[0026] In this embodiment, a garbage truck loading body side panel robot welding tool is installed on an external machine as shown in Fig. 9 As shown, it includes positioners 1 on both sides, an electric docking clamping mechanism 6 connected to the two positioners, a side panel fixing frame 3 located on a three-point positioning seat 2 of the electric docking clamping mechanism, a plurality of quick clamps 4 and a screw disc clamp 5 installed on the guide rail of the side panel fixing frame.

[0027] The process of using a garbage truck loading body side panel robot welding tooling in this embodiment is as follows:

[0028] 1) Install the side panel on the side panel fixing frame 3. The operator calibrates the side panel to make it close to the guide rails 3-4 and 3-3 and the positioning holes on the side panel match the positions of the clamps. Use the quick clamps 4-1, 4-2 and 4-3 and the screw disc clamp 5 to quickly fix the side panel.

[0029] 2) If Fig. 9 As shown, the positioner 1 and the electric docking clamping mechanism 6 are connected vertically on the ground by bolt fastening, the three-point positioning fixture 2 is respectively installed and connected to the three-point support of the electric docking clamping mechanism 6, and the side plate fixing frame 3 with the side plate installed is transported to the three-point positioning seat of the electric docking clamping mechanism 6, so that the conical head of the three-point positioning fixture 2 and the three conical holes of the connecting seat 3-1 on the side plate fixing frame 3 are matched with each other. As long as the upper end face (minor diameter) of the conical head is included in the range of the lower end face (major diameter) of the conical hole, the standard of mutual matching between the two is achieved, and at the same time, the difficulty of the matching docking is low, and the docking error is easy to offset. The bottom positioning seat 2-3 of the three-point positioning fixture 2 plays a limiting role, and the conical hole of the bottom plate 3-1-3 cooperates with the conical head of the bottom positioning seat 2-3; the motor 6-1 drives the transmission shaft 6-2 to rotate and drives a pair of left and right clamping seats 2-1, 2-2 to move relative to each other, the conical head 2-1-1 of the left clamping seat 2-1 cooperates with the conical hole 3-1-1-1 of the vertical plate 3-1-1, and the conical head 2-2-1 of the right clamping seat 2-2 cooperates with the conical hole 3-1-2-1 of the vertical plate 3-1-2, and the left and right clamping seats 2-1, 2-2 can clamp the side plate fixing frame 3 horizontally and fix it.

[0030] 3) After fixation, the robot first welds the weld on the front side panel; then the positioner 1 works, and the flipping motors 1-4 drive the electric docking clamping mechanism 2 and the side panel fixing frame 3 equipped with the side panel to perform axial flipping at the same time, and the robot then welds the weld on the back side panel; the positioner 1 works and rotates again to make the side panel fixing frame 3 in the initial clamping state.

[0031] 4) After welding is completed, the clamping seats 2-1 and 2-2 on the left and right sides of the three-point positioning fixture 2 are moved outward to loosen the conical head, and the side panel fixing frame 3 with the welded side panel is lifted and transported away.

[0032] 5) Reset the quick clamp and screw disc clamp on the side panel fixing frame 3, release the fixation of the side panel, lift the side panel away with a crane, and carry out the next side panel assembly operation.

[0033] Obviously, in addition to the displacement mechanism 1 and a pair of electric docking clamping mechanisms 6 in the above-mentioned embodiment, the external machine may also adopt other existing mechanical equipment, as long as the three-point positioning fixture 2 and the side panel fixing frame 3 can be installed to rotate and a pair of clamping seats can be moved linearly relative to each other.

[0034] The present invention is not limited to the above-mentioned embodiments, and any technical solutions formed by equivalent replacement shall fall within the protection scope required by the present invention.
