Abstract
The invention discloses a precise flange of an energy internal combustion engine. The precise flange of the energy internal combustion engine comprises an annular flange body. Two lugs and two arc-shaped bosses are formed on the outer wall of the flange body by means of integral forging, and the bosses are positioned on two sides of each lug; the lugs are positioned in the middle of the outer wall of the flange body, and the bosses are positioned at the bottom of the outer wall of the flange body; chamfers are arranged at joints of the bosses and the outer wall of the flange body. The precise flange has the advantages that the precise flange is simple in structure, reasonable in design, convenient to operate, high in precision and long in service life and does not need to be frequently replaced, the internal combustion engine can be in close fit with other equipment, good sealing effects can be realized, the production efficiency can be improved, and the cost can be saved.
Description
Technical field
The present invention relates to internal combustion engine fittings technical field, especially a kind of accurate energy internal-combustion engine flange.
Background technique
Internal-combustion engine is a kind of dynamic power machine, and it is by making fuel burn at machine intimate, and the heat energy of being released directly is converted to the heat engine of power.Sensu lato internal-combustion engine not only comprises stroke piston combustion engine, rotary engine and free piston engine, also comprise the gas turbine of rotary vane type, jet engine etc., but usually said internal-combustion engine refers to internal-combustion piston engine.Internal-combustion piston engine is the most general with reciprocating piston type.Internal-combustion piston engine, by fuel and air mixing, burns in its cylinder combustion, and the heat energy discharged makes the combustion gas producing High Temperature High Pressure in cylinder.Combustion gas is expanded and is promoted piston work done, then mechanical work is exported by connecting rod or other mechanisms, drives follower work.Flange is an indispensable vitals in internal-combustion engine, in order to connect internal-combustion engine and other equipment.Traditional flange arrangement is complicated, and after connecting, sealability is undesirable, and working life is short simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, the accurate energy internal-combustion engine flange of good seal performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of accurate energy internal-combustion engine flange, comprises the flange body of ring-type, and flange body outer wall one forging molding has the boss of two lugs and two arcs, and boss is positioned at the both sides of lug; Described lug is positioned in the middle part of flange body outer wall, and boss is positioned at bottom flange body outer wall;
Described flange body inwall comprises the first straightway inwall, the second straightway inwall, the 3rd straightway inwall, the 4th straightway inwall and the 5th straightway inwall that distribute successively from top to bottom, 3rd straightway inwall is connected to the second straightway inwall by the first arc inwall, is connected with the second arc inwall between the 3rd straightway inwall and the 4th straightway inwall; Horizontal segment inwall is connected with between described second straightway inwall and the first arc inwall;
Described lug and flange body outer wall joint are provided with chamfering.
Further, the diameter of described described the second straightway inwall, the 4th straightway inwall, the 3rd straightway inwall, the first straightway inwall and the 5th straightway inwall becomes large successively.
Further, described boss upper surface and flange body outer wall joint are provided with chamfering, and boss lower surface and flange body lower surface are in same level.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, easy to operate, flange body outer wall one forging molding has two lugs, compares traditional welding lug, and firmly, more easy to process, reduce error, precision is high; Flange body outer wall one forging molding has the boss of two arcs, and flange body inwall is provided with the inwall of different-diameter, and make internal-combustion engine coordinate closely with other equipment, good sealing effect, long service life, does not need frequent replacing, enhance productivity, cost-saving.
