Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further set forth the present invention, the present embodiment is implemented under taking technical solution of the present invention as prerequisite, should understand these embodiment and only be not used in and limit the scope of the invention for the present invention is described.
As depicted in figs. 1 and 2, a kind of automatic punching machine with space cam, comprises spatial cam and paper tape conveying mechanism; On described spatial cam, be provided with frame 1, space cam 2, roller 3, push rod 4, the first helical gear 6, the second helical gear 7 and the first drive motors 8, in frame 1, be provided with base plate 22 and riser 23, riser 23 is arranged on the top of base plate 22, is provided with shaft hole 20 and push-rod hole 21 on riser 23; Described space cam 2 is connected with riser 23 by rotating shaft 5, the matched in clearance that is connected to of rotating shaft 5 and shaft hole 20, space cam 2 middle parts are provided with cam path 10, cam path 10 cross sections are rectangle, space cam 2 tops are provided with roller 3, and roller 3 bottoms coordinate with cam path 10, and roller 3 tops are 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 4; Described rotating shaft 5 left ends are provided with the first helical gear 6, the first helical gears 6 and are 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; On described paper tape conveying mechanism, be provided with the second drive motors 12, the 3rd drive motors 24, drive circle wheel 13, first quarter moon plectane 14, thumb wheel 16 and jog dial 19, the 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; On described the second drive motors 12, be provided with and drive circle wheel 13, in the middle of driving circle wheel 13, be provided with first quarter moon plectane 14, first quarter moon plectane 14 tops are provided with stirs pin 15, drive circle wheel 13 tops to be provided with thumb wheel 16, on thumb wheel 16, be provided with oblong slots 17 and first quarter moon circular arc 18, first quarter moon circular arc 18 is interference fits with first quarter moon plectane 14, stirs pin 15 and coordinates with oblong slots 17, thumb wheel 16 centers are provided with jog dial 19, and jog dial 19 is connected with paper tape 24; The driving circle wheel 13, thumb wheel 16, the jog dial 19 that on described the 3rd drive motors 24, arrange are consistent with on the second drive motors 12 with paper tape 11.
Further, described the second drive motors 12 and the 3rd drive motors 24 are synchronous motor.Synchronous motor can ensure that two paper tapes, in the time of punching, synchronously carry out, not the waste of generation time.
Further, described roller 3 bottoms coordinate with cam path 10 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 the second drive motors 12 and the 3rd drive motors 20 is less than the width sum of push rod 4 and cam path 10.In the time that pushrod movement arrives extreme position, can effectively utilize drift, at perforating on paper tape, ensure operating efficiency.
The present invention in use, the paper tape of required punching should 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 and stirring under the effect of pin, drive thumb wheel to make intermittent circular motion, thereby 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.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being made up of above technical characterictic.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.
