Description

Technical Field

[0001] This utility model belongs to the field of debugging rack technology, specifically relating to a door and window debugging rack. Background Technology

[0002] Door and window adjustment racks are used to fix, raise, lower, and adjust the posture of door and window sashes at multiple angles during assembly and maintenance. This facilitates processes such as hinge / slip-stay positioning, hardware installation, and gap and seal tightness correction. They are suitable for door and window assembly lines and after-sales maintenance. Existing devices typically consist of a base and support platform, a vertical guide and lifting transmission unit (such as guide rails with lead screw / chain drive), and a variable-pitch clamping mechanism. Some models incorporate rotation or pitch joints at the support platform and clamping end to adjust the angle and posture of the doors and windows during adjustment.

[0003] In the existing technology, after adjusting the angle of doors and windows fixed on the debugging frame, it is generally necessary to use locking bolts to lock the adjusting shaft to keep the doors and windows at a fixed angle, which is convenient for checking different positions of the doors and windows, installing accessories and debugging. However, due to the need to frequently tighten and loosen the locking bolts, the operation is inefficient and inconvenient. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a door and window adjustment bracket. By setting up a first friction locking rotation mechanism and a second friction locking rotation mechanism, the angle and orientation of doors and windows can be adjusted freely and conveniently, providing convenience and higher efficiency for adjustment work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a door and window adjustment frame, including a base, a first friction locking rotation mechanism installed on the top of the base, a turntable connected to the top of the first friction locking rotation mechanism, a placement platform and a lifting guide rail on the top of the turntable, a first lead screw rotating on the inner side of the lifting guide rail, a slider slidably installed on the inner side of the lifting guide rail, a motor installed on the top of the lifting guide rail, the output end of the motor connected to the first lead screw, a second friction locking rotation mechanism installed on the side of the slider, a clamping device connected to one end of the second friction locking rotation mechanism, both the first and second friction locking rotation mechanisms including a connecting bracket, one end of the connecting bracket connected to a fixed seat, a bearing provided on the inner side of the fixed seat, a rotating shaft provided on the inner side of the bearing, a spring mounting plate slidably provided inside the fixed seat, a disc spring fixedly installed on one side of the spring mounting plate, a friction plate connected to one end of the disc spring, and a friction adjustment screw threaded through and threaded onto one end of the fixed seat.

[0006] The beneficial effects of this utility model are as follows: During the debugging process, the doors and windows can be freely rotated according to the debugging position. This device is equipped with a first friction locking rotation mechanism and a second friction locking rotation mechanism. The friction plate is pressured by a disc spring, thereby forming a high friction force between the friction plate and the end face of the rotating shaft. When no external force is applied to the turntable and the fixed clamping arm, the turntable and the fixed clamping arm can maintain a fixed angle. When it is necessary to adjust the angle of the doors and windows, the turntable can be rotated by applying a horizontal rotational force greater than the friction force between the friction plate and the rotating shaft to the L-shaped telescopic clamping arm. The fixed clamping arm can be rotated by applying a pitch rotational force greater than the friction force between the friction plate and the rotating shaft by moving the L-shaped telescopic clamping arm up and down. When the force is stopped, the turntable and the fixed clamping arm automatically maintain the current angle under the action of friction. With the setting of the first friction locking rotation mechanism and the second friction locking rotation mechanism, the angle and orientation of the doors and windows can be adjusted freely and conveniently, providing convenience and higher efficiency for debugging work.

[0007] For securing doors and windows:

[0008] As a further improvement to the above technical solution: the clamping device includes a fixed clamping arm, an L-shaped telescopic clamping arm is inserted and installed inside the fixed clamping arm, a double-headed motor is installed inside the fixed clamping arm, both output ends of the double-headed motor are connected to a second lead screw, the threads of the two second lead screws are opposite, an air pump is installed on the side of the fixed clamping arm, a clamp mounting groove is provided on the inner side of the L-shaped telescopic clamping arm, a clamping plate is slidably provided on the inner side of the clamp mounting groove, and cylinders are installed at the top and bottom of the L-shaped telescopic clamping arm, the piston rod end of the cylinder is connected to the clamping plate.

[0009] The beneficial effects of this improvement are as follows: When using this device, the door or window to be tested is placed flat on the placement platform, with its front and rear sides parallel to the clamping parts of the L-shaped telescopic clamping arm. Then, the dual-head motor is controlled to drive the second lead screw to rotate. Through the transmission between the second lead screw and the L-shaped telescopic clamping arm, the L-shaped telescopic clamping arm is driven to move closer to each other, so that the clamping surfaces of the L-shaped telescopic clamping arm contact and clamp the front and rear sides of the door or window. Then, the air pump is controlled to drive the cylinder to extend, causing the clamping plates to move closer to each other and clamp the upper and lower edges of the door or window, thus completing the fixation of the door or window.

