DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1-Figure 14 As shown, an embodiment of the present invention provides a door and window frame dynamic offset test device, comprising a transmission component 1, the transmission component 1 is used for horizontally conveying the door and window frame to be tested;

[0042] The transmission assembly 1 includes a transmission frame 101, in which a plurality of transmission rollers 102 are evenly arranged, a transmission motor 103 is fixedly installed on the right side of the transmission frame 101, and the transmission motor 103 drives the plurality of transmission rollers 102 to rotate by chain transmission, a support plate frame 106 is fixedly connected to the left side of the transmission frame 101, and a card slot 104 is symmetrically arranged on the upper part of the support plate frame 106, and a fixed roller 105 is rotatably installed on the inner side of the support plate frame 106, and an L-shaped rod 107 is fixedly connected between the support plate frame 106 and the transmission frame 101, and the L-shaped rod 107 passes through the sliding sleeve 507, and the L-shaped rod 107 and the sliding sleeve 507 are fixed as a whole by screws, and the transmission motor 103 is electrically connected to the data processing device 2;

[0043] refer to Figure 3 , Figure 6During the transmission operation, the transmission motor 103 works under the action of the external power supply, and drives multiple transmission rollers 102 to rotate through chain transmission. The friction between the transmission rollers 102 and the door and window frame can drive the door and window frame to move from one side to the other; the card slot 104 is used to cooperate with the card column 301, and the fixed roller 105 is used to provide support and guidance for one side of the door and window frame.

[0044] It also includes a protective shell 3, which is arranged on the upper part of the transmission component 1 to block the light in the external environment. The lower part of the protective shell 3 is symmetrically fixedly connected with a clamping column 301, and the clamping column 301 is engaged with the transmission component 1;

[0045] refer to Figure 1 , Figure 5 , Figure 2 The protective shell 3 is used to block the light in the external environment to prevent the external light from affecting the accuracy of laser ranging. The protective shell 3 can be removed, so as to facilitate the inspection and maintenance of the components inside the protective shell 3 and facilitate later use.

[0046] It also includes a pressing component 4, which is installed on the extension frame 606 and the transmission component 1, and is used to provide vertical downward pressure for the door and window frame; the pressing component 4 includes a force-bearing plate 402, on which a pressing slide bar 401 is slidably installed, and a pressing spring 403 is sleeved on the pressing slide bar 401 and below the force-bearing plate 402, and the lower end of the pressing slide bar 401 is fixedly connected to a containing shell 404, a rotating column 407 is rotatably installed in the containing shell 404, and a pressing cone wheel 405 is rotatably connected to the rotating column 407, and the outer cylindrical surface of the containing shell 404 is a guiding inclined surface 406, and the guiding inclined surface 406 is used to contact and lift the containing shell 404 during transmission with the door and window frame;

[0047] refer to Figure 7 , Figure 8During the downward pressing operation, due to the mutual contact between the door and window frame and the guiding inclined surface 406, the guiding inclined surface 406 gradually contracts from top to bottom, thereby generating an upward thrust, causing the accommodating shell 404 to move upward as a whole, squeezing the downward pressing spring 403. Under the reaction force of the downward pressing spring 403, the downward pressing cone wheel 405 and the upper surface of the door and window frame are in contact with each other. Since the downward pressing cone wheel 405 has a certain taper, this taper provides a certain guiding effect on the downward pressing cone wheel 405. Therefore, the downward pressing cone wheel 405 is easier to be placed on the door and window frame; when the door and window frame moves under the action of the transmission component 1, the door and window frame exerts a certain pressure on the downward pressing cone wheel 405. The friction force generated by 05 is offset at an angle with the rotation direction of the downward pressing cone wheel 405. Therefore, the component of the friction force will cause the downward pressing cone wheel 405 to revolve around the rotating column 407 while rotating. Therefore, it not only provides downward pressure on the door and window frame, but also provides a component along the tangent direction of the rotation of the rotating column 407, so that the protective film on the upper surface of the door and window frame is in a close contact state, avoiding bubbles in the protective film, resulting in uneven surface of the door and window frame, affecting the accuracy of subsequent laser ranging, and if small impurities fall on the upper surface of the door and window frame, the small impurities can also be pushed away by centrifugal force to avoid damage to the upper surface of the door and window frame.

