[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Refer to Figures 1 - 3 As shown in the figure, an embodiment provided by the present invention: an automatic processing center workpiece turnover device includes a workbench 1. A placing plate 2 is fixedly connected to the upper part of the workbench 1. The workbench 1 fixes the placing plate 2. Vertical plates 3 are fixedly connected to both sides of the upper part of the placing plate 2. The placing plate 2 fixes the two vertical plates 3. A cushion plate 4 is fixedly connected to the left part of one vertical plate 3. A motor 5 is fixedly connected to the upper part of the cushion plate 4. The cushion plate 4 provides a stable placement platform for the motor 5. The output end of the motor 5 is fixedly connected to a driving gear 6. A rotating shaft 8 is rotatably connected to the inside of the vertical plate 3. One end of the rotating shaft 8 is fixedly connected to a driven gear 7. The driving gear 6 and the driven gear 7 are meshed with each other. The other end of the rotating shaft 8 is fixedly connected to a fixed seat 14. The rotating shaft 8 is used to drive the fixed seat 14 to rotate. One end of a rotating rod 21 is fixedly connected to the right part of the fixed seat 14. The other end of the rotating rod 21 is fixedly connected to a rotating plate 9. The rotating rod 21 is used to drive the rotating plate 9 to rotate. Limiting components are fixedly connected to the four surrounding parts of the left part of the rotating plate 9. The limiting components are used to limit the rotating shaft 8. The limiting components include connecting rods 10. One end of each of the plurality of connecting rods 10 is fixedly connected to the left part of the rotating plate 9. The other end of the connecting rod 10 is fixedly connected to a connecting plate 11. Limiting posts 12 are fixedly connected to the left parts of the two connecting plates 11. A limiting ring 13 is fixedly connected to the right part of the right vertical plate 3. The limiting post 12 is slidably connected to the inside of the limiting ring 13. The limiting post 12 is used to limit the rotating plate 9. The rotating rod 21 is rotatably connected to the inside of the right vertical plate 3. The fixed seat 14 is rotatably connected to the inside of the placing plate 2.
[0024] After the workpiece is clamped and fixed, the motor 5 is started. The output end of the motor 5 starts to work, driving the rotation of the driving gear 6. With the rotation of the driving gear 6, the driven gear 7 meshed with it also starts to rotate. The rotation of the driven gear 7 drives the rotation of the rotating shaft 8. The rotation of the rotating shaft 8 causes the fixed seat 14 to start rotating. When the fixed seat 14 rotates, it drives the rotating rod 21 to rotate synchronously. The rotation of the rotating rod 21 further drives the rotation of the rotating plate 9 and the connecting rod 10. The rotation of the connecting rod 10 causes the connecting plate 11 and the limiting column 12 to start rotating. The limiting column 12 slides inside the limiting ring 13. This sliding, under the action of the limiting column 12, significantly improves the stability of the fixed seat 14 during rotation. As the fixed seat 14 continues to rotate, the workpiece inside it also starts to flip.
[0025] Refer to Figure 2 and Figure 4 Around the outside of the fixed seat 14, cylinders 15 are fixedly connected. The output ends of the multiple cylinders 15 are all fixedly connected with push plates 16. The cylinders 15 are used to push the push plates 16 to move. On the upper parts of the multiple push plates 16, moving seats 17 are fixedly connected. On the relative sides of the multiple moving seats 17, one ends of positioning rods 18 are fixedly connected. The other ends of the multiple positioning rods 18 are all fixedly connected with clamping members 19. The clamping members 19 are used to fix the workpiece. Inside the fixed seat 14, a fixing plate 22 is fixedly connected. The multiple push plates 16 are all slidably connected inside the fixing plate 22. The multiple moving seats 17 are all slidably connected on the upper part of the fixing plate 22. The multiple clamping members 19 are all slidably connected inside the fixed seat 14. Inside the multiple moving seats 17, clamping grooves 20 are formed. The clamping grooves 20 are engaged with the fixed seat 14. After the clamping grooves 20 are engaged with the fixed seat 14, it plays a role in limiting the moving seats 17.
[0026] The cylinders 15 are started. The output ends of the cylinders 15 start to act, pushing the push plates 16 to move along a predetermined track. During the movement of the push plates 16, they drive the moving seats 17 to move along the corresponding guide rails or chutes. The movement of the moving seats 17 will drive the positioning rods 18 to move along their set paths. During the movement of the positioning rods 18, they will push the multiple clamping members 19 to approach each other, causing the clamping members 19 to gradually move towards the workpiece until the workpiece is tightly clamped to ensure the stability of the workpiece during processing.
[0027] Working principle: First, place the workpiece to be processed between multiple clamping members 19. Then, start the cylinder 15. The output end of the cylinder 15 pushes the push plate 16 to move. When the push plate 16 moves, it drives the moving seat 17 to move. The movement of the moving seat 17 drives the positioning rod 18 to move. The positioning rod 18 drives the multiple clamping members 19 to approach each other. The clamping members 19 approach the workpiece until the workpiece is tightly clamped. After the workpiece is clamped, turn off the cylinder 15 to complete the fixation of the workpiece. This realizes the convenient clamping and fixation of workpieces with different sizes, can ensure the machining accuracy, avoid machining errors caused by unstable fixation, increases the production adaptability of the machining center, enables the machine tool to meet more diverse production requirements. After clamping and fixing the workpiece, start the motor 5. The output end of the motor 5 drives the driving gear 6 to rotate. The rotation of the driving gear 6 drives the meshing-connected driven gear 7 to rotate. The driven gear 7 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the fixed seat 14 to rotate. When the fixed seat 14 rotates, it drives the rotating rod 21 to rotate synchronously. The rotation of the rotating rod 21 drives the rotating plate 9 and the connecting rod 10 to rotate. The rotation of the connecting rod 10 drives the connecting plate 11 and the limiting column 12 to rotate, causing the limiting column 12 to slide inside the limiting ring 13. Under the action of the limiting column 12, the stability of the fixed seat 14 during rotation is improved. When the fixed seat 14 rotates, it drives the workpiece inside to flip, realizing the automatic flipping of the workpiece, which can reduce manual operation, save time, accurately control the flipping position, ensure the accurate alignment of the workpiece during machining, and improve the machining accuracy.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
