Description

Technical Field

[0001] This utility model relates to the field of precision measurement technology, specifically to an online rapid testing device for cylinders. Background Technology

[0002] In the fabrication process of silicon carbide particle-reinforced aluminum matrix composite shells, near-net-shape cylindrical components have requirements for the precise control of circumferential rib dimensions. The technical specifications clearly stipulate that the dimensional deviation of the circumferential ribs should not exceed 10%. These cylindrical components can reach several meters in length and are large-size structural parts. The height, width, and spacing of their circumferential ribs need to be precisely measured along the entire circumference after processing to ensure that they meet the requirements of high-end equipment such as underwater vehicles.

[0003] In traditional inspection methods, when using calipers or templates for measurement, manual point-by-point measurement is required, which is not only extremely inefficient, but also highly susceptible to human error, making it difficult to achieve comprehensive inspection of the entire circumference. Although coordinate measuring machines (CMMs) offer high measurement accuracy, they are bulky and complex to operate, making them unsuitable for online use on the production site. This fails to meet the real-time inspection needs of cylindrical components after processing, severely impacting production efficiency and product quality control progress.

[0004] To address the shortcomings of the existing technology, there is an urgent need for an online detection device that can adapt to large-sized cylinders, quickly achieve circumferential and axial movement, and accurately measure the dimensions of the rib rings in real time. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems by providing an online rapid inspection device for cylinders. This device solves the installation and adaptation difficulties of inspection devices for large-size cylinders by using an annular guide rail base composed of two detachable and interlocking semicircular guide rails. The measuring sliding unit automatically slides along the guide rail under drive, causing the inspection unit to scan the entire circumference of the cylinder and communicate with the terminal processing unit in real time. This design achieves efficient and automated online inspection of the circumferential rib dimensions of large-size cylinders, significantly improving inspection efficiency and accuracy.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An online rapid inspection device for cylinders includes a support frame, an annular guide rail base, a measuring sliding unit, and a detection unit. The annular guide rail base is formed by two semicircular guide rails mating together. The two semicircular guide rails are respectively mounted on an independent support frame and can be mated or separated from each other. A measuring sliding unit is slidably fitted on each semicircular guide rail. The measuring sliding unit slides along the semicircular guide rail under the drive of a measuring drive unit. The measuring sliding unit is equipped with a detection unit for performing inspection operations. The detection unit is signal-connected to a terminal processing unit, and the measuring drive unit is signal-connected to and controlled by the terminal processing unit.

[0008] Thanks to the aforementioned technical solution, the device can be adapted to large-sized cylindrical components through the annular guide rail base formed by the mating of two semicircular guide rails. The two semicircular guide rails can be mated or separated, facilitating installation and adjustment. The measuring sliding unit, which is slidably fitted on each semicircular guide rail, slides along the guide rail under the drive of the measuring drive unit, driving the detection unit to perform detection operations, thus achieving rapid scanning detection of the entire circumference of the cylinder. The detection unit signal is connected to the terminal processing unit, and the measuring drive unit is controlled by the terminal processing unit, realizing automated control and real-time data processing, thereby improving detection efficiency, reducing human error, and meeting the needs of online rapid detection.

[0009] Furthermore, the measurement drive unit includes an arc-shaped rack that matches the semi-circular guide rail, a measurement drive motor, and a measurement drive gear. The measurement drive motor is located in the measurement sliding unit, and the output shaft of the measurement drive motor is connected to the measurement drive gear. The measurement drive gear meshes with the arc-shaped rack.

[0010] Thanks to the above technical solution, the measurement drive unit drives the measurement sliding unit to slide smoothly along the semi-circular guide rail through the meshing transmission between the arc-shaped rack and the measurement drive gear. This driving method provides precise displacement control, ensuring that the detection unit moves accurately in the circumferential position of the cylinder, thereby achieving accurate measurement of the ring rib size.

