Abstract
Qingdao Zi Chai Bo Yang diesel engine CO. Ltd. introduces an N330-series diesel engine from Yang Ma joint-stock company of Japan in 2004. In the assembling process of an N330-series diesel engine oil adjusting shaft, processing a pin hole is a technical problem, i.e., processing of the pin hole for the oil adjusting shaft is realized by adopting special equipment in the Yang Ma joint-stock company of Japan, but only can be manually realized in China due to domestic condition limitations; manually processing the pin hole comprises mounting an oil adjusting shaft part on the diesel engine and then drilling with an electric hand drill, and the defects for drilling with the electric hand drill are poor quality, low efficiency and high cost. To solve the problem, the invention provides an N330 diesel engine oil adjusting shaft pin hole processing method; according to the method, processing equipment is designed and made, a state that the N330-series diesel engine oil adjusting shaft is mounted on the diesel engine is simulated in advance, then the N330-series diesel engine oil adjusting shaft is mounted and fixed on the processing equipment, and the pin hole is processed with a mobile bench drill, thus solving the problem of processing the pin hole in the assembling process of the N330-series diesel engine oil adjusting shaft.
Description
technical field
The present invention relates to the dowel hole processing method that 6 cylinders peculiar to vessel or 8 cylinder diesel engine fuel feed mechanisms adjust oily axle and part mounted thereto.
prior art and background technology
Qingdao Zichai Boyang Diesd Engine Co., Ltd. has introduced high-power medium speed N330 marine diesel from Japanese Yanmar Diesel Engine Co. Ltd. in 2004.In diesel engine production process, that adjusts oily spindle unit is assembled into a technical barrier.Adjust oily spindle unit to be one of parts on diesel engine, be arranged in (as shown in Figure of description 1) before each cylinder injection pump in diesel engine control side.Oily axle is adjusted to be slender axles.By adjusting the fine rotation of oily axle, driving and adjusting the anchor tip on oily axle to rotate, anchor tip is stirred the first control stick and is rotated the fuel delivery making the pull-out of injection pump dipstick and stretch into regulate injection pump.Anchor tip needs to be fixed on certain angle to adjust on oily axle, and adjusts oily axle jointly hole and install alignment pin.In a pre-installation, to determine that the first control stick is along adjusting the axial installation site of oily axle, will determine that the first control lever shaft is along the scope of activities adjusting oily Axial and radial on the other hand on the one hand.The oily axle of tune and anchor tip correctly to be installed and processed pin-and-hole and have two kinds of modes.First kind of way: the part adjusted on oily axle is installed on diesel engine together with the oily axle of tune, regulates draw-bore behind the position of dipstick pull bar and anchor tip.The second way: the installation site when part that simulation adjusts oily axle to fasten works on a diesel engine, will adjust oily shafting installation to (as shown in Figure of description 2) on diesel engine after regulating the position draw-bore of dipstick pull bar and anchor tip.
goal of the invention
The object of the invention is to solve by scheme described in summary of the invention the problem that N330 serial diesel engine adjusts oily pin hole difficult processing, before application of the present invention, the Working position of oily axle and anchor tip is adjusted to determine, above-described second way pin hole processing can only be adopted, namely adjust oily shafting installation to process afterwards on a diesel engine.This kind of processing method has following drawback: 1. affect product quality.The iron filings that pin hole processing produces on the clean diesel engine assembled can pollute machine.2. time-consuming.Pin hole processing carries out with electric hand drill on a diesel engine, slender axles owing to adjusting oily axle, material is that No. 45 steel have carried out modulation treatment, very difficult with drilling of electric hand drill, needs to hold electric hand drill by 1 people, other 2 personal lever pressing electric drills, often process a hole and need 30 minutes, for 8 cylinder diesels, only install and adjust oily axle system just to need 4 hours, in production task comparatively busy, such efficiency of assembling allows people be difficult to tolerance.3. require great effort.Limited space on diesel engine, 3 people's pin hole processings are very awkward, can't put on a spurt, and difficulty of processing is very large.In view of the above circumstances, this processing scheme has been invented in design.
summary of the invention
Direction of the present invention adopts above-described first kind of way.Method is: diesel engine is adjusted the anchor tip on oily axle and adjust oily axle to process with the special equipment of pin hole processing, processing method is as follows:
1, the anchor tip of diesel engine, the first control stick and thrust housing are arranged on (as shown in Figure of description 3) on the oily axle of tune.2., will oily axle and dress part thereon be adjusted to be arranged on drill jig frame according to correct position and to fix.(oily axle is adjusted to be placed on drill jig frame for whole, compression adjusts the spring on oily axle to be fixed in the U-type groove of drill jig frame by the part adjusted on oily axle, being pulled off by first control stick is stuck on location-plate, can determine axis and the radial position of adjusting each part on oily axle after installing the pressing plate on the left of U-type groove.3. the bushing plate installed above drill jig frame can adjust oily axle and anchor tip, thrust housing pin-and-hole to process (as shown in Figure of description 4) to each cylinder by mobile bench drill on guide rail.The present invention is the combination of a kind of method and equipment, and it is key point of the present invention that the part adjusted on the oily axle simulation operating position of installing on a diesel engine is processed dowel hole.

Fig. 3 adjusts oily spindle unit work sheet;
Fig. 4 is that oily pin hole process unit figure adjusted by N330 diesel engine.
Claims (2)
1. are a kind of methods that the N330 of processing serial diesel engine adjusts oily pin hole; It is characterized in that: adjust the part " the first control stick, anchor tip and thrust housing " on oily axle to be contained in advance by whole for N330 diesel engine and adjust on oily axle, to be fixed on adjusting oily axle and installing superincumbent part on the drill jig frame that designs and produces according to its duty integral installation on a diesel engine, utilizing can the oily pin hole of bench drilling processing tune of movement on the guide rail of drill jig frame side.
2. drill jig frame is used to install and the oily shaft support of fixing tune, and 8 cylinder diesels use 4 supports altogether, and 6 cylinder diesels use 3 supports altogether, and the oil supply mechanism of every 2 cylinders uses 1 support, 4 equidistant installations of support; Drill jig frame adopts HT250 cast, machines rear fixing on the table according to design drawing.
