The cutting elongated groove 15 on main shaft 12, partial gear 16 probe into drive rack 17 in elongated slot 15, can prevent main shaft machine
Structure rotates and influences the engagement of partial gear 16 and rack 17, increases the stability of card punch entirety.
Partial gear is a kind of driving member in mechanical device, and driving gear only makes one or several teeth, according to fortune
The gear teeth being meshed with driving wheel are made in the requirement of dynamic time and idle hours on the driven wheel, and rest part is locking circular arc.
When two gear teeth enter engagement, as gear drive, toothless part keeps driven wheel static by the positioning of locking circular arc.
Incomplete gear mechanism is simple in structure, manufacture is easy, reliable operation, and driven wheel run duration and quiescent time can be
Variation in wide range.
When rocking handle 23 drives shaft 22 to rotate, partial gear 16 rotates, former using the intermittent action of partial gear
Reason drives mainshaft mechanism to move up and down by rack 17, and punch 19 can complete punching action.
The feed bar 5 is as shown in figure 4, including outer barrel 51, little spring 52, sliding bar 53, unilateral bearing 54, idler wheel
55；51 top of outer barrel is solid round rod, and lower part is cylindrical shape, and the cylinder on 53 top of sliding bar can be in outer barrel 51 in an axial direction
Free to slide, little spring 52 is mounted on the middle part of sliding bar 53, and one end is fixedly mounted on 51 bottom of outer barrel, and the other end is by sliding bar
53 press to the lower part of outer barrel 51, and the round bar of 53 lower part of sliding bar is fixed in the inner ring of unilateral bearing 54, outside unilateral bearing 54
Ring installs idler wheel 55, and idler wheel 55 can be in the lower end single direction rotation of sliding bar 53.When the pressure change that 55 bottom of idler wheel is subject to,
The length of feed bar 5 can change.
Operating process：
By taking cardboard perforating as an example, cardboard is placed on workbench 4, rotating nut 3, workbench 4 is adjusted to suitable height
Degree, the i.e. upper surface of cardboard and 55 contact of idler wheel of 5 lower end of feed bar are appropriate, and the course of work is divided into following steps：
1, the card punch working condition A of a kind of adjustable spacing, as shown in fig. 6, rocking handle 23 is sleeved in shaft 22, a hand
Quick shaking shakes handle 23, then shaft 22 drives partial gear 16 and driving cam 20 to rotate, 16 toothed portion of partial gear
After being contacted with the rack 17 of mainshaft mechanism, mainshaft mechanism is lifted up by partial gear 16, and convex shoulder 14 compresses main shaft spring 13,
Mainshaft mechanism is moved up along the circular hole and 10 top circular hole of outer cover of support plate 18, at this time the protrusion of driving cam 20 and
Feed bar 5 contacts, and pushes the lower end of feed bar 5 to right side, when idler wheel 55 moves right, unilateral bearing 54 is can to rotate
, so idler wheel 55 is rotated on cardboard, cardboard does not move.
2, the card punch working condition B of a kind of adjustable spacing, as shown in fig. 7, partial gear 16 continues to rotate, main shaft machine
Structure continues to move up, and the circular arc of the base circle portion of driving cam 20 is gradually contacted with feed bar 5, under the action of spring 6, feeding
5 lower end of bar is moved to the left, and unilateral bearing 54 cannot rotate, and under the action of frictional force, idler wheel 55 drives cardboard to be moved to the left, complete
It is moved at primary feed.
3, the card punch working condition C of a kind of adjustable spacing, as shown in figure 8, partial gear 16 continues to rotate, main shaft machine
Structure is pushed to close to peak.The circular arc of the base circle portion of driving cam 20 is still contacted with feed bar 5, and feed bar 5 keeps original
Position, cardboard are motionless；Partial gear 16 and the engagement of rack 17 disengage moment, and mainshaft mechanism restores force effect in main shaft spring 13
Under, it moves down rapidly, generates larger impact force action on cardboard, cardboard is punctured, complete primary punching, as shown in Figure 9.
4, the card punch working condition D of a kind of adjustable spacing, as shown in figure 9, continuing to rotate rocking handle 23, partial gear 9
Mainshaft mechanism can be lifted again, while driving cam 20 elapses to the right the lower end of feed bar 5, but because of unilateral bearing 5
Effect, idler wheel 55 scroll right on cardboard, and cardboard does not move, and idler wheel 55 is moved to right side, returns to position shown in fig. 6,
Auto-feed for cardboard next time is ready.
Above step is repeated, equidistant hole will be continuously got on cardboard.
In the present apparatus, changing the method for punching distance is：
Adjust position of the axis pin 8 in sliding slot 9.Axis pin 8 drives feed bar 5 to move up, and is closed according to the geometry that feed bar 5 is swung
It is found that idler wheel 55 moves right, distance reduces for system；Axis pin 8 drives feed bar 5 to move down, and the spacing of punching becomes larger.Work as driving cam
20 shapes determine after, mainly the position by axis pin 8 in sliding slot 9 come adjust punching spacing size.
Compared with prior art, there are three important spies compared to existing punch utensil for a kind of card punch of adjustable spacing
Point：
1, time saving and energy saving.The rotary motion of driving mechanism is changed into pumping for mainshaft mechanism, according to physics original
Reason, unidirectional rotary motion can generate larger rotating speed, not have to the action direction for changing power, energy loss is small, per revolution pair
The primary of mainshaft mechanism is answered to pump, so the speed of punching accelerates, and it is laborsaving.
2, compared to the card punch of manual pressure, punch 11 is moved down under the recovery force effect of spring 7, the speed of operation
Degree is exceedingly fast, punched hole the smooth of the edge, neatly.
3, the article that is perforated can realize auto-feed, get equidistant hole, and the need that can be punched according to different articles
It wants, changes punching distance.
