[0019] Example 1: like Figure 1-3As shown, a CNC pin fastening machine head for aluminum doors and windows includes a base 1, a first drive assembly, a swing plate 2, a sliding block 3, a pin clamping shaft 4, a pin seat 5, and a second drive assembly. The first drive assembly is located on the top of the base 1, and its output end is connected to the top of the swing plate 2. The top of the swing plate 2 is Y-shaped, and the middle of the swing plate 2 is rotatably mounted on the base 1. The sliding block 3 is located at the bottom of the swing plate 2 along its length, and a sliding plate is connected to the sliding block 3. The sliding plate is slidably mounted on the base 1 along the length of a second mullion 24. The pin clamping shaft 4 is connected to the side of the sliding block 3 closest to the first mullion 22. The second drive assembly is located on the side of the base 1 away from the swing plate 2, and its output end is connected to the pin seat 5. The end of the pin clamping shaft 4 away from the sliding block 3 is slidably mounted in the pin hole of the pin seat 5. The base 1 serves as the basic support component for the entire machine head, providing an installation platform for all other components. The pin holder 5 has a pin hole. The end of the pin clamping shaft 4 away from the sliding block 3 is inserted into the pin hole and can slide freely in the pin hole.

[0020] The first drive assembly includes a motor-driven worm gear reducer 6, a universal joint 7, a left-hand screw 8, a right-hand screw 9, a right-hand nut 10, and a left-hand nut 43.

[0021] The second drive assembly includes a first cylinder 11 and a connecting shaft 12. The first cylinder 11 is mounted on the base 1 along the length direction parallel to the second middle mullion 24 via a first cylinder seat 13. The output end of the first cylinder 11 is connected to a pin seat 5 via the connecting shaft 12. The bottom of the pin seat 5 is slidably mounted on the base 1.

[0022] It also includes a second cylinder 14 and a pin 15. A bracket 16 is provided on the side of the pin seat 5 near the first cylinder 11. The second cylinder 14 is provided on the bracket 16 along the length direction parallel to the first mullion 22. The output end of the second cylinder 14 is connected to the pin 15 through a connector 17. Both the pin seat 5 and the base 1 are provided with pin holes 18 that are adapted to the pin 15, so that the pin 15 can be inserted into or pulled out of the pin hole 18 under the drive of the second cylinder 14, so as to fix the pin seat 5 and the base 1.

[0023] A baffle 26 is provided on the side of the base 1 near the swing plate 2. A support shaft 42 is provided on the baffle 26 along the length direction parallel to the first stile 22. A third cylinder 29 is provided on the support shaft 42 via a second cylinder seat 28. A pressure head 27 is provided at the output end of the third cylinder 29. The second stile 24 is located between the pressure head 27 and the baffle 26. When the second stile 24 is placed in the designated position, it is located between the pressure head 27 and the baffle 26. The pressure head 27 can press the second stile 24 onto the baffle 26 under the drive of the third cylinder 29.

[0024] A reducer base 19 is provided on the top of the first drive assembly, and a first pad 21 for pressing the first mullion 22 is provided below the reducer base 19 via a curved plate 20. The first pad 21 of the first mullion 22 pressing assembly is made of hard rubber and is set vertically to press the first mullion 22 vertically.

[0025] A support block 23 is provided on the side of the base 1 away from the first pad 21, and a second pad 25 is provided at the bottom of the support block 23 for pressing the second mullion 24. The second pad 25 is also made of hard rubber and is used to press the second mullion 24 vertically.

[0026] Working process: Place the first mullion 22 and the second mullion 24 in the designated positions on the machine base 1, ensuring that the first mullion 22 is located below the first pad 21, and the second mullion 24 is located between the pressure head 27 and the baffle 26 and below the second pad 25; start the third cylinder 29, its piston rod extends, driving the pressure head 27 to move towards the baffle 26, pressing the second mullion 24 onto the baffle 26; at the same time, under the action of their own weight and related structures, the first pad 21 and the second pad 25 respectively press the first mullion 22 and the second mullion 24 in the vertical direction, realizing the initial positioning of the profile; An automatic feeding air pipe is installed on the pin holder 5 to place the pins into the pin holes of the pin holder 5, ensuring that the head of the pin faces the pin clamping shaft 4. This pin feeding structure is existing technology and will not be described in detail. The motor-driven worm gear reducer 6 is started, and its output shaft rotates, driving two sets of universal joints 7 to rotate via the transmission shaft. This, in turn, drives the left-hand screw 8 and the right-hand screw 9 to rotate synchronously. Since the threads of the left-hand screw 8 and the right-hand screw 9 are opposite and are threadedly connected to the right-hand nut 10 and the left-hand nut 43 respectively, the right-hand nut 10 and the left-hand nut 43 will move in opposite directions or away from each other along the screw axis. Because both the right-hand nut 10 and the left-hand nut 43 are rotatably connected to the top of the swing plate 2, their movement will cause the swing plate 2 to swing around its central axis. When the swing plate 2 swings, the sliding block 3 at its bottom moves along the length direction parallel to the second mullion 24 under the combined action of the sliding groove of the swing plate 2 and the sliding groove on the base 1, thereby driving the pin clamping shaft 4 to move closer to or away from the pin seat 5; the first cylinder 11 is activated, its piston rod extends, and pushes the pin seat 5 along the guide rail of the base 1 towards the connection part of the first mullion 22 and the second mullion 24 through the connecting shaft 12. During the movement of the pin seat 5, the pin clamping shaft 4 slides in the pin hole. When the pin seat 5 moves to the designated position, the pin is aligned with the preset pin hole on the first mullion 22 and the second mullion 24; under the continuous action of the first drive component, the pin clamping shaft 4 continues to move towards the pin seat 5, pressing the pin... The pin is pushed out from the pin hole and driven into the pin holes of the first mullion 22 and the second mullion 24, completing the pin tightening action. During the pin tightening process, the pin seat 5 needs to be positioned and fixed. The second cylinder 14 can be activated, and its piston rod extends, driving the pin 15 to be inserted into the pin seat 5 and the pin hole 18 on the base 1, preventing the pin seat 5 from shifting during the tightening process. After tightening, the piston rod of the second cylinder 14 retracts, driving the pin 15 to be pulled out of the pin hole 18. After the pin is tightened, the first drive assembly and the second drive assembly move in opposite directions, driving the pin clamping shaft 4 and the pin seat 5 back to their initial positions. The piston rod of the third cylinder 29 retracts, the pressure head 27 releases the second mullion 24, and the tightened profile is removed, completing one work cycle.

