[0002] Clamps play a crucial role in the machining of aluminum profiles in CNC machining centers. Traditional fixtures often have limitations and cannot meet the unique demands of aluminum profile machining. Aluminum profiles, with their lightweight, high strength, and corrosion resistance, are widely used in aerospace, automotive, construction, and other fields. However, due to the diverse shapes and sizes of aluminum profiles and the high precision required for machining, traditional fixtures lack uniform clamping force distribution, guaranteed positioning accuracy, and adaptability to the diverse shapes of aluminum profiles.

[0003] At present, with the development of automation and intelligence in industrial production, higher requirements are placed on the rapid clamping and efficient production of fixtures. The clamping function of traditional fixtures is relatively simple and the operation is complicated, which makes it difficult to adapt to the production rhythm of modern CNC machining centers. At the same time, the fixtures cannot adapt to the processing of aluminum profiles of different specifications in actual use, which is not convenient for practical use.

[0004] Therefore, a special fixture for aluminum profile CNC machining center is proposed. Utility Model Content

[0023] 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.

[0024] Example 1: Please refer to Figure 1-6The utility model provides a technical solution: a special fixture for a CNC machining center of an aluminum profile, comprising a shell 1, a mounting table 2 installed inside the shell 1, two support plates 3 installed inside the mounting table 2 for rotation, a fixture table 4 installed on the opposite side surfaces of the two support plates 3, two limit openings 5 are provided on the top of the fixture table 4, the limit openings 5 are used to limit the moving position of the screw block 8, making its movement more stable, a bidirectional screw 6 is installed inside the fixture table 4 for rotation, a drive motor 7 is installed at one end of the bidirectional screw 6, the drive motor 7 is installed on the fixture table 4, two screw blocks 8 are installed on the rod wall of the bidirectional screw 6, and a flexible splint 9 is installed on one side of the two screw blocks 8, and the two screw blocks 8 slide respectively. Installed inside the corresponding limit opening 5, a limited sliding assembly is provided at the bottom of the clamp table 4, a lifting platform 14 is installed on the mounting platform 2, and a lifting mechanism is provided inside the lifting platform 14. The first connecting rod 20 and the second connecting rod 21 are slidingly installed inside the lifting platform 14. By controlling the rotation of the threaded rods 15 on both sides, the first connecting rod 20 and the second connecting rod 21 on the rod wall are driven to move to the opposite or opposite side, thereby pulling the limit blocks 13 on both sides to slide on the limit rod 11, so as to realize the flipping of the clamp table 4 and the clamped material, which is convenient for responding to more complex processing requirements. At the same time, the bidirectional screw 6 in the clamp table 4 drives the two screw blocks 8 to move, so that the flexible splints 9 on both sides can clamp a variety of aluminum profiles of different specifications for processing.

[0025] like Figure 2 As shown, the limit sliding assembly includes a fixed platform 10, which is installed on the clamping platform 4. A limit rod 11 is installed inside the fixed platform 10, and two limit blocks 13 are slidably installed on the rod wall of the limit rod 11. The upper ends of the first connecting rod 20 and the second connecting rod 21 are respectively rotatably installed inside the corresponding limit blocks 13. Through the mutual cooperation of the limit rod 11 and the limit blocks 13 in the limit sliding assembly, it can ensure that the moving direction of the clamping platform (4) is stable during the flipping process, thereby improving the working accuracy and stability of the clamp.

[0026] like Figure 2 and 3 As shown, the lifting mechanism includes two threaded rods 15, and the two threaded rods 15 are rotatably installed inside the lifting platform 14. The lower ends of the two threaded rods 15 pass through the lifting platform 14 and are equipped with driven wheels 16. The two driven wheels 16 are meshed and connected to each other. One side of the two driven wheels 16 is meshed and equipped with a driving wheel 17. One side of the driving wheel 17 is equipped with a rotating motor 18. The rotating motor 18 is installed on the lifting platform 14. The lower ends of the first connecting rod 20 and the second connecting rod 21 are rotatably installed inside the corresponding lifting blocks 19 respectively. The threads of the two threaded rods 15 are set in opposite directions, and the directions of the two lifting blocks 19 are set in opposite directions. By setting the threads of the threaded rods 15 in opposite directions, the fixture table 4 can be accurately flipped and the angle can be adjusted to meet different processing requirements.

