Description

Technical Field

[0001] This utility model relates to the field of door and window assembly clamping technology, and in particular to a clamp for door and window assembly. Background Technology

[0002] In the field of modern architecture, doors and windows are an important component of buildings, and their quality and installation effect directly affect the overall performance, aesthetics, and user experience of the building. With the increasing diversification of architectural design styles and the continuous improvement of requirements for building energy conservation, sound insulation, and safety, the types of doors and windows have become increasingly diverse, covering aluminum alloy doors and windows, PVC doors and windows, wooden doors and windows, and various new composite material doors and windows. Size specifications are also showing a diversified trend, ranging from standard doors and windows for ordinary residential buildings to extra-large doors and windows for large commercial buildings.

[0003] Door and window assembly, as a crucial step in the production and installation of doors and windows, plays a decisive role in ensuring their quality. During assembly, various door and window profiles must be precisely spliced ​​and fixed to ensure the frame has sufficient strength and stability, while also guaranteeing that the doors and windows meet performance standards such as sealing and sound insulation. In this process, door and window assembly clamping technology is paramount. It reliably secures the door and window profiles during assembly, preventing displacement and deformation during welding, riveting, and caulking, providing a stable foundation for subsequent assembly processes, and directly affecting the assembly accuracy and finished product quality.

[0004] Existing door and window assembly clamping technologies have significant drawbacks: Firstly, most adopt a mechanical rigid synchronous structure, where the dynamic coupling between the upper and lower and left and right clamping units cannot be independently cut off. This can easily lead to a situation where one unit is in place but the entire unit stops, resulting in incomplete clamping or problems such as mutual pulling, uneven force on doors and windows, and deformation caused by forced driving. Furthermore, they have poor adaptability and are difficult to be compatible with non-standard sized doors and windows. Secondly, they lack an automated closed loop of "detection-control-locking," relying on manual judgment of the clamping status and step-by-step operation. This not only easily leads to damage to doors and windows or loosening of the assembly due to uncontrolled clamping force, but also significantly reduces work efficiency and poses safety hazards due to manual operation. Overall, they are unable to meet the requirements for high-precision, high-efficiency, and high-safety door and window assembly.

[0005] In summary, existing clamping devices suffer from problems such as incomplete clamping, uneven force distribution, and poor adaptability due to their mechanically rigid synchronous structure. Utility Model Content

[0006] The present invention provides a clamp for assembling doors and windows, which can solve the problems of incomplete clamping, uneven force distribution and poor adaptability caused by the mechanical rigidity of existing clamping equipment.

[0007] A clamp for assembling doors and windows includes a rectangular frame. The rectangular frame includes a top horizontal beam, a bottom horizontal beam, a left vertical beam, a right vertical beam, and a fixing plate in the middle. A top-bottom synchronous clamping device is provided between the top and bottom horizontal beams of the rectangular frame, and a left-right synchronous clamping device is provided between the left and right vertical beams of the rectangular frame. An electromagnetic decoupling device is provided outside the rectangular frame, and the electromagnetic decoupling device is connected to the top-bottom synchronous clamping device and the left-right synchronous clamping device respectively. The upper and lower synchronous clamping device includes an upper and lower drive mechanism, an upper clamping block and a lower clamping block. The upper clamping block is slidably connected to the top crossbeam, and the lower clamping block is fixedly connected to the bottom crossbeam. The left and right synchronous clamping device includes a left and right drive mechanism, a left clamping block and a right clamping block. The left clamping block is fixedly connected to the left vertical beam, and the right clamping block is slidably connected to the right vertical beam.

[0008] Preferably, the electromagnetic decoupling device includes a first electromagnetic clutch and a second electromagnetic clutch, wherein the first electromagnetic clutch is connected to the power output end of the upper and lower drive mechanism, and the second electromagnetic clutch is connected to the power output end of the left and right drive mechanism.

[0009] Preferably, the rectangular frame is provided with a fixing frame, and the fixing frame is fixedly connected to the rectangular frame.