[0010] As a further improvement to the above technical solution: the connecting bracket of the first friction locking rotation mechanism is connected to the top center of the base, the rotating shaft of the first friction locking rotation mechanism is connected to the bottom center of the turntable, the connecting bracket of the second friction locking rotation mechanism is connected to the side center of the slider, and the rotating shaft of the second friction locking rotation mechanism is connected to the side center of the fixed clamping arm.

[0011] For the control of this device:

[0012] As a further improvement to the above technical solution: a control device is provided on the side of the lifting guide rail, and a control button is provided on the front of the control device.

[0013] The beneficial effects of this improvement are: by issuing control commands through control buttons, the operation of the dual-head motor, motor, air pump and cylinder can be controlled by the PLC inside the control device.

[0014] To adjust the friction between the rotating shaft and the friction plate:

[0015] As a further improvement to the above technical solution: one end of the friction adjusting screw is connected to a hexagonal wrench connector.

[0016] The beneficial effects of this improvement are as follows: the hex wrench connector is used to connect with a hex wrench to rotate the friction adjustment screw and adjust the friction between the shaft and the friction plate.

[0017] To improve the stability of the turntable support:

[0018] As a further improvement to the above technical solution: the bottom of the turntable is connected to four sets of auxiliary support rods, and the bottom end of the auxiliary support rods is equipped with rolling balls, which are in contact with the top of the base.

[0019] The beneficial effects of this improvement are as follows: the four sets of auxiliary support rods enhance the stability of the turntable support. When the turntable rotates, the ball bearings allow the auxiliary support rods to move smoothly with the turntable's rotation, maintaining support stability while reducing resistance.

[0020] To balance the high strength and quiet operation of the friction pads:

[0021] As a further improvement to the above technical solution: the friction pad is a metal-resin composite sheet.

[0022] The beneficial effects of this improvement are as follows: the friction plate structure is a stainless steel base with a resin coating on the friction surface. The resin coating is made of epoxy resin and ceramic particles in a specific ratio, which takes into account both high strength and quietness.

[0023] In summary, the beneficial effects of this case are as follows:

[0024] 1. After the clamping device fixes the door or window to be tested, the control device can control the motor to drive the first lead screw to rotate. Through the transmission between the first lead screw and the slider, the slider is driven to rise, thereby lifting the door or window for easy testing.

[0025] 2. During the debugging process, the doors and windows can be freely rotated according to the debugging position. This device is equipped with a first friction locking rotation mechanism and a second friction locking rotation mechanism. The friction plate is pressured by a disc spring, thereby forming a high friction force between the friction plate and the end face of the rotating shaft. When no external force is applied to the turntable and the fixed clamping arm, the turntable and the fixed clamping arm can maintain a fixed angle. When it is necessary to adjust the angle of the door and window, the turntable can be rotated by applying a horizontal rotational force greater than the friction force between the friction plate and the rotating shaft to the L-shaped telescopic clamping arm. The fixed clamping arm can be rotated by applying a pitch rotational force greater than the friction force between the friction plate and the rotating shaft by moving the L-shaped telescopic clamping arm up and down. When the force is stopped, the turntable and the fixed clamping arm automatically maintain the current angle under the action of friction. Through the setting of the first friction locking rotation mechanism and the second friction locking rotation mechanism, the angle and orientation of the door and window can be adjusted freely and conveniently, providing convenience and higher efficiency for debugging work.

[0026] 3. Insert the hex wrench into the connecting bracket and connect it to the hex wrench connector. By rotating the hex wrench connector, the friction adjustment screw will rotate. The friction adjustment screw extends into the fixed base through the transmission between the friction adjustment screw and the fixed base, thereby changing the position of the spring mounting plate, adjusting the amount of compression of the disc spring, and thus adjusting the friction between the friction plate and the rotating shaft. This ensures that the friction required for adjusting the angle is automatically maintained by the first and second friction locking rotation mechanisms when adjusting doors and windows of different weights.

