The connecting mechanism 6 includes a connecting block 601, a connecting groove 602, a spring 603, a movable plate 604 and a clamping groove 605. The connecting block 601 is fixedly connected to the surface of the clamping block connecting ring 3, the connecting groove 602 is arranged on the inner side of the mounting block 5, the spring 603 is fixedly connected to the rear end of the inner cavity of the connecting groove 602, the movable plate 604 is movably connected to the inner cavity of the connecting groove 602, the rear end of the movable plate 604 is fixedly connected to the front end of the spring 603, the clamping groove 605 is arranged on the right side of the connecting groove 602, the surface of the connecting block 601 is movably connected to the inner cavity of the connecting groove 602, the rear end of the inner cavity of the movable groove 4 is fixedly connected with an electric telescopic rod 8, the front end of the electric telescopic rod 8 is fixedly connected to the rear end of the mounting block 5, and the outer side of the rear end of the mounting shaft 2 is fixedly connected with a transmission gear ring 9.

[0023] The above scheme is adopted: through the setting of the electric telescopic rod 8, the mounting block 5 can be driven to move forward and backward, thereby driving the clamp block connecting ring 3 to move, so that the opening of the mounting shaft 2 squeezes the clamping block 7, and the inner cavity of the clamping block 7 contracts to clamp the workpiece. Through the setting of the transmission gear ring 9, the driving motor can be used to drive the mounting shaft 2 and the clamp block connecting ring 3 to rotate, thereby rotating the workpiece.

[0024] refer to Figures 1 to 5 An inspection cover 10 is fixedly installed on the top of the shell 1 by bolts, and a sealing gasket is provided at the connection between the inspection cover 10 and the shell 1. The bottom end of the shell 1 is fixedly connected to a base 11, and four corners of the base 11 are provided with mounting screw holes 12. Limiting grooves 13 are provided on the left and right sides of the movable groove 4, and the two sides of the mounting block 5 are movably connected to the inner cavity of the limiting groove 13.

[0025] The above scheme is adopted: through the setting of the inspection cover 10, the internal components of the shell 1 can be easily inspected and replaced. Through the setting of the base 11, the shell 1 can be supported and the bottom end of the shell 1 can be prevented from contacting and wearing the machine tool. Through the setting of the mounting screw holes 12, the device can be fixed to the specified position of the machine tool using bolts. Through the setting of the limit groove 13, the movement of the mounting block 5 can be limited to prevent it from offsetting and shaking during movement.

[0026] Working principle:

[0027] When in use, the device is installed to the specified installation position of the machine tool by using bolts to penetrate the installation screw holes 12, and the surface of the transmission gear ring 9 is meshed and connected with the output end of the drive motor. The clamping block 7 of the specified specification is selected according to the actual use requirements, and the rear end of the clamping block connecting ring 3 is aligned with the opening of the installation shaft 2 and inserted into the inner cavity of the installation shaft 2. The clamping block 7 is pushed to drive the clamping block connecting ring 3 to move toward the inner side of the installation shaft 2, and the movement of the clamping block connecting ring 3 drives the connecting block 601 to enter the connecting groove 602 The inner cavity of the connecting block 601 pushes the movable plate 604 to move, and the movement of the movable plate 604 drives the spring 603 to contract. When the movable plate 604 moves to the rear end of the inner cavity of the connecting groove 602, the clamping block connecting ring 3 is driven to rotate by rotating the clamping block 7, and the connecting block 601 is driven to move by the rotation of the clamping block connecting ring 3, so that the connecting block 601 moves to the opening of the clamping groove 605. At this time, let go of the hand to make the connecting block 601 lose the thrust, and the spring 603 is rebounded. The movable plate 604 is pushed to move, and the movement of the movable plate 604 drives the connecting block 601 to move to the inner cavity of the clamping groove 605, so that the connecting block 601 is completely clamped into the inner cavity of the connecting groove 602, and the installation of the clamping block 7 is completed. Then the workpiece is placed in the inner cavity of the clamping block 7, and then the electric telescopic rod 8 is controlled to shrink and drive the installation block 5 to move. The movement of the installation block 5 drives the clamping block connecting ring 3 to move toward the rear end of the inner cavity of the installation shaft 2, and the movement of the clamping block connecting ring 3 drives the clamping block 7 to move. The clamping block 7 moves toward the rear end of the inner cavity of the mounting shaft 2 through the clamping block 7, and contacts the inner cavity of the mounting shaft 2 through the inclined surface on the outer side of the clamping block 7, so that the inner side of the mounting shaft 2 squeezes the outer side of the clamping block 7, and there is a gap between the clamping blocks 7, so that the clamping block 7 moves inwardly through the toughness of the clamping block 7, so as to clamp and fix the workpiece, and then control the drive motor to drive the transmission gear ring 9 to rotate, so that the mounting shaft 2 rotates to drive the clamping block 7 to rotate, and the workpiece is rotated by the rotation of the clamping block 7.

[0028] To sum up: this easy-to-adjust tooling fixture for CNC machine tools, through the coordinated work between the components, solves the problem that the replacement process of the clamping block 7 of the existing equipment is cumbersome, time-consuming and labor-intensive during actual use, and when the workpiece specifications are changed, it will greatly delay the working time and reduce work efficiency.