[0010] Preferably, a controller is fixedly installed on the mounting bracket, and the controller is electrically connected to the up-down drive mechanism, the left-right drive mechanism, the first electromagnetic clutch, and the second electromagnetic clutch.

[0011] Preferably, the up-and-down drive mechanism includes a first motor and a first synchronous transmission assembly, the output shaft of the first motor is connected to the first synchronous transmission assembly through a first electromagnetic clutch, and the first motor is fixedly mounted on a fixed frame.

[0012] Preferably, the first synchronous transmission assembly includes a first gear and a first bidirectional rack. The center of the first gear is rotatably connected to a fixed plate, and the center of the first gear on the side away from the fixed plate is fixedly connected to the output end of the first motor. The first bidirectional rack is parallel to the left and right vertical beams of the rectangular frame, and the first bidirectional rack meshes with the first gear.

[0013] Preferably, the left and right drive mechanism includes a second motor and a second synchronous transmission assembly. The output shaft of the second motor is connected to the second synchronous transmission assembly through a second electromagnetic clutch, and the second motor is fixedly mounted on a fixed frame.

[0014] Preferably, the second synchronous transmission assembly includes a second gear and a second bidirectional rack. The center of the second gear is rotatably connected to a fixed plate, and the center of the second gear on the side away from the fixed plate is fixedly connected to the output end of the first motor. The second bidirectional rack is parallel to the top crossbeam of the rectangular frame, and the second bidirectional rack meshes with the second gear.

[0015] Preferably, the upper and lower synchronous clamping devices and the left and right synchronous clamping devices are further provided with detection components, the detection components including a first pressure sensor and a second pressure sensor; The first pressure sensor is embedded in the clamping surface of the upper clamping block facing the door and window; The second pressure sensor is embedded in the clamping surface of the left clamping block facing the door and window; Both the first pressure sensor and the second pressure sensor are electrically connected to the controller.

[0016] Preferably, a guide mechanism is provided between the upper clamping block and the top crossbeam, and between the left clamping block and the left vertical beam. The guide mechanism includes a slide rail and a slider. The slide rail is fixed to the horizontal or vertical beam along the clamping direction; The slider is fixedly connected to the upper clamping block and the left clamping block, and slides in cooperation with the slide rail.

[0017] The beneficial effects of this utility model are that, through the first and second electromagnetic clutches of the electromagnetic decoupling device, the power transmission of the upper and lower, left and right clamping devices can be controlled separately. When one set of clamping is in place, the power can be cut off immediately to ensure that the other set of independent operation is not disturbed. This independent control method avoids the problem of uneven force caused by the other set being forced to stop or interfering with each other when one set of clamping is in place in traditional synchronous clamping. This makes the upper, lower, left and right edges of the door and window uniformly stressed, significantly reducing the deformation or positioning error of the door and window caused by clamping deviation, and improving the assembly dimensional accuracy. In addition, by means of the coordinated work of the controller and the detection component, the entire process of "clamping-detection-power cut-off-locking" can be completed automatically. The pressure sensor provides real-time feedback of the clamping force, and the controller automatically controls the motor and clutch action according to the preset threshold, without the need for manual judgment of the clamping status or manual operation.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 3 As shown in the figure, a door and window assembly clamp provided by this utility model includes a rectangular frame 1. The rectangular frame 1 includes a top horizontal beam, a bottom horizontal beam, a left vertical beam, a right vertical beam, and a fixing plate in the middle. A top and bottom synchronous clamping device 2 is provided between the top and bottom horizontal beams of the rectangular frame 1, and a left and right synchronous clamping device 3 is provided between the left and right vertical beams of the rectangular frame 1. An electromagnetic decoupling device 4 is provided outside the rectangular frame 1. The electromagnetic decoupling device 4 is connected to the top and bottom synchronous clamping device 2 and the left and right synchronous clamping device 3 respectively. The upper and lower synchronous clamping device 2 can achieve synchronous clamping of the door and window in the upper and lower directions, ensuring that the upper and lower edges of the door and window are evenly stressed, avoiding tilting or deformation of the door and window due to unilateral stress. The left and right synchronous clamping device 3 can achieve synchronous clamping of the door and window in the left and right directions, ensuring that the left and right edges of the door and window are balanced and improving the positioning accuracy during assembly. The electromagnetic decoupling device 4 achieves power separation between the upper and lower and left and right clamping devices through electromagnetic control. When one set of clamping devices is in place, its power transmission can be cut off, ensuring that the other set can operate independently without interference. The upper and lower synchronous clamping device 2 includes an upper and lower driving mechanism 21, an upper clamping block 22 and a lower clamping block 23. The upper clamping block 22 is slidably connected to the top crossbeam, and the lower clamping block 23 is fixedly connected to the bottom crossbeam. The left and right synchronous clamping device 3 includes a left and right driving mechanism 31, a left clamping block 32 and a right clamping block 33. The left clamping block 32 is fixedly connected to the left vertical beam, and the right clamping block 33 is slidably connected to the right vertical beam.

