Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] figure 1 It is a schematic diagram of the structure of the workpiece to be welded in the prior art, such as figure 1 As shown, the workpiece to be welded is a thin-walled aluminum alloy frame product with a total length of 2000mm and a width of 900mm; The side becomes the overall large frame, and the outer sides of each part of the overall frame form a bow shape with a smooth transition. Among them, the arc frame 2 is made of six horizontal short arc ...

Abstract

The embodiment of the invention discloses a welding positioning device. The device comprises a bottom plate and a plurality of reinforcing rib plates. The reinforcing rib plates are vertically and fixedly connected to the bearing face of the bottom plate side by side at preset intervals, and the bearing face formed by the upper edges of the reinforcing rib plates is matched with the outer surface of a workpiece to be welded. Wave deformation and bent deformation of the workpiece to be welded during welding are prevented. The device not only can meet the rigidity requirement of a whole frame of the workpiece, but also can meet the position size and use requirements of all components of the workpiece.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a welding positioning device. Background technique [0002] One product is a thin-walled aluminum alloy frame product with a total length of 2000mm and a width of 900mm; the frame consists of two small arc-shaped frames and one linear small frame. Arched and smoothly transitioned. Among them, the arc-shaped small frame is made of six horizontal short-arc plates and two longitudinal 2000mm long angle aluminum tailor-welded; the linear small frame is made of five straight-line short-arc plates and two longitudinal 2000mm long angle aluminum tailor-welded become. The method of welding the three small frames separately first, and then welding the three small frames into a whole large frame, due to the thin wall of the aluminum frame, poor structural rigidity, and the small cross-sectional size of each short arc plate, each small After the frame is welded, bending deformation i...