[0027] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0037] like Figure 1-7 As shown, a door and window adjustment frame includes a base 1. A first friction locking rotation mechanism 2 is mounted on the top of the base 1. A turntable 3 is connected to the top of the first friction locking rotation mechanism 2. A placement platform 4 and a lifting guide rail 5 are provided on the top of the turntable 3. A first lead screw 6 rotates on the inner side of the lifting guide rail 5. A slider 7 is slidably mounted on the inner side of the lifting guide rail 5. A motor 8 is mounted on the top of the lifting guide rail 5. The output end of the motor 8 is connected to the first lead screw 6. A second friction locking rotation mechanism 9 is mounted on the side of the slider 7. One end is connected to a clamping device. Both the first friction locking rotation mechanism 2 and the second friction locking rotation mechanism 9 include a connecting bracket 18. One end of the connecting bracket 18 is connected to a fixed base 19. A bearing 20 is provided on the inner side of the fixed base 19. A rotating shaft 21 is provided on the inner side of the bearing 20. A spring mounting plate 23 is slidably provided inside the fixed base 19. A disc spring 24 is fixedly installed on one side of the spring mounting plate 23. A friction plate 22 is connected to one end of the disc spring 24. A friction force adjusting screw 25 is threaded through and threaded onto one end of the fixed base 19.

[0038] After the clamping device fixes the door and window to be debugged, the control device 27 can control the motor 8 to drive the first lead screw 6 to rotate. Through the transmission between the first lead screw 6 and the slider 7, the slider 7 is driven to rise, thereby lifting the door and window for easy debugging.

[0039] During the debugging process, the doors and windows can be freely rotated according to the debugging position. This device is equipped with a first friction locking rotation mechanism 2 and a second friction locking rotation mechanism 9. The friction plate 22 is pressured by the disc spring 24, thereby forming a high friction force between the friction plate 22 and the end face of the rotating shaft 21. When no external force is applied to the turntable 3 and the fixed clamping arm 10, the turntable 3 and the fixed clamping arm 10 can maintain a fixed angle. When it is necessary to adjust the angle of the doors and windows, the L-shaped telescopic clamping arm 11 is subjected to a force greater than that applied to the friction plate 22 and the end face of the rotating shaft 21. The horizontal rotational force of the friction between shafts 21 can drive the turntable 3 to rotate. By moving the L-shaped telescopic clamping arm 11 up and down, a pitch rotational force greater than the friction between the friction plate 22 and the rotating shaft 21 can be applied, which can drive the fixed clamping arm 10 to rotate. When the force is stopped, the turntable 3 and the fixed clamping arm 10 automatically maintain the current angle under the action of friction. With the setting of the first friction locking rotation mechanism 2 and the second friction locking rotation mechanism 9, the angle and orientation of the doors and windows can be adjusted freely and conveniently, providing convenience and higher efficiency for debugging work.

[0040] Insert a hex wrench into the inside of the connecting bracket 18 and connect it to the hex wrench connector 26. By rotating the hex wrench connector 26, the friction adjustment screw 25 can be rotated. The length of the friction adjustment screw 25 extending into the fixed base 19 is adjusted through the transmission between the friction adjustment screw 25 and the fixed base 19, thereby changing the position of the spring mounting plate 23, adjusting the amount of compression of the disc spring 24, and thus adjusting the friction between the friction plate 22 and the rotating shaft 21. This ensures that the friction required to maintain the adjusted angle is automatically maintained by the first friction locking rotation mechanism 2 and the second friction locking rotation mechanism 9 when adjusting doors and windows of different weights.

[0041] The clamping device includes a fixed clamping arm 10, an L-shaped telescopic clamping arm 11 inserted into the inner side of the fixed clamping arm 10, a dual-head motor 12 installed inside the fixed clamping arm 10, both output ends of the dual-head motor 12 being connected to a second lead screw 13, the threads of the two second lead screws 13 being opposite in direction, an air pump 14 installed on the side of the fixed clamping arm 10, a clamp mounting groove 15 provided on the inner side of the L-shaped telescopic clamping arm 11, a clamping plate 17 slidably provided on the inner side of the clamp mounting groove 15, and cylinders 16 installed on the top and bottom of the L-shaped telescopic clamping arm 11, the piston rod end of the cylinder 16 being connected to the clamping plate 17.

[0042] When using this device, place the door or window to be tested flat on the placement platform 4, ensuring that its front and back sides are parallel to the clamping parts of the L-shaped telescopic clamping arm 11. Then, control the dual-head motor 12 to drive the second lead screw 13 to rotate. Through the transmission between the second lead screw 13 and the L-shaped telescopic clamping arm 11, drive the L-shaped telescopic clamping arm 11 to move closer to each other, so that the clamping surfaces of the L-shaped telescopic clamping arm 11 contact and clamp the front and back sides of the door or window. Then, control the air pump 14 to drive the air cylinder 16 to extend, causing the clamping plates 17 to move closer to each other, clamping the upper and lower edges of the door or window, thus completing the fixation of the door or window.

