Problems solved by technology

[0002] At present, the handrail has a space arc structure with double claws and multiple claws. The spatial positioning is not in place during the welding process, and it cannot be fixed in the three-dimensional direction; the handrail products after welding are fixed on different planes; resulting in failure to install in place with other interfaces during the installation process , and it is easy to cause the handrail products to bear the stress after installation, and it is easy to loosen for a long time, shortening the service life of the handrail products

Abstract

The invention relates to a positioning device for welding a curved-surface three-dimensional handrail, and belongs to the technical field of welding forming. The positioning device comprises a chassis, a bracket rotatably and adjustably connected with the chassis, and a plurality of positioning structures arranged on the bracket, and the handrail can be clamped and fixed by the positioning structures; each of the positioning structures comprises a positioning support arranged on the bracket, a positioning clamping plate arranged on the positioning support, a positioning chuck adjustably connected with the positioning clamping plate and a positioning block arranged on the positioning support; and the handrail is clamped and fixed between the positioning chuck and the positioning block. Thepositioning device for welding the curved-surface three-dimensional handrail provided by the invention is simple in structure and convenient to use, the curved-surface three-dimensional handrail can be fixed, looseness is reduced, and the welding precision and the welding quality are guaranteed.

Description

technical field [0001] The invention relates to a positioning device for welding a curved three-dimensional handrail, which belongs to the technical field of welding and forming. Background technique [0002] At present, the handrail has a space arc structure with double claws and multiple claws. The space positioning is not in place during the welding process, and it cannot be fixed in the three-dimensional direction; the handrail products after welding are fixed on different planes; resulting in failure to install in place with other interfaces during the installation process , And it is easy to cause the handrail products to bear the stress after installation, and it is easy to loosen for a long time, shortening the service life of the handrail products. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a positioning device for welding curved three-dimensional handrails, which has a simpl...
