[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 6This utility model provides a technical solution: It includes a machine tool worktable 1, a moving module 2 on the upper side of the worktable 1, a processing module 3 on one side of the moving module 2, a mounting base 4 fixedly connected to the lower end of the processing module 3, a mounting shell 5 on the lower side of the mounting base 4, a drive disk 6 rotatably fitted to the inner wall of the mounting shell 5, a drive rod 7 fixedly connected to one side of the drive disk 6, multiple sector plates 8 fixedly connected to the upper side of the mounting shell 5, a locking mechanism 9 on the upper side of the mounting shell 5, an arc-shaped shell 10 on one side of the mounting shell 5, a milling cutter 11 on the lower side of the mounting shell 5, a limit mechanism 12 inside the drive rod 7, and circular grooves 13 at corresponding positions of the drive disk 6 and the arc-shaped shell 10. The upper side of the sector plates 8 is fixedly connected to the lower side of the mounting base 4, and multiple sector plates 8 are evenly arranged on the upper side of the mounting shell 5. The milling cutter 11 slides within the inner wall of the circular groove 13. Both sides of the milling cutter 11 are fixedly connected to arc-shaped blocks 14, and both sides of the inner wall of the circular groove 13 are provided with arc-shaped grooves 15 that cooperate with the arc-shaped blocks 14. The machine tool worktable 1 serves as the basic support, and the moving module 2 can move above it, driving the machining module 3 to adjust its position. The machining module 3 is connected to the structure below through the mounting base 4. The mounting shell 5 is installed on the lower side of the mounting base 4, the drive disk 6 rotates inside the mounting shell 5, and the drive rod 7 is fixed to one side of the drive disk 6. The machine tool worktable 1 provides stable support. The moving module 2 and the machining module 3 realize the flexible movement and positioning of the device in the machining space, providing the basic conditions for subsequent milling. The combination of the drive disk 6 and the drive rod 7 provides power and connection basis for the driving and adjustment of the milling cutter 11. The sector plate 8 enhances the stability of the connection between the mounting shell 5 and the mounting base 4. The cooperation between the arc-shaped blocks 14 and the arc-shaped grooves 15 restricts the movement direction of the milling cutter 11 in the circular groove 13, ensuring the stability and accuracy of the milling cutter 11 installation and preventing it from deviating during the machining process. In this embodiment, the locking mechanism 9 includes multiple cam grooves 91 evenly spaced on the upper side of the drive disc 6, guide grooves 92 on opposite sides of multiple sector plates 8, a movable seat 93 slidably fitted between the inner walls of two corresponding guide grooves 92, a guide rod 94 fixedly connected to the lower side of the movable seat 93, and insert blocks 95 fixedly connected to the near side of each of the multiple movable seats 93. Slots 96 are evenly spaced on the outer side of the milling cutter 11. The guide rods 94 slidably fit on the inner walls of the cam grooves 91, the insert blocks 95 are inserted into the slots 96, and the movable seats 93 slidably fit between two corresponding sector plates 8. Rotating the drive disk 6 causes the cam groove 91 on it to rotate accordingly. The guide rod 94, which slides in cooperation with the inner wall of the cam groove 91, drives the moving seat 93 to slide in the guide groove 92. When the moving seat 93 moves, the insert block 95 inserts into or pulls out of the slot 96 on the outside of the milling cutter 11, thereby locking and releasing the milling cutter 11. Through the rotation of the drive disk 6, the cooperation between the cam groove 91 and the guide rod 94 enables the insert block 95 to automatically lock and release the milling cutter 11, making it convenient and quick to replace the milling cutter 11. At the same time, it ensures that the milling cutter 11 is firmly fixed during processing, improving processing accuracy and stability.In this embodiment, the limiting mechanism 12 includes a mounting groove 121 formed inside the drive rod 7. A rectangular plate 122 is slidably and elastically fitted on one side of the inner wall of the mounting groove 121. A pressing groove 123 is formed on one side of the rectangular plate 122. A locking rod 124 is slidably fitted on the lower side of the inner wall of the mounting groove 121. A pressure rod 125 is slidably fitted on one side of the drive rod 7. Two locking grooves 126 that cooperate with the pressure rod 125 are formed on the lower side of the inner wall of the arc-shaped shell 10. The upper end of the locking rod 124 is slidably fitted with the rectangular plate 122, and the upper end of the locking rod 124 is slidably fitted on the inner wall of the pressing groove 123. The lower end of the locking rod 124 extends to the lower side of the drive rod 7. One end of the pressure rod 125 is fixedly connected to one side of the rectangular plate 122. Pressing the pressure rod 125 causes the rectangular plate 122 to slide within the mounting groove 121. The extrusion groove 123 on the rectangular plate 122 pushes the locking rod 124 to slide on the lower side of the inner wall of the mounting groove 121, causing the lower end of the locking rod 124 to extend out from the lower side of the drive rod 7 or retract. At the same time, the pressure rod 125 can be inserted into or pulled out of the slot 126 on the lower side of the inner wall of the arc-shaped shell 10. By operating the pressure rod 125, the positions of the locking rod 124 and the pressure rod 125 are controlled, thereby limiting and unlocking the relative position of the drive rod 7 and the arc-shaped shell 10. During processing, the position of the drive rod 7 is fixed, ensuring the stable operation of the milling cutter 11. When using the device, first place the workpiece in a suitable position on the machine tool worktable 1. Adjust the overall position of the device through the moving module 2 and the processing module 3 so that the milling cutter 11 is aligned with the processing part. If the milling cutter 11 needs to be replaced, press the pressure rod 125 to retract the locking rod 124 and disengage the pressure rod 125 from the slot 126, thereby releasing the limit on the drive rod 7. Rotate the drive rod 7 to drive the drive disk 6 to rotate. The cam groove 91 on the drive disk 6 drives the guide rod 94 to move the moving seat 93. The insert block 95 is pulled out from the slot 96 of the milling cutter 11, so that the old milling cutter 11 can be removed and the new milling cutter 11 can be installed. After installation, rotate the drive rod 7 in the opposite direction, insert the insert block 95 into the slot 96, and lock the milling cutter 11. After adjustment, release the pressure rod 125, extend the locking rod 124, insert the pressure rod 125 into the slot 126, and re-limit the drive rod 7 to prevent accidental activation.
