Clamping and rounding device

Abstract

The invention relates to a clamping and rounding device. The clamping and rounding device comprises a rack, a travelling frame, a travelling driving piece, a telescopic piece and lower clamping mechanisms, wherein the travelling frame is arranged on the rack; the lower clamping mechanisms comprise a plurality of sliding mechanisms and universal couplings, the adjacent sliding mechanisms are connected through the universal couplings, and the sliding mechanisms and the universal couplings form an annular structure; the sliding mechanisms comprise connecting bases, jacking pieces, racks and gears, rotating shafts are arranged on the connecting bases, the gears are fixed to the racks, the jacking pieces are connected with the racks, and the jacking pieces and the racks are movably connected tothe connecting bases; the movable end of the telescopic piece is connected with the racks, the telescopic piece can drive the jacking pieces and the racks to move in the radial directions of the lower clamping mechanisms, and the gears are meshed with the racks; and the two ends of the rotating shafts are connected with connecting shafts of the universal couplings on the two sides of the slidingmechanisms correspondingly. The invention provides the clamping and rounding device capable of guaranteeing the roundness of a stirring barrel and the manual blade placement precision, and capable ofeffectively improving the placement welding efficiency of blades inside the stirring barrel.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a circle embracing device. Background technique [0002] When the internal blades of the cement mixing tank are placed and welded, the traditional process is that the workers place the tailor-welded mixing tank on the long-axis roller frame using KBK, and pick the blades required for this type of mixing tank and place them at the rear cone of the mixing tank. , the welder puts the blade on top according to the blade spiral line drawn in advance, and two workers cooperate to weld and fix the blade. After the blade is welded, it is lifted to the next station by KBK. [0003] Because the longest mixing tank is 7.3 meters and the maximum diameter is 2.3 meters, it is all made of 3.5mm steel plate coiled and welded. Using the above method, the mixing tank is easily deformed due to the influence of gravity during welding, the roundness is difficult to ensure the accuracy of blade pla...
