A robot arm with multi-angle precise control

Abstract

The invention discloses a multi-angle precision control type robot arm. The robot arm comprises a flange plate, a first telescopic device is mounted on the flange plate, the tail end of the first telescopic device is connected with a second telescopic device through a first servo motor, and the tail end of the second telescopic device is connected with a third telescopic device through a second servo motor. By adoption of the telescopic devices for replacement of tail end servo motors of the robot arm, high-precision screw rod type electric push rods high in self-locking performance can serve as the telescopic devices, and accordingly high structural strength is achieved, and the robot arm is high in tail end bearing capacity and suitable for application places high in tail end load requirement and small in mounting space. Multi-angle precision adjustment of tail ends of operating device mounting seats can be realized effectively while purchase cost of high-performance servo motors can be reduced effectively, so that high economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of robot arms, in particular to a multi-angle precisely controlled robot arm. Background technique [0002] The robot is an important automatic production equipment in the current industry. The traditional manipulator generally adopts three-coordinate linear movement or a rotary mechanical arm driven by a drive motor installed at the joint. The former has a large movement limit and cannot adjust the end position well Therefore, it can only be used for simple operations such as handling, and when the end of the robot is required to have more swinging degrees of freedom for various complex end processing tasks, it is required that the end of the robot's arm can be used in the required The latter can achieve this, but because the self-locking torque of the existing small servo motor is small, the control accuracy is low, especially when the end of the arm needs to carry a heavy load, so it is necessary to inven...
