Description

Technical Field

[0001] This utility model relates to the technical field of defect monitoring, and in particular to an online defect monitoring mechanism for precision copper casting and rolling. Background Technology

[0002] In modern metallurgical industry, copper, as a crucial basic material, is widely used in various fields such as power, electronics, construction, and transportation. With increasingly stringent performance requirements for copper, ensuring its internal quality has become a critical aspect of the production process. Particularly in copper casting and rolling processes, defects such as porosity, cracks, and inclusions that may arise within the material directly affect the mechanical properties and service life of the final product. Therefore, real-time online monitoring of internal defects in copper is of great significance for improving product quality and reducing scrap rates.

[0003] Traditional offline non-destructive testing (NDT) typically requires removing samples from the production line for individual testing, which is not only time-consuming and labor-intensive but also fails to provide real-time monitoring of the entire production process. This intermittent testing method is prone to missing potential defects, leading to defective products entering the market and increasing subsequent processing costs and the risk of customer complaints. Furthermore, offline testing often requires specialized operators and equipment, increasing production costs and management complexity. Utility Model Content

Detailed Implementation

[0046] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figures 1 to 6 As shown, this embodiment provides a precision copper casting and rolling online defect monitoring mechanism, including:

[0049] Two fixing parts 1 are provided with two shaft holes. The two fixing parts 1 are respectively set on the supports on both sides of the casting and rolling equipment, serving as the basic installation platform for the entire monitoring mechanism.

[0050] Two threaded rods 2 are rotatably installed in the threaded holes of two fixing parts 1 respectively;

[0051] The movable part 3 is slidably connected to two threaded rods 2 respectively, and a transmission part 4 is slidably installed inside the movable part 3. The transmission part 4 has threaded grooves at both ends symmetrically, and the threaded grooves are respectively configured to cooperate with the threaded rods 2.

[0052] The drive mechanism 5 is mounted on a fixed part 1 and is connected to two threaded rods 2 to provide power.

[0053] The support mechanism 6 is mounted on the movable part 3, and the support mechanism 6 is equipped with an ultrasonic transmitting module 7 and an ultrasonic receiving module 8 for non-destructive testing of internal defects in copper materials.

[0054] Adjustment mechanism 9 is installed on two fixed parts 1. Adjustment mechanism 9 is connected to transmission part 4. Adjustment mechanism 9 is used to drive transmission part 4 to switch the connection with two threaded rods 2 so as to adjust the moving direction of moving part 3.

[0055] In this embodiment, two fixed components 1 serve as the basic installation platform, firmly set on the supports on both sides of the casting and rolling equipment, providing reliable support for the entire monitoring mechanism. The cooperation between the threaded rod 2, the moving component 3, and the transmission component 4 converts the rotation of the threaded rod 2 into the linear motion of the moving component 3, realizing the movement and detection of the monitoring component along the copper casting and rolling direction. The drive mechanism 5 provides power to the two threaded rods 2, ensuring the smooth and continuous operation of the moving component 3, enabling uninterrupted online monitoring of the copper. The support mechanism 6 is equipped with an ultrasonic transmitting module 7 and an ultrasonic receiving module 8, which can efficiently and accurately perform non-destructive testing on internal defects of the copper. The linkage design between the adjustment mechanism 9 and the transmission component 4 is particularly crucial. By switching the connection between the drive transmission component 4 and the two threaded rods 2, the movement direction of the moving component 3 can be flexibly changed, allowing the monitoring mechanism to perform long-distance tracking and detection along the copper's forward direction, as well as to perform focused detection by reciprocating movement in specific areas. This effectively compensates for the limitations of single-direction detection, significantly improves the monitoring coverage and detection efficiency, and ensures the timely and comprehensive detection of internal defects in the copper casting and rolling process, providing strong support for ensuring the quality of copper products.

[0056] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the adjustment mechanism 9 includes:

[0057] The drive shaft 91 is rotatably mounted in the through hole of the movable part 3, and an eccentric block 92 is mounted on the drive shaft 91;

[0058] The transmission component 93 is slidably installed inside the slot cavity of the transmission component 4, and the eccentric block 92 is slidably connected to the slot hole of the transmission component 93.