[0027] The working principle is as follows: when the present invention is actually used, the aluminum profile is first placed on the top of the clamp table 4, the driving motor 7 is started and the bidirectional screw 6 is driven to rotate. Since the rod wall of the bidirectional screw 6 is threaded with two screw blocks 8, and the two screw blocks 8 are respectively slidably installed in the corresponding limit openings 5 on the top of the clamp table 4, the rotation of the bidirectional screw 6 will make the two screw blocks 8 move closer to or away from each other, thereby driving the flexible splint 9 on one side of the screw block 8 to move, thereby achieving the clamping or loosening of aluminum profiles of different specifications. In this process, the flexible splint 9 ensures that the clamping force is evenly distributed on the surface of the aluminum profile to avoid deformation of the profile.

[0028] At the same time, when processing materials with special shapes, two limit blocks 13 are slidably installed on the limit rod 11 inside the fixed table 10, and the upper ends of the first connecting rod 20 and the second connecting rod 21 are respectively rotatably installed inside the corresponding limit blocks 13. When the clamp table 4 is raised or lowered, the limit blocks 13 slide on the limit rod 11, thereby limiting the flipping angle of the clamp table 4 and ensuring that it remains stable during the movement. How to achieve flipping is started by rotating the motor 18 to drive the driving wheel 17 to rotate, and the driving wheel 17 is engaged with the two driven wheels connected to each other. 16 engages, thereby driving the two threaded rods 15 to rotate. Since the threads of the two threaded rods 15 are set in opposite directions, and the two lifting blocks 19 are respectively threadedly connected to the two threaded rods 15, the rotation of the threaded rod 15 will make the two lifting blocks 19 move closer to or away from each other. The lower ends of the first connecting rod 20 and the second connecting rod 21 are respectively rotatably installed inside the corresponding lifting blocks 19. The movement of the lifting blocks 19 drives the clamp table 4 to rise and fall through the connecting rods, thereby realizing the height position control of the aluminum profile adjustment, meeting the processing requirements of the aluminum profile CNC machining center.

[0029] Example 2: Figure 4 and 6 As shown, during processing, when the shape of the aluminum profile is irregular, a hollow block 22 is installed on one side of the two screw blocks 8, and a limiting component is provided inside the two hollow blocks 22. A plug interface 23 is provided on one side of the two plug interfaces 23, and a movable opening 24 is provided on one side of the two movable openings 24. Special-shaped blocks 25 are slidably installed inside the two movable openings 24. The two flexible splints 9 are respectively installed on the corresponding special-shaped blocks 25. The special-shaped blocks 25 in the hollow blocks 22 on one side of the screw block 8 can slide in the movable opening 24. By adjusting the position of the screw sleeve 28 on the bolt 27, the protective pad 29 on one side of the screw sleeve 28 and the special-shaped block 25 work together to clamp and limit the aluminum profile.

[0030] The limiting assembly includes two limiting springs 26, both of which are installed on the hollow block 22. A bolt 27 is installed inside the hollow block 22, and a screw sleeve 28 is threadedly installed on the rod wall of the bolt 27. A protective pad 29 is installed on one side of the screw sleeve 28. The upper ends of multiple limiting springs 26 are in contact with the bottom of the corresponding special-shaped block 25 respectively, and the upper ends of the two screw sleeves 28 pass through the corresponding hollow block 22 and are installed with handles. The upper ends of the limiting springs 26 installed on the hollow block 22 are in contact with the bottom of the special-shaped block 25, which plays a role of buffering and auxiliary clamping during the clamping process, thereby realizing the rapid replacement of the flexible splint 9 and ensuring that the clamp can stably clamp irregularly shaped aluminum profiles.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
