Abstract
Description
Technical Field
[0001] This utility model relates to a loop scanner, specifically an angle-adjustable loop scanner. Background Technology
[0002] A looper scanner is a key inspection device used in industrial production lines (such as steel rolling and continuous casting). It is mainly used to monitor and control the shape and position of loops formed in strips, plates or wires during processing in real time.
[0003] A loop scanner consists of a base, an angle adjustment structure, and a scanning probe. The scanning probe is usually mounted on the base via the angle adjustment structure. The angle adjustment structure allows the scanner to change its monitoring angle to adapt to different process requirements, ensuring the stability of the production process and the surface quality of the materials.
[0004] Common angle adjustment structures are divided into manual adjustment structures and automatic adjustment structures. Manual adjustment structures use mechanical structures (such as rotating brackets or bolt fixing) to manually adjust the sensor tilt angle, which is suitable for fixed processes or low-frequency adjustment scenarios. Automatic adjustment structures are suitable for high-frequency or dynamic process requirements, and often use worm gear meshing for adjustment; they can be precisely controlled through a remote control system.
[0005] During the production process, the operation of production equipment and the collision between products and production equipment make the working environment of the looper scanner quite complex. Especially in scenarios such as high-speed rolling, continuous casting, or heavy material processing, mechanical vibration is difficult to avoid. When the vibration intensity is strong, the self-locking function between the worm and the worm wheel will be lost (severe vibration may drive the worm to rotate, thereby driving the worm wheel to rotate), which will cause the scanner to rotate passively and change the monitoring angle, thus making it impossible to accurately monitor the stability of the ongoing production process and the surface quality of the material. Utility Model Content
[0006] The purpose of this invention is to provide an angle-adjustable loop scanner to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An angle-adjustable loop scanner, including a base;
[0009] It also includes a scanner body; the scanner body is fixed to the base via a connecting rod and a worm gear rotatably mounted thereon.
[0010] A worm gear that is rotatably mounted on the base and meshes with the worm wheel;
[0011] It also includes a secondary limiting component, which is disposed on the base, including a movable clamping plate for radially compressing the worm gear and an elastic component for providing radial compressive force to the movable clamping plate;
[0012] An adjusting member is provided, which can drive the elastic element to reset so that the movable clamping plate is disengaged from the worm gear.
[0013] As described above, the angle-adjustable loop scanner includes a secondary limiting component that further comprises a third rotating shaft fixedly mounted on the worm gear; a fixing block that slides and engages with the movable clamping plate is fixedly mounted on the base; and a fixing clamping plate that rotates and engages with the third rotating shaft is fixedly mounted at one end of the fixing block.
[0014] As described above, the angle-adjustable loop scanner includes: the elastic element comprising a movable block slidably mounted on the fixed block and fixedly connected to the movable clamping plate; a wedge block fixedly mounted on one end of the movable block away from the movable clamping plate; a pressing block cooperating with the wedge block slidably mounted inside the fixed block; a baffle fixedly mounted on the base; a spring provided between the pressing block and the baffle; and both ends of the spring abutting against the baffle and the pressing block, respectively.
[0015] The angle-adjustable loop scanner described above includes: an adjusting component comprising a motor fixedly mounted on the base, a first rotating shaft fixedly mounted on the output end of the motor; a centrifugal disc fixedly mounted on the first rotating shaft; multiple sets of centrifugal blocks slidably fitted onto the centrifugal disc, and the centrifugal blocks being equidistantly arranged along the circumference of the centrifugal disc; telescopic columns fixedly mounted on the centrifugal blocks; a movable sleeve sleeved on the first rotating shaft; a telescopic sleeve slidably fitted onto the movable sleeve and slidingly fitted onto the telescopic column; and a sliding turntable slidably fitted onto the first rotating shaft and rotatably connected to the extrusion block.
[0016] The angle-adjustable loop scanner described above includes an adjustment mechanism that further includes a second rotating shaft rotatably mounted on the base, the second rotating shaft being connected to the third rotating shaft via a belt; a fixed turntable that cooperates with the sliding turntable is fixedly mounted on the second rotating shaft.
