[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3One embodiment of this utility model is a high-precision milling machine tool for ship structural components. The adaptive clamping machine tool includes a machine tool body 1, and a rotating base 8, a placement plate 15, and a clamping block 18 disposed on the machine tool body 1. The placement plate 15 is used to support the structural component to be processed, and the clamping block 18 is used to clamp and fix the structural component. The machine tool also includes a cylinder 13, a support block 14, a rotating plate 16, and a rotating rod 17. The rotating rod 17 is vertically installed on the rotating base 8 and provides a rotation center for the rotating plate 16. The rotating plate 16 is rotatably disposed on the rotating rod 17.

[0029] The cylinder 13 serves as a power source, with its piston rod end fixedly connected to the support block 14. The support block 14 is fixedly connected to the rotating plate 16, thereby converting the linear motion of the cylinder 13 into the rotational motion of the rotating plate 16. The lower surface of the rotating plate 16 is provided with a limiting groove 25 for guiding the clamping block 18. One end of the clamping block 18 is slidably embedded in the limiting groove 25. The rotation of the rotating plate 16 drives the clamping block 18 to move, thereby achieving adaptive clamping of structural parts of different sizes.

[0030] The lower surface of the rotating plate 16 is provided with a limiting groove 25 extending radially or along a specific curve, and a limiting block 26 is integrally formed on the rotating plate 16. The limiting block 26 is used to limit the rotation range of the rotating plate 16. The rotating plate 16 is rotatably connected to the rotating rod 17 through its central hole. At the same time, the rotating plate 16 is also fixedly connected to the support block 14 by bolts. The movement of the support block 14 directly drives the rotating plate 16 to rotate.

[0031] Meanwhile, the upper end of the clamping block 18 is provided with a guide structure that matches the shape and size of the limiting groove 25. In the assembled state, the guide structure of the clamping block 18 slides within the limiting groove 25 of the rotating plate 16. When the piston rod of the cylinder 13 extends or retracts, the linear motion generated by it pushing the support block 14 is transmitted to the rotating plate 16 through a fixed connection and converted into the rotational motion of the rotating plate 16 around the rotating rod 17. As the rotating plate 16 rotates, the limiting groove 25 on it drives and guides the clamping block 18 embedded therein, so that the clamping block 18 simultaneously rotates and slides radially along the limiting groove 25. This groove-rail cooperation structure between the rotating plate 16 and the clamping block 18 converts a single drive input into a compound clamping action, ensuring that multiple clamping blocks 18 can synchronously approach and clamp the structural parts to be processed from different directions, thereby realizing the adaptive clamping function for workpieces of different sizes.

[0032] In order to provide a more stable and reliable structural support for the clamping block 18, the machine tool body 1 is also provided with a clamping body 11 for supporting the clamping block 18. The clamping body 11 provides a solid mounting foundation for the clamping block 18 to withstand the force during the clamping process.

[0033] To facilitate the collection and cleaning of waste chips generated during processing, a waste chip hole 12 is provided on the machine tool body 1 above the waste chip box 10. The waste chip box 10 is detachably installed on the lower part of the machine tool body 1. A slider 7 is fixed on the waste chip box 10, and a corresponding sliding groove 19 is provided on the machine tool body 1 to slide with the slider 7. To achieve quick fixation of the waste chip box 10, an iron block 21 is provided on the waste chip box 10. A magnetic hole 20 corresponding to the position of the iron block 21 is provided on the machine tool body 1. A magnet 24 is installed in the magnetic hole 20, and the waste chip box 10 is attracted and fixed by magnetic attraction. To further ensure accurate positioning during installation, a positioning pin 22 is also provided on the waste chip box 10. A positioning hole 23 that cooperates with the positioning pin 22 is provided on the machine tool body 1. A second handle 9 is also connected to the waste chip box 10 to facilitate the operator to pull out the waste chip box 10.

[0034] In order to perform milling of structural parts, a rotating shaft 4 is rotatably mounted on the machine tool body 1. The working end of the rotating shaft 4 is connected to a milling cutter 3. At the same time, the machine tool is also equipped with a control panel 6, which is electrically connected to the cylinder 13 and the rotating shaft 4 respectively, and is used to issue operating commands. In order to ensure operational safety and facilitate observation, an observation door 2 can also be opened and closed on the machine tool body 1. The observation door 2 is equipped with a first handle 5.

[0035] Working principle: When it is necessary to clamp structural parts of different sizes, the cylinder 13 is activated through the control panel 6. The extension and retraction of the cylinder 13 pushes the support block 14, which is fixedly connected to it, to move. Since the support block 14 is fixedly connected to the rotating plate 16, the linear movement of the support block 14 drives the rotating plate 16 to rotate around the rotating rod 17, which is vertically installed on the rotating base 8. As the rotating plate 16 rotates, the limiting groove 25 on it will drive and guide the clamping block 18 embedded therein, so that the clamping block 18 gradually approaches and clamps the structural parts fixed on the placement plate 15 under the support of the clamping body 11. At the same time, the limiting block 26 on the rotating plate 16 plays the role of limiting the rotation range. Through this linkage between the cylinder 13, the support block 14, the rotating plate 16 and the clamping block 18, the problems of cumbersome adjustment and poor adaptability of the clamping device in the prior art are solved. After clamping is completed, the observation door 2 is closed, and the rotating shaft 4 is controlled to rotate through the control panel 6, which drives the milling cutter 3 to perform milling on the structural parts.

[0036] When it is necessary to clean up the waste chips that fall into the waste chip box 10 through the waste chip hole 12 during processing, the operator holds the second handle 9 and pulls the waste chip box 10 outward to overcome the magnetic attraction between the magnet 24 and the iron block 21, and to make the positioning pin 22 disengage from the positioning hole 23. The waste chip box 10 can then slide smoothly out along the slide groove 19 on the machine tool body 1 through the sliding cooperation between the slider 7 and the slide groove 19, the magnetic attraction between the iron block 21 and the magnet 24 in the magnetic hole 20, and the positioning cooperation between the positioning pin 22 and the positioning hole 23, the problems of complicated disassembly and assembly and inconvenient cleaning of the waste chip box 10 in the prior art are solved.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
