Abstract

The invention provides a vertical movement device of a truss manipulator. The vertical movement device of the truss manipulator comprises a truss, a cantilever, a travelling mechanism and a transmission mechanism. The truss and the cantilever are connected through the travelling mechanism, the cantilever is of a rectangular tubular structure, the three neighboring side surfaces of the truss are working surfaces, the travelling mechanism comprises linear guide rails or ball screws, and the transmission mechanism comprises racks or lead screws. The vertical movement device of the truss manipulator changes single-surface stress into symmetrical double-surface stress, overcomes the existing defect of uneven stress, reduces damage due to inertia force during rapid movement, enhances integral rigidity and prolongs the service life.

Description

technical field [0001] The invention belongs to the field of truss robots, in particular to a longitudinal movement device of a truss robot. Background technique [0002] Truss robots are now widely used in the production of various products, especially for the welding of large equipment, which has incomparable advantages. Generally, the electric welding machines carried on truss robots are heavy in weight, and have extremely high requirements for walking positioning accuracy. The traditional hanging arm structure often deforms after being used for a period of time due to uneven force, which brings great difficulties to high-precision walking positioning. In addition, maintenance is often time-consuming and labor-intensive, and the cost is high. Contents of the invention [0003] The problem to be solved by the present invention is to provide a longitudinally moving device for a truss robot with uniform force and strong rigidity. [0004] In order to solve the above tec...
