Welding tool fixture for power battery base

Abstract

The invention discloses a welding tool fixture for a power battery base. The welding tool fixture comprises a positioning mechanism used for positioning and fixing for a weldment, a pressing mechanism arranged on the positioning mechanism and used for applying pressing force to the weldment, and an electronic control system used for controlling the positioning mechanism and the pressing mechanism to achieve the process of positioning, fixing and pressing. The electronic control system controls the positioning mechanism to conduct fast and accurate positioning and fixing and postwelding release for the weldment and to enable the weldment to eject out of an assembling section according to a preset program. The electronic control system controls the pressing mechanism to fast press and release the weldment in a linkage mode, manual participation is not needed, and automation of the whole working process is achieved through executive components of the mechanisms under the control of the electronic control system. The welding tool fixture for the power battery base has the advantages of being fast in action, high in efficiency and simple and convenient to operate. Automation replaces the manual repeated heavy work in the previous manual weldment clamping process.

Description

technical field [0001] The invention relates to the field of welding tool technology, in particular to a welding tool fixture for a power battery base of a new energy vehicle. Background technique [0002] In the composition of the vehicle power battery, the battery base is used as a mechanical part to carry the weight of the battery module, and the battery module is installed on the vehicle body, and the battery base is mostly a metal component. [0003] During the welding process of the battery base, the weldment needs to be positioned and fixed before the welding process can be carried out; in the process of positioning and fixing the weldment, the weldment was assembled manually in the past, and the positioning, clamping and Repeated and heavy work such as turning over, the labor intensity of the operator is very high, and the production efficiency is low. The existing welding problems in this situation are: due to the inaccurate and reliable positioning and clamping of...

Problems solved by technology

[0003] During the welding process of the battery base, the weldment needs to be positioned and fixed before the welding process can be carried out; in the process of positioning and fixing the weldment, the weldment was assembled manually in the past, and the positioning, clamping and Repeated and heavy work such as turning over, the labor intensity of the operator is very high, and the production efficiency is low

The existing welding problems in this situation are: due to the inaccurate and reliable positioning and clamping of the welding parts before welding, welding deformation is easy to occur, and the process defects are obvious; moreover, it does not meet the requirements of automation and high-efficiency development in modern production
