Technical field
The utility model relates to a kind of device whether the die casting cast through holes dredges that detects, and belongs to casting technology field.
Background technology
In Die Casting, the outer profile size accuracy requirement of foundry goods is higher, therefore directly casting is selected out usually in a lot of screw thread via hole, oil circuit hole, cooling water hole etc., can reduce subsequent fine processing, raising production quality and efficient.But aging or each die cavity coordinates not closely due to mould, and the die casting defectives such as burr, bark pocket can appear in the cast through holes mating surface, cause through hole obstructed, cause functional inefficacy.At present, the means whether the detection cast through holes dredges are generally range estimation or more complicated infrared induction, and range estimation is subjected to easily undetected, the false retrieval problem of appearance of operating personnel restriction itself; Although infrared induction detects and can effectively detect, input cost is large, and structure is more complicated, and maintaining requires high.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of device whether the die casting cast through holes dredges that detects, and effectively avoids undetected, false retrieval problem, and detection efficiency is high, and simple in structure, and is easy and simple to handle, and maintaining is simple and easy, and input cost is low.
To achieve these goals, the technical solution adopted in the utility model is: a kind ofly detect the device whether the die casting cast through holes dredges, power supply is installed on insulating base, detects cylinder, reversal valve, display lamp, test rod and metal aperture; Described metal aperture is opened on insulating base; One end of power supply is connected with display lamp by power switch, and this end of power supply is connected with the detection cylinder by power switch and reversal valve simultaneously; Detecting cylinder is connected respectively the other end by pneumatic switch, solenoid valve and mistake proofing switch and is connected with power supply with metal aperture; Detecting simultaneously cylinder is connected with test rod by the mechatronics line; Test rod is connected with display lamp again simultaneously; The diameter of described test rod is slightly less than the diameter of the cast through holes of foundry goods to be detected, and the cast through holes of test rod and foundry goods to be detected is coaxial.
Circuit between power supply and mistake proofing switch is provided with alarm buzzer.
Circuit between alarm buzzer and metal aperture is provided with power light.
This device also comprises locking cylinder.
This device adopts easy basic circuit principle, the closure of circuit whether with the dredging of foundry goods through hole complete dependence whether, but and by the display lamp of setting in installing and the effect that alarm buzzer reaches operating personnel's intuitive judgment, thereby compare with before range estimation or infrared induction, having the detection accurate stable, detection efficiency is high, simple in structure, easy to operate, input cost is low, the easy advantage of maintaining.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the device whether this detection die casting cast through holes dredges is characterized in that, power supply 1 is installed on insulating base 16, detects cylinder 5, reversal valve 6, display lamp 7, test rod 8 and metal aperture 9; Described metal aperture 9 is opened on insulating base 16; One end of power supply 1 is connected with display lamp 7 by power switch 2, and this end of power supply 1 is connected with detection cylinder 5 by power switch 2 and reversal valve 6 simultaneously; Detecting cylinder 5 is connected with the other end that metal aperture 9 is connected with power supply respectively by pneumatic switch 3, solenoid valve 13 and mistake proofing switch 12; Detect simultaneously cylinder 5 and are connected connection with test rod by mechatronics line 4; Test rod 8 is connected again connection simultaneously with display lamp; The diameter of described test rod 8 is slightly less than the diameter of the cast through holes of foundry goods 15 to be checked, and the cast through holes of test rod 8 and foundry goods to be checked 15 is coaxial.
As improvement of the present utility model, be provided with alarm buzzer 11 on the circuit between power supply 1 and mistake proofing switch 12, because in practical operation, operating personnel are as only very large by observing the workload that display lamp 7 judges that whether the die casting cast through holes dredge, unavoidably can be because fatigue causes erroneous judgement, therefore increase alarm buzzer 11 in this pick-up unit, in case detect product, problem is arranged, sharp-pointed buzzing chimes of doom just can be reminded operating personnel at once, alleviate operating personnel's work visual fatigue on the one hand, can greatly improve the accuracy of the examination and test of products on the other hand.
Improve as of the present utility model another, be provided with power light 10 on the circuit between alarm buzzer 11 and metal aperture 9, because in operating process, can run into unavoidably the situation of power cut-off, at this moment, device can't be worked.In the situation that power light 10 is not set, operating personnel can not judge at once power cut-off and cause or detect dress
Put out of jointly, can help the open-and-shut problem of judging of operating personnel to go out at which therefore establish this power light 10, improve operating personnel's work efficiency.
One improve again as of the present utility model, can also be provided with locking cylinder 14 on the circuit of this device, locking cylinder 14 enters duty in detecting cylinder 5 in advance as quick-locking device, and foundry goods 15 is tightly pinned, prevent its slip, provide more stable working environment for detecting cylinder 5, improve the accuracy and the reliability that detect, simultaneously, compare with artificial locking, can greatly improve the work efficiency of whole testing process.
during use, foundry goods 15 to be checked and pick-up unit are placed on insulating base 16, the positive pole of power supply 1 is connected with test rod 8, the negative pole of power supply 1 is connected with metal aperture 9, guarantees that foundry goods 15 to be checked is in place fully, and this moment, foundry goods to be checked 15 bottoms contacted fully with metal aperture hole 9, mistake proofing switch 12 closures, if foundry goods 15 to be checked is not put into the position fully, mistake proofing switch 12 can be not yet can not be closed, therefore mistake proofing switch 12 plays simultaneously and prevents that foundry goods 15 to be checked from putting and tiltedly put inclined to one side effect, after mistake proofing switch 12 closures, solenoid valve 13 gets electric, start pneumatic switch 3, whole device ventilation, reversal valve 6 starts simultaneously, drive locking cylinder 14 work, with foundry goods 15 lockings to be checked, examining cylinder 5 promotion test rods 8 this moment enters in foundry goods 15 cast through holes to be checked, if cast through holes is obstructed, one or more test rod in test rod 8 contacts with foundry goods 15 to be checked, be that both positive and negative polarity links together, form closed electric loop, in display lamp 7 on corresponding loop one or many display lamps are bright at this moment, alarm buzzer 11 buzzings are reported to the police, be that product is defective, need do over again, if cast through holes is led to, test rod 8 is all accessible to be passed through smoothly, is in off state, and display lamp 7 does not work, and alarm buzzer 11 does not ring, and product is qualified.Slewing directional control valve 6, test rod 8 sets back, and detects and finishes.
