Abstract
The invention discloses a hydraulic tappet oil duct in a cylinder cover and a cleaning method of the hydraulic tappet oil duct. A blocking piece is fixedly arranged on the bottom end in the oil duct, and a closed chamber which is used for containing impurities is formed between the front end of the blocking piece and the bottom of the oil duct. The cleaning method comprises the steps of cleaning the oil duct without the blocking piece first, then installing the blocking piece, and then performing high-pressure cleaning on the oil duct. According to the hydraulic tappet oil duct and the cleaning method thereof, the problem that residual impurities generated when a cylinder cover long oil duct is processed are not easy to clean can be solved.
Description
Technical field
The present invention relates to automobile cylinder cover field, be specially a kind of cylinder cap hydraulic tappet oil duct and clean the method for this oil duct.
Background technique
In the motor using hydraulic tappet, often need for it arranges special oil duct, to meet the oil pressure requirement that it runs well, otherwise hydraulic tappet oil-filled insufficient time easily produce abnormal sound, therefore generally take the long oil road offering through cylinder to four cylinder at cylinder cap place, as shown in Figure 1, it comprises air inlet side long oil road 1 and exhaust side long oil road 2.
And long oil road also can bring series of problems, wherein the most seriously turbidity test requirement in oil duct cannot be ensured exactly.If turbidity test are poor, be easy to cause the stuck abnormal sound of hydraulic tappet.
Means the most frequently used at present install filter screen at hydraulic tappet place, detritus residual after filtering processing long oil road process.Oil duct filtrating equipment disclosed in Chinese patent 201220477533.5, a kind of exactly scheme that filter screen is set in oil duct.But the mode installing filter screen additional exists increases cost and the long-term unconspicuous problem of filtering effect.
In addition, be illustrated in figure 2 the cleaning method adopted at present for above-mentioned oil duct, it comprises four procedures.First be that workman carries out oil duct with long brush and scrubs, and then rinse with high-pressure cleaning liquid, inevitably being collected at the blind hole end place, bottom in long oil road owing to rinsing impurity in rear oil duct, therefore needing again with manually once scrubbing oil duct, finally carry out a highly pressurised liquid cleaning again.Visible, because oil duct length is longer, and one end is blind hole, therefore in order to impurity is effectively cleaned, existing cleaning method be provided with twice high-pressure wash and twice manual cleaning operation, waste time and energy, efficiency is not high, significantly increases labor strength.
Summary of the invention
The object of the present invention is to provide a kind of cylinder cap hydraulic tappet oil duct and cleaning method thereof, solve the problem of the residual impurity of cylinder cap long oil road processing not easy cleaning.
Cylinder cap hydraulic tappet oil duct of the present invention, is installed with type of tamper evidence in the bottom of described oil duct inside, forms one for the airtight chamber of accommodating impurity between bottom this type of tamper evidence front end and oil duct.
Preferably, described type of tamper evidence is threaded in described oil duct bottom.
Preferably, the rear end of described type of tamper evidence is provided with inner hexagonal hole.
Oil duct cleaning method of the present invention, is characterized in that comprising the steps:
By opening end, high-pressure wash is carried out by cleaning solution to the described oil duct formed after machining, now in oil duct, type of tamper evidence is not installed;
Then type of tamper evidence is added to bottom oil duct, in the airtight chamber that the impurity bottom oil duct is formed by shutoff bottom described type of tamper evidence and oil duct;
Install the oil duct after type of tamper evidence additional and carry out cleaning solution high-pressure wash to above-mentioned by opening end again.
Impurity bottom cylinder cap long oil road and shutoff are got up by type of tamper evidence by the present invention, decrease one manual cleaning operation, reduce labor strength, and can effectively improve oil duct turbidity test.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further elaborated, and following examples only for explaining the present invention, do not form limiting the scope of the present invention.
Cylinder cap hydraulic tappet oil duct as shown in Figure 3, Figure 4, comprises exhaust side long oil road 2 and air inlet side long oil road 1.The tapped hole of the bottom of described two oil duct inside is installed with type of tamper evidence 3.Tapped hole bottom above-mentioned oil duct is behind machining good air inlet side long oil road 1 and exhaust side long oil road 2, and little tapping drill bit processing that identical frock changes the outfit obtains.
See Fig. 5, the anterior periphery of described type of tamper evidence 3 is processed with outside thread 31, and its rear portion is provided with inner hexagonal hole 32.By inner hexagonal hole 32, this type of tamper evidence is threaded in oil duct bottom, form one between making bottom type of tamper evidence 3 front end and oil duct for the airtight chamber 4 of accommodating impurity, the length of this airtight chamber 4 is at more than 5mm.
See Fig. 6, for the cleaning method of above-mentioned oil duct, comprise the steps:
First, by opening end, high-pressure wash is carried out by cleaning solution to the described oil duct formed after machining, now in oil duct, type of tamper evidence is not installed.Therefore, after first cleaning, the partial impurities in oil duct can inevitably be stayed in the tapped hole of the bottom in long oil road by collection.
Then, type of tamper evidence is added to bottom oil duct, in the airtight chamber that the impurity bottom oil duct is formed by shutoff bottom described type of tamper evidence and oil duct, thus impurity and oil duct is isolated.
Again by opening end, cleaning solution high-pressure wash is carried out to the above-mentioned oil duct adding type of tamper evidence.
Visible, clear up with employing multiple working procedure, wishes scheme in the background technique of as far as possible impurity being discharged completely unlike, this programme is that inconvenient for the bottom impurity cleared up blocks by employing, then cleans oil duct.Therefore, decrease one manual cleaning operation, improve efficiency, reduce cost, ensure that oil duct turbidity test, avoiding in use oil pressure change to cause machine oil to impact drives impurity to rock back and forth in oil duct, thus brings to hydraulic tappet mounting hole 5 position that is communicated with oil duct and cause tappet clamping stagnation abnormal sound.
