High-speed heavy-load mechanical arm

Abstract

The invention discloses a high-speed heavy-load mechanical arm. The high-speed heavy-load mechanical arm comprises a base body, a vertical column, a cantilever, a vertical driving assembly and a rotary driving assembly, wherein the vertical column is installed on the base body in a single-degree-of-freedom rotation mode along the central axis of the vertical column, the inner end of the cantilever is sleeved with the vertical column in a threaded mode and is perpendicular to the vertical column, and the vertical driving assembly comprises a vertical driving motor which is fixed on the base body and is in transmission fit with the vertical column; and the rotary driving assembly comprises a rotary driving motor, a vertical revolution rod and a revolution gear ring, the rotary driving motor is horizontally arranged, a shell of the rotary driving motor is rotationally installed on the base body in the mode that the shell rotates around the central axis of the vertical column in a single-degree-of-freedom mode, and an output shaft of the rotary driving motor is in transmission fit with the vertical revolution rod in a worm and gear mode. High-speed heavy-load work of the mechanical arm can be achieved, the cost is low, and the structure is simple and compact.

Description

technical field [0001] The invention relates to the field of robots, in particular to a high-speed heavy-duty mechanical arm. Background technique [0002] The mechanical arm of the robot 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. For example, in the process of stone processing and production, the mechanical arm needs to perform a large number of translational and rotational or compound movements. Although the drive of horizontal motion can easily achieve high-speed and heavy-duty drive, the driving force of the existing rotary heavy-duty drive is generally decelerated by motors. Hydraulic drive or hydraulic drive, although the hydraulic drive can meet ...

Problems solved by technology

For example, in the process of stone processing and production, the mechanical arm needs to perform a large number of translational and rotational or compound movements. Although the drive of horizontal motion can easily achieve high-speed and heavy-duty drive, the driving force of the existing rotary heavy-duty drive is generally decelerated by motors. Hydraulic drive or hydraulic drive, although the hydraulic drive can meet the heavy-duty drive, but the drive speed is relatively slow, and in the prior art motor with reducer drive structure, the high-speed braking inertia during rotation drive is relatively large, and the self-locking performance is poor. Easy to damage, and the precision of rotation stroke control is not high
