DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0025] Reference Figure 1-2 , which is the first embodiment of the utility model, and provides an aluminum profile CNC end milling machine, including a support assembly 100 and a drive assembly 200, wherein the drive assembly 200 is fixed to the support assembly 100, and the drive assembly 200 includes a connecting shaft 202 and a milling cutter portion 203, wherein the milling cutter portion 203 is movably plugged with the bottom of the connecting shaft 202, and a disassembly assembly 300 is provided on the outer side surface of the milling cutter portion 203;

[0026] The disassembly assembly 300 includes a sleeve 301 sleeved on the outer wall of the milling cutter part 203, a square frame 302 is fixed to the sleeve 301, a protrusion 306 is fixed to the inner wall of the square frame 302, a sliding plate 305 is slidably connected to the protrusion 306, a straight rod 303 is penetrated and connected to the sliding plate 305, and the end surface of the straight rod 303 extends to the inner wall of the square frame 302, and a spring 304 is elastically connected between the outer side of the straight rod 303 and the inner side of the sliding plate 305;

[0027] Specifically, the socket connection between the sleeve 301 and the milling cutter part 203 enables the direct disassembly of the milling cutter part 203. Meanwhile, the sliding connection between the sliding plate 305 and the convex block 306 helps the sleeve 301 to better contact the deformed milling cutter part 203, thereby improving the disassembly efficiency and enabling the deformed milling cutter part 203 to be quickly disassembled, reflecting the practicality of the device. In addition, the socket connection between the spring 304 and the straight rod 303 enables the thrust of the sliding plate 305 to be immediately absorbed and stored, while reducing the wear of the sliding plate 305 and ensuring the clamping efficiency between the sleeve 301 and the deformed milling cutter part 203, thus improving the disassembly efficiency.

[0028] The sliding plate 305 is provided with a groove, and a column 307 is fixed inside the groove. The column 307 is rotatably connected to a connecting rod part 308. The center of the connecting rod part 308 is hinged to a first hinge column 309. An inclined tooth part 310 is fixed inside the square frame 302. The inclined tooth part 310 engages with a bent claw 311. A second hinge column 312 is fixed to the end face of the connecting rod part 308, and the second hinge column 312 is rotatably connected to the bent claw 311.

[0029] Furthermore, the connection between the first hinge column 309 and the connecting rod part 308 enables the connecting rod part 308 to rotate stably, which is beneficial for the sleeve 301 to more flexibly clamp the milling cutter part 203. Meanwhile, the engagement between the bent claw 311 and the inclined tooth part 310 enables the sleeve 301 to stably clamp the milling cutter part 203 with different deformation amounts through the form of long-distance displacement engagement.

[0030] In summary, through the socket connection between the spring 304 and the straight rod 303 and the elastic connection of the sliding plate 305, the thrust of the sleeve 301 is absorbed and stored, reducing the problem of jitter during clamping of the sleeve 301. Through the engagement between the bent claw 311 and the inclined tooth part 310, the deformation amount of the milling cutter part 203 is further converted into the displacement amount of engagement, which is intuitive and efficient. Adjusting the engagement tooth pitch can ensure the high clamping efficiency of the sleeve 301 for the deformed milling cutter part 203. Through the articulated rotation of the connecting rod part 308 and the first hinge column 309, the adjusted displacement amount is fed back to the sleeve 301, completing a relatively complete disassembly and replacement process for the milling cutter part 203. Embodiment

[0031] Refer to Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant components for realizing the continuous operation of the milling machine.

[0032] Specifically, there is a pull rod 313 on the top of the sliding plate 305. The pull rod 313 is a right-angled steel rod formed integrally. The driving assembly 200 further includes a driving motor 201 fixed to the top of the connecting shaft 202. The driving motor 201 is fixedly connected to the machine frame 103 through a triangular plate, and the bottom of the machine frame 103 is fixedly connected to the base table 101.

[0033] The support assembly 100 where the frame 103 is located further includes a control box 104. The control box 104 is fixed to the side of the frame 103. A milling slide 102 is slidably connected to the top of the base 101, and the milling slide 102 is electrically connected to the control box 104.

[0034] During use, first, the base 101 and the frame 103 are combined and set. Then, the control box 104 is assembled on the side of the frame 103 and started. Under the action of electrical connection and the support of the base 101, the milling slide 102 operates stably. When the milling cutter part 203 needs to be replaced, the driving force of all driving parts is cut off, the pull rod 313 is pulled, and the disassembly assembly 300 immediately plays a role to help the sleeve 301 approach and disassemble the milling cutter part 203.

[0035] In summary, by controlling the electrical connection between the control box 104 and the milling slide 102, the milling process can run continuously. At the same time, the fixing of the driving motor 201 to the connecting shaft 202 can provide a sufficient power source for the milling cutter part 203, ensuring the normal milling of the milling cutter part 203. Embodiment

[0036] Referring to Figure 3-4 , this is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant components for the stable meshing and clamping effect of the helical tooth part and for ensuring the stability of the overall device.

[0037] Specifically, the helical tooth part 310 includes two groups of inclined surface teeth, and the sum of the inclination angles of the two groups of inclined surface teeth is a right angle. A stabilizing column is provided at the bottom of the base 101, and there are multiple stabilizing columns, which are distributed at the four corners of the base 101.

[0038] In summary, by providing the stabilizing columns at the four corners of the base 101, the stability of the overall device is ensured. Further, the setting of the complementary angles of the inclined surface teeth can ensure the precise meshing of the inclined surface teeth. Furthermore, the approaching and disassembly efficiency of the sleeve 301 and the deformed milling cutter part 203 is improved, highlighting the rapid disassembly ability of the overall device.
