Multi-steering-engine driving mechanical arm

Abstract

The invention discloses a multi-steering-engine driving mechanical arm. The multi-steering-engine driving mechanical arm comprises a fixed base, a back arm, a middle arm and a forearm, the fixed baseis connected with the top of the back arm through a pitch joint, the bottom of the back arm is connected with the top of the middle arm through a first steering joint, the bottom of the middle arm isconnected with the top of the forearm through a second steering joint, and a clamping device is arranged at the bottom of the forearm; and the pitch joint comprises a pitch steering engine and a firstdriving shaft, the pitch steering engine is fixed on the fixed base, one end of a second driving shaft is connected to an output shaft of the pitch steering engine, and the other end of the second driving shaft is connected to the top of the back arm. According to the multi-steering-engine driving mechanical arm, the multi-steering-engine driving mechanical arm is similar to a human arm structure, has a higher supporting force, can achieve large-scale swing and precise positioning of the mechanical arm, and is suitable for the work scene of the light-load requirement.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a multi-rudder driven mechanical arm. Background technique [0002] At present, robotic arms are widely used in automated production in various industries. It can perform operations such as grasping and handling in accordance with prescribed procedures. However, most of the current robotic arms are directly installed with motors and their The deceleration device realizes the precise control of the robotic arm. The mechanical arm driven by the motor is usually too large in size and the motor power requirement is too high. It requires a lot of equipment space when grasping and transporting objects. Moreover, it is often impossible to achieve accurate positioning for objects with small mass and small size, so it is not applicable. For workplaces with light load requirements. Contents of the invention [0003] According to the deficiencies of the prior art, the purpose of...
