A processing method for the structure of the middle section of the test frame of a rider bike

Abstract

The invention discloses a method for machining a frame middle segment structure of a motorcycle sample. The method comprises the steps that a welding clamp is firstly adopted for locating an engine suspension mounting rack, an engine rear upper suspension shaft, an engine rear lower suspension shaft, a flat fork shaft, a sided cover lock supporting lug, a storage battery supporting lug, a front reinforcement block, an upper pipe front segment, a lower pipe front segment and a side cover lower supporting lug; then a welding gun is adopted for completing welding and fixing of the components at a time, after welding is completed, a compressing mechanism of the upper pipe front segment is horizontally rotated outward to avoid interference, then an air filter supporting lug locating plate used for achieving locating of an air filter support is mounted, the front side face of the air filter support is located through an air filter support locating plate, and then welding and fixing of the air filter support are completed. According to the method, welding and assembling procedures can be simplified, and the method has the beneficial effects that operation is easy, cost is low, and trial-manufacturing and adjusting of the middle segment of the motorcycle sample 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 middle section structure of a rider bike sample frame. Background technique [0002] Among the motorcycles, riding motorcycles, as a classic model, have the advantages of high power and good long-distance driving performance, and are deeply loved by consumers. 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 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 front end of the main beam tube is connected backwards, the second half of the main beam tube is bent downward along the middle position and connected to the engine suspension mounting frame at the rear end, the rear middle of the head tube is fixedl...

AI Technical Summary

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

Especially when the middle part of the frame is welded and processed, the above-mentioned problems and defects are particularly prominent
