Embodiment
With reference to Figure of description, the present invention is further elaborated.
A kind of band coating casing processing method of thin-walled of the present invention, comprises the following steps：
The processing route of wheel chamber casing is that internal critical size will be related to the size subsequently assembled in smart car process
(groove depth, groove width and the groove thickness of such as T-slot) stays 0.3mm~0.5mm surpluses；
Implement spraying process, carry out the processing of remaining surplus after process to be sprayed by car coating procedure again, with to
Disappear the impact of blast, spraying process to housing in spraying process；
The Vehicle Processing of critical size inside wheel chamber casing is carried out after the machining of remaining surplus.
Before spraying process wheel chamber casing inner mold face or assembling T-slot in install elastomeric material filler with offset spraying,
Blast work step controls the deflection of part under end-state to the impact force of part.
In car coating procedure, the processing dimension of coating is adjusted, car is carried out when grinding coating using arc-shaped structure
Processing, in the case where meeting design requirement, the coating tolerance provided according to design is processed, and coating centre position is processed into
Apply thickness point.
The processing dimension of coating is adjusted for：Increase coating layer thickness reaches the meter upper deviation in the middle part of coating, and coating
The thickness that lower edges then reduce coating reaches the lower deviation of design.
The Vehicle Processing that critical size inside wheel chamber casing is carried out after the machining of remaining surplus is to select sprayable shape
The cutter row processing of cutting object, ensures that coating state is constant.
In the method for the present invention, the processing route arrangement of wheel chamber casing, by smart car process by internal significant dimensions, be related to
The size subsequently assembled stays 0.3mm~0.5mm surpluses, rather than whole Vehicle Processings are in place, carried out again after process to be sprayed
The processing of remaining surplus, so can effectively offset the impact of blast in spraying process, spraying process to housing.
Before spraying process inner mold face or assembling T-slot in accompanying elastomeric material filler is installed, spraying process into
Row application.Its benefit one is can to offset spraying, blast work step to the impact force of part；The surplus in two pairs of guarantee type faces is equal
It is even, control the deflection of part under end-state.
The processing dimension of coating is adjusted in car coating procedure.The effect of casing coating is turned inside mating parts
Blades carry out the rotation of high speed, and high temperature resistant, the wearability of wheel chamber casing are improved in the case of high speed rotation, high pressure.Cause
The thickness of this coating is the important parameter of an influence engine performance, if coating is thicker, since coating material is soft, is held
Easily there is part, edge comes off, the situation of chip off-falling.And coating is relatively thin, the on-the-spot meeting of coating shedding significantly reduces but casing shell
Body high temperature resistant, wear-resisting degree can also decrease, and influence the performance of engine.Therefore designer is according to experiment repeatedly
Contrast provides metastable coating layer thickness after comprehensive analysis.And substantial amounts of actual production, test run verification in we
It was found that the centre position of coating is to undertake wheel chamber casing high temperature resistant, wear-resisting main portions, and the effect that upper and lower ends then undertake compared with
It is few.And since upper and lower side is the edge of coating, so local coatings chip off-falling, the phenomenon to come off are then particularly evident.Therefore, in car
It is processed when grinding coating using arc-shaped structure, in the case where fully meeting design requirement, foundation designs the painting provided
Layer tolerance is processed.The middle part increase coating layer thickness of coating is close to the design upper deviation, and the lower edges of coating then reduce painting
Lower deviation of the thickness of layer close to design.It so ensure that the performance of engine, while improve the use longevity of casing coating
Life.
The Vehicle Processing of critical size inside wheel chamber casing is carried out after coating machines, due to cated presence, institute
Cutting fluid cannot be poured as usual with us to be processed, thus we selected on cutter can be with spray form cutting object
Instrument is processed, and since cutting output is smaller, so not influencing the processing of part, and does not interfere with coating state, final to ensure
The processing quality of part.
As shown in Figure 1, 2, for the present embodiment by taking the high pressure rear housing of certain model as an example, inside is sprayed with nickel aluminium high-temperaure coating,
It is used to fan-shaped section be installed equipped with T-slot at the same time, and is engaged with 6-9 grades of rotor blades, as shown in Figure 4.
The high pressure rear housing inside parts T-slot structure is relative complex, and dimensional accuracy is higher, meeting after part deformation amount is larger
There are Assembly Interference, and the larger situation of assembling resistance, influences efficiency of assembling.Coating layer thickness is 1mm, coating layer thickness tolerance 0.2mm.
It is to be coated in smart car process for thering is the size of assembling demand is unilateral to stay 0.3mm surpluses using the method for the present invention
It is processed after machining, ensures part machining state.
In spraying process, assembled in T-slot, using elastomeric material filler, to ensure the spraying state of part.
As shown in figure 3, in the processing dimension of car mill coating procedure adjustment coating, by coating Vehicle Processing structure in the arc-shaped,
Coating centre position, which is processed into, applies thickness point (by the upper deviation processing of design requirement), ensures the high temperature resistant, wear-resisting of wheel chamber casing
Program.The thin point (being processed by the lower deviation of design requirement) of coating is processed into the upper and lower end face of coating, ensures the adhesive force of coating,
Avoid coating local shedding, chip off-falling.
The Vehicle Processing of significant dimensions, critical size inside wheel chamber casing is carried out after coating machines, due to there is coating
Presence, all we cannot pour cutting fluid as usual and are processed, therefore we have selected and can spray on cutter
The instrument of shape cutting object is processed, and since cutting output is smaller, so not influencing the processing of part, and does not interfere with painting stratiform
State, finally ensure that the processing quality of part.
