[0042] Working principle: First, rotate the adjusting bolt 7 to remove the claw block 6 from the left side of the chuck body 1, and then extend the right side of the friction column 303 to the inside of the flange 2, so that the surface of the alignment column 301 contacts the inner wall of the chuck body 1, and the alignment column 301 is in an inclined state, so that the chuck body 1 can be limited and supported, and the body bolt 5 can be rotated to remove the chuck body 1 from the left side of the flange 2, so that the chuck body 1 slides on the surface of the alignment column 301 due to its own gravity, so that the chuck body 1 drives the limiting frame 302 to move, and under the friction of the limiting block 9, the speed at which the chuck body 1 slides down is reduced, and then it contacts the right side of the protective pad 12, thereby driving the support plate 14 to compress the buffer column 15, thereby further reducing the moving speed of the chuck body 1 and reducing the damage to the chuck body 1 during disassembly. The limit frame 302 is then moved so that the limit frame 302 drives the connecting column 11 to move, and the connecting column 11 drives the cylinder to move inside the connecting groove 8, so that the surface of the fixed column 10 is away from the inside of the connecting groove 8, and then the chuck body 1 is moved through the connecting column 11, so that the chuck body 1 is taken out, avoiding the collision between the chuck body 1 and other machines, and solving the problem that most existing chucks are not convenient for quick disassembly of the chuck body 1 with quick-release tooling. Usually, the chuck body 1 is supported and fixed by a lifting structure, and then the bolts are loosened to disassemble the chuck body 1, and then a small crane is used to drive the chuck body 1 to move to a suitable position, and the chuck body 1 is removed for maintenance. When the chuck body 1 moves, it is easy to collide with the surrounding machinery, which may affect the normal use of the chuck body 1 and the machinery.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
