Description
Technical field
The utility model relates to a kind of grinding mechanism of automatic chain grinding machine, the tooth on the grinding saw chain that circulates, 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.The positioning precision of grinding mechanism and rigidity directly decide the stock removal quality of saw chain tooth.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 grinding mechanism of some automatic chain grinding machines, but all there are following shortcomings:
1, grinding mechanism is too complicated, and parts rigidity is not enough;
2, 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;
3, use and inconvenient debugging, requires very high to operator, regulates program very complicated.
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, stable performance, grinding accuracy are high, the grinding mechanism of the simple a kind of automatic chain grinding machine of operation debugging.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
A kind of grinding mechanism of automatic chain grinding machine, it is characterized in that described grinding mechanism comprises cam motor, cam, back shaft, swing arm, access site regulating handle, calibration supporting seat, gear shaft, grinding wheel drive mitor, grinding wheel drive mitor seat, cam motor is connected with cam, access site regulating handle is arranged in swing arm, cam and access site regulating handle head fits, swing arm one end is rotatably installed on back shaft, the swing arm other end is fixedly connected with calibration supporting seat, calibration supporting seat rotates and installs gear shaft, gear shaft is fixedly connected with grinding wheel drive mitor seat.
The utility model is also provided with bearing, and swing arm one end is rotatably installed on back shaft by bearing.
The utility model is also provided with wheel guard, and grinding wheel drive mitor seat is provided with wheel guard.
The utility model is also provided with emery wheel, and grinding wheel drive mitor seat is provided with emery wheel.
The utility model is also provided with for detecting the swing arm induction sense switch whether rollback puts in place, and induction sense switch coordinates with swing arm.
The Principle of Grinding and Cutting of grinding mechanism: cam motor band moving cam moves in a circle, swing arm can ensure according to the different circle diameter positions of cam due to deadweight and the circumference of cam intersects thus transmits power to emery wheel around back shaft rotation, swing arm by parts, and swing arm just achieves grinding feed and the withdrawing of emery wheel around the process that back shaft swings back and forth; Depth of cut is realized by access site regulating handle; On the withdrawing point after utilizing induction sense switch to control a period of motion (feed and withdrawing), emery wheel being in away from saw chain tooth.Mechanism is simple and reasonable; Machinery location by access site regulating handle ensures emery wheel feeding positioning precision and reaches to regulate simple wield object.
The utility model has the features such as reasonable in design, structure is simple, stable performance, grinding accuracy is high, operation debugging is simple.
Accompanying drawing explanation
Fig. 1 is the application structure schematic diagram of the utility model embodiment grinding mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is the application schematic diagram of grinding mechanism.
See accompanying drawing 1, grinding mechanism comprises: cam motor 41, cam 42, back shaft 45, bearing 44, swing arm 43, access site regulating handle 46, calibration supporting seat 52, gear shaft 54, induction sense switch 56, grinding wheel drive mitor 57, grinding wheel drive mitor seat 59, emery wheel 58 and wheel guard 510.Cam motor 41 is connected with cam 42, access site regulating handle 46 is arranged in swing arm 43, swing arm 43 is pushed into appropriate angle to cam 42 by it to join merga pass with access site regulating handle 46 head (Fig. 1 left side), swing arm 43 is minimum angles and grinding duty clockwise, now cam 42 minimum diameter is just to access site regulating handle 46 head, the clockwise maximum angle of swing arm and emery wheel 58 are away from the non-grinding state of saw chain, now cam 42 maximum gauge is just to access site regulating handle 46 head, swing arm 43 one end is rotatably installed on back shaft 45 by bearing 44, swing arm 43 other end is fixedly connected with calibration supporting seat 52, calibration supporting seat 52 rotates gear shaft 54 is installed, gear shaft 54 is arranged on grinding wheel drive mitor seat 59, grinding wheel drive mitor seat 59 is installed emery wheel 58 and wheel guard 510.
The present embodiment also can arrange induction sense switch 56, whether rollback puts (being clockwise to non-grinding state) in place to be used for detecting swing arm 43, on the withdrawing point that emery wheel 58 is in away from saw chain tooth, induction sense switch 56 is connected with control panel, controls saw chain turn to next grinding position by control panel.
Indexing motor 51 in Fig. 1, gear 53, adjustment screw hole 55 are used for the angle of regulating tooth wheel shaft 54, do not belong to grinding mechanism.
The present embodiment main working process is as follows:
Cam motor 41 is with moving cam 42 to move in a circle, swing arm 43 due to deadweight can ensure according to the different circle diameter positions of cam 42 and the circumference of cam 42 intersect thus around the center rotating of back shaft 45, swing arm 43 by each parts transmission power to emery wheel 58, swing arm 43 just achieves grinding feed and the withdrawing of emery wheel 58 around the process that back shaft 45 swings back and forth, and cam 42 often rotates and within one week, namely completes a grinding; Depth of cut is carried out free adjustment by regulating handle 46 and is realized.
