Processing and assembling technology for intelligent robot joint device

Abstract

The invention relates to a robot, in particular to a processing and assembling technology for an intelligent robot joint device. The technology comprises the following steps: obtaining a U-groove type casing, and welding a first shaft on a bottom plate of the casing in the length direction of the U groove; fixedly mounting a shaft sleeve at one end of a connecting arm of a joint, and stretching one end of a second shaft into the position between two side plates from a bearing on one side plate; sleeving the second shaft with the shaft sleeve on the connecting arm from the position between the two side plates, and knocking the other end of the second shaft to enable the one end of the second shaft to penetrate the shaft sleeve to be in interference fit with a bearing on the other side plate; mounting a third shaft at the other end of the connecting arm through another bearing; connecting the first shaft, the second shaft and the third shaft with a speed reducing mechanism respectively. According to the technology, the first shaft and the second shaft are assembled on the special casing, the casing and the connecting arm can be driven by rotation of the first shaft to rotate horizontally, and the connecting arm can be driven by the second shaft and the third shaft to rotate vertically, therefore, the three-dimensional motion of a moving component can be realized through rotation of the three shafts.

Description

technical field [0001] The invention relates to a robot, in particular to a processing and assembling process for an intelligent robot joint device. Background technique [0002] Existing robots are mainly divided into two categories: Cartesian coordinate robots and articulated robots. The Cartesian robot is mainly composed of some linear motion units, drive motors, control systems and end manipulators. This kind of robot can be conveniently and quickly combined into wall-mounted, cantilever, gantry or upside-down Cartesian robots with different dimensions, various strokes and different load capacities for different applications. The articulated robot is mainly composed of some rotary motion units driving motors, control systems and end manipulators. Unlike Cartesian robots, articulated robots can be quickly combined into different dimensions. For different applications, such as arc welding robots, fixed articulated robots of different dimensions should be selected. [0...

Problems solved by technology

[0003] At present, the transmission modes of articulated robot joints mainly include rope pulley transmission, linkage mechanism transmission, belt transmission, chain transmission and gear transmission, etc., and some of these transmission components are easily deformed and the transmission is not accurate enough, such as belt transmission, rope pulley transmission, etc. , some of which have complex structures and difficult processing and assembly are not suitable for use in micro-miniature arc welding robots, such as linkage mechanisms, gear transmissions, etc.
