Abstract
The utility model discloses a diesel engine case cover which comprises a body, wherein a mould assembling surface sealed with an engine body is arranged on the body; mounting holes are formed in the mould assembling surface; transverse reinforcing ribs are arranged on the side surface of the body; at least four mounting steps are arranged on the bottom surface of the body; and die-cast through holes are formed in the mounting steps. The strength of a product is improved by the reinforcing ribs, so that a requirement on the thickness and a requirement on the strength are met; the steps and the through holes in the steps can be die-cast directly by position adjustment of fastening screws; and the diesel engine case cover is connected in a fastening manner by screws and nuts, and is quick and convenient.
Description
Technical field
The utility model relates to the structure member of diesel engine, is specifically related to a kind of diesel engine case lid.
Background technique
The motor case lid is the vitals in the internal-combustion engine, and the strength and stiffness of case lid will directly influence the Performance And Reliability of motor.The intensity of case lid then directly influences the working life of motor, and the rigidity of case lid will directly influence the noise and vibration performance of motor.At present, domestic diesel engine makes the case lid strength and stiffness can not get abundant guarantee in order to satisfy the lightweight requirement of case lid, thereby makes that the engine vibration noise is bigger.To the improving constantly of engine luggine noise testing standard, for reaching the examination criteria needs, should take very big improvement measure to rigidity, the intensity of motor case lid at present country.Particularly the traditional approach of processing diesel engine is pouring technology, if adopt cost extrusion process production lower, that efficient is higher to reduce production costs greatly, adapts to the architecture advances that die casting is produced but need make case lid.
The model utility content
It is a kind of simple in structure, compact, reasonable that the purpose of this utility model is to provide, and weight is light and handy, volume is little, external styling is attractive in appearance, is applicable to the diesel engine case lid that die casting in enormous quantities is produced.
For achieving the above object, the technical solution of the utility model is: the diesel engine case lid, comprise body, described body is provided with the mould assembling face with the engine body sealing, described mould assembling face is provided with mounting hole, the side of described body is provided with horizontal stiffening rib, is provided with at least four installation steps in the bottom surface of body, and described installation step is provided with the through hole of die casting.
When adopting technique scheme, strengthen the intensity of product by reinforcement.So both satisfy the requirement on the thickness, also satisfied the requirement on the intensity.The position of fastening screw is adjusted, but rheo-die-casting goes out the through hole on step and the step, uses screw, nut to be fastenedly connected, and is convenient and swift.
Further, in order to increase the bulk strength of diesel engine case lid, described body side also is provided with stiffening rib longitudinally.
Further, owing to the setting of stiffening rib, improved the intensity of integral side walls greatly, therefore 6mm, the wall thickness of tradition cast are adjusted relatively, and the wall thickness of body is 4mm after improving.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model diesel engine case lid embodiment's structural representation.
Embodiment
As shown in Figure 1, the utility model diesel engine case lid, comprised the mould assembling face 1 with the engine body sealing, offer mounting hole 11 on the mould assembling face, be distributed with horizontal stiffening rib 2 and stiffening rib 21 longitudinally on the side of case lid, have four installation steps 3 at least in the bottom surface of case lid, installation step 3 is provided with the through hole 31 of die casting.
Strengthen the intensity of product by stiffening rib.So both satisfy the requirement on the thickness, also satisfied the requirement on the intensity.The position of fastening screw is adjusted, but rheo-die-casting goes out the through hole 31 on installation step 3 and the installation step 3, uses screw, nut to be fastenedly connected, and is convenient and swift.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
