Description

Technical Field

[0001] The present invention relates to the technical field of phosphor copper tube production detection, and in particular to a precision phosphor copper tube inner and outer wall trace detection device and a use method thereof. Background Art

[0002] Phosphor copper tubes, with their exceptional mechanical properties, good corrosion resistance, and excellent processing capabilities, play a key role in numerous high-precision manufacturing fields. In the aerospace sector, phosphor copper tubes are used to manufacture key components in aircraft hydraulic and fuel systems, and their quality is directly related to flight safety. In the refrigeration industry, phosphor copper tubes are important channels for the circulation of refrigerant in air conditioners, refrigerators, and other refrigeration equipment, and their performance affects cooling efficiency and equipment life. In the field of precision instruments, phosphor copper tubes are used to manufacture high-precision sensors and measuring instruments, which require extremely high dimensional accuracy and surface quality.

[0003] However, during the production and use of phosphor copper tubes, various marks and defects such as cracks, pores, inclusions, and scratches may appear on the inner and outer walls of the tubes due to factors such as raw material quality, processing technology, transportation, and storage. These defects not only reduce the mechanical properties and corrosion resistance of the tubes, but may also cause serious accidents such as leakage and breakage during use, resulting in significant safety hazards and economic losses. Therefore, during the production process of phosphor copper tubes, high-precision internal and external wall mark inspection is required.

[0004] At present, traditional phosphor copper tube inspection methods mainly include eddy current testing, magnetic particle testing, penetration testing and radiographic testing. However, these methods have many limitations when detecting traces on the inner and outer walls of phosphor copper tubes: Eddy current testing is mainly based on the principle of electromagnetic induction. Its detection rate for shallow surface defects (within 1.5mm from the surface) is insufficient. This is because the distribution of eddy currents on the pipe surface is affected by the skin effect. When the defect depth is shallow, the eddy current changes are not obvious and are difficult to be effectively detected. Eddy current testing cannot directly distinguish between inner and outer wall defect signals, which can easily lead to misjudgment. In actual testing, the eddy current signals generated by inner and outer wall defects will superimpose on each other, making it difficult for inspectors to accurately determine the location and nature of the defects, with a misjudgment rate of up to 15%. Eddy current testing has high requirements for pipe material and shape. It is sensitive to the physical properties of the pipe, such as electrical conductivity and magnetic permeability. Pipes of different materials and shapes require different testing parameters and probes, which increases the complexity and cost of testing.

[0005] Phosphor copper tubes are non-ferromagnetic materials, and magnetic particle testing cannot be directly applied to them. Even if the surface of phosphor copper tubes is made magnetic through special treatment, the accuracy and reliability of the test will be affected. Magnetic particle testing requires multiple steps such as magnetization, application of magnetic powder, observation, and recording. The operation process is cumbersome and the test efficiency is low, making it difficult to meet the needs of large-scale production. Magnetic particle testing requires a certain surface finish of the tube, otherwise it will affect the adhesion of magnetic powder and the display effect of defects. For phosphor copper tubes with rough surfaces, additional surface treatment is required, which increases the cost and time of testing.

[0006] Penetrant testing can only detect open defects on the surface of pipes, and cannot effectively detect internal defects and closed surface defects. During the use of phosphor copper pipes, internal defects will also have a serious impact on the performance of the pipes. Penetrant testing requires multiple steps such as penetration, cleaning, and imaging. The testing cycle is long, generally taking several hours or even days to complete the test, which cannot meet the needs of rapid testing. The penetrants and developers used in penetrant testing usually contain organic solvents and chemicals, which have certain hazards to the environment and the health of operators, and corresponding protective measures need to be taken.

[0007] Radiographic inspection equipment is expensive and has high maintenance costs, making it unaffordable for some small and medium-sized enterprises. Radiographic inspection also produces X-rays or gamma rays, which pose a certain radiation hazard to the human body. Strict radiation protection measures are required during the inspection process to ensure operator safety. While radiographic inspection can clearly display internal defects in pipes, quantitative analysis of defect size, shape, and properties is difficult and requires specialized image processing software and experienced inspectors.

[0016] Preferably, vertical limiting sliding bars are fixedly mounted on both sides of the upper end of the L-shaped mounting plate, and the upper ends of the vertical limiting sliding bars are passed through and movably connected to the side ends of the longitudinal moving platform.

