Description
Technical field
The utility model relates to automobile component, particularly a kind of gasoline filter.
Background technique
The gasoline filter of prior art is metal shell, and when producing, mostly be seaming between housing with end cap and be connected or argon arc welding connection, complex process, manufacturing efficiency is low, and quality is unstable; And filter core and the connection of housing mostly to be glue bonding, operation is many, and material is many, and cost is high.
Summary of the invention
The object that the utility model will reach is to provide a kind of gasoline filter, and for friction welding is connected between its housing with end cap, technique is simple, and manufacturing efficiency is high, steady quality, and directly assembles between filter core and housing, and operation simplifies, and material is few, and cost is low.
In order to achieve the above object, the utility model adopts following technological scheme: a kind of gasoline filter, comprise the housing of plastic material and the end cap of plastic material, housing is the integrative-structure that single injection is formed, end cap is the integrative-structure that single injection is formed, housing upper is uncovered, end cap has joint, joint stretches into the uncovered of housing, joint is fitted and connected by friction welding and inner walls, filter core is provided with in housing, positioning part is provided with bottom filter core, positioning part and case inside bottom surface offset, joint is located between inner walls and filter core, cartridge top and end cap lower surface offset.
Further, housing lower end is provided with engine oil inlet, and engine oil inlet is provided with the conduit to downward-extension, and end cap is provided with machine oil outlet, and machine oil outlet is provided with the conduit upwards extended, and machine oil outlet has the connecting port stretched in filter core.
Further, the outer rim of end cap lower surface is provided with projection, and the outer rim of housing upper surface is provided with groove, projection to stretch in groove and with groove interference fit.
End cap and housing are located by projection and groove fit, and completed by the friction welding of joint and housing and be mutually permanently connected, joint is extended to form downwards by end cap lower surface, top inside joint and end cap lower surface and cartridge top edge offset, complete the radial location of filter core and axial location, a direction, positioning part bottom filter core and case inside bottom surface offseted filter shaft to another direction locate, thus fixing filter core.
Housing and end cap are completed by plastics injection moulding once-through, avoid conventional metals shell in production turnover and transportation process, cause product to scratch because colliding with, the quality problems such as distortion, avoid conventional metals shell produce and in using process because of oxidation and rusting the turbidity test of influential system.
After adopting technique scheme, the utility model tool has the following advantages:
For friction welding is connected between housing with end cap, technique is simple, and manufacturing efficiency is high, steady quality, and directly assemble between filter core and housing, operation simplifies, and material is few, cost is low, material recovery, after terminating its working life, by cutting open, can recycle by filter cleaner, be convenient to process, free from environmental pollution.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model.
Embodiment
Figure 1 shows that a kind of embodiment of the present utility model.
A kind of gasoline filter, comprise housing 1 and end cap 2, filter core 3 is provided with in housing 1, positioning part 31 is provided with bottom filter core 3, positioning part 31 and housing 1 inside bottom surface offset, housing 1 open topped, housing 1 lower end is provided with engine oil inlet 11, engine oil inlet 11 is provided with the conduit to downward-extension, end cap 2 is provided with machine oil outlet 21, machine oil outlet 21 is provided with the conduit upwards extended, machine oil outlet 21 has the connecting port 22 stretched in filter core 3, end cap 2 has joint 23, joint 23 stretches into the uncovered of housing 1 and fits with housing 1 inwall, joint 23 is located between housing 1 inwall and filter core 3, joint 23 and housing 1 interference fit, the outer rim of end cap 2 lower surface is provided with projection 24, the outer rim of housing 1 upper surface is provided with groove 12, projection 24 to stretch in groove 12 and with groove 12 interference fit, filter core 3 top and end cap 2 lower surface offset.
End cap 2 and housing 1 to be coordinated with groove 12 by projection 24 locates, and completed by joint 23 and housing 1 friction welding and be mutually permanently connected, joint 23 is extended to form downwards by end cap 2 lower surface, top inside joint 23 and end cap 2 lower surface and filter core 3 top offset, complete the radial location of filter core 3 and axial location, a direction, offseted another direction of filter core 3 axis of positioning part bottom filter core 3 31 and housing 1 inside bottom surface locate, thus fixes filter core 3.
Housing 1 is plastic casing 1.End cap 2, housing 1 are completed by plastics injection moulding once-through, avoid conventional metals shell in production turnover and transportation process, cause product to scratch because colliding with, the quality problems such as distortion, avoid conventional metals shell produce and in using process because of oxidation and rusting the turbidity test of influential system.
For friction welding is connected between housing 1 with end cap 2, technique is simple, and manufacturing efficiency is high, steady quality, and directly assemble between filter core 3 and housing 1, operation simplifies, and material is few, cost is low, material recovery, after terminating its working life, by cutting open, can recycle by filter cleaner, be convenient to process, free from environmental pollution.
Except above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
