System adopts two MPC08 motion control cards can control at most eight kinematic axis.X, Y, Z tri-axle by No. 1 card control, U, W axle is by No. 2 card control, and all axles can realize any three-shaft linkage.Due to the larger employing dual-side driving method of Y-axis crossbeam span.Dual-side driving method: a road pulse is become two identical pulses with direction signal through one piece of bilateral driving pulse distribution plate and exports by card pulse, controls Y-axis two servomotors respectively.Hand arteries and veins adopts RS232 interface, and X, Y, Z, U, V, W axle shelves, multiplying power gear and encoder rotating information on hand arteries and veins box are sent to PC by serial ports by design specialized circuit.PC program process serial ports interrupts, and sends instruction perform corresponding sports according to serial ports.
Low in order to solve numerical control drilling machine of the prior art manual tool setting efficiency, low precision, operates extremely inconvenient technical problem, and the boring method that the application provides a kind of Double end digital control to bore said method comprising the steps of:
Step S101, adopts unit head 1 setting circle disc type work three point coordinates, calculates the central coordinate of circle of disc-like workpiece according to three point coordinates.
Particularly, seeking border can be adopted to find any three point coordinates (x of the edge of work
1, y
1), (x
2, y
2), (x
3, y
3), or lathe is after Aligning control, adopts active force 1 positioning disc workpiece three point coordinates.Locate successfully and press the input of centering three point coordinates at MDI interface, system automatic Memory three point coordinates.If input point coordinate identical systems can alarm.According to the center of circle three point coordinates (x
1, y
1), (x
2, y
2), (x
3, y
3) calculate workpiece central coordinate of circle (x
0, y
0) computing formula as follows:
Disc-like workpiece is circular tube sheet, can select arbitrarily for 3, if be deflection plate, then needs to select 3 points on arc surface.
Step S102, according to described disc-like workpiece central coordinate of circle (x
0, y
0), described disc-like workpiece is carried out to the layout of circular hole.
Step S103, according to the layout of described circular hole, disc-like workpiece carries out the processing of described circular hole.
The boring method that above-mentioned Double end digital control bores, by adopting active force 1 setting circle disc type work three point coordinates, calculates the central coordinate of circle of disc-like workpiece, according to described disc-like workpiece central coordinate of circle (x according to three point coordinates
0, y
0), described disc-like workpiece is carried out to the layout of circular hole, according to described disc-like workpiece central coordinate of circle (x
0, y
0), described disc-like workpiece is carried out to the layout of circular hole, the easy to operate efficiency of the method is high, and centering precision is high, solves numerical control drilling machine of the prior art manual tool setting efficiency low, low precision, operates extremely inconvenient technical problem.
In order to avoid disc-like workpiece puts injustice on the table, and occur the phenomenon that some circular hole does not bore, described method also comprises:
Step S104, when receiving a time-out control signal, described unit head suspends the processing to described circular hole.In processing arbitrarily, pressing F3 pause button can suspend processing.
Step S105, after adjusting the feeding depth of described unit head 1Z axle and described unit head 2W axle, continues to process the carrying out of described circular hole.
Large format workpiece point socket drill adds man-hour, and usual drilling depth is more shallow, is generally 3-6mm.After large-scale workpiece is well placed on the table, due to the uneven reason of finished surface, be generally difficult to accomplish that machined surface and workbench are completely parallel.Because workpiece breadth is large, weight is large, and artificial smoothing difficulty is large, has no idea to smooth completely.Machined surface and work top have certain inclination (angle is generally less than 0.02 degree), if diameter of work is 3m, the deviation on such height may have 0.5-1mm.If according to the center of circle tool setting Z axis height during tool setting, so add the Kong Huidian likely had man-hour dark, some Kong Huidian are shallow, the hole point even had less than.By suspending the process of described disc-like workpiece carrying out described circular hole, after adjusting the feeding depth of described unit head 1Z axle and described unit head 2W axle again, disc-like workpiece can be avoided to put injustice on the table, and occur the phenomenon that some circular hole does not bore.
After step s 104, null speed and the feed speed of described unit head can also be adjusted, as shown in Figure 7.
