[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The mortising machine will produce a lot of sawdust and dust during the wood processing process. This dust not only affects the working environment, but also may cause harm to the health of the operators.

[0027] See also Figures 1-6As shown, this embodiment provides a CNC double-end tenoning machine, including a base 1. In order to collect debris, the specific details are as follows: the base 1 is fixedly connected to side panels 23 on both sides near the middle end, and a hole groove 232 is provided on the outer surface of the side panel 23 near the front. A T-shaped groove 231 is provided on the top of the side panel 23, and the top of the base 1 is fixedly connected to a shell 21 on both sides. The inner surface of the back of the shell 21 is fixedly connected to the outer surface of the side panel 23, and an L-shaped groove 211 is provided on the upper surface of the shell 21. A sliding plate 212 is slidably connected inside the L-shaped groove 211. The lower end of the inner surface of the sliding plate 212 is fixedly connected to a pressing plate 2, and the bottom of the pressing plate 2 is fixedly connected to a rack 252. The inner surface of the rack 252 slides The gear 251 is fixedly connected to the outer surface of the middle end of the rotating shaft 25, and the outer surface of the gear 251 is meshed with the outer surface of the rack 252. The rack 252 is driven up and down by the rotation of the gear 251, and the pressure plate 2 is driven up and down by the up and down movement of the rack 252. The sliding plate 212 is driven to slide on the inner wall of the L-shaped groove 211 by the up and down movement of the pressure plate 2. However, the existing tenoning machine does not block the debris, resulting in the debris generated during the operation of the tenoning machine flying everywhere. The debris splashing area is large and not easy to clean, and it is easy to splash into the eyes of the staff, causing eye injury or even blindness, and the safety is limited.

[0028] The improvement of this embodiment is that:

[0029] The motor 255 rotates to drive the worm 254 to rotate. The worm 254 rotates, and the left and right sides of the worm 254 have opposite directions of threads, which drives the worm wheel 253 to rotate. The rotation of the worm wheel 253 drives the rotating shaft 25 to rotate. The rotation of the rotating shaft 25 drives the gear 251 to rotate. The rotation of the gear 251 drives the rack 252 to move up and down. The up and down movement of the rack 252 drives the pressure plate 2 and the sliding plate 212 to move up and down, so that the conveying mechanism sends the plate over. The shell 21 does not affect the entry of the plate, and can also block debris during processing, thereby improving safety.

[0030] In order to allow the rotating shafts 25 on both sides to rotate simultaneously, a worm gear 253 is fixedly connected to the other end of the rotating shaft 25, and the outer surface of the worm gear 253 is meshed with a worm 254. The outer surface of the worm 254 rotates inside the side plate 23, and the opposite thread lines on the surface of the worm 254 drive the worm gears 253 on both sides to rotate. The rotation of the worm gears 253 on both sides drives the rotating shaft 25 to rotate, so that the rotating shafts 25 on both sides can rotate simultaneously.

[0031] In order to facilitate the rotation of the worm 254, the end of the worm 254 is fixedly connected to the end of the motor 255, and the other end of the motor 255 is fixedly connected to the support plate 24. The front side of the support plate 24 is fixedly connected to the outer surface of the rear side of the shell 21. The rotation of the motor 255 drives the worm 254 to rotate, thereby realizing the convenience of rotating the worm 254 and improving the degree of automation.

[0032] In order to facilitate the cleaning of dust in the shell 21, a rotating plate 22 is connected to the front of the shell 21 through rotation. A circular groove 221 is provided on the inner surface of the rotating plate 22. The rotating plate 22 rotates to facilitate the cleaning of dust in the shell 21.

[0033] In order to prevent the rotating plate 22 from rotating at will, a cylindrical block 3 is slidably connected to the inner wall of the circular groove 221, a T-shaped block 32 is fixedly connected to the axis of the cylindrical block 3, the outer side of the end of the cylindrical block 3 is fixedly connected to the end of a spring 31, and the other end of the spring 31 is fixedly connected to the inner side of the inner surface of the hole groove 232. The cylindrical block 3 is driven to move left and right by the expansion and contraction of the spring 31, and the T-shaped block 32 and the spring 31 are fixed by the side plate 23. The cylindrical block 3 is fixed by the T-shaped block 32 and the spring 31, so that the rotating plate 22 does not rotate at will.

[0034] In summary, the working principle of this solution is as follows:

[0035] Connect the motor 255 to the power supply, and the motor 255 rotates to drive the worm 254 to rotate. The worm 254 rotates and the threads on the left and right sides of the worm 254 are in opposite directions, which drives the worm wheel 253 to rotate in the same direction. The rotation of the worm wheel 253 drives the shaft 25 to rotate. The rotation of the shaft 25 drives the gear 251 to rotate. The rotation of the gear 251 drives the rack 252 to move up and down. The up and down movement of the rack 252 drives the pressing plate 2 and the sliding plate 212 to move up and down. When processing is required, the motor 255 rotates The worm 254 is driven to rotate, and the worm wheel 253 is driven to rotate in the same direction by the rotation of the worm 254. The rotation of the worm wheel 253 drives the rotating shaft 25 to rotate, and the rotation of the rotating shaft 25 drives the gear 251 to rotate. The rotation of the gear 251 drives the rack 252 to move upward, and the upward movement of the rack 252 drives the pressure plate 2 and the sliding plate 212 to move upward, and the plate is sent to the side plate 23 through the transmission mechanism. The rotation of the motor 255 drives the worm 254 to rotate, and the rotation of the worm 254 drives the worm wheel 253 to rotate. The worm gear 253 rotates to drive the shaft 25 to rotate, and the shaft 25 rotates to drive the gear 251 to rotate, and the gear 251 rotates to drive the rack 252 to move downward, and the rack 252 moves downward to drive the pressing plate 2 and the sliding plate 212 to move downward. The bottom of the template is pressed on the concave part of the side plate 23, and the bottom of the pressing plate 2 is pressed on the wooden board. The pressing plate 2 brings the sliding plate 212 down to cover the wooden board. When there are many debris at the bottom, manually pull the T-shaped block 32, and the column block 3 is driven to move by the T-shaped block 32. 3 drives the spring 31 to retract, manually pull the rotating plate 22 outward, sweep it out with a broom, close the rotating plate 22, manually pull the T-shaped block 32, and drive the column block 3 to move through the T-shaped block 32, and drive the spring 31 to retract through the column block 3. When the rotating plate 22 is perpendicular to the side plate 23, release your hand, and the spring 31 rebounds and drives the column block 3 to move and insert into the circular groove 221. The column block 3 will not slide out due to mechanical vibration, which has the effect of reducing dust and preventing flying chips, and the flying chips are easy to clean, which increases safety and practicality.
