Abstract
The utility model relates to a kind of projection welding electrode, relates in particular to a kind of projection welding bolt keeper electrode.Comprise the first electrode and the second electrode that match, described the first electrode is provided with through hole, in described the second electrode, be provided with stepped hole, also comprise the sheet metal component that is positioned at described the first electrode upper surface, run through the first location insulation sleeve of described the first electrode through hole, be positioned at the bolt positioning hole of described the first location insulation sleeve medial surface, be positioned at the second location insulation sleeve of described the second electrode medial surface, and be located at the holddown spring between the first location insulation sleeve and the second location insulation sleeve.Beneficial effect is: adopt locate mode of the present utility model to ensure bolt position degree, adopt insulation sleeve to locate panel beating and bolt can to ensure the position degree of projection welding bolt simultaneously.In the situation that sheet metal component and bolt are all walked dimension limit deviation, the size maximum deviation of appearance is (0.1+0.1) ÷ 2=0.1mm, and in actual welding process, projection welding size effect is consistent with design, meets later stage matching requirements.
Description
Technical field
The utility model relates to a kind of projection welding electrode, relates in particular to a kind of projection welding bolt keeper electrode.
Background technology
In prior art, projection welding M10 bolt is that band punching hole sheet metal component is put in to electrode body upper surface, and weld bolt is installed in insulation sleeve.M10 bolt of projection welding, bolt thickness of slab is that 2.5mm, aperture are Φ 10.1mm, bolt root is made up of a high escape that is 8.8mm for 3.3mm, diameter, because part self technique cannot ensure bolt position degree, completely by stamping holes and bolt self poisoning, so there will be the fluctuation of (10.1-8.8) ÷ 2=0.65mm after welding, and accessory size tolerance is ± 0.5, add that the situation of super tolerance appears in sheet metal component welding to assembly, cause product quality defective, subsequent parts is installed difficulty and maybe cannot be installed.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides the projection welding bolt keeper electrode that a kind of welding quality is high.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of projection welding bolt keeper electrode, comprise the first electrode and the second electrode that match, described the first electrode is provided with through hole, in described the second electrode, be provided with stepped hole, also comprise the sheet metal component that is positioned at described the first electrode upper surface, run through the first location insulation sleeve of described the first electrode through hole, be positioned at the bolt positioning hole of described the first location insulation sleeve medial surface, be positioned at the second location insulation sleeve of described the second electrode medial surface, and be located at the first location insulation sleeve and the second holddown spring of location between insulation sleeve.
Described the first location insulation sleeve and the second location insulation sleeve are KCF insulation sleeve.
Beneficial effect is: adopt locate mode of the present utility model to ensure bolt position degree, adopt insulation sleeve to locate panel beating and bolt can to ensure the position degree of projection welding bolt simultaneously.In the situation that sheet metal component and bolt are all walked dimension limit deviation, the size maximum deviation of appearance is (0.1+0.1) ÷ 2=0.1mm, and in actual welding process, projection welding size effect is consistent with design, is less than ± 0.5 tolerance, meets later stage matching requirements.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
The second electrode in the drawings, 1, sheet metal component, 2, the first location insulation sleeve, 3, holddown spring, 4, the second location insulation sleeve, 5, the first electrode, 6, bolt positioning hole, 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of projection welding bolt keeper electrode, comprises the first electrode 5 and the second electrode 7 that match, and described the first electrode 5 is provided with through hole, in described the second electrode 7, is provided with stepped hole; Also comprise the sheet metal component 1 that is positioned at described the first electrode 5 upper surfaces, run through the first location insulation sleeve 2 of described the first electrode 5 through holes, be positioned at the bolt positioning hole 6 of described the first location insulation sleeve 2 medial surfaces, be positioned at the second location insulation sleeve 4 of described the second electrode 7 medial surfaces, and be located at the holddown spring 3 between the first location insulation sleeve 2 and the second location insulation sleeve 4.
Described the first location insulation sleeve 2 and the second location insulation sleeve 4 are KCF insulation sleeve.
Positioning principle:
1, first sheet metal component 1 is expanded, making KCF insulation sleeve, machining accuracy are 0～+ 0.1mm tolerance, and bolt positioning hole 6 is that bolt mounting-positioning holes, machining accuracy are 0～+ 0.1mm;
2, while welding, sheet metal component 1 is first installed, after locating, at bolt mounting holes 6 place's construction bolts, after the first electrode 5 hold-down bolts, is welded;
3, the first location insulation sleeve 2 falls by the contraction of holddown spring 3, and stud weld contact can contact compression with sheet metal component 1, by the first electrode 5 and the second electrode 7 conductive solder;
4, take sheet metal component 1, the first location insulation sleeve 2 after having welded away and act on homing by holddown spring 3, complete a weld cycle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. a projection welding bolt keeper electrode, comprise the first electrode and the second electrode that match, described the first electrode is provided with through hole, in described the second electrode, be provided with stepped hole, it is characterized in that, also comprise the sheet metal component that is positioned at described the first electrode upper surface, run through the first location insulation sleeve of described the first electrode through hole, be positioned at the bolt positioning hole of described the first location insulation sleeve medial surface, be positioned at the second location insulation sleeve of described the second electrode medial surface, and be located at the holddown spring between the first location insulation sleeve and the second location insulation sleeve.
