The utility model only needs two servomotors in when work, and it is simple in structure, operate steadily, cost is low, control is reliable.
In research cutter head constant moment press mechanism driving process, there are two selections: 1, control and exert oneself with low rubbing cylinder; 2, control and exert oneself with servomotor.
Do a contrast with regard to these two kinds of control modes of exerting oneself below:
Cylinder is to adopt exerting oneself of carrying out of compressed air, so it uses pressure regulator valve to carry out the adjusting of pressure; That is to say, cylinder carries out the control of pressure by the pressure control of pressure regulator valve and the guiding of air pipe arrangement.
But pressure control and susceptibility all can the physical arrangement factor in the time exerting oneself change because of cylinder or air bag.
The servomotor mode of exerting oneself, is that the control of torsion is carried out in the variation of working load electric current, that is to say that the adjusting control of in the time that load current changes, exert oneself (torsion) does not have the physical impedance problem of cylinder.
Do a detailed comparison with one group of form facing to two kinds of control modes of exerting oneself below:
Comprehensive above contrast, the float mode of exerting oneself of cutting mechanism of the utility model is selected the servomotor mode of exerting oneself.
Operation principle of the present utility model is as follows:
This mechanism is first transferred to zero-bit when mounted, the weight of cutter head rotating mechanism is carried out balance by spring mechanism 120 just, in the time that unsteady cutting mechanism starts cut work piece cut, the first servomotor 20 on cutter head constant moment press mechanism starts, the output shaft driven gear 30 of the first servomotor 20 rotates, and gear 30 drives tooth bar 40 to move, and tooth bar 40 is with carry-over bar installing plate 50 to move, tooth bar installing plate 50 drives connecting plate 60 to move, and connecting plate 60 drives the second installing plate 70 to move; The second installing plate 70 on cutter head rotating mechanism declines along line slideway 140, and make cutter head depth of cut arrive assigned address, at this moment set the output torque of the first servomotor, make it keep constant output torque, then start along directions X cutting, when encountering the place of cut surface of the work injustice, because the first servomotor output torque is constant, so whole cutter head rotating mechanism also can follow surface of the work and automatically adjust, thereby ensure that cutter head is consistent to the depth of cut of workpiece; Need to carry out Y-direction cutting after directions X cuts to assigned address time, cutter head constant moment press mechanism drives cutter head rotating mechanism to rise, then the first servomotor control cutter head cutter sweep 80 half-twists, then cutter head constant moment press mechanism presses down cutter head rotating mechanism to put in place according to the moment of torsion setting originally, then start Y-direction cutting, and so forth.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
