Abstract
The utility model discloses a straight tube type water pump mounting hole. A diesel engine water pump mounting hole is processed by casting into the water pump mounting hole with a straight tube type structure, which ensures that no sand part can be formed in the water pump mounting hole when the water pump mounting hole is processed by casting, and meanwhile ensures that the thickness of the peripheral wall of the water pump mounting hole is uniform to improve the qualification rate of parts; besides, the strength of the water pump mounting hole is improved, the mounting reliability of a water pump is ensured, and the casting processing difficulty and cost of the water pump mounting hole are reduced.
Description
Technical field
The utility model relates to a kind of mounting hole, particularly is a kind of straight-tube mounting hole that is used to install water pump.
Background technique
As everyone knows, when engine operation, need water pump to drive the coolant flow in the engine-cooling system usually, and, offer enough coolant rates of engine-cooling system and lift according to motor different rotating speed and operating mode.
Diesel pump is installed in the water pump mounting hole in the diesel-engine body 1.Existing water pump mounting hole adopts segmented water pump mounting hole, comprises the first hole section 2, cavity 4, the second hole section 3, and its deficiency is: (a) the water pump mounting hole is when casting, and the coaxality of the first hole section 2 and the second hole section 3 is difficult to be guaranteed; (b): sand removal difficulty in the cavity 4 between the two joint mounting holes, it is prone to generation and adds sand; (c): because the coaxality of cast member segmented mounting hole is relatively poor, the wall thickness of processing back two joint mounting holes has difference, can cause a side thickness to be machined away fully when situation is serious, causes part to scrap.
The model utility content
The purpose of the utility model is to provide a kind of straight-tube diesel pump mounting hole, and it is relatively poor to solve existing segmented water pump mounting hole coaxality, causes when casting, being prone to produce in the cavity between the two joint mounting holes adding a sand and the inconsistent difficult problem of wall thickness.
For achieving the above object, the diesel pump mounting hole that the utility model provided is the straight cylinder type structure, and the water pump mounting hole is through the casting processing moulding.
The remarkable result of the utility model is: the diesel pump mounting hole is the straight cylinder type structure through casting processing; Assurance water pump mounting hole can not produce in the hole when casting processing and add the sand position; Can also guarantee simultaneously the wall thickness uniformity that the water pump mounting hole is peripheral, improve the up-to-standard rate of part; Can also improve the intensity of water pump mounting hole in addition, guarantee the reliability that water pump is installed, dwindle the difficulty and the cost of water pump mounting hole casting processing.
Description of drawings
Fig. 1 is the structural representation of existing diesel water pump mounting hole;
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, a kind of straight-tube water pump mounting hole, water pump mounting hole 5 is positioned at diesel-engine body 1.Wherein, Water pump mounting hole 5 is the straight cylinder type structure, has solved the difficult problem that existing segmented diesel pump mounting hole coaxality is difficult to guarantee, simultaneously; Straight cylinder type water pump mounting hole 5 is when casting processing; Can in water pump mounting hole 5, not form and add the sand position, can guarantee the wall thickness uniformity that water pump mounting hole 5 is peripheral, improve the up-to-standard rate of part; In addition, can also improve the intensity of water pump mounting hole 5, guarantee the reliability that water pump is installed, dwindle the difficulty and the cost of casting processing.
