Abstract
The utility model discloses a valve spring upper base for an engine. The valve spring upper base is characterized in that a large boss is arranged in the middle of the outer diameter of a circular base body; a small boss which is shrunken gradually is arranged below the large boss; and an air exhaust/inlet hole is formed in the middle of the circular base body. By the arrangement, the valve spring upper base is made of special steel, and is subjected to cold extrusion forming, so that the conical degree of the spring upper base is ensured better. The valve spring upper base meets using requirements for geometrical shapes and abrasive resistance.
Description
Technical field
The utility model relates to a kind of engine component, is that a kind of motor is used the valve spring seat of honour specifically.
Background technique
Motor is used for connecting valve spring and valve with the valve spring seat of honour, and its performance directly influences the quality of whole motor.Motor adopted external import in the past with the valve spring seat of honour, but external import has a lot of inconvenience: the one, and it is untimely to supply, and the 2nd, quality problems difficult coordination, particularly tapering problem, the 3rd, cost an arm and a leg.
Summary of the invention
The purpose of the utility model provides a kind of motor and uses the valve spring seat of honour.
To achieve these goals; The utility model is provided with big boss in the intermediate portion of circular seat body diameter; Below big boss, be provided with the small boss that dwindles step by step, row's inlet hole is located at the intermediate portion of circular pedestal, and the lower inner surface of said row's inlet hole is the hole of band inner conical surface.
Through above setting, the utility model adopts special steel to do, and adopts cold extrusion shapedly, has better guaranteed the tapering at the spring seat of honour.Adopt the atmosphere protection multipurpose stove that valve spring seat of honour surface high frequency is quenched, better guaranteed the wear resistance at the spring seat of honour.No matter the utility model is from geometrical shape or wear resistance, all reaches usage requirement.
Description of drawings
Combine accompanying drawing that the utility model is further specified at present.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, circular pedestal, 2, big boss, 3, small boss, 4, row's inlet hole.
Embodiment
As shown in Figure 1; The utility model is provided with big boss 2 in the intermediate portion of circular pedestal 1 external diameter; Below big boss 2, be provided with the small boss 3 that dwindles step by step, row's inlet hole 4 is located at the intermediate portion of circular pedestal 1, and the lower inner surface of said row's inlet hole 4 is the hole of band inner conical surface.Through above setting, the utility model unique texture and inherent technical order make the whole motor match mechanism can good operation, and the special tapering of row's inlet hole 4 internal surfaces has guaranteed and the good fit of valve collet, has effectively guaranteed coupling mechanism force.Surface high frequency is quenched when having guaranteed the utility model motion can self be wear-resisting, and even to the valve collet grinding.
