Abstract
The utility model provides an oil atomizer seat electric resistance welding tool structure. An existing electric resistance welding tool structure is adjusted and improved, and a locating pin is additionally arranged at the left end of the tool structure and used for locating fuel oil guide rails and stopping movement of the fuel oil guide rails. The outer side of the corresponding position of each electrode is additionally provided with stopping blocks used for locating oil atomizer seats, the stopping blocks of all electrodes are the same in number, and relative positions of the fuel oil guide rails and the oil atomizer seats are located accurately. An improvement of the tool structure enables the oil atomizer seats and the fuel oil guide rails to be located accurately, a welding current can pass through a connection position of each oil atomizer and each fuel oil guide rail, the fact that enough heat is produced to enable protruded points at the bottoms of the oil atomizer seats to be melted is guaranteed to the maximum, and the oil atomizer seats can be firmly combined with the fuel oil guide rails.
Description
Technical field
The utility model relates to a kind of oil injector seat electric resistance welding tool structure, belongs to the manufacturing field of automobile engine fuel rail.
Background technology
The fuel rail of each model includes the oil injector seat that 3-6 does not wait, and oil injector seat is connected with atomizer, bear be with fuel oil bottom oil injector seat with hole that fuel rail is connected the effect of uniform distribution to the atomizer.The driving engine burns after fuel injector is with fuel-oil atmozation.Therefore precision and reliability to its location have higher requirement.
Existing oil injector seat electric resistance welding tool structure is so that there are many defectives in the projection welding mode of oil injector seat.As shown in Figure 1, first oil injector seat 5 is placed on the bottom electrode 3 successively, then fuel rail 6 is placed on the fixed mount 4 on the bottom electrode 3, so that the hole on the fuel rail 6 contacts the location with each oil injector seat 5, after will working as at last the electrode tip 2 and bottom electrode 3 compression fuel rails 6 and oil injector seat 5 of top electrode 1, the projection welding electric current of equipment can disperse shown in the direction of arrow among Fig. 1, can cause oil injector seat 5 welding to be connected with fuel rail 6 afterwards insecure, the defective that easily drops.In addition, existing oil injector seat electric resistance welding tool structure can only accomplish that oil injector seat is with respect to the accurate location of electric resistance welding tool structure, can't guarantee the high accuracy of fuel rail and its position, therefore the product after the processing needs the correction in later stage to guarantee the qualified of product size often, and product quality and production cost are wayward.
The utility model has improved the structure of oil injector seat electric resistance welding frock, make between oil injector seat and the fuel rail and can locate accurately, and can make welding current seriatim, the junction of concentrated area by each oil injector seat and fuel rail, farthest guarantee to produce enough heats the salient point of oil injector seat bottom is melted, make it and the fuel rail strong bonded.
Summary of the invention
In order to locate the problems such as inaccuracy, welding quality be unstable between the fuel rail that solves automobile engine and the oil injector seat, the utility model provides a kind of New-type fuel injector seat electric resistance welding tool structure.
The oil injector seat electric resistance welding tool structure that the utility model provides is adjusted existing electric resistance welding tool structure and improve, and sets up an alignment pin 8 at the tool structure left end, is used for location fuel rail 6, does not allow it move; Set up the block 7 of equal number in the outside of each top electrode 1 correspondence position, be used for location oil injector seat 5; The relative position of fuel rail 6 and oil injector seat 5 is accurately located like this.Wherein alignment pin 8 is cylindrical, and its external diameter equals the internal diameter of fuel rail 6 to be processed.
The beneficial effect that the utility model brings: former cause oil injector seat is done the location, and the mode that the projection welding electric current reaches each oil injector seat again by fuel rail first changes to by the hole of fuel rail and the block newly established and does the location, and electric current reaches the purpose that improves positioning accuracy and welding quality by the mode that conducts to again fuel rail behind each oil injector seat one by one.
Description of drawings
Accompanying drawing 1: electric current conduction figure when former oil injector seat electric resistance welding tool structure uses;
Accompanying drawing 2: utility model oil injector seat electric resistance welding tool structure figure;
Accompanying drawing 3: electric current conduction figure when utility model oil injector seat electric resistance welding tool structure uses.
The specific embodiment
As shown in Figure 3, at first the utility model tool structure is fixed on the Special projection welding equipment during operation, then fuel rail 6 is placed on bottom electrode 3 and the fixed mount 4, and the one end is enclosed within on the alignment pin 8 of electric resistance welding tool structure left end, so that self maintains static; Then successively oil injector seat 5 is placed on the position in hole corresponding on the fuel rail 6, guarantees that the catch on the oil injector seat 5 is stuck in the corresponding hole, and lean against on the corresponding block 7 so that self not occurrence positions skew; After the energising of projection welding opening of device, top electrode 1 all falls simultaneously, electrode tip 2 inserts oil injector seat 5 internal diameters, by the pressure on the top electrode 1 oil injector seat 5 and fuel rail 6 are compressed, each electrode tip 2 produces heavy current successively simultaneously, oil injector seat 5 and the salient point place that its below fuel rail 6 is connected by its relevant position produce high heat salient point are melted, and reach the purpose of firm welding.
Claims (2)
1. oil injector seat electric resistance welding tool structure, comprise top electrode (1), electrode tip (2), bottom electrode (3) and fixed mount (4), it is characterized in that: set up an alignment pin (8) at original tool structure left end, set up the block (7) of equal number in the outside of each top electrode (1) correspondence position.
2. a kind of oil injector seat electric resistance welding tool structure described in according to claim 1 is characterized in that: described alignment pin (8) is for cylindrical, and its external diameter equals the internal diameter of fuel rail (6) to be processed.
