Detailed description of the invention
The preferred embodiment of the drilling machine of two-part displacement of the present invention, as shown in Fig. 2 to 5, comprises:
Two first guide rails 20, parallelly to be oppositely arranged, and respectively this first guide rail 20 has two ends, respectively the closure at these the first guide rail 20 two ends is defined as first direction D1, vertical first direction D1 is defined as second direction D2, and this each first guide rail 20 of the present embodiment is linear slide rail;
Multiple optical ruler 30, is arranged at respectively on this first guide rail 20 along first direction D1;
One equipment platform 40, being slidedly arranged on also can along first direction D1 displacement on this first guide rail 20, and this equipment platform 40 is arranged two the second relative guide rails 41, respectively this second guide rail 41 is arranged along second direction D2, and respectively this second guide rail 41 arranges multiple optical ruler 30 along second direction D2, this equipment platform 40 has a control unit 42, this control unit 42 is provided with setting the equipment platform shift length of this equipment platform 40 along this first direction D1 displacement, and this control unit 42 is electrically connected a power source 43 and each this optical ruler 30, this power source 43 of the present embodiment is servo motor, and this control unit 42 comprises outline controlling mechanism 421 and a fine compensation controlling mechanism 422, as shown in Figure 4, this power source 43 controls start by this outline controlling mechanism 421 and this fine compensation controlling mechanism 422, this power source 43 is by this outline controlling mechanism 421 command displacement first shift length, this first shift length is 99.1 ~ 99.9% of this equipment platform shift length, then this power source 43 controls this equipment platform 40 displacement second shift length by this fine compensation controlling mechanism 422 again, this second shift length is calculated according to this first shift length and this equipment platform shift length by this fine compensation controlling mechanism 422, this second shift length be less than or equal to this equipment platform shift length 0.01 ~ 0.09% distance, and the summation of this first shift length and this second shift length is this equipment platform shift length, as shown in Figure 5.
At least one units 50, on two these second guide rails 41 being arranged at this equipment platform 40 slippingly and can along second direction D2 displacement, the present embodiment arranges two units 50.
One positioner 60, connect this equipment platform 40 and relatively this first guide rail 20 is arranged, and this positioner 60 connects this control unit 42, this control unit 42 can control this positioner 60 clamping position in this first guide rail 20, uses the position controlling this equipment platform 40 and be positioned on this first guide rail 20.
It is more than the structural relation of the drilling machine of two-part displacement of the present invention, this units 50 can in the second guide rail 41 top offset of this equipment platform 40, and again can together with this equipment platform 40 in this first guide rail 20 top offset, and this control unit 42 of the present invention comprises this outline controlling mechanism 421 and fine compensation controlling mechanism 422, during running, first be through this outline controlling mechanism 421 and control this this first shift length of power source 43 displacement, this first shift length is 99.1 ~ 99.9% of this equipment platform 40 shift length, that is, this outline controlling mechanism 421 is the displacements controlling this equipment platform 40 preliminary outline, when after this this first shift length of equipment platform 40 displacement, now this equipment platform 40 does not meet required shift length completely because of the displacement of outline, and also may produce the margin of error of skew because of displacement in the both sides of now this equipment platform 40.
Now, this control unit 42 controls the position that this optical ruler 30 senses this equipment platform 40, that is, this optical ruler 30 senses the exact position of this first shift length, and the signal of this first shift length is provided give this fine compensation controlling mechanism 422, then this precise hard_drawn tuhes compensatory control mechanism 422 calculates the second shift length, this second shift length is the difference of this equipment platform shift length and this first shift length, and this precise hard_drawn tuhes compensation mechanism 422 drives this equipment platform position 40 to move the second shift length according to this power source 43 of the output control calculated; This equipment platform 40 is located by this positioner 60 again after being moved to set equipment platform shift length.
By this, the displacement that this power source 43 produces two-part is controlled through this outline controlling mechanism 421 and this fine compensation controlling mechanism 422, this outline controlling mechanism 421 controls the preliminary displacement of power source 43 driving arrangement platform 40, make not need in the process of this equipment platform 40 displacement first shift length to continue to carry out accurate sensing or calculating, but after this equipment platform 40 outline displacement, this optical ruler 30 is coordinated to sense the exact position of the first shift length passively, numerical value after sensing then becomes the control foundation of fine compensation controlling mechanism 422, the once passive sensing of this optical ruler 30 is only needed in molar behavior process, and once calculating of this fine compensation controlling mechanism 422 can complete accurate drived control, need sensing do not continued on the way in the process of displacement and calculate, significantly can improve the operation time of this control unit 40, and displacement accuracy also can be precisely controlled, simultaneously, because control unit 40 of the present invention only needs to carry out computing once and sensing, therefore the outfit level requirements of this control unit 40 is not high, outfit grade and the cost of this control unit 40 can be reduced, also reduce integral device cost simultaneously, and improve overall surcharge.
