Quick-change device of robot end tool

Abstract

The invention relates to a quick-change device of a robot end tool. The quick-change device comprises an upper shell, a lower shell, a locking head and a quick-change disc, wherein a cavity is formed in the lower shell, a needle-shaped air cylinder is arranged at the upper part of the lower shell, the lower end of the needle-shaped air cylinder extends into the cavity, a conical head shaft is arranged at the lower part of the lower shell, the upper end of the conical head shaft extends into the cavity, a piston rod is arranged between the upper end of the conical head shaft and the needle-shaped air cylinder, and the upper end of the piston rod extends into the needle-shaped air cylinder and is in sliding connection with the needle-shaped air cylinder; a sliding chute with a downward opening is formed in the lower end of the locking head, the lower end of the conical head shaft extends into the sliding chute, the outer wall of the lower end of the conical head shaft is in sliding connection with the inner wall of the sliding chute, a plurality of working holes are formed in the side wall of the sliding chute, and steel balls which are used for being matched with the conical head shaft for locking are movably arranged in the working holes; and the quick-change disc is arranged on the outer side of the lower end of the locking head in a sleeving mode, and a limiting ring used for being matched with the steel balls for locking is arranged between the quick-change disc and the locking head. The quick-change device is simple in structure and capable of effectively reducing the influence of space interference on quick change of a robot.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a quick-changing device for a robot end tool. Background technique [0002] With the rapid development of industrial automation, industrial robots are widely used in manufacturing. The quick change device can realize the quick replacement of the end tool, which greatly improves the utilization efficiency of the robot, realizes "one machine with multiple functions", and makes the application of the robot more flexible. [0003] Most of the quick change devices currently on the market have quick change functions for various channels (mechanical connection, oil, gas, electricity, etc.), but they cannot meet the quick change of tools in narrow working spaces, such as sewing, gluing, deburring, etc. Therefore, it is necessary to design a micro-robot quick change device to meet the space interference problems encountered in production, while ensuring the load requirements and positioni...
