Abstract
The invention discloses a fixed seat structure of the oil pump of a plastic fuel tank, which is characterized in that a metal clamp ring and a plastic part are inject-molded as a whole and the oil pump is connected and fixed with the metal clamp ring while the plastic part is fixed with the plastic fuel tank. In the invention, the metal clamp ring and the plastic part are inject-molded together and then welded onto the plastic fuel tank, and the oil pump and the metal clamp ring are arranged together, thus solving the problem of fixing the oil pump on the plastic part and possessing good leak-tightness.
Description
Technical field
The present invention relates to automotive field, particularly relate to a kind of plastic fuel tank oil pump fixed seat structure.
Background technique
Fuel pump is installed in the fuel tank, and fuel tank is a metal material usually, and therefore fixedly fuel pump is more or less freely.At present, a large amount of plastic fuel tanks occurs, therefore, also just brought fuel pump how to be fixed on the problem of plastic fuel tank.
Summary of the invention
The purpose of this invention is to provide and a kind of fuel pump is fixed on fixing device in the plastic fuel tank.
For achieving the above object, technological scheme of the present invention provides a kind of plastic fuel tank oil pump fixed seat structure, metal clasp and plastic injection-moulded into a single integrated structure, described working of plastics is fixedlyed connected with plastic fuel tank, oil pump and described metal clasp are connected and fixed, and described oil pump fixed seat is provided with a breach.
Wherein, described working of plastics and fuel tank are fixing by welding.
Technique scheme only is an optimal technical scheme of the present invention, has following advantage: by with metal clasp and the common molding and forming of plastics, be welded on the plastic fuel tank, then oil pump and metal clasp are installed together, solve the problem that oil pump is fixed on working of plastics, and had good sealing property.
Description of drawings
Fig. 1 is the connection diagram of the metal clasp and the working of plastics of the embodiment of the invention;
Fig. 2 is the A-A sectional view among Fig. 1;
Fig. 3 is that embodiment of the invention oil pump is fixed on the structural representation on the plastic fuel tank;
Fig. 4 is the partial enlarged drawing of the B part among Fig. 3.
Wherein, 1: working of plastics; 2: metal clasp; 3: fuel pump; 4: plastic fuel tank 5:O RunddichtringO.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Fig. 1 is the connection diagram of the metal clasp and the working of plastics of the embodiment of the invention, and Fig. 2 is the A-A sectional drawing among Fig. 1.In conjunction with Fig. 1, Fig. 2, plastic Fuel Box for Automobile oil pump fixed structure adopts metal clasp 2 and working of plastics 1 common molding and forming, has solved the sealing of plastics and metal and the problem of large size welding, for fuel pump 3 provides new means of fixation.Fuel pump is installed and is cooperated with metal clasp, and the working of plastics of coated metal snap ring and plastic fuel tank 4 welding are fixing.Fig. 3 is that embodiment of the invention oil pump is fixed on the structural representation on the plastic fuel tank; Fig. 4 is the partial enlarged drawing of the B part among Fig. 3.By Fig. 3, Fig. 4 as can be seen, the embodiment of the invention has solved the fixation problem between fuel pump 3 and the plastic fuel tank 4 well, the metal clasp 2 that is welded on the plastic fuel tank 4 and assembles fuel pump 3 is structure as a whole with working of plastics 1, seal by O RunddichtringO 5, sealing detects not have and leaks, and has reached good sealing effect.Metal clasp is injection-moulded in the following steps of passing through of working of plastics, earlier metal clasp is put into mould, and when the mould matched moulds, working of plastics after product comes out, is given product protection with the typing rod by injection machine coated metal snap ring again.
Oil pump is fixed on the fuel tank by following steps, at first fuel tank is put on the welding machine fixing bottom-plate, guarantee that fuel tank is in place, then the oil pump fixed seat assembly is packed in the anchor clamps, the oil pump fixed seat assembly is provided with a gap position, this gap position should align with circular hole in the middle of the two-screw on the anchor clamps, requires to be in place.Start welding then, weld automatically, as note abnormalities and to stop welding immediately.Welding finishes and should carry out self check, and the gap position on the oil pump fixed seat assembly should align with four points of mark on the casing, is in a straight line.
As can be seen from the above embodiments, the embodiment of the invention is welded on the plastic fuel tank by with metal clasp and the common molding and forming of plastics, then oil pump and metal clasp is installed together, solve the problem that oil pump is fixed on working of plastics, and had good sealing property.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
