Problems solved by technology

Although the frame rear body assembly is composed of the above five parts, in actual welding, due to its three-dimensional special-shaped structure, the clamping and positioning of each part before welding is very troublesome, not only the positioning efficiency is low, but also the positioning accuracy is not high. Affect the final molding quality

Abstract

The invention discloses a motorcycle frame rear body assembly welding jig. The motorcycle frame rear body assembly welding jig is characterized in that a lower bottom plate is provided with a left half body assembly positioning mechanism, a right half body assembly positioning mechanism, a fuel tank rear mounting bracket component positioning mechanism, a left and right connecting plate positioning mechanism, and a seat lock mounting bracket component positioning mechanism; the left half body assembly positioning mechanism and the right half body assembly positioning mechanism are symmetrically arranged; an upper front bottom plate and an upper rear bottom plate are respectively arranged on the two sides of the lower bottom plate through support structures; a certain space is reserved between the upper front bottom plate and the upper rear bottom plate, so that a left half body assembly support pipe and a right half body assembly support pipe can pass in a downwardly inclined manner. The motorcycle frame rear body assembly welding jig provided by the invention has the advantages that clamp positioning of all parts of a motorcycle frame rear body assembly is integrated, so that the jig structure is simplified, fewer clamp positioning points and rapid clamping are achieved, accordingly, the product loading / unloading time for the jig is shortened, and the welding efficiency is improved; meanwhile, the positioning of all the parts is more accurate and precise, and the assembly positioning requirements are better met, so that the forming quality of the welded frame rear body assembly is higher.

Description

technical field [0001] The invention relates to a welding jig for a motorcycle frame, in particular to a welding jig for a rear body assembly of a motorcycle frame, and belongs to the technical field of jigs. Background technique [0002] The motorcycle frame is one of the core components of the motorcycle, supporting the weight of the body, rider and all cargo, and undertaking an important safety function. The structure of the motorcycle frame is very complicated. It is welded by many metal pipes to form a three-dimensional structure. According to the actual installation needs, many functional lugs and metal plates are welded. Motorcycle frames are almost all formed by welding, so many welding fixtures are designed for welding. The main body of the welding fixture is a positioning mechanism for positioning the welding parts and a quick clamping mechanism for pressing the welding parts to prevent loosening. When welding, first place the parts to be welded in the fixture a...
