However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention will be comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art.

Figure 1 FIG1 is a diagram of the first state of the truss-type turning mechanism of the panel turning milling machine in one embodiment of the present invention, in which the worktable is in a horizontal state, which is marked as 0°; Figure 2 for Figure 1 The second state diagram of the truss-type turning mechanism is shown, at this time the workbench is in a vertical state, which is marked as 90°; Figure 3 for Figure 1 Another perspective view of the two first linear drive components 4 and the two second linear drive components 5; Figure 4 for Figure 1 A partial plan view of the truss-type turnover mechanism in the state shown; Figure 5 for Figure 2 A partial plan view of the truss-type turnover mechanism in the state shown; Figure 6 for Figure 1 A schematic diagram of the connection between the first linear drive assembly 4 and the slide 3 in the state shown; Figure 7 for Figure 6 A magnified partial view of Figure 8 Figure 2 The schematic diagram of the connection between the first linear drive assembly 4, the slide 3 and the second linear drive assembly 5 in the state shown. According to one aspect of the present invention, a truss-type turnover mechanism is provided, such as Figures 1 to 8As shown, the truss-type turning mechanism includes a workbench 2, two slides 3, two first linear drive assemblies 4, at least four pillars 1, and two second linear drive assemblies 5. The workbench 2 includes a first side surface and a second side surface disposed opposite each other; the two slides 3 are rotatably connected to the first and second side surfaces of the workbench 2 via a pin; the two first linear drive assemblies 4 are vertically symmetrically disposed on either side of the workbench 2; each of the two first linear drive assemblies 4 is slidably connected to a slide 3 to drive the two slides 3 to perform synchronous linear reciprocating motion within a preset height range; the at least four pillars 1 are vertically fixed to either side of the workbench 2 in two groups along two straight lines; the two second linear drive assemblies 5 are horizontally symmetrically fixed to the upper ends of the two groups of pillars 1; the two second linear drive assemblies 5 are respectively connected to a first linear drive assembly 4 to drive the two first linear drive assemblies 4 to perform synchronous linear reciprocating motion within a preset length range; the two slides 3 and the two first linear drive assemblies 4 are simultaneously driven to perform linear reciprocating motion, thereby causing the workbench 2 to turn within a range of 0 to 90 degrees. When the workbench 2 is in a horizontal state, it is 0°; when the workbench 2 is in a vertical state, it is 90°.
[0033] The truss-type turnover mechanism proposed in the present invention can significantly shorten the loading and unloading cycle of the flap milling machine and greatly improve the working efficiency of the flap milling machine.
[0034] like Figures 5 to 8 As shown, the first linear drive assembly 4 may include a vertical shaft 41, two first guide rails 43, a ball screw pair, and a first servo motor 42. The two first guide rails 43 are symmetrically arranged along the height of the vertical shaft 41 and are slidably connected to one of the slides 3. The ball screw pair is disposed between the two first guide rails 43. The nut in the ball screw pair is fixedly connected to the slide 3. One end of the screw 44 in the ball screw pair is connected to the first servo motor 42 via a coupling 45, and the other end is connected to a bearing. The first servo motor 42 can be fixed to one end of the vertical shaft 41 via a first motor mounting bracket 421. Furthermore, two first sliders 431 are provided on the side of the slide 3 facing the vertical shaft 41. Each of the first sliders 431 is slidably mounted on one of the first guide rails 43. Specifically, the vertical shaft 41 can be made of steel and serve as the base of the first guide rail 43. The two first sliders 431 are slidably mounted on each of the first guide rails 4343. By respectively arranging two first rails on each vertical shaft 41 and connecting a first slider 431 to each of the two first rails, the first slider 431 is engaged with the first guide rail 43, thereby ensuring the stability of the operation of the slide 3, increasing the load that the truss-type turning mechanism can withstand, and significantly improving the safety of the operation process.
[0035] Furthermore, the aforementioned support 1 and vertical shaft 41 can be designed to be relatively low, which not only provides greater rigidity but also reduces the required height space, facilitating workpiece transport. A first servo motor 42 controls the rotation of the lead screw 44, which in turn is driven by a nut to perform linear reciprocating motion along the first guide rail 43. This allows for precise control of the real-time height of the slides 3, ensuring synchronized and stable operation of the two slides 3. Consequently, the two first linear drive assemblies 4 avoid unbalanced loads, are less susceptible to damage to working components, and are therefore safe, reliable, and have a long service life.
