Mechanical arm with strengthened structure

Abstract

The invention discloses a mechanical arm with a strengthened structure. The mechanical arm comprises a supporting pipe, a first installing plate, a rotation motor and a rotator. The rotation motor is arranged on the front face of the first installing plate. The rotation motor comprises a center rotation shaft concentric with the supporting pipe. The rotator is arranged at the front end of the center rotation shaft. The outer circle of the rotator is sleeved with a synchronous circular ring. A first bearing is arranged on the outer side of the synchronous circular ring. A second bearing is arranged on the outer circle of the first installing plate. A sleeve is arranged between the first bearing and the second bearing for connection. A first limiting clamp ring located at the front end of the first bearing is arranged at the front end of the sleeve. A second limiting clamp ring located at the rear end of the second bearing is arranged at the rear end of the sleeve. By means of the above manner and the mechanical arm with the strengthened structure, the weight of materials, a pneumatic clamp and the rotator is mainly borne by the synchronous circular ring, the structure strength is high, and the load of the center rotation shaft is reduced.

Description

technical field [0001] The invention relates to the field of mechanical arms, in particular to a structurally reinforced mechanical arm. Background technique [0002] With the development of intelligent manufacturing technology, robotic arms are more and more widely used in industrial production lines. The mechanical arm is usually installed at the feeding or retrieving station, which is convenient for automatic feeding or retrieving operations, and has good flexibility. [0003] The mechanical arm inevitably needs to rotate during use. When the shaft of the motor is directly connected to the load, the rotation accuracy is high. However, the load is likely to have adverse effects on the structure of the motor, and it is easy to cause the swing of the shaft, which affects the service life of the motor. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a mechanical arm with a reinforced structure, which reduces the...

[0003] The mechanical arm inevitably needs to rotate during use. When the shaft of the motor is directly connected to the load, the rotation accuracy is high, but the load is likely to have adverse effects on the structure of the motor, and it is easy to cause the swing of the shaft, which affects the service life of the motor.
