[0022] The following is combined with Figure 1-3This application is described in further detail.

[0023] The present application embodiment discloses a lifting structure of a rocker milling machine. Figure 1-3 A lifting structure of a rocker milling machine includes a column 1 installed on a base, and the column 1 is used to support and install the overall structure; a cavity is opened on the column 1, and a lifting component 4 is installed in the cavity. The lifting component 4 includes a screw 402 rotatably installed in the column 1, and a threaded sleeve 403 is threadedly installed on the screw 402. The threaded sleeve 403 is driven up and down by the screw 402, and then a guide component 5 moves up and down. The threaded sleeve 403 is installed on the guide component 5, and the guide component 5 includes a slider 501 installed on the column 1, and a rocker arm 2 is installed on the slider 501. A machine head 3 is installed at the end of the rocker arm 2, and a tool is loaded through the machine head 3 to process parts. A partition component 6 is installed between the column 1 and the guide component 5, and the partition component 6 is used to isolate waste chips from entering the cavity.

[0024] Reference Figure 2 A slot is provided on the side wall of the cavity, and the threaded sleeve 403 is slidably installed in the slot. The upper end of the screw rod 402 passes through the column 1 and is connected to a driving motor 401. The driving motor 401 drives the screw rod 402 to rotate, thereby driving the threaded sleeve 403 and the slider 501 to move up and down.

[0025] Reference Figure 3 The partition assembly 6 includes a protective curtain 601 installed on both sides of the groove on the column 1, the protective curtain 601 is between the slider 501 and the column 1, and a Velcro 602 is installed on the inner side of the protective curtain 601. The two Velcros 602 are fitted together to form a closed surface. The protective curtain 601 is made of flexible material, and the threaded sleeve 403 is located on the inner side of the two Velcros 602.

[0026] Reference Figure 2 Brackets 502 are installed on the upper and lower sides of the threaded sleeve 403 on the slider 501. Two relatively installed clamping rollers 503 are installed on the side of the bracket 502 close to the slider 501. The two Velcros 602 are rolled on the inner sides of the two clamping rollers 503. The Velcros 602 are rolled and squeezed by the clamping rollers 503, so that the Velcros 602 on both sides are fitted and closed, and the protective curtain 601 is used to cover the groove to prevent debris from entering the column 1 and affecting the operation of the screw 402 and the threaded sleeve 403.

[0027] Reference Figure 3 The bracket 502 includes a connecting column 5021 installed between two Velcros 602. The Velcros 602 are separated by the connecting column 5021 to facilitate the passage of the screw 402. A T-shaped plate 5022 is installed at the end of the connecting column 5021, and the pressure roller 503 is rotatably installed on the T-shaped plate 5022 to reduce the wear of the pressure roller 503 on the Velcro 602.

[0028] The implementation principle of the lifting structure of a rocker milling machine in the embodiment of the present application is:

[0029] When the drive motor is in an inactive state, the screw 402 is stationary, and the protective curtains 601 and Velcro 602 on the upper and lower sides of the slider 501 are closed to close the slot to prevent external foreign matter from entering. When the height of the rocker arm needs to be adjusted, the drive motor 401 is activated, and the drive motor 401 drives the screw 402 to rotate. The rotation of the screw 402 causes the threaded sleeve 403 to move up and down in the slot. The movement of the threaded sleeve 403 drives the slider 501 to move up and down as a whole, thereby changing the height of the rocker arm 2 and the machine head 3. During the lifting process, due to the threaded sleeve 403 When the threaded sleeve 403 moves, it will pass between the protective curtain 601 and the Velcro 602. When the threaded sleeve 403 moves, it will drive the connecting column 5021 to move, thereby separating the Velcro 602 on both sides. After the threaded sleeve 403 passes between the protective curtain 601 and the Velcro 602, the two Velcro 602 are re-fitted under the rolling and squeezing of the clamping roller 503 to close the groove. This process ensures that during the lifting and lowering of the rocker arm, the protective curtain 601 can always cover the groove to prevent waste or other foreign matter from entering the cavity and affecting the normal operation of the screw 402 and the threaded sleeve 403.
