[0026] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] Referring to Figure 1 And Figure 2 : a end tooth disc finish turning clamp, the clamp includes: rack 1, clamping block 2, archimedes gear 3 and rotary drive mechanism 4, the rack 1 is provided with several clamping blocks 2 around its axis, each clamping block 2 can reciprocate towards the axis direction of rack 1, the archimedes gear 3 is coaxially rotatably arranged at the bottom of rack 1, and its surface is coaxially provided with archimedes spiral 301, the lower surface of each clamping block 2 is provided with a limiting arc block 201 matched with archimedes spiral 301, the rotary drive mechanism 4 is arranged on the rack 1 to drive the rotation of archimedes gear 3.

[0028] The application drives archimedes gear 3 to rotate by starting rotary drive mechanism 4, so that archimedes spiral 301 and limiting arc block 201 cooperate to gradually drive clamping block 2 to reciprocate towards the axis direction of rack 1, thereby realizing the clamping of end tooth disc, since the self-locking ability of archimedes spiral 301 is very strong, clamping block 2 can only be driven to move by rotating archimedes gear 3, and the force applied to clamping block 2 will not drive archimedes gear 3 to rotate, thereby improving the clamping ability of the clamp.

[0029] Referring to Figure 2 And Figure 4 : the rotary drive mechanism 4 includes: drive motor 401 and drive gear 402, the archimedes gear 3 is coaxially provided with several transmission teeth 302 around the side, the drive motor 401 is arranged on the rack 1, and the output end is coaxially provided with drive gear 402 engaged with transmission teeth 302.

[0030] The application drives archimedes gear 3 to rotate by rotating drive gear 402 through transmission teeth 302 by starting drive motor 401.

[0031] Referring to Figure 4The side wall of the driving gear 402 is arc-shaped and matched with the frame 1.

[0032] The driving gear 402 is rotated by the processing, and the scratching and jamming are avoided.

[0033] Referring to Figure 3 The frame 1 is provided with a limiting slide rail 101 corresponding to each clamping block 2, and the clamping block 2 is provided with a limiting slide block 202 matched with the limiting slide rail 101.

Since the self-locking ability of the Archimedes spiral 301 is very strong, the clamping block 2 can only be moved by rotating the Archimedes gear 3, and the force applied to the clamping block 2 will not drive the Archimedes gear 3 to rotate, thereby improving the clamping ability of the clamp.
