Processing and assembling method of public service robot driver

Abstract

The present invention relates to a robot driver, in particular to a processing and assembling method for a public service robot driver, which includes interference assembling a stop piece at one end of an inner shaft and one end of a hollow outer shaft; processing assembly holes on two elliptical driving wheels; and then The inner shaft is installed in the cavity of the hollow outer shaft, and the other end of the inner shaft protrudes from the other end of the hollow outer shaft; then a flat-bottomed annular groove is turned along the circumferential direction at the axial middle position of the flexspline blank; A ring-shaped V-groove is machined at the bottom of the groove along the circumferential direction; a row of teeth is respectively processed on both sides of the ring groove on the outer periphery of the flexspline; finally, two elliptical driving wheels equipped with inner and outer shafts are installed in the flexspline, so that the two ellipse The drive wheel is aligned with the two rows of teeth. The invention adopts the installation method of inner and outer shafts, which can provide two kinds of driving power and can change the transmission ratio of the reducer; at the same time, in terms of processing and assembly, the elliptical driving wheel is fixed by a coil spring, which is beneficial to reduce friction and avoid damage Oval drive wheels.

Description

technical field [0001] The invention relates to a robot driver, in particular to a processing and assembling method for a public service robot driver. 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, only articulated robots with different dimensions can be selected, such as arc welding robots, handl...

Problems solved by technology

[0003] In the current automated industrial production, the robot is the core. However, some operations of the robot require a relatively slow speed and require a large transmission ratio reducer to drive. The existing robots generally use articulated robots, and most of their transmission reduction mechanisms use Planetary plus cycloid reducer or harmonic reducer, because the driving devices of these reducers are mostly driven by a single shaft and a fixed gear set, so that the transmission ratio of the reducer is fixed, and it is difficult to meet the needs of robots for transmission ratio; And the coaxiality of these driving devices is not high enough in terms of processing and assembly
