A kind of solder horn assembly
Technical field
The utility model relates to a kind of solder horn assembly.
Background technology
The solder horn assembly in order to guarantee to change the uniformity that the front and back solder horn is eaten tin face position, can arrange a solder horn detent mechanism for the solder horn assembly usually when changing solder horn.The solder horn assembly of existing band positioning function, substantially all be to process or fix a thick cylinder at the solder horn afterbody, do the structure of steel ball chucking or boss chucking then at the cylinder tail end, such structure manufacturing procedure is many, complicated, change inconvenience, cost is also high.
The utility model content
Technical problem to be solved in the utility model provides a kind of solder horn assembly simple and easy, that cost is low of processing, and it is convenient, simple, fast that solder horn is changed, and guarantees to change the uniformity that solder horn front and back solder horn is eaten tin face position.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of solder horn assembly comprises heating core, weldering penholder, positioning tube, solder horn and solder horn locking nut; The rear portion of described heating core is fixed in the weldering penholder; Described positioning tube is fixed on the front portion of heating core; Described solder horn cooperates by flat position with positioning tube; Described solder horn locking nut is threaded with positioning tube, and the locking solder horn.
A kind of solder horn assembly also comprises steel bushing and heating core locking nut; Described steel bushing is enclosed within the rear portion of heating core; The inside of the front portion of described steel bushing and heating core locking nut is equipped with the conical surface; Described heating core locking nut is threaded with the weldering penholder, and steel bushing and heating core are locked in the weldering penholder.
First kind of optimized technical scheme: a kind of solder horn assembly also comprises anchor ear; Cone match on described anchor ear and the positioning tube is fixed on positioning tube the front portion of heating core.
Second kind of optimized technical scheme: described positioning tube is welded on the front portion of heating core.
After having adopted technique scheme, the utlity model has following beneficial effect: (1) solder horn of the present utility model cooperates by flat position with positioning tube, this structure has not only been removed the process that the adjustment solder horn is eaten the tin face in the solder horn process of changing from, reduced the time of changing solder horn, improved solder horn and eaten the repetitive positioning accuracy of tin face in welding process, improved operating efficiency, and solder horn processing is simple and easy, cost is low, greatly reduces the replacement cost of solder horn.
(2) positioning tube of the present utility model is fixed on the front portion of heating core, and this structure makes solder horn can do short and smallly relatively, thereby makes that solder horn thermal capacity is big, and it is fast to melt tin speed, improves the scolding tin operating efficiency.
(3) heating core had both circumferentially been held in the steel bushing of the utility model utilization band conical surface and locking nut locking tightly, axially held out against heating core again, such heating core locking mode, make things convenient for the replacing of heating core, significantly reduced the time of changing heating core, improved operating efficiency.
(4) the utility model provides tight-holding type and welded type two kinds of fixed forms on the heating core for positioning tube is fixed on, and this fixed form has reduced the overall number of parts of electric iron, has saved manufacturing cost.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the structural representation of embodiment 1 of the present utility model.
Fig. 2 is the structural representation of embodiment 2 of the present utility model.
Label in the accompanying drawing is:
Heating core 1, weldering penholder 2, positioning tube 3, solder horn 4, solder horn locking nut 5, steel bushing 6, heating core locking nut 7, anchor ear 8
The specific embodiment
(embodiment 1)
See Fig. 1, the solder horn assembly of present embodiment comprises heating core 1, weldering penholder 2, positioning tube 3, solder horn 4, solder horn locking nut 5, steel bushing 6, heating core locking nut 7 and anchor ear 8.
Steel bushing 6 is enclosed within the rear portion of heating core 1.The inside of the front portion of steel bushing 6 and heating core locking nut 7 is equipped with the conical surface.Heating core locking nut 7 is threaded with weldering penholder 2.When tightening heating core locking nut 7, the conical surface of heating core locking nut 7 inside holds out against the conical surface of steel bushing 6 front portions, makes steel bushing 6 not only circumferentially tighten up heating core 1 but also axially hold out against heating core 1, thereby steel bushing 6 and heating core 1 are locked in the weldering penholder 2.Cone match on anchor ear 8 and the positioning tube 3 is fixed on positioning tube 3 front portion of heating core 1.Solder horn 4 cooperates by flat position with positioning tube 3.Solder horn locking nut 5 is threaded with positioning tube 3, and locking solder horn 4.
(embodiment 2)
See Fig. 2, present embodiment is substantially the same manner as Example 1, and difference is: positioning tube 3 directly is welded on the front portion of heating core 1, does not need to arrange anchor ear 8 and holds positioning tube 3 tightly.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