[0017] As described above, the angle-adjustable looper scanner has multiple sets of second toothed blocks fixedly installed on the fixed turntable; and multiple sets of first toothed blocks that can mesh with the second toothed blocks are fixedly installed on the sliding turntable.
[0018] As described above, the angle-adjustable loop scanner has an arc-shaped surface where the movable clamp plate mates with the third rotating shaft.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the action of the adjusting component can drive the elastic component to reset, so that the movable clamping plate is disengaged from the squeezing state with the worm gear, thereby facilitating the adjustment of the monitoring angle. When the adjusting component stops moving, the elastic component can drive the adjusting component to reset, thus enabling multiple angle adjustments of the scanner and facilitating accurate monitoring of the looper during production. The secondary limiting component restricts the rotation of the worm gear, further fixing the monitoring angle of the scanner body and preventing the worm gear from rotating due to external factors such as severe vibration during production, which would change the monitoring angle of the scanner body and affect the accuracy of looper monitoring. The cooperation between the adjusting component and the secondary limiting component can effectively improve the convenience of monitoring angle. After the adjusting component drives the movable clamping plate to disengage from the squeezing state with the worm gear, it drives the worm gear to rotate to adjust the monitoring angle, which can effectively determine the adjustment node and improve adjustment efficiency.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0041] Please see Figures 1-6 As one embodiment of this utility model, the angle-adjustable loop scanner includes a base 1;
[0042] It also includes a scanner body 2; the scanner body 2 is fixed to a worm gear 202 rotatably mounted on the base 1 via a connecting rod 201 fixed thereto;
[0043] The worm 1401 is rotatably mounted on the base 1 and meshes with the worm gear 202;
[0044] It also includes a secondary limiting component, which is disposed on the base 1, including a movable clamping plate 1101 for radially pressing the worm gear 1401 and an elastic component for providing radial pressing force to the movable clamping plate 1101;
[0045] An adjusting member is provided, which can drive the elastic member to reset so that the movable clamp 1101 is disengaged from the worm gear 1401.
[0046] In this embodiment, the device is bolted to the base 1 to fix the scanner, which facilitates the scanner body 2 to monitor the looper.
[0047] When the worm gear 1401 rotates, it can drive the worm wheel 202 to rotate through meshing, thereby driving the connecting rod 201 to rotate, which in turn drives the scanner body 2 to rotate, thereby changing the angle between the scanner body 2 and the base 1, and adjusting the monitoring angle of the scanner body 2.
[0048] When the worm 1401 is stationary, the monitoring angle of the scanner body 2 is relatively fixed through the meshing of the worm wheel 202 and the worm 1401.
[0049] The secondary limiting component can restrict the rotation of the worm gear 1401, thereby fixing the monitoring angle of the scanner body 2; the elastic component provides radial extrusion force on the worm gear 1401 through the movable clamping plate 1101, which can clamp the worm gear 1401, thereby preventing the worm gear 1401 from rotating, further fixing the monitoring angle of the scanner body 2, and avoiding the worm gear 1401 from rotating due to external factors such as severe vibration during the production process, which would change the monitoring angle of the scanner body 2 and affect the accuracy of the looper monitoring.
[0050] When the monitoring angle of the scanner body 2 needs to be changed due to production requirements, the elastic element is reset by the adjusting component, thereby removing the radial compressive force provided to the movable clamping plate 1101 on the worm gear 1401, causing the movable clamping plate 1101 to disengage from the worm gear 1401. At this time, an external force can be applied to drive the worm gear 1401 to rotate, thereby adjusting the monitoring angle of the scanner body 2.
[0051] As a further embodiment of this utility model, the secondary limiting component also includes a third rotating shaft 14 fixedly installed on the worm gear 1401; a fixing block 10 that slides and engages with the movable clamping plate 1101 is fixedly installed on the base 1; and a fixing clamping plate 1001 that rotates and engages with the third rotating shaft 14 is fixedly installed at one end of the fixing block 10.