[0017] A method for using a precision phosphor copper tube inner and outer wall trace detection device includes the following steps: S1. By draining water into the cleaning tank and the testing tank respectively, when the water is drained into the cleaning tank and the testing tank respectively, by placing the phosphor copper tube to be tested on the inner side of the secondary support roller and the main support roller, when the phosphor copper tube is placed on the inner side of the secondary support roller and the main support roller, the phosphor copper tube is limitedly rolled and supported by the inner side of the secondary support roller and the main support roller; S2. When the auxiliary supporting roller and the inner side of the main supporting roller provide limited rolling support for the phosphor copper tube, the lifting motor is turned on by controlling the lifting motor. When the lifting motor is turned on, the lifting screw is driven to rotate. When the lifting screw rotates, the force generated by the threaded connection drives the lifting block to move up and down in a straight line. When the lifting block moves downward in a straight line, it drives the L-shaped lifting arm to move downward in a straight line. When the L-shaped lifting arm moves downward in a straight line, the horizontal support platform moves downward in a straight line. When the horizontal support platform moves downward in a straight line, it synchronously drives the auxiliary supporting roller and the phosphor copper tube inside the main supporting roller to move downward in a straight line to the inside of the cleaning tank. S3. When the phosphor copper tube moves straight downward to the inside of the cleaning tank, the ultrasonic generator is turned on by control. When the ultrasonic generator is turned on, it will cooperate with the water in the cleaning tank to perform high-frequency vibration cleaning on the inner and outer surfaces of the phosphor copper tube, so that the dirt and impurities attached to the inner and outer surfaces of the phosphor copper tube fall off. After the inner and outer surfaces of the phosphor copper tube are cleaned by high-frequency vibration, the blower is turned on by control. When the blower is turned on, air is blown to the aeration disk through the air pipe, so that the aeration disk aerates the inside of the cleaning tank. When the aeration disk aerates the inside of the cleaning tank, it accelerates the flow of water in the cleaning tank, so that the impurities fallen off the inner and outer surfaces of the phosphor copper tube are carried away by the water flow, preventing dirt from being deposited on the inner and outer surfaces of the phosphor copper tube again, thereby improving the cleaning efficiency; S4. When the pretreatment and cleaning of the phosphor copper tube is completed, the lifting motor is controlled to be turned on synchronously to drive the phosphor copper tube to move straight upward out of the cleaning tank. When the phosphor copper tube moves straight upward out of the cleaning tank, the rotating motor is controlled to be turned on. When the rotating motor is turned on, it will synchronously drive the rotating table to rotate. When the rotating table rotates, it will drive the support rod to rotate horizontally. When the support rod rotates horizontally, it will synchronously drive the phosphor copper tube to rotate horizontally. When the phosphor copper tube rotates horizontally to just above the detection tank, the lifting motor is controlled to be turned on synchronously to drive the phosphor copper tube to move straight downward into the detection tank. S5. When the phosphor copper tube moves into the detection pool, the focusing probe is turned on through the control of the detection host. When the focusing probe is turned on, ultrasonic waves will be emitted to the phosphor copper tube. The ultrasonic waves will propagate in the water inside the detection pool. When they reach the outer surface of the phosphor copper tube, part of the energy is reflected back to the focusing probe to form a primary interface echo; the other part of the energy enters the phosphor copper tube, and when it encounters defects or the surface of the other side of the phosphor copper tube during the propagation process inside the phosphor copper tube, it is reflected back to the focusing probe again to form secondary interface echoes and other defect echoes. The echo signal received by the focusing probe is transmitted to the detection host, which amplifies, filters and digitizes the signal, and then generates a scanning signal. At the same time, according to the position information and scanning parameters of the focusing probe, the scanning signal is converted into an image for dense phosphor copper tube inner and outer wall trace detection and analysis, and the scanning parameters and detection analysis data are displayed on the display panel; S6. When the focusing probe detects traces on the inner and outer walls of the phosphor bronze tube, the waterproof motor is turned on by control. When the waterproof motor is turned on, it