A method for processing the structure of the front section of the scooter sample frame

Abstract

The invention discloses a machining method for the structure of a front section of a sample frame of a scooter. The machining method is characterized din that a welding clamp is used for completing clamping and fixing among a headstock pipe, the front end of a lower beam pipe, an ignition switch lock support, a meter housing support and a direction lock block; a welding gun is used for welding and fixing the parts; a positioning assembly used for clamping and positioning the ignition switch lock support and the meter housing support is demounted so as to prevent interference; a positioning assembly used for clamping and positioning a radiator grille installation pipe and a radiator grille installation supporting lug is well installed in the welding clamp so that the radiator grille installation pipe and the radiator grille installation supporting lug can be clamped and positioned; and then the welding gun is used for completing welding between the radiator grille installation pipe and the headstock pipe and welding between the radiator grille installation pipe and the radiator grille installation supporting lug. The machining method has the advantages that welding and assembling processes can be simplified, operation is simple, cost is low, and trial-manufacture and adjusting of the front section of the sample frame of the scooter can be conducted conveniently.

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 scooter sample frame. Background technique [0002] A scooter is a vehicle between a motorcycle and a car, and it is a popular means of transportation. The shape and size of the scooter is similar to that of a motorcycle, the difference is that there is a recessed pedal between the head and the body seat for the driver's feet, and its transmission system generally adopts continuously variable speed, so there is no need to change gears when driving. Especially suitable for ladies riding. Like motorcycles, during the research and development process of scooters, it is also necessary to develop and design sample products first, and conduct tests to ensure the reliability and practicability of the final product. [0003] In a new scooter model LF-125-T, the main structure of the frame includes a cylindrical head tub...

Problems solved by technology

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

At the same time, because sample production often requires adjustments to the installation positions and installation angles 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 in the front section of the vehicle frame, due to the large number of additional components and different positions, the above-mentioned problems and defects are particularly prominent during welding.
