Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific drawings.

[0020] Such as figure 1 , figure 2 with image 3 As shown, the high-precision rotor for automobile VVT ​​of the present invention is a component in the automobile VVT ​​and is used to cooperate with the stator. The main structure of the rotor includes a cylinder 1 with a structure of a through hole 2, and lines are provided on the through hole 2. On the outer wall of the cylinder 1, there are first protruding ribs 3, second ribs 4 and third ribs 5 protruding outwards, wherein the arc width of the first ribs 3 and the second ribs 4 Similarly, the arc width of the third rib 5 is greater than that of the first rib 3, and axial grooves are arranged on the arc surfaces of the first rib 3, the second rib 4 and the third rib 5, respectively The first groove 31 , the second groove 41 and the third groove 51 . The cylinders 1 on both sides of the first rib 3 are provided with a f...

Abstract

The invention discloses a high-precision rotor for automobile VVT and a manufacturing method of the high-precision rotor. The rotor comprises a cylindrical body with a structure of a through hole, wherein a first flange, a second flange and a third flange, which extend outwards, are arranged on the outer side wall of the cylindrical body; the width of the cambered surface of the first flange is equal to that of the cambered surface of the second flange; the width of the cambered surface of the third flange is larger than that of the cambered surface of the first flange; axial notches are respectively formed in the cambered surface of the first flange, the cambered surface of the second flange and the cambered surface of the third flange; holes which communicate with the through hole are separately formed in the cylindrical body, on two sides of the first flange, two sides of the second flange, and two sides of the third flange; a flange through hole is formed in the first flange; and an axial groove which extends downwards is formed in the flange through hole. The rotor disclosed by the invention is high in precision, simple in structure, stable in performance, and convenient to mount and use. In manufacturing, before a product is completely burnt to be hard, a plurality of side holes and crossed holes are formed through primary machining; after finishing is performed on the product, a plurality of high-precision holes are formed through finish machining; and the economy and the high efficiency of drilling are guaranteed by utilizing a special characteristic of incomplete sintering of powder metallurgy.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a high-precision rotor for automobile VVT ​​and a preparation method thereof. Background technique [0002] The VVT ​​rotor is a component of the variable valve, which is used to adjust the intake air volume of the valve at different speeds, improve combustion efficiency, increase engine power and reduce exhaust emissions. Conventional rotors have complex shapes, low precision, difficult preparations by traditional processing methods, and bad ratios, so they cannot meet the needs of use. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the invention is to provide a high-precision rotor for automotive VVT, which has the advantages of high precision, simple structure, and easy manufacture, and meets the needs of use. Another object of the present invention is to provide a method for pr...