[0048] Data processing device 2, data processing device 2 is arranged on transmission component 1, data processing device 2 is used to collect offset data and centrally process it to form a dynamic offset line graph, data processing device 2 is a computer, and the computer is electrically connected to vertical laser rangefinder 504, tilt laser rangefinder 505, horizontal laser rangefinder 608 and spacing laser rangefinder 607;

[0049] refer to Figure 1 , Figure 2During data processing, the vertical laser rangefinder 504 is used to measure the distance between the vertical laser rangefinder 504 and the upper surface of the door and window frame. As the door and window frame moves, a set of distance values ​​L1 at different time points can be obtained. Similarly, the inclined laser rangefinder 505 can measure the distance value L2 between the inclined laser rangefinder 505 and the inner side of the door and window frame. The horizontal laser rangefinder 608 can measure the distance value L3 between the horizontal laser rangefinder 608 and the outer side of the door and window frame. The distance values ​​at different time points have a small error value when the door and window frame is qualified. If one side of the door and window frame is deformed, the corresponding distance value will have an error value change. For example, if a pit appears on the upper surface of the door and window frame, Then the error value of the distance value L1 will change. If the inner surface of the door and window frame is deformed, the error value of the distance value L2 will change. If the outer surface of the door and window frame is deformed, the error value of the distance value L3 will change. Among them, the error value is the change in the data values ​​measured at different time points. For example, L1 is measured to be 10 cm in the first second and 11 cm in the second second, then the error value is 1. If the error value becomes 3 in the third second, then the upper surface of the door and window frame is deformed. At the same time, the approximate position of the deformation can also be determined. Among them, the laser rangefinder is an existing product, which can measure the distance value between two objects by using the emitted laser. Its specific structure and principle will not be repeated here.

[0050] The adjusting component 6 is arranged on the transmission component 1. The adjusting component 6 includes an adjusting part and an extension frame 606. The adjusting part is used to provide a displacement perpendicular to the movement direction of the door and window frame. The adjusting part includes a light rod 604 and a mounting plate 601 fixedly mounted on the transmission component 1. An adjusting motor 602 is mounted on the mounting plate 601. An adjusting screw rod 603 is fixedly connected to the output end of the adjusting motor 602. An adjusting block 609 is threadedly connected to the adjusting screw rod 603. A sliding plate 605 is fixedly connected to the upper part of the adjusting block 609. The sliding plate 605 is slidably matched with the light rod 604. The sliding plate 605 is fixedly connected to the extension frame 606. The adjusting motor 602 is electrically connected to the data processing device 2.

[0051] refer to Fig.12 , Fig.13 During the adjustment operation, the adjustment motor 602 is powered on to drive the adjustment screw 603 to rotate, the adjustment screw 603 drives the adjustment block 609 to move, and the adjustment block 609 drives the sliding plate 605 and the extension frame 606 to move, thereby driving the downward pressure component 4, the measuring component 5, the side pressure component 7, the spacing laser rangefinder 607, and the horizontal laser rangefinder 608 on the extension frame 606 to move synchronously. The closer the sliding plate 605 is to the fixed roller 105, the smaller the width of the door and window frame is suitable for. Conversely, it is suitable for the door and window frame with a larger width. It can be suitable for door and window frames of different widths.

[0052] The extension frame 606 is fixedly mounted on the adjustment component, and a horizontal laser rangefinder 608 and a spacing laser rangefinder 607 are mounted on the extension frame 606;

[0053] Measuring assembly 5, the measuring assembly 5 is installed on the extension frame 606 and the transmission assembly 1, and the measuring assembly 5 is used to measure the offset of the door and window frame in the vertical and horizontal directions;

[0054] The measuring assembly 5 includes a measuring frame 501, the upper part of which is fixedly connected with a sliding sleeve 507 and a positioning block 502, the positions of the positioning block 502 and the spacing laser rangefinder 607 correspond to each other, the side of the measuring frame 501 close to the workpiece is rotatably connected with an inclined plate 506, the lower part of the measuring frame 501 is fixedly installed with a vertical laser rangefinder 504, the lower part of the inclined plate 506 is fixedly connected with an inclined laser rangefinder 505, the outer side of the sliding sleeve 507 is fixedly connected with a support arm 503, the support arm 503 passes through the inclined plate 506, and the support arm 503 and the inclined plate 506 are fixed as a whole by screws; the support arm 503 includes a horizontal portion 5031 and an arc portion 5032, and the arc portion 5032 provides guidance for the rotation of the inclined plate 506;

