Description

Technical Field

[0001] The utility model belongs to the technical field of welding devices, and more specifically, relates to a welding device for an electric bicycle frame. Background Art

[0002] An electric bicycle is a means of transportation similar to a traditional bicycle. It combines human power and electric assistance. It usually consists of a bicycle frame with pedals and an electric drive system. Riders can choose pure human power or assisted electric drive mode as needed to make riding easier and more comfortable. The electric bicycle frame is the main structural framework of the electric bicycle. It is mainly made of various metal or alloy materials. It supports and connects the various components to provide a stable riding experience and provide good handling and comfort under various road conditions. The electric bicycle frame is generally composed of scattered parts that need to be connected together, which requires welding equipment.

[0003] When welding bicycle frames, existing welding devices usually use a clamp to fix the frame and then use a welding gun to weld the frame joints. In actual production, this method only has one fixed clamp. During the process of fixing and removing the frame from the clamp, the welding gun cannot continue to weld other frames. In other words, it is impossible to continuously weld multiple sets of frames, resulting in low production efficiency. Therefore, in view of this, research and improvement are conducted to address the existing structure and shortcomings, and provide a power-assisted bicycle frame welding device to achieve a more practical and valuable purpose.
