Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

A turnover welding platform as shown in figures 1-4 mainly comprises a first support frame 1, a second support frame 2 and a cross beam frame 3. Wherein the first support frame 1 and the second support frame 2 are arranged oppositely, and the cross beam frame 3 is connected to the lower parts of the first support frame 1 and the second support frame 2. The first support frame 1 and the second support frame 2 are both in an A shape. The top of the first support frame 1 is provided with a first support table 11, and the first support table 11 is provided with a first bearing seat 12 and a first connecting shaft 13 matched with the first bearing seat 12. The first connecting shaft 13 is arranged in parallel to the length direction of the beam frame 3, one end of the first connecting shaft 13 is provided with a first mounting frame 14 for connecting the welding jig, and the other end is provided with a gear 15. The first supporting table 11 is provided with a rack 16 meshed with the gear 15, the first supporting table 11 is further provided with a cylinder 17 driving the rack 16 to translate, and a cylinder rod of the cylinder 17 stretches and retracts to drive the first connecting shaft 13 to rotate, so that the first mounting frame 14 is further turned. The second support frame 2 is provided with a second support table 21, the second support table 21 is provided with a second bearing seat 22, and the second bearing seat 22 is provided with a second connecting shaft 23 in a matching manner. The second connecting shaft 23 is coaxial with the first connecting shaft 13, and the overturning action driven by the air cylinder 17 can be completed through the connection of the welding fixture. The second connecting shaft 23 is provided with a flange 24, and the flange 24 is provided with a second mounting frame 25 for connecting a welding clamp. The flange 24 is further provided with an extension arm 26, the extension arm 26 is arranged along the radial direction of the flange 24, and the second support platforms 21 on the left and right sides of the flange 24 are respectively provided with a stop block 27 for blocking the extension arm 26 and a first position sensor 28, which are used for limiting the rotation angle of the flange 24, so as to control the turning range of the welding fixture. The first position sensor 28 transmits the rotation-in-place signal to the welding robot to realize the robot cooperative welding.

In order to keep the appearance clean and protect the moving parts, a cover 18 is arranged on the first supporting table 11 to surround the gear 15, the rack 16 and the lever of the air cylinder 17 on the first supporting table 11.
