DETAILED DESCRIPTION

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0042] like Figures 1 to 6 As shown, a turning device of the utility model comprises:

[0043] Rack 1;

[0044] The rotating assembly 2 is arranged on the frame 1, and the rotating assembly 2 comprises a first rotating member 3 rotatably arranged on the frame 1 and a swing arm 4 drivingly connected to the first rotating member 3. When the first rotating member 3 rotates on the frame 1, it is used to drive the swing arm 4 to rotate on the frame 1;

[0045] A fixing assembly 5, which is fixed on the swing arm 4, and is used to fix the workpiece on the swing arm 4. When the swing arm 4 rotates on the frame 1, it is used to drive the workpiece to flip on the frame 1;

[0046] The lifting assembly 6 is arranged on the frame 1 and below the rotating assembly 2. The lifting assembly 6 is used to drive the workpiece to rise or fall in the vertical direction.

[0047] During operation, the fixing component 5 fixes the workpiece on the swing arm 4, and the first rotating member 3 drives the swing arm 4 to rotate on the frame 1, thereby driving the workpiece fixed on the swing arm 4 to flip on the frame 1. At the same time, the lifting component 6 drives the workpiece to rise or fall in the vertical direction, so that the swing arm 4 can better flip the workpiece to the production line. This method of flipping the workpiece does not require lifting a heavy workpiece, so that the safety of this work is greatly guaranteed.

[0048] The rotating assembly 2 also includes:

[0049] A worm gear is provided with a first fixing seat 7 on the frame 1, and the worm gear is arranged in the first fixing seat 7;
