The detection precision is high, the incidence, the fallout ratio and the omission ratio of the non-drilling through hole on the glass product are reduced, and the labor intensity is also reduced. The utility model has lower requirements of the performances and the quality of the sensors. The structure is simple, the operation and the usage are convenient, and the detection is accurate and reliable, so the utility model is applicable to the modification of the existing numerical control glass drilling equipment, and the cost is very low.
Description
Technical field
The utility model relates to sets up a kind of penetrating status detection device of boring that detects in a kind of glass drilling machine.
Background technology
In the machining production line of glass, adopt at present numerical control glass drilling machine to the glass processing of holing usually, by motor and drill bit, hold-down mechanism, the drill bit propulsive mechanism, drill bit cooling device, frame and elevating screw etc. have been formed glass drilling equipment.Center at drill bit is provided with water delivering orifice, can cool off from the endoporus and the outside of drill bit.Earlier by the bit drills of the glass one side position to thickness of glass about 1/2, the drill bit by the glass opposite side oppositely gets out through hole then during boring.But this kind equipment adds man-hour holing, and owing to reasons such as bit wears, occurs the situation that the hole does not drill through sometimes, and this will directly have influence on the normal use of glassware.All be to rely on the artificial visually examine to check to the penetrating status detection of glass drilling at present, because tested workpiece is transparent glass, cause certain difficulty to desk checking, only whether the hole that is difficult to distinguish on glass with range estimation is through hole, wrong, omission situation often occur, cause harmful effect for glassware processing enterprise.
Summary of the invention
The purpose of this utility model is to detect the penetrating state in hole at existing glass drilling machine, and higher defective and the deficiency of manual detection loss proposes on a kind of glass drilling machine detecting the pick-up unit of boring permeability.It is simple in structure, and is easy to use, and reflection is sensitive, the accuracy of detection height.
The technical scheme that its technical matters that solves the utility model adopts is: on a kind of glass drilling machine to boring permeability pick-up unit, the cooling water pipeline that is connected with glass drilling machine through hole drill bit is provided with flow sensor and pressure transducer, or being provided with wherein a kind of sensor, the signal output part of described sensor is connected or is connected with Signal Monitor with numerical control device on the glass drilling machine.
Glass drilling machine needs water that drill bit is cooled off to glass drilling the time, and the type of cooling of existing numerical control glass drilling machine is to cool off by the cooling water hole water filling to bit central on the one hand, cools off from the bit exterior water filling on the other hand.When hole on glass is blind hole or does not have when drilled, the chilled water that injects from bit central is on a small quantity to the hole external leakage, and the flow of water is very little in the drill bit pipeline, can form certain pressure; When hole on glass was drilled through, chilled water went out from the hole underflow, and flow improves rapidly in the drill bit pipeline, and pressure reduces.According to this characteristic,, just can judge hole on glass and whether drill through by pressure and/or the variation of flow when holing that detects chilled water in the drill bit.
The utility model can also be provided with tensimeter and throttling valve by cooling water pipeline.
It is manual water valve that the utility model can also make throttling valve.
The beneficial effects of the utility model are: can increase at an easy rate on existing glass numerical control equipment, cost is low, detects reliable.
Therefore, compared with prior art the utlity model has following tangible advantage: 1, whether detect hole on glass with the signal of flow sensor, pressure transducer output in the drill bit cooling water pipeline drills through, its sensitivity is higher, the accuracy of detection height, reduce the incidence and wrong, the loss that do not drill through the hole on the glassware, also alleviated artificial visually examine's labour intensity.2, simple in structure, easy for operation, detect accurately and reliably, be suitable for existing glass drilling equipment is transformed, cost is extremely low.
Description of drawings
Fig. 1 is the line arrangement synoptic diagram of through hole drill bit cooling device in the utility model.
Among the figure: water pump 1, cooling water pipeline 2, operation valve 3, drill bit 4, pressure transducer 5, flow sensor 6, tensimeter 7, throttling valve 8, glass pieces 9, water tank 10.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
Referring to Fig. 1, on glass drilling machine, comprise numerical control device, drill bit 4 and the drill bit cooling device of forming by water tank 10, water pump 1, pipeline and operation valve 3, the water side of cooling water pipeline 2 is communicated with the cooling water pipeline at drill bit 4 centers in the drill bit cooling device.On a kind of glass drilling machine of the present utility model to boring permeability pick-up unit, the cooling water pipeline 2 that is connected with glass drilling machine through hole drill bit 4 is provided with flow sensor 6 and pressure transducer 5, or be provided with wherein a kind of sensor, as flow sensor 6 or pressure transducer 5 only are set.The signal output part of described sensor is connected or is connected with Signal Monitor with numerical control device on the glass drilling machine.
For stablizing the pressure and the flow of pipeline 2 internal water, the cooling water pipeline 2 between water pump 1 and the operation valve 3 is provided with tensimeter 7 and throttling valve 8.
The utility model is as follows to the penetrating status detection process of holing: after the boring beginning, at first start water pump 1, water pump 1 pumps into the water in the water tank 10 in the cooling water pipeline 2, chilled water is through in the cooling water pipeline in operation valve 3, pressure transducer 5 and/or the flow sensor 6 inflow drill bits 4, from the hole at drill bit 4 centers, flow out, drill bit 4 is cooled off.The amount of feeding of drill bit 4 and stroke are not subjected to the control of sensor by the set-point numerical control on drilling machine.When hole drill was logical, cooling water pressure descended in the cooling water pipeline 2, and flow increases, and sensor passes to primary controller with signal, and primary controller is made the judgement of " this hole drills through ", will can not interfere the execution of down-stream.Cover when the boring stroke that drilling machine is set, sensor does not also pass to primary controller with the signal of pressure and/or fluctuations in discharge, and primary controller is made the judgement of " this Kong Wei drills through ", and after drill bit 4 was return, primary controller sent signal and shuts down, and is handled by the people.To guarantee that each Kong Junyi that is bored drills through.The signal output part of sensor also can be connected with Signal Monitor, detects the penetrating state in hole during boring by the observation signal display.
