Description

Lubricating oil is supplied with the micro-computer controlling apparatus of machine

The utility model relates to the micro-computer controlling apparatus that a kind of lubricating oil is supplied with machine, especially refer to a kind of storage chip that utilizes microprocessor to cooperate periphery, show that circuit such as indication and setting control carry out the action of oiling, have function control devices such as oil starvation breaking alarming and pressure detection simultaneously.

General power machine is for keeping normal operation, and the lubricating oil of just must annotating on parts at set intervals is to keep the smooth and easy of parts running; And the work of tradition filling lubricating oil adopts manual type to carry out more, time and effort consuming not only, and efficient is not high, so there is the automatic oiling machine to come out, its structure as shown in Figure 1, it mainly covers a lid 11 in oil groove 10 tops, be provided with intermittently time cycle controller 12 in lid 11, pouring orifice 13, oil-out 14 and motor 15 etc., wherein the oil pump 16 of oil groove 10 inside is located in these motor 15 connections one, be provided with a pressure-regulating valve 18 and a level switch 19 in addition in oil groove 10 inside, this oil pump 16 is behind the lubricating oil that the set oil pumping mouth 17 in bottom extracts in the oil groove 10, be delivered to oil-out 14 through pressure-regulating valve 18, with to the lubricated action of the mechanism for implementing of oil-out 14 correspondence positions, its oiling time and quiescent interval then by intermittence time cycle controller 12 mechanical timer set, with the control lubrication interval.

Manually carry out the oil injecting lubricating action though above-mentioned automatic oiling machine can replace, yet still have following shortcoming on its structural design:

(1) time cycle controller at intermittence because of control oiling time and quiescent interval designs for mechanical type, and because of this at intermittence time cycle controller and motor all be fixed on the lid, so the vibromotive force that motor running is produced will influence the accuracy of this mechanical timer, and then cause oiling time and quiescent interval to depart from setting value, influence lubricant effect and may undermine parts.

(2) be soaked in the lubricating oil in the oil groove because of its most pipeline component such as oil pump, pressure-regulating valve, level switch and oil pipe etc. all are installed in, also accumulate grease after long-term, cause the inconvenience in the cleaning, and more because of the pipeline component of oil groove, easily produce generating collision and cause bigger operating noise in when running.

(3) be located in the oil groove because of pressure-regulating valve, when desire is adjusted charge oil pressure, lid must be unloaded from oil groove, can adjust smoothly, the quite inconvenience that build-up of pressure is adjusted.

Because traditional automatic oiling machine has the disappearance in the said structure design, so the producer develops the automatic oiling machine of microcomputerized control, utilize the micro computer storage chip to set oiling time and quiescent interval, to solve the disappearance that mechanical timer is derived, and general micro computer oiling machine is all only paid attention to the design of time set aspect, fail to study, cause its function to fail to reach perfection with regard to oiling machine situation such as contingent oil starvation or oil circuit obstruction when using.

Because oiling machine is for keeping the normally moving importance of changeing of plant equipment, and that conventional apparatus is not attained in the design of structure and function is perfect, order of the present utility model is to provide a kind of lubricating oil to supply with the micro-computer controlling apparatus of machine, it is except that utilizing microcomputerized control oiling time and quiescent interval, other gives one group of oil starvation alarm and one group of pressure detector, to detect the situation of oil circuit, avoid its oil injecting lubricating action of oil circuit problems affect, its function is more reached perfection and improves its practicality to be worth.

Supply with the micro-computer controlling apparatus of machine according to a kind of lubricating oil of the present utility model, form by circuit such as microprocessor and connected storage chip, setting demonstration and drive controlling, by setting display circuit with in required oiling time and the quiescent interval input storage chip, and microprocessor is obtained the time value of setting in storage chip, actuate the running of this drive control circuit motor according to the control of time, carry out oil injecting lubricating or intermitten with motor transmission oil pump again; This device is provided with one group of oil starvation alarm and one group of pressure detector, this oil starvation alarm all links to each other with a terminal of microprocessor with a terminal respectively with pressure detector, and another terminal is connected with a terminal of Drive and Control Circuit, this oil starvation alarm has one to detect the whether floating switch of oil starvation of oil groove, and this pressure detector is to detect the device whether oil circuit circulates whether to reach predetermined pressure in the stipulated time; When oil groove oil starvation or oil circuit insufficient pressure, signal capable of feedback gives microprocessor, and the control motor stops operating and the sounding warning automatically, and after oiling or fault are got rid of again, motor is turned round again.

The utility model utilizes a floating switch to detect whether oil starvation of oil groove, and with oil starvation alarm line, except that the sounding warning, can control motor automatically in addition and shut down, with prevent to cause by oil starvation the oiling action can't carry out and the parts of motor idle running impaired etc.

In addition, utilize this pressure detector to detect oil circuit and whether circulate, when the oiling time is decremented to zero, oil circuit can be transferred to intermittently state, and sounding warning when insufficient pressure, note to remind operating personnel.
