DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 to further illustrate the present application in detail.

[0019] Embodiment 1

[0020] Refer to Figures 1 - 3, A milling cutter for precision machining, including a stable base 1. There is an embedding hole 2 in the middle of the top end of the stable base 1. Hidden vertical grooves 3 are provided at both ends of the outer side of the stable base 1. Three fixing screws 4 are rotatably connected through the inner side of the hidden vertical groove 3 and penetrate the stable base 1. Side fixing ears 5 are welded to both ends of the outer side of the stable base 1. Rotating seats 6 are rotatably connected to the inner sides of the side fixing ears 5. An expansion rod 8 is embedded in one end of the rotating seat 6. A shielding cover screw port 7 is welded to the outer surface of one end of the rotating seat 6 on the outer side of the expansion rod 8. An embedding rotating seat 9 is welded to the outer surface of the telescopic end of the expansion rod 8. In order to detect the outer surface of the milling cutter 12, a detection expansion rod 10 is rotatably connected to the inside of the embedding rotating seat 9. A shielding cover 11 is rotatably connected to the outside of the shielding cover screw port 7. The heights of the expansion rod 8 and the detection expansion rod 10 in the contracted state are less than the depth inside the shielding cover 11. In order to protect the detection mechanism, a milling cutter 12 is fixed to the middle surface of the bottom end of the stable base 1 by bolts. The extended length of the detection expansion rod 10 is greater than the horizontal length from the outer surface of one end of the embedding rotating seat 9 to the outer surface of one end of the milling cutter 12. In order to prevent the detection range of the detection mechanism from exceeding the length of the milling cutter 12 and thus affecting the detection effect, the extended lengths of the expansion rod 8 and the detection expansion rod 10 are greater than the length of the milling cutter 12. One end of the three fixing screws 4 is rotatably connected with a fixing nut 13 inside one hidden vertical groove 3, in order to fix the stable base 1 relative to the external milling machine bed.

[0021] Working principle: First, the operator fixes the stable base 1 to the transmission end of the milling machine through the embedding hole 2 at its top end, and increases the connection stability between the two through the fixing screws 4 and fixing nuts 13 installed through the hidden vertical grooves 3 at both ends of the outer side of the stable base 1. Subsequently, during the subsequent use process, the operator needs to detect the milling cutter 12 at any time to ensure the precision of processing. At that time, the operator flips the rotating seat 6 downward from the inner sides of the side fixing ears 5 welded to both ends of the outer side of the stable base 1. Wait until the extended ends of the two rotating seats 6 are vertically downward. Subsequently, the operator rotates the shielding cover 11 rotatably connected to the bottom end of the rotating seat 6 and removes it from the outside of the shielding cover screw port 7 welded to the middle of the bottom surface of the rotating seat 6.

[0022] Subsequently, the operator pulls down the expansion rod 8 rotatably connected to the inside of the rotating seat 6. Subsequently, the operator rotates the detection expansion rod 10 and rotates the detection expansion rod 10 rotatably connected to its inside with the embedding rotating seat 9 as a support until the detection expansion rod 10 is in a horizontal state. Then, the detection expansion rod 10 is extended until one end of the detection expansion rod 10 is in contact with the outer surface of the milling cutter 12. Subsequently, the operator pulls down. During this period, the detection expansion rod 10 attached to the outer side of the milling cutter 12 will also move downward. If one of the two detection expansion rods 10 shrinks during this period, it proves that the milling cutter 12 is bent, thus affecting the precision of processing. At that time, the milling cutter 12 needs to be replaced. Such a design can make the detection of the milling cutter more convenient and improve the precision and efficiency of processing.

[0023] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
