Description

Technical Field

[0001] The utility model particularly relates to a welding tool for a new energy battery vehicle-mounted frame. Background Art

[0002] The battery rack is a relatively important component of the battery components in new energy vehicles. Its main structure includes a frame and a number of steel plate structures welded on the frame for installing, isolating and protecting the battery. Therefore, welding the battery rack is an important link in the production of battery components. However, during the production process, since the battery rack needs to be kept from shaking during welding, the battery rack needs to be positioned during the welding process to increase the accuracy of the welding. However, due to the large number of mounting structures and complex geometric shapes on the battery rack, it is difficult to use a processing method or tooling to handle the welded battery rack in a way that not only can position it firmly, but also does not affect the welding operation and does not occupy the welding operation surface.

[0003] To solve the above problems, Chinese patent announcement number CN219443982U discloses a welding tool for a new energy battery vehicle carrier, which discloses a battery rack end positioning mechanism arranged at intervals on both sides; the battery rack end positioning mechanism includes a U-shaped loading seat, and the two sides of the top of the U-shaped loading seat are respectively assembled and connected with sliding column components, and the positioning components are assembled and connected between the sliding column components; the positioning component includes a positioning frame seat, and the central part of the positioning frame seat has a rectangular through hole, and a plurality of contact rod components are assembled and connected in the rectangular through hole, and the contact rod component includes a horizontal screw threaded in the rectangular through hole, and the horizontal screw is vertically threaded with a vertical screw, and the bottom of the vertical screw is fixedly connected with a hexagonal contact; the left and right sides of the U-shaped loading seat are respectively fixedly connected with a drooping seat, and a horizontal screw is assembled and connected between the drooping seats, and an end seat plate is fixedly connected between the ends of the horizontal screw, and an angle adjustment mechanism is assembled and connected on the end seat plate, and a side limit plate is slidably connected between the drooping seats, and a plurality of side positioning screws are threaded on the side limit plate. The inner end of the side positioning screw is fixedly connected with a hexagonal positioning convex head.

[0004] In summary, the existing new energy battery vehicle-mounted rack welding tooling is too cumbersome for the clamping, positioning and installation of the battery rack. In particular, the side positioning uses multiple side positioning screws to achieve multiple resistance supports on the sides of the battery rack to ensure that there is no welding offset in the left and right directions. However, using the above method, each time the battery rack is installed and disassembled, the side positioning screws need to be screwed one by one to complete the installation and disassembly of the battery rack. The installation and disassembly process is cumbersome and cannot meet production needs. Utility Model Content