In addition, after step s 104, receive the designation hole information of processing at the beginning, according to described designation hole information, the circular hole of described designation hole number is processed, as shown in Figure 6.That is, can process from any designation hole number, can solve sometimes because have some holes not get under the emergency case such as Drill Crack like this; Or because workpiece is uneven in a socket drill, cause some holes not put; Or need the problem of processing from designation hole number in breakpoint processing, in order to avoid will again from the beginning process, lose time.。
In process, the circular hole processed described in control and unprocessed circular hole show in a different manner, as shown in Figure 7, so just to drilling power head track and drilling track tracking display in processing, can facilitate direct vision lathe running status.
Particularly, process motion graphics tracking display: automatically processing start after except setting up a special processing thread, also has a user-interface thread, it is corresponding that user-interface thread is mainly used to process user message, and set up a timer, periodic refreshing conditions of machine tool, and simultaneous display bit course, bore position.
Figure tracking concrete grammar is as follows: obtain unit head positional information, positional information is converted to the pixel information of figure, carries out virtual borderlines.Paintbrush XOR pattern is first adopted to wipe former drill bit figure when drawing bit location, then drill bit is redrawn at reposition, meanwhile, according to processing hole count information, by machining hole white filling in figure, such user just can be easy to current state and the bit location information of observing processing.
Particularly, as shown in Figure 8, for adopting the flow chart of the processing thread of the boring method in Fig. 1.Digital control system specific function realizes adopting multithreading, automatic factory interface is pressed and is started to process rear establishment one processing thread, the flow process of processing thread is as follows: after opening the G code after compiling, read the effective G code of a line, if line number is less than NUm, then undo, directly reads next line.If line number is greater than or equal to NUm, then down performing a programme.If press pause button in processing, thread directly can exit and preserve current processing line number Num and Working position information, press continue processing button restart thread, but Num capable before G code can not be performed.Be exactly any time-out in the processing realized like this and continuation.Have individual isfirst flag bit when performing G code, it is true that thread starts preposition isfirst, as truly G code initial point position information is determined by digital control system memory point, if be that vacation so performs according to G code raw information.Can ensure like this to continue after performing certain motion Machining Instruction suspends, movement locus can not be muddled things up.
Percentage regulation is suspended: the compensation depth parameter (zcomp and wcomp) arranging Z axis and W axle, adjusts Z, W position after time-out, the information of system automatic Memory zcmp and wcomp in processing.Adjust 0.1mm, so zcomp=zcomp+0.1 under Z-axis direction after such as suspending, encountering the feeding of Z, W axle when performing G code is all complete separately, does not participate in moving interpolation.The G code motion value of Z axis and W axle is zcode and wcode, so actual feeding size zpos=zcode+zcomp; Wpos=wcode+wcomp; So convenient realization suspends adjustment feeding depth problem in processing.Depth compensation value continues up to process finishing.
Meaning designation hole number can be taken office after time-out restart: to pressing any hole button after time-out, after setting hole n, program calculates No. NUm, the program in the n-th hole automatically, creates a new processing thread, first thread performs the program of griffing, and prevents from hitting cutter in movement.After improving, other operations are with identical above.
In actual process, single head processing and the automatic transformation function of double end machining code, behind location, the disc-like workpiece center of circle, can adopt single drill bit to process, and also can adopt two drill bit processing.Digital control system has built-in algorithm, can according to minimum range, drill bit between home position, two drill bits separately moving range automatically calculate optimum double end movement locus.Single head processing and double end are processed a key and are switched.
In addition, system is owing to adopting PC+motion control card structure, and software merit rating is flexible.System is also with built-in integrated CAM function.Directly can read AutoCAD and design drillhole pattern.Directly G code is exported after setting processing technology.The way of output has annular array, line scanning two kinds of modes.Can also conveniently set the machined parameters such as process velocity, drilling depth.Double end digital control bores needs digital control system to process by single head, again can double end processing.Because double-control system G code is all the machining locus set up for model with single drill bit usually.Known workpiece centre is needed again to plan the two drill bit machining path of calculating in machine coordinates point confidence and according to the physical location information of two drill bits if realize two drill bit processing.Existing drilling machine system does not possess on-line conversion function, all needs special-purpose software G code to be reinterpreted rear generation double end machining code, then passes to digital control system.Most common form is that a number of units Ore-controlling Role+special purpose computer carries out CAM conversion, and transcode passes to digital control system again by serial ports or network.This mode of operation is complicated, requires higher to operative employee.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
