Example Embodiment

[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 portal-type automatic computer oil-cylinder welder which comprises seven parts, namely an automatic control system, a dynamic clamping mechanism, a lateral moving device, a vertical lifting device, a welding gun swinging device, a position fine-tuning device and a welding mechanism. A PLC (Programmable Logic Controller) serves as a master control unit; a Chinese character display touch screen serves as a parameter-adjusting session interface; the touch screen is used for setting a welding voltage, a current welding speed and a swinging speed for each layer and is provided with an automatic and manual button for lifting a welding gun; a mode of workpiece rotation and welding gun fixation is adopted in the welder provided by the invention; the welding gun is provided with a fine-tuning mechanism and a double-axis angle adjusting device, so that different welding angles can be adjusted; the welding gun is lifted under the control of air pressure; a micro direct-current motor is used for driving the welding gun to swing; a tail base is tightly jacked by the air pressure; and a welder head is held by three claws, thereby realizing automatic, manual and semi-automatic operations. The portal-type automatic computer oil-cylinder welder has the advantages of high automation degree, high welding quality, safety, reliability, and the like.

Description

technical field [0001] The invention relates to a welding machine, in particular to a welding machine for automatically welding a V-shaped annular seam between a cylinder barrel and a cylinder body and a corner seam between a cylinder body and a flange, and belongs to the field of numerically controlled 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 body 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: defects such as uneven weld width, impermeable welding, pores, pits, slag inclusions, easy burn-through, and low welding tensile strength. 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 to have...
