Automatic locking mechanical arm

Abstract

The invention discloses an automatic locking mechanical arm. The automatic locking mechanical arm comprises a rack, a rotating mechanism and a locking mechanism, wherein the rotating mechanism comprises a base which is in sliding connection with the rack, an annular rotating base which is in bearing connection with the base, three telescopic rods which are in fixed connection with the annular rotating base, a first disk which is hinged to the lower ends of the three telescopic rods, a second disk and stand columns; and the locking mechanism comprises a sleeve which is fixedly arranged on the lower surface of the first disk, a cylinder which is sleeved by the sleeve in a sliding manner and connection pieces. According to the automatic locking mechanical arm, due to the fact that compressionsprings are designed between the first disk and the cylinder, the cylinder automatically locks grasping of claws under the elastic force action of the compression springs, and safety and reliabilityof the automatic locking mechanical arm are improved; and by adjusting the different lengths of the three telescopic rods, the first disk is driven to incline at all angles and in all directions, andtherefore the claws are driven to rotate at multiple angles, and completion of grasping operation of objects to be grasped on multiple planes and in all directions is achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology. More specifically, the present invention relates to a self-locking robotic arm. Background technique [0002] The mechanical arm can imitate certain movement functions of the human hand and arm, and is used to grab, carry objects or operate tools according to a fixed program; To protect personal safety, it is widely used in machinery manufacturing, metallurgy, electronics, light industry and other departments. [0003] The existing mechanical arm needs to continuously provide power to keep the claw body in the clamping state during the whole process from grabbing the object to completely putting the object down. Once the equipment has a circuit or other failure, the claw body will lose its clamping state, resulting in The grasped object falls off, which leads to the occurrence of safety accidents; the clamping mechanism between the claws of the mechanical arm is not firm, and when the heavy...

Problems solved by technology

[0003] The existing mechanical arm needs to continuously provide power to keep the claw body in the clamping state during the whole process from grabbing the object to completely putting the object down. Once the equipment has a circuit or other failure, the claw body will lose its clamping state, resulting in The grasped object falls off, which leads to the occurrence of safety accidents; the clamping mechanism between the claws of the mechanical arm is not firm, and when the heavy or irregularly shaped object is grasped and moved, the object is easy to fall from between the claws. Falling off will bring unnecessary troubles to industrial construction and affect the normal operation of industrial production
