[0026] Please see Figure 1 As shown, this utility model provides a technical solution: a high-speed cutting tool head device for cast steel processing, including a gripping device 1 and a tool head body 5. The lower end of the gripping device 1 is provided with a receiving cavity 3 for placing the tool head body 5. A locking device 4 for clamping and fixing the tool head body 5 is sleeved on the outside of the receiving cavity 3. A servo motor 6 for rotating the locking device 4 is provided on the side of the receiving cavity 3.

[0027] The gripper 105 of the gripping device 1 is located inside the receiving cavity 3. The first hydraulic cylinder of the gripping device 1 is fixed above the receiving cavity 3. The first hydraulic rod 101 of the first hydraulic cylinder is linked with the gripper 105. The gripper 105 performs the gripping work of the cutter head body 5. The receiving cavity 3 is fitted with a locking device 4. The locking device 4 fixes the cutter head body 5 inside the receiving cavity 3. After the gripper 105 grips the cutter head body 5, the locking device 4 performs further work to ensure that the cutter head body 5 will not fall or slide during high-speed rotating cutting.

[0028] As one implementation method in this embodiment, please refer to Figures 6-7 As shown, the gripping device 1 includes a first hydraulic rod 101, with a flange 2 sleeved on the outside of the first hydraulic rod 101. The lower end of the flange 2 is fixed to the upper end of the receiving cavity 3. A positioning cavity 102 is fixedly connected to the lower end of the first hydraulic rod 101. A second hydraulic cylinder 103 is provided inside the positioning cavity 102. The upper end of the second hydraulic cylinder 103 is fixed at the center of the inner side of the upper end of the positioning cavity 102. A second hydraulic rod 109 extends from the lower end of the second hydraulic cylinder 103, penetrating the lower end of the positioning cavity 102. A movable block 104 is fixedly connected to the end of the 109 penetrating through. Multiple first connecting rods 110 are movably connected to the outside of the movable block 104. Multiple grippers 105 are movably connected to the ends of the multiple first connecting rods 110 away from the movable block 104. Multiple ear blocks 108 are sleeved on the outside of the multiple grippers 105. A support block 106 is fixedly connected inside the multiple ear blocks 108. The multiple ear blocks 108 and the support block 106 are movably connected by pins 107. The top end of the support block 106 is fixedly connected to the bottom end of the outer wall of the positioning cavity 102.

[0029] The first hydraulic rod 101 is fixed to the upper end of the receiving cavity 3 via the flange 2, allowing the first hydraulic rod 101 to move vertically up and down inside the receiving cavity 3. The lower end of the first hydraulic rod 101 is fixedly connected to the positioning cavity 102, which moves up and down with the first hydraulic rod 101. A second hydraulic cylinder 103 is installed inside the positioning cavity 102. The second hydraulic rod 109 of the second hydraulic cylinder 103 passes through the positioning cavity 102 and is fixedly connected to the moving block 104. A gripper 105 is movably connected to the outside of the moving block 104. The gripper 105 is L-shaped, and an ear block 108 is sleeved on the outer side of the middle section of the gripper 105. The contact surfaces of 105 and ear block 108 are movably connected by pin 107. Ear block 108 is fixedly connected to support block 106. The outer side of support block 106 is fixedly connected to the outer edge of the bottom wall of positioning cavity 102. The second hydraulic cylinder 103 moves up and down through the second hydraulic rod 109, causing the moving block 104 fixed to the second hydraulic rod 109 to move up and down. The gripper 105 movably connected to the moving block 104 can then retract. That is, when the second hydraulic rod 109 moves upward, the gripper 105 retracts inward; conversely, when the second hydraulic rod 109 moves downward, the gripper 105 expands outward.

[0030] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the cavity 3 has multiple grooves 301 inside, and multiple clamping blocks 407 are fitted inside the multiple grooves 301.

[0031] As one implementation method in this embodiment, please refer to Figure 2 and Figure 5 As shown, the locking device 4 includes a circular cylinder 401, which is sleeved on the outer wall of the receiving cavity 3. An internal gear 402 is provided on the inner wall of the upper end of the circular cylinder 401. Multiple movable wedge blocks 403 are fixed at the lower end of the internal gear 402 in the middle of the circular cylinder 401. Multiple passive wedge blocks 404 are provided on the opposite side of the multiple movable wedge blocks 403. The multiple movable wedge blocks 403 correspond one-to-one with the multiple passive wedge blocks 404, and the movable wedge blocks 403 slide outside the passive wedge blocks 404. Multiple linkage rods 405 are fixed on the side of the multiple passive wedge blocks 404 away from the movable wedge blocks 403. Multiple springs 406 are sleeved on the outside of the multiple linkage rods 405. The multiple linkage rods 405 pass through the groove 301 and are fixedly connected to multiple clamping blocks 407 one-to-one. A second active wedge tooth 408 is fixed on the side of the multiple clamping blocks 407 away from the linkage rods 405.

