Description of the Drawings

[0014] The drawings further illustrate the present utility model, but the content in the drawings does not constitute any limitation to the present utility model.

[0015] Figure 1 It is a schematic diagram of the overall structure of one embodiment of the present utility model.

[0016] Wherein: short material pressing box 1, positioning table 2, blanking guiding portion 421, wood to be processed 5, thin wall cylinder 31, pressing block 32, blanking rack 42, blanking cylinder 41, blanking guide plate 43, limiting opening 21, cylinder mounting plate 11, pipe threading rack 12. Detailed Embodiment

[0017] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.

[0018] A short material tenon processing clamping mechanism of this embodiment is referred to in the attached Figure 1, including a short stock pressing box 1, a pressing component, a positioning table 2 and a blanking component arranged on the short stock pressing box 1. The pressing component is arranged above the positioning table 2, and the blanking component is arranged below the positioning table 2. A clamping space for clamping the wood 5 to be processed is formed between the pressing end of the pressing component and the upper surface of the positioning table 2. An inclined blanking guiding part 421 is arranged at the telescopic end of the blanking component. When the blanking component extends, the blanking guiding part 421 can pass through the positioning table 2 and extend above the positioning table 2.

[0019] During processing, the feeding mechanism of the numerically controlled double-end tenoner moves the short wood to be processed onto the positioning table 2. At the same time, the pressing end of the pressing component extends so that the short wood is fixed between the pressing component and the positioning table 2, facilitating the tenon processing of the end of the wood. After waiting for the numerically controlled double-end tenoner to complete the processing of the wood, the pressing component releases the wood. At the same time, the blanking component extends so that the blanking guiding part 421 pushes the wood, and the wood after tenon processing is slid down by using the guiding of the blanking guiding part 421. The above actions are cycled to realize the automatic loading and unloading and clamping processing actions, solving the problems of difficult clamping and difficult blanking during the tenon processing of short wood by the existing numerically controlled double-end tenoner.

[0020] Preferably, the pressing component includes a thin-walled cylinder 31 and a pressing block 32. The thin-walled cylinder 31 is fixed on the top of the short stock pressing box 1. The telescopic end of the thin-walled cylinder 31 is arranged vertically downward, and the pressing block 32 is arranged at the telescopic end of the thin-walled cylinder 31. Thus, using the thin-walled cylinder 31 as the power source has the characteristics of fast response and stable output. By controlling the telescopic movement of the thin-walled cylinder 31, efficient and precise control of the pressing block 32 can be achieved. The thin-walled cylinder 31 drives the pressing block 32 to move closer to or away from the positioning table 2, realizing clamping during the processing of the wood to be processed or releasing after the processing is completed, thereby ensuring the stable clamping of the wood 5 to be processed. The pressing block 32 is designed according to the size of the short wood to meet the tenon processing requirements of the short wood.

[0021] Preferably, the blanking assembly includes a blanking frame 42 and a blanking cylinder 41. The blanking cylinder 41 is fixed on the short-material pressing box 1, and the telescopic end of the blanking cylinder 41 is vertically upward. The blanking frame 42 is arranged at the telescopic end of the blanking cylinder 41. The top edge of the blanking frame 42 is provided with an inclined downward hypotenuse along the side away from the positioning table 2, forming a blanking guiding portion 421. Thus, by setting the hypotenuse at the top edge of the blanking frame 42 to form the blanking guiding portion 421, and arranging the blanking frame 42 at the telescopic end of the blanking cylinder 41, by controlling the telescopic movement of the blanking cylinder 41, the blanking frame 42 can be located below the positioning table 2 before clamping the wood and during the processing of the clamped wood, avoiding affecting the operation of the pressing assembly. After the processing is completed and the pressing assembly releases the wood, the blanking frame 42 is driven by the action of the blanking cylinder 41 to rise through the positioning table 2, thereby jacking up the wood. Since the top of the blanking frame 42 is provided with an inclined blanking guiding portion 421, the wood slides down along the blanking guiding portion 421 to achieve automatic blanking.

[0022] Further, the blanking assembly further includes a blanking guide plate 43. The blanking guide plate 43 is inclined, and the top of the blanking guide plate 43 is connected to one side of the positioning table 2. The blanking guide plate 43 and the positioning table 2 are provided with a limiting opening 42 through which the blanking guiding portion 421 can pass. The top of the blanking guide plate 43 is connected to one side of the positioning table 2, so that when the blanking cylinder 41 drives the blanking frame 42 to rise through the positioning table 2 to jack up the wood, the wood first slides along the blanking guiding portion 421 to the blanking guide plate 43, and then slides down along the blanking guide plate 43 to a processing position away from the numerical control double-end tenoner, avoiding affecting the processing of the numerical control double-end tenoner and ensuring the safety and stability of the processing. The limiting opening 42 is opened on the blanking guide plate 43 and the positioning table 2, so that the blanking frame 42 can pass through the positioning table 2 to complete the guiding blanking action.

[0023] Preferably, the blanking assembly further includes a cylinder mounting plate 11. The cylinder mounting plate 11 is welded on the short-material pressing box 1, and the blanking cylinder 41 is fixed on the cylinder mounting plate 11. The cylinder mounting plate 11 is provided for fixing the blanking cylinder 41.

[0024] Preferably, it further includes a pipe threading frame 12. The pipe threading frame 12 is arranged above the thin-wall cylinder 31. Since the thin-wall cylinder 31 needs to be connected with an air pipe to provide the compressed air required for the telescopic movement, by arranging the pipe threading frame 12 above the thin-wall cylinder 31 for connecting the air pipe of the thin-wall cylinder 31, the effect of wire management is achieved, avoiding the connection air pipe from falling on the processing position and ensuring the safety of the processing.

[0025] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