[0052] In this embodiment, when the third rotating shaft 14 rotates, it can drive the worm gear 1401 to rotate synchronously, thereby driving the connecting rod 201 to rotate through the meshing action with the worm wheel 202, so as to adjust the monitoring angle of the scanner body 2, so as to accurately monitor the real-time status of the looper during the production process, avoid product quality reduction due to abnormal looper status, and avoid the occurrence of dangerous accidents.
[0053] When the elastic element provides radial force, the movable clamping plate 1101 will slide in the fixed block 10 to gradually approach the fixed clamping plate 1001, so that the distance between the fixed clamping plate 1001 and the movable clamping plate 1101 gradually decreases. When the movable clamping plate 1101 contacts the third rotating shaft 14, the radial force provided by the elastic element can increase the friction between the movable clamping plate 1101 and the third rotating shaft 14, thereby increasing the difficulty of rotating the third rotating shaft 14, thus avoiding the worm gear 1401 from rotating due to external factors such as severe vibration during the production process, which would change the monitoring angle of the scanner body 2 and affect the accuracy of the looper monitoring.
[0054] As a further embodiment of this utility model, the elastic element includes a movable block 11 slidably mounted on the fixed block 10 and fixedly connected to the movable clamping plate 1101; a wedge block 1102 is fixedly mounted on one end of the movable block 11 away from the movable clamping plate 1101; a pressing block 8 that cooperates with the wedge block 1102 is slidably mounted inside the fixed block 10; a baffle 101 is fixedly mounted on the base 1; a spring 9 is provided between the pressing block 8 and the baffle 101; and the two ends of the spring 9 respectively abut against the baffle 101 and the pressing block 8.
[0055] In this embodiment, when the spring 9 is stationary, the elastic force of the spring 9 will act on the pressing block 8, so that the pressing block 8 tends to move; at this time, the pressing block 8 and the wedge block 1102 cooperate with each other to press the movable clamping plate 1101 through the movable block 11, so that the movable clamping plate 1101 presses the third rotating shaft 14 to restrict the rotation of the third rotating shaft 14.
[0056] When the adjusting component moves, it will drive the squeezing block 8 to move in the direction of the spring 9, so that the squeezing block 8 and the wedge block 1102 gradually disengage; and compress the spring 9; when the squeezing block 8 and the wedge block 1102 are completely disengaged, the wedge block 1102 can move freely in the fixed block 10, so that the movable clamping plate 1101 can move freely in the fixed block 10; that is, the squeezing force between the movable clamping plate 1101 and the third rotating shaft 14 disappears, and the third rotating shaft 14 can rotate. At this time, driving the third rotating shaft 14 to rotate can adjust the monitoring angle of the scanner body 2.
[0057] After the angle adjustment is completed, the adjusting component stops moving. At this time, the elastic force of the spring 9 will drive the pressing block 8 to move away from the spring 9. During the movement, the pressing block 8 will contact the inclined surface of the wedge block 1102 and press the wedge block 1102 after contact, so as to drive the wedge block 1102 to move towards the third rotating shaft 14. Thus, the movable clamping plate 1101 will move towards the third rotating shaft 14 radially through the movable block 11, so as to press the third rotating shaft 14 and make the third rotating shaft 14 unable to rotate easily.
[0058] The elastic force of spring 9 can offset some of the vibration, effectively reducing the impact of vibration on the scanner.
[0059] As a further embodiment of this utility model, the adjusting component includes a motor 3 fixedly mounted on the base 1, a first rotating shaft 4 fixedly mounted on the output end of the motor 3; a centrifugal disc 5 fixedly mounted on the first rotating shaft 4; multiple sets of centrifugal blocks 501 slidably fitted on the centrifugal disc 5, and the centrifugal blocks 501 are equidistantly arranged along the circumference of the centrifugal disc 5; a telescopic column 502 fixedly mounted on the centrifugal block 501; a movable sleeve 6 sleeved on the first rotating shaft 4; a telescopic sleeve 601 slidably fitted on the movable sleeve 6 and slidingly fitted with the telescopic column 502; and a sliding turntable 7 slidably fitted on the first rotating shaft 4 and rotatably connected to the extrusion block 8.
