Abstract
The utility model discloses a special top cup of diesel oil engine for a digging machine, aiming at providing a special top cup of diesel oil engine for a digging machine which has material saving ability, reasonable structure, easy manufacture, low manufacturing cost, high fatigue resistance and long service life. The special top cup of diesel oil engine for a digging machine is a basin-shaped shelly entirety with even thickness, comprising a flange edge (1) and a boss (2). The flange edge (1) and the boss (2) are smoothly transited and connected by frontal and inverse two arcs (R1), (R2).
Description
Technical field:
The utility model relates to the architecture advances of excavator with parts and components of diesel engine.
Background technique:
The diesel engine of excavator must be installed a special end cap, connects main oil pump.Existing end cap adopts Plate Steel turning to process, and is the right angle between end cap flange edge and the boss and is connected, and stress is concentrated, and fatigue resistance is low, and lack working life, and waste of material is big, the manufacture cost height.
The model utility content:
Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, and a kind of saving material is provided, and is rational in infrastructure, easy to manufacture, reduces manufacture cost, fatigue resistance height, the excavator that the increases the service life special-purpose end cap of diesel engine.
The utility model adopts following technological scheme to solve the problems of the technologies described above, and the utility model is the basin shape shelly integral body of an equal thickness, comprises flange edge and boss, is connected smoothly by positive and negative two circular arcs between flange edge and the boss.
As further improvement of the utility model, offer positioning spigot on the described flange edge; Have the installation screw on the boss; Have mounting hole on the flange edge.
The utility model is owing to be the basin shape shelly integral body of an equal thickness, and adopts circular arc to be connected smoothly between flange edge and the boss, reduced difficulty of processing.Circular curve is mild, has overcome the stress concentration phenomenon, improves fatigue resistance, thereby increases the service life.In addition, structure of the present utility model can be eliminated the drawing process that bowl adds man-hour, has only the action of the shape of pressure, has reduced the punch process difficulty, has reduced the requirement of processing technology to mould.The utlity model has the feature of " shell ", structure is more reasonable, saves material, has reduced manufacture cost.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
Shown in accompanying drawing 1,2, the utility model is the basin shape shelly integral body of an equal thickness, comprises flange edge 1 and boss 2.Between flange edge 1 and the boss 2 by positive and negative two circular arc R
1, R
2Seamlessly transit.Offer positioning spigot 3 on the flange edge 1, have on the boss 2 screw 4 is installed, have mounting hole 5 on the flange edge 1.
Present embodiment adopts hot pressing punch forming of 16mm steel plate.
Claims (4)
1, a kind of excavator is characterized in that with the special-purpose end cap of diesel engine it is the basin shape shelly integral body of an equal thickness, comprises flange edge (1) and boss (2), between flange edge (1) and the boss (2) by positive and negative two circular arc (R
1), (R
2) be connected smoothly.
2, excavator according to claim 1 is characterized in that having on the described flange edge (1) positioning spigot (3) with the special-purpose end cap of diesel engine.
3, excavator according to claim 2 is characterized in that having on the described boss (2) installation screw (4) with the special-purpose end cap of diesel engine.
4, according to claim 1 or the 2 or 3 described excavators special-purpose end cap of diesel engine, it is characterized in that having on the described flange edge (1) mounting hole (5).
