Description
Technical field
The present invention designs a kind of automatic oil supply machine, specifically designs a kind of automatic oil supply machine of hydraulic tappet.
Background technique
In MDS system, the effect of hydraulic tappet is to realize the multi-cylinder free switching of engine, and hydraulic tappet is mounted on hair
Before in motivation, the high-voltage oil cavity of hydraulic tappet is needed full of oil, hydraulic tappet repairing at present lean on more push back and forth manually plunger into
Row repairing, because of the fatigue that large labor intensity and personnel work long hours, it cannot be guaranteed that each hydraulic tappet fills oil, therefore need
Artificial detection is carried out, and qualification rate can only achieve 85% or so, when single-piece work is 40 seconds, however detects and underproof also need
Again continue repairing, whole process is time-consuming and laborious and inefficiency.This method puts into high labor cost, personnel labor intensity
Greatly, product first-time qualification rate is low, it is difficult to meet the needs of industrialization.
Summary of the invention
The problem to be solved in the present invention is:
1. the high pressure chest repairing low efficiency using manpower to hydraulic tappet, the low problem of product qualification rate；
2. after the completion of repairing, needing to be detected again, process is complicated.
The technical solution adopted by the invention is as follows:
A kind of automatic oil supply machine of hydraulic tappet, which is characterized in that including frame, controller, driving device, push rod, fuel tank, control
Device and driving device are mounted on frame, and driving device is connected with controller, and fuel tank is mounted on the lower section of driving device, driving dress
It sets energy driving push rod to move up and down to push the plunger motion of hydraulic tappet vertically, push rod is installed far from one end of driving device
There is pressure sensor, pressure sensor is connected with the input terminal of controller, and the fixation of fixed hydraulic tappet is equipped in fuel tank
Device, counter can calculate the number that push rod pumps, timer can record pressure sensor from detect pressure to
Pressure reaches the time of setting pressure, and timer is connected with the input terminal of controller.
When driving device driving push rod moves downward, push rod is inserted into hydraulic tappet, pushes plunger to move downward, high pressure
Air in oil pocket is compressed, the gap discharge between plunger and cylinder, when pressure sensor detects between push rod and plunger
Pressure reaches the pressure value of setting, and driving device driving push rod moves upwards, and plunger is transported upwards under the action of reset spring
Dynamic, high-voltage oil cavity is because be discharged air, when plunger moves upwards, suction is generated in high-voltage oil cavity, the oil in fuel tank is inhaled
Enter into high-voltage oil cavity, high-voltage oil cavity completes a repairing, and then push rod continues to move back and forth, and high-voltage oil cavity is realized and repeatedly mended
Oil, until push rod is in a progradation, pressure sensor is little from the time for detecting that pressure reaches setting value to pressure
In setting time and counter detect push rod move back and forth number not less than setting minimum movement number when, be judged as
Hydraulic tappet repairing is completed.When filling oil in high-voltage oil cavity, push rod cannot push plunger to move again, and pressure sensor detects
Pressure moment reach the pressure value of setting, the time that timer record arrives at this time close to zero, therefore using the time of timer,
It may determine that whether hydraulic tappet fills oil.In order to avoid hydraulic tappet and push rod are due to location error, pressure sensor shifts to an earlier date
The pressure value for detecting setting causes high-voltage oil cavity repairing discontented, and the present invention also uses counter, auxiliary judgment hydraulic tappet
High-voltage oil cavity whether fill oil, improve the qualification rate of hydraulic tappet.Counter can use optical sensor technology, the every screening of push rod
The gear light that optical sensor issues twice, i.e. push rod move up and down once, count primary.The present invention may be implemented automatic repairing and
Detection, efficiency is fast, and qualification rate is high, can satisfy the demand of hydraulic tappet industrialization production.
Further, driving device is cylinder, and push rod is connected with the piston of cylinder, the height of the relatively fixed device of push rod away from
From adjustable.
Further, piston is equipped with adjusting nut, and rotating adjusting nut is adjustable the height of the relatively fixed device of push rod
Distance.
Further, the guide rail for adjusting fixed setting position is equipped in fuel tank.
Further, fixed device includes sleeve and chassis, and the internal diameter of sleeve and the outer diameter of hydraulic tappet match, chassis
It can be moved on guide rail.
A kind of oil supplement method of the automatic oil supply machine of hydraulic tappet, which comprises the following steps:
Step 1: hydraulic tappet is fixed in fuel tank with fixed device, the liquid level in fuel tank is higher than hydraulic tappet；
Step 2: being on button, and push rod at the uniform velocity moves downward under the drive of the drive, pushes the plunger of hydraulic tappet
It moves downward, pressure sensor detects that pressure, the pressure value that pressure sensor measures reach setting value, and driving device driving pushes away
Bar fast upward motion, push rod back and forth move up and down once, and counter counts primary；Timer record pressure sensor is from detection
Reach the time of setting pressure to pressure to pressure；
Step 3: when the number that the time that timer detects is not more than 0.1 second and counter detects is not less than 20 times, liquid
Tappet repairing is pressed to complete, controller controls driving device stop motion.
In conclusion the beneficial effects of the present invention are:
1. oil supply machine of the invention can be automatically performed repairing and detection, efficiency is fast, and oil supply machine structure is simple, easily generates
Manufacture；
2. giving hydraulic tappet repairing using the present invention, qualification rate is up to 99.5%, compared to the qualification rate 85% of manual repairing, significantly
It improves and also endures the successful qualification rate of the disposable repairing of tappet；
3. push rod extension elongation is adjustable, replaceable, convenient for being applicable in different parts.
