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...
