Rotary double-station positioning machine for welding

Abstract

The invention relates to a rotary double-station positioning machine for welding. The rotary double-station positioning machine for welding comprises a U-shaped support and supporting shafts, wherein the supporting shafts are fixed on the upper part and the lower part of the U-shaped support; axes of the supporting shafts are superposed; a lifting ring which are matched with the two supporting shafts through bearings respectively is arranged in a U-shaped recess formed in the U-shaped support; a motor, a speed reducer and a driving gear are mounted at the bottom of the lifting ring; the speed reducer is fixed on the motor; the driving gear is mounted on the speed reducer; a driven gear which is engaged with the driving gear is arranged on the upper part of the lower supporting shaft; a supporting table is mounted at the upper end of the upper supporting shaft; and a two-degree-of-freedom adjusting device is mounted at the upper end of the supporting table and is in sliding fit with the lifting ring. The rotary double-station positioning machine for welding has the advantages of reasonable structural design, high automation degree, high control precision and the like. Free switching of double stations in a welding process is realized, a two-degree-of-freedom position adjusting function is fulfilled, and therefore, requirements of welding of different workpieces are met.

Description

technical field [0001] The invention relates to the technical field of welding machinery, in particular to a rotary double-station positioner for welding. Background technique [0002] During the welding process, welding processing is usually carried out for different positions of the same workpiece, and welding positioners are often used for assistance. However, traditional welding positioners are mostly single-degree-of-freedom motion adjustments, and the rest of the orientation adjustments require With the help of the multi-degree-of-freedom operation of the welding robot, on the one hand, the equipment cost of the robot is high. On the other hand, the programming of the robot is complicated, and the robot is huge. When welding at different positions, the movement of the welding robot itself is time-consuming. It is also longer, which affects the efficiency of the welding process. Contents of the invention [0003] Aiming at the defects of the above-mentioned technolog...
