Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing equipment technology, specifically a positioning device for processing aluminum alloy doors and windows. Background Technology
[0002] Aluminum alloy doors and windows are widely used in modern buildings due to their high strength, light weight, corrosion resistance, and beautiful appearance. As people's aesthetic preferences change, some irregularly shaped aluminum alloy doors and windows are also gradually coming into view. In the production, processing, and assembly of aluminum alloy doors and windows, ensuring their precise dimensions and stable structure is crucial. This not only relates to the sealing and sound insulation of the doors and windows, but also directly affects the overall safety and aesthetics of the building.
[0003] In the production, processing, and assembly processes of aluminum alloy doors and windows in some enterprises, simple devices are often used to fix the door and window frames. While these devices can meet the fixing requirements to a certain extent, they often fall short when faced with complex and varied door and window frame shapes. In particular, for door and window frames with protruding parts or special structures, traditional fixing methods are prone to processing errors or assembly problems due to unstable clamping. In addition, these simple fixing devices often lack flexibility and cannot adapt to door and window frames of different sizes and shapes, thus limiting production efficiency and quality.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this utility model is to provide a positioning device for processing aluminum alloy doors and windows, so as to solve the problems mentioned in the background art.
[0006] To solve the above technical problems, this utility model provides a positioning device for aluminum alloy door and window processing, including a box and a rotating plate rotatably connected to the top of the box. The box has a hollow structure. The top of the rotating plate has a number of sliding grooves 1 and 2 arranged in a circular array about its axis. The sliding grooves 1 and 2 are staggered. A driving mechanism is fixed on the inner wall of the bottom of the box. A clamping mechanism is fixed on the side of the driving mechanism near the rotating plate.
[0007] The clamping mechanism includes a limiting rod 1 that slides in a sliding groove 1 and a limiting rod 2 that slides in a sliding groove 2. The bottom end of the limiting rod 1 slides against a limiting plate 1, and the bottom end of the limiting rod 2 slides against a limiting plate 2. The top ends of the limiting rod 1 and the limiting rod 2 respectively pass through the sliding groove 1 and the sliding groove 2. The four limiting plates 1 and the four limiting plates 2 are fixedly connected to the same horizontally arranged fixed plate at their close ends. The end of the limiting plate 1 away from the fixed plate is inclined downward, and the end of the limiting plate 2 away from the fixed plate is inclined upward.
[0008] Furthermore, both the first and second slides on the rotating plate extend radially along the length of the rotating plate. A horizontally arranged return spring is fixedly connected to the inner wall of the first slide away from the center of the rotating plate. One end of the return spring near the center of the rotating plate is fixed to the side wall of the limiting rod. Similarly, a horizontally arranged return spring is fixedly connected to the inner wall of the second slide near the center of the rotating plate. One end of the return spring away from the center of the rotating plate is fixed to the side wall of the limiting rod.
[0009] Furthermore, a vertical through-channel 1 is provided at the top center of the first limiting plate, and the bottom end of the first limiting rod is provided through the first limiting channel. A vertical through-channel 2 is provided at the top center of the second limiting plate, and the bottom end of the second limiting rod is provided through the second limiting channel. Rollers are rotatably connected to both sides of the bottom end of the first limiting rod, and the rollers roll against the first limiting plate. Rollers with the same structure are rotatably connected to both sides of the bottom end of the second limiting rod, and the rollers roll against the second limiting plate.
[0010] Furthermore, the drive mechanism fixed to the inner wall of the bottom of the box includes an electric push rod fixedly connected to the inner wall of the bottom of the box. The electric push rod is coaxially arranged with the rotating plate. The telescopic end of the electric push rod is coaxially fixedly connected to the bottom end of the fixed plate. A sleeve is coaxially fixedly connected to the side wall of the fixed plate near the rotating plate.
[0011] Furthermore, a limiting rod three is coaxially provided inside the sleeve. A fixing block is fixed to the end of the limiting rod three away from the fixing plate. The fixing block is fixedly connected to the center of the bottom of the rotating plate. Several limiting rods four are fixedly connected to the inner arc wall of the sleeve and are arranged horizontally in a circular array about the axis of the sleeve. The end of the limiting rod four away from the inner arc wall of the sleeve is set towards the limiting rod three.
[0012] Furthermore, the outer arc wall of the limiting rod three is provided with several limiting grooves arranged in a circular array along the axis of the limiting rod three. The end of the limiting rod four away from the inner arc wall of the sleeve slides in the limiting groove, and the several limiting grooves correspond one-to-one with the several limiting rods four.
[0013] Furthermore, the cross-sectional radius of the fixing block is smaller than the cross-sectional radius of the inner arc wall of the sleeve. When the sleeve and the rotating plate abut against each other, the limiting rod three abuts against the fixing plate.
