Cell box frame CMT welding fixture for electric car

Abstract

The invention relates to a cell box frame CMT welding fixture for an electric car. The cell box frame CMT welding fixture comprises a mounting seat, a horizontal reversing shaft, a horizontal steering seat and a rotary table. Corner clamping devices are arranged at the corners of the rotary table, side directional clamping devices are arranged on both the left and the right side surfaces of the rotary table, and front limiting blocks are arranged on the outer sides of both the front and the rear ends of the rotary table correspondingly; and inner clamping devices are arranged on the inner sides of both the front and the rear ends of the rotary table correspondingly, a main clamping device used for clamping a main cross beam extending left and right is arranged at the top of the rotary table, and an auxiliary clamping device used for clamping an auxiliary cross beam extending front and back is arranged at the top of the rotary table. According to the cell box frame CMT welding fixture for the electric car, through arrangement of the corner clamping devices at the corners of the rotary table, the side directional clamping devices are arranged on the side surfaces of the rotary table, the inner clamping devices are arranged on the inner sides of both the front and the rear ends of the rotary table, the main clamping device is arranged at the top of the rotary table, and the auxiliary clamping device is arranged at the top of the rotary table; and clamping is convenient to conduct on the multiple positions of a cell box, and when a welding head is welded, each clamping device can loosen and abdicate and does not influence the precision of other components to cell box limiting.

Description

technical field [0001] The invention relates to the technical field of automobile battery box production equipment, in particular to a CMT welding jig for a battery box frame of an electric vehicle. Background technique [0002] As the main force of new energy vehicles, electric vehicles are becoming more and more popular in today's increasingly serious environmental pollution. Electric vehicles usually use batteries as the energy supply for vehicles, so electric vehicles are equipped with a large number of battery packs. Due to the center of gravity of the whole vehicle and the heat dissipation of the battery pack, the battery pack is usually placed at the bottom of the vehicle and placed in a flat battery box. Usually the battery box is assembled and welded by a frame and criss-cross beams. The existing argon arc Welding is very easy to burn through the battery box, so CMT welding is usually used. The existing CMT welding method is fully automatic, so automatic high-precis...

[0002] As the main force of new energy vehicles, electric vehicles are becoming more and more popular in today's increasingly serious environmental pollution. Electric vehicles usually use batteries as the energy supply for vehicles, so electric vehicles are equipped with a large number of battery packs. Due to the center of gravity of the whole vehicle and the heat dissipation of the battery pack, the battery pack is usually placed at the bottom of the vehicle and placed in a flat battery box. Usually the battery box is assembled and welded by a frame and criss-cross beams. The existing argon arc Welding is very easy to burn through the battery box, so CMT welding is usually used. The existing CMT welding method is fully automatic, so automatic high-precision clamping fixtures are required
