Abstract
The utility model belongs to the field of supercharging devices, and particularly relates to a spray nozzle of a supercharging device capable of changing the spray nozzle. The spray nozzle comprises an annular chassis and a plurality of blades, the end face of the chassis is provided with a plurality of through holes equivalent to the number of the blades, the through holes are uniformly distributed along the annular chassis, the through holes are arranged on a circle of concentric with the annular chassis, a boss is arranged on the bottom of each blade, and the boss is fixedly arranged in each through hole. The spray nozzle has the advantages that the chassis and each blade are connected and positioned through a rectangular interface, besides a self-positioning function, the spray nozzle is also provided with a self-locking function, so that the occurrence of rotation of the blades on the chassis during welding is effectively prevented, the distribution of the blades is enabled to be corresponded to that of holes in a guide disc, and the blades are enabled to smoothly insert into a guide disc ring. Compared with the processing method of a five-axis machining center, the method has a fast speed, is low in cost, and solves the problems of easy inclination and deformation of spray nozzle blades in a casting process at the same time.
Description
Technical field
The utility model belongs to the pressurized machine field, is a kind of variable-nozzle pressurized machine nozzle specifically.
Background technique
Traditional turbosupercharger is generally matched nozzle ring according to the operating mode of peak torque.Therefore, during the pressurized machine high speed operation, often need adopt and open bleed valve, release a part of waste gas to prevent the pressurized machine hypervelocity, waste a part of exhaust energy when its shortcoming is high speed and the Efficiency Decreasing of pressurized machine.The turbosupercharger of variable-nozzle can address the above problem effectively, and it can guarantee that not only motor when low speed, has higher boost pressure, thereby higher torque is arranged; Can also guarantee that near motor boost pressure rated point is unlikely too high, to avoid the hypervelocity of the too high mechanical load of motor and turbosupercharger.
In the prior art, if adopt the nozzle of direct casting technique processing pressurized machine, because the Action of Gravity Field of blade self is so that the contacting part branch of blade and mounting disc deforms, the angle out of plumb of blade and mounting disc causes and blade can't be inserted in the guide ring.Therefore, generally adopt in the world at present five axle machining centers, process the pressurized machine nozzle in the mode of cutting, caused like this process time of pressurized machine nozzle and expense all higher, so that user's use and replacement cost significantly promote.
Summary of the invention
The utility model has the advantages that in the above-mentioned technology, directly cast existing shortcoming in processing and the five axle Cutter Body Processing with Machining Center, a kind of variable-nozzle pressurized machine nozzle has been proposed, the utility model is owing to adopt the chassis and the method for blade combination obtains the finished product nozzle, but can make up flexibly for the similar nozzle of different model blade or chassis.Be beneficial to the exploitation of new product.
The utility model provides following technological scheme:
The nozzle of variable-nozzle pressurized machine, it comprises chassis and some blades of annular, be provided with some through holes that equate with blade quantity on the end face on chassis, through hole evenly arranges along annular chassis, through hole be arranged on the concentric circle of annular chassis on, the blade bottom is provided with boss, and described boss is fixed in the through hole.
Described through hole is rectangular through-hole, and described boss is rectangular boss.
Between described chassis and the blade by being welded and fixed.
Be connected the location by the rectangle interface between the chassis that the utility model has the advantages that and the blade, except being arranged, self-align effect also has the effect of self-locking, effectively when having prevented welding blade rotate on the chassis, the distribution in hole is corresponding on the distribution that makes blade and the godet, thereby can make blade can insert smoothly in the godet ring, with respect to the method for five axle Cutter Body Processing with Machining Center, the method speed is fast, price is low, has solved simultaneously the problem that nozzle vane tilts and is out of shape easily in casting process.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation on chassis;
Fig. 3 is the structural representation of blade.
Embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, the nozzle of variable-nozzle pressurized machine, it comprises chassis 1 and some blades 3 of annular, is provided with some through holes 2 that equate with blade 3 quantity on the end face on chassis 1, through hole 2 evenly arranges along annular chassis, through hole 2 be arranged on the concentric circle of annular chassis on, blade 3 bottoms are provided with boss 4, described boss 4 is fixed in the through hole 2, wherein, through hole 2 is rectangular through-hole, and boss 4 is rectangular boss, between chassis 1 and the blade 3 by being welded and fixed.
The nozzle processing method of variable-nozzle pressurized machine, its step is as follows:
A, the method that dewaxes by the paraffin mould cast out two independently blanks: two blanks are respectively chassis and blade.Blade bottom end has a rectangular boss;
B, the domain blank that obtains in a step is gone out equally distributed rectangular hole by the line cutting process.
C, two initial blanks that obtain in a step and the b step are carried out respectively machining, surface treatment;
D, with the chassis that processes with blade welds and the parts welding, obtain the finished product nozzle.
Method by casting in a step obtains the chassis, and the blade with the rectangular boss.The rectangular boss size of the blade bottom end that casts out in the rectangular hole that cuts out by line in the b step and a step is corresponding.The boss that why casts out and the hole that cuts out are rectangular, reason is because rectangular square interface also has the effect of self-locking except self-align effect is arranged, effectively when having prevented welding blade rotate on the chassis, the distribution in hole is corresponding on the distribution that makes blade and the godet, thereby blade can be inserted in the godet ring smoothly.With respect to the method for five axle Cutter Body Processing with Machining Center, the method speed is fast, price is low, has solved simultaneously the problem that nozzle vane tilts and is out of shape easily in casting process.
Surface treatment in the described c step comprises the external cutting of mounting disc.External cutting makes the external diameter of mounting disc reach needed installation dimension.
Soldering is adopted in welding in the described d step.Heating temperature is lower, and joint is smooth smooth, and tissue and mechanical property variation are little, is out of shape littlely, and workpiece size is accurate, and brazing equipment is simple, and the investment of production expense is few.
In the d step, obtain the finished product nozzle and need to install adjustable lever in mounting disc.
The utility model has the advantages that the production and processing method that has changed conventional turbine pressurized machine nozzle, improved widely manufacturing efficiency, reduced cost of production.
