Description

Automatic welding machine for circular seam

Technical field

The utility model relates to a kind of welding equipment, is specifically related to a kind of automatic welding machine for circular seam.

Background technology

Cylindrical storage filling, large diameter steel pipe class welding structural element, the welding job amount is very big in manufacturing process, and its weld seam all has certain rules, is advisable to adopt automatic weldering.Existing automatic welder(welding machine), build is huge, complex structure, purchase cost and use cost are very high, and medium-sized and small enterprises are difficult to bear.Still manually to be welded as the master, not only labour intensity is big in medium-sized and small enterprises, and is difficult to guarantee welding quality, also is difficult to increase work efficiency.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned deficiency, provide a kind of simple in structure, cost of manufacture is low is suitable for the automatic welding machine for circular seam that medium-sized and small enterprises use.

In order to solve the problems of the technologies described above, the utility model provides a kind of automatic welding machine for circular seam of following structure, this welding machine comprises base, affixed door shaped stent on the base, the guide rail of affixed vertical setting on two columns of door shaped stent, slidely connect the weldering arm support on the guide rail, affixed weldering arm on the weldering arm support, slidely connect the slippage frame and be rotatably connected to the horizontal leading screw that is spirally connected with the slippage frame on the weldering arm, the affixed wire-feed motor that has welding torch on the slippage frame, laterally leading screw be packed in the traversing motor power that welds on the arm support and be connected; Be provided with the support that is fixed on the base between two columns of door shaped stent, be rotatably connected to anchor clamps on the support, anchor clamps are connected with clamp motor power, and affixed lifting motor on the crossbeam of door shaped stent, motor power are connected with the elevating screw that drives the lifting of weldering arm support; This welding machine also comprises electrical control cubicles and electric welding machine, and wire-feed motor, electric welding machine, traversing motor, clamp motor and lifting motor are electrically connected with electrical control cubicles.

The automatic welding machine for circular seam of said structure, just weldering arm, anchor clamps and relevant power set are combined with support with affixed door shaped stent thereon by a base, the lifting of weldering arm and the simple and reliable leading screw that moves through of wire-feed motor drive, therefore, automatic welding machine for circular seam provided by the utility model, have advantage simple in structure, that cost of manufacture is low, be particularly suitable for medium-sized and small enterprises and use.This welding machine can also bring speed of welding fast, and quality is good, the benefit that labour intensity is low.

In order to make welded piece more stable, be connected with roller rack on the base, be rotatably connected to carrying roller on the roller rack.
