Robot vibration test bench

Abstract

The invention discloses a robot vibration test bench, belongs to the technical field of vibration test, and aims to solve problems that the vibration amplitude of an existing vibration device is relatively tedious to adjust, the vibration frequency is generally adjusted by virtue of the rotating speed of a motor, the service life of the motor is influenced, and fixation and disassembly are not convenient enough. When a transmission gear rotates, a driving shaft is driven to further drive an eccentric roller to rotate, a lantern ring drives two groups of cross rods to move through the eccentric shaft, two groups of cross rods enable a rotating rod to reciprocate around a first fixed seat through a fixed rod, and finally, a vibration platform vibrates back and forth at the top of a workbench; and when the first telescopic air cylinder stretches out, an extrusion barrel moves backwards and is attached to the surface of a movable block, the movable block drives an eccentric shaft to move in an eccentric roller, finally, the position of a lantern ring in a movable groove is changed, the vibration amplitude is changed, and the vibration amplitude is conveniently adjusted.

Description

technical field [0001] The invention relates to the technical field of vibration testing, in particular to a robot vibration testing test bench. Background technique [0002] There are two types of vibration measurement in vibration testing: one is the vibration measurement of objects that cause noise radiation; the other is environmental vibration measurement; the most commonly used vibration methods can be divided into sinusoidal vibration and random vibration. The purpose of vibration testing is to simulate the product Various vibration environmental impacts encountered in transportation, installation and use environments are used to determine whether the product can withstand various environmental vibrations. [0003] At present, the existing vibration devices on the market can perform random vibration in all directions when testing the robot, but the adjustment of the vibration amplitude is relatively cumbersome, and the frequency of vibration generally depends on the s...

Problems solved by technology

[0005] The object of the present invention is to provide a robot vibration test bench, which solves the problem that the existing vibration device in the background technology can carry out random vibrations in various directions when testing the robot, but the adjustment of the vibration amplitude is relatively cumbersome. , and the frequency of vibration is generally adjusted by the speed of the motor during the test, resulting in long-term high-load operation that will affect the life of the motor. In addition, although the existing vibration device can firmly clamp the robot, But it is not convenient enough to fix and disassemble
