Embodiment Construction

[0038] Such as figure 1 As shown, a six-degree-of-freedom controllable parasitic mechanism type welding robot is composed of a host mechanism and a parasitic branch chain. The host mechanism is composed of a base bracket 04, a large arm 27, a middle arm 14, and a small arm 19. The parasitic mechanism It consists of six mutually independent branch chains. The specific structure and connection method are:

[0039] Such as figure 1 , image 3 As shown, the structure and connection method of the host mechanism are as follows: the upper part of the base bracket 04 is fixedly connected with the bearing support plate 02, the left side of the lower part of the base bracket 04 is fixedly connected with the left foot board 05, and the right side of the lower part of the base bracket 04 is fixedly connected with the right foot board 06. The purpose of connecting the two foot plates is to make the contact area between the base and the ground larger and the working process more stable; ...

Abstract

The invention relates to a six-degree-of-freedom controllable parasitic mechanism type welding robot. The six-degree-of-freedom controllable parasitic mechanism type welding robot is composed of a host mechanism and a parasitic mechanism. The host mechanism comprises a base bracket, a power mechanism, a large arm, a medium arm and a small arm. The parasitic mechanism is composed of six mutually independent branched chains. The host mechanism provides supporting and bearing loads for the whole structure. The six parasitic branches of the parasitic mechanism are used for controlling six degreesof freedom of the host mechanism. Two mechanisms are organically combined to complete welding work together. The six-degree-of-freedom controllable parasitic mechanism type welding robot refers to therelation between hosts and parasitism in the nature, and the host mechanism and the parasitic mechanism are organically combined to solve the problem that the load is too large in no-load and load processes of an existing welding robot, so that energy consumption and the cost can be reduced.

Description

technical field [0001] The invention relates to the field of mechanical industrial robots, in particular to a six-degree-of-freedom controllable parasitic mechanism welding robot. Background technique [0002] A welding robot is an automated robot that automatically runs on a fixed trajectory through a set program and performs welding work on a specific trajectory. Welding robots are widely used in automobile manufacturing, shipbuilding, military industry and other fields due to their advantages such as high work efficiency, good welding quality, and labor cost saving, which greatly improves the production efficiency of industrial manufacturing. In repetitive and dangerous working environments, liberate labor. The requirements of modern welding technology are getting higher and higher. Some welding processes even require a dust-free working environment to ensure welding quality. It is difficult to replace manual work. However, most of the robots widely used in the market ar...
