Problems solved by technology
It can be seen that when the welding torch moving device of the existing drill pipe wear-resistant band welding machine is used, the lead screw of the ball screw is rotated by hand, which is laborious to operate, and the movement is uneven, which easily leads to the thickness of the welded wear-resistant band. Uneven, poor weld quality

The invention relates to a welding torch moving device for a welding machine with a drill stem wear-resistance belt, which comprises a mounting frame, a ball screw rod and a tubular moving column; a slide rail is arranged on the mounting frame; the screw rod in the ball screw rod is fixedly connected on the mounting frame by a bearing and a bearing seat; the tubular moving column is fixedly connected with a nut in the ball screw rod by a slide block fixedly connected with the tubular moving column; the slide block is connected with the slide rail arranged on the mounting frame; a welding torch is connected on the tubular moving column; one end of the screw rod in the ball screw rod is connected with a stepping motor by a coupling; the stepping motor is fixedly connected on the mounting frame; when in use, the welding torch is connected on the tubular moving column; automatic adjusting is carried out by the stepping motor according to welding width when the wear-resistance belt is welded; the welding torch moving device of the invention is very convenient to be used; besides, the welding of the drill stem wear-resistance belt can be conveniently carried out aiming at the drill stems with different diameters.
Description
technical field [0001] The invention relates to a welding torch moving device of a drill pipe wear-resistant belt welding machine. Background technique [0002] The drill pipe wear-resistant band welding machine is a device for welding the drill pipe wear-resistant band. The drill pipe wear-resistant band is set so that the drill pipe with a length of about 10M will be worn when it rubs against the casing or rock during the drilling process. Less, in order to prolong the service life of the drill pipe, the drill pipe welded with Anke wear-resistant band can not only reduce the wear of the drill pipe itself, but also effectively reduce the wear of the casing. In the current drill pipe wear-resistant band welding machine, the welding torch moving mechanism includes: a mounting frame, a ball screw and a tubular moving column. A slide rail is installed on the mounting frame, and the screw in the ball screw is fixedly connected by a bearing and a bearing seat. On the mounting fr...
