[0002] Milling machine is a metal processing machine tool. In the fields of industrial production, artistic creation and hand-made, gantry milling machine has important applications. Milling machine is a mechanical equipment used to process metal, plastic, wood and other materials. Its main purpose is to perform engraving, milling, cutting, grooving and other processing operations on the surface of the workpiece to achieve precise control of the shape, size and surface quality of the workpiece.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: an adjustable gantry milling machine, including a body 1 and a moving platform 2, a support plate 3 is fixedly connected to one side of the moving platform 2, a first motor 4 is fixedly connected to the bottom of the support plate 3, a rotating handle 5 is fixedly connected to the output end of the first motor 4, a first connecting column 6 is fixedly connected to the bottom of the rotating handle 5, a first connecting column 6 is rotatably connected to one end of the first connecting column 6, a second connecting column 8 is rotatably connected to the inside of the first rotating column 7, a first connecting ring 9 is fixedly connected to the outer wall of the second connecting column 8, a connecting rod 10 is fixedly connected to the outer wall of the first connecting ring 9, a second connecting ring 11 is fixedly connected to one side of the connecting rod 10, a fixed plate 12 is fixedly connected to the bottom of the support plate 3, the second connecting ring 11 is rotatably connected to one side of the fixed plate 12, a driving assembly is arranged at the bottom end of the first rotating column 7, the driving assembly includes a second motor 13, the top of the second motor 13 is fixedly connected to the bottom end of the first rotating column 7, and a milling cutter 14 is fixedly connected to the output end of the second motor 13.

[0034] Specifically, when it is necessary to adjust the processing angle of the milling cutter 14, first, the power output by the first motor 4 drives the rotating handle 5 to start rotating, and transmits force to the first connecting column 6 at the bottom, thereby starting the movement of the first rotating column 7 connected at the bottom, and the rotation of the first rotating column 7 drives the second connecting column 8 connected internally, which is converted into the rotation of the first connecting ring 9 connected to the outer wall again, and through the movement of the connecting rod 10, the second connecting ring 11 is driven to rotate on the inner wall of the fixed plate 12, causing the first rotating column 7 to rotate and swing. At the same time, the movement of the first rotating column 7 also drives the second motor 13 connected to the bottom to start working, and the second motor 13 directly controls the movement of the milling cutter 14. When the required processing angle is adjusted to the desired position, the milling cutter 14 is stopped in position by turning off the first motor 4, and then the second motor 13 drives the milling cutter 14 to rotate through the output end, thereby performing the processing operation, effectively realizing the flexible adjustment of the angle of the milling cutter 14, and providing greater flexibility and precision for the processing technology.

[0035] Reference Figure 1 , Figure 4 and Figure 5A fixing frame 15 is fixedly connected to the side wall of the body 1, a support frame 16 is fixedly connected to one side of the fixing frame 15, an electric push rod 17 is fixedly connected to one side of the support frame 16, a rack 18 is fixedly connected to the output end of the electric push rod 17, the rack 18 is slidably connected inside the fixing frame 15, a first gear 19 is rotatably connected inside the fixing frame 15, the first gear 19 is meshed with the rack 18, one end of the first gear 19 is rotatably connected to a threaded column 23, an outer wall of the threaded column 23 is threadedly connected to a sleeve 24, the sleeve 24 is slidably connected inside the fixing frame 15, and one end of the sleeve 24 is fixedly connected to a pressing plate 25.

[0036] Specifically, when the workpiece needs to be fixed, first, the workpiece is placed on the top of the machine body 1, and then the rack 18 starts to move through the force output by the electric push rod 17, which causes the first gear 19 meshing therewith to rotate, thereby driving the threaded column 23 connected to one end to rotate inside the fixing frame 15. As the threaded column 23 moves, the sleeve 24 on the outer wall slides to the outside of the fixing frame 15, and at the same time drives the pressure plate 25 connected to one end thereof to move, pressing it against the side of the workpiece, thereby achieving a driving effect.

[0037] Reference Figure 1 , Figure 4 and Figure 5 A second gear 20 is rotatably connected inside the fixed frame 15, and the second gear 20 is meshed with the first gear 19. One end of the second gear 20 is rotatably connected to a second rotating column 21, and the second rotating column 21 is rotatably connected to the inside of the fixed frame 15. An eccentric wheel 22 is rotatably connected to the outer wall of the second rotating column 21.

[0038] Specifically, at the same time, the first gear 19 also pushes the second gear 20 meshing therewith to rotate, and the second rotating column 21 connected to the second gear 20 begins to rotate in the fixed frame 15. The movement of the second rotating column 21 is transmitted to the eccentric wheel 22 connected to the outside. Due to the eccentric connection between the eccentric wheel 22 and the second rotating column 21, when the eccentric wheel 22 rotates, it applies pressure on the workpiece, further stabilizing the position of the workpiece, so that the milling machine can flexibly adapt to workpieces of different sizes, ensuring stability and safety during the processing.

[0039] Working principle: when it is necessary to adjust the processing angle of the milling cutter 14, firstly, the rotating handle 5 is driven to rotate through the output end of the first motor 4, and the rotating handle 5 is subjected to force to drive the first connecting column 6 at the bottom to rotate, and the first connecting column 6 is subjected to force to drive the first rotating column 7 connected to the bottom end to rotate, and the first rotating column 7 is subjected to force to drive the second connecting column 8 connected inside to rotate, and the second connecting column 8 is subjected to force to drive the first connecting ring 9 connected to the outer wall to rotate, and the first connecting ring 9 is subjected to force to drive the connecting rod 10 connected to the outer wall to move, and the connecting rod 10 is subjected to force to drive the second connecting ring 11 on one side to rotate on the inner wall of the fixed plate 12, so that the first rotating column 7 rotates and swings, and at the same time, the first rotating column 7 is subjected to force to drive the second motor 13 connected to the bottom end to move, and the second motor 13 drives the milling cutter 14 to move. When it is adjusted to the required angle, the milling cutter 14 is stopped by turning off the first motor 4, and then the milling cutter 14 is driven to rotate for processing through the output end of the second motor 13, so that the milling cutter 14 can be adjusted without The same angle effect, when the workpiece needs to be fixed, the workpiece is first placed on the body 1, and then the rack 18 is driven to move by the output end of the electric push rod 17. The rack 18 is forced to drive the first gear 19 meshing with it to rotate, and the first gear 19 is forced to drive the threaded column 23 connected at one end to rotate inside the fixing frame 15. The threaded column 23 drives the sleeve 24 of the outer wall to slide outside the fixing frame 15. The sleeve 24 is forced to drive the pressure plate 25 connected at one end to move, and push it against the side of the workpiece to fix it. At the same time, the first gear 19 will also drive the second gear 20 meshing with it to rotate, and the second rotating column 21 connected to the second gear 20 is forced to rotate inside the fixing frame 15. The second rotating column 21 is forced to drive the eccentric wheel 22 connected to the outer wall to rotate. Due to the eccentric connection between the eccentric wheel 22 and the second rotating column 21, the eccentric wheel 22 will press on the top of the workpiece when it rotates to further fix it, thereby achieving the effect of fixing workpieces of different sizes.
