Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a high-efficiency positioning and flipping device for CNC drilling and milling centers of aluminum profiles. Background Technology

[0002] In the machining of aluminum profiles, the fixtures equipped in traditional CNC drilling and milling centers have many problems, which greatly limit machining efficiency and accuracy. First, the design of traditional fixtures often only allows for fixing and machining a single working surface of the aluminum profile. When machining the other side of the aluminum profile is required, the profile must first be removed from the fixture, then manually flipped and repositioned before it can be clamped again to continue machining. This process is not only cumbersome and time-consuming, but also prone to positioning errors due to manual operation, affecting machining accuracy. In addition, traditional fixtures have poor adaptability to aluminum profiles of different sizes. Adjusting the fixture to accommodate new materials is a complex and time-consuming process, further reducing production efficiency. These problems not only increase the intensity of manual labor, but also significantly increase production costs, making it difficult to meet the demands of modern industry for efficient, precise, and flexible machining. Therefore, we propose a high-efficiency positioning and flipping device for CNC drilling and milling centers for aluminum profiles. Utility Model Content

[0003] The main purpose of this utility model is to provide a high-efficiency positioning and flipping device for CNC drilling and milling centers of aluminum profiles, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-efficiency positioning and flipping device for a CNC drilling and milling center for aluminum profiles includes a base, a main arm fixedly installed at the rear end of the base, a milling head provided at the front end of the main arm, a movable groove opened at the upper end of the base, an aluminum profile slidably connected in the movable groove, and a flipping mechanism movably installed at the upper end of the base, and the flipping mechanism is slidably connected to the aluminum profile.

[0006] The positioning mechanism includes a first forward and reverse motor, which is embedded in the base. The output end of the first forward and reverse motor is fixedly connected to a first forward and reverse lead screw, which is movably installed in a movable groove. Two movable blocks are threaded onto the first forward and reverse lead screw, and both movable blocks are slidably connected in the movable groove. Movable upright plates are fixedly welded to the upper ends of both movable blocks, and positioning components are movably installed on both movable upright plates, with the two positioning components being symmetrically distributed from left to right.

[0007] Preferably, the threads on the left and right sides of the outer surface of the first positive and negative lead screw are designed in opposite directions, and the two movable blocks are respectively threaded to the left and right sides of the first positive and negative lead screw.

[0008] By adopting the above technical solution: since the threads on the left and right sides of the outer surface of the No. 1 positive and negative lead screw are designed in opposite directions, the two moving blocks will move towards each other along the moving groove, so that the opposite ends of the positioning body contact the left and right sides of the aluminum profile, and complete the lateral clamping and fixing.

[0009] Preferably, the positioning component includes a rotating rod and a movable rod. The rotating rod is movably connected to the upper part of the movable upright plate. One end of the rotating rod is fixedly connected to a first pulley, and the end of the rotating rod away from the first pulley is fixedly connected to a positioning body. The movable rod is movably connected to the lower part of the movable upright plate, and one end of the movable rod is fixedly connected to a second pulley. The second pulley is on the same side as the first pulley and is connected to a transmission belt for transmission.

[0010] By adopting the above technical solution: the No. 2 pulley is connected to the No. 1 pulley through the transmission belt, so the No. 1 pulley also rotates. The rotation of the No. 1 pulley drives the rotating rod fixedly connected to it to rotate, thereby causing the positioning body and its fixed aluminum profile to flip as a whole.

[0011] Preferably, each of the two positioning bodies has a positioning groove at its opposite ends. A second forward and reverse motor is fixedly installed on one side of the positioning body. The output end of the second forward and reverse motor is fixedly connected to a second forward and reverse lead screw, and the second forward and reverse lead screw is movably installed in the positioning groove. The threaded connection of the second forward and reverse lead screw has two clamping blocks.

[0012] By adopting the above technical solution, the No. 2 forward and reverse lead screw controlled by the No. 2 forward and reverse motor further realizes the fine adjustment of the front and rear directions of the aluminum profile, making the clamping more secure and reliable.

[0013] Preferably, the threads on the front and rear sides of the outer surface of the second positive and negative lead screw are designed in opposite directions, and the two clamping blocks are respectively connected to the front and rear threads of the second positive and negative lead screw, and rubber pads are fixedly connected to the opposite ends of the two clamping blocks.

[0014] By adopting the above technical solutions, the entire process is highly automated, greatly improving processing efficiency and reducing the need for manual intervention, making it particularly suitable for large-scale production environments.

[0015] Preferably, the flipping mechanism includes a drive rod, which is rotatably connected to the upper end of the base. One end of the drive rod is fixedly connected to a transmission bevel gear, and the outer side of the transmission bevel gear is connected to a drive bevel gear. The upper end of the drive bevel gear is fixedly connected to a No. 3 forward and reverse motor.

