Abstract
The utility model relates to a fan-shaped tooth-wheel and intermittence transmission gear, comprising an input shaft, a transmission shaft, a fixed shaft and an output shaft. The input shaft is assembled with a cam which drives the connecting arm device of the transmission shaft to output the motion of the cam. The transmission shaft is provided with a connecting arm connecting rod gear, which forms a double-rocker gear with a fan-shaped tooth wheel arranged on the fixed shaft. A connecting rod is hinged with the fan-shaped tooth wheel. Thus, the fan-shaped tooth wheel gets the rocking motion from top to bottom. The output shaft is provided with an output wheel, a clutch device and a driven tooth wheel. The clutch device is disengaged or closed, then the fan-shaped tooth wheel is meshed with the driven gear or disengaged with the driven gear, and thus the output wheel outputs the intermittent motion. The utility model provides the higher indexing accuracy and the stability of the intermittent motion.
Description
Technical field:
The relevant a kind of driving mechanism of the utility model, especially relevant a kind of wheeled intermittent drive mechanism of fan tooth that transmits intermittent movement by tooth sector.
Technical background:
Therefore the transmission of many machineries need finally spread out of step motion, yet the power source place generally can not provide step motion, needs by certain transmission device, and the uniform circular motion of power source is converted into final step motion.In the automatic die cutter of sheet platen, promptly need this step circular movement.In the production field of automatic die cutter, producer all adopts the parallel indexing cam mechanism of unit box form to realize the unit motion of main chain wheel at present, and its principle is to utilize one group of parallel graduated cam and equi-index plate to constitute conjugation mechanism, realizes intermittent movement.But the dividing movement precision of this kind of drive depend on the calibration machining accuracy of cam curve and index plate, and the speed of its intermittent movement is subjected to the restriction of cam curve kind.
The model utility content:
The purpose of this utility model is to provide a kind of fan tooth wheeled intermittent drive mechanism, and its rotation by cam control output shaft changes, and uses the clutch of end face groove cam mechanism controls output wheel, realizes reliable intermittent movement.
The purpose of this utility model is achieved in that the wheeled intermittent drive mechanism of fan tooth comprises input shaft, transmission shaft, stationary axle and output shaft, be equipped with cam on the input shaft, can drive the connection arm assembly on the transmission shaft, the motion of cam is spread out of, also has the link arm linkage mechanism on the described transmission shaft, itself and the double rocker mechanism of the common formation of tooth sector that is arranged on the stationary axle, thereby the motion of link arm linkage mechanism is reached tooth sector, described connecting rod and tooth sector hinge joint, thereby the motion that makes tooth sector obtain fluctuating, output shaft is provided with output wheel, engaging and disengaging gear and driven gear, when engaging and disengaging gear disengagement or closure, tooth sector then meshes with driven gear or throws off, thereby output wheel can be exported intermittent movement.
The utility model also has following feature: described clutch one end links to each other so that output wheel stops operating output shaft in the clutch closure with fixing wallboard.
By above-mentioned setting, the utility model has overcome the deficiencies in the prior art, by the wheeled intermittent movement of fan tooth, can make intermittent movement not be subjected to the influence of parallel graduated mechanism cam curve and equi-index plate indexing accuracy, and owing to adopted the pressure locking function of mechanism, the stability of indexing accuracy and intermittent movement is enhanced.
Brief description of drawingsfig:
Fig. 1 is the structural drawing of the wheeled intermittent motion mechanism of the utility model fan tooth.
Fig. 2 be in the wheeled intermittent motion mechanism of the utility model fan tooth the A as shown in fig. 1 on shift fork and the output shaft to view.
Fig. 3 be in the wheeled intermittent motion mechanism of the utility model fan tooth end face groove and in the B as shown in fig. 1 of cam follower to view.
Better embodiment:
See also shown in Figure 1ly, the wheeled intermittent motion mechanism of the utility model fan tooth comprises input shaft I, transmission shaft II, stationary axle III and output shaft IV.Be equipped with the dish type conjugate cam 9 that is formed by two cams on the input shaft I, the Design of cam curves of conjugate cam 9 is impacted transition curve for low, thereby makes operating steadily of entire mechanism.Conjugate cam 9 can promote the cam follower 8 fixed with transmission shaft II, and it can drive the connection arm assembly on the transmission shaft II, and the motion of described conjugate cam 9 is spread out of.Described transmission shaft II goes up also has the link arm linkage mechanism, comprises connecting rod 6 and link arm 7, and connecting rod 6 is connected by axle with link arm 7.Above-mentioned link arm linkage mechanism and the double rocker mechanism of tooth sector 4 common formation that is arranged on the stationary axle III, connecting rod 6 is hinged with tooth sector, thus the motion that makes tooth sector 4 obtain fluctuating.
See also shown in Figure 2ly, output shaft IV is provided with paper-transferring gripper hinge wheel 1 as output wheel, and has engaging and disengaging gear and driven gear 2.Engaging and disengaging gear comprises jaw clutch 5 and shift fork 3, and shift fork 3 can be stirred clutch 5, and engaging and disengaging gear is thrown off or closure.The other end of shift fork 3 drives by the end face groove cam 11 that is arranged on the input shaft I, stirs clutch 5.Clutch 5 is 2 engagements of one end and driven gear when disengaged condition, and its other end links to each other with fixing wall when closed state, thereby make above-mentioned paper-transferring gripper hinge wheel 1 obtain locking, and the grippers defecation has stopped motion reliably.
See also shown in Figure 3ly, have a groove cam ring driven member 10 in the groove of end face groove cam 11, groove cam ring driven member 10 slides in groove, can spur shift fork 3 motions.
Please cooperate and consult Fig. 1, Fig. 2, shown in Figure 3, input shaft I is in arrow direction shown in the Fig. 1 of the drive lower edge of exterior power, then conjugate cam 9 drive connection arm mechanisms are axle center clockwise direction rotation with transmission shaft II, thereby move upward by link arm 7 drivening rods 6, tooth sector 4 upwards shakes.Meanwhile, 11 on end face groove cam drives 3 groups of shift forks to as shown in Figure 2 right-hand member by groove cam ring driven member 10, then clutch 5 is in disengaged condition, and the driven gear 2 of one end can mesh with tooth sector 4, is rotated in a clockwise direction thereby drive paper-transferring gripper hinge wheel 1.
Equally, driving the connection arm mechanisms at conjugate cam 9 is axle center when counterclockwise rotating with transmission shaft II, and link arm 7 drivening rods 6 move downward, and tooth sector 4 also shakes downwards.Meanwhile, 11 on end face groove cam drives 3 groups of shift forks to as shown in Figure 2 left end by groove cam ring driven member 10, then clutch 5 is in closed state, the driven gear 2 of one end can not mesh with tooth sector 4 disengagements, and an end of clutch 5 and fixedly wallboard fix, thereby can make paper-transferring gripper hinge wheel 1 obtain locking when not having the drive of driven gear 2, paper-transferring gripper quits work reliably.
In sum, designer of the present utility model has finished its purpose of design, by the wheeled intermittent movement of fan tooth, make intermittent movement not be subjected to the influence of parallel graduated mechanism cam curve and equi-index plate indexing accuracy, and owing to adopted the pressure locking function of mechanism, the stability of indexing accuracy and intermittent movement is enhanced.
