The above components are located below the carrier 11 (the plate 200).

Wherein, the lower connecting plate can be transversely arranged on the side wall of the translation frame 2 in a sliding way, and the power source can select the servo motor module.

The second driving oil cylinder 45 is fixedly arranged on the lower connecting plate and can transversely move along with the lower connecting plate. The second driving cylinder 45 is disposed corresponding to the working position, and a driving end of the second driving cylinder 45 extends downward in the vertical direction, and the driving end and the working position are on the same vertical axis. The driving end is drivingly connected to the base 471. In other words, the base 471 is supported by the second drive cylinder 45. The transmission connection mode is as follows: the ball spline 473 is rotatably inserted into the shaft hole of the pulley 475 and can move up and down with respect to the pulley 475; the transmission belt 476 is sleeved on the belt pulley 475 and the output shaft of the rotary driving member 472 to drive the belt pulley 475 and the ball spline 473 to rotate together; ball spline 473 passes through the lower end of pulley 475 to be connected to the drive end of second drive cylinder 45, and ball spline 473 passes through the upper end of pulley 475 to be connected to and support pedestal 471. Where ball spline 473 and rotary drive 472 are splines and a motor.

As shown in fig. 8, the lower punching module 413 and the lower nail pressing module 423 are symmetrically arranged on the upper surface of the base 471, and the base 471 can rotate around a vertical axis R by a set angle through the rotating driving member 472, so that the lower punching module 413 and the lower nail pressing module 423 can switch working positions with each other; the base 471 can be driven by the second driving cylinder 45 to vertically lift.

In the present embodiment, the base 471 is a cylindrical structure, and the punching lower module 413 and the pressing pin lower module 423 are located on the same diameter direction of the upper surface of the base 471. The base 471 is rotated 180 ° about a vertical axis by the rotary actuator 472, which switches the operating positions of the two lower modules.

When the punching lower module 413 is located at the working position, the driving end of the second driving oil cylinder 45 moves upwards to drive the punching lower module 413 to move upwards together. The lower punching module 413 is gradually close to the lower surface of the plate 200 in the height direction, at this time, the upper punching module 411 moves downward along the same vertical axis, and the two modules cooperate together to punch the plate 200, so as to form a through hole in the plate 200, thereby completing punching.
