Description
Technical field
The utility model relates to a kind of high complexity piston.
Background technique
Piston is parts reciprocating in Motor Engine Cylinder body.Therefore the machining accuracy index of piston has great importance.It is poor to there is precision in traditional servopiston, and intensity is lower, the defect that working life is lower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of precision higher, intensity is higher, the high complexity piston that working life is longer.
The purpose of this utility model is achieved in that
A kind of high complexity piston, it comprises the piston rod body of lateral arrangement, the left side of piston rod body offers through hole to center, right side, the left end cylindrical of described piston rod body is provided with circular groove, right section of cylindrical of described piston rod body is provided with spline, it is characterized in that described through hole comprises tapped hole section from left to right successively, first straight hole section, arcuate socket section, second straight hole section and oil through, the diameter of described tapped hole section is 38mm, the pitch of tapped hole section is 1 inch of 12 tooth, the diameter of described first straight hole section is greater than the diameter of the second straight hole section, excessive by arcuate socket section between described first straight hole section and the second straight hole section.
Carburizing depth 1.5 ~ the 2.12mm of whole piston rod body.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts special via design, and wherein tapped hole section can be connected and fixed preferably, excessive by arcuate socket section between the first straight hole section and the second straight hole section, this place can be eliminated stress concentrated.Therefore to have precision higher for the utility model high complexity piston, and intensity is higher, the advantage that working life is longer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
Through hole 1, tapped hole section 1.1, first straight hole section 1.2, arcuate socket section 1.3, second straight hole section 1.4, oil through 1.5
Circular groove 2
Spline 3.
Embodiment
See Fig. 1, the high complexity piston of the one that the utility model relates to, it comprises the piston rod body of lateral arrangement, the left side of piston rod body offers through hole 1 to center, right side, the left end cylindrical of described piston rod body is provided with circular groove 2, circular groove 2 is for installing seal ring, right section of cylindrical of described piston rod body is provided with spline 3, described through hole 1 comprises tapped hole section 1.1 from left to right successively, first straight hole section 1.2, arcuate socket section 1.3, second straight hole section 1.4 and oil through 1.5, the diameter of described tapped hole section 1.1 is 38mm, the pitch of tapped hole section 1.1 is 1 inch of 12 tooth, the diameter of described first straight hole section 1.2 is greater than the diameter of the second straight hole section 1.4, excessive by arcuate socket section 1.3 between described first straight hole section 1.2 and the second straight hole section 1.4, this place can be eliminated stress concentrated.
Carburizing depth 1.5 ~ the 2.12mm of whole piston rod body.
