Problems solved by technology

[0002] At present, the traditional welding method of welding the V-shaped annular seam between the cylinder barrel and the cylinder body and the corner seam between the cylinder body and the flange is still a manual welding process, so the welding quality is poor
The specific manifestations are: uneven weld width, impermeable weld, pores, pits, slag inclusions, easy burn through, low welding tensile strength and other defects

Embodiment Construction

[0012] As attached figure 1 As shown, the welding voltage, current and air pressure control of each layer of the workpiece 36 to be welded are preset by the encoder, the number of welding turns, the automatic lifting of the welding gun 11 between layers, and the circumferential welding speed of the workpiece 36 to be welded driven by the frequency conversion motor 3; 22 drives the swing speed of the welding torch 13 swing device; the lifting cylinder 8 drives the automatic, manual and semi-automatic of the welding torch 11 up and down; the automatic, manual and semi-automatic data programs of the pneumatic tailstock 15 tightening and loosening and input in the PLC programmable controller 1 in. Clamp the workpiece 36 to be welded on the three-jaw chuck 5 and click on the tightening program of the pneumatic tailstock 15 in the touch screen 4, so that the axis of the workpiece 36 to be welded is placed on the axis of the three-jaw chuck 5 and the pneumatic tailstock 15 Heart conne...

Abstract

The invention relates to a program-controlled side-moving oil cylinder circumferential seam welding machine, which consists of seven parts: an automatic control system, a power clamping mechanism, a lateral shifting device, a vertical lifting device, a welding torch swinging device, a position fine-tuning device and a welding mechanism. The invention adopts a PLC programmable controller as a main control unit, and adopts a Chinese display and video touch screen as a parameter adjustment dialogue interface. The touch screen can set the welding voltage, current welding speed and swing speed of each layer, and it is equipped with automatic and manual buttons for welding torch up and down. The invention adopts the mode of rotating the workpiece and fixing the welding torch; the welding torch is equipped with a fine-tuning mechanism and a two-axis angle adjustment device, which can adjust different welding angles; the welding torch is controlled by air pressure, and the micro DC motor drives the welding torch to swing; the tailstock is tightened by air pressure, and the machine head The three-jaw clamping method is adopted to realize automatic, manual and semi-automatic operation. The invention has the advantages of high degree of automation, good welding quality, safety and reliability.

Description

Technical field [0001] The invention relates to a welding machine, in particular to a welding machine for automatically welding the V-shaped annular seam between the cylinder barrel and the cylinder degree and the corner seam between the cylinder body and the flange, and belongs to the field of numerical control welding machine manufacturing. Background technique [0002] At present, the traditional welding method of welding the V-shaped annular seam between the cylinder barrel and the cylinder degree and the corner seam between the cylinder body and the flange still uses a manual welding process, so the welding quality is poor. The specific manifestations are: uneven weld width, impermeable welding, porosity, pits, slag inclusion, easy burn through, low welding tensile strength and other defects. With the continuous deepening of scientific and technological progress, the traditional manual welding process has been far behind the development needs of the times. People are eager t...
