Description

Technical Field

[0001] This utility model relates to the field of processing tooling technology, and more specifically, it relates to a processing tooling for craniofacial bone plates. Background Technology

[0002] In existing technologies and tooling designs, the methods for fixing bone plates lack sufficient flexibility. During actual processing, the bone plates may need to be adjusted multiple times to ensure precise alignment with the processing equipment. However, existing tooling typically relies on traditional clamping or positioning devices when fixing bone plates. Once this fixing method is set, it is difficult to quickly adjust or re-fix them.

[0003] Flexible pressure blocks are typically used in the processing of craniofacial bone plates to provide appropriate pressure to ensure the stability of the bone plate during processing. However, existing tooling has significant problems in releasing the flexible pressure blocks. Current methods of releasing the blocks are usually quite complicated, requiring manual disassembly by operators or cumbersome mechanical adjustments. This not only wastes time but may also lead to operational errors or wear and tear on mechanical parts.

[0004] Similar to the unfixation process, existing tooling also has shortcomings in quickly fixing the flexible pressure block. When processing bone plates, it is necessary to quickly and stably fix the flexible pressure block in the designated position to ensure that the pressure is evenly transmitted during the processing. If the fixing process is too slow or unstable, it will affect the processing accuracy and may even cause the shape of the bone plate to be deformed or not meet the design requirements.

[0030] Please see Figures 1-5 A craniofacial bone plate processing fixture includes a fixed platform 1, on which a rotating assembly is provided. The rotating assembly includes a motor 2, an operating platform 3, a base plate 4, a cylinder 5, and a hinge rod 6. The motor 2 is fixedly mounted on the fixed platform 1. The operating platform 3 is connected to the output end of the fixed platform 1 and is rotatably connected to the fixed platform 1. The base plate 4 is set on the operating platform 3. The cylinder 5 is fixedly mounted on the base plate 4. The hinge rod 6 is connected to the output end of the cylinder 5. A pressing assembly is provided on the hinge rod 6. The pressing assembly includes a flexible pressing block 7, an abutting tube 8, and an abutting plate 9. The flexible pressing block 7 is detachably mounted on the hinge rod 6. The abutting tube 8 is slidably connected to the hinge rod 6 and the flexible pressing block 7. The abutting plate 9 is connected to one end of the abutting tube 8 and is in close contact with one end of the flexible pressing block 7.

[0031] One end of the cylinder 5 is rotatably connected to a rotating rod 10, and one end of the rotating rod 10 is rotatably connected to a hinge rod 6. A flexible placement plate 11 is placed on the base plate 4.

[0032] The flexible placement plate 11 has a placement groove 12, and a plate 13 is placed on the placement groove 12. The plate 13 is in close contact with the flexible pressing block 7.

[0033] A sleeve 14 is slidably connected to the abutting tube 8. One end of the sleeve 14 is tightly attached to one end of the flexible pressing block 7. A moving rod 15 is slidably connected to the sleeve 14.

[0034] A rotating plate 16 is rotatably connected to the moving rod 15, and an adjusting rod 17 is connected to the rotating plate 16.

[0035] The sleeve 14 is provided with an unlocking groove 18, which is adapted to the adjusting rod 17.

[0036] In this embodiment, during use, the motor 2 is started, causing the operating table 3 at the output end to rotate along the fixed platform 1. During this rotation, the plate 13 in the placement groove 12 on the flexible placement plate 11 placed on the base plate 4 is adjusted in angle. After adjusting to a suitable angle, it is processed. After the plate 13 is placed in the placement groove 12 of the flexible placement plate 11, the cylinder 5 is started, causing the hinge rod 6 at the output end to rotate. During this rotation, the hinge rod 6 rotates along the rotating rod 10 at one end, and the rotating rod 10 rotates along one end of the cylinder 5. This allows the flexible pressing block 7 fixed on the hinge rod 6 to fix the plate 13. When the flexible pressing block 7 needs to be replaced after a period of use, the rotating plate 16 rotates along the moving rod 15. During this rotation, the adjusting rod 17 is rotated to the unlocking groove 18 of the sleeve 14, thus releasing the fixing of the adjusting rod 17.

[0037] Please see Figure 4-5 As an embodiment of a craniofacial bone plate processing fixture for locking components: a locking component is provided on the sleeve 14. The locking component includes a moving groove 19, a ball 20 and a spring 21. The moving groove 19 is opened on the moving rod 15. The ball 20 is rotatably connected to the sleeve 14. The spring 21 is connected between the moving rod 15 and the sleeve 14.

[0038] Both the abutment tube 8 and the sleeve tube 14 are provided with slots 22, and the placement slot 12 is adapted to the ball 20.

[0039] More specifically, after releasing the fixing process of the moving rod 15, the moving rod 15 is slidably moved along the sleeve 14. As it continues to slide, the spring 21 between the moving rod 15 and the sleeve 14 is compressed by one end of the moving rod 15. During the movement of the moving rod 15, the moving groove 19 on the moving rod 15 is moved. After the moving groove 19 on the moving rod 15 is moved to be aligned with the slot 22 on the abutting tube 8 and the sleeve 14, the ball 20 rolls from the slot 22 to the moving groove 19 of the moving rod 15, thereby releasing the fixing process of the abutting tube 8. At this time, the abutting tube 8 is slid out along the hinge rod 6 and the flexible pressing block 7, and the moving rod 15 and the sleeve 14 are slid out along the flexible pressing block 7, thereby releasing the fixing process of the flexible pressing block 7. At this time, the replacement process of the flexible pressing block 7 is completed.

[0040] In summary, during the use or operation of the overall equipment: During use, the motor 2 is started, causing the operating table 3 at the output end to rotate along the fixed platform 1. During this rotation, the plate 13 in the placement groove 12 on the flexible placement plate 11 placed on the base plate 4 is adjusted in angle. After adjusting to a suitable angle, it is processed. After placing the plate 13 in the placement groove 12 of the flexible placement plate 11, the cylinder 5 is started, causing the hinge rod 6 at the output end to rotate. During this rotation, the hinge rod 6 rotates along one end of the rotating rod 10, and the rotating rod 10 rotates along one end of the cylinder 5. This allows the flexible pressing block 7 fixed on the hinge rod 6 to fix the plate 13. When the flexible pressing block 7 needs to be replaced after a period of use, the rotating plate 16 rotates along the moving rod 15. During this rotation, the adjusting rod 17 is moved to the unlocking groove 18 of the sleeve 14, releasing the fixing of the adjusting rod 17.

[0041] After releasing the fixing process of the moving rod 15, the moving rod 15 is slidably moved along the sleeve 14. As it continues to slide, the spring 21 between the moving rod 15 and the sleeve 14 is compressed by one end of the moving rod 15. During the movement of the moving rod 15, the moving groove 19 on the moving rod 15 is moved. After the moving groove 19 on the moving rod 15 is moved to align with the slot 22 on the abutting tube 8 and the sleeve 14, the ball 20 rolls from the slot 22 to the moving groove 19 on the moving rod 15, thereby releasing the fixing process of the abutting tube 8. At this time, the abutting tube 8 is slid out along the hinge rod 6 and the flexible pressing block 7, and the moving rod 15 and the sleeve 14 are slid out along the flexible pressing block 7, thereby releasing the fixing process of the flexible pressing block 7. This completes the replacement process of the flexible pressing block 7.

For all the fixed connections mentioned above, welding is preferred.
