Embodiment 1

[0048] On the one hand, this embodiment provides a process for processing an electric vehicle body, including the following steps:

[0049] Cutting: cut the pipe and plate according to the processing size to obtain the sheet metal blank;

[0050] Forming: Stamping and bending the sheet metal blank to obtain frame accessories;

[0051] Welding: Welding and connecting the frame parts together to form the car body;

[0052] Grinding: Grinding and smoothing the connection points on the car body;

[0053] Spraying: spraying paint on the surface of the car body;

[0054] Drying: Let the paint dry.

[0055] In this embodiment, the spraying is a spraying primer, and after drying, the paint is baked. Baking paint not only improves the aesthetics, but also enhances the protective effect on the frame and prevents rust.

[0056] In the forming step, the forming of the plate is stretched by a stamping mold, so that the plate is stretched integrally to form the main board and the wall ...

Embodiment 2

[0069] The features of this embodiment that are the same as those of Embodiment 1 will not be described in detail. The features of this embodiment that are different from Embodiment 1 are: Figure 4 As shown, in this embodiment, the caliper 4 adopts an arc-shaped surface, which can be more conveniently adapted to circular pipes. When the caliper 4 is an arc-shaped surface, Figure 4 The lowest point of the shown inner surface is on the level of the surface of the grinding wheel 2, so as to ensure that the surface of the polished pipe is smooth.

[0070] Such as Figure 5 As shown, the clamp of this embodiment adopts claws 8, the middle part of the clamping surface of the claws 8 is arc-shaped, and the two sides are planes. The jaws 8 of this embodiment can make the arc-shaped surface of the middle part contact with the surface of the pipe when clamping a circular pipe, and can make the planes on both sides contact with the pipe when clamping a square pipe, and the contact are...

Abstract

The invention discloses an electric vehicle body machining process and a special grinding tool thereof, and belongs to the technical field of electric vehicle machining. The machining process comprises the following steps that rough shape cutting is carried out, and specifically a pipe and a board are cut according to the machining sizes to obtain sheet metal part blanks; forming is carried out, and specifically stamping and bending are carried out on the sheet metal part blanks to obtain frame accessories; welding is carried out, and specifically the frame accessories are connected together to form a vehicle body through welding; grinding is carried out, and specifically all joints on the vehicle body are polished and leveled; spraying is carried out, and specifically paint is sprayed onthe surface of the vehicle body; and drying is carried out, and specifically the paint is dried. The tool comprises a base, wherein a grinding wheel, calipers and clamps are arranged on the base, thegrinding wheel is fixedly installed on the base through a support, the calipers are fixedly arranged on the two sides of the grinding wheel, the clamps are symmetrically distributed on the outer sidesof the calipers, and the grinding wheel and the clamps can rotate in situ. According to the technical scheme in the embodiment, a frame is more attractive, and the grinding effect is good.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle processing, in particular to an electric vehicle body processing technology and a special grinding tool.
