Rotary automatic mechanical arm

Abstract

The invention relates to a rotary automatic mechanical arm. The mechanical arm comprises an air cylinder, a positioning device, a fixed pneumatic claw and a following pneumatic claw. The upper end of the fixed pneumatic claw and the upper end of the following pneumatic claw are connected to the two sides of an installing plate. A rotating shaft penetrates the inner side of the fixed pneumatic claw, and the fixed pneumatic claw can synchronously rotate with the rotating shaft. One end of the rotating shaft is connected with the air cylinder through a rotary disc, and a positioning block matched with the positioning device is arranged at the other end of the rotating shaft. When the air cylinder lifts or contracts, the rotary disc rotates, the rotating shaft is driven to rotate, the rotating shaft rotates within a certain range through the positioning device, the fixed pneumatic claw is driven to rotate through rotation of the rotating shaft, and the following pneumatic claw is driven by the installing plate to rotate. Compared with the prior art, the rotary automatic mechanical arm is high in flexibility and suitable for various components of different specifications, it is guaranteed that a workpiece is closely attached to a positioning chuck of a machine tool through the following pneumatic claw, feeding is stable and reliable, and a good foundation is laid for finish machining of the machine tool.

Description

technical field [0001] The invention relates to the field of automation, in particular to a rotatable automatic manipulator. Background technique [0002] At present, with the gradual increase of labor costs, industrial automation applications are becoming more and more popular. In the machine tool processing line system, the attitude change of the workpiece is the basis for realizing the assembly line processing operation and improving the processing and manufacturing efficiency. In some of today's automated loading and unloading systems, a shelving table is generally placed between the machine tools, or a turning mechanism is installed to achieve various posture changes of the workpiece, which increases the movement of the manipulator and increases the work of manipulator loading and unloading. the beat. Existing rotary grippers are generally used for heavy-duty or complex-shaped workpieces such as cylinder blocks. However, these grippers are adjusted by multiple sensors...
