Description
Technical field
The present invention relates to a kind of blanking type rush-harvesting and rush-planting weld-end fittings localization machine, belong to the rotational positioning design field of weld-end fittings.
Background technology
At present, adopt the method for semiautomatic welding jointed tubular workpieces more and more extensive, the method of general employing first needs the pipe fitting of welding first to dock by two, carry out spot welding again, weld-end fittings is clipped on rotatable parts, carry out the welding of pipe fitting finally by hand held gun, thus realize the object of semiautomatic welding jointed tubular workpieces.Adopt in this way, when docking pipe fitting and carrying out spot welding, owing to being manually carry out rotation spot welding to pipe fitting, so the concentricity between two weld-end fittings is difficult to be guaranteed.If concentricity has requirement, thus affect the quality of production, reduce welding efficiency to a certain extent.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of blanking type rush-harvesting and rush-planting weld-end fittings localization machine, eliminate and manually carry out rotation spot welding, ensure that the concentricity between two weld-end fittings.
Blanking type rush-harvesting and rush-planting weld-end fittings localization machine of the present invention, comprise workbench and turning cylinder, locating support and power transmission shaft bracing frame is disposed with from left to right at workbench, 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 that piston rotates, the cylinder body of cylinder is fixed on locating support, the piston rod right-hand member of cylinder is provided with the Workpiece fixing block matched with Workpiece clamping head, corresponding turning cylinder is provided with actuating unit, the below of Workpiece clamping head and Workpiece fixing block cooperation place is provided with charging conduit, charging conduit is while be fixed on locating support, another side is fixed on power transmission shaft bracing frame.
Above-mentioned Workpiece clamping head and three-jaw chuck are existing general chuck, are mainly used to be fixed workpiece.During use, during to the pipe fitting welding that concentricity requirement is higher, first one of them needs in two pipe fittings of welding is fixed on Workpiece clamping head, again another one pipe fitting and the pipe fitting fixed are aligned, then start cylinder, drive Workpiece fixing block to move right by the piston rod on cylinder, finally complete the relatively fixing of two weld-end fittings, drive turning cylinder to rotate by actuating unit again, thus drive two pipe fittings to rotate, can welding job be carried out; Not high to concentricity requirement, also first can carry out artificial spot welding to two pipe fittings, then be fixed by three-jaw chuck, then drive turning cylinder to rotate by actuating unit, thus drive the pipe fitting needing welding to rotate, can welding job be carried out.During application, above-mentioned two job steps can also be carried out simultaneously, enhance productivity.
When implementing, the cylinder that above-mentioned piston rotates also can select non-rotary piston-cylinder, and Workpiece fixing block is connected with piston rod by location bearing, also can realize spinfunction, but piston rod non-rotary piston-cylinder price is very expensive, is generally about 3 times of rotary cylinder.
Further, described actuating unit is that motor is installed on the table, is the transmission of gear drive group between motor and turning cylinder.
Wherein, preferred described gear drive group comprises gear wheel and pinion, gear wheel) to install on the rotating shaft, pinion is arranged on the motor shaft of motor.
Further preferred described motor is servomotor.
Compared with prior art, the present invention has following beneficial effect:
By the present invention, its structure is simple.During use, during to the pipe fitting welding that concentricity requirement is higher, eliminate and manually carry out rotation spot welding, adopt mechanical type to align, ensure that the concentricity between two weld-end fittings; Not high to concentricity requirement, first can carry out artificial spot welding to two pipe fittings, then be fixed by three-jaw chuck.During application, above-mentioned two job steps can also be carried out simultaneously, and the pipe fitting blanking after convenient welding, enhances productivity.
