Embodiment Construction

[0030] The structure and working principle of a non-polar eccentric rotating arc welding torch suitable for welding will be further described in detail below.

[0031] Such as figure 1 As shown, the steplessly adjustable eccentric rotating arc welding torch is composed of a frame 18, a hollow shaft motor 1, a rotating sleeve, a fixed bearing sleeve 10, and a feed system. Wherein the rotating sleeve is composed of three parts, namely an upper sleeve 4 , a middle sleeve 6 and a lower sleeve 8 . Wherein the eccentric platform is made up of the center ball bearing 16, the center ball bearing sleeve 14, the eccentric adjustment motor 5, the ball bearing 20, the bevel gear 7, the polished rod 19 and the screw mandrel 15, and the center bearing 13 is formed. The feed system includes a conductive plate 22 , a carbon spring brush 23 , a flexible cable 24 , an insulating washer 25 , a conductive rod 12 , and a conductive tip 11 .

Abstract

A rotary arc welding torch with stepless adjustment of eccentricity and an adjustment method thereof. The welding torch includes a frame with a bottom plate and a top plate. The bottom plate and the top plate of the frame are respectively opened with a through hole whose center lines deviate from each other. The plane on the top plate is equipped with a hollow shaft motor through the through hole, and the plane on the bottom plate is fixedly installed with a hollow motor. The fixed bearing sleeve of the shaft motor coaxial line, the longitudinal section of the fixed bearing sleeve is U-shaped, and there is a mounting hole off the axis at the bottom, and the lower deep groove ball bearing and the rotating sleeve are embedded in the fixed bearing sleeve from outside to inside. The upper end of the rotating sleeve is connected with the output shaft of the hollow shaft motor through a set screw, and an eccentric adjustment device is installed in the middle to clamp one end of the conductive rod, and the other end of the conductive rod passes through the mounting hole of the fixed bearing sleeve and the through hole of the bottom plate. The outer circle of the end is equipped with a spring carbon brush, and the end is connected with a conductive tip. The invention realizes the stepless adjustment of the radius of rotation, reduces the relevant noise during the operation of the welding torch, and has simple structure and stable performance.

Description

technical field [0001] The invention relates to a welding torch, more specifically to a rotary arc welding torch for stepless adjustment of eccentricity suitable for welding, and belongs to the field of welding technology. Background technique [0002] Rotary arc welding has the advantages of high production efficiency, low welding cost, and low energy consumption, and is widely used in the welding of medium and thick plates. The rotary arc is to make the welding wire or the conductive rod rotate around an axis. Nowadays, there are many researchers who study the narrow gap GMAW of the rotary arc, but there are two main ways to realize the rotary arc welding torch. One is through the conical swing of the conductive rod. , and the other is realized by means of eccentric conductive tip. The main representative institutions of conical swing are: the high-speed rotary arc welding equipment designed by Japan Steel Tube Co., Ltd. (CN87103245A), which adopts the conical swing type....
