Abstract
The invention provides a welding web shaft rib plate riveting and welding support device for a motor, and relates to a welding web shaft rib plate riveting and welding support device for a large high-voltage motor. The device is mainly used for solving the following problems: when welding of multiple groups of symmetrical rib plates is performed on the rotating shaft of the high-voltage motor, in order to prevent the rotating shaft from deforming and meet the requirement of rotor operation for dynamic balance, a general operating mode is to arrange a cushion block below the rotating shaft or support the rotating shaft on a V-shaped sizing block, since the surface of the rotating shaft is relatively smooth, the deadweight is relatively great and the torque is relatively small, during back-and-forth rolling, time and labor are wasted, the locating is inconvenient, the efficiency is low and the labor intensity is high. According to the device provided by the invention, two welding web shaft pair finished blanks formed by welding upper support plates on bed plates are connected to the bottom plate of a bracket through bolts. According to the device, the welding web shaft pair finished blanks are divided into two steel plates for splicing, so that the manufacturing difficulty is reduced; roller wheels are additionally arranged on the welding web shaft pair finished blanks, so that the rotating shaft is supported by the roller wheels, sliding friction is replaced by rolling friction, the frictional resistance is reduced, the rib plates are guaranteed to slightly depart from the balance position, and the labor is saved during rotation, so that the labor intensity is reduced, and the efficiency is improved.
Description
Technical field
The present invention relates to the riveting of a kind of machine shaft gusset, weldering bracing or strutting arrangement, particularly the riveting dress of large high-voltage motor weldering muscle axial rib plate, rotation, the bracing or strutting arrangement in the welding operation process.
Background technology
The large and middle size motor great majority adopt weldering muscle axle construction, and its advantage is to strengthen ventilation, the heat radiation of motor, has also reduced the cost of manufacture of rotating shaft.And axle is the core component of motor, and its quality requirement is very high.As the rivet welding process is not controlled, can cause the cracking of the larger distortion of axle even weld seam, singly not that subsequent handling adds and the unstable of size can occur man-hour, also can have influence on the cast-aluminum rotor hot jacket to welding the dynamic balancing that forms whole rotor behind the rotor on the muscle axle.For preventing welding deformation, the gusset welding will be adopted multilayer, multiple tracks, be symmetrically welded, and is about to axle to be turned to behind gusset two side weld balanced welding one decks the ground floor that another bars position of gusset symmetry therewith welds two side welds.So repeatedly, until all weldering is full with the weld seam of all gussets, before the weldering muscle, also need rotating shaft to draw circumference graduation line and the axial location line of gusset during the welding equipment gusset in addition, so all need repeatedly rotating shaft.For ease of riveting dress and welding, generally be to be placed on rotating shaft on the sleeper or to be placed on the V-shaped parallels, because the rotating shaft smooth surface is conducted oneself with dignity heavier, torque is less, and when rolling back and forth in the V-type bearing, frictional resistance is large, wastes time and energy, and efficient is very low, and labor strength is large; Come the moving location that is not easy to again of rollback at sleeper.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, and provide a kind of for weldering muscle axle riveting dress, the welding of the different diameters of axle, different length support to becoming tire.
Technical solution of the present invention is: electric welding muscle axial rib plate rivet welding bracing or strutting arrangement is that upper supporting plate is divided into two and is welded on the bedplate and consists of weldering muscle axle to becoming tire, with two weldering muscle axles to becoming tire to be bolted on the support base plate.
Two weldering muscle axles described in the technical solution of the present invention are provided with V-shaped groove to the upper end of the upper supporting plate of one-tenth tire, and the V-shaped groove both sides are provided with roller.
Beneficial effect of the present invention is as follows:
A. saved to drop into and reduced production cost, easily manufactured practicality: adopt the welding erection method, at weldering muscle axle to becoming when in the tire roller being installed, only need paired Steel Plate Guide Drill fraising, two block plates are put on to be welded on the bedplate behind bearing pin and the roller and are got final product, and avoid a technique difficult problem that exists for getting out of the way roller installing space processing deep trouth at the monoblock steel plate.
B. reduced labour intensity, improved efficient: rotating shaft support is on roller, and roller rotates together during rotating shaft, and frictional resistance is rolling friction, and the sliding-frictional resistance when directly rotating in the V-type bearing than rotating shaft is much smaller; In riveting, when welding gusset, rotation is easily laborsaving repeatedly, greatly enhances productivity for the high-voltage motor rotating shaft.
C. improve the quality of products: common V-type bearing, because frictional resistance is large, even the gusset of weldering is not in the bottom first, rotating shaft can not rotated yet, and reaches balance; After adopting roller, frictional resistance is little, and the gusset of weldering can be parked in the bottom first, departs from the equilbrium position little, and when welding symmetrical muscle, symmetry can better guarantee, guarantees rotor balancing.

The specific embodiment
Shown in Fig. 1,2,3,4, upper supporting plate 5 is weldingly fixed on the bedplate 4 consists of weldering muscle axle to becoming tire 2, the identical weldering muscle axle of two shapes is to becoming tire 2 according to the length of machine shaft 3, be bolted on and consist of bracing or strutting arrangement of the present invention on the support base plate 1, the upper end of the joint of two upper supporting plates 5 forms a V-shaped groove, upper supporting plate 5 in the V-shaped groove both sides is symmetrically installed with roller 7, and roller 7 passes roller 7 centre bores by bearing pin 6 and is installed on the upper supporting plate 5.When using the present invention as support, first machine shaft 3 is lifted into weldering muscle axle on the V-shaped groove that becomes tire 2, by welding the muscle axle to becoming the roller 7 support motor rotating shafts 3 on the tire 2, at circumference graduation line and the axial location line 8 of machine shaft 3 picture gussets 9; When machine shaft 3 weldering gusset 9, during such as 3 a pair of gussets 9 of weldering of machine shaft, in machine shaft 3 uppers welding gusset 9, segmentation spot welding; Again will be the gusset 9 of spot welding forward the most the next of rotating shaft 3 to, weld symmetrical gusset 9 at rotating shaft 3 uppers, full weld welds, and again with machine shaft 3 Rotate 180s °, gusset 9 full welds of segmentation spot welding is welded; For the machine shaft 3 of many groups balanced welding gusset, first successively with all gussets 9 in accordance with regulations the symmetrical spot welding of angle live; Rear symmetry is lived in all gusset 9 spot welding weld all gussets 9.When making the riveting of weldering muscle axial rib plate, weldering bracing or strutting arrangement, by whole V-type bearing is resolved into two steel plate splicings, save the operation that whole V-type bearing need be processed the roller installing space, reduce manufacture difficulty; Carry out paired gusset welding at weldering muscle axle, especially many when gusset weld, increase roller at the V-type bearing of assembly unit, the rotating shaft of realization roller supporting guarantees that gusset departs from the equilbrium position little, during rotation laborsaving.
