Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to an automatic pushing and clamping fixture for a collector for a new energy battery pack. Background Art

[0002] The most important "three electrics" of new energy vehicles include batteries, motors and electronic controls. The battery pack provides stable energy support for the vehicle's driving. Most new energy vehicles on the market are based on lithium iron phosphate batteries, ternary lithium batteries and quaternary lithium batteries. The battery pack releases a lot of heat during the charging and discharging process. In cold winter weather, the battery temperature is too low, which will cause the viscosity of the electrolyte inside the battery, thus reducing the charging and discharging efficiency. In hot summer weather, the battery temperature is generally too high. While the active electrolyte charges and discharges energy efficiently, it also brings about an imbalance in the electrochemical stability of the electrolyte, which leads to spontaneous combustion of the battery pack, endangering the safety of the owner and traffic. Therefore, efficient battery pack temperature control is needed. Management system to ensure that the temperature of the battery is balanced during efficient charging and discharging. Therefore, new energy battery temperature control boards are gradually developed by various automobile manufacturers. The temperature control board can generate both heat and cool. Generally, non-standard collectors are connected to each battery cell to ensure the temperature balance of each battery cell during efficient charging and discharging. In addition, according to the differences in design schemes for the length, width and height of the battery pack by different manufacturers, various collector structures are designed. In order to effectively and quickly process non-standard collectors, it is necessary to design and prepare a special positioning and clamping fixture to improve the rapid processing of such non-standard collectors and improve production and processing accuracy and efficiency.

The supporting positioning block is arranged on a base and is used to support and position the lower end face of the blank. Pushing slide rails cooperating with the pushing sliding block are symmetrically arranged on both sides of the supporting positioning block. A plurality of supporting grids are arranged on the upper end to position the lower end face of the blank or the workpiece. Positioning grooves are arranged between adjacent supporting grids.
