Abstract

The invention discloses a mechanical arm modularized joint with force position perceiving function and relates to a mechanical arm modularized joint, which aims at solving the problems of large size, large power consumption and low integrated level of the current mechanical arm. A motor stator is fixedly mounted on a fixed shell; a second end cover is mounted in an output shell; the rigid wheel of a harmonic reducer is arranged in the second end cover; the second end cover is connected with the rigid wheel of the harmonic reducer and the fixed shell; a central hole wiring shaft is arranged inthe motor stator and the rigid wheel of the harmonic reducer; a cross roller bearing is mounted between the output shell and the fixed shell; the output shell is connected with the outer ring of a torque transducer; the flexible wheel of the harmonic reducer is mounted between the inner ring of the torque transducer and a connecting nut; a third end cover is mounted on the output shell; a limit stop is mounted on the third end cover; a rotating shaft is fixedly mounted in a motor rotor; a rotating magnetic ring opposite to a position transducer is fixedly sheathed on the rotating shaft; and the generator of the harmonic reducer is connected with the rotating shaft. The mechanical arm modularized joint with the force position perceiving function is used for forming multi-free mechanical arms with light weight through series connection.

Description

Technical field [0001] The invention relates to a modular joint of a mechanical arm. Background technique [0002] The robot arm is an important tool for the robot system to realize large-scale macro operations, and it has an important influence on the robot system's operating ability and operating level. Especially service robots and special operation robots, which have developed rapidly in recent years, have put forward higher requirements on operating arms. At present, mature robotic arms on the market have problems such as large weight, large size, high power consumption, and low integration, which limit the application of robotic arms and the integration with robot systems. Summary of the invention [0003] The present invention proposes a mechanical arm modular joint with force position sensing function to solve the problem of large weight, large volume, large power consumption, and low integration of the existing mechanical arm, which limits the application of the mechanic...
