Description

Technical Field

[0001] The utility model relates to a positioning tooling, specifically a positioning tooling for fixing the connection plug of a power battery pack, belonging to the technical field of fixing tooling. Background Art

[0002] The power supply of new energy vehicles is usually realized by a battery pack. When installing the battery pack, multiple batteries and end plates are first packaged into a battery module. The end plate is provided with mounting holes for bolts, and a step forming a screw hole is arranged in the box body. After placing the battery module in the box body, bolts are passed through the mounting holes on the end plate and the screw holes on the step and tightened to install the battery pack.

[0003] The box body of the battery installation box is provided with a mounting groove for mounting the connection plug, and mounting holes are formed at the four corners of the mounting groove. Currently, the connection plug is placed in the mounting groove, and then bolts are used to fix the connection plug in the mounting hole with an electric screwdriver. During the process of the electric screwdriver screwing the bolts, since there is no fixing device for the connection plug, when the first bolt is driven, the entire connection plug will shake or even run out of position. It is necessary for an operator to hold the connection plug with one hand and hold the electric screwdriver with the other hand to fix the bolt. It is rather laborious for a single worker to complete, and in actual production, there have been multiple alarms in the airtightness test of the entire battery pack in subsequent workstations. After investigation, the leakage points are all at the connection plug here, and it is obvious to the naked eye that the connection plug is installed obliquely, which is confirmed to be a personnel installation quality problem. At the same time, the battery installation box is prone to deformation under the impact of the electric screwdriver, which will also affect the product quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve a series of problems brought about by the shaking or even running out of position of the connection plug during the process of the electric screwdriver screwing the bolts in the prior art, and provide a positioning tooling for fixing the connection plug of a power battery pack.
