A processing method for the structure of the rear section of the sample frame of a rider bike

Abstract

The invention discloses a machining method of a motorcycle sample frame rear-segment structure. The machining method is characterized in that welding jigs are adopted to locate a lower pipe rear portion segment, an electric device supporting lug, a side cover rear supporting lug, an upper pipe tail segment, a rear reinforcing plate, a seat cushion lock support and a tail cover support; the components mentioned above are welded and fixed through a weld gun, and an upper pipe tail segment pressing mechanism for pressing the upper pipe tail segment is arranged in an upper pipe tail segment locating structure and can be horizontally rotated; and after welding is finished, the upper pipe tail segment pressing mechanism is horizontally rotated outwards to avoid interference, a seat cushion rear support is mounted and located and then is welded and fixed. The machining method has the advantages that the welding assembly process can be simplified, operation is simple, cost is low and trial-manufacturing and adjusting of the motorcycle sample frame rear-segment structure can be facilitated.

Description

Technical field [0001] The invention relates to the field of motorcycle frame processing, in particular to a method for processing the rear section structure of a rider bike sample frame. Background technique [0002] Among motorcycles, riding motorcycles, as a classic model, have the advantages of large power and good long-distance driving performance, which are deeply loved by consumers. At the same time, in the process of motorcycle research and development, it is often necessary to first develop and design sample products and conduct tests to ensure the reliability and practicability of the final product. [0003] In a new riding motorcycle model LF-150-10b, the main structure of the frame includes a head tube. The lower end of the rear side of the head tube is fixedly connected to the front inclined tube extending backward and downward, and the upper end of the rear side of the head tube is fixed. Connect the front end of the main beam tube backwards, bend the rear half of th...

Problems solved by technology

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

Especially because sample production often needs to adjust the installation position and installation angle of some local components, welding fixtures with fixed structures are used for each adjustment, which greatly increases the cost and restricts the expansion of sample research and development
