General type industrial robot additional shaft guide rail structure

Abstract

The invention discloses a general type industrial robot additional shaft guide rail structure comprising linear guide rails symmetrically mounted on the axial outer side surface of a guide rail base frame and a pinion and rack transmission mechanism arranged on one axial side of the guide rail base frame and powered by a servo motor with a protective cover. One side of the pinion and rack transmission mechanism is provided with a drag chain assembly in the axial direction. By means of the robot additional shaft guide rail, the better mechanical protection performance on an additional shaft internal structure can be achieved, pollution of media such as external splashing fluid and impurity particles to internal electrical and mechanical structures can be prevented, the structure can be stably and reliably applied to the occasions with the relatively bad working environment, the structure design is simple, production is convenient, and the appearance is beautiful. In addition, the linearguide rails, the servo motor and a pinion and rack are provided with complete protective covers, and the servo motor and the drag chain assembly are installed on the side face of the additional shaftguide rail, and equipment installation and daily maintenance and repairing are facilitated.

Description

technical field [0001] The invention relates to the technical field of a guide rail for an additional axis of a robot, in particular to a structure of a guide rail for an additional axis of a general-purpose industrial robot. Background technique [0002] Industrial robots are playing an increasingly important role in improving the flexibility and intelligence of manufacturing workshops. The most widely used industrial robots are in the manufacturing industry, especially in the automobile manufacturing industry. In the painting workshop of automobile manufacturing, the application of industrial robots has irreplaceable advantages in gluing, wiping, painting, cleaning, handling and assembly, surface treatment, quality and defect inspection and other stations. [0003] In the application of robot system integration, in order to increase the working flexibility of the robot and expand the working range, the additional axis guide rail is usually used as the standard configurati...

AI Technical Summary

Problems solved by technology

The structure of the guide rails for the additional axes of robots of different brands in the existing market is quite different, and each has its own advantages and disadvantages. The guide rail structure for the additional axes of industrial robots needs to have better installation and maintenance convenience, simple, stable and reliable structure, and better structural rigidity. and bending strength, the additional shaft guide rail has better protection performance for the internal structure, and the processing cost is lower

[0004] However, there are problems such as insufficient internal structure protection performance or inconvenient installation and maintenance in the structural design of the existing industrial robot additional axis guide rail.
