A multi-angle robot arm with adjustable damping

Abstract

The invention discloses a multi-angle robot arm with adjustable damping, which comprises a bottom plate, the top middle of the bottom plate is rotatably connected with a rotating base, one end of the U-shaped bar is rotatably connected with a mechanical claw through a connecting mechanism, and the inner bottom of the installation groove corresponds to two An adjustment spring is embedded in the position between the two lifting bumps, and a block is installed on the top of the adjustment spring. The structure of the invention is scientific and reasonable, and it is safe and convenient to use. A connecting mechanism is provided to connect the U-shaped rod and the mechanical claw through the shaft body. The clamping block is stretched out by the action of the adjusting spring, which acts as a stable limit and ensures the stability of the mechanical claw after installation. When it needs to be disassembled, it is only necessary to turn the limit ring and slide along the lifting bump through the limit slider to make the limit The position slider can effectively cover the clamping block, realize the removal of the shaft body, improve the ease of disassembly of the shaft body, and solve the problem that the mechanical claws of the existing multi-angle robot arm are not convenient for quick disassembly and maintenance.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a multi-angle robot arm with adjustable damping. Background technique [0002] The robot arm, referred to as the mechanical arm, is an important production period device for automatic processing. Damping refers to the characteristic that the vibration amplitude of any vibration system gradually decreases due to external effects and the inherent reasons of the system itself. In order to reduce the shaking of the mechanical arm , friction plates are usually set at the swing connection and the rotation connection to improve the damping during relative motion and reduce the relative shaking of the parts. However, the damping of the rotating base of the multi-angle robot arm on the market is difficult to adjust, and it is easy to appear after long-term use. The damping is reduced, resulting in the shaking of the rotating base, which cannot guarantee the stable rotation and s...

Problems solved by technology

[0003] The present invention provides a multi-angle robot arm with adjustable damping, which can effectively solve the problem that the damping of the rotation base of the multi-angle robot arm currently on the market is difficult to adjust, and the damping is likely to decrease after long-term use, resulting in shaking of the rotation base. Due to the situation, the stable rotation and swing of the robot arm cannot be guaranteed, which reduces the working efficiency of the robot arm. At the same time, the connection between the existing mechanical claw and the U-shaped bar is fixed, and the disassembly of the mechanical claw is cumbersome, which is not conducive to maintenance and quick replacement.
