[0022] Furthermore, the outer surface of the driving block 8 is provided with arc-shaped limit grooves 81 distributed in a ring array, and the outer surface of the driving block 8 is provided with toggle grooves 82 distributed in a ring array. A servo motor 83 is fixedly installed on the inner bottom wall of the operating table 1. The rotating rod 2 drives the annular clamping table 3 to rotate stably through the cooperation of the bearing, and the annular gasket 4 is provided to avoid contact between the mold and the annular clamping table 3.

[0023] Furthermore, the output shaft of the servo motor 83 is fixedly mounted with a rotating shaft 84 via a coupling, an annular mounting block 85 is fixedly sleeved on the outer surface of one end of the rotating shaft 84, and the outer surface of the annular mounting block 85 is fixedly connected with symmetrically distributed connecting rods 86, and the servo motor 83 drives the annular mounting block 85 to rotate and adjust via the rotating shaft 84.

[0024] Furthermore, one end of the connecting rod 86 is fixedly connected with an arc-shaped limit block 87, the outer surface of the arc-shaped limit block 87 contacts the inner wall of one of the arc-shaped limit grooves 81, and the outer surface of the annular mounting block 85 is fixedly connected with a guide sleeve 88. The cooperation between the arc-shaped limit block 87 and the arc-shaped limit groove 81 plays a role of limiting and fixing, and the rotation of the annular mounting block 85 also drives the guide sleeve 88 to rotate.

[0025] Furthermore, the inner wall of the guide sleeve 88 is movably sleeved with a guide block 89, and a support spring 810 is fixedly connected to the surface of one side of the guide block 89. One end of the support spring 810 is fixedly connected to the inner wall of one side of the guide sleeve 88, and the elastic force of the support spring 810 cooperates with the guide block 89 to perform telescopic movement.

[0026] Furthermore, a lever 811 is fixedly connected to the upper surface of the guide block 89, and a symmetrically distributed second servo electric cylinder 812 is fixedly installed on the upper surface of the operating table 1.

[0027] Furthermore, a movable sleeve 814 is slidably sleeved on the outer surface of the electric slide rail 813 , and a drill body 815 is fixedly mounted on the lower surface of the movable sleeve 814 . The electric slide rail 813 drives the drill body 815 to move and adjust through the movable sleeve 814 .

[0028] The rotary punching device realizes automated rotation adjustment of the circular mold, which not only has accurate rotation angle but also convenient operation, thus solving the problem of repeated disassembly and assembly of the mold when performing multiple punching operations on the circular mold. This is rather cumbersome and greatly reduces the mold grinding efficiency. Manual rotation of the mold is prone to angle deviation, resulting in inaccurate punching position.

[0029] Working principle: Step 1, place the mold to be punched above the annular clamping table 3, and prevent the mold from contacting the annular clamping table 3 through the setting of the annular pad 4, thereby preventing the drill body 815 from contacting the annular clamping table 3 and causing damage, drive the piston rod of the first servo electric cylinder 6 to extend, clamp and fix the circular mold through multiple arc-shaped clamping blocks 7, and then drive the drill body 815 to move according to the punching position through the cooperation of the electric slide rail 813 and the moving sleeve 814, start the drill body 815 after the movement is completed, and cooperate with the second servo electric cylinder 812 piston rod to retract and move to perform the punching operation;

[0030] Step 2: After the drilling is completed, the servo motor 83 is started to drive the rotating shaft 84 to rotate one circle. The rotation of the rotating shaft 84 drives the arc-shaped limit block 87 to rotate through the annular mounting block 85 and the connecting rod 86, so that the arc-shaped limit block 87 rotates and disengages from one of the arc-shaped limit grooves 81. At the same time, the annular mounting block 85 drives the guide block 89 to rotate through the guide sleeve 88. The rotation of the guide block 89 drives the driving block 8 to rotate through the lever 811 and the toggle groove 82;

[0031] Step three, the rotation of the driving block 8 drives the annular clamping table 3 to rotate through the rotating rod 2, thereby driving the clamped mold to rotate stably by ninety degrees. At the same time, the supporting spring 810 cooperates to drive the guide block 89 to shrink and reset with elastic force. When the lever 811 rotates to disengage from the lever groove 82, the arc limit block 87 rotates to contact and limit with another arc limit groove 81, thereby limiting and fixing the driving block 8, and the drilling operation can be continued at this time.