[0059] Two springs 94 are respectively installed at both ends of the conductor 93, and the other end of the spring 94 is installed inside the slot cavity of the transmission component 4;

[0060] The power mechanism 95 is mounted on two fixing parts 1 and is used to provide rotational power to the drive shaft 91.

[0061] In this embodiment, the drive shaft 91 is rotatably mounted in the through hole of the movable part 3. When the eccentric block 92 on it rotates with the drive shaft 91, it converts the rotational motion into linear motion of the movable part 93 in the slot cavity of the transmission part 4 through sliding engagement with the slot hole of the transmission part 93. Then, the transmission part 4 is driven to move by the spring 94 to switch the connection with the two threaded rods 2. The spring 94 is set to buffer the collision when the transmission part 4 contacts the threaded rod 2, providing protection for the device. The power mechanism 95 provides stable rotational power to the drive shaft 91 and can accurately control the switching timing and frequency of the transmission part 93 according to the detection requirements. When the transmission part 4 is engaged with one threaded rod 2, the movable part 3 is driven to move along the direction of the threaded rod 2. When switching to the other side, the direction of movement is changed, realizing the reciprocating movement detection of the monitoring mechanism during the copper casting and rolling process, which significantly improves the coverage and detection efficiency of online monitoring.

[0062] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the power mechanism 95 includes:

[0063] Support member 95a is mounted on movable member 3, and hollow shaft 95b is rotatably mounted on support member 95a;

[0064] Worm gear 95c is coaxially mounted on hollow shaft 95b;

[0065] Worm gear 95d is coaxially mounted on drive shaft 91, and worm gear 95d is meshed with worm 95c.

[0066] The power shaft 95e is rotatably mounted on two fixed parts 1, and the power shaft 95e is connected to the through cavity of the hollow shaft 95b. The hollow shaft 95b rotates synchronously with the power shaft 95e, and the hollow shaft 95b is slidably arranged along the length direction of the power shaft 95e.

[0067] Servo motor 95f is mounted on a fixing part 1, and the power shaft 95e is coaxially mounted with the output end of servo motor 95f;

[0068] The servo motor 95f drives the drive shaft 91 to rotate 180° in a single start by meshing the worm gear 95c and the worm wheel 95d.

[0069] In this embodiment, the support member 95a is installed on the moving member 3 to provide stable support for the hollow shaft 95b, ensuring the transmission stability when the worm 95c and worm wheel 95d mesh. The meshing structure of the worm 95c and worm wheel 95d, utilizing its large transmission ratio, smooth operation, and self-locking characteristics, accurately transmits the rotation of the hollow shaft 95b to the drive shaft 91, ensuring the accuracy of each rotation angle of the drive shaft 91. The sliding fit design between the power shaft 95e and the hollow shaft 95b allows the hollow shaft 95b to both rotate synchronously with the power shaft 95e and slide along the length of the power shaft 95e. During the movement of the moving member 3, the worm 95c and worm wheel 95d adaptively adjust their meshing. The meshing position of 5d avoids transmission failure due to displacement of moving part 3. The servo motor 95f is coaxially mounted with the power shaft 95e. Its single start can accurately drive the drive shaft 91 to rotate 180°. By controlling the rotation angle of the drive shaft 91, the eccentric block 92 is precisely driven to drive the transmission part 93 to switch the connection state between the transmission part 4 and the threaded rods 2 on both sides, realizing the automatic switching of the moving direction of the moving part 3. Through the combination of mechanical transmission and servo control, this power mechanism 95 enables the ultrasonic transmitting module 7 and the ultrasonic receiving module 8 to accurately cover the detection area during the online monitoring of copper casting and rolling, significantly improving the automation level, detection efficiency and coverage accuracy of defect detection.

[0070] As a preferred embodiment of the above technical solution, such as Figures 1 to 6 As shown, the support mechanism 6 includes:

[0071] The guide member 61 is mounted on the movable member 3, and two transmission beams 62 are slidably mounted on the guide member 61. The adjacent ends of the two transmission beams 62 are respectively provided with teeth.

