Brake positioning device for power-assisted mechanical arm

Abstract

The invention discloses a brake positioning device for a power-assisted mechanical arm, which comprises a fixed connection seat and a rotating arm mounted on the fixed connection seat through a driving main shaft. The driving main shaft includes a driving section connected to the rotating arm and a braking section extending outside the fixed connection seat. , the brake section is equipped with a brake positioning mechanism, the brake positioning mechanism includes a lock sleeve, a rotating disc fixedly connected with the drive shaft, a brake disc set on the drive shaft and located outside the rotation disc, and a brake disc mounted on the lock sleeve and capable of driving. The rotating disc is away from or attached to the braking part of the rotating disc, and the opposite surface of the rotating disc and the braking disc is provided with a stop structure that can be locked or engaged after being fitted. When in use, the brake part moves the brake disc away from or sticks to the rotating disc to achieve the purpose of braking the drive spindle and locking or releasing the brake. Therefore, the present invention can better meet the needs of simple, safe and reliable braking of the power-assisted manipulator, and effectively solve the problems of the brake device of the power-assisted manipulator such as fragility, loose lock, and complicated operation.

Description

technical field [0001] The invention is used in the field of power-assisted machinery, and in particular relates to a brake positioning device for a power-assisted mechanical arm. Background technique [0002] The power-assisted mechanical arm is a power-assisted device used to help workers reduce labor intensity during the process of moving objects, and at the same time, it also ensures that the possible injuries to workers caused by pure handling work are minimized. Each power-assisted mechanical arm includes a rotatable rotating arm, and the rotating arm needs to be positioned and locked in the process of rotating to carry the object, so that the carried workpiece remains stationary and locked to prevent drifting. Most of the positioning and locking mechanisms of the existing power-assisted mechanical arms are realized by locking bolts or latches. This positioning and locking mechanism is inconvenient to use and wears heavily on the rotating arm, and it is also difficult ...

Problems solved by technology

Most of the positioning and locking mechanisms of the existing power-assisted mechanical arms are realized by locking bolts or latches. This positioning and locking mechanism is inconvenient to use and wears heavily on the rotating arm, and it is also difficult to achieve positioning and locking at any position of the rotating arm.