[0016] By adopting the above technical solution, the aluminum profile can be flipped without re-clamping, allowing it to turn smoothly and facilitating processing on the other side. This greatly enhances the functionality of the equipment and eliminates the need for frequent tooling changes. In addition, the No. 1 forward and reverse motor, the No. 2 forward and reverse motor, and the No. 3 forward and reverse motor are all connected to the control system and power supply equipment inside the base via wiring, which is not shown.

[0017] Preferably, the outer surface of the drive rod is provided with a groove, and the interior of the movable rod is provided with a protrusion that cooperates with the groove. The movable rod is slidably connected to the drive rod through the protrusion.

[0018] By adopting the above technical solution: on the one hand, when the drive rod rotates, the movable rod achieves synchronous rotation through the cooperation of the convex strip and the groove; on the other hand, during the movement of the movable upright plate, the movable rod can slide freely on the drive rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through a meticulously designed positioning mechanism, the aluminum profile can be precisely and firmly clamped in both the horizontal and vertical directions. The first positive and negative screw, driven by the first positive and negative motor, allows the two moving blocks to automatically adjust their positions according to the size of the aluminum profile, ensuring the stability of the aluminum profile during processing. In addition, the second positive and negative screw, controlled by the second positive and negative motor, further enables fine adjustment of the aluminum profile in the front and back directions, making the clamping more secure and reliable. This dual clamping mechanism not only improves the stability of the aluminum profile during processing and reduces processing errors caused by aluminum profile displacement, but also greatly improves processing efficiency and reduces the need for manual intervention due to the high degree of automation of the entire process, making it particularly suitable for large-scale production environments.

[0021] 2. The design of the flipping mechanism greatly facilitates the multi-faceted processing of aluminum profiles. The No. 3 forward and reverse motor drives the bevel gear, which in turn drives the drive rod to rotate. The synchronous rotation of the drive rod is achieved by the cooperation between the protrusion on the movable rod and the groove on the drive rod. This ensures that the aluminum profile can be flipped without re-clamping, allowing the aluminum profile to turn smoothly and making it convenient to process the other side. This greatly enhances the functionality of the equipment and eliminates the need for frequent tooling changes. Attached Figure Description

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A high-efficiency positioning and flipping device for a CNC drilling and milling center for aluminum profiles includes a base 1, a main arm 2 fixedly installed at the rear end of the base 1, a milling head 3 provided at the front end of the main arm 2, a movable groove 5 opened at the upper end of the base 1, an aluminum profile 7 slidably connected in the movable groove 5, and a flipping mechanism 6 movably installed at the upper end of the base 1, and the flipping mechanism 6 is slidably connected to the aluminum profile 7.

[0032] In this embodiment, the positioning mechanism 4 includes a first forward and reverse motor 41, which is embedded in the base 1. The output end of the first forward and reverse motor 41 is fixedly connected to a first forward and reverse lead screw 42, which is movably installed in the movable groove 5. Two movable blocks 43 are threadedly connected to the first forward and reverse lead screw 42, and both movable blocks 43 are slidably connected in the movable groove 5. The upper ends of the two movable blocks 43 are fixedly welded to movable upright plates 44, and positioning components 45 are movably installed on the two movable upright plates 44, which are symmetrically distributed from left to right. The threads on the left and right sides of the outer surface of the first forward and reverse lead screw 42 are designed in opposite directions, and the two movable blocks 43 are respectively threaded to the left and right sides of the first forward and reverse lead screw 42. The positioning component 45 includes a rotating rod 46 and a movable rod 49. The rotating rod 46 is movably connected to the upper part of the movable upright plate 44, and one end of the rotating rod 46 is fixedly connected to a first belt pulley 47. A positioning body 48 is fixedly connected to the end of the first pulley 47 away from the first pulley. A movable rod 49 is movably connected to the lower part of the movable upright plate 44. A second pulley 50 is fixedly connected to one end of the movable rod 49. The second pulley 50 is on the same side as the first pulley 47 and is connected to a transmission belt 51. Positioning grooves 481 are opened at the opposite ends of the two positioning bodies 48. A second forward and reverse motor 482 is fixedly installed on one side of the positioning body 48. A second forward and reverse screw 483 is fixedly connected to the output end of the second forward and reverse motor 482. The second forward and reverse screw 483 is movably installed in the positioning groove 481. Two clamping blocks 484 are threadedly connected to the second forward and reverse screw 483. The threads on the front and rear sides of the outer surface of the second forward and reverse screw 483 are designed in opposite directions. The two clamping blocks 484 are respectively threadedly connected to the front and rear sides of the second forward and reverse screw 483. Rubber pads are fixedly connected to the opposite ends of the two clamping blocks 484.

