[0019] The utility model discloses a kind of CNC automatic grabbing tool shank. Figs. 1-3 The utility model further illustrates.

[0020] To solve the problems in the background art, the present application proposes the following technical solutions: a CNC automatic grabbing tool shank.

[0021] In the specific technical solution, the installation end 1, the fixed sheet 2, and the connection end 3 are fixedly connected in sequence. A connection groove 4 for connecting the tool head 13 is formed on one end of the outer wall of the connection end 3. An automatic gripping assembly 5 is arranged inside the connection end 3 for automatically clamping the tool head 13. The tool head 13 can be automatically clamped and fixed by the automatic gripping assembly 5.

[0022] In the specific implementation, the automatic gripping assembly 5 includes a pressure boosting mechanism 6 and a plurality of clamping mechanisms 7. A pressure boosting cavity 8 is formed on the other end of the outer wall of the connection end 3. A plurality of U-shaped grooves 9 are formed between the inner wall of the pressure boosting cavity 8 and the inner wall of the connection groove 4. A through hole is formed between the U-shaped groove 9 and the inner wall of the connection groove 4, thereby enabling communication between the pressure boosting cavity 8 and the connection groove 4. The clamping mechanism 7 is arranged inside the U-shaped groove 9 on the inner wall of the connection groove 4. The clamping mechanism 7 includes a clamping rod 701, a sealing sheet 702, and a mounting spring 703. The sealing sheet 702 is mounted on the inner wall of the U-shaped groove 9 by the mounting spring 703. The sealing sheet 702 is limited by the mounting spring 703. The clamping rod 701 is mounted on one side of the sealing sheet 702 and one end is clamped in the through hole. The pressure boosting mechanism 6 is arranged in the pressure boosting cavity 8. The pressure boosting mechanism 6 is used to control the movement of the clamping mechanism 7. Under the control of the pressure boosting mechanism 6, the clamping rod 701 can be pushed into the connection groove 4, thereby clamping and fixing the tool head 13 from various positions, and further achieving automatic gripping.
