Abstract

The invention relates to a welding positioner with a heating temperature control device, comprising a base, two supports arranged on the base, half shafts arranged on the supports and a large semicircular gear arranged between the half shafts and meshed with a gear of a speed reducer, wherein the large semicircular gear is fixedly provided with a reduction box; a heating device tray is fixedly arranged above the reduction box; a disk-shaped heating device is fixedly arranged above the heating device tray; the center of the disk-shaped heating device is provided with a hole; the hole is internally provided with a main shaft which is meshed with a gear arranged in the reduction box to drive; a rotating table is movably arranged between the main shaft and the disk-shaped heating device; the outer part of the rotating table is fixedly provided with a heat insulating cover with a gap; a thermoelectric couple is arranged in the heat insulating cover; a rotating frame is arranged below the rotating table and provided with a clamping slot; a pin arranged on the main shaft is arranged in the clamping slot; and therefore, the requirements for the welding preheating temperature and the interlayer temperature of a welding workpiece are met.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a mechanical device suitable for heating and welding the impellers of fans, centrifugal compressors and similar parts in the equipment manufacturing industry, and in particular to a welding positioner with a heating temperature control device. Background technique [0002] The materials of various welded impellers used in fans and centrifugal compressors in the equipment manufacturing industry are mostly medium and low carbon alloy steel and precipitation hardened stainless steel. In order to avoid welding defects such as welding cracks, the shaft disk, wheel cover and blade of the impeller must be preheated before welding and kept warm during welding. The welded impellers of fans and centrifugal compressors are mostly ternary structures, and the welding positions need to be constantly changed during welding. Ordinary welding positioners only have the functions of tilting and turnin...
