Abstract

The utility model relates to a structure connected to a metal plate, comprising a slab and a meeting post, wherein the slab is made of metal and the meeting post is also made of metal, a lalongate joint flange is arranged at the lower end of the meeting post, an annular casing plate is sleeved outside the joint flange to enlarge the joint field, and an adhesion agent is also positioned between the top surface of the slab and the end surface of the meeting post.

Description

The structure that a kind of sheet metal face is followed

Technical field

The utility model relates to the structure that a kind of sheet metal face is followed, and is meant the fixed sturcture of turnbuckle screw post on a kind of thin metal base plate that is applicable to the mobile computer class especially.

Background technology

The thickness of mobile computer is done thinner and thinner, also attenuation of base plate relatively, because base plate is for to make with metal, usually with aluminium sheet the material of the most normal use, because aluminium sheet has goodish robustness, but some screw columns will be set thereon, can combine with computer parts such as motherboards, screw column is for to make with metal material, with Fig. 1 demonstrate with a screw column 12 with the stereoscopic-state of sheet metal 11 before not joining, generally make and engage two kinds of assemblies in two ways, a kind of is heated type, as shown in Figure 2, be embedded type, adopt same material, joint is desired in heating, but can form the overshooting shape of a little at the outside surface of sheet metal 11, and cause the surface plain, still need and grind, more time-consuming taking a lot of work also reduced integral aesthetic property; Another kind method is a welded type, as shown in Figure 3, utilize the mode of spot welding to engage, the periphery of welding screw column 12 is to sheet metal 11, it also is high thermal processing method, also can produce outstanding and aesthetic problem as hereinbefore, so known manner is only applicable to the behaviour in service of slab, all causes surface irregularity all to need to carry out the surface and handle again, and because of adding thermal weld, carry out anodizing at the construction rear, so that sheet metal 11 insulatings, relatively, the made finished product of preceding method is not fine, and on the sheet metal of the 1mm of inapplicable expection processing.

Summary of the invention

The purpose of this utility model is to propose the structure that a kind of sheet metal face of being made up of plate, bond post and solid is followed, the mode of its combination is easy, and the structure pulling force is strong, and outside surface does not produce any variation, avoid following process, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it comprises:

One metal sheet;

One bond post, this bond post have a horizontal joint bead of stretching, and the bottom of bond post is followed mutually with metal sheet;

One solid, it is being executed between the surface that engages the bead end of plate and bond post.

Characteristics of the present utility model are: it can produce with bond post the connectivity between metal of the same race and dissimilar metal between plate, make the mode of joint easy, the structure of finished product has stronger pulling force, to produce better product, the most important thing is not produce any variation at outside surface, need not following process, and helpful to the technology of integral body, is that to be as thin as the following person of 1mm all applicable.

Specific implementation method

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.Extremely shown in Figure 5 as Fig. 4, the structure that it is followed for a kind of sheet metal face of the utility model, it has a plate 21, makes with metal; Also have at least one bond post 22, it is also made with metal, wherein is provided with screw for screwing togather usefulness, and the lower end of bond post 22 has a horizontal joint bead 23 of stretching; And a solid 24, it is being executed between plate 21 end faces and bond post 22 bottom faces (end face with bead of engaging 23).Wherein plate 21 can be aluminium matter, and bond post 22 is any material, is generally copper or its alloy etc.

As Fig. 6 and shown in Figure 7, roughly identical with Fig. 4, engaging bead 23 is to show with the hexagonal shape, but do not exceed with above-mentioned shape, so long as outstanding can the corresponding shape that engages all can be arranged, socket one ring-type cage plate 25 outside the joint bead 23 of bond post 22 also wherein enlarges the engaging zones of bond post 22 bottom faces with the annular surface of ring-type cage plate 25; In Fig. 6, ring-type cage plate 25 is for to have round outside and inner edge, make its inner edge and hexagonal shape engage bead 23 join (engaging) through punching press fixing, the joint bead 23 of bond post 22 produces bigger surface of contact with the underrun solid of ring-type cage plate 25 24.Solid 24 is epoxy resin (epoxy), and it has high peel strength.High intensity of shear, high impact strength, anti-chemical and solvent borne and anti-electrical specification.

Manufacturing process of the present utility model is in proper order:

(a) shaping of metallic plate.

(b) shaping of metallic bond post;

(c) plate carries out anodizing, to produce insulativity;

(anodizing is the generation insulation processing, and makes its surface hardening reduce the generation of scratch and oxidation)

(d) bonding station of plate carries out the decontamination processing.

(e) bonding station of bond post carries out the decontamination processing;

(f) bonding station of bond post (bottom) or plate (end face) carries out a glue; Be generally and on plate, carry out a glue (aforesaid solid).

(g) bond post is connected on the plate;

(h) putting into baking box is heating and curing; For in 200 ℃, carrying out promptly taking out in 4 minutes, reach

(i) normal temperature leaves standstill cooling.

Wherein (d) step can make plate bonding station surface earlier through grind or (e) step can make bond post the bonding station surface earlier through grinding, make its finished product then better.Through above-mentioned made finished product, through tensile test, all verified standard value that is much better than, method of the present utility model is truly feasible.

Structure in sum and mode, produce good goods with specific technology, can find that the plate surface is smooth more, the bottom of bond post expansion forms more large tracts of land or it is best to follow property, and the utility model carries out step for adhering through the anodizing rear, make plate directly make finished product, need not to send processing again back to after bonding, can save the cost of transportation, so the utility model is compared with known technology, applicability is better, also can provide good usability; Fully different with known technology.

Above-described is the detailed description and the accompanying drawing of preferred embodiment of the present utility model; be not to be used for limiting the utility model; all scopes of the present utility model should be as the criterion with following claim scope; the embodiment and the approximate construction of all spirit variations similar with it with the claim scope all should be contained in the scope of the utility model claims protection.