[0072] Two extension pieces 63 are slidably installed in the inner holes of two transmission beams 62, and the ultrasonic transmitting module 7 and the ultrasonic receiving module 8 are respectively installed on the two extension pieces 63.

[0073] Two screws 64 are respectively installed on the two transmission beams 62. The screws 64 are used to fix the position of the extension 63 and the transmission beam 62.

[0074] The transmission mechanism 65 is mounted on the guide 61 and is used to adjust the distance between the ultrasonic transmitting module 7 and the ultrasonic receiving module 8.

[0075] In this embodiment, the guide member 61 is securely installed on the moving member 3, providing precise sliding guidance for the transmission beam 62. This ensures that the two transmission beams 62 move smoothly along a preset direction, avoiding deviation. The toothed design at the adjacent ends of the transmission beams 62, in conjunction with the transmission mechanism 65, enables synchronous reverse sliding of the two, thereby driving precise adjustment of the distance between the ultrasonic transmitting module 7 and the ultrasonic receiving module 8 installed on the extension member 63. This adapts to the testing requirements of copper materials of different specifications. The sliding setting of the extension member 63 within the inner hole of the transmission beam 62 facilitates fine-tuning of the installation position of the ultrasonic module according to the actual testing position, ensuring the effectiveness of the testing signal. The screw 64 can quickly lock the extension member 63 and the transmission beam 62, providing a reliable fixing effect after adjustment to the appropriate position, preventing displacement of the ultrasonic module during testing and affecting the testing accuracy. The transmission mechanism 65 provides stable power for the distance adjustment, enabling fine control of the distance between the ultrasonic transmitting module 7 and the ultrasonic receiving module 8, ensuring that they are always at the optimal testing distance, effectively improving the accuracy and reliability of online defect monitoring in precision copper casting and rolling.

[0076] As a preferred embodiment of the above technical solution, such as Figures 1 to 6 As shown, the transmission mechanism 65 includes;

[0077] The adjusting shaft 65a is rotatably connected to the moving part 3 and the guide part 61 respectively. The transmission gear 65b is coaxially mounted on the adjusting shaft 65a, and the transmission gear 65b is meshed with the teeth on the two transmission beams 62.

[0078] Bolt 65c passes through the shaft hole of adjusting shaft 65a and is connected to the moving part 3;

[0079] In this embodiment, the adjusting shaft 65a is rotatably connected to the moving part 3 and the guide part 61. The transmission gear 65b, coaxially mounted on the adjusting shaft 65a, meshes with the teeth on the two transmission beams 62. When the adjusting shaft 65a is rotated, the transmission gear 65b drives the two transmission beams 62 to slide synchronously in opposite directions along the guide part 61, ensuring the efficiency of the spacing adjustment between the ultrasonic transmitting module 7 and the ultrasonic receiving module 8. The bolt 65c passes through the shaft hole of the adjusting shaft 65a and is connected to the moving part 3. After the appropriate spacing is adjusted, the adjusting shaft 65a can be firmly locked to prevent the adjusting shaft 65a from rotating due to vibration or other factors during the detection process, thus ensuring the stability of the ultrasonic module spacing and ensuring the consistency and accuracy of the detection signal.

[0080] As a preferred embodiment of the above technical solution, such as Figures 1 to 2 As shown, the drive mechanism 5 includes:

[0081] Two auxiliary shafts 51 are rotatably mounted on a fixed part 1, and the two auxiliary shafts 51 are parallel to the rotation axis of the two threaded rods 2;

[0082] Two drive gears 52 are coaxially mounted on two auxiliary shafts 51, and the two drive gears 52 are meshed together.

[0083] Two driven gears 53 are coaxially mounted on two threaded rods 2, and two driving gears 52 are respectively meshed with two driven gears 53;

[0084] The drive motor 54 is mounted on a fixed part 1, and the output end of the drive motor 54 is coaxially mounted with an auxiliary shaft 51.

[0085] An isolator 55 is installed on the fixing member 1, and the two driving gears 52 and the two driven gears 53 are respectively located inside the isolator 55;

[0086] In this embodiment, the drive mechanism 5 is designed to achieve synchronous counter-rotation of the two threaded rods 2. This structure can be replaced by a sprocket and chain structure or a transmission belt structure.
