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

Abstract

The invention discloses a motorcycle sample frame front section structure machining method. The method is characterized by comprising the steps that a headstock pipe, a front inclined pipe, a main beam pipe front section, a headstock connection board, a direction limiting block, radiator support lugs, two engine front suspension shafts and an oil tank mounting shaft are positioned through a welding clamp, and all the components are welded and fixed at a time through a welding gun, wherein the structure for achieving positioning of the main beam pipe front section is arranged on a member arranged in the front-and-back direction, the rear end of the member is located under the connecting position of a main beam pipe and a connection pipe, and the member can be rotated and adjusted; after welding is completed, the member is rotated and adjusted to be parallel to the connection pipe, the connection pipe is positioned through the structure for achieving positioning of the main beam pipe front section on the member, and then the connection pipe is welded and fixed. The welding assembly procedure can be simplified, and the motorcycle sample frame front section structure machining method has the advantages that operation is easy, the cost is low, the trial-manufacturing and adjustment of the front section of a motorcycle sample are convenient, and the like.

Description

technical field [0001] The invention relates to the field of motorcycle frame processing, in particular to a method for processing the front 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 fixedly...

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