[0011] Furthermore, the semicircular guide rail is an arc-shaped ball groove that can accommodate a rolling ball. The side of the arc-shaped ball groove facing the inner ring of the semicircular guide rail is an open side, and an auxiliary guide rail parallel to the arc-shaped ball groove is provided on the side wall of the open side. The measuring sliding unit includes a rolling ball and a connecting base. The diameter of the rolling ball matches the groove diameter of the arc-shaped ball groove. One end of the connecting base is provided with an arc-shaped covering groove adapted to the rolling ball, and the other end is provided with a mounting platform. The covering groove is in rolling connection with the rolling ball. The detection unit is mounted on the mounting platform. The side wall of the connecting base is provided with a limiting rolling ball that matches the auxiliary guide rail.

[0012] Thanks to the aforementioned technical solution, the semicircular guide rail features an arc-shaped ball groove design, which, together with the rolling ball and the arc-shaped covering groove of the connecting base, forms a low-friction rolling connection. This allows the measuring sliding unit to slide smoothly along the guide rail, reducing motion resistance. The auxiliary guide rail and limiting rolling ball enhance the stability of the sliding unit, prevent lateral displacement, ensure the stability of the detection unit during movement, and avoid friction between the connecting base and the semicircular guide rail. This structure improves the accuracy and reliability of the device and is suitable for long-term detection operations on large-sized cylinders.

[0013] Furthermore, the arc-shaped covering groove covers both sides of the rolling ball in the direction of travel, and the covering angle of the arc-shaped covering groove is not less than 240 degrees and less than 350 degrees.

[0014] By adopting the above technical solution, the arc-shaped covering groove covers both sides of the rolling ball in the direction of travel, and the covering angle of the arc-shaped covering groove is not less than 240 degrees and less than 350 degrees. This design not only ensures effective contact between the rolling ball and the covering groove, but also provides sufficient support and guidance; thus, while ensuring smooth sliding, it maintains the flexibility of movement and extends the service life.

[0015] Furthermore, the arc-shaped rack is located on the outside of the arc-shaped spherical groove, the arc-shaped rack and the arc-shaped spherical groove are concentrically arranged, and the measuring drive motor is assembled on the connecting base.

[0016] By adopting the above technical solution, the arc-shaped rack is located on the outside of the arc-shaped ball groove and is concentric with the arc-shaped ball groove, which makes the transmission of driving force more direct and uniform, reduces torque and vibration, and ensures the accuracy and synchronization of the sliding unit on the guide rail.

[0017] Furthermore, the detection unit is configured as at least one of a laser sensor, an ultrasonic sensor, a microwave sensor, a thermal imager, or a vision sensor.

[0018] Thanks to the above-mentioned technical solutions, the detection unit can select different types of sensors, such as laser sensors, ultrasonic sensors, microwave sensors, thermal imagers, or vision sensors, according to the detection requirements, thereby realizing the detection of multiple parameters such as the size of the cylinder ring ribs, surface defects, or temperature distribution. This flexibility allows the device to adapt to cylinder components made of different materials and processes, improving the comprehensiveness and applicability of the detection. At the same time, the sensor signals are connected to the terminal processing unit to realize real-time data processing and analysis, meeting the requirements of online rapid detection.

[0019] Furthermore, the ends of the two semicircular guide rails are provided with docking areas, which are docking blocks extending circumferentially from the ends. The docking blocks at the ends of the two semicircular guide rails are arranged opposite each other and can be engaged with each other. The docking blocks are provided with docking holes, and connectors can be assembled in the docking holes.

[0020] Thanks to the above technical solution, the two semicircular guide rails are connected by mating areas at their ends. The design of the mating block ensures the stability and concentricity of the annular guide rail base after mating. Connectors are assembled inside the mating holes, allowing the two semicircular guide rails to be quickly fastened or separated, facilitating the installation and disassembly of the device.

[0021] Furthermore, it also includes a cylinder clamping unit for clamping the cylinder component to be tested, with two support frames corresponding to the two semi-circular guide rails respectively located on both sides of the cylinder clamping unit in the width direction.

[0022] Thanks to the above technical solution, the cylinder clamping unit can be securely clamped, and the two support frames are set on both sides of the cylinder clamping unit in the width direction, so that the annular guide rail base can be arranged around the cylinder, which facilitates the detection unit to scan the entire circumference of the cylinder. This layout optimizes the detection space and realizes online rapid detection of cylinder components.