[0014] Furthermore, the area enclosed by the four limiting rods is smaller than the area enclosed by the four limiting rods, and anti-slip particles are provided on the side walls of the four limiting rods that are far apart from each other, and anti-slip particles are provided on the side walls of the four limiting rods that are close to each other.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The extension and retraction of the electric push rod drives the movement of the first and second limit plates, thereby forcing multiple first and second limit rods to perform synchronous centrifugal and centrifugal movements, thus fixing the inner and outer sides of the door and window frame simultaneously. This facilitates assembly by operators and can adapt to clamping and fixing various door and window frames of different sizes and shapes, making it widely applicable.
[0017] 2. By extending and retracting the electric push rod, in conjunction with limit rod three, sleeve and limit rod four, the rotating plate will be driven to swing back and forth to a certain extent during the operation of the clamping mechanism, thereby avoiding the limit rod one or limit rod two from clamping the protruding part on the frame and causing unstable clamping, thus further optimizing the fixing effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see the appendix Figure 1 To be continued Figure 4The present invention provides a technical solution: including a box body 10 and a rotating plate 11 rotatably connected to the top of the box body 10. The box body 10 has a hollow structure. The top of the rotating plate 11 has a plurality of sliding grooves 1 and 2 arranged in a circular array about its axis. The sliding grooves 1 and 2 are staggered. A driving mechanism is fixed on the inner wall of the bottom of the box body 10. A clamping mechanism is fixed on the side of the driving mechanism near the rotating plate 11.
[0027] The clamping mechanism includes a first limiting rod 12 that slides in a first sliding groove and a second limiting rod 14 that slides in a second sliding groove. The bottom end of the first limiting rod 12 slides against a first limiting plate 17, and the bottom end of the second limiting rod 14 slides against a second limiting plate 18. The top ends of the first limiting rod 12 and the second limiting rod 14 respectively pass through the first sliding groove and the second sliding groove. The four first limiting plates 17 and the four second limiting plates 18 are fixedly connected to the same horizontally arranged fixed plate 21 at their respective ends. The end of the first limiting plate 17 away from the fixed plate 21 is inclined downward, and the end of the second limiting plate 18 away from the fixed plate 21 is inclined upward.
[0028] It should be noted that the limiting plates 17 and 18 fixed on the side of the fixed plate 21 are arranged in an alternating manner. When the fixed plate 21 moves along its axial direction, the limiting plates 17 and 18 on the edge of the fixed plate 21 will move accordingly, thereby forcing the corresponding limiting rod 12 or limiting rod 14 to make centripetal or centrifugal movements, thereby clamping the door and window frame to be processed.
[0029] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: the length direction of the first and second slide grooves on the rotating plate 11 is both extended radially along the rotating plate 11. A horizontally arranged return spring 13 is fixedly connected to an inner side wall of the first slide groove away from the center of the rotating plate 11. One end of the return spring 13 near the center of the rotating plate 11 is fixed to the side wall of the first limiting rod 12. A horizontally arranged return spring 15 is fixedly connected to an inner side wall of the second slide groove near the center of the rotating plate 11. One end of the return spring 15 away from the center of the rotating plate 11 is fixed to the side wall of the second limiting rod 14.
[0030] It should be noted that in order to ensure the stability of the first limiting rod 12 and the second limiting rod 14 during sliding, a limiting slider is fixed on the side wall of the first limiting rod 12 near the inner side wall of the first slide groove, and a limiting slide groove is opened on the inner side wall of the first slide groove at the position corresponding to the limiting slider, so as to further ensure the stability of the first limiting rod 12 and the second limiting rod 14 during sliding.
[0031] The return spring 13 and return spring 25 not only prevent excessive clamping from damaging the frame, but also assist the limit rod 12 or limit rod 24 in resetting.
[0032] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a technical solution: a vertically penetrating channel 1 is provided at the top center of the limiting plate 17, and the bottom end of the limiting rod 12 is provided through the channel 1; a vertically penetrating channel 2 is provided at the top center of the limiting plate 18, and the bottom end of the limiting rod 14 is provided through the channel 2; rollers 16 are rotatably connected to both sides of the bottom end of the limiting rod 12, and the rollers 16 roll against the limiting plate 17; rollers 16 with the same structure are rotatably connected to both sides of the bottom end of the limiting rod 14, and the rollers 16 roll against the limiting plate 18.
[0033] It should be noted that: the length direction of channel one is consistent with the length direction of limit plate one 17, and the length direction of channel two is consistent with the length direction of limit plate two 18. Roller 16 always rolls against the side wall of limit plate one 17 or limit plate two 18 near the rotating plate 11. Roller 16 reduces the friction between limit rod one 12 and limit plate one 17 and limit rod two 14 and limit plate two 18.
