Manufacturing method of light-weight aluminum alloy battery bracket of new energy automobile

Abstract

The invention relates to the field of welding, in particular to a manufacturing method of a light-weight aluminum alloy battery support of a new energy automobile. The method comprises the following steps of: reconstructing a three-dimensional model of an aluminum alloy battery bracket and a three-dimensional model of a skin based on a design drawing of the light-weight aluminum alloy battery bracket; based on the three-dimensional model of the battery bracket and the three-dimensional model of the skin, obtaining corresponding three-dimensional mold parameters of the aluminum alloy battery bracket and three-dimensional mold parameters of the skin; manufacturing an aluminum alloy battery bracket mold and a skin three-dimensional mold based on the aluminum alloy battery bracket three-dimensional mold parameters and the skin three-dimensional mold parameters; manufacturing the aluminum alloy battery bracket and the skin, wherein the matched clamping structure is arranged between the aluminum alloy battery bracket and the skin which are in butt joint; and assembling and fixing the aluminum alloy battery bracket and the skin, and welding along the seam of the aluminum alloy battery bracket assembly. According to the invention, the situation of skin deformation is avoided as much as possible, the strength of the welding seam can be remarkably improved, and the repair rate is reduced.

Description

technical field [0001] The invention relates to the field of welding, in particular to a method for manufacturing a lightweight aluminum alloy battery bracket for a new energy vehicle. Background technique [0002] With the rapid development of electric vehicle technology, the development of power batteries has reached the bottleneck stage, and it is difficult to greatly increase the cruising range of vehicles through breakthrough technological innovations. Therefore, many manufacturers have begun to focus on the research direction of body weight reduction. In order to keep the center of gravity of the vehicle body low, the power battery is often placed in the middle of the bottom of the vehicle. The battery bracket is a structure for carrying the power battery, which is very important for the safety of new energy vehicles. At present, the existing battery bracket generally adopts a set of keels on the inside and outside of the skin, the outer keel is used to protect the bat...
