Part machining device capable of automatically adjusting welding size for whole vehicle manufacturing

Abstract

The invention relates to the technical field of new energy car whole manufacturing, and discloses a part machining device capable of automatically adjusting a welding size for whole vehicle manufacturing. The device comprises a shell, an arc disc is movably connected into the shell, and a rotating frame rotates to enable a welding tool to carry out intermittent up and down moving and approach to apart automatically for fixed-point welding. The phenomenon that due to long-time handhold of the welding tool, a body generates uncomfortableness is avoided, higher work efficiency is achieved, the arc disc rotates to enable an incomplete gear to intermittently rotate by 180 degrees, a power source is provided for subsequent variable-length welding operation, a second rotating disc is rotated, afirst rotating disc rotates to drive a movable strip to carry out left and right moving, the welding tool synchronously moves, according to actual needs, the motion state of the welding tool is changed, the reciprocated motion amplitude of the welding tool is automatically adjusted, a part is subjected to sufficient welding, the welding quality is ensured, different welding lengths can be met, andthe problems that due to a single welding size, operation is not easy are solved.

Description

technical field [0001] The invention relates to the technical field of complete vehicle manufacturing of new energy vehicles, in particular to a part processing device for complete vehicle manufacture that can automatically adjust the welding size. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four types of hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. [0003] In the manufacturing process of new energy vehicles, it is often necessary to weld auto parts. Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics....

AI Technical Summary

Problems solved by technology

At present, when welding, the manual method is generally used. The staff holds the welding torch to weld the parts. Due to the large error of manual operation, the welding position is tilted or the welding degree is not enough. The welding quality is relatively poor, which is not conducive to the follow-up. Processing, holding the welding torch for a long time will increase the burden on the hands, and because the dazzling sparks, molten beads and iron slag sprayed out during the welding process are splashed around, if the protective measures are not implemented properly, direct vision or contact will be harmful. A certain degree of injury occurs to the human body, but the current welding device has a single welding size and cannot perform welding of different sizes. The welding length may be too long or the welding length is not enough, which cannot meet the actual needs.

[0004] Aiming at the deficiencies of the prior art, the present invention provides a part processing device for vehicle manufacturing that can automatically adjust the welding size, which has the advantages of adjustable welding length, better welding quality and convenient operation, and solves the problem of welding length and welding quality. It can automatically close to the parts for fixed-point welding, free your hands, avoid the heavy burden on the hands caused by holding the welding tool for a long time, and cause discomfort to the body. It has higher work efficiency and can be used according to actual needs. Change the motion state of the welding tool, automatically adjust the reciprocating motion range of the welding tool, and fully weld the parts to ensure the welding quality, which can meet different welding lengths and avoid the problem of difficult operation due to single welding size
