Robot tool exchanging device driven by air pressure

Abstract

The invention discloses a robot tool exchanging device driven by air pressure, which is used for automatically exchanging end tools by a robot, belonging to the field of automatic machinery. The technical scheme in the invention provides a robot side module and tools side module, wherein the robot side module comprises a shell, a robot side connecting plate, a valve core, a cam, an upper limit loop, a spring, a lower limit loop, a spring cover plate, a cam retraction compressed air interface, a cam extension compressed air interface, a countersunk bolt and a valve core piston. The compressed air drives the valve core of the robot side module to move downwards, the cam retracts, and the robot side module and the tool side module can be separated; and the compressed air is utilized to drive the valve core of the robot side module to move upwards, the cam extends, and the robot side module and the tool side module are locked by the cam, thereby firmly connecting the robot end with the tool. The invention can realize reliable and convenient connection between the robot end and the tool, and has the advantages of simple control mode, self-locking function and high safety.

Description

Technical field [0001] The present invention involves a robot exchange tool, especially an air pressure -driven robot tool exchange device. Background technique [0002] The indispensable part of the modern manufacturing industry of industrial robots.In the fields of integrated circuit manufacturing, automobile welding, and automotive assembly, robots are playing an increasingly important role. [0003] In the field of robotics, using relatively universal robots to complete different tasks is a feasible way to reduce costs.For example, in the field of manufacturing processing, a robot can be used to complete different processes such as cutting, polishing, and welding.In these applications, a robot exchange tool device is required to enable robots to cooperate with different tools to complete different processes.The part of the robot switching tool device and the terminal connection of the robot is called the "robot side module", and the part that is combined with the tool is call...

Problems solved by technology

[0004] According to the search of the existing technology, it is found that the patent "manipulator fixture and tool exchange device in cutting and scribing equipment" (Patent No.: ZL02151074.1) applied by Shanghai Jiaotong University uses a manipulator to grasp the cutting torch and scribing torch , the versatility is not strong, it only meets the needs of the robot for plasma cutting and scribing of marine steel, and the safety is not enough. Once the system is accidentally powered off, the manipulator will suddenly release the tool, causing hazards

The patent "automatic tool exchange interface device" (patent number: ZL200710097421.0) applied by the Fourth Research Institute of the Second Artillery Equipment Research Institute requires both vacuuming to retract the spring pin and compressed air to separate the fixed end from the tool end. The system structure and control methods are relatively complex
