Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a special alignment tooling for battery pack housings. Background Technology

[0002] Currently, new energy is a major trend in the global automotive industry's transformation, upgrading, and green development. Lightweight chassis is an inevitable choice for energy conservation and emission reduction. However, battery pack housing castings are highly susceptible to deformation during casting and transportation, and the deformation trends of each part are inconsistent, making detection and identification extremely difficult. When transferred to the machining process, deformed products exhibit issues such as misaligned holes and lack of shine during processing, affecting processing efficiency and wasting processing costs. Existing technology relies on manual hammering, which uses insufficient force to induce plastic deformation in chassis parts, resulting only in elastic deformation. This is unsuitable for straightening, and the battery pack housing has numerous bending points, making overall straightening impossible. Utility Model Content

The central alignment cylinders are installed in the middle of the base plate through cylinder brackets. The diagonal alignment cylinders are installed on the base plate through cylinder brackets. A pair of horizontal alignment cylinders are installed at the ends of the base plate through cylinder brackets.

[0005] The support block is an L-shaped support block.

[0006] The pressure plate is detachably mounted on the pressure plate support block by bolts.

[0007] Both the central alignment cylinder and the diagonal alignment cylinder have C-shaped support seats.

[0008] The piston rod end of the diagonal alignment cylinder is equipped with an alignment hook.

[0009] The piston rod end of the central alignment cylinder is equipped with an alignment hook.