[0023] Furthermore, the bottom of the support frame is provided with a moving drive unit that can drive the support frame to move in a preset direction.

[0024] Thanks to the aforementioned technical solution, the movable drive unit at the bottom of the support frame can move the entire machine along the cylinder axis, thereby flexibly adjusting the detection position and enabling the detection of ribs at different locations. This axial movement function expands the detection range, allowing for full-length detection without moving the cylinder, which not only improves detection efficiency and ease of operation but is also particularly suitable for large, difficult-to-move cylinders.

[0025] Furthermore, the cylinder clamping unit is provided with movable guide rails on both sides in the width direction. The movable guide rails are parallel to the axis of the cylinder clamping unit. The movable drive unit is matched with the movable guide rails and can move along the movable guide rails.

[0026] Thanks to the above technical solution, the axial parallel arrangement of the moving guide rail and the cylinder clamping unit provides precise guidance for the movement of the support frame, ensuring straightness and stability during the movement. The matching of the moving drive unit and the moving guide rail enables the support frame to move smoothly and accurately along the axial direction, thereby driving the detection unit to scan different axial positions of the cylinder. This design realizes the device's dual-degree-of-freedom movement in both the circumferential and axial directions, fully covering the cylinder surface and meeting the requirements for accurate detection across the entire circumference and length.

[0027] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: the annular guide rail base is formed by two semi-circular guide rails that can be joined together or separated, enabling the device to quickly adapt to large-sized cylindrical components and facilitate installation and adjustment; the measuring sliding unit, which is slidably fitted on each semi-circular guide rail, slides along the guide rail under the drive of the measuring drive unit, driving the detection unit to perform detection operations, realizing rapid and automated scanning detection of the entire circumference of the cylinder; the detection unit signal is connected to the terminal processing unit, and the measuring drive unit is controlled by the terminal processing unit, realizing real-time data acquisition and processing, thereby greatly improving detection efficiency, reducing human error, and meeting the online accurate and rapid detection requirements of cylindrical components after processing.

Detailed Implementation

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] Example 1

[0037] A rapid online inspection device for cylinders, such as Figures 1-5 As shown, the device includes a support frame 10, an annular guide rail base 20, a measuring sliding unit 30, and a detection unit 40. The annular guide rail base 20 is formed by two semicircular guide rails 21 mating together. The two semicircular guide rails 21 are respectively mounted on an independent support frame 10, and the two semicircular guide rails 21 can be mated together or separated from each other. A measuring sliding unit 30 is slidably fitted on each semicircular guide rail 21. The measuring sliding unit 30 slides along the semicircular guide rail 21 under the drive of the measuring drive unit. The measuring sliding unit 30 is equipped with a detection unit 40 for performing detection operations. The detection unit 40 is signal-connected to the terminal processing unit, and the measuring drive unit is signal-connected to and controlled by the terminal processing unit. Specifically, the annular guide rail base 20 formed by the engagement of two semicircular guide rails 21 allows the device to adapt to large-sized cylindrical components. The two semicircular guide rails 21 can be engaged or disengaged, facilitating installation and adjustment. The measuring sliding unit 30, slidably fitted on each semicircular guide rail 21, slides along the guide rail under the drive of the measuring drive unit, driving the detection unit 40 to perform detection operations, achieving rapid scanning detection of the entire circumference of the cylinder. The detection unit 40 is signal-connected to the terminal processing unit, and the measuring drive unit is controlled by the terminal processing unit, realizing automated control and real-time data processing, thereby improving detection efficiency, reducing human error, and meeting the needs of online rapid detection. Understandably, when the device is in operation, the two support frames 10 bearing the semicircular guide rails 21 are first placed on both sides of the cylinder to be inspected (such as a large-sized silicon carbide particle-reinforced aluminum matrix composite cylindrical component), and then the two semicircular guide rails 21 are engaged and connected above or to the side of the cylinder to form a complete annular track. The terminal processing unit starts up and controls the measurement drive unit to work, driving the two measurement sliding units 30 to slide synchronously or asynchronously along the semi-circular guide rail 21 from the initial position. The detection unit 40 on it continuously scans and measures the height, width or surface condition of the ring ribs on the outer wall of the cylinder as required, and transmits the data back to the terminal processing unit in real time for processing and analysis, and finally generates a detection report.

