Centring device for welding upper pads

Abstract

The invention discloses a centring device for welding upper pads. The centring device comprises a flat plate, wherein the flat plate is provided with a longitudinal locating block for limiting a position and a plurality of locating blocks for supporting a beam in parallel; the flat plate is also provided with a plurality of clamping air cylinders with guide rails; the side wall of the beam is clamped by clamping blocks on the clamping air cylinders; a plurality of centring air cylinders are arranged below the beam; upper pads located above the beam are clamped by using the clamping blocks on the centring air cylinders; the flat plate is also provided with a plurality of pairs of guide shaft fixing seats located at two sides of the beam; linear bearings are oppositely arranged in the guide shaft fixing seats; and guide shafts connected with the clamping blocks penetrate through the inner rings of the linear bearings. By using the centring device, the problem that precise centring cannot be realized in the upper pad welding process is solved, operation errors caused in the manual centring and welding processes are avoided, and the quality of a product is improved. Pneumatic clamping and location are adopted, so that the production efficiency is increased, and the labor intensity of an operator is relieved.

Description

technical field [0001] The invention belongs to a welding positioning device, in particular to a welding centering device for an upper cushion block. Background technique [0002] The upper beam body is one of the important parts of the special equipment bracket. Such as Figure 4 As shown, the upper beam body includes a hollow cubic column-shaped beam 4 and a plurality of upper spacers 11 , and the plurality of upper spacers 11 are welded on the outer wall of one side of the beam 4 in parallel. At present, the welding tooling is positioned by one side of the positioning block, which will cause welding deviation of the upper pad during the welding process. [0003] Welding errors in the welding process of multiple upper pads are difficult to eliminate, and the consistency of multiple upper pads after welding is poor, resulting in poor overall quality of the welded upper beam body, high labor intensity for the operator, and low work efficiency . [0004] Therefore, a cente...
