A kind of grease coating machine
Technical field
The present invention relates to a kind of grease coating machine, particularly a kind of grease coating machine when being used for engine production.
Background technology
When the engine of producing, be the sealing of installing between assurance bent axle and the casing, general employing is pressed into oil sealing and guarantees sealing.Need coat grease in the groove of oil sealing inwall before oil sealing is installed, with the sealing of increase engine and the wearability of bent axle, what adopt at present is manual oiling and pneumatic oiling:
(1) manually oiling: it is coated onto grease in the groove of oil sealing inside with hand or other utensils.Its defective is: 1, the activity duration oversize, 2, the quality of goods can not get guaranteeing, 3, the cleaning of operation field is bad;
(2) pneumatic oiling: its directly injects grease in the large-scale cylinder with high pressure grease pump, by an amount of air pressure the grease in the cylinder is pressed onto on the anchor clamps then, thereby finishes oiling to oil sealing.Its defective is: 1, mixing air in the cylinder, air cannot be discharged, and it is fuel-displaced undesired to cause, and the fuel-displaced time is poorly controlled, and time is lacked for a long time, and changes greatly in the pressure lower volume, and the return of cylinder is bigger, and fuel-flow control is had a significant impact; 2, the thickness of grease seriously influences oil pump capacity, the density of grease not simultaneously, oil pump capacity is also different; 3, the variation of ambient temperature causes variable density, thereby the thickness of grease is had a strong impact on, thus cause fuel-displaced undesired.
Summary of the invention
The present invention relates to a kind of grease coating machine, it not only can guarantee fuel-displaced unimpeded, and can accurately control oil pump capacity, guarantees the unanimity of oil pump capacity.
The present invention has adopted following technical scheme: a kind of grease coating machine, it comprises butter filler, oil water separator and fat liquoring anchor clamps, it also comprises proportional valve, magnetic valve and monitoring device, the output of described oil water separator is connected with the pressure-reducing valve of butter filler, the oil-out of butter filler is connected by high-pressure oil pipe I with the oil-in of proportional valve, the hydraulic fluid port I that tells of proportional valve is connected by high-pressure oil pipe II with the fat liquoring anchor clamps, between the pressure-reducing valve of oil water separator and butter filler, be connected with pipeline, pipeline is connected with the input of magnetic valve, the output of magnetic valve is connected with the input control end of proportional valve, described monitoring device and fat liquoring anchor clamps top to tell hydraulic fluid port II adjacent, monitoring device is corresponding with magnetic valve, monitoring device sends to magnetic valve after detecting the signal of telling hydraulic fluid port II place oil sealing, and the control proportional valve was fuel-displaced after magnetic valve received signal.
Described butter filler is the high-pressure pneumatic butter filler.Described monitoring device is set to two photoelectric sensors, to tell hydraulic fluid port II adjacent with two of fat liquoring anchor clamps top respectively for two photoelectric sensors, two photoelectric sensors are for being connected in parallel, the A end that is provided with magnetic valve one end after the two photoelectric sensor parallel connections is corresponding, the A of two photoelectric sensors and magnetic valve end is normally closed during work for often opening, and is provided with B at the other end of magnetic valve and holds, the B of magnetic valve end is for normally closed, during work for often opening.Described magnetic valve is the 3 position-5 way magnetic valve.
The present invention has following beneficial effect: two of fat liquoring anchor clamps of the present invention top is told hydraulic fluid port II place and is provided with two photoelectric sensors respectively, be connected with magnetic valve on the pipeline between oil water separator and the grease pump, the input of magnetic valve is connected with pipeline, output is connected with proportional valve, when oil sealing is placed on telling hydraulic fluid port II and going up of fat liquoring anchor clamps, photoelectric sensor monitors the signal of oil sealing and sends signal to magnetic valve, magnetic valve is in closure state, the fat liquoring anchor clamps under the control of proportional valve in oil sealing grease, can avoid so directly grease being pressed into air is entered in the high-pressure oil pump, thereby control fuel-displaced time and oil pump capacity effectively, guarantee unobstructedly fuel-displacedly, and can improve fuel-displaced mobility of proportional valve and accuracy.Two photoelectric sensors of the present invention are for being connected in parallel, be separate between two photoelectric sensors, as long as wherein any one photoelectric sensor monitors signal and all can make magnetic valve be in normally off, control proportional valve fuel feeding, thus can guarantee carrying out smoothly of fuel feeding process.The present invention adopts the high-pressure pneumatic butter filler, between high-pressure pneumatic butter filler and fat liquoring anchor clamps, be provided with proportional valve, it can control oil pump capacity by proportional valve, so not only can accurately control the size of oil pump capacity, and the influence that not changed by grease density and ambient temperature.

Fig. 1 is a structural representation of the present invention
The specific embodiment
In Fig. 1, the present invention is a kind of grease coating machine, it comprises butter filler 1, oil water separator 2, fat liquoring anchor clamps 3, proportional valve 4, magnetic valve 5 and monitoring device, proportional valve 4 is a FA101 proportional valve 4, its oil pump capacity is 0.1ml-1ml, magnetic valve 5 is the 3 position-5 way magnetic valve, butter filler 1 is a high-pressure pneumatic butter filler 1, the output of oil water separator 2 is connected with the pressure-reducing valve 6 of butter filler 1, the oil-out 14 of butter filler 1 is connected by high-pressure oil pipe I 8 with the oil-in 7 of proportional valve 4, the hydraulic fluid port I 9 that tells of proportional valve 4 is connected by high-pressure oil pipe II 10 with fat liquoring anchor clamps 3, between the pressure-reducing valve 6 of oil water separator 2 and butter filler 1, be connected with pipeline 11, pipeline 11 is connected with the input of magnetic valve 5, two outputs of magnetic valve 5 are connected with the input control end of proportional valve 4 respectively, monitoring device is two photoelectric sensors 13, to tell hydraulic fluid port II 12 adjacent with two of fat liquoring anchor clamps 3 tops respectively for two photoelectric sensors 13, two tell hydraulic fluid port II 12 can be the oil sealing oiling of different-diameter, two photoelectric sensors are for being connected in parallel, the A end that is provided with magnetic valve one end after the two photoelectric sensor parallel connections is corresponding, the A end of two photoelectric sensors and magnetic valve is for often opening, be normally closed during work, the other end at magnetic valve is provided with the B end, magnetic valve B end is for normally closed, during work for often opening, in two photoelectric sensors any one has induction after monitoring signal, just send signal and give the A end of magnetic valve, the A termination of magnetic valve 5 receives behind the signal to normally closed, so just can connect to tell hydraulic fluid port I 9 and make proportional valve 4 fuel-displaced in fat liquoring anchor clamps 3.When not having oil sealing to be placed on to tell on the hydraulic fluid port II 12, after photoelectric sensor 13 did not monitor the signal of oil sealing, magnetic valve 5 just was under the another one signal, and magnetic valve B end is for normally closed, can make high pressure butter filler 1 to proportional valve 4 fuel feeding fat like this, proportional valve 4 just is in oil-filled state.
