The second side surface is opposite to the first side surface.

[0030] The base 4 is also provided with a driving mechanism for pushing the second limiting member 7 to move toward the first limiting member 6;

[0031] Preferably, second limit members 7, accommodating holes 50 and driving mechanisms are provided on both sides of the first limit member 6, the two groups of second limit members 7 are opposite to each other, and the two groups of limit members simultaneously press the workpiece to be processed to balance the force of the first limit member and prevent the first limit member 6 from moving relative to the placement plate 5.

[0032] When it is necessary to perform cylindrical structure processing on the first processing block 2, firstly, the middle plate 1 of the workpiece to be processed is placed on the placement plate 5 by the manipulator 14 to support the middle plate 1 and the second processing block 3 is placed in the accommodating hole 50, and the first side surface of the middle plate 1 is opposite to the first limit piece 6, and then the second limit piece 7 is driven by the driving mechanism to move close to the first limit piece 6 to achieve the tightening of the middle plate 1. After the processing is completed, the driving mechanism removes the tightening of the second limit piece 7, and then the workpiece is taken out from the first limit piece 6 and the second limit piece 7 by the manipulator 14. During the removal process, the manipulator 14 drives the workpiece to squeeze the second limit piece 7 and drives the second limit piece 7 back to its original position, and then repeats the above steps.

[0036] Preferably, the lifting assembly 11 includes a lifting member 110, a fixed block 111 is fixed to the lifting end of the lifting member 110, a rotating shaft 112 is rotatably mounted on the fixed block 111, a slide groove 101 is opened on the abutting plate 10, the rotating shaft 112 extends into the slide groove 101, the rotating shaft 112 can rotate relative to the abutting plate 10 and can slide in the slide groove 101, the axis of the rotating shaft 112 is parallel to the axis of rotation of the abutting plate 10 relative to the mounting block 9, preferably, the slide groove 101 is a waist-shaped hole;

[0037] The lifting member 110 may be a cylinder or an electric cylinder in the prior art. In the present embodiment, the lifting member 110 is a cylinder. When the lifting member 110 is lifted or lowered, the pressing plate 10 rotates and the rotating shaft 112 slides in the slide groove 101. The pressing plate 10 rotates to press against the second stopper 7 or remove the constraint on the second stopper 7.
