DETAILED DESCRIPTION OF THE INVENTION

(5) In the following, the details and working conditions of a specific device provided by the present invention are described in combination with the figures.

(6) The fixture is composed of a stand 1, a cross plate 2, a turnover air cylinder 3, a servo motor 4, a flip plate 5, a guide rail I 6, a sliding plate 7, left bearing seats 8, left shafts 9, left clamping blocks 10, a clamping air cylinder 11, right bearing seats 12, right shafts 13, right clamping blocks 14, a connecting rod 15, a sliding block 16 and a guide rail II 17. The cross plate 2 is fixed on the stand 1; the sliding block 16 is fixed above the cross plate 2 through the guide rail II 17, and an output rod of the turnover air cylinder 3, which is fixed above the cross plate 2 in a similar way, is connected with the sliding block 16; two ends of the connecting rod 15 are respectively hinged with the sliding block 16 and the flip plate 5; the right side of the flip plate 5 is hinged with the stand 1; the sliding plate 7 above which two left bearing seats 8 are fixed are connected with the flip plate 5 through the guide rail I 6; two left shafts 9 of which upper ends are respectively fixed with the left clamping blocks 10 are fixed inside the left bearing seats 8 through the bearing; the servo motor 4 is fixed below the sliding plate 7, and an output end of the servo motor 4 is connected with one of the left shafts 9; the clamping air cylinder 11 is fixed above the flip plate 5, and an output end of the clamping air cylinder 11 is connected with the sliding plate 7; the right shafts 13 of which output ends are respectively fixed with the right clamping blocks 14 are fixed inside the right bearing seats 12 above the flip plate 5 through the bearing.

(7) In a working process, a sensor is used to position a wheel on a roller way; the clamping air cylinder 11 drives the sliding plate 7 and the two left clamping blocks 10 to push the wheel to a right side through the guide rail I 6; the wheel can be clamped when coming into contact with the two right clamping blocks 14; the servo motor 4 drives the wheel to rotate through the left shafts 9; the sensor recognizes the position of an air valve hole and then identifies a corresponding wheel window position; the turnover air cylinder 3 drives the flip plate 5 and the wheel to turn over by a certain angle through the sliding block 16, the guide rail II 17 and the connecting rod 15. At the moment, a printing head of a pad printer moves downwards to print a fixed pattern onto a front face of the wheel.
