[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5This utility model relates to a milling device for machining the cutting edge contour of an automotive mold. It includes a milling machine 1, which has a built-in function for lateral movement of the work plate 2 and can also raise, lower, and move the drive box 3 forward and backward to ensure that the cutting tool 7 can machine the cutting edge contour of the automotive mold. A control system is fixedly connected to one side of the milling machine 1 to drive the cutting tool 7 to rotate. The work plate 2 is mounted on the top of the milling machine 1, and the drive box 3 is fixedly connected to the top of the milling machine 1. A replacement assembly is located at the bottom of the drive box 3, including a drive head 4 fixedly connected to the bottom of the drive box 3. The drive head 4, through the cooperation of a hexagonal slot 13 and a hexagonal plug 14, enables the quick installation and removal of the cutting tool 7. A limiting sleeve 8, through the cooperation of a first spring 9 and a wedge block 10, ensures the precise positioning of the cutting tool 7. The drive system inside the drive box 3 can drive the drive head 4 to rotate. The mounted cutting tool 7 rotates, and the mounting sleeve 5 is movably connected to the bottom of the drive head 4, and the disassembly plate 6 is set at the bottom of the mounting sleeve 5. The disassembly plate 6 can slide at the bottom of the mounting sleeve 5 to facilitate the separation of the cutting tool 7 from the inner cavity of the drive head 4, so as to facilitate the replacement of the cutting tool 7. The cutting tool 7 can be quickly replaced by the replacement component. The bottom of the disassembly plate 6 is provided with a limiting component, which includes the cutting tool 7 set at the bottom of the drive head 4, a limiting sleeve 8 fixedly connected to one side of the surface of the cutting tool 7, the limiting sleeve 8 allows the cutting tool 7 to be installed into the drive head 4, a first spring 9 fixedly connected to both sides of the inner cavity of the limiting sleeve 8, the first spring 9 can automatically reset the wedge block 10 to ensure that the cutting tool 7 can be installed into the drive head 4, and a wedge block 10 fixedly connected to one end of the first spring 9, which limits the cutting tool 7 through the limiting component.

[0028] Example 2

[0029] Please see Figures 1-5Based on embodiment 1, the replacement component also includes a right-angle plate 11. When the right-angle plate 11 moves, it will press against the inclined block 10 to release the limit of the cutter 7. The right-angle plate 11 is fixedly connected to the top two sides of the disassembly plate 6. A second spring 12 is fixedly connected to the top of the right-angle plate 11. The second spring 12 can make the right-angle plate 11 automatically return to its original position, ensuring that the disassembly plate 6 is in the corresponding position when the cutter 7 is installed, and will not affect the installation work. One end of the second spring 12 is fixedly connected to the top of the inner cavity of the mounting sleeve 5. The inner cavity of the drive head 4 has a hexagonal groove 13. One end of the cutter 7 is fixedly connected to a hexagonal plug 14. The hexagonal groove 13 and the hexagonal plug 14 engage to ensure that the driving force in the drive box 3 drives the cutter 7 to rotate. The surface of the hexagonal plug 14 is slidably connected to the inner cavity of the hexagonal groove 13. The bottom of the limiting sleeve 8 is fixed. A limiting ring 15 is fixedly connected to limit the disassembly plate 6. In the default state, there is a certain space between the limiting ring 15 and the disassembly plate 6 so that when the disassembly plate 6 is moved, the right-angle plate 11 will squeeze the inclined block 10, so that the tool 7 will separate from the inner cavity of the drive head 4. The inner cavity of the limiting sleeve 8 is provided with release ports on both sides. One side of the inner cavity of the limiting port is fixedly connected to one end of the first spring 9. The inner cavity of the mounting sleeve 5 is provided with a positioning hole 16. The positioning hole 16 at the top of the mounting sleeve 5 is hexagonal and the bottom is round to accommodate the shape of the hexagonal plug 14 and the shape of the limiting sleeve 8. The surface of the tool 7 is slidably connected to the inner cavity of the positioning hole 16. The bottom sides of the mounting sleeve 5 are provided with a sliding groove 17. The surface of the right-angle plate 11 is slidably connected to the inner cavity of the sliding groove 17 so that the right-angle plate 11 will squeeze the inclined block 10 when it moves.

[0030] The working principle of this utility model is as follows: When it is necessary to replace the tool 7, the operator moves the disassembly plate 6, which slides at the bottom of the mounting sleeve 5, causing the right-angle plate 11 to move. During the movement, the right-angle plate 11 applies pressure to the inclined block 10, causing the inclined block 10 to compress the first spring 9, thereby releasing the limit between the tool 7 and the drive head 4. As the disassembly plate 6 continues to move, the tool 7 separates from the inner cavity of the drive head 4. At this time, the tool 7 can be taken out from the bottom of the drive head 4. The new tool 7 is inserted through the positioning hole 16 at the bottom of the mounting sleeve 5. The hexagonal plug 14 slides and connects with the hexagonal groove 13 in the inner cavity of the drive head 4 to ensure the precise alignment of the tool 7 and the drive head 4. When the tool 7 is inserted into place, the disassembly plate 6 is reset, the right-angle plate 11 is automatically reset under the action of the second spring 12, and the inclined block 10 returns to its original position under the action of the first spring 9, firmly fixing the tool 7 inside the drive head 4, thus completing the quick replacement of the tool 7.

[0031] The limiting assembly, through the cooperation of the limiting sleeve 8, the first spring 9, and the wedge block 10, ensures that the tool 7 can be accurately positioned and firmly fixed during installation. The limiting ring 15 at the bottom of the limiting sleeve 8 is used to limit the movement range of the disassembly plate 6, ensuring that the disassembly plate 6 will not exceed the preset position when moving. After the tool 7 is installed in place, the wedge block 10 automatically resets under the action of the first spring 9, firmly fixing the tool 7 inside the drive head 4, avoiding the problem of decreased machining accuracy caused by the tool 7 loosening or shifting.

[0032] After the tool 7 is replaced, the drive system inside the drive box 3 drives the drive head 4 to rotate. The drive head 4 transmits the driving force to the tool 7 through the cooperation of the hexagonal slot 13 and the hexagonal plug 14, causing the tool 7 to rotate at high speed. The work plate 2 and the drive box 3 move laterally, up and down and back and forth under the control of the milling machine 1, ensuring that the tool 7 can perform efficient and precise milling of the contour of the cutting edge of the automotive mold.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
