Abstract
The utility model discloses a detachable vertical coupling structure for two metal plates, which aims to solve the technical problem that the two metal plates can obtain higher positional accuracy, a connector can be used for convenient assembly and disassembly, the two metal plates only need to use a connecting position having small space occupation to realize rigid connection and screws having outer diameters which are larger than the thickness of the plates can be used for connection. Therefore, the two mutually and vertically connected metal plates at least have one connecting position, and one metal plate in every connecting plate is provided with mutually symmetrical outer lug bosses, rectangular notches connected with the outer lug bosses and used for accommodating the parallel surfaces of screw nuts and movable slots at the tail ends of the screws. The other metal plate is provided with through slots corresponding to the mutually symmetrical outer lug bosses and the screw holes of the screw nuts of the metal plate. The utility model is suitable for the mutually vertical rigid connection between two or a plurality of metal plates.
Description
Technical field
The utility model relates to metal sheet connection technique field, particularly a kind of Removable Type Two Metal Board Vertical Draw Bail.
Background technique
In mechanical industry, often need vertically to connect rigidly the three-dimensional structure part of two plates or the making of many plates.Many times, not only require to connect between the plate of back and can reach higher positional accuracy, and connect and conveniently to realize mounting or dismounting, even also be subjected to the restriction of structure space and require only to allow to have only a place to connect, and will occupy less space.But the connection of conventional method can not reach above requirement simultaneously.For example: riveted joint, welding, splicing and interference fit connect, and all can not realize convenient mounting or dismounting.As shown in Figure 1 regular screw threads connect, and two through holes are arranged on metal sheet 2, and the connection place is corresponding on the metal sheet 3 that another part is vertically connected processes two tapped holes, uses two screws 1 with its fastening connection then.As seen,, fail to retrain the degrees of freedom of rotating, thereby must adopt two groups or above scyewed joint could realize the rigid vertical connection of two plates around screw axis if only adopt a place to connect.Moreover, common scyewed joint, generally be to process through hole on the plate therein, on another plate, process tapped hole, adopt screw attachment, perhaps on two plates, all process through hole and adopt screw and nut to connect these two kinds of scyewed joint methods again, the diameter of the screw that adopts all must be less than the thickness of slab of coupled metal sheet, and linking intensity is just not enough when thickness of slab is little.
Summary of the invention
The technical problems to be solved in the utility model is to propose the vertical connecting structure between a kind of two metal sheets, make to connect between two plates of back and can reach higher positional accuracy, connection can conveniently realize mounting or dismounting, generally speaking, rigid joint is realized in the connection position that only need adopt a place to occupy less space between two plates, and can adopt the diameter of thread to connect than the big screw of coupled plate thickness of slab where necessary.
The technical solution that the utility model proposed is such: a kind of Removable Type Two Metal Board Vertical Draw Bail, comprise mutually vertical placed metal plate 11 and 13, and 12 pairs on screw 14 nuts, described vertical mutually metal sheet 11 that connects and the connection place between the metal sheet 13 have a place at least; In each connection place, described metal sheet 13 has the outer lug boss 13-2 of mutual symmetry and rectangular indentation 13-1 and the described screw 14 afterbody loose slot 13-5 of the held nut 12 parallel surface 12-1 that are attached thereto, and described metal sheet 11 has and the outer lug boss 13-2 of the mutual symmetry of metal sheet 13 and the corresponding groove of tapped hole of nut 12.The groove of described metal sheet 11 can be rectangular opening 11-1, also can be rectangular opening 11-1 and have the cylindrical hole 11-2 big than hole width at this hole 11-1 middle part, the groove of another can be for the rectangular indentation 11-3 of symmetry and the middle part between this two breach 11-3 have a cylindrical hole 11-4 mutually.The groove that screw 14 passes metal sheet 11 during connection is threaded with nut 12 in the rectangular indentation 13-1 that is placed on metal sheet 13, and this screw head end face closely contacts with the outer plate surface of metal sheet 11.
Decide by coupled metal sheet size and desirable strength, rigidity two required what connection places of the vertical connecting structure of metal sheet.In general, only need a connection place to get final product.
The connection process of each connection place is such: during connection, the outer lug boss 13-2 of plate 13 inserts in the rectangular opening 11-1 or breach 11-3 of plate 11, keep nut 12 in the rectangular indentation 13-1 of plate 13, this nut has a pair of or a pair of above parallel surface 12-1 that can retrain, the nominal diameter of thread of nut can be greater than this thickness of slab, thereby can reach higher linking intensity.The built-in nut 12 of screw 14 and plate 13 is by scyewed joint, and its screw head end face can be directly or compressed the outer plate surface of plate 11 by packing ring.The position setting principle of its stress surface is: leave certain distance between the stress surface that plate 13 contacts with nut 12 bottoms and plate 13 and the stress surface 13-4 that plate 11 contacts, so that the pressure of nut 12 directly do not affact on the plate 11, and guarantee to have enough intensity to exert all one's strength to be passed on the stress surface 13-4; The end face 13-3 of the outer lug boss 13-2 of the mutual symmetry of plate 13 and the distance between the stress surface 13-4 be less than the thickness of plate 11, the pressure of screw head or packing ring is only acted on the plate 11 and do not act on the outer lug boss end face 13-3.The rectangular opening 11-1 of the outer lug boss 13-2 of plate 13 and plate 11 or breach 11-3 are processed into movingly closely spaced or transition fit each other.Add aforesaid pair of screws 14 nuts 12, can reach connection and afterwards have higher positional accuracy between plate, can retrain whole 6 degrees of freedom of two plate relative movement again, realize the constraint fully of relative movement between two plates.
Compared with prior art, the utlity model has following beneficial effect: (1) vertical connection between two plates of back can reach higher positional accuracy.(2) owing to advantage with scyewed joint, thus for convenience detach.(3) only need adopt a place to occupy the connection place in less space generally speaking between vertical two plates that connect, can realize the constraint fully of relative movement between two plates.(4) can adopt the diameter of thread to connect in case of necessity, to reach bigger linking intensity than the big screw of coupled plate plate thickness.(5) the utility model is a kind ofly need not use mould, for example, and punching press, die casting, casting, injection moulding etc. and only can be built into the easy connecting structures of accurate complicated three-dimensional structure part with upper plate and screw-nut with two or two.In, during the multiple accurate complicated three-dimensional structure part of small lot batch manufacture, can shorten the manufacturing cycle and reduce production costs significantly.
The utility model is not only applicable to two mutual perpendicular rigid of metal sheet and connects, and is applicable to orthogonal rigid joint between the polylith metal sheet simultaneously yet.
