Robot end execution protection mechanism with one-way buffering function

Abstract

The invention provides a robot end execution protection mechanism with a one-way buffering function. The robot end execution protection mechanism comprises a clamping mechanism. The clamping mechanism is fixed with a pneumatic claw. The upper end of the pneumatic claw is mounted under a lower flange plate by a pneumatic claw flange. The two ends of the lower flange plate are fixedly provided with linear bearings and the inner working face of each linear bearing fits a guiding limiting shaft. The parts of the guiding limiting shafts which pass through the lower flange plate are connected by two locking nuts. Compression springs pass through the guiding limiting shafts. One end of each compression spring is fixed with the outer end face of the corresponding linear bearing and the other end of each compression spring is fixed by a spring sleeve which is mounted under an upper flange plate. The parts of the spring sleeves and the linear bearings, which are located above the lower flange plate, are used as guiding limiting mechanisms of the upper and the lower ends of the compression springs, so that the whole end execution protection mechanism is of a rigid structure in the normal working state by the spring pre-tightening force. The parts of the guiding limiting shafts which pass though the upper flange plate are locked and fixed by two upper locking nuts. The upper flange plate is fixed with a robot arm and the pneumatic claw can receive the gas on the robot arm, so that the clamping control to the clamping mechanism can be realized.

Description

technical field [0001] The invention relates to a mechanical arm anti-collision protection mechanism, which is especially suitable for sorting mechanical arms. Background technique [0002] An industrial robotic arm is an automated mechanical device that can complete predetermined actions. Because its work content and appearance are similar to human arms, it is called an industrial robotic arm. The application of industrial robotic arms is very extensive, and it can be found in various stations such as point explosion, arc lighting, assembly, painting, cutting, handling, packaging and coding operations. For different working environments and work objectives, the robotic arm should undertake corresponding work content. [0003] The use of industrial robotic arms to improve the production process can ensure personal safety, reduce the harm caused by the working environment to the human body, reduce labor intensity, and improve production efficiency. At the same time, it can a...