will synchronously drive the main transmission shaft to rotate. When the main transmission shaft rotates, it will drive the main support roller to rotate. When the main support roller rotates, it will cooperate with the auxiliary support roller to drive the phosphor bronze tube to rotate evenly. When the phosphor bronze tube rotates evenly, the first adjustment motor is turned on by control. When the first adjustment motor is turned on, it will drive the first adjustment screw to rotate. When the first adjustment screw rotates, the force generated by the threaded connection will drive the L-shaped horizontal moving seat to move horizontally and linearly. When the L-shaped horizontal moving seat moves horizontally and linearly, it will synchronously drive the focusing probe to move horizontally and linearly, so that the focusing probe can detect the phosphor bronze tube horizontally.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention controls the turning on of an ultrasonic generator when the phosphor copper tube moves linearly downward to the inside of the cleaning tank. When the ultrasonic generator is turned on, it cooperates with the water in the cleaning tank to perform high-frequency vibration cleaning on the inner and outer surfaces of the phosphor copper tube, so that the dirt and impurities attached to the inner and outer surfaces of the phosphor copper tube fall off. After the inner and outer surfaces of the phosphor copper tube are cleaned with high-frequency vibration, the blower is controlled to turn on. When the blower is turned on, air is blown to the aeration disk through the air pipe, so that the aeration disk aerates the inside of the cleaning tank. When the aeration disk aerates the inside of the cleaning tank, the flow of water in the cleaning tank is accelerated, so that the impurities fallen off the inner and outer surfaces of the phosphor copper tube are carried away by the water flow, and the dirt is prevented from being deposited on the inner and outer surfaces of the phosphor copper tube again, thereby improving the cleaning efficiency, thereby achieving the effect of pre-treatment cleaning of the phosphor copper tube, and preventing the dirt and impurities attached to the inner and outer surfaces of the phosphor copper tube from affecting the inspection effect of the inner and outer surface marks. The present invention also controls the focusing probe to be turned on by the detection host when the phosphor copper tube moves to the inside of the detection pool. When the focusing probe is turned on, ultrasonic waves are emitted to the phosphor copper tube. The ultrasonic waves propagate in the water inside the detection pool. When they reach the outer surface of the phosphor copper tube, part of the energy is reflected back to the focusing probe to form a primary interface echo. The other part of the energy enters the phosphor copper tube and, when it encounters defects or the surface of the other side of the phosphor copper tube during propagation inside the phosphor copper tube, is reflected back to the focusing probe again to form secondary interface echoes and other defect echoes. The echo signal received by the focusing probe is transmitted to the detection host, which amplifies, filters and digitally processes the signal and then generates a scanning signal. At the same time, according to the position information and scanning parameters of the focusing probe, the scanning signal is converted into an image to perform dense phosphor copper tube inner and outer wall trace detection and analysis, and the scanning parameters and detection analysis data are displayed through a display panel, thereby facilitating the detection of inner and outer wall traces of the phosphor copper tube. When the focusing probe detects inner and outer wall traces on the phosphor copper tube, the present invention controls to start the waterproof motor. When the waterproof motor is turned on, it drives the first transmission gear to rotate. When the first transmission gear rotates, it engages and drives the second transmission gear to rotate. When the second transmission gear rotates, it drives the main transmission shaft to rotate. When the main transmission shaft rotates, it drives the main support roller to rotate. When the main support roller rotates, it cooperates with the secondary support roller to drive the phosphor copper tube to rotate evenly. When the phosphor copper tube rotates evenly, the first adjusting motor is controlled to start. When the first adjusting motor is turned on, it drives the first adjusting screw to rotate. When the first adjusting screw rotates, the force generated by the threaded connection drives the L-shaped horizontal moving seat to move horizontally and linearly. When the L-shaped horizontal moving seat moves horizontally and linearly, it synchronously drives the focusing probe to move horizontally and linearly, so that the focusing probe can detect the phosphor copper tube horizontally, thereby ensuring that the phosphor copper tube is evenly and comprehensively detected and the accuracy of the detection is guaranteed.

