The positioning welding fixture structure of the front section of the knight car sample frame

Abstract

The invention discloses a positioning and welding clamp structure of a front part section of a riding type motorcycle sample frame. The positioning and welding clamp structure is characterized by comprising a three-dimensional installing platform, a plurality of installing holes arranged according to the fixed interval in an array manner are formed in the upper surface and the peripheral side surface of the three-dimensional installing platform, the positioning and welding clamp structure of the riding type motorcycle sample frame further comprises a motorcycle head pipe positioning assembly used for positioning a motorcycle head pipe, a direction limiting block positioning assembly used for positioning a direction limiting block, a motorcycle head pipe connecting plate and oil tank installing shaft positioning assembly used for positioning a motorcycle head pipe connecting plate and an oil tank installing shaft, a radiator support lug positioning assembly used for achieving positioning of a radiator support lug, a front inclined pipe and engine front suspension shaft positioning assembly used for positioning a front inclined pipe and an engine front suspension shaft and a main beam pipe front part section and connecting pipe positioning assembly used for sequentially positioning the main beam pipe front part section and a connecting pipe. The welding and assembling procedure can be simplified, and the front part section positioning and welding clamp structure has the beneficial effects that operation is simple, cost is low, and trial production and adjustment of the sample front part section of a riding type motorcycle can be conveniently achieved.

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 section 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 f...

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
