The opening and closing mechanism includes four sets of mounting rods 501, one end of the mounting rod 501 is hinged to the lifting platform 402, and one end of each two sets of mounting rods 501 is hinged to one of the centering blocks 505, and each two sets of mounting rods 501 are parallel, the mounting rod 501 is provided with a guide groove 502 extending along its axis, and the mounting rod 501 is further provided with two sets of threaded cylinders 503, the threaded cylinders 503 are provided with guide columns 504 at both ends, the guide columns 504 are slidingly clamped in the guide groove 502, the lifting platform 402 is provided with a rotatable bidirectional screw rod 404, the two sets of threaded cylinders 503 are respectively sleeved on both ends of the bidirectional screw rod 404 and are screwed with the bidirectional screw rod 404, the end of the bidirectional screw rod 404 is exposed outside the shell 101 and is connected with a second adjusting wheel 405, and the bottom of the centering block 505 is provided with two rotatable centering wheels 506.

[0055] The second adjusting wheel 405 can drive the bidirectional screw rod 404 to rotate on the lifting platform 402, and since the lifting platform 402 is provided with a positioning track 403, the extension direction of the positioning track 403 is parallel to the axis of the bidirectional screw rod 404, the guide column 504 is slidingly clamped in the positioning track 403, and the movement of the threaded cylinder 503 is positioned through the cooperation of the positioning track 403 and the guide column 504, so that the bidirectional screw rod 404 can drive the two sets of threaded cylinders 503 to move in opposite directions during rotation, the threaded cylinder 503 drives the guide column 504 to move during movement, the mounting rod 501 is driven to rotate along the hinge point with the lifting platform 402 through the cooperation of the guide column 504 and the guide groove 502, and each two sets of mounting rods 501 cooperate with the lifting platform 402 and the centering block 505 to form a parallelogram structure, that is, the distance between the two sets of centering blocks 505 can be adjusted by rotating the bidirectional screw rod 404, so that the centering wheels 506 at the bottom of the centering blocks 505 are in contact with the boss, and the position of the rotating shaft 102 or the workpiece is adjusted at the same time, so that the four centering wheels 506 are in contact with the inner or outer circular surface of the boss at the same time, that is, the centering of the rotating shaft 102 and the workpiece is completed, so that the axis of the rotating shaft 102 coincides with the axis of the boss to be machined, avoiding the shift of the boss machining, so as to improve the machining precision.

[0058] When the device is used, the mounting disc 104 is moved above the boss of the workpiece to be machined, the lifting platform 402 is controlled to descend by the hydraulic telescopic rod 401, so that the centering block 505 moves to the inside or outside of the boss, and then the bidirectional screw rod 404 is driven to rotate by rotating the second adjusting wheel 405, so that the two groups of threaded barrels 503 move in opposite directions. The threaded barrel 503 drives the mounting rod 501 to rotate along the hinge point with the lifting platform 402 by cooperating with the guide column 504 and the guide groove 502 during the movement, and the two groups of mounting rods 501 cooperate with the centering block 505 to form a parallelogram structure during the movement, thereby driving the centering block 505 to move, so as to control the opening and closing of the two groups of centering blocks 505, so that the four groups of centering wheels 506 on the two groups of centering blocks 505 contact the inner or outer circular surface of the boss. The opening and closing of the centering block 505 is controlled at the same time, and the machine tool spindle or the workpiece is translated, until the distance between the two groups of centering blocks 505 in the inner circle of the boss is the longest and contacts the inner circle of the boss, or the distance between the two groups of centering blocks 505 is the shortest when contacting the outer circle of the boss, so that the rotating shaft 102 of the device coincides with the axis of the boss, and the centering work is completed.

[0059] Then the two groups of threaded rods 302 are driven to rotate by rotating the first adjusting wheel 303, and the sliding frame 201 slides along the axis in the sliding groove 105 by cooperating with the threaded groove 202 during the rotation of the threaded rod 302, thereby driving the cutter 207 to follow the movement, so as to adjust the circular distance between the cutter 207 and the mounting disc 104, so that the cutter 207 contacts the machined surface of the boss, and then the rotating shaft 102 is controlled to rotate to machine the boss, thereby effectively avoiding the deviation during subsequent machining of the boss, and improving the machining accuracy of the boss.
