Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, by Figure 1-4 The utility model includes a milling cutter with an automatic extension function, including a fixed support 1, a groove 2 is opened on the inner wall of the fixed support 1, a through groove 3 is opened on the inner wall of the fixed support 1, a spray gun base 4 is fixedly connected to the bottom of the fixed support 1 and the outer side close to the through groove 3, a high-pressure nozzle 5 is fixedly connected to the outer side of the spray gun base 4, an electric push rod 6 is fixedly connected to the inner side of the groove 2, a fixed end of the electric push rod 6 is fixedly connected to the inner wall of the groove 2, a movable end of the electric push rod 6 is fixedly connected to a slider 7, a slider 7 is fixedly connected to the bottom of the electric push rod 6, the slider 7 is fitted with the inner wall of the groove 2, the electric push rod 6 is used to push the slider 7 to move, and a fastening screw 9 is threadedly connected to the inner wall of the slider 7, and the size of the fastening screw 9 is consistent with the size of the thread groove 10. The sizes are adapted, the fastening screw 9 is threadedly connected with the thread groove 10, the bottom of the slider 7 is fitted with a connecting block 8, the inner wall of the connecting block 8 is provided with a thread groove 10, the inner wall of the connecting block 8 is fixedly connected with an electromagnet 11, the electromagnet 11 is electrically connected to an external power supply, the opposite surfaces of the electromagnet 11 and the magnetic block 16 are opposite, the inner wall of the connecting block 8 is elastically connected with a limiting block 15, the inner wall of the limiting block 15 is fixedly connected with a magnetic block 16, the inner wall of the fixed support 1 and close to the groove 2 are provided with limiting grooves 14, the limiting grooves 14 are symmetrically distributed on the inner wall of the fixed support 1, the size of the limiting block 15 is adapted to the size of the limiting grooves 14, the bottom of the connecting block 8 is fixedly connected with a cutter head 13, and the inner wall of the cutter head 13 is provided with a slide groove 12.

[0022] Working principle: When the milling cutter is in use, the fixed support 1 is driven to rotate by the driving device inside the machine, so that the cutter head 13 processes the component. During this process, the metal debris processed by the cutter head 13 on the component will move up along the inner side of the slide 12 when the cutter head 13 moves down, avoiding the metal debris from being distributed around the cutter head 13, thus ensuring the product quality of the component processing;

[0023] After the processing is completed, the water pump inside the machine is turned on to pump water to the inside of the through groove 3, and then the debris on the cutter head 13 is washed away by the spray gun base 4 and the high-pressure nozzle 5, so that the cutter head 13 is cleaned, which facilitates the reuse of the cutter head 13 and improves the use accuracy of the cutter head 13;

[0024] When it is necessary to process the component to different depths, by connecting the external power supply electrically connected to the electromagnet 11, the electromagnet 11 will have magnetism at this time. Since the magnetism of the opposite surfaces of the electromagnet 11 and the magnetic block 16 is opposite, the electromagnet 11 will attract the magnetic block 16 at this time. Under the action of the attraction, the magnetic block 16 will drive the limit card block 15 to separate from the limit card slot 14, so that the limit card block 15 enters the inner side of the connecting block 8. At this time, the staff controls the extension or shortening of the electric push rod 6 to adjust the length of the cutter head 13. After adjusting to the appropriate position, the external power supply electrically connected to the electromagnet 11 is disconnected. At this time, the limit card block 15 will be engaged with the limit card slot 14 under the action of elastic force, and then the cutter head 13 is fixed, so that when processing components to different depths, it is achieved that manual replacement of milling cutters of different models is avoided, which saves time and effort, improves the processing efficiency of the milling cutter on the component, is conducive to the use of the milling cutter, and achieves a single model of milling cutter can process different depths, eliminating the limitations of the use of the milling cutter;

[0025] When the milling cutter needs to be replaced, through the above steps, the extension of the electric push rod 6 is controlled to push the slider 7 out of the groove 2. At this time, the staff turns the fastening screw 9 to separate the fastening screw 9 from the threaded groove 10, thereby separating the slider 7 from the connecting block 8, and then separating the milling cutter from the machine, which is convenient for maintenance of the milling cutter and increases the service life of the milling cutter.
