[0018] Step 2: Then, under the connection of the connecting shaft, the connecting shaft synchronously drives the eccentric wheel to rotate. Since the eccentric wheel rotates eccentrically, along with the rotation of the eccentric wheel, the maximum diameter part of the eccentric wheel fits the connecting push plate. Under the limit of the limit seat, the connecting push plate is continuously squeezed by the maximum diameter part of the eccentric wheel, so that the limiting sliding frame performs a linear motion under the limit of the limiting seat. Driven by the limiting sliding frame, the punch moves toward the direction of the workpiece until the maximum diameter part of the eccentric wheel vertically supports the connecting push plate. At this time, the movement of the limiting sliding frame reaches the position of the maximum stroke, so as to realize the punching of the workpiece, and then the waste material punched out is ejected by the first spring to realize the separation of the workpiece and the waste material. With the continued rotation of the eccentric wheel, the support of the connecting push plate by the maximum diameter part of the eccentric wheel begins to deviate, and the elastic reset of the limiting sliding frame is realized by the support of the fixed block by the second spring;

The operation of the second motor can drive the feeding suction cup to rotate, so as to realize the rotation adjustment of the punching position of the workpiece. Through the setting of multiple pushing mechanisms and limit punching components, the position movement of the workpiece is coordinated to realize multi-station punching of the workpiece. The punching power of the workpiece comes from the operation of the first motor, so that the workpiece can be rotated and fed at the same time, and the punching efficiency of the workpiece is higher.

[0020] Technical effects and advantages of the present invention:

[0021] (1) The present invention utilizes a configuration in which a rotary feeding mechanism and a punching device are matched, and multiple pushing mechanisms and a limit punching assembly are set to match the position movement of the workpiece to achieve multi-station punching of the workpiece, and the punching power of the workpiece comes from the operation of the first motor, so that the workpiece is rotated and fed while punching the workpiece is also achieved, making the punching efficiency of the workpiece higher. Compared with other punching machines, the punching machine only needs a smaller driver to obtain the same output, and a more intense energy exchange is performed between the rotary feeding mechanism and the punching device;

[0022] (2) The present invention utilizes a configuration in which the lift and the carrier plate are matched, and the operation of the lift facilitates the lifting and lowering of the carrier plate, thereby adjusting the height position of the workpiece so that the workpiece can be lowered to the position where the punching is required;

[0023] (3) The present invention utilizes a setting method in which a bolt rod and a first spring cooperate with each other, and through the threaded insertion between the bolt rod and the limiting sliding frame, the relative position between the punch head and the limiting sliding frame can be installed and fixed.

[0043] Working principle of the present invention:

[0044] First, the first motor 21 is operated to drive the main shaft to rotate, and then the main shaft drives the feeding turntable 23 and the driving gear 22 to rotate at the same time, and the driven gear 521 is meshed with the driving gear 22, so as to provide power for the rotation of the driven gear 521;

[0045] Then, under the connection of the connecting shaft 522, the connecting shaft 522 synchronously drives the eccentric wheel 523 to rotate. Since the eccentric wheel 523 rotates eccentrically, along with the rotation of the eccentric wheel 523, until the maximum diameter part of the eccentric wheel 523 fits with the connecting push plate 534, under the limit of the limit seat 531, the connecting push plate 534 is continuously squeezed by the maximum diameter part of the eccentric wheel 523, so that the limiting sliding frame 532 performs a linear motion under the limit of the limiting seat 531. Driven by the limiting sliding frame 532, the punch 5331 moves to The eccentric wheel 523 moves in the direction of the workpiece until the maximum diameter part of the eccentric wheel 523 vertically supports the connecting push plate 534. At this time, the movement of the limit slide frame 532 reaches the position of the maximum stroke, and the workpiece is punched. Then, the waste material punched out is ejected by the first spring 5333 to separate the workpiece from the waste material. With the continued rotation of the eccentric wheel 523, the support of the connecting push plate 534 by the maximum diameter part of the eccentric wheel 523 begins to deviate, and the elastic reset of the limit slide frame 532 is achieved by the support of the fixed block by the second spring.

[0046] Then, through the operation of the two-axis manipulator 41, the position of the workpiece is moved, and the displacement of the workpiece punching station is realized. Through the operation of the second motor 44, the feeding suction cup 43 can be driven to rotate, and the rotation adjustment of the punching position of the workpiece is realized. Through the setting of multiple pushing mechanisms 52 and limit punching assemblies 53, the position movement of the workpiece is coordinated to realize multi-station punching of the workpiece, and the punching power of the workpiece comes from the operation of the first motor 21, so that the workpiece can be rotated and fed while the workpiece is punched, which makes the punching efficiency of the workpiece higher.