[0022] When assembling doors and windows, place the doors and windows to be assembled on the lower clamping block 23 and the left clamping block 32 within the rectangular frame 1. After starting the device, the upper and lower drive mechanism 21 of the upper and lower synchronous clamping device 2 drives the upper clamping block 22 to slide down along the top crossbeam. At the same time, the left and right drive mechanism 31 of the left and right synchronous clamping device 3 drives the right clamping block 33 to slide to the left along the right vertical beam. When the clamping is completed in the upper and lower or left and right directions, the electromagnetic decoupling device 4 cuts off the power transmission of the corresponding direction drive mechanism. The direction in which the clamping is not completed continues to drive the clamping block to move until the overall clamping and fixing of the doors and windows is completed.

[0023] The electromagnetic decoupling device 4 includes a first electromagnetic clutch 41 and a second electromagnetic clutch 42. The first electromagnetic clutch 41 is connected to the power output end of the upper and lower drive mechanism 21, and the second electromagnetic clutch 42 is connected to the power output end of the left and right drive mechanism 31.

[0024] The electromagnetic decoupling device 4 uses a jaw clutch. When the power is off, although the driving and driven sprockets disengage, there is still a small gap and frictional resistance between them. This resistance can counteract the reverse rotation torque of the gears. Especially when the clamping force is not large, it is enough to prevent the gears from easily rotating and maintain short-term clamping stability.

[0025] The first electromagnetic clutch 41 can precisely control the power transmission state of the upper and lower drive mechanisms 21. When the upper and lower clamping is in place, the power is cut off to lock the upper and lower clamping position. The second electromagnetic clutch 42 can independently control the power transmission of the left and right drive mechanisms 31. When the left and right clamping is in place, the power is cut off to ensure that it does not interfere with the upper and lower clamping action.

[0026] When the upper and lower synchronous clamping device 2 is working, the first electromagnetic clutch 41 is engaged, and the power of the upper and lower drive mechanism 21 is transmitted to the actuator through the first electromagnetic clutch 41. When the upper and lower clamping is in place, the first electromagnetic clutch 41 is disengaged, cutting off the power output of the upper and lower drive mechanism 21 and maintaining the upper and lower clamping state. Similarly, when the left and right synchronous clamping device 3 is working, the second electromagnetic clutch 42 is engaged to transmit power. When the left and right clamping is in place, the second electromagnetic clutch 42 is disengaged, realizing the locking of the left and right clamping state.

[0027] The rectangular frame 1 is provided with a fixing frame 5, and the fixing frame 5 is fixedly connected to the rectangular frame 1.

[0028] A controller 6 is fixedly installed on the mounting bracket 5. The controller 6 is electrically connected to the up-down drive mechanism 21, the left-right drive mechanism 31, the first electromagnetic clutch 41, and the second electromagnetic clutch 42.

[0029] The controller 6 enables automated control of the entire fixture, allowing for real-time adjustment of the working states of each drive mechanism, the first electromagnetic clutch 41, and the second electromagnetic clutch 42, thereby improving clamping efficiency and accuracy and reducing human error.

