[0028] The following specific embodiment is only the explanation of the utility model, and it is not the limitation of the utility model, and the person skilled in the art can make the modification of no creative contribution according to the need after reading the present specification, but as long as in the utility model's right claim range is protected by patent law.

[0029] The present scheme is realized through the following technical means:

[0030] The structure of the detachable adjustable milling cutter given in this example mainly includes a rod-shaped main body section 1 for connecting with the driving device and a detachable functional section 2 detachably mounted at the front end of the rod-shaped main body section 1. The outer surfaces of the rod-shaped main body section 1 and the detachable functional section 2 are respectively formed with helical blade parts 3, and the helical directions of the blade parts 3 on the rod-shaped main body section 1 and the detachable functional section 2 are opposite. When the rod-shaped main body section 1 and the detachable functional section 2 are integrally connected, the driving motor can be used to rotate the two parts as a whole to mill the board. Similar to the structure of the milling cutter disclosed in the Chinese utility model patent document with the application number CN201820111507.8, the local milling of the relatively fragile and easily damaged board product can be realized, and the uniform stress on both sides can be realized to avoid the fragmentation and damage of the processed board.

[0031] A key technical point of the milling cutter product given in the embodiment scheme of the present application is that different helical blade parts 3 on different milling cutters are placed on different two sections, so that the processing form of the milling cutter can be freely changed according to the actual milling requirements without the need for overall disassembly and replacement of the milling cutter. The advantages of this structure are that the protection of the board is realized, and sometimes the accumulation direction of the debris generated by milling needs to be controlled at the local position, so the detachable functional section 2 mounted at the front end of the milling cutter can be easily removed. At the same time, since the milling cutter is not disassembled and replaced as a whole, the installation and positioning of the cutter do not need to be adjusted and corrected, so the efficiency of the entire milling process is improved.

[0032] In the present application, in order to realize the detachable connection and fixation between the rod-shaped main body section 1 and the detachable functional section 2, a threaded screw structure 4 is selected. Specifically, the structure is shown in the attached drawings Figure 2As shown, it comprises a threaded hole 401 on the rod-shaped main body segment 1 and a threaded connecting segment 402 on the detachable functional segment 2, the threaded connecting segment 402 can be screwed into the threaded hole 401 in the state of opposite to the central axis of the threaded hole 401. In addition, in this structure, the direction of the threaded connecting segment 402 screwed into the threaded hole 401 is opposite to the overall operation work rotation direction of the milling cutter. The reason for this design is that even if the tightening torque between the two segments is not enough in the initial state, as the milling cutter processes the plate, the resistance from the plate on the previous detachable functional segment 2 will continue to rotate in the screwing direction, preventing the two segments from loosening.

[0033] Further preferably, a spacing adjusting pad 5 is arranged between the inner end face of the threaded hole 401 and the threaded connecting segment 402 to adjust the spacing distance between the blade part 3 on the rod-shaped main body segment 1 and the blade part 3 on the detachable functional segment 2. The design of this structure is that the inventor considers that when milling some fragile and vulnerable plates, it is necessary to leave a non-processing area on the processing surface while avoiding damage. At this time, the end face of the detachable functional segment 2 can be supported by the spacing adjusting pad 5 made of a hard metal such as aluminum alloy inside the threaded hole 401 to prevent it from continuing to rotate and move inward during milling, thereby ensuring that the reserved gap area is constant during processing.

[0034] Further, the inventor considers that in order to achieve the above-mentioned effect of preventing plate damage, attention should also be paid to the fact that the contact area of the blade part 3 on both sides with the plate should be as consistent as possible or even the same. Only in this case, the blade parts 3 with different rotation directions on both sides can balance the local force on the plate during cutting. At this time, the blade parts 3 on different functional segments of the milling cutter should be made with the same length, and the blade parts 3 on both sides should be in full contact with the plate. In order to achieve this processing state, the center line position between the blade parts 3 on both sides should be as coincident as possible with the center line position of the processing area. Therefore, with reference to the drawings, the center line position of the blade part 3 on the detachable functional segment 2 is arranged to be coincident with the center line position of the processing area of the plate. Figure 3The structure state given, in this embodiment, the rod-shaped body section 1 and the rod-shaped body section 1 are provided with a scale line 6 for indicating the center line between the two side blade parts 3. The meaning of the scale line 6 is that in different working states, the thickness of the aforementioned spacing adjusting pad 5 arranged in the threaded hole 401 is different; therefore, according to the actual spacing distance, the scale line 6 at different positions should be used as the center line of the milling cutter during processing and adjusted with the center line measured and marked on the plate.

[0035] Further, in order to ensure that the detachable adjustable plate milling cutter is stably and reliably connected and fixed with the head part of the driving device at the rear end, a clamping and fixing section 7 is formed at the rear end of the rod-shaped body section 1 by cutting processing. At the same time, in order to ensure that the milling cutter with the multi-section adjustable structure has sufficient strength during processing of the plate, the rod-shaped body section 1 and the rod-shaped body section 1 are made of ceramic material, and the blade part 3 accounts for 20%-40% of the overall diameter of the milling cutter, so as to ensure the durability of the cutter.

[0036] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