[0043] The connecting bracket 18 of the first friction locking rotation mechanism 2 is connected to the top center of the base 1, the rotating shaft 21 of the first friction locking rotation mechanism 2 is connected to the bottom center of the turntable 3, the connecting bracket 18 of the second friction locking rotation mechanism 9 is connected to the side center of the slider 7, and the rotating shaft 21 of the second friction locking rotation mechanism 9 is connected to the side center of the fixed clamping arm 10.

[0044] The lifting guide rail 5 has a control device 27 on its side, and the control device 27 has control buttons on its front.

[0045] Control commands are issued via control buttons, and the operation of the dual-head motor 12, motor 8, air pump 14 and cylinder 16 is controlled by the PLC inside the control device 27.

[0046] One end of the friction adjusting screw 25 is connected to a hexagonal wrench connector 26.

[0047] The hex wrench connector 26 is used to connect to a hex wrench to rotate the friction adjusting screw 25 and adjust the friction between the rotating shaft 21 and the friction plate 22.

[0048] The bottom of the turntable 3 is connected to four sets of auxiliary support rods 28. The bottom end of the auxiliary support rods 28 is equipped with rolling balls 29, which are in contact with the top of the base 1.

[0049] The four sets of auxiliary support rods 28 enhance the stability of the turntable 3. When the turntable 3 rotates, the ball bearings 29 allow the auxiliary support rods 28 to move smoothly with the rotation of the turntable 3, maintaining stability while reducing resistance.

[0050] The friction plate 22 is a metal-resin composite plate.

[0051] The friction plate 22 has a stainless steel base with a resin coating on the friction surface. The resin coating is made of epoxy resin and ceramic particles, which balances high strength and quietness.

[0052] The working principle and usage process of this utility model are as follows: When using this device, place the door or window to be tested flat on the placement platform 4, ensuring that its front and rear sides are parallel to the clamping parts of the L-shaped telescopic clamping arm 11. Then, control the double-head motor 12 to drive the second lead screw 13 to rotate. Through the transmission between the second lead screw 13 and the L-shaped telescopic clamping arm 11, the L-shaped telescopic clamping arm 11 is driven to move closer to each other, so that the clamping surfaces of the L-shaped telescopic clamping arm 11 contact and clamp the front and rear sides of the door or window. Then, control the air pump 14 to drive the cylinder 16 to extend (an air pipe is connected between the air pump 14 and the cylinder 16, which is not shown in the accompanying drawings). The device moves the clamping plates 17 closer together to clamp the upper and lower edges of the door and window, thus fixing them in place. Then, the control device 27 controls the motor 8 to drive the first lead screw 6 to rotate. Through the transmission between the first lead screw 6 and the slider 7, the slider 7 rises, thereby raising the door and window for easy adjustment. During adjustment, the door and window can be freely rotated according to the adjustment position. This device is equipped with a first friction locking rotation mechanism 2 and a second friction locking rotation mechanism 9. A disc spring 24 applies pressure to the friction plate 22, thereby creating high friction between the friction plate 22 and the end face of the rotating shaft 21. When no external force is applied to the turntable 3 and the fixed clamping arm 10, both the turntable 3 and the fixed clamping arm 10 can maintain a fixed angle. When it is necessary to adjust the angle of the door or window, by applying a horizontal rotational force greater than the friction force between the friction plate 22 and the rotating shaft 21 to the L-shaped telescopic clamping arm 11, the turntable 3 can be rotated. By moving the L-shaped telescopic clamping arm 11 up and down, by applying a pitch rotational force greater than the friction force between the friction plate 22 and the rotating shaft 21, the fixed clamping arm 10 can be rotated. When the applied force is stopped, under the action of friction, the turntable 3 and the fixed clamping arm 10 automatically maintain the current angle. Inserting a hex wrench into the connecting bracket... The inner side of 18 is connected to the hexagonal wrench connector 26. The hexagonal wrench connector 26 can be rotated by the hexagonal wrench to drive the friction adjustment screw 25 to rotate. The friction adjustment screw 25 extends into the fixed seat 19 through the transmission between the friction adjustment screw 25 and the fixed seat 19, thereby changing the position of the spring mounting plate 23, adjusting the amount of compression of the disc spring 24, and thus adjusting the friction between the friction plate 22 and the rotating shaft 21. This allows the first friction locking rotation mechanism 2 and the second friction locking rotation mechanism 9 to automatically maintain the friction required for the adjusted angle when adjusting doors and windows of different weights.
