Driven gear is engaged with tooth, slip teeth, the driven gear is arranged on the driving crank axle of the second crank and rocker mechanism.
The U-type groove of radial direction is provided with the fan-shaped centering block, the pitman shaft of first crank and rocker mechanism is installed
Fixed in U-type groove, and through bolted splice.
First crank and rocker mechanism include the crank with crank axle, one end of the crank articulated linkage, connecting rod it is another
The pitman shaft is fixedly installed in one end；Second crank and rocker mechanism includes the driving crank with driving crank axle, and this is driven
Crank is hinged follower link, and the follower link is hinged one end of swing rod, and the middle part of the swing rod sets the swing rod axle for being fixed on frame,
The other end of the swing rod sets swing rod drive shaft.
The arc length of the slip teeth is less than the arc length of sliding guide groove, and its arc length difference is determined according to interval amplitude size.
The U-type groove is arranged on the symmetrical centre line position of fan-shaped centering block.
The segment angle of the fan-shaped centering block is between 90 ° -180 °.
The present invention promotes the slip teeth reciprocally swinging on fan-shaped centering block by the first crank and rocker mechanism, then by being put with sector
The driven gear of block engagement connects the second crank and rocker mechanism, the swing rod of the second crank and rocker mechanism is realized upper and lower past physical pendulum
It is dynamic.
During work, pitman shaft of the present invention can up and down be adjusted according to amplitude of fluctuation size requirement in U-type groove, be realized different
Occasion demand.Slip teeth reciprocal beat of batch (-type) in sliding guide groove, it is possible to achieve swing rod drive shaft is irregular to be swung, and swing rod drives
The amplitude of oscillation of moving axis can change the number of teeth of driven gear to be adjusted according to different demands, therefore the course of work is easy to adjust,
Regulative mode is various.

Embodiment
As Figure 1-Figure 4, a kind of reciprocal embodiment of swing-bar mechanism one of clearance-type of the invention is main by crank axle 1, crank
2nd, connecting rod 3, first baffle 4, driving crank axle 5, driving crank 6, follower link 7, driven gear 8, U-type groove 9, pitman shaft 10,
Slip teeth 11, swing rod 12, swing rod axle 13, sliding guide groove 14, second baffle 15, swing rod drive shaft 16, fan-shaped centering block 17, fan-shaped swing-block shaft
18 grades are constituted.Wherein：The driving drivening rod 3 of crank 2 of crank axle 1 moves reciprocatingly, and connecting rod 3 and fan-shaped centering block 17 pass through pitman shaft
10 are hinged and connected, and pitman shaft 10 is arranged in the U-type groove 9 on fan-shaped centering block 17, and is fixed using bolt, can be with timely adjustment not
Same position.The fan-shaped top of centering block 17, which is designed with sliding guide groove 14, sliding guide groove 14, is arranged with slip teeth 11, and the sliding two ends of guide groove 14 have first
