[0031] In the specific implementation process, a large amount of wood chips and dust will be generated during the working process of the face milling machine, if the motor 16 is directly exposed, these wood chips and dust are easy to enter the inside of the motor 16, which will interfere with the normal operation of the motor 16, and even damage the parts of the motor 16, by installing the motor 16 in the motor box 17, the wood chips and dust can be effectively isolated, and the internal structure of the motor 16 is protected from damage.
[0032] Referring to Figure 4 , a fixture of a face milling machine, the top end of the hydraulic rod 20 is connected with the processing platform 13.
[0033] In the specific implementation process, the base of the hydraulic rod 20 is accurately and stably installed on the table 1, and the top end of the hydraulic rod 20 is connected with the processing platform 13 through a flange, ensuring firm and reliable connection, so that the processing platform 13 can be stably lifted with the extension and retraction of the hydraulic rod 20, and will not be subjected to excessive lateral force or torsional force.
[0034] Referring to Figure 3As shown in the figure, a fixture of a face milling machine, the top end of the inner arc wall of the circular groove 22 is provided with a limiting ring, which can limit the vertical upward movement of the processing platform 13.
[0035] In the implementation process, the main function of the limiting ring is to limit the maximum vertical upward movement of the processing platform 13, so as to ensure the stability and safety of the fixture during processing. When the processing platform 13 rises to a predetermined height, the limiting ring will prevent it from continuing to rise, preventing accidents from occurring.
[0036] Referring to Figure 1 As shown in the figure, a fixture of a face milling machine, the three sides of the clamping plate 12 close to each other are provided with rubber sleeves, and the clamping plate 12 is arc-shaped, with the concave part of the arc-shaped part facing the spherical wood element 8.
[0037] In the implementation process, the main function of the rubber sleeve is to protect the surface of the spherical wood element 8 from being directly damaged by the clamping plate 12 and to provide better clamping friction. The concave part of the clamping plate 12 is arc-shaped, which can match the curvature of the spherical wood element 8 during clamping, so as to tightly fit and firmly clamp.
[0038] Referring to Figure 2 As shown in the figure, a fixture of a face milling machine, the collecting bin 4 is detachably mounted on the table top 1 by bolts, and the filter plate 5 is provided with a filter screen.
[0039] In the implementation process, the collecting bin 4 is detachably mounted on the table top 1 by bolts, which facilitates cleaning, maintenance and replacement when needed. When the fine wood chips and waste in the collecting bin 4 accumulate to a certain extent, it can be easily removed and emptied, while larger wood chips are blocked on the other side of the filter plate 5 relative to the collecting bin 4, so as to enter the discharge chute 6 and be collected by the operator.
[0040] Working principle:
[0041] Step 1: When the spherical wood element 8 needs to be processed, first start the motor 16. The motor 16 drives one of the rotating shafts 19 to rotate through the transmission shaft, and the rotating shaft 19 drives the bevel gear 18 to rotate. Since the bevel gear 18 is meshed and connected with the tooth ring 14, the tooth ring 14 will also rotate. The wire coil 15 above the tooth ring 14 is meshed with the screw thread on the bottom surface of the sliding block 9. With the rotation of the tooth ring 14, the wire coil 15 drives the sliding block 9 to move horizontally in the square groove 21 of the top plate 7 through the meshing action of the screw thread. The movement of the sliding block 9 drives the connecting block 11 and the clamping plate 12 to move towards the spherical wood element 8. Since the clamping plate 12 is arc-shaped and its concave part faces the spherical wood element 8, the clamping plate 12 can tightly fit and firmly clamp the spherical wood element 8. The limiting block 10 on the sliding block 9 ensures that the sliding block 9 remains straight and stable during movement, avoiding deviation or shaking.
[0042] Step two: the processing platform 13 is connected with the structure in the circular groove 22 through the gear ring 14. If it is necessary to adjust the height of the processing platform 13 during the processing, the hydraulic rod 20 can be started. The extension and retraction of the hydraulic rod 20 drives the processing platform 13 to move up and down. When the processing platform 13 rises to the predetermined height, the limiting ring at the top end of the arc wall in the circular groove 22 will prevent it from continuing to rise, ensuring the stability and safety during the processing.
[0043] Step three: during the processing, the impeller 3 generates airflow to help remove the wood chips or dust generated during the processing, keeping the working environment clean. The wood chips or dust blown by the impeller 3 are collected by the collection bin 4. The filter plate 5 is installed on the side close to the shell 2. The filter screen on the filter plate 5 can block large particles from entering the inside of the collection bin 4, while allowing air to pass through. The discharge slot 6 opened below the filter plate 5 facilitates the cleaning of the collected wood chips. When the wood chips in the collection bin 4 accumulate to a certain extent, they can be removed and emptied.
