The cart for automatic welding of the railway open wagon end wall and the end beam has the advantages that the cart is attractive in appearance, a welding cart walking part is light in weight, and the cart is good in walking stability and suitable for automatic welding of the railway open wagon end wall and the end beam.
Description
Technical field
The utility model relates to truck welding field, refers to particularly a kind of truck headwall and end carriage automatic welding dolly.
Background technology
In rail vehicles manufacture field, need various dissimilar automatic welding equipments, for the efficient welding between the each parts of vehicle.At present, the headwall of railway freight-car C70E (H) and C80B (H) and the long straight weld of side wall have all adopted automatic welding equipment.Its welding equipment mainly adopts welding robot, special welding machine.But, C70E (H), C80B (H) vehicle headwall and end carriage welding adopt semi-automatic MAG welding, due to body construction feature, its welding position is in fillet welding in the overhead position, not only working strength is large in welding process for product, and weldquality is difficult to ensure, being partially welded often appears in weld seam, overlap and the fillet weld size weld defect such as cause not of uniform size; If adopt electroplating equipment wielding machine people or special welding machine to weld, manufacturing cost costliness, maintenance is used not convenient.
Summary of the invention
The purpose of this utility model is exactly that a kind of truck headwall simple in structure and end carriage automatic welding dolly will be provided.
For achieving the above object, the truck headwall that the utility model is designed and end carriage automatic welding dolly, comprise vehicle frame, described vehicle frame has connecting cross beam, described connecting cross beam two ends are provided with the carrying vertical beam of perpendicular layout, described carrying vertical beam two ends backward vertical bending are formed with respectively Top Crossbeam and lower cross arm, the end downward bending of described Top Crossbeam is formed with installing plate, on described installing plate, offer installing hole, in described installing hole, be provided with back shaft, on described back shaft, be provided with can be in welding process along the rolling bearing of headwall cross band traveling; The end of described lower cross arm is provided with welding machine suspension plate.
Further, described back shaft is made up of end face limiting plate, bearing construction section and nut construction section, described rolling bearing is sleeved on bearing construction section also spacing by end face limiting plate, and described nut construction section interts to be fixed in installing hole and by locking nut.
Further, between described locking nut and installing plate, be provided with the elastic washer for preventing from getting loose.
Further, the both sides of described end face limiting plate are provided with the Plane Notch of being convenient to wrench operated.
Further, the flare angle between described Top Crossbeam and installing plate is 98 °.
Compared with prior art, the utility model has the advantage of: designed truck headwall and end carriage automatic welding dolly good looking appearance, and welding tractor running gear is lightweight, carriage walking good stability, is applicable to truck headwall and end fine strain of millet automatic welding.The utility model mainly increases by 2 rolling bearings on welding tractor, by headwall cross band as welding guide rail, in welding process, welding tractor is walked all the time on the cross band of parts, has improved smoothness and the position degree of welding tractor walking, makes welding quality stable and secure.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Truck headwall shown in figure and end carriage automatic welding dolly, comprise vehicle frame 1, vehicle frame 1 has connecting cross beam 1a, connecting cross beam 1a two ends are provided with the carrying vertical beam 1c of perpendicular layout, described carrying vertical beam 1c two ends backward vertical bending are formed with respectively Top Crossbeam 1d and lower cross arm 1e, the end downward bending of Top Crossbeam 1d is formed with installing plate 1g, on installing plate 1g, offer installing hole 1b, in installing hole 1b, be provided with back shaft 2, on back shaft 2, be provided with can be in welding process along the rolling bearing 4 of headwall cross band traveling; The end of lower cross arm 1e is provided with welding machine suspension plate 1f.Particularly, back shaft 2 is made up of end face limiting plate 2a, bearing construction section 2b and nut construction section 2c, rolling bearing 4 is sleeved on that bearing construction section 2b goes up and to pass through end face limiting plate 2a spacing, nut construction section 2c interts in installing hole 1b and passes through locking nut 3 and fix, and is provided with the elastic washer 5 for preventing from getting loose between locking nut 3 and installing plate 1g.The both sides of end face limiting plate 2a are provided with the Plane Notch 2d of being convenient to wrench operated, and the flare angle between Top Crossbeam 1d and installing plate 1g is 98 °.
When use, welding machine is arranged on welding machine suspension plate 1f, walk along weld seam with welding gun, welding tractor rides on the cross band of headwall and moves, by adjusting welding gun chuck and the weld seam angle above welding tractor, make welding gun end welding wire and end fine strain of millet angle keep 45 ± 2 ° of degree, keep 90 ° of degree with direction of advance angle, thereby ensured headwall and end fine strain of millet automatic welding quality.
