DETAILED DESCRIPTION

[0017] The following is a specific embodiment of the novel six-jaw chuck and a further description of the technical solution of the novel six-jaw chuck in combination with the drawings, but the novel six-jaw chuck is not limited to these embodiments. EMBODIMENT

[0018] As shown in the drawings, a novel six-jaw chuck for offsetting centrifugal force comprises a mounting block 1 and a jaw structure 2. Figs. 1 to 4 The mounting block 1 is provided with a connecting structure connected with an external driving device, the connecting structure comprises a first connecting block 7 provided on the mounting block 1, a second connecting block 8 connected with the first connecting block 7, a positioning disc 9 on the second connecting block 8, and a plurality of supporting blocks 10 provided on the positioning disc 9.

[0019] The clamping jaw structure 2 comprises a clamping jaw mounting base 21 and a clamping tooth 22 arranged on the clamping jaw mounting base 21, one side of the mounting step 4 is provided with a clamping groove 5, and the clamping tooth 22 is provided with a clamping block 6 matched with the clamping groove 5, and during installation, the clamping block 6 on the clamping tooth 22 is horizontally clamped into the clamping groove 5, so that the upper and lower positions of the clamping tooth 22 are limited.

[0020] The clamping jaw mounting base 21 is provided with a mounting step 4, and the clamping tooth 22 is arranged on the mounting step 4; in this embodiment, the clamping tooth 22 is fixedly arranged on the mounting step 4 through bolts.
