Manufacturing and processing technology for alloy frame of electric automobile

Abstract

The invention relates to a manufacturing and processing technology for an alloy frame of an electric automobile. The manufacturing and processing technology uses frame paint spraying equipment. The frame paint spraying equipment comprises a base, a frame fixing device and a frame paint spraying device, wherein the frame fixing device is arranged in the lower end of the base, and the frame paint spraying device is arranged at the upper end of the base. According to the manufacturing and processing technology, through the design of a simple mechanism, a single driving source drives the alloy frame to be fixedly clamped, and meanwhile, the alloy frame is further driven to ascend to facilitate follow-up paint spraying operation, so that the problems that an existing device usually uses a plurality of driving sources or adopts a strong spring assisting mode to conduct fixed clamping, so that the cost is increased, and meanwhile, the fixation of s spring is very unstable, and the like are solved; and by aiming at the structure of a specific frame, more uniform paint spraying treatment is carried out on longitudinal beams of the specific frame.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a manufacturing process of an electric automobile alloy frame. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Because the impact on the environment is smaller than that of traditional cars, its prospects are widely optimistic. The most basic component of a car is the car frame. The frame is generally composed of longitudinal beams and beams. Its forms mainly include side beam type and middle beam type. The side beam type frame is composed of two longitudinal beams on both sides and several cross beams. The longitudinal beams and cross beams are connected by riveting or welding to form a strong rigid frame. . [0003] There are following problems in the manufacturing process of the al...

AI Technical Summary

Problems solved by technology

[0003] There are following problems in the manufacturing process of the alloy vehicle frame: 1. When the vehicle longitudinal beam is painted, it is often necessary to limit the multiple degrees of freedom of the vehicle frame, but the existing devices often use multiple driving sources or Fixing and clamping with the help of strong springs increases the cost, and at the same time, the fixing of springs is also very unstable; 2. Since the longitudinal beams of automobiles often have a certain track and are not completely horizontal, it is necessary to design for a specific structure Stringer undergoes painting work
