Abstract

The invention belongs to the field of robots, and particularly relates to a safety device of a robot joint. Supporting legs serving as fixed ends are arranged on the two sides of a turnover table, thetwo sides of the turnover table are rotatably connected with the supporting legs, one side of the turnover table is connected with a servo drive motor mounted on the corresponding supporting leg on the same side, the other side of the turnover table is provided with a positive polygonal shaft end, one side or two sides of the positive polygonal shaft end are provided with power sources, the powersource on each side is arranged on the corresponding supporting leg on the same side, the power source on each side is connected with a self-locking sliding block through a connecting piece, each self-locking sliding block is in sliding connection with the corresponding supporting leg on the same side, the power sources drive the self-locking sliding blocks to do reciprocating motion, and self locking of the turnover table is realized through extrusion of the self-locking sliding blocks and the positive polygonal shaft end. Surface contact is adopted, the bearing is large, accurate positioning can be realized, the function that the power sources can be locked through working is realized, compared with an existing electric bolt, the friction and friction loss can be avoided, and the requirement on cleanliness is better met.

Description

technical field [0001] The invention belongs to the field of robots, in particular to a safety device for robot joints. Background technique [0002] At present, the safety device of robot joints is used for long-term passive mechanical locking and short-term motion electric unlocking for clean, vacuum, and industrial rotary joints. The mainstream is to use electric latches. However, the electric plug pin has particularly high requirements for machining accuracy and installation accuracy, and needs to process the inner hole; moreover, there is friction and wear, and the generation of dust is extremely unfavorable for improving the cleanliness of the system. Electric actuators are complex and not suitable for miniaturization. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the existing electric bolt type safety device, the object of the present invention is to provide a safety device for robot joints. [0004] The purpose of t...
