[0029] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0030] Please refer to Figures 1-5 The present application provides a ball head tool 1 for assembling a seat back 2, which comprises a positioning assembly 11, a turnover assembly 12 and a supporting assembly 13. The supporting assembly 13 comprises a support plate 1301, a support frame 1302 and a rotating shaft 1303. The support frame 1302 is fixed on the support plate 1301 for the rotating shaft 1303 to be connected.

[0031] The positioning assembly 11 comprises a positioning plate 111, a supporting plate 112 and a ball head rod 113.

The side surface of the positioning plate 111 is provided with a protruding positioning rod 114 for the seat back 2 to be inserted. The supporting plate 112 is located on one side of the positioning rod 114 and is fixedly connected with the positioning plate 111 to support the seat back 2. The ball head rod 113 is hinged to one side of the supporting plate 112 to fix the seat back 2.

[0032] The turnover assembly 12 comprises a turnover driving piece 1201, a worm gear 1202 and a worm 1203. The worm gear 1202 is fixed on the rotating shaft 1303 between the positioning plate 111 and the support frame 1302. The turnover driving piece 1201 is fixed on the support plate 1301 and is connected with the worm gear 1202 through the worm 1203 to drive the worm gear 1202 to rotate and drive the positioning assembly 11 to rotate.

[0033] During the assembly of the seat back 2, the operator carries the seat back 2 to the positioning assembly 11 and inserts the positioning rod 114 on the side surface of the positioning plate 111 into the seat back 2. At the same time, the supporting plate 112 supports the seat back 2. Then, the operator rotates the ball head rod 113 to make the ball head rod 113 contact and fix the seat back 2, so that the seat back 2 does not move during the assembly process.

[0034] When the seat back 2 needs to be turned over, the turning drive 1201 (such as a motor) is started to drive the worm 1203 to rotate, and the worm 1203 is engaged with the worm gear 1202 to drive the worm gear 1202 to rotate. Since the worm gear 1202 is fixed on the rotating shaft 1303 between the positioning plate 111 and the support frame 1302, the rotation of the worm gear 1202 drives the rotating shaft 1303 to rotate, and then drives the positioning assembly 11 fixedly connected with the rotating shaft 1303 to rotate, thereby realizing the turning over of the seat back 2. The operator can control the running time and angle of the turning drive 1201 according to the requirements of the assembly process, and turn the seat back 2 to the appropriate angle for subsequent assembly operation. Compared with the manual turning over of the seat back 2, the ball head tool 1 can save the physical strength of the operator, reduce the labor intensity, and improve the work efficiency.
