Robot arm convenient to dissemble and replace

Abstract

The invention discloses a robot arm convenient to dissemble and replace. The robot arm convenient to dissemble and replace comprises a main arm and an auxiliary arm, wherein multiple thread caps whichare uniformly distributed are arranged on the side surface of the main arm; a connecting piece is arranged on the top of the main arm; multiple first reset springs which are uniformly distributed arearranged inside the connecting piece; a clump weight is arranged on the tops of the first reset springs; and the tops of the first reset springs apply pressure to the clump weight. According to the robot arm convenient to dissemble and replace, the connecting piece is arranged and is fixed to the main arm in a clamping manner through the force of second reset springs and the first reset springs,which is applied to the clump weight and clamps; the connecting piece and the main arm are in threaded connection for reinforced treatment by the thread caps and a thread spindle in a fixation process; and the fixation manner of clamping not only facilitates the disassembly and replacement of the mechanical arm, but also can effectively reduce the vibration generated in the operation process of the mechanical arm and improves the working accuracy of the mechanical arm.

Description

technical field [0001] The invention relates to the technical field of robot arms, in particular to a robot arm that is easy to disassemble and replace. Background technique [0002] The robot arm is an auxiliary structure for the use of robots. Robots are widely used in modern industries. Robots can be used in all walks of life, especially manipulators. Different industries have different requirements for robot execution sensitivity, and some require high precision. Reaching micron-level precision movement, and some only need to simply perform a certain action. [0003] The existing robot arm is too complicated to install with the robot. When the robot arm is damaged, it takes a lot of time and energy for the staff to disassemble the robot arm, and the robot arm is prone to vibration during operation. As a result, the working accuracy is reduced. The range of movement of the mechanical claw of the general mechanical arm is limited, and the working range is small and inconv...

Problems solved by technology

[0003] The existing robot arm is too complicated to install with the robot. When the robot arm is damaged, it takes a lot of time and energy for the staff to disassemble the robot arm, and the robot arm is prone to vibration during operation. As a result, the working accuracy is reduced. The range of movement of the mechanical claws of general robotic arms is limited, and the working range is small and inconvenient to use.