[0030] After receiving an external start signal, the controller 6 simultaneously sends drive commands to the up-down drive mechanism 21 and the left-right drive mechanism 31, and keeps the first electromagnetic clutch 41 and the second electromagnetic clutch 42 engaged. When it detects that the clamping is in place in a certain direction, the controller 6 sends a disengagement command to the electromagnetic clutch in the corresponding direction, while keeping the drive mechanism in the other direction working until it receives a signal that the clamping is in place in both directions, and then controls all drive mechanisms to stop working.

[0031] The up-down drive mechanism 21 includes a first motor 211 and a first synchronous transmission assembly 212. The output shaft of the first motor 211 is connected to the first synchronous transmission assembly 212 through a first electromagnetic clutch 41. The first motor 211 is fixedly mounted on the fixed frame 5.

[0032] The first motor 211 provides stable power, and the first electromagnetic clutch 41 enables controllable power transmission, ensuring the controllability of the up and down clamping action.

[0033] When the upper and lower drive mechanism 21 is started, the first motor 211 outputs power, which is transmitted to the first synchronous transmission component 212 via the first electromagnetic clutch 41. The first motor 211 is fixed to the fixed frame 5. The vibration generated during operation is transmitted to the rectangular frame 1 through the fixed frame 5 to disperse it, so as to avoid the transmission accuracy being affected by the motor shaking. When the upper and lower clamps are in place, the first electromagnetic clutch 41 is disengaged, the first motor 211 idles, and the power is no longer transmitted to the first synchronous transmission component 212.

[0034] The first synchronous transmission assembly 212 includes a first gear 2121 and a first bidirectional rack 2122. The center of the first gear 2121 is rotatably connected to the fixed plate to ensure the coaxiality and stability of the rotation of the first gear 2121 and reduce radial runout during transmission. The center of the first gear 2121 on the side away from the fixed plate is fixedly connected to the output end of the first motor 211 to realize the direct transmission of power from the first motor 211 to the first gear 2121 and improve transmission efficiency. The first bidirectional rack 2122 is parallel to the left and right vertical beams of the rectangular frame 1 and meshes with the first gear 2121. Through the meshing transmission of the first gear 2121 and the first bidirectional rack 2122, the rotational motion of the first motor 211 is converted into the linear motion of the first bidirectional rack 2122. The design of the bidirectional rack can ensure the synchronous movement of the clamping blocks and ensure the symmetry of the upper and lower clamping.

[0035] The power of the first motor 211 is transmitted to the first gear 2121 via the first electromagnetic clutch 41, causing the first gear 2121 to rotate around the pivot point on the fixed plate. Since the first bidirectional rack 2122 meshes with the first gear 2121 and is parallel to the left and right vertical beams, the rotational motion of the first gear 2121 is converted into the vertical motion of the first bidirectional rack 2122, which in turn drives the upper clamping block 22 to slide smoothly along the top crossbeam, achieving synchronous clamping from top to bottom.

[0036] The left and right drive mechanism 31 includes a second motor 311 and a second synchronous transmission assembly 312. The output shaft of the second motor 311 is connected to the second synchronous transmission assembly 312 through a second electromagnetic clutch 42. The second motor 311 is fixedly mounted on the fixed frame 5.

[0037] The second motor 311 provides an independent power source for the left and right clamping, and the second electromagnetic clutch 42 realizes the on-demand transmission of power to ensure the independence of the left and right clamping actions.

[0038] After the left and right drive mechanism 31 is started, the power output by the second motor 311 is transmitted to the second synchronous transmission component 312 through the second electromagnetic clutch 42. The second motor 311 is fixed to the fixed frame 5, and its installation position forms an optimized spatial layout with the first motor 211 to avoid mutual interference during operation. When the left and right clamps are in place, the second electromagnetic clutch 42 is disengaged, the power transmission path of the second motor 311 is cut off, and the right clamping block 33 maintains its current position.

