Preferably, the mounting plate is provided with two limiting plates for restricting the swing rod to swinging in the same plane, and part of the swing rod is located between the two limiting plates.

Preferably, the cam is an eccentric wheel.

Preferably, one side of the mounting plate away from the swing rod is provided with a driving motor, the cam is fixedly mounted on a transmission shaft, and the driving motor drives and is connected with the transmission shaft.

Due to the adoption of the aforementioned solution, the swing type automatic mechanical arm according to the present invention can swing. Moreover, the swinging in two directions perpendicular to each other can be achieved in the case of using the reversing disc. The swing type automatic mechanical arm is simple in overall structure, operates flexibly, is suitable for occasions or processes with low precision requirements, and is low in cost and suitable for popularization and application.

Description of Embodiments The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in various different ways as defined and covered by the claims.

As shown in FIGs. 1-3, a swing type automatic mechanical arm provided by the present invention includes a mounting plate 1, a swing rod 2 with one end mounted on the mounting plate 1 through a rotating shaft, a cam for driving the swing rod 2 to swing and a reversing disc 4. The cam in this embodiment is an eccentric wheel 3, an extension spring 5 capable of restricting the swing rod 2 to always abutting against the peripheral wall of the cam is disposed between the swing rod 2 and the mounting plate 1, one end of the mounting plate 1 is connected and provided with an extension rod 6, and the side of the reversing disc 4 is provided with a cross groove 7 composed of two linear grooves perpendicular to each other; the center of the bottom of the cross groove 7 is provided with a through hole 8, the end of the mounting plate 1 is accommodated in any one of the linear grooves, and the extension rod 6 passes through the through hole 8; the end of the extension rod 6 is provided with a limiting check block 9, a compression spring 10 is disposed between the limiting check block 9 and the reversing disc 4, and the compression spring 10 sleeves the extension rod. The mounting plate 1 is provided with two limiting plates 11 for restricting the swing rod 2 to swinging in the same plane, and part of the swing rod 2 is located between the two limiting plates 11. One side of the mounting plate 1 away from the swing rod 2 is provided with a driving motor, the cam is fixedly mounted on a transmission shaft, and the driving motor drives and is connected with the transmission shaft.