[0060] In this embodiment, when the motor 3 is activated, it drives the first rotating shaft 4 to rotate, thereby replacing the centrifugal disc 5 to rotate.
[0061] The rotating centrifugal disc 5 will drive the centrifugal block 501 to rotate, and under the action of centrifugal force, the centrifugal block 501 will gradually move away from the first rotating shaft 4, thereby driving the movable sleeve 6 to move away from the motor 3 through the telescopic column 502 and the telescopic sleeve 601. During this process, the telescopic column 502 will move outward inside the telescopic sleeve 601.
[0062] During the movement of the movable sleeve 6, it will squeeze the sliding turntable 7, causing the sliding turntable 7 to move synchronously, thereby driving the squeezing block 8 to move synchronously and compress the spring 9. During this process, the squeezing force of the movable clamping plate 1101 on the third rotating shaft 14 gradually decreases. When the squeezing force of the movable clamping plate 1101 on the third rotating shaft 14 disappears, the difficulty of rotating the third rotating shaft 14 is reduced. At this time, the monitoring angle of the scanner body 2 can be adjusted.
[0063] After adjustment, motor 3 stops rotating. At this time, the elastic force of spring 9 will drive the pressing block 8 to move closer to motor 3, thereby driving the sliding turntable 7 to move synchronously, so as to drive the movable sleeve 6 to move synchronously to reset.
[0064] During the movement of the movable sleeve 6, the telescopic column 502 and the telescopic sleeve 601 will drive the centrifugal block 501 to move towards the first rotating shaft 4, thereby completing the reset. During this process, the telescopic column 502 moves inward inside the telescopic sleeve 601.
[0065] The adjustment mechanism can drive the elastic element to reset, so that the movable clamp 1101 is released from the squeezing state of the worm gear 1401, thereby facilitating the adjustment of the monitoring angle. When the adjustment mechanism stops moving, the elastic element can drive the adjustment mechanism to reset, thus enabling multiple angle adjustments of the scanner and facilitating accurate monitoring of the looper during the production process.
[0066] As a further embodiment of this utility model, the adjusting component also includes a second rotating shaft 13 rotatably mounted on the base 1, and the second rotating shaft 13 is connected to the third rotating shaft 14 by a belt; a fixed rotating disk 12 that cooperates with the sliding rotating disk 7 is fixedly mounted on the second rotating shaft 13.
[0067] As a further embodiment of this utility model, a plurality of second tooth blocks 1201 are fixedly installed on the fixed turntable 12; and a plurality of first tooth blocks 701 that can mesh with the second tooth blocks 1201 are fixedly installed on the sliding turntable 7.
[0068] In this embodiment, when the first rotating shaft 4 rotates, it will drive the sliding turntable 7 to rotate synchronously, thereby driving the first tooth block 701 to rotate.
[0069] When the movable sleeve 6 moves the sliding turntable 7, it will cause the sliding turntable 7 to gradually approach the fixed turntable 12.
[0070] When the movable clamp 1101 is released from the compression state with the worm gear 1401, the first tooth block 701 and the second tooth block 1201 will mesh with each other, thereby driving the fixed turntable 12 to rotate, which in turn drives the second rotating shaft 13 to rotate, and drives the third rotating shaft 14 to rotate through the belt, so as to drive the worm gear 1401 and the worm wheel 202 to cooperate with each other, thereby adjusting the monitoring angle.
[0071] After the adjusting component causes the movable clamping plate 1101 to disengage from the worm gear 1401, it drives the worm gear 1401 to rotate, thereby adjusting the monitoring angle. This effectively determines the adjustment node and improves the adjustment efficiency.
[0072] As a further embodiment of this utility model, the surface on which the movable clamping plate 1101 mates with the third rotating shaft 14 is arc-shaped.
[0073] In this embodiment, the arc-shaped surface can effectively increase the contact area between the movable clamp 1101 and the third rotating shaft 14 to ensure stability.
[0074] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
