A ring seat automatic positioning welding device

Abstract

The invention discloses a ring-base automatic positioning and welding device. The ring-base automatic positioning and welding device comprises an upper electrode, an upper electrode base, an upper electrode tip, an intense magnet, a lower electrode, a lower electrode base, a lower electrode taper sleeved, a lower electrode tip, an isolated support, a clamp bottom plate, a support screw, an isolated pad, a working cylinder, a wedge head, a guiding rack, oblique blocks, rocker arms, positioning and clamping heads, a long pin shaft, a reset spring and connection rods. The ring-base automatic positioning and welding device has the beneficial effects that the working cylinder which is synchronous with projection welding is adopted for pushing the oblique blocks, so that the two positioning and clamping heads synchronously move toward the center under the effect of the rocker arms; a connection ring is clamped, and then is welded; the workpiece is prevented from being deflecting, and is always at a welding central position; an automatic positioning mode is adopted, so that the problem that positioning is inaccurate, and thus the center of the workpiece can be hardly maintained on the welding position all the time caused by workpiece width tolerance is eliminated.

Description

technical field [0001] The invention relates to the field of welding, in particular to an automatic positioning welding device for ring seats. Background technique [0002] In the past, when the connecting ring and the connecting seat were welded, the method of putting the ring into a slotted hole or using the arc surface was used. The positioning rotation was skewed due to the ring width tolerance and the unstable forming radius of the arc surface, and it was difficult to achieve compliance. Symmetry required. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and provides an automatic positioning welding device for ring seats. The present invention adopts an automatic positioning method, which eliminates the offset of the center caused by the width tolerance of the ring and no longer uses the mutual positioning method. The positioning of the connecting ring and the connecting seat is no longer affected by the arc surfac...
