Description

Technical Field

[0001] This invention relates to the field of metal inspection equipment technology, specifically a visual measurement device for easy positioning of aluminum profiles. Background Technology

[0002] In the field of metal inspection, visual measurement equipment for aluminum profile inspection combines automated mechanical structures with visual scanning technology to achieve precise measurement of parameters such as the size and shape of aluminum profiles. This equipment uses a threaded rod to drive the scanner and employs an adaptive clamping design with a stabilizing mechanism to quickly position aluminum profile sheets of different widths and thicknesses. It is suitable for quality inspection stages on aluminum profile production lines, playing a crucial role in improving inspection efficiency and accuracy, and ensuring product quality.

[0003] Traditional aluminum profile measuring equipment has significant shortcomings. In terms of positioning efficiency, traditional equipment often uses fixed clamps, requiring manual adjustment of the clamping position to accommodate different sized plates. This operation is cumbersome and time-consuming, making it difficult to meet batch testing needs. It also suffers from poor compatibility, unable to automatically adapt to variations in aluminum profile thickness or width. For non-standard sized plates, specialized clamps are required, increasing equipment costs and maintenance difficulty. Measurement stability is insufficient, lacking effective shock absorption structures. During scanning, mechanical vibrations can easily cause plate displacement or scanner shake, resulting in measurement data deviations. Furthermore, the fixing mechanisms of traditional equipment are mostly rigid contacts, which may cause indentations or damage to the aluminum profile surface, affecting product appearance quality. Moreover, the inability to dynamically balance clamping forces during fixing leads to inconsistent testing accuracy across different batches, hindering improvements in testing efficiency and reliability.

Initially, the scanner is located at the end of the threaded rod away from the motor.

[0009] According to one embodiment of the present invention, a sliding rod is fixedly connected through the inner surfaces of both ends of the mounting bracket, and a sliding seat is symmetrically slidably sleeved on the outer surfaces of both ends of the sliding rod. The sliding seats are arranged in pairs as a group, and two groups of sliding seats are symmetrically arranged. The upper surface of the sliding seat and the upper surface of the center plate are set to the same horizontal plane, and a fixing seat is fixedly connected to the upper surface of the sliding seat.

[0010] According to one embodiment of the present invention, the fixing base is configured as a near-L-shape, the top of the fixing base is inclined, and a connecting rod is fixedly connected through the fixing base, the connecting rod fixingly connecting the fixing bases in the same group.

[0011] According to one embodiment of the present invention, the stabilizing mechanism includes a deformation groove that extends through the side surface of the fixed base. The top and bottom surfaces of the fixed base are configured as arc-shaped surfaces. An expansion bladder is fixedly fitted inside the deformation groove. Closing plates are symmetrically arranged on both sides of the deformation groove, and the top of the closing plates is fixedly connected to the side surface of the fixed base.

[0012] According to one embodiment of the present invention, a pressure plate is slidably sleeved on the outer surface of the threaded rod, the pressure plate is disposed on the side of the movable seat near the motor, and a spring is fixedly connected to the surface of the pressure plate away from the movable seat.

The connecting groove communicates with the internal cavity of the rotating shaft. The connecting groove also communicates with the internal cavity of the compression bladder through a flexible tube. Pulling one of the connecting rods can pull a set of fixed seats outward along the sliding rod through the sliding seat at its bottom, thereby increasing the distance between the two sets of fixed seats. At this time, the aluminum profile plate to be measured can be placed horizontally on the center plate. Then, the pulling of the connecting rod is released. Under the action of elastic force, the pulled fixed seat begins to return to its original position along the sliding rod. That is, the two sets of fixed seats clamp and fix the plate. At this time, the motor is started. After the motor starts, it drives the threaded rod to rotate.

Then, the scanner on the top of the moving seat completes the scanning measurement of the plate.

