[0019] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments. Figure 1 As shown in the schematic diagram of the overall structure of a battery box back friction welding tool, it includes a tool base plate 2, and a group of adjacent two side edges of the upper end surface of the tool base plate 2 are each provided with a plurality of positioning blocks 3 to position the battery box body; the inner side of the positioning block 3 is provided with a contour groove 6, and the contour groove 6 is opened on the tool base plate 2; the opposite sides of the two side edges of the positioning block 3 installed on the upper end surface of the tool base plate 2 are each provided with a plurality of movable quick clamps 4, and the movable quick clamp 4 is located at the rear of the battery box body; a box support block 5 is installed on the inner side of the movable quick clamp 4 on one side, and the box support block 5 is located on the tool base plate 2; an avoidance groove 7 is milled on the tool base plate 2, and the avoidance groove 7 is located on the opposite side of the box support block 5.
[0020] Specifically, the tooling bottom plate 2 is rectangular. The four top corners of the tooling bottom plate 2 are all provided with chamfers. The contour groove 6 is elliptical. Figure 3 As shown in the schematic diagram of the overall structure of a movable quick clamp in a friction welding tool for the back of a battery box, the movable quick clamp 4 includes a fixed plate 12 and a connecting rod 10. The upper end surface of the fixed plate 12 is fixedly connected to a limiting block 11, and the limiting block 11 is arranged on the periphery of the connecting rod 10. A fixed block 8 is arranged at the front end of the connecting rod 10 to abut against the battery box body. The fixed block 8 is cylindrical. A handle 9 is hinged at the rear end of the connecting rod 10. A plurality of tooling bases 1 are fixedly arranged at equal distances on the bottom end surface of the tooling base plate 2 to support the height of the tooling base plate 2. An avoidance groove 7 is provided at a positioning block 3 on one side of the tooling base plate 2.
[0021] This embodiment provides a specific structural connection method and workflow for a friction welding tool for the back of a battery box. Figure 2 As shown in the schematic diagram of the overall structure of a battery box back friction welding tool when in use, a battery box back friction welding tool comprises a tool base plate 2, the bottom end surface of the tool base plate 2 is fixedly connected to a tool base 1 to carry the tool base plate 2, and the tool base plate 2 is highly supported to ensure the horizontality of the battery box body on the processing equipment; a plurality of positioning blocks 3 are arranged on the outer periphery of the upper end surface of the tool base plate 2 along one side of the horizontal direction and one side of the vertical direction to position the battery box body, and the battery box body is positioned and limited in the horizontal X-axis direction and the vertical Y-axis direction, which greatly improves the production progress; a contour groove 6 is arranged on one side of the positioning block 3 to avoid the weld seam when the battery box body is welded, and the contour groove 6 is milled on the tool base plate 2, and the contour groove 6 can ensure the horizontality of the battery box body before stir friction welding, and is also conducive to the blind placement of the battery box body in the front and back directions, making the placement operation more convenient and accurate; A number of movable quick clamps 4 are arranged on the opposite sides of the two sides of the positioning block 3 installed on the upper end surface of the tooling base plate 2. The movable quick clamps 4 are located at the rear of the battery box body. The handle 9 of the movable quick clamp 4 provides the battery box body with a tightening force in the X-axis direction and the Y-axis direction, reducing the influence of the vibration generated during the subsequent stir friction welding on the production yield rate; a box support block 5 is installed on the inner side of the movable quick clamp 4 on one side, and the box support block 5 is located on the tooling base plate 2. The box support block 5 plays a supporting role for the inverted battery box body, avoiding the deformation of the battery box body caused by the pressure exerted on the box body by the welding head due to the large size of the battery box body and the long welding stroke during the stir friction welding process; an avoidance groove 7 is milled on the tooling base plate 2, and the avoidance groove 7 is located on the opposite side of the box support block 5. The avoidance groove 7 avoids the plug-in panel of the battery box body, so that the battery box body can be placed horizontally, which plays a fool-proof role.
[0022] Workflow: Insert the plug-in panel of the battery box into the avoidance groove 7, so that the box can be quickly positioned in both the front and back directions; push the outer frame of the battery box in the direction of the positioning block 3, so that the battery box body is close to the positioning block 3. When the battery box body is pushed to the limit position, it means that the battery box body has reached the welding position; manually push the handle 9 of the movable quick clamp 4 to fix the battery box body; when the battery box body is fixed, stir-friction weld the battery box body to the tooling bottom plate 2; after stir-friction welding the battery box body, the installation is completed. Manually pull the handle 9 of the quick movable clamp to cancel the fixation of the battery box body, push the battery box in the opposite direction of the positioning block 3, and loosen and take out the formed battery box body in turn. The battery box body is quickly positioned and placed by installing a positioning block 3 on the tooling base plate 2, and quickly positioned on the horizontal X-axis and Y-axis, effectively avoiding positioning errors caused by manual observation; then the horizontal and vertical positions of the battery box body are finally positioned by the movable quick clamp 4, which not only prevents fools and errors but also enables accurate positioning, greatly improving production speed and quality.