[0039] The second synchronous transmission assembly 312 includes a second gear 3121 and a second bidirectional rack 3122. The center of the second gear 3121 is rotatably connected to the fixed plate to ensure the smoothness and coaxiality of the rotation of the second gear 3121 and reduce transmission noise. The center of the second gear 3121 on the side away from the fixed plate is fixedly connected to the output end of the first motor 211 to realize the direct coupling between the power of the second motor 311 and the second gear 3121, thereby improving transmission efficiency. The second bidirectional rack 3122 is parallel to the top crossbeam of the rectangular frame 1 and meshes with the second gear 3121. The rotational motion is converted into linear motion through the meshing transmission of the second gear 3121 and the second bidirectional rack 3122. The design of the bidirectional rack ensures the synchronous movement of the clamping blocks and guarantees the symmetry and stability of the left and right clamping.

[0040] The power of the second motor 311 is transmitted to the second gear 3121 via the second electromagnetic clutch 42, causing the second gear 3121 to rotate around the pivot point on the fixed plate. Since the second bidirectional rack 3122 meshes with the second gear 3121 and is parallel to the top crossbeam, the rotational motion of the second gear 3121 is converted into the horizontal motion of the second bidirectional rack 3122, which drives the right clamping block 33 to slide smoothly along the right vertical beam, achieving synchronous clamping on both sides.

[0041] The upper and lower synchronous clamping device 2 and the left and right synchronous clamping device 3 are also provided with a detection component 7, which includes a first pressure sensor 71 and a second pressure sensor 72. The first pressure sensor 71 is embedded in the clamping surface of the upper clamping block 22 facing the door and window, and detects the pressure value of the upper and lower clamping in real time. When the pressure reaches the preset threshold, it feeds back a signal to the controller 6, triggering the first electromagnetic clutch 41 to stop the upper and lower clamping and prevent excessive clamping from damaging the door and window. The second pressure sensor 72 is embedded in the clamping surface of the left clamping block 32 facing the door and window, and monitors the pressure value of the left and right clamping in real time. When the pressure reaches the standard, it sends a feedback signal, which causes the controller 6 to control the second electromagnetic clutch 42 to cut off the left and right driving power, so as to achieve precise clamping. The first pressure sensor 71 and the second pressure sensor 72 are both electrically connected to the controller 6 to realize the real-time transmission of detection signals, provide a basis for the automated control of the controller 6, and ensure the intelligence and safety of the clamping process.

[0042] When the upper and lower synchronous clamping device 2 is working, the upper clamping block 22 contacts the door and window. The first pressure sensor 71 detects the clamping pressure in real time and transmits the signal to the controller 6. When the pressure reaches the preset threshold, the controller 6 controls the first electromagnetic clutch 41 to disengage and stop the upper and lower clamping. Similarly, when clamping left and right, the second pressure sensor 72 detects the contact pressure between the left clamping block 32 and the door and window. After reaching the threshold, the controller 6 controls the second electromagnetic clutch 42 to disengage and complete the left and right clamping.

[0043] Guide mechanisms 8 are provided between the upper clamping block 22 and the top crossbeam, and between the left clamping block 32 and the left vertical beam. The guide mechanism 8 includes a slide rail 81 and a slider 82. The slide rail 81 is fixed to the horizontal or vertical beam along the clamping direction; The slider 82 is fixedly connected to the upper clamping block 22 and the left clamping block 32, and slides in cooperation with the slide rail 81.

[0044] The slide rail 81 and slider 82 provide a precise guide trajectory for the movement of the clamping block, ensuring the accuracy of the movement direction, reducing the frictional resistance when the clamping block moves, making the movement smoother and more stable, and enhancing the stability of the connection between the clamping block and the crossbeam or vertical beam, avoiding shaking or deviation during the clamping process.

