Background technology
At present, adopt the method for semiautomatic welding jointed tubular workpieces more and more extensive, the general method adopting is first the pipe fitting of two needs welding first to be docked, carry out again spot welding, weld-end fittings is clipped on rotatable parts, finally by hand held gun, carry out the welding of pipe fitting, thereby realize the object of semiautomatic welding jointed tubular workpieces.Adopt in this way, when docking pipe fitting carries out spot welding, owing to being manually to rotate spot welding to pipe fitting, so the concentricity between two weld-end fittings is difficult to be guaranteed.If concentricity has requirement, thereby affect the quality of production, reduced to a certain extent welding efficiency.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of rush-harvesting and rush-planting weld cylinder formula weld-end fittings rotation positioning device is provided, has cancelled and manually rotated spot welding, guaranteed the concentricity between two weld-end fittings.
Rush-harvesting and rush-planting weld cylinder formula weld-end fittings rotation positioning device described in the utility model, comprise workbench and turning cylinder, at workbench, be disposed with from left to right locating support and power transmission shaft bracing frame, it is characterized in that: turning cylinder is arranged on power transmission shaft bracing frame by bearing level, at turning cylinder left end, Workpiece clamping head is installed, its right-hand member is provided with three-jaw chuck, corresponding Workpiece clamping head is provided with workpiece locating mechanism on locating support, workpiece locating mechanism comprises the cylinder of piston rotation, the cylinder body of cylinder is fixed on locating support, the piston rod right-hand member of cylinder is provided with the workpiece locating piece matching with Workpiece clamping head, corresponding turning cylinder is provided with driving mechanism.
Above-mentioned Workpiece clamping head and three-jaw chuck are existing general chuck, are mainly used to workpiece to be fixed.During use, during to the higher pipe fitting welding of concentricity requirement, one of them in two pipe fittings that first needs welded is fixed on Workpiece clamping head, again another one pipe fitting and the pipe fitting fixing are aligned, then start cylinder, by the piston rod on cylinder, drive workpiece locating piece to move right, finally complete the relatively fixing of two weld-end fittings, by driving mechanism, drive turning cylinder to rotate again, thereby drive two pipe fittings to rotate, can carry out welding job; Not high to concentricity requirement, also can first to two pipe fittings, carry out artificial spot welding, then fix by three-jaw chuck, then by driving mechanism, drive turning cylinder to rotate, thereby drive, need the pipe fitting of welding to rotate, can carry out welding job.During application, above-mentioned two job steps can also be carried out simultaneously, enhance productivity.
When implementing, the cylinder of above-mentioned piston rotation also can be selected non-rotary piston-cylinder, and workpiece locating piece is connected with piston rod by location bearing, also can realize spinfunction, but the non-rotary piston-cylinder price of piston rod is very expensive, is generally 3 times of left and right of rotary cylinder.
The utility model, for the pipe fitting blanking after conveniently welding, is provided with charging conduit below described Workpiece clamping head and workpiece locating piece cooperation place, on one side charging conduit is fixed on locating support, another side is fixed on power transmission shaft bracing frame.
Driving mechanism described in the utility model is motor, and motor is arranged on workbench, is the transmission of belt pulley transmission group between motor and turning cylinder.
Tired in order to reduce workman's hand, guarantee welding quality, on described three-jaw chuck right side, be provided with gun rack, gun rack is fixed on workbench.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure.During use, during to the higher pipe fitting welding of concentricity requirement, cancelled and manually rotated spot welding, adopted mechanical type to align, guaranteed the concentricity between two weld-end fittings; Not high to concentricity requirement, can first to two pipe fittings, carry out artificial spot welding, then fix by three-jaw chuck.During application, above-mentioned two job steps can also be carried out simultaneously, enhance productivity.
