[0002] In wood processing, operations such as debarking and slicing of round wood are required. At this time, the round wood needs to be stably fixed for processing operations. Since the outside of the round wood is not a plane, multi-point clamping is required to achieve fixation.

[0003] For example, the patent with the application number "CN2022214514015" discloses a fixing tooling for round wood processing, including a support base. One end of the top of the support base is provided with a first fixing column. A first shaft rod is inserted through the middle of the first fixing column. A lower cage gear is arranged at the top of the first shaft rod. A support rotating shaft is arranged at the center of the top of the lower cage gear. An upper cage gear is arranged at the top of the support rotating shaft. A second shaft rod is arranged at the center of the top of the upper cage gear. An adjusting handle is arranged at the top of the second shaft rod. A support column is arranged on the top of the support base near the first fixing column. A third fixing column is arranged at the top of the support column. A connecting rotating shaft is inserted through the middle of the third fixing column. A rotating disc is arranged at one end of the connecting rotating shaft close to the support rotating shaft. A plurality of protruding gear teeth are arranged on the side edge of the rotating disc far from the connecting rotating shaft. A first side plate is arranged at the other end of the connecting rotating shaft. The round wood to be processed is placed in the support groove protruding from the right side of the round wood support table. After several limiting clamping plates on the side move it towards the middle, the middle cylinder is clamped and fixed, thereby improving the stability during the round wood processing. In addition, when it is necessary to turn over the round wood for processing, the cage gear on one side is adjusted to rotate, and the rotating disc is driven by the rotation of the two cage gears, so as to turn over the entire clamping and fixing device.

[0047] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0048] Refer to Figures 1-11 , a fixing tool for log processing, including clamping claws that can be used individually or in two corresponding pairs.

[0049] Among them, the clamping claw includes: a plurality of force transmission rods 2 rotatably arranged on the main ring 1; a front clamping arm 3 hinged to the front end of the force transmission rod 2; a rear top plate 4 slidably arranged at the rear end of the force transmission rod 2.

[0050] As Figures 1-3 shown; when in use, after the log passes through the main ring 1 from the front side, it touches the rear top plate 4 and pushes the rear top plate 4 backward; as the rear top plate 4 moves, the connection position between it and the force transmission rod 2 changes, and the front end of the force transmission rod 2 presses downward, driving the front clamping arm 3 to hold the log, realizing fast and adaptive fixing of the log.

[0051] When a single clamping claw is used, after holding one end of the log, the other end is placed on the support surface or fixed by other components to adapt to some processing operations; when two clamping claws are used, the clamping claws on both sides approach relatively, clamp the log therein, and hold both ends to realize the fixing of the log.

[0052] It should be noted that this clamping claw can be used in combination with a variety of components.

[0053] Preferably, an extension rod 8 is provided at the rear end of the main ring 1; a flange 81 is provided at the rear end of the extension rod 8 for easy docking and installation.

[0054] As Figures 9-11 shown; the flange 81 is detachably connected to the moving base 9, and the whole is driven to move by the moving base 9 to fix the log; similarly, the flange 81 can be connected to mechanisms such as a robotic arm, a telescopic rod, and a drive shaft for cooperative use.

[0055] In some embodiments, a plurality of first clamping plates 11 are provided on the outer ring side of the main ring 1. The force transmission rod 2 is perforated and a pin shaft 5 is passed through it to be connected to the first clamping plate 11.

[0056] Preferably, the perforation of the force transmission rod 2 is arranged near the front end; as in Figure 2 wherein, the front extending part of the force transmission rod 2 is shorter and the rear part is longer.

[0057] Meanwhile, a first sliding groove 21 is provided at the rear end of the force transmission rod 2; a plurality of second clamping plates 41 are provided on the outer ring side of the rear top plate 4, and a pin shaft 5 is passed through the second clamping plate 41 and placed in the first sliding groove 21 to slide.

[0058] Thus, through the movement of the rear top plate 4, the pin shaft 5 in the second clamping plate 41 drives the rear end of the force transmission rod 2 to swing; cooperating with the front clamping arm 3, the holding and fixing of round logs with different diameters are realized.

[0059] In some embodiments, a plurality of turns of nail spikes 42 are provided around the front end of the rear top plate 4.

[0060] As Figure 8 shown, the large shaking at the tail end of the round log can be avoided.

[0061] In some embodiments, a pressing plate 6 is rotatably provided at the front end of the front clamping arm 3, and a spike 61 is provided at the lower end of the pressing plate 6 to hold the round log more stably and reliably.

[0062] Furthermore, a diagonal brace 7 is provided between the front clamping arm 3 and the force transmission rod 2 to improve the overall strength and reliability.

[0063] Among them, one end of the diagonal brace 7 is hinged to the front clamping arm 3, and a second sliding groove 71 is provided at the other end; a screw rod 72 that is fixed to the force transmission rod 2 and is inserted into the force transmission rod 2 is sleeved with a locking nut 73 on the screw rod 72.

[0064] As Figure 4 shown, after the rear top plate 4 moves backward, the holding radius at the front end becomes smaller.

[0065] As Figure 5 shown, after the diagonal brace 7 is adjusted, the holding radius at the front end becomes larger.

[0066] Thus, through the cooperation of the diagonal brace 7, the overall has a larger adaptation range.

[0067] It should be noted that usually, the diagonal brace 7 is fixed at one position; only by moving and adjusting the rear top plate 4, the fixing operation of the vast majority of round logs can be satisfied.

[0068] When the utility model is used, the log moves backward against the rear top plate 4, and the rear end of the force transmission rod 2 swings upward, so that the front clamp arm 3 at the front end moves inward to clamp and hold the log; the whole process does not require other actions, and the fixing operation can be achieved by placing and moving the log; and the structure is simple and the application range is wide. In addition, when the application range needs to be further expanded, the angle between the front clamp arm 3 and the force transmission rod 2 is changed by adjusting the diagonal support rod 7, which has a wider adaptation range.

[0069] In the utility model, the overall structure is simple and reliable, easy to maintain and low in cost; and there is no need to set up additional power. Through the cooperation of the force transmission rod 2, the front clamping arm 3 and the rear top plate 4, the front clamping arm 3 at the front end is driven by the top pressure of the log to hold the log, thereby realizing rapid and adaptive fixation of the log; it can be used in conjunction with a variety of components and has a wider range of applications; the front end of the rear top plate 4 is surrounded by spikes 42, which can avoid large shaking of the tail end of the log and make the clamping more stable; through the cooperation of the diagonal support rod 7, the whole has a larger adaptation range.