[0055] refer to Fig. 9 , Fig.10 , Fig.11 , the spacing laser rangefinder 607 is used to measure the spacing between the spacing laser rangefinder 607 and the positioning block 502, which is used to determine the suitable width of the door and window frame; the vertical laser rangefinder 504 and the tilt laser rangefinder 505 respectively measure the distance values ​​of the upper surface and the inner surface of the door and window frame; the sliding sleeve 507 can slide on the L-shaped rod 107, so the position of the sliding sleeve 507 can be adjusted according to actual conditions, and the sliding sleeve 507 can be fixed by screws after the position is determined; the inclination angle of the inclined plate 506 can be adjusted. When adjustment is required, the screws on the inclined plate 506 are unscrewed, the inclined plate 506 is changed to the required angle, and then the screws on the inclined plate 506 are tightened again, and the friction between the screw and the arc portion 5032 is used to achieve the purpose of locking; the inclined plates 506 with different inclination angles can change the ranging position of the inclined laser rangefinder 505, which is suitable for adjusting the ranging position.

[0056] It also includes a side pressure assembly 7, which is installed on the extension frame 606 and is used to provide lateral pressure for the door and window frame; the side pressure assembly 7 includes a side pressure slide bar 704 slidably installed, and the side pressure slide bar 704 is fixedly connected to a side pressure frame 702 on one side close to the door and window frame, and a rotatable side pressure wheel 701 is rotatably installed on the side pressure frame 702, and a side pressure spring 703 is sleeved on the side pressure slide bar 704, and the side pressure spring 703 is located between the side pressure frame 702 and the extension frame 606;

[0057] refer to Figure 4 , Fig.14 During the side pressure operation, the side pressure wheel 701 will contact the surface of the door and window frame. Under the elastic force of the side pressure spring 703, the side pressure wheel 701 will generate a certain lateral pressure to prevent the door and window frame from shifting horizontally, thereby improving the accuracy of side distance measurement. The side pressure wheel 701 can be a rubber wheel, which has a certain amount of deformability while providing pressure, so that the side pressure wheel 701 can be close to the door and window frame, and also avoid the appearance of bubbles on the side surface, thereby improving the accuracy of distance measurement.

[0058] Working principle: When in use, the downward pressing component 4, the measuring component 5, the side pressing component 7, the spacing laser distance meter 607, and the horizontal laser distance meter 608 on the extension frame 606 are driven by the adjusting components to move to suit the door and window frame products that need to be tested;

[0059] Then, the door and window frame product to be tested is placed on the conveying roller 102 from one side. The door and window frame will contact with the guiding inclined surface 406, which will generate an upward thrust, so that the accommodating shell 404 moves upward as a whole, squeezing the downward pressing spring 403. Under the reaction force of the downward pressing spring 403, the downward pressing cone wheel 405 and the upper surface of the door and window frame are in contact with each other. When the door and window frame moves under the action of the transmission component 1, the friction force generated by the door and window frame on the downward pressing cone wheel 405, due to the angle between the friction force and the rotation direction of the downward pressing cone wheel 405 Therefore, the friction force component will make the downward pressing cone wheel 405 revolve around the rotating column 407 while rotating, thus providing downward pressure on the door and window frame and providing a component along the tangent direction of the rotating column 407, so that the protective film on the upper surface of the door and window frame is in a close contact state, avoiding the uneven surface of the door and window frame due to the retention of bubbles in the protective film, affecting the accuracy of subsequent laser ranging, and if small impurities fall on the upper surface of the door and window frame, the small impurities can also be pushed away by centrifugal force to avoid damage to the upper surface of the door and window frame;

[0060] The transmission component 1 transmits the product. During the transmission process, the vertical laser rangefinder 504 can measure the distance between the vertical laser rangefinder 504 and the upper surface of the door and window frame. As the door and window frame moves, a set of distance values ​​L1 at different time points can be obtained. Similarly, the inclined laser rangefinder 505 can measure the distance value L2 between the inclined laser rangefinder 505 and the inner side of the door and window frame, and the horizontal laser rangefinder 608 can measure the distance value L3 between the horizontal laser rangefinder 608 and the outer side of the door and window frame. The change in the error value can be used to determine whether the surface of the door and window frame is deformed, and it can be intuitively determined whether the door and window frame is deformed and whether the door and window frame is qualified.