[0036] like Figure 3 、 4 As shown in Figures 5 and 8, the second linear drive assembly 5 may include a truss 51, two second guide rails 53, a gear rack pair and a second servo motor 52; the two second guide rails 53 are symmetrically arranged along the length direction of the truss 51 and are slidably connected to the first side of the upper end of the first linear drive assembly 4; the rack 54 in the gear rack pair is arranged between the two second guide rails 53. That is, the second guide rail 53 and the rack 54 are fixed to the inner side of the truss 51. In addition, the gear in the gear rack pair is connected to the second servo motor 52, and the second servo motor 52 can be fixed to the second side of the upper end of the first linear drive assembly 4 through a second motor mounting seat 521. Further, as Figure 8 As shown, two second sliders 531 are provided on the first side of the upper end of the first linear drive assembly 4. The two second sliders 531 are slidably mounted on a second guide rail 53. Specifically, the truss 51 can be made of steel and serve as the base of the second guide rail 53. Two second sliders 531 are provided on the first side of the upper end of the first linear drive assembly 44. The two second sliders 531 are slidably mounted on a second guide rail 53. By providing two second guide rails 53 on the truss 51 and connecting a second slider 531 to each of the two second guide rails 53, the second sliders 531 engage with the upper portion of the second guide rail 53, thereby preventing the first linear drive assembly 4 from tilting during operation and ensuring its operational stability. The rack 54 of the gear rack pair is provided between the two second guide rails 53. The gear in the gear rack pair is connected to the second servo motor 52. The second servo motor 52 can be fixed to the lower side of the first linear drive assembly 4 via a second motor mounting bracket 521. Thus, the second servo motor 52 can drive the first linear drive assembly 4 to perform horizontal linear reciprocating motion along the second guide rail 53. When the two slides 3 and the two first linear drive assemblies 4 are driven to perform linear reciprocating motion simultaneously, the two slides 3 will cause the workbench 2 to flip within a range of 0 to 90 degrees.
[0037] like Figure 6 、 7As shown in Figure 8, a hook 31 is provided on the side of the slide 3 facing away from the first linear drive assembly 4, and the hook 31 cooperates with the pin shaft. Furthermore, a first rotary groove 311 and a second rotary groove 312 can be formed on the hook 31, and the first rotary groove 311 and the second rotary groove 312 are coaxial. Accordingly, the pin shaft can include a first rotary part and a second rotary part coaxially connected. The first rotary part cooperates with the first rotary groove 311, and the second rotary part cooperates with the second rotary groove 312. In this way, the workbench 2 can be prevented from shaking when flipping, and the stability and safety of loading and unloading of the flip milling machine can be effectively guaranteed.
[0038] Furthermore, the workbench 2 includes a third side surface and a fourth side surface that are oppositely disposed and perpendicular to the two straight lines, and the distances from the line connecting the two pins to the third side surface and the fourth side surface are unequal. This ensures that the workbench 2 can be smoothly flipped to 90 degrees, allowing the workpiece on the workbench to be processed.
[0039] In summary, the truss-type turning mechanism proposed in this invention can significantly shorten the loading and unloading cycle of a flap milling machine, greatly improving its operating efficiency. Furthermore, this truss-type turning mechanism can accommodate large-sized worktables (2), allowing the flap milling machine to process a wider range of part sizes. Driven by a servo motor, this truss-type turning mechanism eliminates the risk of hydraulic oil leakage and allows precise control of the turning angle of the worktable (2), resulting in high operational reliability.
[0040] In addition, the present invention also provides a milling machine with a turning plate, which includes the truss-type turning mechanism described above. Figures 1 to 8 It has been described, so it will not be repeated here. Those skilled in the art should understand that the truss-type turning mechanism is only a part of the flap milling machine. Since the other structures of the flap milling machine are not the inventive point of the present invention, the existing technology can be used, so it will not be described in detail here. The truss-type turning mechanism in the present invention has a strong load-bearing capacity, and the workbench 2 therein can be turned around the pin in the range of 0 to 90°, which can significantly shorten the loading and unloading cycle of the flap milling machine, improve the working efficiency of the flap milling machine, and is not easy to damage the workpiece. In addition, the truss-type turning mechanism can be adapted to a large-sized workbench 2, so that the flap milling machine can process parts with a wider range of sizes. The operation of the truss-type turning mechanism is driven by a servo motor. Not only is there no risk of hydraulic oil leakage, but the turning angle of the workbench 22 can be accurately controlled, and the working reliability is high.
[0041] In summary, the flap milling machine proposed in the present invention can significantly shorten the loading and unloading cycle of the flap milling machine by providing the truss-type turning mechanism, thereby greatly improving the working efficiency of the flap milling machine.
[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
