[0016] It should also be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0017] Example 1 See attached document Figure 1-3This application provides a milling cutter calibration device for a milling machine, including a magnetic base 1. A switch 2 is provided on the magnetic base 1, which is fixed to the worktable of a milling machine 25. The switch 2 controls the magnitude and on / off state of the magnetic force. A fine-tuning mechanism 3 is provided on the magnetic base 1. A first support rod 4 is provided at the output end of the fine-tuning mechanism 3. The first support rod 4 has a connecting block 5, and a second support rod 6 is provided on the connecting block 5. The tail end of the second support rod 6 is connected to a mounting base 7, on which a dial indicator 8 is provided. The connecting block 5 has a through hole that mates with the first support rod 4 and the second support rod 6, and a threaded hole penetrating the through hole. A first fixing member 9 is provided for fixing the first support rod 4, and a second fixing member 10 is provided for fixing the second support rod 6. Both the first fixing member 9 and the second fixing member 10 are threadedly connected to the aforementioned threaded hole. Optionally, the first fixing member 9 and the second fixing member 10 can be ordinary screws, which are easy to obtain and replace. Specifically, the fine-tuning mechanism 3 includes a base frame 11, a guide rail 12, a slider 13, a screw 14, a nut 15, and a moving plate 16. The base frame 11 is connected to the magnetic base 1, the screw 14 is rotatably connected to the base frame 11, the guide rail 12 is connected to the base frame 11, and the slider 15 is slidably engaged with the magnetic base 16. The guide rail 12 and the nut 15 are connected to the screw 14. The nut 15 is connected to a connector 17, which is connected to the slider 13. The slider 13 is connected to the moving plate 16. The first support rod 4 is connected to the moving plate 16. By rotating the screw 14 in both directions, the moving plate 16 moves back and forth. The movement of the moving plate 16, in turn, moves the first support rod 4, thereby realizing the feed and retraction of the dial indicator 8. The first support rod 4 is connected to the moving plate 16. A magnetic shielding plate 18 is provided between the fine-tuning mechanism 3 and the magnetic base 1. Optionally, the fine-tuning mechanism 3 also includes a dust baffle 19. During operation, after assembling the device, place the magnetic base 1 on the worktable of the milling machine 25. Loosen the first fixing member 9 and adjust the connecting block 5 vertically to a suitable position. Then, loosen the second fixing member 10 and adjust the second support rod 6 horizontally to a suitable position. At the same time, the second support rod 6 can be rotated to adjust the angle of the dial indicator 8. After roughly aligning it with the milling cutter 26, the dial indicator 8 is slowly moved towards the milling cutter 26 for calibration through the fine adjustment mechanism 3. Start the milling machine 25 and rotate the milling cutter 26 to observe the data change of the dial indicator 8 to determine the runout of the milling cutter 26. During the process, the dial indicator 8 can be finely adjusted through the fine adjustment mechanism 3 to avoid collision. The structure is simple and the operation is convenient.

[0018] Example 2 See attached document Figure 1-3The difference between this embodiment and Embodiment 1 is that the second bracket is provided with an anti-rotation ridge 20, the connecting block 5 is provided with a groove that cooperates with the anti-rotation ridge 20, the anti-rotation ridge 20 is a square structure, the mounting base 7 is rotatably connected to the second support rod 6, and the mounting base 7 is provided with a third fixing member 24 for fixing the mounting base 7. The anti-rotation ridge 20 limits the second support rod 6, making it convenient to adjust the second support rod 6 along the axial direction of the above-mentioned through hole, which facilitates adjustment and avoids the influence of rotation during adjustment. The rotatable connection between the mounting base 7 and the second support rod 6 facilitates the adjustment of the angle of the dial indicator 8. This design separates the linear adjustment and rotation adjustment of the second support rod 6, making it easier to use and operate.

[0019] Specifically, the fine-tuning mechanism 3 is provided with a base 21, the base 21 is provided with a mounting hole 22, the first support rod 4 is installed on the mounting hole 22, the base 21 is provided with a fourth fixing member for fixing, and the dial indicator 8 can be rotated and adjusted along the Z-axis by the first support rod 4 being installed on the mounting hole 22, which also facilitates the installation and replacement of the first support rod 4 of different lengths.

[0020] Specifically, one end of the screw 14 is connected to the knob 23, and the knob 23 is provided with anti-slip texture to facilitate the rotation of the screw 14.