[0038] The measurement drive unit includes an arc-shaped rack 331 matched with the semi-circular guide rail 21, a measurement drive motor, and a measurement drive gear 333. The measurement drive motor is located on the measurement sliding unit 30, and its output shaft is connected to the measurement drive gear 333. The measurement drive gear 333 meshes with the arc-shaped rack 331. Specifically, the measurement drive unit drives the measurement sliding unit 30 to slide smoothly along the semi-circular guide rail 21 through the meshing transmission of the arc-shaped rack 331 and the measurement drive gear 333. This driving method provides precise displacement control, ensuring that the detection unit 40 moves accurately in the circumferential position of the cylinder, thereby achieving accurate measurement of the ring rib size. It can be understood that when the measurement drive motor receives a command from the terminal processing unit, its output shaft drives the measurement drive gear 333 to rotate. Since the measurement drive gear 333 meshes with the arc-shaped rack 331 fixedly installed on the semi-circular guide rail 21, the force generated by the rotation of the gear will act on the measurement sliding unit 30, pushing it to slide along the semi-circular guide rail 21 concentric with the rack. By controlling the speed and direction of the motor, the moving speed and position of the measuring sliding unit 30 can be precisely controlled. In other embodiments, the measuring drive unit can also be driven by friction wheels, linear motors, or synchronous belts. For example, a smooth arc-shaped friction surface can be provided on the side of the semi-circular guide rail 21, and the motor on the measuring sliding unit 30 drives the friction wheel to press against the friction surface for driving.

[0039] The semicircular guide rail 21 is an arc-shaped ball groove 212 that can accommodate a rolling ball 31. The side of the arc-shaped ball groove 212 facing the inner ring of the semicircular guide rail 21 is an open side. An auxiliary guide rail 213 parallel to the arc-shaped ball groove 212 is provided on the side wall of the open side. The measuring sliding unit 30 includes a rolling ball 31 and a connecting base 32. The diameter of the rolling ball 31 matches the groove diameter of the arc-shaped ball groove 212. One end of the connecting base 32 is provided with an arc-shaped covering groove 321 adapted to the rolling ball 31, and the other end is provided with a mounting platform 322. The covering groove is tumblingly connected to the rolling ball 31. The detection unit 40 is mounted on the mounting platform 322. The side wall of the connecting base 32 is provided with a limiting rolling ball 332 that can match the auxiliary guide rail 213. Specifically, the semicircular guide rail 21 adopts an arc-shaped ball groove 212 design, which, together with the rolling balls 31 and the arc-shaped covering groove 321 of the connecting base 32, forms a low-friction rolling connection, allowing the measuring sliding unit 30 to slide smoothly along the guide rail and reducing motion resistance. The auxiliary guide rail 213 and the limiting rolling ball 332 enhance the stability of the sliding unit, prevent lateral displacement, ensure the stable posture of the detection unit 40 during movement, and avoid friction between the connecting base 32 and the semicircular guide rail 21. This structure improves the accuracy and reliability of the device and is suitable for long-term detection operations on large-size cylinders. It can be understood that the arc-shaped ball groove 212 provides a pre-set rolling track for multiple rolling balls 31, and the connecting base 32 "rides" on the rolling balls 31 through its arc-shaped covering groove 321. When the drive unit pulls the connecting base 32, relative rolling occurs between the connecting base 32 and the rolling balls 31, thereby driving the entire sliding unit to move along the ball groove. This is a highly efficient, heavy-duty, low-friction kinematic pair. The auxiliary guide rail 213 on the side cooperates with the limiting ball 332 to mainly bear the possible radial load, prevent the connecting base 32 from coming off the side or twisting, and ensure the accuracy of the motion trajectory.