[0032] The locking device 4 includes an annular cylinder 401, an internal gear 402, multiple movable wedges 403, multiple passive wedges 404, multiple linkage rods 405, multiple springs 406, and multiple clamping blocks 407. Taking one clamping block 407 as an example, the clamping block 407 is located in the groove 301 inside the receiving cavity 3. The linkage rod 405 extends through the side wall of the receiving cavity 3 and into the groove 301. One side of the linkage rod 405 is fixedly connected to the clamping block 407, and the other side of the linkage rod 405 is fixedly connected to the passive wedge 404. The spring 406 is sleeved outside the linkage rod 405 and located between the outer wall of the receiving cavity 3 and the passive wedge 404. The passive wedge 404 is provided with a movable wedge 403 on the opposite side. The movable wedge 403 is fixed to the inner wall of the annular cylinder 401. The internal gear 402 is fixedly provided at the upper end of the inner wall of the annular cylinder 401.

[0033] Rotate the annular cylinder 401 in one direction, causing the movable wedge block 403 to slide and press against the passive wedge block 404. The passive wedge block 404 drives the linkage rod 405 to press the clamping block 407 inward. Multiple clamping blocks 407 move inward simultaneously to form a cylindrical shape. Rotate the annular cylinder 401 in the opposite direction, and the movable wedge block 403 moves away from the passive wedge block 404. The clamping block 407 is moved into the groove 301 by the spring 406, that is, the multiple clamping blocks 407 expand in diameter and retract.

[0034] As one implementation method in this embodiment, please refer to Figure 5 As shown, the upper end of the cutter head body 5 is provided with a pull stud 501, and the lower end of the pull stud 501 is fixedly provided with a second driven wedge tooth 502.

[0035] When the pull stud 501 at the upper end of the cutter head body 5 is grasped by the gripper 105 and lifted upward by the first hydraulic rod 101, the clamping block 407 of the locking device 4 presses inward, causing the second driven wedge tooth 502 fixed at the lower end of the pull stud 501 to engage with the second active wedge tooth 408 on the outer side of the clamping block 407. This completes the secondary locking action of the cutter head body 5, so that the cutter head body 5 is fitted inside the clamping block 407. This prevents the cutter head body 5 from falling off during high-speed rotation cutting due to the loosening of the gripper 105 during high-speed rotation, which could damage the cast steel product during the casting process. The engagement of the second active wedge tooth 408 with the second driven wedge tooth 502 also prevents the cutter head body 5 from slipping during high-speed rotation, enhancing the stability of the rotation of the cutter head body 5.

[0036] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a motor fixing block 601 is fixedly connected to the upper end of the servo motor 6. One end of the motor fixing block 601 is fixedly connected to the outer wall of the receiving cavity 3. A motor gear 602 is fixedly connected to the lower output shaft of the servo motor 6. The motor gear 602 meshes with the internal gear 402.

[0037] The servo motor 6 is fixed to the outer wall of the receiving cavity 3 by the motor fixing block 601. The lower output shaft of the servo motor 6 is fixedly connected to the motor gear 602. The motor gear 602 meshes with the internal gear 402. When the servo motor 6 rotates forward, the moving wedge block 403 slides and presses against the passive wedge block 404. When the servo motor 6 rotates in reverse, the moving wedge block 403 moves away from the passive wedge block 404.

[0038] Working principle: The operator inserts the cutter head body 5 from bottom to top into the receiving cavity 3, and activates the second hydraulic cylinder 103, causing the second hydraulic cylinder 103 to drive the second hydraulic rod 109 to move upward. The second hydraulic rod 109 drives the moving block 104 to move upward. The moving block 104 is movably connected to the gripper 105 on the outside. The gripper 105 is L-shaped, and an ear block 108 is sleeved on the outer side of the middle section of the gripper 105. The contact surfaces of the gripper 105 and the ear block 108 are movably connected by a pin 107. The ear block 108 is fixedly connected to the support block 106. The outer side of the support block 106 is connected to the positioning cavity. The outer edge of the bottom wall of 102 is fixedly connected, that is, the gripper 105 on the moving block 104 retracts inward to grasp the pull stud 501 set on the upper end of the cutter head body 5. The first hydraulic rod 101 is activated back and forth to move the cutter head body 5 upward. Then the servo motor 6 is activated to generate forward rotation, so that the moving wedge block 403 slides and presses against the passive wedge block 404. The clamping block 407 is pressed inward through the linkage rod 405. The second driven wedge tooth 502 fixed at the lower end of the pull stud 501 is engaged with the second active wedge tooth 408 on the outer side of the clamping block 407, completing the secondary locking action of the cutter head body 5.
