Abstract
The utility model discloses a tappet synthesized by different metal materials. The tappet is structurally characterized in that a guide bar is in a hollow barrel shape, and the bottom end of the guide bar is provided with a spherical raised head. The center of an insert is a concave spherical working face, and the guide bar and the concave spherical working face of the insert are subjected to friction welding into a whole to form the tappet. A through hole is formed at the lower part of the guide bar, and the through hole has the effect of discharging redundant lubricating oil, namely an oil spilling (hole) effect is realized. The spherical raised head at the bottom end of the guide bar is in good contact with the concave spherical cambered surface at the center of the insert. According to the tappet which is formed by carrying out friction welding on the two different metal materials, the weight of a transmission chain of a valve actuating mechanism can be reduced, and the working reliability of the tappet is further improved. Meanwhile, the manufacturing and machining cost can be effectively reduced, and the production efficiency can be improved.
Description
Technical field
The utility model belongs to gas engine part, is specifically related to the tappet in distribution device in a kind of diesel engine.
Background technique
In working process of diesel engine, the switching of valve by camshaft transmission complete.As the driving component-tappet of distribution device, the reliability of its work is vital.The material of general this valve tappet is all the cast iron integral type, then operative end surface is carried out cold shock.Such tappet, manufacturing process complexity and processing cost are also higher.Key is in movement process, and is usually excessive and easily cracked due to stress.For this technological deficiency, the utility model proposes the tappet of split material formula, can effectively address the aforementioned drawbacks.
Summary of the invention
The purpose of this utility model has been to provide a kind of tappet that is integrated by two kinds of different metal materials, can effectively reduce the weight of gas distribution structure, improves the reliability of distribution device.
Below in conjunction with accompanying drawing, the technical solution of the utility model is explained: the tappet that different metal material is synthetic, its technological scheme is that guide rod is that open circles is barrel-shaped, the guide rod bottom is spherical plush copper, the bottom of guide rod is provided with through hole, the center of inserting is interior concave ball shape working surface, and guide rod is integrated and becomes tappet with the concave ball shape working surface friction welding of inserting.Be provided with through hole below guide rod, its effect is unnecessary lubricant oil can be emitted, and has the effect in oil spilling (hole).The spherical plush copper of guide rod bottom forms good contacting with the indent spherical arc at the center of inserting.Two kinds of different metal materials refer to: guide rod adopts carbon steel material 20 or 20Cr; The concave ball shape cambered surface of inserting adopts alloy cast iron material.
The working principle of friction welding: (to be welded) surface of two thermoplasticity fabricated metalss is in contact with one another rotation, makes it that frictional heat occur, and this moment, the mating face melted by heat, can become an integral body under certain pressure.
The beneficial effect of characteristics of the present utility model and generation is, by two kinds of different metal materials, by friction welding, is integrated and becomes tappet, can effectively reduce the Transmitted chains weight of distribution device, and then improves the functional reliability of tappet.Can effectively reduce simultaneously and make processing cost and enhance productivity.
Description of drawings
Shown in accompanying drawing 1 be the utility model structure and principle simplified schematic diagram.
Embodiment
Structure of the present utility model is further described by specific embodiment below in conjunction with accompanying drawing 1.The tappet that different metal material is synthetic, its structure is that guide rod 1 is barrel-shaped for open circles, the guide rod bottom is spherical plush copper, the bottom of guide rod is provided with through hole 2,3 centers of inserting are interior concave ball shape working surface, guide rod is integrated with the concave ball shape working surface friction welding of inserting, and inserts and is connected together and becomes tappet with camshaft.The diameter of guide rod is φ 26mm; The diameter of through hole is φ 3mm; The diameter of the concave ball shape cambered surface of inserting is identical with the spherical plush copper of guide rod.Guide rod adopts carbon steel material 20 or 20Cr cold hobbing to form, and the concave ball shape cambered surface of inserting adopts alloy cast iron material.
Friction welding is a kind of technique of welding, and the tappet of this structure, its guide rod are partly by the cold hobbing rapid shaping, so its manufacture cost is lower.
