Description
Technical field
The utility model relates to the device whether a kind of hole on on-line checkingi automobile punching part lacks, and belongs to detection technique field.
Background technology
There will be the situation of drift wearing and tearing or drift fracture after punching die Long-Time Service, cause the disappearance in workpiece upper part hole.For the streamline of production punching part, if this situation can not Timeliness coverage, a large amount of waste products will be there is in a short period of time, cause very large loss to enterprise, therefore be necessary to carry out on-line checkingi to the hole on workpiece.For many auto parts and components, its production line generally comprises the operations such as punching, roll-forming, welding (the product welding operation had), cut-out, traditional detection method detects after all process steps completes again, and be sampling observation, namely allow to Timeliness coverage product defects, also there will be more waste product.Therefore, the percent defective how effectively reducing punching part is a puzzlement relevant technologies personnel's difficult problem always.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of on-line measuring device of automobile punch workpiece, and with Timeliness coverage product defects, rate of reducing the number of rejects and seconds to greatest extent, reduces the economic loss of enterprise.
Problem described in the utility model realizes with following technical proposals:
A kind of on-line measuring device of automobile punch workpiece, formation comprises signal processing circuit, probe fixed head and multiple fiber switch, parallel with by the plate workpiece of punching in the frame that described probe fixed head is fixed on punching apparatus, the fibre-optical probe of described multiple fiber switch to be fixed on probe fixed head and with the hole one_to_one corresponding on workpiece, the signal output part of multiple fiber switch connects the different inputs of signal processing circuit respectively.
The on-line measuring device of above-mentioned automobile punch workpiece; described signal processing circuit comprises PLC and touch-screen; described touch-screen connects the communication interface of PLC by RS485 communication cable; the signal output part of multiple fiber switch connects the different input ports of PLC respectively; the P002 port of described PLC connects the stopping feed signal of the servo feeding system output of punching apparatus, and the disorderly closedown signal of the P003 port output of PLC sends into the input of servo feeding system.
The on-line measuring device of above-mentioned automobile punch workpiece, also failure alarm circuit is comprised in formation, described failure alarm circuit comprises alarm lamp and relay, control coil one end ground connection of described relay, the P020 port of another termination PLC, the normally opened contact of relay is serially connected in the control loop of alarm lamp.
The on-line measuring device of above-mentioned automobile punch workpiece, also comprises start button and stop botton in formation, one end ground connection of described start button and stop botton, and the other end connects P000 and the P001 port of PLC respectively.
The utility model utilization and the hole in punch workpiece one to one multiple fiber switch are detected workpiece, not only achieve the online automatic detection of punch workpiece, avoid the lasting appearance of waste product, and accurately can locate the hole of leaking punching, the rapid-maintenance for equipment is provided convenience condition.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is electrical schematic diagram of the present utility model;
Fig. 2 is the scheme of installation of fibre-optical probe.
In figure, each label is: 1, workpiece; 2, hole, 3, probe fixed head, 4, fibre-optical probe; PLC, programmable controller; GK1 ~ GKn, the first fiber switch ~ the n-th fiber switch, CM, touch-screen, SL, servo feeding system; L, alarm lamp; J, relay, S1, start button, S2, stop botton.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, the utility model comprises signal processing circuit (comprising PLC, touch-screen CM, alarm lamp L, relay J, start button S1 and stop botton S2), multiple fiber switch (GK1 ~ GKn) and probe fixed head 3.Fiber switch is a kind of contactor of non-contact type, forms primarily of luminous tube, fibre-optical probe, photo-detector, amplifier and switching signal output element.The fibre-optical probe 4 of fiber switch is fixed on probe fixed head 3, and the signal collected is delivered to the unlike signal input of PLC by fiber switch.
Probe fixed head 3 is fixed on the front portion of servo feeder, the hole one_to_one corresponding on the installation site of each fibre-optical probe 4 and detected workpiece 1.In fig. 2, the hole on workpiece 1 has 10, and each hole arranges a fibre-optical probe 4, need install 10 fibre-optical probes 4 altogether.
The course of work of the present utility model is as follows: in equipment running process, if the stopping feed signal that the servo feeding system that the P002 port of PLC receives punching apparatus sends (namely single product runs the signal that puts in place), illustrate that a workpiece punching is complete, align with corresponding fibre-optical probe 4 in hole on workpiece, now PLC reads the output signal of each fiber switch, and whether the hole judging on workpiece accordingly exists leakage rushes phenomenon.If certain fibre-optical probe can not detect the existence in hole, illustrate that punching is leaked in the hole that this fibre-optical probe is corresponding, now PLC exports disorderly closedown signal by P003 port, makes servo feeding system out of service, doing so avoids the lasting appearance of waste product.If detect without any fibre-optical probe and leakage rush phenomenon, then PLC automatically resets, and waits the detection of next product pending.
PLC also sends alarm signal by failure alarm circuit after detecting and leakage rushing phenomenon, and prompting staff fixes a breakdown in time, resumes production as early as possible.
Touch-screen CM is for showing Detection Information and carrying out optimum configurations, and staff, by observing touch-screen, can judge that specifically problem has appearred in which hole, creates convenience with regard to the rapid-maintenance for equipment like this.
The utility model structure is simple, easy to operate, be easy to realize.What adopt the utility model that human factor can be avoided to cause is undetected, thus considerably reduces percent defective.