[0040] The arc-shaped covering groove 321 covers both sides of the rolling ball 31 in the direction of travel, and the covering angle of the arc-shaped covering groove 321 is not less than 240 degrees and less than 350 degrees. Specifically, the arc-shaped covering groove 321 covers both sides of the rolling ball 31 in the direction of travel, and the covering angle of the arc-shaped covering groove 321 is 280 degrees. This design ensures effective contact between the rolling ball 31 and the covering groove, providing sufficient support and guidance; thus, while ensuring smooth sliding, it maintains the flexibility of movement and extends the service life. It can be understood that the covering angle refers to the central angle corresponding to the arc-shaped covering groove 321. The large covering angle of 280 degrees means that the connecting base 32 wraps around the rolling ball 31 from above and both sides, providing a large contact area and constraint. This makes the contact stress distribution more uniform when the rolling ball 31 bears the vertical load and lateral load from the connecting base 32 and the detection unit 40, and it is less prone to local wear or jamming. Meanwhile, the rolling ball 31 can still roll smoothly within the covering groove, ensuring low resistance and flexibility of movement. This large covering angle design is particularly suitable for industrial inspection scenarios that require high stability and long lifespan.

[0041] The arc-shaped rack 331 is disposed on the outside of the arc-shaped ball groove 212, and the arc-shaped rack 331 and the arc-shaped ball groove 212 are concentrically arranged. The measuring drive motor is mounted on the connecting base 32. Specifically, the arc-shaped rack 331 is disposed on the outside of the arc-shaped ball groove 212 and is concentric with the arc-shaped ball groove 212, which makes the transmission of driving force more direct and uniform, reduces torque and vibration, and ensures the accuracy and synchronization of the sliding of the measuring sliding unit 30 on the guide rail. It can be understood that the concentric arrangement ensures that the driving trajectory is completely consistent with the movement trajectory of the rolling ball 31, avoiding additional stress or slippage caused by trajectory misalignment.

[0042] The detection unit 40 is configured with at least one of a laser sensor, an ultrasonic sensor, a microwave sensor, a thermal imager, or a vision sensor. In this embodiment, a laser sensor is used. Specifically, the detection unit 40 can select different types of sensors, such as laser sensors, ultrasonic sensors, microwave sensors, thermal imagers, or vision sensors, according to the detection requirements, thereby achieving multi-parameter detection of cylinder ring rib dimensions, surface defects, or temperature distribution. This flexibility allows the device to adapt to cylinder components made of different materials and processes, improving the comprehensiveness and applicability of the detection. Simultaneously, the sensor signals are connected to the terminal processing unit to achieve real-time data processing and analysis, meeting the requirements of online rapid detection. It is understood that the installed sensors can be flexibly changed for different detection purposes. For example, a laser displacement sensor can be used to measure the contour dimensions of the ring ribs non-contactly and with high precision; an ultrasonic sensor can be used to detect cylinder wall thickness or internal defects; a vision sensor (industrial camera) combined with a light source can detect surface scratches, corrosion, and other appearance defects; and a thermal imager can be used to detect the temperature uniformity of the cylinder during the process. The terminal processing unit has built-in different processing modules that can analyze the corresponding sensor data. In other embodiments, the platform 322 may be designed as a quick-change interface to facilitate rapid switching between different functional sensor heads on the detection line.

[0043] The two semicircular guide rails 21 are provided with mating areas 211 at their ends. Each mating area 211 is a mating block extending circumferentially from its end. The mating blocks at the ends of the two semicircular guide rails 21 are arranged opposite each other and can engage. Each mating block has a mating hole 2111, into which a connector can be assembled. Specifically, the two semicircular guide rails 21 are connected by mating areas 211 at their ends. The design of the mating blocks ensures the stability and concentricity of the annular guide rail base 20 after engagement. Connectors are assembled in the mating holes 2111, allowing the two semicircular guide rails 21 to be quickly fastened or separated, facilitating the installation and disassembly of the device. The thickness of the mating block is at least half the thickness of the semicircular guide rail. It is understood that the mating block extends tangentially or chordally from the ends of the semicircular guide rails 21, increasing the area of ​​the mating surface and improving the connection rigidity. During engagement, the contact surfaces of the two mating blocks are tightly fitted and fixed by pins, bolts, or quick-locking pins inserted into the mating holes 2111. This design ensures good concentricity of the two semicircular guide rails 21, guaranteeing measurement accuracy. During disassembly, simply remove the connector to separate the two semicircular guide rails 21 to the sides.