[0016] (III) Beneficial Effects

[0017] This invention provides a visual measurement device for inspecting aluminum profiles that facilitates positioning. It offers the following advantages:

[0018] (I) This visual measurement device for aluminum profile inspection, which is easy to position, will cause the two sets of fixing seats to press against the sides of the plate after the fixed seat is automatically reset when the plate is fixed. At this time, the two sets of fixing seats will automatically balance under the action of elasticity, thereby ensuring that the plate is always in the center position of the mounting frame. This not only improves the subsequent measurement accuracy, but also allows the device to automatically adapt to aluminum profiles of various widths, greatly improving the applicability of the device.

[0019] (II) This visual measurement device for aluminum profile inspection, which is easy to position, has a fixed seat that presses against both sides of the plate. Due to the deformation groove set on the top of the fixed seat, the inner surface of the top of the fixed seat is in an elastic deformation state, so that the clamping thickness of the fixed seat is in a variable state. This allows the device to automatically match plates of various thicknesses, further improving the applicability of the device. After the top of the fixed seat is deformed, it will always press against both sides of the plate under the action of elasticity, thus completing the self-adaptive fixation, greatly reducing the cumbersomeness of fixation and improving the measurement efficiency.

[0020] (III) This easily positioned visual measurement device for aluminum profile inspection, after the sheet metal is automatically clamped and fixed, moves closer to the pressure plate as the moving seat moves. Initially, the pressure plate remains stationary due to spring support. The moving seat then begins to compress the compression bladder. As the compression bladder deforms, it moves synchronously towards the motor side along with the pressure plate. During compression, the internal air pressure is transferred to the expansion bladder in the fixed seat, increasing the air pressure and causing the bottom of the fixed seat to expand downwards, ultimately pressing firmly against the upper surface of the sheet metal. This ensures the stability of the sheet metal during measurement, preventing measurement accuracy issues caused by mechanical vibrations between the sheet metal and the scanner. Simultaneously, the compression bladder's internal air pressure is transferred to the connecting groove on the mounting frame, increasing the air pressure within the groove. This increases the internal air pressure of the rotating shaft connected to it, which in turn increases the internal air pressure of the deformation bladder connected to it on the outside of the sleeve. This causes the bonding plate to move outward, expanding outward. Ultimately, this causes the support plate connected by the connecting plate to expand outward, resulting in the rubber plate on the outside of the support plate exerting a compressive force on the lower surface of the sliding seat. This ensures air pressure support for the bottom of the sliding seat during measurement. Combined with the expansion bladder, this provides enhanced air pressure fixation for the upper and lower sides of the plate, further preventing measurement accuracy issues caused by different frequencies of vibration between the plate and the scanner. At the same time, the initial combination of the ring-shaped rubber plates significantly reduces the frictional resistance of the sliding seat when it moves left and right, allowing the fixing seat to better fix the plate and preventing the fixing seat from being affected by the frictional resistance of the sliding seat, which could lead to different clamping forces between the two sets of fixing seats and affect the fixing effect.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] First embodiment: as follows Figures 1 to 8As shown, the present invention provides a technical solution: a visual measurement device for aluminum profile inspection that is easy to position, including a mounting frame 1, the mounting frame 1 being horizontally arranged, and support legs 2 being symmetrically fixedly connected to the outer surfaces of both ends of the mounting frame 1, and further including:

[0032] Measuring mechanism 3 is fixedly installed on mounting bracket 1;

[0033] Stabilizing mechanism 5 is also fixedly installed on mounting bracket 1. Stabilizing mechanism 5 and measuring mechanism 3 work together.

[0034] The measuring mechanism 3 includes a center plate 31, which is symmetrically fixedly connected to the upper surface of the middle part of the mounting frame 1. Mounting plates 32 are symmetrically fixedly connected to the outer surfaces of both ends of the mounting frame 1. A threaded rod 33 is rotatably connected to the inner surface of the mounting plate 32. A motor 34 is rotatably connected to the input end of the threaded rod 33. The motor 34 is fixedly installed on the outer surface of the mounting plate 32.

[0035] Two threaded rods 33 are provided. A transmission belt 35 is rotatably connected to the outer surface of the end of the threaded rod 33 away from the motor 34. The two threaded rods 33 are rotatably connected through the transmission belt 35. A movable seat 36 is threadedly connected to the threaded rod 33. A scanner 37 is fixedly installed on the upper surface of the movable seat 36. The scanner 37 is located below the mounting bracket 1. Initially, the scanner 37 is located at the end of the threaded rod 33 away from the motor 34.

