Description
Technical field
The utility model relates to a kind of weld jig, specifically a kind of crane rotation body bearing erection welding fixture.
Background technology
Weld as a kind of manufacturing technology, in occupation of very important status in the development of modern industry.In actual production process, in order to ensure and improve the quality of products, weld jig is used widely in the process of welding.
For the weldment of shape and complicated structure, first need to carry out assembling and positioning weldering; Namely according to product drawing and technological requirement, the relative position of part each in weldment or parts is prepared to assemble up, and adopt welding method tentatively to carry out point admittedly, i.e. so-called tack welding.
When assembling and positioning is welded, for the weldment that relative position relation is fairly simple, be all adopt artificial line to ensure relative position between each assembly parts substantially.But for having the weldment of complicated positioning relation, adopt artificial line to be very difficult or perhaps impossible for relative position between guarantee Assembly part; Adopt artificial line simultaneously, be also difficult to ensure that product has higher uniformity, the error caused in assembling and positioning weldering will affect postorder machined sequence, cause that product size is overproof scraps.
As shown in Figure 1, revolving body bearing 1-3 realizes by welding with being connected between vehicle frame 1-1, according to drawing and technological requirement, need guarantee three technical parameters: 1) revolving body bearing 1-3 and large seat ring 1-2 axiality, 2) revolving body bearing 1-3 upper surface and the large seat ring 1-2 upper surface depth of parallelism and difference in height, the 3) relative position of revolving body bearing 1-3 upper screwed hole and large seat ring 1-1 upper screwed hole.
Current revolving body bearing assembling and positioning weld jig as shown in Figure 2, is changed a social system by hot rail I-steel 1-4 and is formed; Assembling as positioning datum using fixture lower surface during erection welding, by manually ruling, adopting angle square and tape measure auxiliary positioning to ensure relative position between revolving body bearing 1-3 and large seat ring 1-2.
Can draw from above-mentioned assembling mode, its working method brings following defect:
(1) assembling and positioning process adopts artificial line to ensure revolving body bearing relative position, and workman is difficult to accomplish to ensure accurate location all the time in scratching process, and therefore spelling point precision is relatively poor, and is subject to craftsmanship's impact;
(2) in assembling and positioning welding process, workman accounts for more than 80% the time of ruling, and the also corresponding increase in working time of workman, increases labor strength, also improve production cost simultaneously.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of crane rotation body bearing erection welding fixture, can realize the quick and precisely erection welding of center steering body bearing, improves workman's efficiency simultaneously and reduces fixture manufacturing cost.
To achieve these goals, the technical solution adopted in the utility model is: a kind of crane rotation body bearing erection welding fixture, and it comprises base components girder;
Described girder both sides are provided with hanger, two ends by general-purpose interface assembling and positioning block, are provided with the location-plate mated with revolving support seat on the downside of girder interfix hole loading central shaft, center;
Described locating piece is also provided with position fixing handle.
Described locating piece is welded by base plate I, gusset I and riser; Wherein, base plate is offered multiple locating hole.
Described location-plate shape is stepped, it has locating hole and positioning step, also offers multiple fabrication hole simultaneously.
Described girder is welded by shrouding, nutplate I, square steel tube, nutplate II, base plate II and gusset II; Described square steel tube specification is square steel tube 60X60X4.
Described central shaft is welded by bearing pin and plate, plate is offered for fixed center axis, the locating hole that prevents it from use coming off.
Compared with existing positioning welding fixture, the utility model has the following advantages:
(1) by changing locating piece and location-plate, different product assembling needs can be met; When large Dimension of Saddle Ring change, only need the transformation of the way or redesign locating piece to meet instructions for use; Make frock have stronger versatility, be conducive to fixture and realize modularized design;
(2) use element based on girder when different product uses, reduce fixture manufacturing cost and production cycle, and then the new product manufacturing cycle can be reduced, product is come into the market sooner;
(3) adopt locating piece to position revolving body bearing, workpiece assembly precision is determined by fixture, reduces the dependence to craftsmanship, reduces human cost;
(4) in assembling process, use fixture to position product, workman's line can be cancelled, reduce labor strength.
