DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely further describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-2 As shown, a tool for turning over and transporting relatively large arc-shaped thin-walled body-in-white parts is composed of a translation mechanism, a lifting mechanism and a lifting device mechanism.

[0017] The translation mechanism is provided with an Ω beam 5, which is connected to the lifting mechanism through a pulley 6. The translation mechanism is also provided with slide rails 7 installed on both sides thereof. The slide rails 7 are installed on connecting rods 9 through slide rail connectors 8. The connecting rods 9 are installed on both sides of the Ω beam 5 through fixings 10 to realize free translation of the sling.

[0018] The lifting mechanism is lifted by an electric hoist 11 and is installed on the Ω beam 5 through a pulley 6. It can be controlled by one hand using a remote control of the electric hoist 11 and can be moved forward, backward, left and right. The bottom of the lifting mechanism is connected to the main frame 1 through at least one connecting piece 12.

[0019] The lifting device mechanism consists of a main frame 1, a vacuum suction cup 2, and a pneumatic swing table 3. The main frame 1 is welded from thin-walled square tubes. The vacuum suction cup 2 is installed on the output end of the pneumatic swing table 3 through a support frame 4. The double pneumatic swing table 3 is used to drive the workpiece to flip. According to the outer size of the front piece, it is selected to grab from the outside of the front piece. The rotation center line passes through the center of gravity of the front piece. Before sucking the workpiece, the vacuum suction cup 2 and the support frame 4 are vertically downward. After sucking the front piece, they can rotate freely to realize the grabbing and release of the front piece of the top cover.

[0020] The method of using the utility model is as follows: the production personnel grab the workpiece through the lifting device mechanism, lift the front piece through the lifting device mechanism, rotate the front piece to a lying position through the pneumatic swing table 3, and then manually guide it to the welding tooling for welding operations. The lifting device mechanism is not removed during this process. After welding is completed, the lifting is continued and manually pulled to the front piece assembly storage rack, and the pneumatic swing table 3 is rotated to a vertical state, and the workpiece is placed on the rack. After releasing the vacuum lifter, press the rotation lock button to rotate the vacuum suction cup 2 and its support frame 4 to a vertical state and lock them.

[0021] The present utility model is not limited to the above-mentioned implementation modes, and anyone should be aware of the structural changes made under the inspiration of the present utility model. Any technical solutions that are the same or similar to the present utility model fall within the protection scope of the present utility model.

[0022] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
