The utility model comprises an underframe; the bottom wheels of the underframe are connected with a motor; the utility model is mainly structurally characterized in that upright columns are arranged above the underframe; a cross beam with a horizontal guide rail and a wire feeder is arranged between the space above the two upright columns; a welding torch mechanism is arranged on the horizontal guide rail; a motor on the welding torch mechanism enables the welding torch mechanism to run along the horizontal guide rail through a gear and a rack; and the gas cylinders on the upright columns are respectively provided with overturn worktables.

Description

Gantry welding machine

Technical field:

The utility model relates to the improvement of welder device structure.

Background technology:

Railway freight-car needs the side wall of car body and headwall weld seam are welded in the new system process, and on the traditional handicraft, the weld job of newly making car body side wall and headwall is to adopt welding manually.

But exist labour intensity big, and production efficiency is low, welding quality can not get guaranteeing in addition.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of people's of alleviating manual labor, gantry welding machine that production efficiency is high are provided.

For achieving the above object, the utility model adopts following technical scheme, the utility model comprises underframe, the bottom wheel of underframe links to each other with motor, the top of its structural feature underframe is provided with the column body, be provided with between two column bodies top have cross slide way, the crossbeam of wire-feed motor, cross slide way is provided with welding gun mechanism, the motor in the welding gun mechanism makes welding gun mechanism move along cross slide way by gear, tooth bar; Cylinder on the column body is respectively arranged with the upset workbench.

The beneficial effects of the utility model:

1, production efficiency height:

The utility model can weld automatically to the side wall of lorry body and the weld seam of headwall, just exempts hand labor, has improved productivity ratio greatly; Also avoid simultaneously people's work high above the ground, improved the security of producing;

2, can guarantee welding quality:

The utility model can weld automatically to the side wall of lorry body and the weld seam of headwall, just exempts artificial factor affecting, can guarantee welding quality.

The specific embodiment:

The utility model comprises underframe 1, the bottom wheel 2 of underframe 1 links to each other with motor 19, the top of underframe 1 is provided with column body 10, be provided with between two column body 10 tops have cross slide way 13, the crossbeam 16 of wire-feed motor 20, cross slide way 13 is provided with welding gun mechanism 12, and the motor 11 in the welding gun mechanism 12 makes welding gun mechanism 12 along cross slide way 13 operations by gear, tooth bar 15; Cylinder 4 on the column body 10 is respectively arranged with upset workbench 5.

The piston rod 8 of the cylinder 4 of column body 10 links to each other with the connecting rod 7 of upset workbench 5, and connecting rod 7 links to each other with the axle on the column body 10 6; By the reciprocating motion of the piston rod on the cylinder 48, drive closing or opening of upset workbench 5; Be respectively arranged with lock cylinder 3 and locking piece 18 on the upset workbench 5.

Welding gun mechanism 12 comprises welding gun 22, and welding gun 22 is arranged on the rotating disk 27 of gun rack 23, and gun rack 23 is fixed on the horizontal slide rail 24, and laterally slide rail 24 is arranged on the vertical slide rail 25, and vertical slide rail 25 is arranged on the vertical cylinder 29; The rotating turret 28 of vertical cylinder 29 is arranged on the lateral cylinder 21 of crossbeam 16.The bottom of vertical cylinder 29 is provided with tracking wheel 26; Make the surface of tracking wheel 26 contact welded parts, limit welding gun 22 with the coverage between the welded piece.

Column body 10 sides are provided with staircase 17; Can make things convenient for personnel to crossbeam 16, to keep in repair etc.

Welding machine 9 can be fixed on the column body 10.

Below in conjunction with a description of drawings use of the present utility model:

Processed car body placed between the column body 10 be fixed.Cylinder 4 starts, and makes the 5 upset butt joints of upset workbench, and the people can be in 5 work of upset workbench; Can adjust the position at welding guns 22 places according to the welding needs along cross slide way 13, rotating turret 28, startup lateral cylinder 21, vertical cylinder 29; And then by horizontal slide rail 24 (or vertical slide rail 25), and after rotating disk 27 further adjusts the position at welding guns 22 places, can carry out welding job.
