Abstract
The utility model discloses a turbine with a petal-shaped shaft head belonging to turbines, in particular to a turbine for automobile superchargers.The turbine is molded by centrifugal casting.The front of the mandrel is equipped with a shaft head. The mandrel and the blades are integrally formed into one piece.The rear end of the mandrel is welded with a flange.The turbine is characterized in that the mandrel is conical bench-shaped and the blades are centrosymmetric with the shaft head as the center.The blades are rotatably connected with the mandrel.The upper portion of the blade is bent to be curved surface and the lower portion thereof is straight.The upper portion and the lower portion of the blade are in a smooth connection with each other.The shaft head is cylindrical and the outer rim thereof is equipped with antiskid grooves.The antiskid grooves connected end to end in sequence are petal-shaped of the same shape.The center of the shaft head is equipped with a hemispherical top hole.The centers of the top hole, the shaft head, the mandrel and the welded flange lie in the same axis.The turbine has the advantages that the petal-shaped shaft head can be directly introduced into the clamp to be positioned automatically during the positioning of the processing clamp of an automatic lathe, thereby improving the processing efficiency.During the shaft rotation of the welding, the hemispherical top hole bearing great axial fastening force is maintained to be center-aligned, thereby ensuring the product quality.Meanwhile, the processing is convenient and the cost is lowered.
Description
Technical field
The utility model belongs to turbine, relates in particular to the automobile turbocharger turbine.
Background technique
Turbine is the turbosupercharger core component, and turbine is connected it by friction-welding machine with rotating shaft, and the working environment of turbine is extremely abominable, and it is bearing the erosion of high temperature and high pressure all the time during operation, so it is to be formed by the alloy material casting.Current, the turbine of use is to be combined by axle and blade, and the axle front end establishes cylindrical or square column type, hexagon spindle nose, clamping location when being used to process.The taper apical pore is established at the spindle nose center, and mandrels backend is established weld flange, is connected with the rotating shaft friction welding.Its defective is, automatic lathe adds man-hour, and cylindrical spindle nose skids easily, is difficult for clamping processing, and when square column type, hexagon spindle nose clamping location, needs to rotate than wide-angle, can locate, and work efficiency is low; Produce huge axial force during friction welding, taper apical pore bearing capacity ability is low, easy to crack, and product percent of pass is low, the processing cost height.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of petal spindle nose turbine, and the clamping location is convenient, increases the spindle nose bearing capacity, improves work efficiency, reduces cost.
Petal spindle nose turbine is by the centrifugal casting moulding, axle and vane group are integrated, the axle front end is established spindle nose, mandrels backend is established weld flange, weld flange is connected with the rotating shaft friction welding, be characterized in that described axle is a truncated cone, blade is that the center symmetry is curled up and is connected on the axle with the spindle nose center; The blade upper bend becomes cambered surface, and the bottom is straight, and both connect gently; Described spindle nose is cylindrical, the outer rim chute of setting up defences, be that shape is identical, end-to-end petal; The hemisphere apical pore is established at the spindle nose center, and the center of apical pore and spindle nose, axle and weld flange together on an axis.
The utility model further improves, and described anti-slip tank is 12, is similar to 12 petals, 15 ° of orientation angles.
Compared with prior art, advantage is: when the automatic lathe processing and loading clamp was located, the petal-shaped spindle nose can directly import anchor clamps and locate automatically, and work efficiency improves greatly; During the welding rotating shaft, the hemisphere apical pore can sustain huge axial pressure, and the center that remains aligns, and has both protected quality of product, and convenient again processing cuts down finished cost.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
Fig. 1 is a petal spindle nose turbine structure schematic representation.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Embodiment
By Fig. 1, Fig. 2, Fig. 3 as can be seen, the petal spindle nose turbine that centrifugal casting forms, front end is established spindle nose 1 on the truncated cone central shaft 3, and weld flange 5 is established in the rear end, and blade 4 is that the center symmetry is curled up and is connected on the axle 3 with the spindle nose center; The blade upper bend becomes cambered surface, and the bottom is straight, and the upper and lower part is connected in one gently.
As seen from Figure 2, spindle nose 1 is cylindrical, and outer rim is established 12 anti-slip tanks 6, is similar to 12 petals, and petal shape is identical to join end to end.
By Fig. 1, Fig. 2 as can be seen, hemisphere apical pore 2 is established at spindle nose 1 center, and apical pore center and axle are together on an axis.
By Fig. 1, Fig. 3 as can be seen, weld flange 5 is located in the mandrels backend in the heart, and rotating shaft (among the figure mark) links together with the weld flange friction welding.
