Quick-change device for tail end of electrically-driven permanent magnet adsorption type robot

Abstract

The invention discloses a quick-change device for the tail end of an electrically-driven permanent magnet adsorption type robot. The quick-change device comprises a main disc, a tool disc and a magnetic adsorption mechanism, a plurality of tool disc side magnets are fixedly arranged at one end of the tool disc, the main disc is of a hollow structure, and the magnetic adsorption mechanism is arranged in the hollow part of the main disc. The magnetic adsorption mechanism comprises a locking sleeve, a plurality of main disc side magnets and a driving device, the outer side face of the locking sleeve is rotationally connected with the inner wall of the main disc, the end face of one end of the locking sleeve is fixedly connected with the main disc side magnets, the other end of the locking sleeve is connected with the output end of the driving device, and the driving device is connected with the main disc. The main disc side magnets and the tool disc side magnets are arranged in an annular array mode, the driving device is used for driving the locking sleeve to rotate so that the main disc side magnets and the tool disc side magnets can be arranged in a staggered mode, existing pneumatic locking and unlocking are abandoned, mechanical structure locking is adopted, quick reloading is achieved, and electric unlocking is safe and reliable.

Description

technical field [0001] The invention relates to the field of quick-change devices for mechanical arms, in particular to an electric-driven permanent-magnet adsorption type robot end quick-change device. Background technique [0002] The existing manipulator realizes the switching of different execution tools by the manipulator through the quick change device, which has the following technical disadvantages: the self-locking system of the existing quick change device is unlocked by pneumatic drive, and the pneumatic tube needs to be exposed to the outside world. The pneumatic tube will rupture due to low-temperature embrittlement, which will cause the entire quick-change device to lose its function, or in the event of an electrical environment failure, the effective locking of the quick-change device cannot be maintained, which will cause the main plate of the quick-change device to be disconnected from the The tool disc falls off, damaging the end effector connected to the t...
