Each building block of above-mentioned frock all passes through the tight processing of numerical control device, can guarantee positioning accuracy separately, and enough strength and stiffness are arranged.
Be described further with the welding positioning principle below in conjunction with the structure of accompanying drawing the utility model.
Suiting, the door machine main structure body of welding production generally comprises girder a, supporting leg b, contact beam c etc. on the utility model.
Each parts and the utility model assembling sketch map when Fig. 6 makes up for the welding girder.
Girder a is generally the twin beams form, and every part can be split as main beam structure body d, contact end e and flange bearing f again.
When welding door main beam a; The top panel 4 of lower carriage 2 and upper bracket 1 following joins that panel 7 is vertical to be connected two groups; Between two groups at a distance of the distance of door machine cart span; The flange bearing f of four groups of completion of processing through the articulation bolt hole with bolt respectively positioning and fixing on four groups of two groups of upper brackets 1, join on the panel 6, be positioned over behind two groups of main beam structure body d centerings on the box-shaped weld bond of four groups of flange bearing f that positioning and fixing finishes, after the contact end e of four completion of processing connects two groups through the articulation bolt hole with bolt; Be positioned over respectively in the middle of the end of two groups of main beam structure body d, the vertical weld bond of contact end e is relative with main beam structure body d.
Between lower carriage 2 and upper bracket 1 touch panel connected vertically locating slot 12 is arranged, contact end e and flange bearing f all pass through the numerical control device Precision Machining before last frock Combination Welding.
Each parts of girder a are after the clamping that is positioned on the frock finishes; Earlier the weld bond between four groups of contact end e and the main beam structure body d is welded; After treating that the weld bond contraction distortion finishes; At last the weld bond between four groups of flange bearing f and the main beam structure body d is welded, welding production can reduce the influence of welding deformation to four groups of flange bearing f to greatest extent like this, guarantees the position degree of four groups of flange bearing f of whole girder a again.
Each parts and the utility model assembling sketch map when Fig. 7 makes up for the welding supporting leg;
Supporting leg b can be split as leg structure body g, supporting leg lower flange m and supporting leg upper flange n.
When welding door machine supporting leg b; The top panel 4 of lower carriage 2 and 8 vertical connections of the vertical panel of upper bracket 1; The horizontal panel 9 of four bearing diagonals 3 is used the bolt positioning and fixing with the top panel 4 of lower carriage 2 and the following panel 7 of joining of upright rami posterior superior frame 1 through the articulation bolt hole respectively with vertical panel 10; Between lower carriage 2 and touch panel that upright upper bracket 1 is connected locating slot 12 is arranged; Joining panel 6 on the upper bracket 2 is the benchmark that is located by connecting of flange bearing f and supporting leg upper flange n simultaneously, and is upright vertically state.The Precision Machining that numerical control device is all passed through on the relevant cooperation plane of door machine contact beam c, supporting leg lower flange m and supporting leg upper flange n.Supporting leg lower flange m two groups of completion of processing gets in touch on the connection bearing of beam c both side ends through the articulation bolt hole with bolt difference positioning and fixing in the door machine; The supporting leg upper flange n of two groups of completion of processing through the articulation bolt hole with bolt respectively positioning and fixing after joining panel 6 on two groups of upper bracket 1, with leg structure body g installing and locating between supporting leg lower flange m and supporting leg upper flange n.
Weld bond between supporting leg lower flange m, supporting leg upper flange n and the leg structure body g and reinforcement gusset are carried out Combination Welding; Welding production can reduce the influence of welding deformation to supporting leg lower flange m and supporting leg upper flange n to greatest extent like this, guarantees the position degree of the end flange of whole supporting leg b.
In the utility model, four door machine supporting leg b can be divided into two groups of Combination Welding making on this frock simultaneously; Simultaneously; When this frock Combination Welding door machine supporting leg b; The finish door main beam a that takes off this frock of Combination Welding just can get into next step operation (for example application) and continues to produce, and, in the Combination Welding manufacturing process of whole machine structure; Girder a that appearance and size is bigger and supporting leg b are in the station of horizontal positioned basically, have avoided the upset of the large-scale workpiece when respectively doing for oneself the benchmark welding production.So; The girder a and the supporting leg b of the structure fabrication frock welding production door machine through this main beam of gantry crane and supporting leg just can reach the control welding deformation, realize exchanging, avoiding upright or upset workpiece, reduce the place space requirement, shorten the production cycle, reduce the effect of producing cost etc. in batches with parts.
Need to prove that when making supporting leg b, the positioning reference that supporting leg lower flange m uses is the contact beam c of fine finishining in the utility model, certainly, the utility model also comprises the situation that is changed to contact beam c vertical stationary positioned benchmark.
The utility model can realize that above-mentioned embodiment just illustrates through necessary embodiment of not breaking away from of other, is not only, all in the utility model scope or the change that is equal in the scope of the utility model all surrounded by the utility model.
