Problems solved by technology

However, the above two mechanisms have the following disadvantages: ①Rotary scanning is realized by the eccentric sleeve driving the conductive rod to rotate around the axis of the motor. The conductive rod is restrained by welding wire and wires and will not rotate around its own axis, avoiding the twisting of the welding wire and the winding of the cable
However, due to the large weight and unbalance of the eccentric sleeve, it will generate large vibration during rotation, which will affect the stability of the welding process and cause high noise, especially when the scanning amplitude and rotation speed are large, the impact is more serious
② The amplitude of the rot

Example Embodiment

[0011] Example 1, by figure 1 It can be seen that the present invention includes a motor, a carbon brush 3 and a standard gas shielded welding cable. The motor composed of a stator 7 and a rotor 8 is housed in the housing 2. The cable connecting the gas shielded welding cable, the welding wire 9 and the shielding gas pipeline are integrated. The chemical joint 1 is sealed and fixedly mounted on the upper part of the housing 2, the protective gas pipeline communicates with the inner cavity of the sealed housing 2 through the integrated joint 1, and the conductive rod 4 is relatively fixed in the housing 2 through a bearing sleeved on it. The upper end of the conductive rod 4 is in communication with the inner cavity of the housing 2, and the two or three carbon brushes 3 installed in a kinetic cooperation with the conductive rod 4 are in electrical conduction with the integrated joint 1. The conductive rod 4 passes through the motor rotor 8 and connects with The motor rotor 8 is fi...

Example Embodiment

[0012] In the second embodiment, the optical code disk 6 matched with the optical couple 5 is fitted in the middle of the conductive rod 4, so as to realize the digital control of the rotary scanning welding torch. The rest is the same as in Example 1.

Example Embodiment

[0013] In Embodiment 3, the lower end surface of the rotary connector 10 fixed at the lower end of the conductive rod 4 is inclined, so that the conductive nozzle 12 fixed on the lower end of the rotary connector 10 is inclined to the conductive rod 4 by an angle. The rotary scanning amplitude can be adjusted step by step by replacing the rotary connector with different inclined end faces, and the rotary connector can be selected according to different welding processes. The rest is the same as in Examples 1 and 2.

Abstract

A scanning welding torch with electric motor to drive the electric conducting rod to rotate and generate rotary welding arc is disclosed. Said motor is installed in the casing. The integrated adapter for electric cable, welding wire and protecting gas tube is sealed in the upper part of said casing and electrically connected to the carbon brush dynamically fit with the electric conducting rod which passes through and is fixed to the rotor of motor. The lower end of said electric conducting rod is extended outside the bottom of casing and fixed to the electric conducting mouth via rotary joint. Its advantages are simple structure, step regulation, and high performance stability.

Description

Technical field [0001] The invention relates to a welding device, in particular to a scanning welding torch driven to rotate by a motor. Background technique [0002] Scanning welding torch is a kind of mechanical method to make the welding arc swing in the direction perpendicular to the welding process, and the welding torch itself or the conductive rod in the welding torch makes a transverse scanning movement. Existing rotary scanning welding torches all realize the garden cone swing mechanism with the conductive rod as the busbar through spherical bearings, such as the "high-speed rotary arc welding equipment" patented by Japan Steel Tube Co., Ltd. in Chiyoda District, Tokyo, Japan on April 29, 1987 (Application No.: 87103245, Examination Announcement No.: 1008611, Examination Announcement Date: July 4, 1990, Publication / Announcement No.: 1022121, Publication / Announcement Date: November 16, 1988, Authorization Date: October 24, 1990 Japan), it is a rotary arc welding equ...
