The first connecting block 200, the first piston rod 510, the cylinder assembly, the second piston rod 520 and the second connecting block 300 are sequentially connected to form an integral structure, and the integral structure can rotate relative to the hinge base 110; during operation, the cylinder assembly can move left and right through the extension and contraction of the first piston rod 510 and the second piston rod 520, and particularly, the cylinder assembly is not fixed, and since the hinge base 110 is fixed on the mounting plate 100, the cylinder assembly can move left and right relative to the mounting plate 100.

One end of the driving block 400 is hinged to the second connecting block 300 and the other end is provided with a rotating shaft 410.

Preferably, the driving block 400 is a vertical strip structure, the upper end of the driving block is hinged to the second connecting block 300, the lower end of the driving block is connected with the rotating shaft 410, the first piston rod 510 and the second piston rod 520 can stretch and retract, so that the second connecting block 300 can be pushed to move, the driving block 400 can be driven to rotate around the rotating shaft 410 when the second connecting block 300 is pushed, at the moment, the rotating shaft 410 is also driven to rotate by the driving block 400, and therefore the purpose of driving the object to rotate is achieved, the connecting rod structure is very ingenious, the structure is lighter, automatic control is facilitated, the functions of light weight, automation, cost and accurate positioning are achieved, and assembly and debugging are facilitated.

Preferably, the first cylinder 530 is provided with a first air port and a second air port, and the second cylinder 540 is provided with a third air port and a fourth air port, so that the operation of the cylinder assembly can be controlled by reasonably arranging the air path.

In the actual working process, when the connecting rod follow-up rotating mechanism is in the original point position, the driving block 400 needs to be in the vertical state, at this time, the first air port admits air and the second air port exhausts, so that the first piston rod 510 retracts to the first air cylinder 530, and simultaneously the third air port admits air and the fourth air port exhausts, so that the second piston rod 520 extends out of the second air cylinder 540, and the first air cylinder 530 and the second air cylinder 540 are ensured to be in the self dead point position, so that the original point position precision of the object is ensured, in brief, the original point precision of the mechanism can be ensured.

When the object needs to rotate counterclockwise, the second connecting block 300 needs to be pulled toward the cylinder direction, at this time, the first air port and the second air port keep the original state, so that the first cylinder 530 keeps still, meanwhile, the third air port exhausts air and the fourth air port admits air, so that the second piston rod 520 retracts into the second cylinder 540, at this time, the second piston rod 520 pulls the driving block 400 to rotate counterclockwise, and therefore the driving block 400 drives the rotating shaft 410 to rotate counterclockwise.

When the object needs clockwise rotation, needs second connecting block 300 to keep away from the cylinder direction, and first gas port exhaust and second gas port admit air this moment for first cylinder 530 stretches out, and the exhaust of third gas port and fourth gas port admit air simultaneously, makes in second piston rod 520 retracts the second cylinder 540, and second piston rod 520 pulling driving block 400 clockwise rotates this moment, thereby makes driving block 400 drive rotation axis 410 clockwise rotation.

It should be added here that since the rotation shaft 410 is kept stationary except for rotating when the second cylinder 540 pulls or pushes the second connecting block 300, the cylinder assembly rotates around the hinge base 110 by a certain angle, thereby maintaining the smooth movement of the whole structure; in addition, the first cylinder 530 and the second cylinder 540 cooperate with each other to achieve clockwise and counterclockwise rotation of the object.
