Abstract

The utility model provides a hot-melt tool, which is applicable for melting and fixing a built-in fitting onto a housing. Wherein, the built-in fitting is provided with a plurality of through-holes for melting and fixing. The housing is arranged correspondingly with a plurality of hot-melt columns for melting and fixing and the hot-melt columns are separately provided in the through-holes. The center of the hot-melt columns is arranged with positioning holes. The hot-melt tool includes a plurality of melting joints which are positioned at right above of the hot-melt columns. The terminal ends of the melting joints are separately provided with an accommodating room which is arranged from inside to outside with a positioning heave which is in the form of a cone. During hot-melting, the melting joints will be moved downward in opposition to the hot-melt columns. And the positioning heave and the positioning holes will be aligned in a same vertical line, which will enable the hot-melt column to be pressed into the accommodating room and melt, and the hot-melt glue after the melting will be accommodated within the accommodating room.

[background technology]

Fixed form between two objects comprises the riveted joint of rivet, the locking of screw and the welding of hot melt post etc., and different objects can be selected corresponding fixed form.

The welding mode of hot melt post can be consulted Figure 1 and Figure 2, by a hot melt tool one fixture 20 is welded on the body 10, wherein, this fixture 20 is provided with some weldings through hole 21, and corresponding some weldings hot melt post 11 that is provided with on this body 10, and its center is provided with hole 110, and these hot melt posts 11 are arranged in respectively in these through holes 21, and this hot melt tool comprises a fixed jig 40, this fixed jig 40 is provided with some installing holes 43, be provided with female thread structure 431 in the installing hole 43, and some welded joints 30 are installed in these installing holes 43, one end of welded joint 30 is provided with a receiving space 31, this receiving space 301 can be in order to accommodate PUR, and being shaped as of this receiving space 31 is recessed spherical, and the other end of welded joint 30 is provided with external thread structure 33, and the centre position of welded joint 30 is provided with polygon prism structure 32, use for the erecting tools clamping, so that the external thread structure 33 of welded joint 30 and the female thread structure 431 of installing hole 43 are cooperatively interacted, thereby welded joint 30 is fixed on the fixed jig 40, and these welded joints 30 can move together along with fixed jig 40.

Before the welding, adjust the position of welded joint 30 so that welded joint 30 be located at respectively hot melt post 11 directly over; During hot melt, welded joint 30 is moved down with respect to hot melt post 11, when weld portion 31 is overlaid on the end of hot melt post 11, hot melt post 11 fusing, and the PUR after the fusing can be covered in the surface of fixture 20 and through hole 21 is covered, after PUR solidifies, form the cover layer 111 of skim shape, and cover layer 111 be shaped as the mushroom head, at this moment, fixture 20 is held between cover layer 111 and the body 10, thereby fixture 20 is fused on the body 10.

But adopt the hot melt tool of this kind structure, welded joint 30 can not accurately be located in the process that moves with hot melt post 11, and departing from appears in hot melt post 11 easily, make in following process, need expend great amount of manpower and place under repair in man-hour, the operation that makes is difficulty relatively, thereby increased production cost of products, the yield of the product that also makes reduces greatly, is unfavorable for improving the production efficiency of factory, because departing from appears in hot melt post 11 easily, be unfavorable for fixedlying connected between body and the fixture again.

In view of this, it is a kind of time saving and energy saving to be necessary to propose in fact, and the hot melt tool that helps applying.

[summary of the invention]

Main purpose of the present utility model is to provide a kind of and can accurately locatees and can suppress PUR excessive hot melt tool in reflow process.

For reaching above purpose, the utility model provides a kind of hot melt tool, this hot melt tool is applicable on welding one fixture to a body, wherein, this fixture is provided with some welding through holes, and corresponding some weldings hot melt post that is provided with on this body, and these hot melt posts are arranged in respectively in these through holes, and the center of this hot melt post is provided with locating hole, and this hot melt tool comprises some welded joints, these welded joints be located at respectively the hot melt post directly over, and the end of these welded joints is respectively equipped with a receiving space, and in the receiving space to outside be provided with positioning protrusion, and this positioning convex is coniform; During hot melt, welded joint is moved down with respect to the hot melt post, and the positioning convex that makes and locating hole be positioned on the same vertical line, can make the hot melt post be overlaid in the receiving space and fusing, and the PUR after the fusing can be contained in the receiving space.

Compared to prior art, welded joint is provided with a receiving space in the utility model, and in the receiving space to outside be provided with positioning protrusion, and this positioning convex is coniform; This receiving space can be accommodated PUR, help to suppress outwards overflowing of PUR, and positioning convex cooperates the locating hole on the hot melt post accurately to locate, and the hot melt post that makes is not prone to and departs from, make in following process, need not expend great amount of manpower and place under repair in man-hour, the operation ratio that makes is easier to, thereby greatly reduce production cost of products, the yield of the product that also makes improves greatly, help improving the production efficiency of factory, because the hot melt post is not prone to and does not depart from, help fixedlying connected between body and the fixture again.

In order to make architectural feature and function thereof that further understanding be arranged, cooperate diagram to be described in detail as follows now to the utility model hot melt tool:
