Abstract
The invention provides a kind of improved lathe numerical control device, output in a plurality of ports any one by the multi-way switch of interpolator by user instruction control.Interpolator is selected the switch of closed loop, semiclosed loop simultaneously by user instruction control.The present invention compared with prior art, has the dirigibility in the use, the user only need provide outside necessary close-loop feedback signal and the switch closure that system is relevant, any change needn't be done by system itself, therefore, system after the improvement still can be used for the numerical control transfer matic, plant equipment such as industrial robot except that can be used to control most of lathes.
Description
The present invention relates to a kind of improvement of lathe numerical control device.
Present lathe numerical control device, be subjected to the limitation of its controlling object during design, the quantity of its control coordinate, the control mode of each coordinate etc. has all been fixed, logistics is to have changed when using again, can't be used on other lathe, more can't offer the user as an independent device, the needs that allow the user look oneself determine its use.
The object of the present invention is to provide a kind of device that makes that great dirigibility is arranged in use, the number of control coordinate can be selected and needn't any change be arranged to device a very big scope, and all may command coordinates all can free open loop, a kind of universal numerical control device for machine tool of mode in the closed loop, three kinds of working methods of semiclosed loop.
The multi-way switch that main improvement of the present invention is an interpolator by user instruction control outputs to any one in a plurality of ports.Interpolator is selected the switch of closed loop, semiclosed loop simultaneously by user instruction control.
The present invention also can adopt three output terminals of X, Y, Z of three-dimensional interpolator to connect three multi-way switchs.The multi-way switch of three digit controls can be with three outputs of interpolator by user instruction, be assigned to the output of n road any three the tunnel on.The gating of three multi-way switchs is three the address decode signal controls of X, Y, Z by address decoder, and is corresponding inner at device, is three fixed address.Therefore, when the user need operate some multi-way switchs, reality was sent the port code that will connect to the address of this switching gate signal wire representative exactly and is got final product.Certainly, the user can not directly carry out this device built-in function, can only import with code command, is carried out by device translation back.
Drawing of the present invention is described as follows:
Fig. 1 is an electrical schematic diagram of the present invention.
Fig. 2 is the circuit diagram of eight tunnel outputs of the present invention.
Fig. 3 carries out the judgement and the control flow chart of open loop, closed loop, semiclosed loop for the present invention.
Fig. 4 is the code interpreter process flow diagram of multi-way switch gating of the present invention address.
In conjunction with the accompanying drawings the present invention is described in further detail: as shown in Figure 1, the multi-way switch of three digit controls, user instruction is passed through in three outputs of interpolator, be assigned to n road output any three the tunnel on, for this purpose, must increase the explanation and the executive routine of corresponding user port switching command in the original system software.The gating of three multi-way switchs among the figure is three the address decode signal controls of X, Y, Z by address decoder, and is corresponding to internal system, is three fixed address.Therefore, when the user need operate some multi-way switchs, reality was sent the port code that will connect to the address of this switching gate signal representative exactly and is got final product.For example, user instruction: DJ * * *.Wherein DJ is the statement sign, the back * * * be X output port code in order, Y output port code, Z output port code.When this code was represented with English alphabet, system can select 26 control coordinates altogether.If the multi-way switch gating address of X output terminal is X, the multi-way switch gating address of Y output terminal is Y, and the multi-way switch gating address of Z output terminal is Z, and the output terminal of each multi-way switch is with 0～No. 26 port on the data line.On the output line of n road, be connected to two groups of switches that the n road is respectively arranged, its corresponding each road output is controlled and the switch of selection closed loop, semiclosed loop.The H1 that is connect below the K1 is that a n road is imported or door, or door output meets the set input Z1 of bistable circuit S1.When certain road K1 closed, then in a single day this road had output to make S1 set by K1, H1, because the output Q1 of S1 connects the D7 position of data bus by gate circuit M1, therefore at this time the system data D7 position of reading back will be " 1 ".Because the reset terminal F1 of bistable circuit connects or the output of door H3, so after the S1 set, the pulse of any one input end of H3 all can make S1 reset.The data D7 position that this moment, system read back again then is " 0 ".The circuit that K2, H2, S2, M2 form and above-mentioned identical, the output Q2 of different is S2 meets the D6 of data bus by door M2.Fig. 2 is the hardware physical circuit of one eight road output port, IC1～IC3 among the figure is that 8 of three band data latchings select 1 analog switch 74HC4351, IC4～IC6 is three three input ends three or door 74HC4075, be three road output-parallels that will be connected on X, Y, the Z become an output terminal, and make their mutual electrical isolation.Flow process shown in Figure 3 is to carry out the judgement and the control of open loop, closed loop, semiclosed loop, will the selection of all output terminals is independent of each other.Because although the numeral of judging has only two, feedback signal only uses one the tunnel (many inputs by or door become one the tunnel), but the each output just port of corresponding K connection could trigger bistable switch S, and system judges according to the state of bistable switch whether output puts in place, bistable switch set then is not in place, and system does not just carry out next step interpolation, bistable state resets, and system just carries out next step interpolation.Because bistable circuit only works to a coordinate of current interpolation output, so only can distinguish each coordinate with one the tunnel.This also is the highest a kind of closed-loop control of precision, and departure is less than 1 step.Fig. 4 is the process flow diagram that executive routine is explained in multi-way switch gating address.X is the multi-way switch gating address of X output terminal, and Y is the multi-way switch gating address of Y output terminal, and Z is the multi-way switch gating address of Z output terminal.The output terminal of each multi-way switch is selected with 0～26 on the data line, corresponding to 0～No. 26 port.
The present invention compared with prior art, has the flexibility in the use, the user only need provide necessary closed loop to lock outside signal and the switch closure that system is relevant, any change also needn't be done by system itself, therefore, system after the improvement still can be used for the numerical control transfer matic except can be used to control most of lathes, on other plant equipment such as industrial robot.
