Detection device and detection method.
Background technology
, it is necessary to machine away the oxide on surface of workpiece when Digit Control Machine Tool carries out seeing that light is processed to workpiece, and Digit Control Machine Tool category
In batch-automated unattended processing, error be present because workpiece is automated in clamping process, by pre-set fixation
Coordinate position dimensioned, easily cause workpiece machining surface uneven, cause undressed, workpieces processing excessively with processing in place
Ratio between workpiece is suitable, and the average qualification rate of workpiece only has 33%.If all selecting dimensioned, though oxide layer can
Realize and all see that light is processed, but the overall dimensions of workpiece can be affected, and particularly with magnetic material, the performance of product can be made big
Give a discount.Existing solution is just equipped with tool setting gauge, determines work surface location with tool setting gauge, realizes processing, and makes
With tool setting gauge, the problem of new is brought again, if workpiece surface is uneven, tool setting gauge can only perceive peak or certain point, to processing
Size brings error again, has been returned to 33% passing rate of processing, and using tool setting gauge from determination position to processing, lathe needs
Tool setting gauge and process tool position are changed, extends process time, for seeing that light workpieces processing is fatal again, in addition to knife
Instrument is with high costs, not yet popularizes at present, therefore a kind of economic and reliable extremely to be supplied and accurately realizes that workpiece surface oxide is shown in
The detection device of light processing, to lift the qualification rate of product.
The content of the invention
Present invention solves the technical problem that：There is provided it is a kind of for Digit Control Machine Tool precisely see light workpieces processing detection device and

The accurate of unattended automation sees that light is processed when existing cutter is to workpiece surface oxidation processes, and the qualification rate of product is reachable
99.8%, and the control loop realizes economic and reliable, it is applied widely, there is larger application value.
Brief description of the drawings
Fig. 1 is structural principle block diagram of the present invention；
Fig. 2 is the machining sketch chart of the present invention.
Embodiment
A kind of embodiment of 1, the 2 description present invention below in conjunction with the accompanying drawings.
The detection device of light workpieces processing is precisely seen for Digit Control Machine Tool, there is the cutter 2 with Digit Control Machine Tool to pass through wire
The detection control loop of connection, the detection control loop include electric signal carrying out the Dolby circuit 3 of noise reduction process, by noise reduction
Signal amplification circuit 4, the signal for being changed electric signal that electric signal afterwards carries out the undistorted enhanced processing of signal change electricity
Road 5, the signal criterion 6 being contrasted with the signal after conversion, the comparison that the signal after conversion is compared with reference signal
Circuit 7, the drive circuit 8, Yi Jiyu that the output signal after comparison is realized on or off through drive circuit 8 to control loop
The output circuit 9 that drive circuit 8 connects.
Specifically, the input of the Dolby circuit 3 is connected with cutter 2 by wire, to obtain current signal, noise reduction
The output end of circuit 3 is connected with the input of signal amplification circuit 4, output end and the signaling conversion circuit 5 of signal amplification circuit 4
Input connection the signal after amplification grabbed changed, the input of the output end connection comparison circuit 7 of signaling conversion circuit 5
End, input of the signal criterion 6 also with comparison circuit 7 are connected, are compared in comparison circuit 7, the output end of comparison circuit 7
Connect the input of drive circuit 8, the output circuit 9 of the output end connection detection control loop of drive circuit 8, the output electricity
Road 9 is connected by wire with the servo-control system for the cutter 2 for controlling Digit Control Machine Tool.
When comparison circuit 7 exports high level, drive circuit 8 exports Continuity signal；The comparison circuit 7 exports low level
When, drive circuit 8 exports cut-off signals.When output circuit 9 has signal output, the SERVO CONTROL system of the cutter 2 of Digit Control Machine Tool
System stops the processing to workpiece 1；When the no signal of output circuit 9 exports, the servo-control system of the cutter 2 of Digit Control Machine Tool continues
Processing to workpiece 1.
Operation principle of the present invention is, as shown in figure 1, lathe work in-process, cutter 2 is processed to the surface of workpiece 1, workpiece
1 A areas are metal oxide area, and B areas are metal body area, due to poorly conductive of the metal oxide compared with metal body, therefore,
When cutter 2 contact workpiece 1 A areas when, compared with B areas have a small amount of electric current by wire input Dolby circuit, by electric signal successively
Carry out noise reduction process, enhanced processing, comparison circuit 7 inputted after conversion process, in comparison circuit 7 with the setting of signal criterion 6
Value compares, and the signal input value of comparison circuit 7 is less than the baseline signal value of signal criterion 6, and comparison circuit 7 exports low level, low
Level makes drive circuit 8 export cut-off signals, the output of the no signal of output circuit 9, therefore the SERVO CONTROL of the cutter 2 of Digit Control Machine Tool
System continues to be processed the surface of workpiece 1.On the contrary, when cutter 2 is processed to a certain extent into the metal body B of workpiece 1
Qu Hou, there are a large amount of electric current input Dolby circuits 3 compared with A areas, similarly, noise reduction process, enhanced processing, conversion are carried out successively to electric signal
Comparison circuit 7 is inputted after processing, the signal of input comparison circuit 7 is far above signal criterion 6, and comparison circuit 7 exports high level, high
Level makes drive circuit 8 export Continuity signal, and output circuit 9 has signal output, therefore the SERVO CONTROL of the cutter 2 of Digit Control Machine Tool
System stops feed, it was demonstrated that the oxide on surface of workpiece 1 is processed to be finished, it is ensured that cutter 2 just breaks through the oxidation on the surface of workpiece 1
Layer, precisely complete unattended automation and see that light is processed.
As shown in Fig. 2 during machine tooling, tool rest 11 along machine Z-axis direction close to workpiece 1, when cutter 2 touches workpiece 1
Afterwards, the surface oxide layer of the turner 1 of cutter 2, the no signal of detection device 10, tool rest 11 continue close to workpiece 1, when cutter 2 is complete
After the full surface oxide layer for breaking through workpiece 1, detection device 10 judges that the oxide layer of workpiece 1 has been dashed forward by detecting control loop
It is broken, the digital control system of headstock 13 is outputed signal to, machine chuck 12 connects headstock 13, the clamping workpiece of machine chuck 12
1, tool rest 11 moves stopping along machine Z-axis, and tool rest 11 is let pass along lathe X-axis again to advance, and whole cars fall the surface oxidation of workpiece 1
Layer.
Compared with prior art, the present invention solves accurate in the unattended automation processing of workpiece surface oxidation processes
See that light is processed, break through workpiece surface oxide layer contact detection control loop by adding cutter in numerically controlled lathe, by product plus
Work qualification rate brings up to 99.8%, and this detection device is extended in the detection processing of other machining apparatus, has larger answer
With value.
Above-described embodiment, simply presently preferred embodiments of the present invention, is not used for limiting the scope of the present invention, therefore all with this
The equivalence changes that content described in invention claim is done, it all should be included within scope of the invention as claimed.
