Abstract

The invention discloses a rapid positioning mechanism for stud welding of a battery pack shell. A mechanism body with a handle is arranged, the mechanism body is connected with a positioning pin blockand a front block, and the front block is connected with a stud positioning block and a handheld mechanism body through a connecting block, a main positioning pin and an auxiliary positioning pin ofthe positioning pin block are inserted into the positioning holes of a lower shell inner cross beam to be positioned, after positioning is completed, the stud welding position of the lower shell innercross beam is located at the stud positioning block, then welding is conducted, the handle is handheld to take out the mechanism after welding, operation is convenient, studs can be rapidly positioned and accurately welded, and the rapid positioning mechanism is suitable for production.

Description

technical field [0001] The invention relates to the field of battery pack casings, in particular to a rapid positioning mechanism for welding nut columns of the battery pack casing. Background technique [0002] The battery pack shell is one of the main parts of the new energy vehicle battery pack. Its structure is generally a half-pack shell, with an internal distribution frame structure. The grounding wire is required inside. This grounding wire is connected with the nuts inside the shell. For connection, the nut posts need to be welded on the beam inside the battery pack case. At present, it is impossible to quickly and accurately find the welding position for nut stand welding, and the operation is complicated and inconvenient, which cannot meet the needs of production. Therefore, it is necessary to solve this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fast positioning mechanism for welding the n...
