[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The utility model provides a punching device for the production of pneumatic actuator cylinder heads, including a punching table 1 and a U-shaped frame 2 connected to the top of the punching table 1. The U-shaped frame 2 is connected to a punching mechanism for punching the cylinder head. The punching mechanism includes a hydraulic cylinder 3, a motor 4, a lifting plate 8, a rotating plate 13, multiple push-pull plates 14, multiple sliding blocks 15, and multiple punching rods 9. The hydraulic cylinder 3 is used to drive the lifting plate 8 to rise and fall. The hydraulic cylinder 3 is connected to the top of the U-shaped frame 2, and the U-shaped frame 2 provides good support and fixation for the hydraulic cylinder 3. The motor 4 is used to drive the rotating disk 13 to rotate. The two ends of the push-pull plate 14 are connected to the rotating disk 13 and the sliding block 15. The sliding block 15 is movably connected to the lifting disk 8. The top of the punching rod 9 is connected to the sliding block 15. The motor 4 drives the rotating disk 13 to rotate. The rotating disk 13 synchronously applies tension or thrust to multiple push-pull plates 14, so that the sliding block 15 moves back and forth on the corresponding sliding hole 16. The sliding block 15 synchronously drives the corresponding punching rod 9 to move, that is, the spacing between adjacent punching rods 9 is controllable, which can meet the processing of cylinder heads of different sizes and has strong applicability. The lifting disk 8 is connected with a positioning mechanism for positioning the cylinder head.

[0023] During processing, the cylinder head is placed on the top of the punching table 1, and the hydraulic cylinder 3 drives the connecting frame 5, the support plate 7, and the lifting plate 8 to move downward, and simultaneously drives multiple punching rods 9 to move downward, so as to realize a one-time punching operation on the end edge 12 of the cylinder head with high efficiency.

[0024] The punching mechanism also includes a connecting frame 5 and a support plate 7. The connecting frame 5 is connected to the top of the support plate 7. The support plate 7 is fixedly connected to the lifting plate 8. The power output end of the hydraulic cylinder 3 is connected to the connecting frame 5.

[0025] The motor 4 is connected to the top of the support plate 7 , and the output shaft of the motor 4 is connected to the rotating disk 13 . The rotating disk 13 is rotatably connected to the top of the lifting disk 8 , which can improve the rotation stability of the rotating disk 13 .

[0026] The support plate 7 is connected to a locking mechanism for locking the rotating disk 13. The locking mechanism includes a cylinder 6, a positioning head 17, and multiple positioning slots 18. The cylinder 6 is fixed to the support plate 7, and the power output end of the cylinder 6 is connected to the positioning head 17. The positioning head 17 matches the positioning slots 18, and the positioning slots 18 are set at the top of the rotating disk 13. When the rotating disk 13 is in a suitable position, the cylinder 6 drives the positioning head 17 to move downward, so that the positioning head 17 connects to the corresponding positioning slots 18, thereby locking the rotating disk 13, preventing the push-pull plate 14, the sliding block 15, and the punching rod 9 from loosening, and improving the punching accuracy.

[0027] The lifting plate 8 is provided with a plurality of sliding holes 16 , and the sliding blocks 15 are slidably connected to the sliding holes 16 . The sliding blocks 15 can slide in the sliding holes 16 , thereby improving the stability of the movement of the punching rod 9 .

[0028] Both ends of the push-pull plate 14 are connected to the sliding block 15 and the rotating disk 13 .

[0029] The positioning mechanism includes a positioning plate 10, a plurality of pressure blocks 20, a plurality of pressing surfaces 21, a plurality of guide posts 22, a plurality of springs 23, and a plurality of slide grooves 24. The positioning plate 10 is connected to the bottom of the lifting plate 8, and the slide groove 24 is set at the bottom of the positioning plate 10. The pressure block 20 is slidably connected to the slide groove 24. The guide post 22 passes through the pressure block 20. The spring 23 is sleeved on the guide post 22, and both ends of the spring 23 are connected to the pressure block 20 and the positioning plate 10. The pressing surface 21 is set on the pressure block 20. During operation, the downward movement of the lifting plate 8 drives the positioning plate 10 to move downward, and the pressure block 20 presses on the top of the cover body 11. The pressing surface 21 slides relative to the cover body 11, causing the pressure block 20 to slide in the slide groove 24. The spring 23 is gradually compressed, and the pressure applied to the cover body 11 is also increased. This can not only achieve the centering of the cylinder head and put the cylinder head in a suitable processing position, but also achieve fixed locking, improve the stability of the cylinder head, and provide a good foundation for subsequent punching operations.

[0030] The guide post 22 is connected to the slide groove 24 , and the pressing block 20 is slidably connected to the guide post 22 . The cooperation between the guide post 22 and the slide groove 24 enables the pressing block 20 to move back and forth stably and avoids skewing or deviation.

[0031] The pressing surface 21 is tilted and smooth, which can reduce friction with the cover 11 .

[0032] The punching table 1 is provided with a plurality of discharge holes 19 , which can prevent the tip of the punching rod 9 from directly contacting the punching table 1 , thereby protecting the punching rod 9 , and the residue generated during punching is discharged from the discharge holes 19 .

[0033] During the punching operation, the positioning mechanism first limits and fixes the cylinder head. At this time, the punching rod 9 has not yet contacted the end edge 12. The lifting plate 8 moves further downward, the pressure block 20 moves further, the spring 23 is further compressed, and then the punching rod 9 punches the end edge 12.

[0034] Working principle: The cylinder head is placed on the top of the punching table 1, and the hydraulic cylinder 3 drives the connecting frame 5, the support plate 7, and the lifting plate 8 to move downward, and simultaneously drives the multiple punching rods 9 to move downward, so as to achieve a one-time punching operation on the end edge 12 of the cylinder head. At the same time, during the descent of the punching rod 9, the positioning plate 10 also moves downward synchronously, the pressure block 20 presses on the top of the cover body 11, the pressing surface 21 slides relative to the cover body 11, the pressure block 20 also moves synchronously, the spring 23 is gradually compressed, and the pressure applied to the cover body 11 gradually increases, which can not only achieve centering processing, but also improve the stability of the cylinder head, facilitating subsequent punching operations. When facing cylinder heads of different sizes, the motor 4 can drive the rotating disk 13 to rotate, and the rotating disk 13 synchronously applies thrust or pull force to the multiple push-pull plates 14, so that the multiple sliding blocks 15 slide in the corresponding sliding holes 16. The sliding blocks 15 drive the punching rods 9 to move, so that the spacing between adjacent punching rods 9 can be controlled, thereby meeting the processing of cylinder heads of different sizes. When the punching rod 9 is in a suitable position, the cylinder 6 drives the positioning head 17 to move downward, so that the positioning head 17 is connected to the corresponding positioning groove 18, thereby locking and fixing the rotating disk 13, preventing the punching rod 9 from loosening, and improving the punching accuracy.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
