Description
Technical field
The present invention relates to a kind of methods of combustion lubricating oil pump control mechanism reconfiguration closure shell, belong to shell mounting technology field.
Background technique
The shell of combustion lubricating oil pump control mechanism is made of governor body and case cover, when overhaul, often due to lid
The faying face that shell wears or matches with governor body has wound, it cannot be guaranteed that leakproofness, it is therefore desirable to closure shell be reconfigured
Body.Conventional process flow is by hand with lead plug sub-aperture on governor body and case cover, and then pressing, guarantee are final again
Matching requirements.However, reconfiguration case cover on pinhole and governor body on pin coordinate it is inconsistent, to lead
Assembly Interference is caused, assembly is unable to complete.
Summary of the invention
The present invention provides a kind of method of the high combustion lubricating oil pump control mechanism reconfiguration closure shell of simple process, assembly precision,
Case cover assembly to guarantee governor body and reconfiguration is qualified, with overcome the deficiencies in the prior art.
Technical solution of the present invention: a method of closure shell is reconfigured in combustion lubricating oil pump control mechanism, comprising the following steps:
(1) centre bit in the machined hole of any two on governor body is accurately measured first on three-coordinates measuring machine
It sets, then using the line of centres in two machined holes as Y-axis, using the center in one of them machined hole as coordinate origin,
To pass through the coordinate origin and the straight line vertical with Y-axis as X-axis, rectangular coordinate system is established, is established in rectangular coordinate system at this
Measure the actual coordinate value of pin on governor body；
(2) it will be fixed on the workbench of vertical machining centre with governor body with the closure shell made, in closure shell
Two machined holes corresponding with governor body are found out on body, then according to the method for step (1) and machined with the two
Hole is established and step (1) identical rectangular coordinate system, and the actual coordinate value of the pin then obtained according to step (1) is at the right angle
The coordinate value that corresponding pin hole is found out in coordinate system, according to the coordinate value for the pin hole found out to pin hole in closure shell
Carry out roughing；
(3) closure shell is transferred on three-coordinates measuring machine, the pin on three-coordinates measuring machine after repetition measurement roughing
The coordinate value of the pin hole is compared, if coordinate by the coordinate value in hole with the actual coordinate value of pin on governor body
Pin hole can then be finished and be formed within the scope of the maximum allowance of pin hole by value difference value；
(4) in vertical machining centre then closure shell is connected and fixed by the pin hole machine-shaping in closure shell
On governor body, pin is finally pressed into pin hole.
In the above method, before vertical machining centre processes pinhole, by paving the method for low spot come centering closure shell
The faying face that body is matched with governor body makes the flatness of the faying face in closure shell be less than 0.02mm.
Due to the adoption of the above technical scheme, the present invention has the advantages that the present invention passes through in governor body and closure shell
Identical rectangular coordinate system is established on body, pin actual coordinate value on governor body can excessively be arrived in closure shell in this way
In the rectangular coordinate system of upper foundation, the coordinate value of pin hole in closure shell is obtained, it in this way can be by the coordinate value of the pin hole
Vertical machining centre is imported, by vertical machining centre by pin hole machine-shaping.Therefore, by means of the present invention in lid
The pin hole processed on shell, to improve assembly precision, can be protected with the pin perfect cooperation on governor body
Demonstrate,prove the qualification rate of the case cover assembly of governor body and reconfiguration.

Specific embodiment
In order to keep the object of the invention, technical solution and advantage clearer, with reference to the accompanying drawings and examples to the present invention
It is described in further detail.
The embodiment of the present invention: the method for combustion lubricating oil pump control mechanism reconfiguration closure shell, comprising the following steps:
(1) the on governor body 5 first machined hole 1 and second is accurately measured first on three-coordinates measuring machine to have added
The center in work hole 2, then using the line of centres in the first machined hole 1 and the second machined hole 2 as Y-axis, with second
The center for processing hole 2 is used as coordinate origin, to pass through the coordinate origin and the straight line vertical with Y-axis is as X-axis, establishes right angle and sits
Mark system, in the actual coordinate value for establishing the first pin 3 and the second pin 4 on measurement governor body 5 in rectangular coordinate system；
(2) it will be fixed on the workbench of vertical machining centre with governor body 5 with the closure shell 10 made, in lid
The machined hole 6 of corresponding with governor body 5 third and the 4th machined hole 7 are found out on shell 10, then according to the side of step 1
Method and with the machined hole of third 6 and the 4th machined hole 7 establish with step (1) identical rectangular coordinate system, further according to step (1)
The actual coordinate value of the first pin 3 and the second pin 4 that obtain finds out corresponding first pin hole, 8 He in the rectangular coordinate system
The coordinate value of second pin hole 9 carries out roughing to pin hole in closure shell according to the coordinate value for the pin hole found out；?
Before vertical machining centre processes pinhole, matched by paving the method for low spot come centering closure shell 10 and governor body 5