After the inner and outer surfaces of the phosphor copper tube are cleaned with high-frequency vibration, the blower fan 303 is turned on by control. When the blower fan 303 is turned on, air is blown to the aeration plate 302 through the air pipe, so that the aeration plate 302 is aerated inside the cleaning tank 3. When the aeration plate 302 is aerated inside the cleaning tank 3, the flow of water inside the cleaning tank 3 is accelerated, so that the impurities fallen off the inner and outer surfaces of the phosphor copper tube are carried away by the water flow, preventing dirt from being deposited on the inner and outer surfaces of the phosphor copper tube again, improving the cleaning efficiency, thereby achieving the effect of pre-treatment cleaning of the phosphor copper tube, and preventing the dirt and impurities attached to the inner and outer surfaces of the phosphor copper tube from affecting the inspection effect of the inner and outer surface marks.

[0024] When the phosphor copper tube is pretreated and cleaned, the lifting motor 106 is controlled to be turned on and synchronously drives the phosphor copper tube to move upward and straight out of the cleaning tank 3. When the phosphor copper tube moves upward and straight out of the cleaning tank 3, the rotating motor 101 is controlled to be turned on. When the rotating motor 101 is turned on, it will drive the first synchronous wheel 102 to rotate. When the first synchronous wheel 102 rotates, it will drive the second synchronous wheel 103 to rotate through the synchronous belt transmission. When the second synchronous wheel 103 rotates, it will drive the rotating table 2 to rotate. When the rotating table 2 rotates, it will drive the support rod 104 to rotate horizontally. When the support rod 104 rotates horizontally, it will synchronously drive the phosphor copper tube to rotate horizontally. When the phosphor copper tube rotates horizontally to just above the detection tank 4, the lifting motor 106 is controlled to be turned on and synchronously drives the phosphor copper tube to move downward and straight into the inside of the detection tank 4, thereby achieving pretreatment and cleaning of the phosphor copper tube and facilitating the transfer of the phosphor copper tube to the inside of the detection tank 4 for detection.

[0025] When the phosphor copper tube moves to the inside of the detection pool 4, the detection host 5 controls the focus probe 413 to be turned on. When the focus probe 413 is turned on, ultrasonic waves will be emitted to the phosphor copper tube. The ultrasonic waves will propagate in the water inside the detection pool 4. When reaching the outer surface of the phosphor copper tube, part of the energy is reflected back to the focus probe 413 to form a primary interface echo; the other part of the energy enters the phosphor copper tube, and when encountering defects or the other side surface of the phosphor copper tube during the propagation process inside the phosphor copper tube, it is reflected back to the focus probe 413 again to form a secondary interface echo and other defect echoes. The echo signal received by the focus probe 413 is transmitted to the detection host 5, and the detection host 5 amplifies, filters and digitizes the signal, and then generates a scanning signal. At the same time, according to the position information and scanning parameters of the focusing probe 413, the scanning signal is converted into an image to detect and analyze the inner and outer wall traces of the dense phosphor copper tube, and the scanning parameters and detection analysis data are displayed through the display panel 501, thereby facilitating the detection of inner and outer wall traces of the phosphor copper tube. When the focusing probe 413 detects the inner and outer wall marks of the phosphor copper tube, the waterproof motor 112 is turned on by control. When the waterproof motor 112 is turned on, it drives the first transmission gear 113 to rotate. When the first transmission gear 113 rotates, it engages and drives the second transmission gear 114 to rotate. When the second transmission gear 114 rotates, it drives the main transmission shaft 115 to rotate. When the main transmission shaft 115 rotates, it drives the main support roller 116 to rotate. When the main support roller 116 rotates, it cooperates with the auxiliary support roller 120 to drive the phosphor copper tube to rotate. The phosphor copper tube rotates evenly. When the phosphor copper tube rotates evenly, the first adjusting motor 401 is turned on by control. When the first adjusting motor 401 is turned on, the first adjusting screw rod 402 is driven to rotate. When the first adjusting screw rod 402 rotates, the force generated by the threaded connection drives the L-shaped horizontal moving seat 403 to move horizontally and linearly. When the L-shaped horizontal moving seat 403 moves horizontally and linearly, it synchronously drives the focusing probe 413 to move horizontally and linearly, so that the focusing probe 413 can detect the phosphor copper tube horizontally, thereby ensuring that the phosphor copper tube is evenly and comprehensively detected, and ensuring the accuracy of the detection.

[0026] At the same time, by controlling to turn on the second adjusting motor 406, when the second adjusting motor 406 is turned on, it will drive the second adjusting screw rod 407 to rotate. When the second adjusting screw rod 407 rotates, the force generated by the threaded connection will drive the longitudinal moving platform 408 to move linearly inward and outward. When the longitudinal moving platform 408 moves linearly inward and outward, it will synchronously drive the focusing probe 413 to move linearly inward and outward. By controlling to turn on the electric telescopic rod 410, when the electric telescopic rod 410 is turned on, it will drive the L-shaped mounting plate 411 to move linearly up and down. When the L-shaped mounting plate 411 moves linearly up and down, it will drive the focusing probe 413 to move linearly up and down, thereby facilitating the inward and outward and up and down linear movement adjustment of the detection position of the focusing probe 413.

The other part of the energy enters the phosphor copper tube and, when it encounters a defect or the other side surface of the phosphor copper tube during propagation inside the phosphor copper tube, is reflected back to the focusing probe (413) again to form a secondary interface echo and other defect echoes. The echo signal received by the focusing probe (413) is transmitted to the detection host (5). The detection host (5) amplifies, filters and digitally processes the signal, and then generates a scanning signal. At the same time, according to the position information and scanning parameters of the focusing probe (413), the scanning signal is converted into an image to perform trace detection and analysis on the inner and outer walls of the dense phosphor copper tube, and the scanning parameters and detection analysis data are displayed on the display panel (501); S6.
