Abstract
The utility model relates to a flyweight support used for a speed controller, which is mainly applicable to a diesel engine fuel injection system and pertains to a core component of the diesel engine fuel injection system, the flyweight support comprises a T-shaped support body, and is characterized in that the support body consists of a flat plate and a column provided with an inner hole, wherein the column is positioned at the center of the flat plate; a convex rib which is connected with the column into a whole is arranged in the inner hole of the column; and the whole T-shaped support body is integrally molded by cold extrusion. The flyweight support has reasonable structure design, indeed meets the requirement on an integral structure which can not be disassembled, and leads the installed diesel engine fuel injection system to be used safely and reliably; and simultaneously, the flyweight support has low cost and long service life.
Description
Technical field
The utility model relates to a kind of support, particularly a kind of flying hammer bracket that is used for speed regulator, and it mainly is applicable in the diesel fuel injection system, belongs to the core component in the diesel fuel injection system.
Background technique
Like product of the prior art, by the rack body of two support shafts and a polymorphic structure through the assembling of screw thread pretension and implement vacuum brazing and reach fixing purpose.Because above structure is not integrated overall structure, so in use there is following shortcoming in it: can not satisfy Equipment Requirement with its reliability of diesel engine after the above product installation, occurring the flying hammer bracket body easily separates with support shaft, the flyball disequilibrium, the consequence that causes fuel injection system even whole diesel engine to be scrapped occurs; Simultaneously, processed complex, cost height.On manufacturing process, prior art adopts thermal forging technology usually or uses the powder metallurgy manufacturing, is difficult to put in place with the thermal forging technology size, and then intensity and stability all can not get guaranteeing with powder metallurgy.
The model utility content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of reasonable in design is provided, and is safe and reliable, the measured flying hammer bracket that is used for speed regulator of matter.
The technical scheme in the invention for solving the above technical problem is: this flying hammer bracket that is used for speed regulator comprises the stake body of T shape, it is characterized in that: described stake body is made up of with the cylinder that has endoporus dull and stereotyped, described cylinder is positioned at dull and stereotyped center, the endoporus of cylinder is provided with the convex tendon that fuses with cylinder, and whole T shape stake body is one-body molded by cold hobbing.
Convex tendon described in the utility model has three, and these three convex tendons are evenly distributed on the inner hole wall of cylinder.
The utility model compared with prior art has the following advantages and effect: reasonable in design, and whole T shape stake body is one-body molded by cold hobbing; The endoporus of three convex tendons and cylinder has guaranteed not processability that finished product requires and the reliability that has kept metal to extend naturally; Diesel fuel injection system behind installation the utility model is safe and reliable, and quality is good; Simultaneously, cost is low, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model (part is analysed and observe).
Fig. 2 is the structural representation of looking up of Fig. 1.
Fig. 3 is the plan structure schematic representation of Fig. 1.
Embodiment
Referring to Fig. 1-Fig. 3, the utility model is the stake body 1 of a T shape, this stake body 1 is formed with the cylinder 3 that has endoporus 31 by dull and stereotyped 2, described cylinder 3 is positioned at the center of dull and stereotyped 2 length directions, the endoporus 31 of cylinder 3 is provided with the convex tendon 32 that fuses with cylinder 3, and whole T shape stake body 1 is one-body molded by cold hobbing.Described convex tendon 32 has three, and these three convex tendons 32 are evenly distributed on the inner hole wall 33 of cylinder 3.
The utility model can put a lot of sizes of product in place by cold-extrusion technology, has reduced the convex tendon 32 that fuses with cylinder 3 on the process time and the expense in later stage, particularly inner hole wall 33 to a great extent, this be machining can't realize.And the endoporus 31 of three convex tendons 32 of the present utility model and cylinder 3 has guaranteed not processability that finished product requires and the reliability that has kept metal to extend naturally.
In addition, need to prove, specific embodiment described in this specification, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
