or the side-compression transmission part; the tension-compression transmission part is in transmission connection with the two clamping parts which are in relative sliding fit with the rack; the two ends of the side-compression transmission part are arranged on the rack in a sliding fit mode, and the two ends of the side-compression transmission part are arranged between the two clamping parts in a matched mode so as to carry out side part jacking and pressing on the to-be-tested piece clamped and fixed between the two clamping parts. The tension-compression transmission part and the side-compression transmission part are arranged in the device so that a material can be stretched or compressed, a top pressure test can be carried out on the material from the side part of the material, multiple test modes are provided, and different test requirements can be conveniently met.

Description

technical field [0001] The invention relates to the technical field of mechanical testing, and more specifically relates to a universal mechanical testing machine. Background technique [0002] Universal mechanical testing machine, a material testing machine integrating tensile, bending, compression, shearing, ring stiffness and other functions, is mainly used for mechanical performance tests of metal and non-metal materials. Ideal testing equipment for engineering quality supervision stations and other departments. However, most of the universal mechanical testing machines in the prior art are only used to perform tensile or compression tests on materials, and cannot perform top pressure tests on the sides of materials. Contents of the invention [0003] The purpose of the present invention is to provide a universal mechanical testing machine, which can effectively solve the problems in the prior art. [0004] The purpose of the present invention is achieved through the...
