The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to shown in Fig. 1 to Fig. 3, the invention discloses a kind of cutting mechanism that floats, unsteady cutting mechanism comprises cutter head constant moment press mechanism, cutter head constant moment press mechanism comprises the first installing plate 10 and is arranged on the first servomotor 20 on the first installing plate 10 right flanks, the output shaft of the first servomotor 20 is through the first installing plate 10, the first servomotor 20 is positioned on the output shaft of the first installing plate 10 left surfaces installs gear 30, gear 30 connects a tooth bar 40, tooth bar 40 is arranged on tooth bar installing plate 50, work hour rack installing plate 50 moves with tooth bar, the below of tooth bar installing plate 50 connects a plate 60.
The present invention is unsteady, and cutting mechanism also comprises cutter head rotating mechanism, and cutter head rotating mechanism comprises that the second installing plate 70, the second installing plates 70 are reversed F-typed, and it comprises vertical installation end 71, the first horizontal installation end 72 and the second horizontal installation end 73; Vertically the upper side of installation end 71 is connected with connecting plate 60; The below of the first horizontal installation end 72 is provided with cutter head cutter sweep 80, the top of the first horizontal installation end 72 is provided with shaft coupling 90, the top of the second horizontal installation end 73 is provided with the second servomotor 100, and cutter head cutter sweep 80 is connected by shaft coupling 90 with the second servomotor 100.
The top of the first installing plate 10 is provided with the 3rd installing plate 110, on the first installing plate 10 and the 3rd installing plate 110, be equipped with erection column 130, the two ends of elastic mechanism 120 are connected with the erection column 130 on the first installing plate 10 and the 3rd installing plate 110 respectively, when cutter head rotating mechanism is in zero-bit, the gravity of cutter head rotating mechanism is by elastic mechanism balance, elastic mechanism 120 of the present invention is selected spring, and according to actual needs, it also can select other elastic mechanism.
Cutter head cutter sweep 80 of the present invention is comprised of cutter head fixed mechanism 81 and the cutter head that is arranged on cutter head fixed mechanism 82 belows, and cutter head fixed mechanism 81 is connected with shaft coupling 90 by bearing (not marking in figure).

The present invention 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, with low rubbing cylinder, control and exert oneself; 2, with servomotor, control and exert oneself.
With regard to these two kinds of control modes of exerting oneself, do a contrast 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 when 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 when load current changes, exert oneself (torsion) does not have the physical impedance problem of cylinder.
With one group of form, facing to two kinds of control modes of exerting oneself, do a detailed comparison below:
Comprehensive above contrast, the float mode of exerting oneself of cutting mechanism of the present invention is selected the servomotor mode of exerting oneself.
Operation principle of the present invention 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, when 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 guarantee that cutter head is consistent to the depth of cut of workpiece; While needing to carry out Y-direction cutting after directions X cuts to assigned address, 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 basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
