In recent years, new energy electric vehicles gradually replace fuel automobiles, and become an increasingly growing automobile type. The power battery in an electric vehicle is a storage component of its electric energy, which is a core component in the whole vehicle. The power battery module is carried by a battery tray, and the battery tray is connected with a vehicle chassis to form a firm carrying vehicle body. Because the weight of the new energy electric vehicle is closely related to the endurance mileage of the new energy electric vehicle, and because the weight of the vehicle body is reduced, the aluminum frame structure is excellent due to the light weight, corrosion resistance, recovery residual value and other comprehensive indexes, the new energy electric vehicle becomes a choice for more and more new energy automobiles, and the battery tray is used as an important structural component of the new energy electric vehicle, and the aluminum alloy material is not used for processing and manufacturing.
The existing part of aluminum alloy battery tray is manufactured by aluminum alloy, aluminum alloy sections form a battery tray longitudinal and transverse frame bearing structure, aluminum alloy thin bottom plates are paved at the bottoms of the trays, and the edges of the thin bottom plates are required to be spot welded with the aluminum sections so as to ensure tight connection between the thin bottom plates and the aluminum section frames and form a sealed and smooth connection surface. During the previous spot welding operation: firstly, putting the frame on a tooling table, then laying a thin bottom plate on the frame, clamping a plurality of clamps on the tooling table, most of the clamps are pneumatic quick clamps, a single pressure head is arranged on the quick clamp, the edge of the thin bottom plate is tightly pressed on the frame, and a welding gun of a welding robot mechanical arm stretches into a gap between the clamps to carry out spot welding. The existing spot welding tool has the following defects: 1. because the plane area of the battery tray is large, the number of welding spots required between the frame and the thin bottom plate is as large as tens, if each welding spot is ensured to be fixedly compressed by the pressure heads on two sides during welding, the whole battery tray is required to be provided with the pneumatic pressure heads with corresponding number, the whole spot welding tooling table is crowded in position and complicated in pipeline, and the tooling table is high in cost; 2. in the compression welding process of the pressure head, the thickness of the thin bottom plate is only 1-2mm, so that the defects of deformation, wrinkling and the like still occur, and the flatness of the battery tray is affected; 3. because the welding spot is actually the recooling solidification of the molten metal, the shape of the welding spot and the flowing trend of the molten metal welding spot to the periphery cannot be completely controlled, if the distance between the welding spot and the pressure head is too short, welding adhesion is easily caused, and if the distance between the welding spot and the pressure head is too long, a good flattening welding effect cannot be achieved.

The pressing strip is in the form of a pressing strip A, one side of the pressing strip A close to a welding point is provided with a plurality of door-shaped half grooves, and the positions of the half grooves are matched with the positions of the welding point. When the welding robot welding gun is used for spot welding at the lap joint, the formed welding spot is positioned at the concave position of the portal semi-groove, and cannot contact with the pressing strip A, so that the welding spot is prevented from being contacted and adhered with the pressing strip, and the operation of equipment is influenced.
The pressing strip is in the form of a pressing strip B, one side, close to a welding point, of the pressing strip B is provided with a plurality of through grooves, and the positions of the through grooves are matched with the positions of the welding point. When the welding robot welding gun is used for spot welding at the lap joint position, the formed welding spot is positioned at the through groove position and cannot contact the pressing strip B, so that the welding spot and the pressing strip are prevented from being contacted and adhered, and the operation of equipment is prevented from being influenced. In addition, the welding gun of the robot stretches downwards from the through groove, and the welding gun is also suitable for the situation that other parts of the battery tray are too close to the lap joint.
The lower end of the frame is provided with a plurality of leveling foot cups and a plurality of anchor bolt mounting plates. When the machine frame is installed, the clamping groove of the installation plate is clamped into the embedded foundation bolt, then the leveling foot cup is adjusted to enable the machine frame to be horizontal, and finally the foundation bolt is fastened with the foundation bolt installation plate through nuts, so that the installation, the fixation and the leveling of the tool machine frame are completed.
And a plurality of positioning pins are arranged on the upper end face of the edge of the frame and are matched with the positions of the process holes in the aluminum profile frame of the battery tray. The position of the aluminum profile frame placed in the tool is always kept consistent and not offset.
The intelligent clamping and yielding general tool for welding the square aluminum product bottom plate comprises the following steps:
(1) Placing the welded battery tray bottom frame on a table surface of a tool, wherein the process holes are matched with positioning pins of the tool, and the number of the positioning pins is more than or equal to 2;
(2) Placing the thin base plate on the bottom frame;
(3) The operator installs a button on the operation table, so that all cylinders drive the pressing bars of the pressing device to press down, and the edges of the thin bottom plate are lapped and pressed with the aluminum profile;
(4) The welding robot performs spot welding fixation on preset positions on the lap joints one by one according to a preset program, and the spot welding positions are matched with the half groove or the through groove positions of the pressing strips;
(5) After the welding is finished, the pressing bar rises, the battery tray is taken out, and the welding operation is finished.
The utility model has the advantages that:
1. the utility model is specially used for spot welding operation at the lap joint of the bottom plate and the frame of the battery tray, and the pressing bar can be pressed and welded close to the welding point, so that the defects of deformation, wrinkling and the like generated during welding of the bottom plate of the battery tray are reduced.
