The invention discloses a device for determining the output of a control signal by utilizing an absolute position. The device comprises a transmission component, an absolute value encoder and a PLC (Programmable Logic Controller), wherein the transmission component comprises a drive part and a driven part, and the drive piece is fixedly arranged on a workbench of processing equipment; the driven part is fixedly arranged on a shaft core of the absolute value encoder to determine the absolute position of the workbench according to the movement of the driven part and output an absolute position signal; and the PLC is used for receiving the absolute position signal transmitted by the absolute value encoder and outputting the control signal to the processing equipment according to the absolute position signal. The device has the benefits that the transmitted absolute position signal is determined through the engagement of a rack and a gear, the signal transmission is reliable, stop iron and a combined switch are triggered without the workbench to transmit the signal, the adverse consequence caused by inaccurate triggering or no triggering and other failures is avoided, the signal transmission is timely and accurate, and the processing precision of products is ensured.
Description
Technical field
The present invention relates to field of machining, particularly a kind of device that utilizes absolute position to determine control signal output.
Background technology
Boring, milling, bore and wait the reciprocation type of processing to control special plane and transfer matic, be subject to feed shaft power, spindle power, cutter, chip removal, the factor impacts such as processing technology, need to be to running statuses different in process (as F.F., slow-motion, work is entered) carry out the time, the controls such as position, in prior art mostly in the following way: one or more stacked switches are installed on workbench, and with the corresponding position of each running status, buting iron is set on slide rail, when workbench slides into some buting iron (as F.F.) along slide rail, corresponding switch is closed and this signal is transferred to PLC controller, PLC controller output control signal, workbench is carried out corresponding running status (being F.F. operation).But, because the sensitivity of stacked switch is not high, poor reliability, in use procedure or after long-term use, because tired, metal rusting bonding, oxidation loose contact or buting iron deformation failure or machinery inertial etc. cause control signal output error compared with making Product Precision poor greatly, even occur that switching signal input is chaotic or without input, cause that control is out of control, finally cause the accidents such as equipment collision, cracking of cutter, product rejection.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Summary of the invention
The object of the present invention is to provide a kind of device that utilizes absolute position to determine signal output, thereby the cooperation that overcomes stacked switch of the prior art and buting iron easily causes the shortcoming of the poor and equipment breakdown of Product Precision.
For achieving the above object, the invention provides a kind of device that utilizes absolute position to determine signal output, device comprises: transmission component, and it comprises driving link and driven member, driving link is fixed on the workbench of process equipment; Absolute value encoder, is fixed with driven member on the axle core of absolute value encoder, for determine the absolute position of workbench according to the motion of this driven member, and exports absolute position signal; PLC controller, it receives the absolute position signal of absolute value encoder transmission, and to process equipment, exports control signal according to absolute position signal.
Preferably, in technique scheme, transmission component comprises linear gear rack and gear, and linear gear rack is driving link, and linear gear rack is fixed on the workbench of process equipment, and gear is driven member, and gear is fixed on the axle core of absolute value encoder.
Preferably, in technique scheme, the control signal of PLC controller is required to determine by the processing technology of product.
Compared with prior art, the present invention has following beneficial effect:
Device of the present invention is by the definite absolute position transmission of signal of engagement of rack and pinion, signal transmission is reliable, without workbench, buting iron and stacked switch are triggered and transmission of signal, avoided triggering the adverse consequences that the faults such as inaccurate or triggerless are brought, signal transmission promptly and accurately, has guaranteed the machining accuracy of product; Meanwhile, the programming of the PLC controller of this device has expanded its scope of application, and apparatus structure is simple, easy for installation, it is flexible to control.
Accompanying drawing explanation
Fig. 1 is the structure chart that utilizes absolute position to determine the device of signal output according to of the present invention.
Main description of reference numerals:
1-absolute value encoder, 11-axle core, 2-linear gear rack, 3-gear, 4-bus, 5-PLC controller.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As shown in Figure 1, the device that utilizes absolute position to determine signal output according to the present invention comprises transmission component, absolute value encoder 1 and PLC controller 5.Transmission component comprises linear gear rack 2 and gear 3, and linear gear rack 2 is fixed on the process equipment workbench of (as reciprocation type is controlled special plane or transfer matic), with the movement of workbench, moves.Gear 3 and linear gear rack 2 engagements, and gear 3 is fixed on the axle core 11 of absolute value encoder 1.Absolute value encoder 1 is connected with PLC controller 5 by bus 4.
Preferably, bus 4 is Profibus DP bus.
PLC controller 5 can require to programme according to the processing technology of product, and the absolute value of predetermined site corresponding with each running status on linear gear rack 2 is set.If the overall length of linear gear rack 2 is 500m, apart from linear gear rack 2 zero point 200m position, need to export fast inlet signal; Apart from linear gear rack 2 zero point 300m position, need to export slow-motion signal; Apart from linear gear rack 2 zero point 350m position, need to export work inlet signal.That is: the absolute position that the first predetermined site is corresponding is 200m, and the absolute position that the second predetermined site is corresponding is 300m, and the absolute position that the 3rd predetermined site is corresponding is 350m.
During process equipment work, the mobile movement that drives linear gear rack 2 of workbench, under the engagement of linear gear 2 and gear 3, gear 3 rotates, absolute value encoder 1 obtains the absolute position of workbench on slide rail according to the rotation of gear 3, and the signal of absolute position is transferred to PLC controller 5, PLC controller 5 is exported corresponding control signal during to each predetermined site in movable workbench.That is: while being 200m in absolute position, output F.F. control signal; While being 300m in absolute position, output slow-motion control signal; While being 350m in absolute position, output work is entered control signal.