[0033] The above scheme utilizes a first-stage forward and reverse motor 41 to drive a first-stage forward and reverse lead screw 42, allowing two movable blocks 43 to automatically adjust their positions according to the dimensions of the aluminum profile 7, ensuring the stability of the aluminum profile 7 during processing. Furthermore, the second-stage forward and reverse lead screw 483, controlled by a second-stage forward and reverse motor 482, further enables precise adjustment of the aluminum profile 7 in the front-to-back direction, making the clamping more secure and reliable. This dual clamping mechanism not only improves the stability of the aluminum profile 7 during processing and reduces processing errors caused by the displacement of the aluminum profile 7, but also greatly improves processing efficiency and reduces the need for manual intervention due to the high degree of automation of the entire process, making it particularly suitable for large-scale production environments.

[0034] In this embodiment, the flipping mechanism 6 includes a drive rod 61, which is rotatably connected to the upper end of the base 1. One end of the drive rod 61 is fixedly connected to a transmission bevel gear 62, and the outer side of the transmission bevel gear 62 is connected to a drive bevel gear 64. The upper end of the drive bevel gear 64 is fixedly connected to a No. 3 forward and reverse motor 63. The outer surface of the drive rod 61 is provided with a groove 611, and the inside of the movable rod 49 is provided with a protrusion 491 that cooperates with the groove 611. The movable rod 49 is slidably connected to the drive rod 61 through the protrusion 491.

[0035] The above scheme utilizes a No. 3 forward and reverse motor 63 to drive a bevel gear 64, which in turn drives the drive rod 61 to rotate. The movable rod 49's protrusion 491 engages with the drive rod 61's groove 611, enabling the movable rod 49 to rotate synchronously. This ensures that the aluminum profile 7 can be flipped without re-clamping, allowing the aluminum profile 7 to turn smoothly and facilitating processing on its other side. This greatly enhances the equipment's functionality and eliminates the need for frequent tooling changes.

[0036] It should be noted that this utility model is a high-efficiency positioning and flipping device for a CNC drilling and milling center for aluminum profiles. During use, the aluminum profile 7 to be processed is first placed between two positioning bodies 48. Then, the first forward and reverse motor 41 is started. The first forward and reverse motor 41 drives the first forward and reverse lead screw 42, which is fixedly connected to its output end, to rotate. Because the threads on the left and right sides of the outer surface of the first forward and reverse lead screw 42 are designed in opposite directions, when it rotates, the two movable blocks 43 will move towards each other along the movable groove 5. They respectively drive the movable vertical plate 44 welded above to approach the aluminum profile. As the aluminum profile 7 moves, the positioning element 45 on the movable upright plate 44 approaches the aluminum profile 7 until the opposing ends of the positioning body 48 contact the left and right sides of the aluminum profile 7, completing the lateral clamping and fixing. Next, the second forward and reverse motor 482 is started, driving the second forward and reverse lead screw 483, which is fixedly connected to its output end, to rotate. Since the threads on the front and rear sides of the outer surface of the second forward and reverse lead screw 483 are also designed in opposite directions, when it rotates, the two clamping blocks 484 will move towards each other along the positioning groove 481. The clamping blocks 484 gradually approach the aluminum profile 7 and finally pass through... The rubber pad contacts the front and rear surfaces of the aluminum profile 7, applying appropriate pressure to complete the longitudinal clamping and fixing. When it is necessary to process the other side of the aluminum profile 7, the No. 3 forward and reverse motor 63 on the flipping mechanism 6 is activated. The No. 3 forward and reverse motor 63 drives the drive bevel gear 64 fixedly connected to it to rotate. The drive bevel gear 64 meshes with the transmission bevel gear 62, thereby driving the transmission bevel gear 62 and its connected drive rod 61 to rotate. The outer surface of the drive rod 61 is provided with a groove 611, and the inside of the movable rod 49 is provided with a convex strip 491 that cooperates with it. When the drive rod 61 rotates... At that time, the movable rod 49 rotates synchronously through the cooperation of the protrusion 491 and the groove 611. The rotation of the movable rod 49 transmits power through the second pulley 50 fixed at one end. The second pulley 50 is connected to the first pulley 47 through the transmission belt 51, so the first pulley 47 also rotates. The rotation of the first pulley 47 drives the rotating rod 46 fixedly connected to it to rotate, thereby causing the positioning body 48 and its fixed aluminum profile 7 to flip as a whole. After the flip is completed, the surface of the aluminum profile 7 that was originally facing down flips to the top, which is convenient for operation on the new processing surface.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
