Abstract
The utility model discloses a tappet lubricating device of a cylinder block of a diesel engine. The device comprises a diesel engine cylinder block, a cylinder block tappet hole arranged in the diesel engine cylinder block, counter bores arranged on the circumference surface at the bottom of the cylinder block tappet hole, and beveled oil holes, the axial lines of which are vertical to the bottom surface of the counter bores, wherein the beveled oil holes are communicated with an oil duct, and the diameters of the counter bores are larger than the diameters of the beveled oil holes; therefore, when the beveled oil holes are processed, a cutter is easy to be located, under uniform stress, and uneasy to be damaged, the processing is convenient, the production efficiency is improved, and the rejection rate is reduced.
Description
Technical field
The utility model relates to a kind of lubricating fitting, relates in particular to the lubricating fitting of a kind of lubricated cylinder of diesel engine tappet bottom surface.
Background technique
Tappet oilhole and oil duct on the cylinder of diesel engine communicate, so that be used for lubricated tappet bottom surface and cam.Because the position of cylinder block tappet oilhole is in cylinder block inside, be difficult for processing, can only tiltedly put in inclined oil hole of air of processing from the cylinder block bottom with drill bit, because of inclined oil hole of air axis and hole end surface out of plumb, so be difficult for the location during drilling, and bit force is inhomogeneous, and the drill bit that very easily fractures causes the waste of cutter.Simultaneously also reduce manufacturing efficiency, improved reject rate.
The model utility content
Technical problem to be solved in the utility model provides a kind of lubricating fitting of the cylinder of diesel engine tappet of being convenient to process.
For solving the problems of the technologies described above, the technical solution of the utility model is: the lubricating fitting of cylinder of diesel engine tappet, comprise cylinder of diesel engine, described cylinder of diesel engine inside is provided with cylinder block tappet hole, bottom, described cylinder block tappet hole circumferential surface is provided with counterbore, described counterbore bottom surface is provided with axis and the vertical inclined oil hole of air in described counterbore bottom surface, and described inclined oil hole of air communicates with oil duct, and the diameter of described counterbore is greater than the diameter of described inclined oil hole of air.
Owing to adopted technique scheme, the lubricating fitting of cylinder of diesel engine tappet, comprise cylinder of diesel engine, described cylinder of diesel engine inside is provided with cylinder block tappet hole, bottom, described cylinder block tappet hole circumferential surface is provided with counterbore, described counterbore bottom surface is provided with axis and the vertical inclined oil hole of air in described counterbore bottom surface, and described inclined oil hole of air communicates with oil duct, and the diameter of described counterbore is greater than the diameter of described inclined oil hole of air; Cutter is located easily when the processing inclined oil hole of air like this, and makes cutter stressed evenly, and not fragile cutter is convenient to processing, has improved manufacturing efficiency, has reduced reject rate.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
As shown in drawings, the lubricating fitting of cylinder of diesel engine tappet, comprise cylinder of diesel engine 5, described cylinder of diesel engine 5 inside are provided with cylinder block tappet hole 3, described cylinder block tappet hole 3 bottom circumferential surfacies are provided with counterbore 1, described counterbore 1 bottom surface is provided with axis and the vertical inclined oil hole of air 2 in described counterbore 1 bottom surface, and described inclined oil hole of air 2 communicates with oil duct 4, and the diameter of described counterbore 1 is greater than the diameter of described inclined oil hole of air 2.
Add stretch to cylinder block tappet hole 3 man-hour earlier from the bottom of cylinder block 5 with milling cutter bottom, the counterbore 1 that diameter of milling is A, be the inclined oil hole of air 2 of B with the vertical counterbore of drill bit bottom plane drill diameter then, must make the diameter B of the diameter A of counterbore 1 greater than inclined oil hole of air 2, the drilling degree of depth is until communicating with oil duct 4.Because the inclined oil hole of air axis is vertical with the counterbore bottom plane, locate easily adding the man-hour cutter like this, and cutter is stressed evenly, not fragile cutter.
Claims (1)
