Technical Field

[0001] The utility model relates to the field of woodworking cutting, in particular to an auxiliary device for cutting circular plates on a vertical band sawing machine. Background Technique

[0002] Wood boards are a common building material and also the main component of wooden furniture. Currently, some furniture is provided with circular wood boards, and the circular boards are cut from rectangular or square wood boards.

[0003] When the applicant applied for the present utility model, after retrieval, it was found that the Chinese patent disclosed "an auxiliary device for cutting circular plates on a vertical band sawing machine", and its application number was "CN202420078186.1". When this patent is used, first, holes are drilled in the wood board to be cut to facilitate the positioning post 7 to be inserted into the wood board, and then the position of the adjusting block 4 is adjusted to make the outer edge of the template 6 tangent to the cutting groove 11. Then, the wood board to be cut is inserted between the reference plate 1 and the cantilever 41, the positioning post 7 is inserted into the wood board, and then the auxiliary device is inserted into the vertical band sawing machine. The positioning guide bar 2 is inserted into the corresponding limit groove provided on the vertical band sawing machine, which can limit the longitudinal movement of the reference plate 1; and the band saw of the vertical band sawing machine is inserted into the cutting groove 11 of the reference plate 1.

[0029] Place the rectangular or square wooden board to be cut on the turntable 2. Then, adjust the operation of the motor 6 to drive the adjusting screw 7 to rotate, causing the two moving plates 4 to move relative to each other. The two moving plates 4 and the U-shaped plates 8 connected to their bottoms move together relatively, causing the tops of the two connecting rods 9 to move with the two U-shaped plates 8 respectively. The bottoms of the two connecting rods 9 act together to push the lifting plate 10 downward. The rotating motor 12 connected to the top of the lifting plate 10 and the pressing disc 13 connected to its output end move downward together, so that the bottom of the pressing disc 13 presses the wooden board to be cut tightly on the turntable 2. The pressing disc 13 and the turntable 2 clamp the wooden board to be cut together, without the need to drill holes in the wooden board to be cut, maintaining the integrity and beauty of the wooden board. After the clamping is completed, the rotating motor 12 drives the pressing disc 13 to rotate, and then the wooden board and the turntable 2 rotate together.

Then, the rectangular or square wooden board to be cut is placed on the turntable 2. Subsequently, the motor 6 is adjusted to operate, driving the adjusting screw 7 to rotate, causing the two moving plates 4 to move relative to each other. The two moving plates 4 and the U-shaped plates 8 connected to their bottoms move relative to each other together, causing the tops of the two connecting rods 9 to move along with the two U-shaped plates 8 respectively. The bottoms of the two connecting rods 9 jointly act to push the lifting plate 10 downward. The rotating motor 12 connected to the top of the lifting plate 10 and the pressing plate 13 connected to its output end move downward together, so that the bottom of the pressing plate 13 presses the wooden board to be cut tightly on the turntable 2. The pressing plate 13 and the turntable 2 jointly clamp the wooden board to be cut. The handle 20 is rotated to drive the sliding screw rod 19 to rotate, and the slider 16 threadedly connected to the sliding screw rod 19 and the gantry 1 connected to its top move towards the band saw slot 24 until the edge of the turntable 2 is tangent to the band saw in the band saw slot 24. The rotating motor 12 drives the pressing plate 13 to rotate, thereby causing the wooden board and the turntable 2 to rotate together, and the band saw cuts along the edge of the wooden board to be processed, cutting the wooden board into a circular shape.
