Aluminium alloy deep tube argon arc weld backside residual height grinder

Abstract

The invention relates to an argon arc welding line root reinforcement polishing device of an aluminum alloy deep pipe. The argon arc welding root reinforcement polishing device is characterized in that the middle in a shell, one end of which is provided with an opening, is provided with a limiting platform, a pressure spring is arranged on the limiting platform, and a bearing base is arranged above the pressure spring; the outer surface of the bearing base is in clearance fit with the shell, and the inner periphery of the bearing base is provided with a bearing I; the lower part of a rotating shaft passes through the bearing I and then stretches out of the bottom of the shell, the upper part of the rotating shaft is inserted into a grinding head through a bolt; a pre-limiting block is inserted into the outer periphery of the top of the shell, and the bolt is clamped below the pre-limiting block. The polishing device provided by the invention can enter into the aluminum alloy deep pipe in a flexible shaft drive manner so as to effectively polish a welding line which is far from a pipe port, so that the product quality is guaranteed, and the work efficiency is improved.

Description

technical field [0001] The invention relates to an aluminum alloy deep tube argon arc weld rear reinforcement grinder, which is a device for grinding the back reinforcement of the aluminum alloy deep tube argon arc weld. Background technique [0002] At present, the welding seam grinding of aluminum alloy deep pipes is limited to the position near the pipe mouth, that is, the existing method can only manually use a pneumatic drill or an electric drill to grind the weld back reinforcement near the pipe mouth, while the broken jade is far away from the pipe mouth. The welding seam lacks an effective grinding device, which leads to a large number of aluminum alloy deep pipes being unqualified due to the back reinforcement of the weld seam, and the defects exceed the standard, increasing the repair welding process, and seriously becoming waste products, resulting in a waste of manpower, material resources, and financial resources.