[0044] It also includes a cylinder clamping unit (not shown in the figure) for clamping the cylinder component to be inspected. Two support frames 10 corresponding to the two semicircular guide rails 21 are respectively arranged on both sides of the cylinder clamping unit in the width direction. Specifically, the arrangement of the cylinder clamping unit allows the cylinder component to be inspected to be securely clamped; the two support frames 10 are arranged on both sides of the cylinder clamping unit in the width direction, allowing the annular guide rail base 20 to be arranged around the cylinder, facilitating the inspection unit 40 to scan the entire circumference of the cylinder; this layout optimizes the inspection space and realizes online rapid inspection of the cylinder component. It can be understood that the cylinder clamping unit can be a V-shaped support block, chuck, or clamp, etc., used to fix the cylinder during the inspection process, prevent it from rolling or moving, and ensure the stability of the inspection reference. The support frames 10 stand on both sides of the clamping unit, so that the two semicircular guide rails 21 can be fitted together on the outside of the cylinder, and the inspection unit 40 performs circumferential scanning along the annular guide rail.

[0045] The support frame 10 is equipped with a moving drive unit 11 at its bottom, which can drive the support frame 10 to move along a preset direction. Specifically, the moving drive unit 11 at the bottom of the support frame 10 can drive the entire machine to move along the cylinder axis, thereby flexibly adjusting the detection position and realizing the detection of ring ribs at different positions. This axial movement function expands the detection range, allowing for full-length detection without moving the cylinder, which not only improves detection efficiency and ease of operation, but is also particularly suitable for large-sized, difficult-to-move cylinders. It is understood that the moving drive unit 11 can be a motor-driven wheel assembly, linear module, or cylinder, etc. When it is necessary to detect ring ribs at different axial positions on the cylinder, the terminal processing unit controls the moving drive unit 11 to work, driving the support frames 10 on both sides and the entire annular guide rail detection mechanism on them to move synchronously in a direction parallel to the cylinder axis. After moving to the target position, the drive is locked or stopped, and then the perimeter scan of that section is performed. In this way, by combining axial movement and circumferential scanning, full coverage detection of a specified area or even the entire outer surface of the cylinder surface is achieved. In other embodiments, the support frame 10 may also be equipped with a lifting function to accommodate cylinders of different diameters.

[0046] The cylinder clamping unit has movable guide rails 51 on both sides in the width direction. These movable guide rails 51 are parallel to the axial direction of the cylinder clamping unit. The movable drive unit 11 is matched with the movable guide rails 51 and can move along them. Specifically, the movable guide rails 51 are arranged parallel to the axial direction of the cylinder clamping unit, providing precise guidance for the movement of the support frame 10 and ensuring straightness and stability during movement. The movable drive unit 11 matches the movable guide rails 51, enabling the support frame 10 to move smoothly and accurately along the axial direction, thereby driving the detection unit 40 to scan different axial positions of the cylinder. This design achieves dual-degree-of-freedom movement of the device in both the circumferential and axial directions, fully covering the cylinder surface and meeting the requirements for precise detection across the entire circumference and length. It is understood that the movable guide rails 51 (such as precision linear guide rails) are fixedly installed on the ground or base, and the bottom of the support frame 10 is connected to the movable guide rails 51 via casters. The movable drive unit 11 acts on the casters, driving them to move precisely along the movable guide rails 51. This structure ensures that the two support frames 10 remain synchronized and parallel during axial movement, thereby ensuring the axial position accuracy of the annular guide rail base 20 relative to the cylinder and avoiding the problem that the detection section is not perpendicular to the cylinder axis due to movement errors.