[0036] The inner surfaces of both ends of the mounting bracket 1 are fixedly connected with sliding rods 38. The outer surfaces of both ends of the sliding rods 38 are symmetrically slidably fitted with sliding seats 39. The sliding seats 39 are arranged in pairs as a group, and there are two groups of sliding seats 39 symmetrically arranged. The upper surface of the sliding seats 39 and the upper surface of the center plate 31 are set to the same horizontal plane. The upper surface of the sliding seats 39 is fixedly connected with a fixing seat 310.

[0037] The fixing seat 310 is configured as a near-L shape, with the top of the fixing seat 310 inclined. A connecting rod 311 is fixedly connected through the fixing seat 310, and the connecting rod 311 fixes the fixing seats 310 in the same group.

[0038] Second embodiment: as follows Figures 1 to 8 As shown, the stabilizing mechanism 5 includes a deformation groove 51, which is formed through the side surface of the fixed base 310. The top and bottom surfaces of the fixed base 310 are set as arc surfaces. An expansion bladder 52 is fixedly fitted inside the deformation groove 51. Closing plates 53 are symmetrically arranged on both sides of the deformation groove 51. The top of the closing plates 53 is fixedly connected to the side surface of the fixed base 310.

[0039] A pressure plate 54 is slidably sleeved on the outer surface of the threaded rod 33. The pressure plate 54 is located on the side of the movable seat 36 near the motor 34. A spring 55 is fixedly connected to the surface of the pressure plate 54 away from the movable seat 36. The spring 55 is sleeved on the outer side of the threaded rod 33. The end of the spring 55 away from the pressure plate 54 is fixedly connected to the inner surface of the mounting plate 32.

[0040] A compression bladder 56 is fixedly connected to the surface of the movable seat 36 near the pressure plate 54. The surface of the compression bladder 56 away from the movable seat 36 is fixedly connected to the inner surface of the pressure plate 54. A limiting plate 57 is fixedly connected to the side surface of the movable seat 36. The end of the limiting plate 57 away from the movable seat 36 is slidably connected to the pressure plate 54. The internal cavity of the compression bladder 56 is connected to the expansion bladder 52 through a hose.

[0041] The upper surface of the mounting bracket 1 is provided with a mounting groove 58. The inner surface of the mounting groove 58 is rotatably connected to a rotating shaft 59. The outer surface of the rotating shaft 59 is fixedly sleeved with a sleeve 510. The outer surface of the sleeve 510 is fixedly connected with a deformation bladder 511. The outer surfaces of both ends of the sleeve 510 are symmetrically fixedly connected with limit rings 512. The limit rings 512 are located on both sides of the deformation bladder 511. The outer surface of the deformation bladder 511 is fixedly connected with a bonding plate 513. The side surface of the bonding plate 513 away from the deformation bladder 511 is fixedly connected with a connecting plate 514. The end of the connecting plate 514 away from the bonding plate 513 is fixedly connected with a support plate 515. The outer surface of the support plate 515 is fixedly connected with a rubber plate 516. The outer surface of the rubber plate 516 is attached to the bottom surface of the sliding seat 39. The two ends of the rubber plate 516 are symmetrically fixedly connected with connecting strips 517. The wall thickness of the middle part of the connecting strip 517 is smaller than that of the two sides.

[0042] A connecting pipe 518 is fixedly connected through the connecting plate 514. The two ends of the connecting pipe 518 are elastically slidably inserted with plug rods 519. The connecting pipe 518 and the plug rods 519 are combined into a ring shape. The inside of the rotating shaft 59 is hollow. The internal cavity of the deformation bladder 511 is connected to the internal cavity of the rotating shaft 59. A connecting groove 520 is opened on the upper surface of the mounting bracket 1. The connecting groove 520 is connected to the internal cavity of the rotating shaft 59. The connecting groove 520 is also connected to the internal cavity of the compression bladder 56 through a hose.

