Fixture structure for positional welding of the rear part of the rear beam tube of the frame for the sample of the curved beam vehicle

Abstract

The invention discloses a clamp structure for a fixed-position welding of a rear portion of a rear beam of a frame of a cub-type motorcycle sample. The clamp structure is characterized by comprising a rear lower beam pipe rear locating assembly, a rear damping shaft and rear damping shaft support lug locating assembly, an oil tank rear support locating assembly and a motor body covering part support lug locating assembly. The rear lower beam pipe rear locating assembly is used for locating the rear portion of a rear lower beam pipe. The rear damping shaft and rear damping shaft support lug locating assembly is used for locating a rear damping shaft and a rear damping shaft support lug. The oil tank rear support locating assembly is used for locating an oil tank rear support. The motor body covering part support lug locating assembly is used for locating a motor body covering part support lug. The clamp structure is simple, reliable in locating and capable of simplifying the welding assembly process. The clamp structure has the beneficial effects of being easy to operate, low in cost, capable of facilitating trial-production and adjustment 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 fixture structure for the rear part of the rear beam tube of the frame for bending beam vehicle samples. 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 classes. 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 reliabilit...

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.
