Radial shearing limit experiment device for axis parts

Abstract

The invention discloses a radial shearing limit experiment device for axis parts. The radial shearing limit experiment device comprises a hydraulic cylinder, an upper fixed plate (6), a lifting plateand a control system, wherein a left right vertical plate and a right side vertical plate are respectively fixed on the left and right sides of a lower fixed plate, guiding mechanisms which are provided with lifting plates and move along the up-down direction are arranged on the left right vertical plate and the right side vertical plate, the upper fixed plate is fixed at the upper ends of the left right vertical plate and the right side vertical plate, and the hydraulic cylinder is fixed on the upper fixed plate; a connecting frame is fixed by a piston rod of the hydraulic cylinder, the lifting plate is fixed by the connecting frame, a left side guide rail flexible supporting device and a right side guide rail flexible supporting device are arranged on the lifting plate, a loading guide rail is fixed by the left side guide rail flexible supporting device and a right side guide rail flexible supporting device, a loading sliding block is mounted on the loading guide rail, an upper shearing seat is fixed on the loading sliding block, a butterfly bolt is screwed to the upper shearing seat, and an upper pin hole is formed in the upper shearing seat; and a lower pin hole is formed in alower shearing seat, the lower shearing seat is fixed on a swing plate through a pressure sensor, and the fixed position of the swing plate on the lower fixed plate can be adjusted. By utilizing the left side guide rail flexible supporting device and the right side guide rail flexible supporting device, the load can be completely borne by the butterfly bolt.

Description

technical field [0001] The invention relates to a shear limit test device, in particular to a radial shear limit test device for shaft parts. Background technique [0002] Safety production is the top priority of production enterprises, and some equipment has safety accidents and even casualties due to insufficient shear strength during design. Therefore, the strength of parts requires not only theoretical calculations, but also strength experiments. The current shear The experimental device for shear strength is complex in structure, difficult to operate, and high in cost. [0003] This application adopts automatic control, collects the data of pressure sensor in real time, and accurately measures the radial shear strength of shaft parts; The synchronous rod realizes the horizontal lifting of the loading guide rail connected by the double flexible device; the position of the upper shearing seat and the lower shearing seat can be adjusted to realize the coaxiality of the up...