[0034] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: the driving mechanism fixed on the bottom inner wall of the box 10 includes an electric push rod 20 fixedly connected to the bottom inner wall of the box 10, the electric push rod 20 is coaxially arranged with the rotating plate 11, the telescopic end of the electric push rod 20 is coaxially fixedly connected to the bottom end of the fixed plate 21, and a sleeve 23 is coaxially fixedly connected to the side wall of the fixed plate 21 near the rotating plate 11.
[0035] The sleeve 23 is coaxially provided with a limiting rod 3 22. The end of the limiting rod 3 22 away from the fixed plate 21 is fixed with a fixing block 25. The fixing block 25 is fixedly connected to the center of the bottom of the rotating plate 11. Several limiting rods 4 24 are fixedly connected to the inner arc wall of the sleeve 23 and are arranged horizontally in a circular array about the axis of the sleeve 23. The end of the limiting rods 4 24 away from the inner arc wall of the sleeve 23 is set towards the limiting rod 3 22.
[0036] The outer arc wall of the limiting rod 22 has several limiting grooves arranged in a ring array along the axis of the limiting rod 22. The end of the limiting rod 24 away from the inner arc wall of the sleeve 23 slides in the limiting groove. The several limiting grooves correspond one-to-one with the several limiting rods 24.
[0037] The cross-sectional radius of the fixed block 25 is smaller than the cross-sectional radius of the inner arc wall of the sleeve 23. When the sleeve 23 and the rotating plate 11 abut against each other, the limiting rod 22 abuts against the fixed plate 21.
[0038] It should be noted that when it is necessary to fix the aluminum alloy door and window frame, the electric push rod 20 is activated, the telescopic end of the electric push rod 20 extends, and pushes the fixing plate 21 and its clamping mechanism to move towards the rotating plate 11.
[0039] As the fixed plate 21 moves, the limiting rod 3 22 slides in the sleeve 23, while the limiting rod 4 24 slides in the limiting groove of the limiting rod 3 22. During this process, the limiting rod 1 12 and the limiting rod 2 14 of the clamping mechanism move in opposite directions through the first and second grooves respectively, thus simultaneously fixing the inner and outer sides of the door and window frame.
[0040] During the clamping process, if there are protruding parts or irregular shapes in the door and window frame, the rotating plate 11 can be finely adjusted within a certain range. This fine adjustment is achieved by the sliding of the limiting rod 24 in the limiting groove. This ensures that the clamping mechanism can fit tightly against every part of the door and window frame and avoid the problem of unstable clamping.
[0041] The limiting groove is wavy. When the limiting rod 24 slides in the limiting groove, it will move along the trajectory of the limiting groove. Since the sleeve 23 is fixed to the fixed plate 21, the limiting rod 22 is forced to swing, which in turn drives the rotating plate 11 to swing, so as to make the frame swing slightly.
[0042] Once the clamping mechanism has fully clamped the door and window frame, the electric push rod 20 stops working. At this time, the entire positioning device is in a stable state, and the door and window frame is firmly fixed on the rotating plate 11.
[0043] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a technical solution: the area enclosed by the four limiting rods 12 is smaller than the area enclosed by the four limiting rods 14; anti-slip particles are provided on the side walls of the four limiting rods 12 that are far apart from each other; and anti-slip particles are provided on the side walls of the four limiting rods 14 that are close to each other.
[0044] It should be noted that in one possible embodiment, the limiting rod 12 is used to internally support the inner side of the door and window frame, and the limiting rod 14 is used to clamp and fix the outer side of the door and window frame.
[0045] Working principle:
[0046] When it is necessary to fix the aluminum alloy door and window frame, start the electric push rod 20. The telescopic end of the electric push rod 20 extends and pushes the fixing plate 21 and its clamping mechanism to move towards the rotating plate 11.
[0047] As the fixed plate 21 moves, the limiting rod 3 22 slides in the sleeve 23, while the limiting rod 4 24 slides in the limiting groove of the limiting rod 3 22. During this process, the limiting rod 1 12 and the limiting rod 2 14 of the clamping mechanism respectively move in the centripetal and centrifugal directions through the limiting plate 1 17 and the limiting plate 2 18, thereby simultaneously fixing the inner and outer sides of the door and window frame.
[0048] During the clamping process, if there are protruding parts or irregular shapes in the door and window frame, the rotating plate 11 can be finely adjusted within a certain range. This fine adjustment is when the limiting rod 24 slides in the limiting groove and moves along the trajectory of the limiting groove. Since the sleeve 23 is fixed to the fixed plate 21, the limiting rod 22 is forced to swing, which in turn drives the rotating plate 11 to swing, so as to make the frame swing slightly.
[0049] Once the clamping mechanism has fully clamped the door and window frame, the electric push rod 20 stops working. At this point, the entire positioning device is in a stable state, and the door and window frame is firmly fixed to the rotating plate 11.
