Description
Technical field
The utility model relates to a kind of tooth pushing mechanism of automatic chain grinding machine, promotes the tooth on saw chain for circulating, and belongs to a composition mechanism of chain grinding machine.
Background technology
Saw chain is the cutting part on chain saw, about its cutting edge point, blade is present in the middle of same saw chain simultaneously, saw chain is the cutter for cutting object, what can become after Long-Time Service is not sharp, cause cutting resistance to become even cannot cut greatly, thus need to carry out grinding to saw chain tooth, make it can continue to meet need of work.Tooth pushing plays an important role in whole grinding process, and whether the stock removal that the positioning precision of tooth pushing and rigidity directly decide saw chain tooth can meet grinding demand.In prior art, usually adopting manual tooth pushing grinding method, there is the problems such as positioning precision is low, inefficiency, labour intensity are large in this mode.
Now commercially also there is the tooth pushing mechanism of some automatic chain grinding machines, but all there are following shortcomings:
1, Song Lian tooth pushing mechanism is too complicated, and transmission process is too many through parts, increases tooth pushing load and accumulative intermittent error.
2, tooth pushing is that the principle in push broach face is unreasonable, cannot ensure that the length of each tooth after grinding reaches consistent, and the long inconsistent meeting of tooth causes the laod unbalance of left and right in chain saw real work working angles, has a strong impact on cutting effect.
3, there is assembling cumulative errors and plastic deformation situation in a lot of parts (particularly belt transmission), in feeding process stability and positioning precision very poor, cannot process requirements be met.
4, use and inconvenient debugging, requires very high to operator, regulates program very complicated.
5, tooth pushing process does not detect the device of left and right knife-edge automatically, cannot meet the grinding requirement of left and right knife-edge No-L aw Order saw chain.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provide that a kind of reasonable in design, structure is simple, tooth pushing mechanism that stable performance, the grinding that meets various profile of tooth arrangement saw chain required, operated the simple chain grinding machine automatically of debugging.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
A kind of tooth pushing mechanism of automatic chain grinding machine, comprise motor, driving cog, fork, fork axle, screw pin, tooth pushing pawl, limited block, grinding position regulating handle, tooth pushing position control lever and housing, motor, fork axle, grinding position regulating handle, tooth pushing position control lever is installed on housing, motor shaft is provided with driving cog, driving cog engages with the sector of fork, fork is rotatably installed on fork axle, tooth pushing pawl is rotatably installed on fork by screw pin, fork is fixedly connected with limited block, grinding position regulating handle, tooth pushing position control lever is all corresponding with limited block.
Tooth pushing pawl described in the utility model is provided with and stops inclined-plane, tooth pushing circular arc and screw pin installing hole, and screw pin is sleeved on screw pin installing hole.
Stop inclined-plane described in the utility model is cambered surface or the inclined-plane of indent, is conducive to tooth pushing pawl on the one hand and slides on saw chain tooth, is not easy wearing and tearing, also alleviates component on the other hand and reduces cost.
Fork described in the utility model is arranged on fork axle by fork installing hole.
The utility model also can arrange left and right profile of tooth induction sense switch, and left and right profile of tooth induction sense switch can be arranged on housing, just to that saw chain tooth of tooth pushing position.
The principle of the utility model tooth pushing mechanism kinematic and control thereof: direct current generator rotates the torsion produced and passes to swing arm by gear, and swing arm moves in a circle around axle, swing arm is passed to thrust by screw pin and pawls; Pawl to contact with the saw chain back of tooth and promote saw chain tooth to grinding position, two regulating handles by the tooth pitch of saw chain regulate tooth pushing to move respectively rise, stop bit puts; The interaction of the torsion that tooth pushing exports to grinding position rear motor always and machinery location thus produce enough holding torques, makes positioning and rigid strengthen; The method of the tooth pushing back of the body ensure that each tooth length after grinding is consistent, thus improves the use stationarity of saw chain and do corresponding indexing action service life.Mechanism is simple and reasonable; Machinery location by regulating handle ensures tooth pushing positioning precision.
The utility model has the features such as reasonable in design, structure is simple, stable performance, adaptability is good, operation debugging is simple.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing:
See Fig. 1 ~ Fig. 4, the present embodiment tooth pushing mechanism comprises: motor 20, driving cog 21, fork 22, fork axle 23, screw pin 24, tooth pushing pawl 25, limited block 26, grinding position regulating handle 27, tooth pushing position control lever 28 and be used for install housing.Motor 20, fork axle 23, grinding position regulating handle 27, tooth pushing position control lever 28 is installed on housing, motor 20 axle is provided with driving cog 21, driving cog 21 engages with the sector 221 of fork 22, fork 22 is rotatably installed on fork axle 23 by fork installing hole 222, tooth pushing pawl 25 is arranged on fork 22 by tooth pushing pawl installing hole 223 and screw pin 24, fork 22 is connected with fork axle 23 with limited block 26 is fixing, grinding position regulating handle 27, tooth pushing position control lever 28 is all corresponding with limited block 26, limited block 26(bottom when wherein grinding position regulating handle 27 head (on the right of Fig. 1) and fork 22 drive tooth pushing pawl 25 to move to grinding position) corresponding (see Fig. 2), now tooth pushing pawl 25 is positioned at after certain saw chain tooth 29 needing grinding just, limited block 26(top when tooth pushing position control lever 28 and fork 22 drive tooth pushing pawl 25 to move to tooth pushing position) corresponding, now tooth pushing pawl 25 is positioned at after certain saw chain tooth 29 needing to promote just.
It is (not shown on figure that the present embodiment also can arrange left and right profile of tooth induction sense switch, distance detection switch can be adopted), left and right profile of tooth induction sense switch is arranged on housing just to that saw chain tooth 29 of tooth pushing position, judge left tooth or right tooth according to the result detected, thus adjustment indexing motor does corresponding dividing movement accordingly.
As Fig. 2, motor 20 rotates forward, by gear 21, torsion is passed to fork 22, fork 22 moves in a circle around the center of fork axle 23, fork 22 drives tooth pushing pawl 25 to move (rotating clockwise) by screw pin 24, in tooth pushing process, tooth pushing pawl 25 enters into saw chain tooth 29 groove and saw chain tooth 29 rear-face contact below under gravity, thus promotion saw chain tooth 29 moves toward grinding position, the accurate location of grinding position adjusts by grinding position regulating handle 27; Change motor 20 to turn to, thus tooth pushing pawl 25 can be realized toward moving (rotating counterclockwise) relative to the opposite direction of grinding position, under the effect of tooth pushing pawl 25 winding block face 253, when running into saw chain tooth 29, tooth pushing pawl 25 up lifts and walks around saw chain tooth 29, rotating counterclockwise distance tooth pushing position control lever 28 regulates spacing according to the tooth pitch of saw chain, after arriving restraining position, tooth pushing pawl 25 enters in the groove of saw chain tooth 29 back of the body under the effect of deadweight, thus can realize reciprocal tooth pushing motion.
As Fig. 3, tooth pushing pawl 25 is provided with and stops inclined-plane 253, tooth pushing circular arc 251, screw pin installing hole 522.
As Fig. 4, fork 22 is provided with sector 221, fork axle installing hole 222, tooth pushing pawl installing hole 223.
