[0020] Embodiment 1

[0021] Reference Figure 1-Figure 5 The shaft head clamping device for a finishing mill shaft connection shown in the figure comprises a clamping mechanism 3 and a shaft connection body 4, the shaft connection body 4 is located at one side of the clamping mechanism 3, the clamping mechanism 3 comprises a mounting plate 31 and a mounting sleeve 32, the mounting sleeve 32 is mounted on one side of the mounting plate 31, a positioning groove 33 is provided on the surface of the mounting sleeve 32, a positioning socket 35 is provided on the inner wall of the positioning groove 33, and a clamping structure 34 for clamping is installed on the outer wall of the mounting sleeve 32;

[0022] A shaft head 41 is installed at one end of the shaft body 4, and a protruding block 42 is installed on the outer wall of the shaft head 41. The protruding block 42 is adapted to the positioning groove 33. A groove 43 is opened inside the protruding block 42. A connecting spring 44 is connected to the inner wall of the groove 43. The other end of the connecting spring 44 is connected to a connecting seat 45. A positioning rod 46 is installed on the other side of the connecting seat 45. One end of the positioning rod 46 is movably inserted into the surface of the protruding block 42, and the other end of the positioning rod 46 is adapted to the positioning socket 35. A limiting sleeve 47 is installed on the inner wall of the groove 43. The positioning sleeve 47 is used to limit the position of the positioning rod 46. When the positioning rod 46 is pushed, the positioning rod 46 and the connecting seat 45 can squeeze the connecting spring 44, and one end of the positioning rod 46 can be moved into the protruding block 42, and then the connecting shaft head 41 is inserted into the mounting sleeve 32. The protruding block 42 can slide in the positioning groove 33, and one end of the positioning rod 46 can be inserted into the positioning hole 35, so as to locate the position of the connecting shaft head 41, so that the positioning of the connecting shaft body 4 can be more accurate, which can effectively reduce the adjustment time and thus effectively improve the production efficiency.

[0023] The clamping structure 34 also includes a shaft frame 341 fixedly mounted on the outer wall of the mounting sleeve 32 and a rotating rod 342 mounted on the upper surface of the shaft frame 341. A stop block 346 is installed inside the shaft frame 341. One end of the rotating rod 342 is connected to a connecting shaft 343. A connecting frame 344 is installed on the outer side of the connecting shaft 343. A clamping block 345 for clamping is installed at one end of the connecting frame 344.
