Description

technical field [0001] The invention belongs to the technical field of control, and relates to a stamping mechanical arm, in particular to a high-speed heavy-duty stamping mechanical arm control system. Background technique [0002] The robotic arm is an indispensable and important part of automation equipment. The efficient and safe work of the robotic arm is of great significance to production and life. At present, with the development trend of high-speed and heavy-duty mechanical equipment, higher and higher requirements are put forward for the stable performance and safety performance of the mechanical arm. At the moment of grabbing the heavy object, due to the acceleration and the effect of the heavy object itself, the mechanical arm is equivalent to an initial excitation, which will cause free vibration of the system and poor stability. [0003] Due to the above problems, after searching, Chinese patent literature discloses a punching height compensation device for a ...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many deficiencies in the punching height compensation device of the red punching manipulator. Due to the effect of gravity, the positive pressure between the telescopic system of the mechanical arm and the support base becomes larger, which causes a large friction force on the contact surface, which leads to the failure of the entire system. It evolves into a complex tribological system and induces self-excited vibration, which aggravates the wear of the manipulator and seriously damages the service life of the manipulator
