Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, " upper and lower, left and right " that the noun of locality of use typically refers in the structure shown in Fig. 1-Fig. 3 as " upper and lower, left and right ".
The utility model provides a kind of gear chamber foundry goods of motor, wherein, described gear chamber foundry goods is panel-like member and has through fuel pump mounting hole 1, be reserved with hole processing region around fuel pump mounting hole 1, this hole processing region can process mounting hole with the fuel pump of Matching installation dimension at diverse location.
Normally, in order to install fuel pump in gear chamber, need around fuel pump mounting hole 1, arrange the threaded mounting hole matched, the mold of traditional gear chamber foundry goods arranges dissimilar threaded mounting hole according to dissimilar fuel pump, namely needs the fuel pump for each type to make corresponding mold.In the utility model, the foundry goods only reserved hole processing position of formation, therefore can use same mold cast gear room foundry goods, and the position reprocessing tapped hole then needed, can mate different fuel pump types.Therefore, the technical solution of the utility model has larger advantage in cost control.
Further, described hole processing region is formed as boss 2 to be processed.As shown in Figure 1-Figure 3, boss 2 to be processed is arranged around fuel pump mounting hole 1, namely can process the tapped hole of corresponding internal diameter in the arbitrary position around fuel pump mounting hole 1.Owing to defining boss 2 to be processed, relatively increase the thickness in described hole processing region, therefore can improve the intensity in this region, the impact of bearing when can resist thread mill drilling better; In addition, when thread mill drilling, grinding process can be carried out to the surface of foundry goods, be convenient to pass machining.
Further, the outwardly formation curved edge 21 in ground, edge section of boss 2 to be processed is to mark the operative position of tapped hole.A certain specific gear chamber structure can correspond to several main fuel pump, therefore the pass arrangement mode of this several main Types can be marked in described hole processing region, such as, above-described curved edge 21 can be formed to mark circular mounting point.The global shape of boss 2 to be processed can be formed as asymmetrical, staff can make multiple plates that can overlap with the shape of boss 2 to be processed, and each plate is formed respectively the tapped hole arrangement mode corresponding to different fuel pump, plate therefore can be used to assist the hole processing position determined on boss 2 to be processed.
