[0025] To better understand the purpose, structure, and function of this utility model, the tool changing mechanism of a five-axis CNC machining center of this utility model will be described in further detail below with reference to the accompanying drawings.
[0026] like Figure 1-4 As shown, the tool changing mechanism of a five-axis CNC machining center of this utility model includes a conversion device 1. One end of the conversion device 1 is connected to a mounting strip 3. An anti-wear ring 14 is sleeved inside the mounting strip 3. A groove 13 is formed inside the mounting strip 3, and a sliding groove 19 is formed at the top of the mounting strip 3. By installing the anti-wear ring 14, the anti-wear ring 14 replaces the direct contact between the mounting strip 3 and the tool head 4. At this time, the wear point will appear on the surface of the anti-wear ring 14. When the anti-wear ring 14 is worn, it can be directly replaced. It is very convenient to use. A plate 15 is welded to the surface of the anti-wear ring 14. The plate 15 is embedded in the groove 13. A second external thread is welded to the bottom of the plate 15. The second external threaded rod 16 is located inside the slide groove 19. The surface of the second external threaded rod 16 is fitted with a second nut 17. One end of the second nut 17 is attached to the bottom of the mounting strip 3. The cutter head 4 is installed inside the anti-wear ring 14. By installing the second external threaded rod 16 and the second nut 17, when installing the anti-wear ring 14, the insert plate 15 can be directly embedded into the groove 13 until the second external threaded rod 16 is located inside the slide groove 19. Then, the second nut 17 is rotated to increase the friction between the mounting strip 3 and the insert plate 15, thereby fixing the insert plate 15 and then fixing the anti-wear ring 14, ensuring the stability of the anti-wear ring 14 during use.
[0027] A cylinder 6 is mounted on the top of the mounting strip 3. One end of the cylinder 6 is connected to a pressing plate 7. A fixing plate 5 is welded to the top of the mounting strip 3. The side of the fixing plate 5 is attached to the surface of the cutter head 4. The inner wall of the pressing plate 7 is attached to the surface of the cutter head 4. By installing the pressing plate 7 and the fixing plate 5, when the cutter head 4 is installed on the mounting strip 3, the cylinder 6 can control the pressing plate 7 to move until the inner wall of the pressing plate 7 is attached to the surface of the cutter head 4. Then, the fixing plate 5 and the pressing plate 7 are used to press and fix the cutter head 4, thereby further improving the stability of the cutter head 4 after installation.
[0028] A fixing plate 10 is welded to the side of the cylinder 6. The fixing plates 10 are symmetrically distributed. A first external threaded rod 11 is welded to the top of the mounting strip 3. The first external threaded rod 11 passes through the fixing plate 10. A first nut 12 is sleeved on the surface of the first external threaded rod 11. One end of the first nut 12 is attached to the top of the fixing plate 10. By installing the first external threaded rod 11, when installing the cylinder 6, the first external threaded rod 11 can pass through the fixing plate 10. Then, the first nut 12 is sleeved on the surface of the first external threaded rod 11 until one end of the first nut 12 is attached to the top of the fixing plate 10. At this time, the cylinder 6 can be fixed after installation, ensuring the stability of the cylinder 6 during use.
[0029] The insert plate 15 is symmetrically distributed. The other end of the second external thread rod 16 is welded with a baffle 18. The second nut 17 is located between the baffle 18 and the insert plate 15. By installing the baffle 18, the baffle 18 can provide a limiting effect for the second nut 17, so that the second nut 17 will not come off the second external thread rod 16, which is very convenient to use.
[0030] The conversion device 1 has a mounting plate 2 welded to its surface. A second slot 20 is opened on the back of the mounting plate 2. An anti-slip pad 21 is glued inside the second slot 20. By installing the anti-slip pad 21, the friction between the mounting plate 2 and the installation position can be increased, thereby improving the overall stability of the mechanism after installation.
[0031] A first groove 8 is formed on the inner wall of the extrusion plate 7, and an anti-slip strip 9 is bonded inside the first groove 8. By installing the anti-slip strip 9, the friction between the cutter head 4 and the extrusion plate 7 can be increased, thereby further improving the stability of the cutter head 4 after installation.
[0032] The working principle of the tool changing mechanism of this five-axis CNC machining center is as follows: When using this mechanism, cylinder 6 should be installed first. At this time, the first external thread rod 11 passes through the fixing plate 10. Then, the first nut 12 is sleeved on the surface of the first external thread rod 11 until one end of the first nut 12 is attached to the top of the fixing plate 10. This provides a fixed effect for cylinder 6 after installation. Then, the anti-wear ring 14 is installed. When installing the anti-wear ring 14, the insert plate 15 can be directly embedded into the groove 13 until the second external thread rod 16 is located inside the slide groove 19. Then, the second nut 17 is rotated to increase the pressure. The friction between the mounting strip 3 and the insert plate 15 secures the insert plate 15, which in turn secures the anti-wear ring 14. The mechanism is then ready for use. When using this mechanism, the mounting strip 3 is connected to one end of the conversion device 1, and the anti-wear ring 14 is fitted inside the mounting strip 3. A groove 13 is formed inside the mounting strip 3, and a sliding groove 19 is formed at the top of the mounting strip 3. The insert plate 15 is welded to the surface of the anti-wear ring 14, and the insert plate 15 is embedded inside the groove 13. Simultaneously, a second external threaded rod 16 is welded to the bottom of the insert plate 15. This second external threaded rod 16 is located inside the sliding groove 19 and is a second external thread. A second nut 17 is fitted onto the surface of rod 16. One end of the second nut 17 is attached to the bottom of the mounting strip 3, allowing the cutter head 4 to be installed inside the anti-wear ring 14. In this case, the anti-wear ring 14 replaces the direct contact between the mounting strip 3 and the cutter head 4. During subsequent use of this mechanism, wear will occur on the surface of the anti-wear ring 14. When the anti-wear ring 14 wears down, the second nut 17 can be rotated to release the fixing effect of the insert plate 15, allowing the anti-wear ring 14 to be removed and replaced. This improves the installation structure of the tool changing mechanism. No complete replacement is required, reducing costs during use. After the cutter head 4 is installed, a cylinder 6 is installed on the top of the mounting strip 3, and a pressing plate 7 is connected to one end of the cylinder 6. A fixing plate 5 is welded to the top of the mounting strip 3. The side of the fixing plate 5 is attached to the surface of the cutter head 4, and the inner wall of the pressing plate 7 is attached to the surface of the cutter head 4. When the cutter head 4 is installed on the mounting strip 3, the cylinder 6 can control the pressing plate 7 to move until the inner wall of the pressing plate 7 is attached to the surface of the cutter head 4. Then, the fixing plate 5 and the pressing plate 7 press and fix the cutter head 4, thereby further improving the stability of the cutter head 4 after installation.
[0033] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
