technical field

Tooling such as water-cooled plates for new energy vehicles, water-cooled plates, electricity and battery coolers are important components of the battery cooling system of new energy vehicles and an important component of the thermal management system of new energy vehicles. Among them, the water cooling plate is an important part of the cooling system. When clamping the water-cooled plate tooling, due to the various sizes of the water-cooled plate tooling, in order to suit the size of each tooling, the clamping tooling is either made into manual clamping, or the clamping device is replaced as a whole to improve compatibility. However, manual clamping tooling is time-consuming and labor-intensive, and the production efficiency is low.