[0045] When the upper clamping block 22 moves under the drive of the upper and lower drive mechanism 21, its connected slider 82 slides along the slide rail 81 on the top crossbeam. The slide rail 81 restricts the upper clamping block 22 to move only in the vertical direction to avoid deviation. When the right clamping block 33 moves, its slider 82 slides along the slide rail 81 on the right vertical beam to ensure that the right clamping block 33 only moves in the horizontal direction. Through the cooperation of the slide rail 81 and the slider 82, the straightness and stability of the clamping process are guaranteed.

[0046] In summary, the door and window assembly fixture provided in this embodiment of the present invention, when in use, firstly, the door and window profiles to be assembled are stably placed inside the rectangular frame 1, so that the bottom of the door and window is in contact with the lower clamping block 23 and the left side is in contact with the left clamping block 32, completing the initial positioning. After the device is started, the controller 6 on the fixing frame 5 receives the external start signal and synchronously sends drive commands to the first motor 211 of the upper and lower drive mechanism 21 and the second motor 311 of the left and right drive mechanism 31. At the same time, it controls the first electromagnetic clutch 41 and the second electromagnetic clutch 42 of the electromagnetic decoupling device 4 to maintain the energized engagement state to ensure that the power can be transmitted normally. In the upper and lower clamping stage, the first motor 211 drives the first gear 2121 to rotate and drives the first bidirectional rack 2122 to move vertically in a linear motion, thereby driving the upper clamping block 22 connected to the first bidirectional rack to slide. At this time, the upper clamping block 22 slides along the slide rail 81 through the slider 82 and steadily moves downward towards the top of the door and window. In the left and right clamping stage, the second motor 311 drives the second gear 3121 to rotate and drives the first gear 2122 to move vertically in a linear motion, thereby driving the upper clamping block 22 connected to the first bidirectional rack to slide. At this time, the upper clamping block 22 slides along the slide rail 81 through the slider 82 and steadily moves downward towards the top of the door and window. The second bidirectional rack moves horizontally in a straight line, which in turn drives the left clamping block 32 to slide along the left vertical beam and slide along the slide rail 81 via the slider 82, precisely approaching the left side of the door and window to the right. As the upper clamping block 22 and the left clamping block 32 continue to move, when a clamping contact is completed in one direction first, the detection component 7 provides real-time feedback. If the upper clamping block 22 contacts the top of the door and window first, the first pressure sensor 71 embedded in its clamping surface immediately detects the contact pressure and transmits the pressure data to the controller 6. When the pressure reaches a preset threshold, the controller 6 quickly sends a power-off command to the first electromagnetic clutch 41. The first electromagnetic clutch 41 disengages, cutting off the power transmission between the first motor 211 and the first synchronous transmission component 212. The first motor 211 idles, and the upper clamping block 22 maintains its current clamping position, achieving vertical clamping and locking. At this time, the controller 6 still maintains the drive command to the second motor 311, and the second electromagnetic clutch 42 continues to engage. The left clamping block 32 continues to move to the right under the drive of the second synchronous transmission component 312 until the left clamping block 32 contacts the left side of the door and window.

[0047] When the left clamping block 32 contacts the left side of the door or window, the second pressure sensor 72 embedded in the clamping surface of the left clamping block 32 detects the contact pressure and transmits the data to the controller 6. When the pressure reaches the preset threshold, the controller 6 sends a power-off command to the second electromagnetic clutch 42. The second electromagnetic clutch 42 disengages, cutting off the power transmission between the second motor 311 and the second synchronous transmission assembly 312. The second motor 311 idles, and the left clamping block 32 locks in position, completing the left and right clamping.

[0048] Finally, after the controller 6 receives signals that the first pressure sensor 71 and the second pressure sensor 72 have both reached their thresholds, it synchronously stops the operation of the first motor 211 and the second motor 311. At this time, under the combined action of the upper and lower synchronous clamping device 2 and the left and right synchronous clamping device 3, the door and window are uniformly stressed and stably fixed in the upper and lower and left and right directions. Moreover, due to the independent control of the electromagnetic decoupling device 4, interference in one direction with the other direction is avoided, providing a precise and reliable clamping foundation for subsequent door and window assembly operations.

[0049] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
