Positioning welding fixture structure for the front part of the rear beam tube of the frame for the sample of the bent beam vehicle

Abstract

The invention discloses a frame rear beam tube front positioning welding clamp structure used for a cub-type motorcycle sample. The frame rear beam tube front positioning welding clamp structure is characterized by comprising a rear upper beam tube front positioning assembly, an oil tank front support positioning assembly, a seat cushion support positioning assembly and a rear lower beam tube front positioning assembly. The rear upper beam tube front positioning assembly is used for positioning the front of a rear upper beam tube, the oil tank front support positioning assembly is used for positioning an oil tank front support, the seat cushion support positioning assembly is used for positioning a seat cushion support, and the rear lower beam tube front positioning assembly is used for positioning the front of a rear beam tube. The frame rear beam tube front positioning welding clamp structure is simple, reliable in positioning and capable of simplifying the welding assembly process and has the advantages of being easy to operate, low in cost, capable of facilitating trial-manufacture adjusting of the cub-type motorcycle sample and the like.

Description

technical field [0001] The invention relates to the field of motorcycle frame processing, in particular to a positioning welding jig structure for the front part of the rear beam tube of the frame for the curved beam vehicle sample. Background technique [0002] The curved beam motorcycle refers to the motorcycle type in which the main beam of the motorcycle in front of the seat cushion is bent from the right front to the rear to form a downward gap in front of the seat cushion. Underbone motorcycles are the most common motorcycles nowadays. Among the motorcycle family, its durability, simple operation and other characteristics are deeply loved by consumers. As an economical and practical vehicle, the underbone motorcycle has become a popular vehicle suitable for various consumer groups. At the same time, in the process of motorcycle research and development, it is often necessary to develop and design sample products first, and then conduct tests to ensure the reliability ...

Problems solved by technology

Like this, there are many working procedures, complicated operation, and the defects that the cost is too high

In particular, the production of samples often requires the adjustment of small structures such as some local auxiliary components. In this way, welding fixtures with fixed structures are used for each adjustment, which greatly increases the cost and restricts the expansion of sample research and development.