[0043] During operation, pulling one of the connecting rods 311 will move a set of fixed seats 310 outward along the slide bar 38 via the sliding seat 39 at its bottom, increasing the distance between the two sets of fixed seats 310. At this time, the aluminum profile sheet to be measured can be placed horizontally on the center plate 31. Then, releasing the pulling of the connecting rod 311 will cause the fixed seats 310 to return to their original position along the slide bar 38 under the action of the elastic force. Finally, the two sets of fixed seats 310 clamp and fix the sheet. At this time, the motor 34 is started. After the motor 34 starts, it drives the threaded rod 33 to rotate. When the threaded rod 33 rotates, it drives the moving seat 36 to move horizontally towards the side of the motor 34 through the thread. Then, the scanner 37 on the top of the moving seat 36 completes the scanning and measurement of the sheet. When the sheet metal is fixed, the pulled fixing seat 310 automatically resets initially, causing the two sets of fixing seats 310 to press against both sides of the sheet metal. At this time, the two sets of fixing seats 310 automatically balance under the action of elastic force, thereby ensuring that the sheet metal is always in the center position of the mounting frame 1. This not only improves the subsequent measurement accuracy, but also allows the equipment to automatically adapt to aluminum profiles of various widths, greatly improving the applicability of the equipment. Furthermore, when the fixing seat 310 presses against both sides of the sheet metal, the deformation groove 51 set on the top of the fixing seat 310 causes the inner surface of the top of the fixing seat 310 to be in an elastic deformation state, so that the clamping thickness of the fixing seat 310 is in a variable state. This allows the equipment to automatically match sheet metal of various thicknesses and dimensions. This further enhances the applicability of the equipment. After the top of the fixed seat 310 deforms, it will always press against both sides of the plate under the action of elasticity, thus completing the self-adaptive fixation. This greatly reduces the cumbersomeness of fixation and improves measurement efficiency. After the plate is automatically clamped and fixed, the moving seat 36 will gradually move closer to the pressure plate 54 as it moves. At this time, the pressure plate 54 is initially stationary due to the support of the spring 55. That is, the moving seat 36 begins to squeeze the compression bladder 56. When the compression bladder 56 is squeezed and deformed, it moves synchronously towards the motor 34 along with the pressure plate 54. When the compression bladder 56 is squeezed, it will transfer the air pressure inside to the expansion bladder 52 in the fixed seat 310, thereby increasing the air pressure in the expansion bladder 52 and causing the fixed seat to... The bottom surface of 310 expands downwards and finally presses firmly against the upper surface of the plate, thereby maintaining the stability of the plate during measurement and avoiding measurement accuracy problems caused by different levels of vibration between the plate and the scanner 37 due to mechanical vibration during measurement. When the compression bladder 56 is compressed, it simultaneously delivers its internal air pressure to the connecting groove 520 on the mounting bracket 1, causing the air pressure in the connecting groove 520 to increase. This, in turn, increases the air pressure inside the rotating shaft 59 connected to it, thus increasing the air pressure inside the deformation bladder 511 connected to it on the outside of the sleeve 510. This causes the bonding plate 513 to begin moving outwards, causing the bonding plate 513 to expand outwards. Ultimately, this causes the support plate 515 connected by the connecting plate 514 to expand outwards.Even if the rubber plate 516 on the outer side of the support plate 515 exerts a compressive force on the lower surface of the sliding seat 39, it ensures air pressure support for the bottom of the sliding seat 39 during measurement. Combined with the expansion bladder 52, this provides enhanced air pressure fixation to the upper and lower sides of the plate, further preventing measurement accuracy issues caused by vibrations at different frequencies between the plate and the scanner 37. Simultaneously, the initial combination of the ring-shaped rubber plate 516 significantly reduces the frictional resistance of the sliding seat 39 during left and right movements, allowing the fixing seat 310 to better secure the plate. This avoids the problem of different clamping forces between the two sets of fixing seats 310 due to the frictional resistance of the sliding seat 39, which could affect the fixing effect.
