[0036] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the punching mechanism 6 includes a first mounting frame 61, a servo motor 62, a rubber block 63, a nut 64, a mounting sleeve 65, a fixing piece 66, a first spring 67, a clamping sleeve 68, a limiting ring 69 and a punching head 610. The rear side of the mounting seat 1 is connected to the first mounting frame 61, the servo motor 62 is slidably connected to the first mounting frame 61, the front part of the servo motor 62 is connected to the rubber block 63, the rubber block 63 is in contact with the first mounting frame 61, the front side of the servo motor 62 is threadedly connected to the nut 64, and the servo motor A mounting sleeve 65 is connected to the output shaft of the machine 62, and a fixing piece 66 is slidably connected to the front and rear parts of the mounting sleeve 65, and three first springs 67 are connected between the fixing piece 66 and the mounting sleeve 65. A clamping sleeve 68 is rotatably connected to the mounting sleeve 65, and the clamping sleeve 68 is pressed and fitted with the fixing piece 66. A limiting ring 69 is connected to the bottom of the mounting sleeve 65, and the limiting ring 69 is clamped with the clamping sleeve 68. A punching head 610 is clamped inside the mounting sleeve 65, and the punching head 610 is pressed and fitted with the fixing piece 66.

[0037] like Figure 1 and Figure 8 As shown, the fixing mechanism 7 includes a slide plate 71, a sliding member 72, a first clamping plate 73 and an adjusting rod 74. The slide plate 71 is connected to the top of the mounting seat 1. The left and right parts of the slide plate 71 are slidably connected to the sliding member 72. The upper part of the sliding member 72 is slidably connected to the first clamping plate 73. The rear part of the sliding member 72 is rotatably connected to the adjusting rod 74. The adjusting rod 74 is threadedly connected to the adjacent first clamping plate 73.

[0038] When the present invention is used, the mounting seat 1 is first placed in the bamboo furniture processing area, and then the bamboo furniture production board is placed on the sliding member 72. By rotating the adjusting rod 74, the first clamping plate 73 is moved downward to the sliding member 72 under the action of the thread to clamp the bamboo furniture production board, and then the sliding member 72 is slid on the slide plate 71 to adjust the position of the bamboo furniture production board. After the position of the bamboo furniture production board is adjusted, the punching head 610 is inserted into the installation sleeve 65 for clamping, and the fixing member 66 is pressed close to each other by rotating the pressing sleeve 68. The first spring 67 is compressed to fix the punching head 610, so that when the output shaft of the servo motor 62 drives the mounting sleeve 65 to rotate, the mounting sleeve 65 can drive the punching head 610 to rotate at a high speed to punch and cut the bamboo furniture production board. At the same time, the servo motor 62 can slide on the first mounting frame 61 to adjust the cutting angle, and the rubber block 63 is squeezed by the nut 64 so that the rubber block 63 is deformed to fix the servo motor 62 or increase the resistance of the servo motor 62 when it moves, thereby improving the stability of the servo motor 62 when it moves. The punching head 610 needs to be adjusted according to the cutting requirements. When replacing, the pressing sleeve 68 is rotated, and the pressing sleeve 68 no longer squeezes the fixing member 66, so that the first spring 67 rebounds, and the fixing member 66 is reset and separated from the punching head 610. Then the punching head 610 is pulled out and replaced. The replaced punching head 610 repeats the above-mentioned operation of engaging with the installation sleeve 65 to fix the punching head 610. After the punching head 610 is installed, the sliding block 2 is moved by rotating the adjusting screw rod 5, and the folding connecting member 3 is controlled to lift the lifting plate 4 upward, so that the bamboo furniture production board moves upward and contacts with the punching head 610 for cutting. Cutting operation, after cutting is completed, rotate the adjusting screw rod 5 in the opposite direction, so that the folding connecting part 3 controls the lifting plate 4 to reset downward, and then control the first clamping plate 73 to reset upward through the adjusting rod 74, and take out the bamboo furniture production board. By adjusting the position of the servo motor 62 as mentioned above, the bamboo furniture production board is fixed by the first clamping plate 73 and the sliding part 72, and the auxiliary adjusting screw rod 5 controls the sliding block 2 to adjust the folding connecting part 3 to lift the lifting plate 4 upward, so as to achieve the effect of moving the board to contact with the cutting part, and there is no need to manipulate the cutting part to improve the cutting accuracy and convenience of cutting operation.

[0039] like Figure 1 and Fig. 9 As shown, it also includes a positioning mechanism 8, which includes a second mounting frame 81, an alignment rod 82 and a second spring 83. The second mounting frame 81 is connected to the bottom of the servo motor 62, and the lower sides of the left and right parts of the second mounting frame 81 are both slidably connected to the alignment rod 82, and the upper sides of the front and rear parts of the alignment rod 82 are connected to the second mounting frame 81 with a second spring 83.

[0040] The use of the alignment mechanism 8 of the present invention can assist the punching head 610 in alignment cutting. When the punching head 610 is cutting, the alignment rod 82 contacts the bamboo furniture production board to mark the position of the punching head 610, which is convenient for calibrating the position of the punching head 610. When the alignment rod 82 contacts the bamboo furniture production board, it will slide upward to compress the second spring 83. When the alignment rod 82 is separated from the bamboo furniture production board, the second spring 83 rebounds to automatically reset the alignment rod 82. Through the above-mentioned operation of the alignment rod 82 contacting the bamboo furniture production board and marking the position of the punching head 610, it is possible to achieve the effect of facilitating the calibration of the position of the punching head 610 and improving the alignment accuracy of the punching head 610.

The servo motor 62 slides on the first mounting frame 61 to drive the adjusting block 93 to rotate through the swing rod 96, so that the adjusting block 93 is always on the same horizontal plane as the punching head 610. At the same time, the limiting plate 92 can limit the rising height of the lifting plate 4, and cooperate with the adjusting block 93 to control the cutting depth of the punching head 610. The limiting plate 92 can slide on the guide frame 91, and the swing rod 96 can also slide on the adjusting block 93. The adjustment block 93 is enabled to adapt to the punching heads 610 of different lengths and to limit the cutting depths of the punching heads 610 of different lengths. After the sliding adjustment of the adjustment block 93 is completed, the second clamping plate 94 is controlled to approach each other by tightening the screw rod 95 to clamp the swing rod 96. The above-mentioned limit plate 92 and the adjustment block 93 are moved up and down for adjustment to adapt to the specifications and cutting depth of the punching head 610. The operation of limiting the punching head 610 and the lifting plate 4 can achieve the effect of limiting the lifting plate 4 and the cutting depth and improving the cutting accuracy.
