Two-degree-of-freedom transmission mechanism of explosion-proof robot

Abstract

A two-degree-of-freedom transmission mechanism of an explosion-proof robot comprises a supporting arm, a first degree-of-freedom transmission mechanism and a second degree-of-freedom transmission mechanism. The front end of the supporting arm is of a U-shaped structure, the rear end of the supporting arm comprises a supporting arm bottom plate, a supporting arm top plate and a supporting arm partition plate vertically installed between the supporting arm bottom plate and the supporting arm top plate, two symmetrical installation areas are formed, and anti-explosion servo motors and reversing mechanisms of the two degree-of-freedom transmission mechanisms are symmetrically installed in the two installation areas. According to the two-degree-of-freedom transmission mechanism, by means of a symmetrical installation mode, the structure is compact, the size of the supporting arm is reduced, and meanwhile, overall mass offset is avoided; the anti-explosion servo motors are used, so that the mechanism meets the IP65 protection grade requirement; the two reversing mechanisms are the same in structure, except reversing mechanism shells, other structural parts can be universal, and therefore interchangeability is good; the U-shaped structural design at the front end of the supporting arm avoids bending moment generated by asymmetry of one-way supporting; and the rear end of the supporting arm is in a shape similar to I-shaped steel, the structural strength is high, and the installation space is large.

Description

Technical field [0001] The present invention belongs to the technical field of multi-axis transmission, and more particularly to a two-degree-of-freedom transmission mechanism of an explosion-proof robot. Background technique [0002] With the development of industrial technology and the variety of application areas, toxic and harmful gases, radioactive materials, explosive substances, etc. have been unavoidable, and there is a big safety hazard in this working environment, and explosion-proof robots It can replace manual operations to achieve risk of dangerous goods, positioning, clamping, handling, assembly, etc., thoroughly realizing human-machine separation function. In actual work, due to the limitations of operating space, the outer shape of the explosion-proof robot is required to be as small as possible, and the control accuracy is as high as possible. [0003] The prior art plan is: a two-degree-of-aerated transmission structure composed of an explosion-proof motor and a...

AI Technical Summary

Problems solved by technology

The ordinary motor used in this scheme does not have explosion-proof performance, and the mechanism does not meet the requirements of IP65 protection level (dustproof and waterproof level), and because the motor is placed along the radial direction, its radial dimension is relatively large
