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.

The invention discloses a brake positioning device for a power-assisting mechanical arm. The brake positioning device for the power-assisting mechanical arm comprises a fixed connecting seat and a rotating arm, wherein the rotating arm is arranged on the fixed connecting seat through a driving spindle; the driving spindle comprises a driving section and a braking section; the driving section is connected with the rotating arm; the braking section extends to the outer side of the fixed connecting seat and is provided with a brake positioning mechanism; the brake positioning mechanism comprises a lock sleeve, a rotating plate, a braking plate and a braking component; the rotating plate is fixedly connected with the driving spindle; the braking plate sleeves the driving spindle and is positioned on the outer side of the rotating plate; the braking component is arranged on the lock sleeve and can drive the braking plate to be far away from the rotating plate or be adhered to the rotating plate; and locking mechanisms which can be locked or meshed after being adhered to each other are respectively arranged on surfaces, which face to each other, of the rotating plate and the braking plate. When the brake positioning device is used, the braking component drives the braking plate to be far away from the rotating plate or be adhered to the rotating plate, and the purpose of performing braking on the driving spindle and locking or releasing a brake is achieved. The brake positioning device can well meet requirements of simple, safe and reliable braking on the power-assisting mechanical arm; and the problem that a brake device of the power-assisting mechanical arm is easy to damage and complex in operation and cannot be locked tightly is solved.
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 ...
