Abstract
The invention discloses a method for connecting an oil injector base and an oil pipe. A fuel distribution pipe and the injector base are closely and fixedly connected through the expanded flanging of a core-pulling rivet. The method has the advantages of simple and convenient processing technology and stable and reliable processing quality, thus improving the efficiency of production.
Description
Technical field
The present invention relates to technical field of engines, concrete relate to the oil sprayer base in a kind of fuel engine oil supply system and the connecting means of oil pipe.
Background technique
At present, be connected manufacturing procedure between oil sprayer base and the fuel dispensing tube, adopt resistance welding to process more.
Because the resistance welding process is quite complicated, comprised multiple influence factor, for example: the distance of materials to be welded, electric current, electrode pressure, current"on"time, electrode end surface shape and size, shunting, solder joint isolated edge, thickness of slab, workpieces surface condition etc., and interknit between these factors, certain interaction effect is arranged.Simultaneously, the instantaneity that the invisibility of nugget and welding process are carried out in the welding process in addition, control brings bigger difficulty to welding quality.
Except that the difficult control of welding quality, and owing to be that the whole joint between oil sprayer base and the fuel dispensing tube is welded, bonding area is bigger, causes manufacturing efficiency on the low side; And there is the destruction to material itself in part in welding process.
Self-plugging rivet is simple to operate, has good fastening effect, is widely used in industries such as building, electromechanics, petrochemical industry, light industry, automobile making, decoration, and being connected of oil sprayer base and fuel dispensing tube finished in the processing of alternative resistance welding.
Summary of the invention
Technical problem solved by the invention is to provide the connecting means of a kind of oil sprayer base and oil pipe.
Technical problem solved by the invention can realize by the following technical solutions:
The connecting means of a kind of oil sprayer base and oil pipe is characterized in that, comprises the steps,
(1), perforate on the oil pipe that is mounted the oil sprayer base
Adopt stamping process on oil pipe, to leave the through hole that a diameter conforms to oil sprayer base external diameter;
(2), the oil sprayer base is fixed in the through hole of oil pipe
The oil sprayer base is inserted earlier in the through hole of oil pipe, insert the mould of loosing core from oil sprayer base top then, the mould riveted of loosing core is expanded, make inner expansion of oil sprayer base be fixedly connected on the oil pipe.
(3), take out the mould of loosing core
The mould of will loosing core takes out from the oil sprayer base, checks whether connection is qualified.
The described mould of loosing core is the automation mould of loosing core, and the mould of loosing core has can the expand expansion-head of action of a front end.
Beneficial effect, after the scheme more than adopting connected oil sprayer base and oil pipe, join strength was greater than 200N/mm
2, steady quality is reliable; Mould is the automation mould of loosing core owing to loose core, and makes manufacturing efficiency be improved; Avoided to destroy to the material of part own.
Description of drawings
Fig. 1 is the undressed preceding schematic representation of oil sprayer base and fuel dispensing tube;
Fig. 2 is the schematic representation that inserts self-plugging rivet in oil sprayer base and the fuel dispensing tube;
Fig. 3 is self-plugging rivet schematic representation behind the expansion flange in the oil sprayer base.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, the connecting means of a kind of oil sprayer base of the present invention and oil pipe, fuel dispensing tube 2 and oil sprayer base 1 as shown in FIG., its course of working is as follows:
At first, oil sprayer base 1 correspondingly is installed on the through hole of fuel dispensing tube 2;
Then, self-plugging rivet 3 inserts oil sprayer base 1, and insertion depth slightly is deeper than the degree of depth of oil sprayer base 1;
Then, taking-up is loosed core, and causes oil sprayer base 1 outside dilatancy, stays the shirt rim 4 outside side stays in the oil sprayer, remains oil sprayer base 1 and tightly links to each other with fuel dispenser 2, and both tighten together to make it.
Processing technology of the present invention is simple and convenient, stable processing quality is reliable, has improved manufacturing efficiency.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
1. the connecting means of oil sprayer base and oil pipe is characterized in that, comprise the steps,
