Abstract

The invention relates to a locating device for pipe fitting welding, and belongs to the technical field of rotary locating design of welded pipe fittings. The locating device for pipe fitting welding comprises a workbench and a rotary shaft, wherein a locating support and transmission shaft supporting frames are arranged on the workbench from left to right in sequence, the rotary shaft is horizontally installed on the transmission shaft supporting frames through bearings, a workpiece chuck is installed at the left end of the rotary shaft, and a three-jaw chuck is installed at the right end of the rotary shaft; a workpiece locating mechanism is installed on the locating support, corresponds to the workpiece chuck, and comprises a lead screw and a nut, wherein the lead screw and the nut are matched with each other, the nut is fixed on the locating support, and a workpiece locating block which is matched with the workpiece chuck is installed at the right end of the lead screw through a locating bearing; a motor is arranged corresponding to the rotary shaft. By the adoption of the locating device, when pipe fitting welding with the requirement for high concentricity is conducted, the mode of manual rotating spot welding is cancelled, mechanical alignment is adopted, and concentricity of the two welded pipe fittings is ensured.

Description

Pipe fitting welding positioner
Technical field
The present invention and a kind of pipe fitting welding positioner, 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 pipe fitting welding positioner, eliminate and manually carry out rotation spot welding, ensure that the concentricity between two weld-end fittings.
Pipe fitting welding positioner 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 screw mandrel and screw that cooperatively interact, screw is fixed on locating support, screw mandrel right-hand member is provided with the Workpiece fixing block matched with Workpiece clamping head by location bearing, corresponding turning cylinder is provided with motor, motor is installed on the table, it is the transmission of gear drive group between motor and turning cylinder.
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 that fixes are aligned, then rotary screw rod, under the cooperation of screw mandrel and screw, drive Workpiece fixing block to move right, finally complete the relatively fixing of two weld-end fittings, rotated by driven by motor turning cylinder 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 be rotated by driven by motor turning cylinder, 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.
Conveniently use, reduce labour intensity, at described screw mandrel left end, handle chassis is installed.
In order to reduce workman's hand fatigue, guaranteeing welding quality, on the right side of described three-jaw chuck, being provided with gear wheel, gear wheel is fixing on the table.
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, enhance productivity.
