Mechanical tensile experiment testing device

Abstract

The invention discloses a mechanical tensile experiment testing device. A door-shaped frame is fixedly arranged at the top end of a base; a sliding lantern ring which is in sliding connection with the door-shaped frame is arranged on a vertical column of the door-shaped frame; a first oil cylinder and a second oil cylinder are fixedly arranged at the bottom end of the transverse beam of the door-shaped frame; the first oil cylinder and the second oil cylinder are arranged downwards vertically; the top end of a platform is fixedly arranged at the tail ends of the piston rods of the first oil cylinder and the second oil cylinder; the left end and the right end of the platform are fixed on a left sliding lantern ring and a right sliding lantern ring through a bracket; an upper clamp is fixedly arranged at the bottom end of the transverse beam of the door-shaped frame; the upper clamp is arranged between the first oil cylinder and the second oil cylinder; a lower clamp is fixedly arranged at the top end of the platform; the upper clamp and the lower clamp are coaxially arranged up and down; a load sensor is arranged at the bottom of the lower clamp; a detachable protection cylinder is arranged on the upper clamp; the upper clamp and the lower clamp are covered inside the protection cylinder. The mechanical tensile experiment testing device has the beneficial effects of being high in testing precision and high in security coefficient.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to a testing device for mechanical tensile experiments. Background technique [0002] The mechanical properties of materials refer to the mechanical characteristics of materials when they are subjected to various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity). The Chinese patent with the notification number CN203519423U discloses "a mechanical tensile test device", which lacks a certain protection mechanism between the upper chuck and the lower chuck. Once the material under test breaks, or from the upper and lower chucks It is easy to injure the experimenter, and the safety factor is low. A kind of mechanical tensile test device that can solve this problem still needs further research and development. Contents of the invention [0003] The object of the pr...

The Chinese patent with the notification number CN203519423U discloses "a mechanical tensile test device", which lacks a certain protection mechanism between the upper chuck and the lower chuck. Once the material under test breaks, or from the upper and lower chucks It is easy to injure the experimenters, and the safety factor is low. A mechanical tensile test device that can solve this problem still needs further research and development.
