Technical Field

[0001] This utility model is a rotatable clamping mechanism for round logs, belonging to the field of wood processing machinery and equipment. Background Technology

[0002] In the process of continuous development of modern society, wood is involved in all aspects of life. When logging and processing wood, log clamping devices are generally used to clamp and fix the logs, which facilitates processing. However, traditional log clamping devices require manual adjustment of the clamping structure to accommodate different logs. At the same time, the force of traditional log clamping devices cannot be well controlled, which can easily damage the wood and reduce the quality of raw materials. Therefore, it is necessary to improve them.

[0003] Existing clamping mechanisms require rotating the clamped logs to facilitate processing on different surfaces. They also require loosening the logs and then clamping them again, which is time-consuming, labor-intensive, and prolongs the operation time. Utility Model Content

The sleeve 18 is rotatably connected between the rotary connecting plate 16 and the rotary connecting plate 23. The rotary clamping assembly also includes a rectangular through slot inside the sleeve 18. A rotary clamping plate 14 is slidably connected within the rectangular through slot. One end of the rotary clamping plate 14 is connected to the rotary fixed axis 1. One end of 5 is rotatably connected, and the other end of the rotating fixed shaft 15 is fixedly connected to one side surface of the clamping plate 2. The other end of the rotating clamping plate 14 is pin-connected to the roller 19. The rotating clamping assembly also includes a tension plate 13 with one end fixedly connected to the outer circumference of the clamping plate 2. The other end of the tension plate 13 is pin-connected to one end of the telescopic rod connecting plate 12. The other end of the telescopic rod connecting plate 12 is fixedly connected to one end of the telescopic rod 11. The other end of the telescopic rod 11 is connected to the extension shaft end of the telescopic motor 7. One side surface of the telescopic motor 7 is fixedly connected to one end of the telescopic motor connecting plate 8. The other end of the telescopic motor connecting plate 8 is pin-connected to one side surface of the clamping plate 2.

[0029] See Figure 4 , Figure 5 , Figure 6 and Figure 7The clamping assembly includes a telescopic motor plate 5 fixedly connected to the upper surface of the base plate 1. A telescopic motor 6 is fixedly connected to one side surface of the telescopic motor plate 5. The extension shaft end of the telescopic motor 6 is connected to one end of a telescopic rod 36. The other end of the telescopic rod passes through the cross clamping guide plate 24 and into the cross guide groove 26, where it is fixedly connected to one side surface of the cross connecting plate 34. A guide inclined plate 35 is fixedly connected to each of the four end faces of the cross connecting plate 34. The guide inclined plate 35 is slidably connected in the guide inclined groove 32, which is formed on one side surface of the guide plate 30. The clamping assembly also includes two sliding plates 31 fixedly connected to the two sides of the guide plate 30. The guide plate 30 and the sliding plates 31 are slidably connected in the cross guide groove 26 and the cross sliding groove 33, respectively. Both the cross slide groove 33 and the cross clamping guide plate 24 are provided. The cross guide groove 26 is connected to the cross slide groove 33. One side of the guide plate 30 passes through the cross guide groove 26 and is fixedly connected to one end of the arc clamping plate 25. The other end of the arc clamping plate 25 passes through the rotating groove 27 and into the clamping groove 10. The snap-fit ​​plate 24 is provided with a rotating limiting groove 28. One end of the rotating limiting plate 29 is rotatably connected in the rotating limiting groove 28. The other end of the rotating limiting plate 29 passes through the rotating limiting groove 28 and is fixedly connected to one side surface of the cross clamping guide plate 24. The rotating connecting plate 16 is provided with a docking groove 21. The docking groove 21 is rotatably connected to the snap-fit ​​groove 20. The rotating connecting plate 23 and the rotating connecting plate 16 are both provided with circular through grooves. The circular through grooves are connected to the round wooden through groove 9.

[0030] In use, when the log body passes through the circular through groove and the log through groove 9 into the clamping groove 10, the telescopic motor 7 is started, causing the telescopic rod 11 to push the tension plate 13 to rotate through the pin shaft. Then, the tension plate 13 drives the rotating connecting plate 16 to rotate. At the same time, due to the auxiliary limiting between the docking groove 21 and the locking groove 20 of the rotating connecting plate 16, the rotating connecting plate 16 will not be misaligned when it rotates. When the rotating connecting plate 16 rotates, it drives the rotating connecting plate 23 to rotate simultaneously through the three connecting columns 22. Then, the rotating connecting plate 23 drives the sleeve 18 to rotate through the three sleeve shafts 17. Then, the sleeve 18 drives the rotating clamping plate 14 to rotate inward around the rotating fixed shaft 15 as the axis. At this time, the three rotating clamping plates 14 rotate and clamp the log body through the rollers at one end.

[0031] When a secondary clamping operation is required on the log body, the telescopic motor 6 is activated, causing the telescopic rod 36 to pull the cross connecting plate 34 outward. Through the limiting between the guide inclined plate 35 and the guide inclined groove 32 on the four sides of the cross connecting plate 34, the cross connecting plate 34 moves while the guide inclined plate 35 pulls the four guide plates 30 in the same direction. Because the cross guide groove 26 and the cross slide groove 33 provide auxiliary limiting between the guide plate 30 and the slide plate 31, the four guide plates 30 move smoothly under the limiting pulling force between the guide inclined plate 35 and the guide inclined groove 32. Then, the guide plates 30 drive the arc clamping plate 25 to move in the same direction at the same time. Thus, the four arc clamping plates 25 perform a secondary clamping operation on the log body. Under the auxiliary limiting between the rotating limiting plate 29 and the rotating limiting groove 28, the secondary clamped log body can be rotated to meet the processing of different outer surfaces of the log body.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