[0027] Example 2: The difference between this embodiment and Embodiment 1 lies in the different structures of the first drive assembly, the second drive assembly, and the first mullion 22 clamping assembly. In this embodiment, the first drive assembly includes a second motor 30, a servo right-angle planetary reducer 31, a positive and negative lead screw 32, and a first lead screw nut 33. The second motor 30 is mounted on the top of the base 1. The output end of the second motor 30 is equipped with a servo right-angle planetary reducer 31, which is connected to the output end of the second motor 30 by bolts to reduce the speed and increase the torque. Its output shaft is arranged parallel to the length direction of the second mullion 24. The output end of the servo right-angle planetary reducer 31 is equipped with a positive and negative lead screw 32. Both ends of the positive and negative lead screw 32 are equipped with a first lead screw nut 33. A slider 34 is connected to the first lead screw nut 33. The slider 34 is slidably mounted on the top of the swing plate 2 along the length direction of the swing plate 2. When the second motor 30 is started, its output shaft rotates. After being reduced in speed by the servo right-angle planetary reducer 31, it drives the positive and negative screws 32 to rotate. Since the two threads on the positive and negative screws 32 rotate in opposite directions, the two first screw nuts 33 will move towards or away from each other along the axial direction of the positive and negative screws 32. Through the slider 34, the swing plate 2 swings around the central axis, thereby driving the sliding block 3 and the pin pressing shaft 4 to move, achieving the same driving effect as in Embodiment 1.

[0028] In this embodiment, the second drive assembly includes a third motor 35, a universal joint coupling 36, a left-hand and right-hand trapezoidal lead screw 37, a second lead screw nut 38, and a bearing housing. The third motor 35 is located on the side of the base 1 away from the swing plate 2. The output end of the third motor 35 is connected to the left-hand and right-hand trapezoidal lead screw 37 via the universal joint coupling 36. The middle part of the left-hand and right-hand trapezoidal lead screw 37 is located on the top of the first mullion 22 via the bearing housing. Second lead screw nuts 38 are provided on both sides of the left-hand and right-hand trapezoidal lead screw 37, and the second lead screw nuts 38 are connected to the pin seat 5 via connecting blocks 39. The third motor 35 is bolted to the side of the base 1 away from the swing plate 2, with its output shaft facing the universal joint coupling 36. One end of the universal joint coupling 36 is connected to the output shaft of the third motor 35, and the other end is connected to one end of the left-hand and right-hand trapezoidal lead screw 37, used to compensate for the angular deviation between the two shafts and realize torque transmission. The left-hand and right-hand trapezoidal lead screw 37 has two trapezoidal threads with opposite directions of rotation. Its middle section is supported by a bearing seat on a pre-set bracket 16 at the top of the first mullion 22. The bearing seat is fixedly connected to the bracket 16 by bolts, allowing the left-hand and right-hand trapezoidal lead screw 37 to rotate freely around its own axis. A second nut 38 is threaded onto each of the two threads of the left-hand and right-hand trapezoidal lead screw 37. The second nut 38 is connected to the pin seat 5 via a connecting block 39. The connecting block 39, the second nut 38, and the pin seat 5 are all fixed with bolts. When the third motor 35 is started, its output shaft rotates, driving the left-hand and right-hand trapezoidal lead screw 37 to rotate via the universal joint coupling 36. Because the two threads on the left-hand and right-hand trapezoidal lead screw 37 have opposite directions of rotation, the two second nuts 38 will move towards or away from each other along the axial direction of the left-hand and right-hand trapezoidal lead screw 37. This, in turn, drives the pin seat 5 to move along the guide rail of the machine base 1 via the connecting block 39, achieving the same driving effect as in Embodiment 1.

[0029] The first mullion 22 clamping assembly can also have a connecting seat 40 below the servo right-angle planetary reducer 31, a support 41 on the connecting seat 40, and a first pad 21 for clamping the first mullion 22 at the bottom of the support 41.

[0030] The stable power provided by the drive assembly ensures that the pin receives uniform and sufficient clamping force, guaranteeing a reliable fastening effect. Through the synergistic action of the first and second drive assemblies, and the arrangement of the pads and clamping structures, precise positioning of the first mullion 22 and the second mullion 24 is achieved, ensuring the accuracy of the pin fastening. Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of this utility model are still within the scope of protection of this utility model.
