Description
Technical field
The present invention relates to welding equipment manufacturing technology field, especially a kind of equipment for frame crossbeam welding.
Background technology
The frame cross of automobile is one of important parts of automobile; Have a kind of frame cross, this frame cross has transverse tube and is located at respectively the multiple connector on this transverse tube.At present, the welding of this frame cross is to be undertaken by a reverse welding device, and this reverse welding device comprises frame and is erected at the rollover stand that is provided with handle in described frame, at described rollover stand, is provided with holder.During welding, first frame cross is contained on the rollover stand of reverse welding device, rotate rollover stand by each connector on transverse tube one by one spot welding be positioned at the assigned address of transverse tube, then rotate rollover stand by operator, one by one each connector is welded on transverse tube.This by operator, by rotating the welding manner of rollover stand, there are the following problems in process of production: 1, because the spot welding location of each connector of frame cross and welding are entirely by operator's manual operations, craftsmanship is required high, cost of labor is high; 2, during spot welding, need manually to use holder to be fixedly clamped to welded connector, after the weld seam welding that completes connector one side, need manually turn to the welding that correct position carries out other seam welderings of connector, inefficiency not only, and welding quality is unstable, more especially need to rotate the arc-shaped slit weldering of rollover stand welding simultaneously; 3, operator works for a long time under the environment of strong arc light radiation, easily health is damaged.
Summary of the invention
The object of this invention is to provide a kind of frame cross welding workstation, to solve the low and unsettled problem of welding quality of existing frame cross production efficiency.
In order to address the above problem, the technical solution used in the present invention is: plant frame cross welding workstation and include reverse welding device, described reverse welding device has a plurality of, a plurality of described reverse welding devices be located at be fixed with welding robot erecting bed around, described reverse welding device all has frame and is located at the rollover stand being driven by overturning drive device in described frame, described rollover stand consists of bedplate and the side plate that is connected to these bedplate two ends, two end seats that are provided with axle head keeper that driven by the first power cylinder are housed on the bedplate of described rollover stand, a plurality of positioning seats that are provided with pressure head that driven by the second power cylinder are housed between two described end seats, top at described positioning seat is provided with detent, described pressure head is provided with the locating piece corresponding with the detent of described positioning seat in bottom.
In the technical scheme of above-mentioned frame cross welding workstation, technical scheme can also be more specifically: described axle head keeper comprises geometrical clamp and the live splint being hinged on respectively on described end seat, one end of described geometrical clamp is hinged on one end of described the first power cylinder, and one end of described live splint is hinged on the piston rod of the described first power cylinder other end; Described pressure head is hinged on described positioning seat, and one end of described pressure head is hinged on the piston rod of described the second power cylinder.
Further, described overturning drive device comprises the driving headstock being connected with described rollover stand one end side plate by drive plate and the driven headstock being connected with described rollover stand other end side plate by clutch plate, described driving headstock comprises the trip shaft that is provided with drive plate, one end at described trip shaft is provided with gear, the tooth bar being connected with a joggle by slide rail and described gear is housed in described driving headstock, and described tooth bar is connected with the 3rd power cylinder.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, because rollover stand is driven and overturn by the rack-and-pinion kinematic pair with the 3rd power cylinder driving, can, according to the welding position requirement of frame cross, adjust the flip angle of rollover stand; Simultaneously respectively axle head keeper and the positioning seat that is provided with pressure head by various connector stationary positioned to be welded on the transverse tube of frame cross, by welding robot, can carry out continuous welding to various connectors, guarantee the stable of weld seam welding quality; 2, welding operates by welding robot, can weld the frame cross on a plurality of reverse welding devices simultaneously, less demanding to operator's technical ability, only need 1 general work to replace original 3 welding skilled workers to do my work and use, improve production efficiency, reduced production cost; 3, operator only need be responsible for the clamping of workpiece, has avoided strong arc light radiation, guarantees that produced on-site personnel health preserves from.
