Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, set forth the present invention further, the present embodiment is implemented under premised on technical solution of the present invention, should understand these embodiments and only be not used in for illustration of the present invention and limit the scope of the invention.
As depicted in figs. 1 and 2, a kind of automatic punching machine with space cam, comprises spatial cam and paper tape conveying mechanism; Described spatial cam is provided with frame 1, space cam 2, roller 3, push rod 4, first helical gear 6, second helical gear 7 and the first drive motors 8, frame 1 is provided with base plate 22 and riser 23, riser 23 is arranged on the top of base plate 22, riser 23 is provided with shaft hole 20 and push-rod hole 21; Described space cam 2 is connected with riser 23 by rotating shaft 5, rotating shaft 5 is matched in clearance with the connection of shaft hole 20, cam path 10 is provided with in the middle part of space cam 2, cam path 10 cross section is rectangle, be provided with roller 3 above space cam 2, roller 3 bottom coordinates with cam path 10, and roller 3 top is connected with push rod 4 by welding, push rod 4 is connected with riser 23 by push-rod hole 21, and push rod 4 two ends are provided with drift 9; Described rotating shaft 5 left end is provided with the first helical gear 6, first helical gear 6 and is connected with the second helical gear 7 by engagement, and the second helical gear 7 is arranged on the main shaft of the first drive motors 8; Described paper tape conveying mechanism is provided with the second drive motors 12, the 3rd drive motors 24, drives circle wheel 13, first quarter moon plectane 14, thumb wheel 16 and jog dial 19, second drive motors 12 is arranged on the right side of spatial cam, and the 3rd drive motors 24 is arranged on the left side of spatial cam; Described second drive motors 12 is provided with and drives circle wheel 13, drive in the middle of circle wheel 13 and be provided with first quarter moon plectane 14, be provided with above first quarter moon plectane 14 and stir pin 15, drive above circle wheel 13 and be provided with thumb wheel 16, thumb wheel 16 is provided with oblong slots 17 and first quarter moon circular arc 18, first quarter moon circular arc 18 and first quarter moon plectane 14 are interference fits, stir pin 15 and coordinate with oblong slots 17, thumb wheel 16 center is provided with jog dial 19, and jog dial 19 is connected with paper tape 24; The driving circle wheel 13 that described 3rd drive motors 24 is arranged, thumb wheel 16, jog dial 19 are consistent with on the second drive motors 12 with paper tape 11.
Further, described second drive motors 12 and the 3rd drive motors 24 are synchronous motor.Synchronous motor can ensure that two paper tapes are when punching, and synchronously carry out, not the waste of generation time.
Further, coordinate with cam path 10 bottom described roller 3 for matched in clearance.Bottom of roller and cam path matched in clearance, can prevent stuck phenomenon effectively, ensures the normal operation of mechanism.
Further, the distance of described second drive motors 12 and the 3rd drive motors 20 is less than the width sum of push rod 4 and cam path 10.When pushrod movement is to most extreme position, drift can be effectively utilized, at perforating on paper tape, ensure that operating efficiency.
The present invention in use, should the paper tape of required punching be arranged on jog dial, open second, third drive motors simultaneously, second, third drive motors drives and drives circle wheel, at first quarter moon plectane with under the effect of stirring pin, thumb wheel is driven to make intermittent circular motion, thus drive paper tape also to do intermittent moving downward simultaneously, open the first drive motors, under helical gear engagement, drive space cam to rotate, drive roller by the cam path on space cam, roller drives push rod to do side-to-side movement, reaches working effect.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
