Description

Technical Field

[0001] This invention relates to the field of titanium rod testing technology, specifically to an automatic ultrasonic testing device for titanium rods. Background Technology

[0002] Titanium rods are rod-shaped materials made of metallic titanium or titanium alloys. They possess high strength, low density, excellent corrosion resistance, and biocompatibility, making them key materials in high-end fields such as aerospace, medical implants, and chemical equipment. However, defects such as porosity, inclusions, or microcracks can occur within titanium rods during the smelting and forging processes. These defects can severely affect their mechanical properties and safety, necessitating non-destructive testing methods for quality control. Among these methods, water immersion ultrasonic testing is widely used due to its high stability and accuracy. This method involves simultaneously immersing the titanium rod and an ultrasonic probe in water, using water as a uniform acoustic coupling medium. This effectively avoids signal fluctuations caused by uneven pressure in direct contact testing, allowing acoustic waves to penetrate the material efficiently and vertically. This enables accurate identification and location of minute internal defects, making it particularly suitable for large-volume, regularly shaped titanium rod products with stringent quality requirements.

[0003] However, water immersion testing also has certain limitations in practical applications, especially for large or heavy titanium bars, where the loading and unloading process is complex: before testing, hoisting equipment and multiple people are needed to move the titanium bar into the water tank and adjust it to the designated testing position within the tank; after testing, the same process must be repeated to remove it. These titanium bars are large and heavy, and frequent hoisting and positioning are not only inefficient but also increase the workload, affecting the testing efficiency in large-scale production. Therefore, we propose a novel ultrasonic automatic testing device for titanium bars. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic ultrasonic testing device for titanium rods, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic ultrasonic testing device for titanium rods, comprising a water tank and brackets symmetrically mounted on the water tank, an electric slide rail fixedly mounted between the two brackets, a slider slidably connected to the electric slide rail, an electric telescopic rod fixedly mounted on the slider, an ultrasonic probe fixedly mounted at the telescopic end of the electric telescopic rod, and a loading and unloading structure provided on the side of the water tank.

[0006] The loading and unloading structure includes a conveying rod with V-shaped slots at both ends. Compressible airbags are symmetrically installed at the bottom of the conveying rod. Air guide bends communicating with the inner cavity of the compressible airbags are fixedly installed on both sides of the compressible airbags. The compressible airbags are connected to the inner cavity of the air guide bends. An air box is fixedly connected to the end of the air guide bends away from the compressible airbags. An air cavity is opened inside the air box. The air guide bends are connected to the inner cavity of the air cavity. A piston adapted to the air cavity is slidably connected to the inner cavity of the air cavity. An inclined rod penetrating the air box is fixedly installed on the piston. A telescopic spring is fixedly installed between the piston and the inner cavity of the air cavity.

[0007] Preferably, there are two conveying rods, and the distance between the two conveying rods is less than the length of the slider that can move on the electric slide rail.

[0008] Preferably, the air box is fixedly installed at the V-shaped groove on the material conveying rod and is parallel to one side of the V-shaped groove.

[0009] Preferably, a soft rubber block is fixedly installed at the end of the inclined rod away from the piston, and the inclined rod is located on the axis of the telescopic spring.

[0010] Preferably, the loading and unloading structure further includes a rotating seat symmetrically installed on the side of the water tank. The inner cavity of the rotating seat is rotatably connected to a rotating head adapted to the rotating seat. A shaft passing through the rotating head is fixedly installed at the axis of the rotating head. The shaft is rotatably connected to the rotating seat. The rotating head is fixedly connected to the conveying rod, and the extension end of the rotating head is perpendicular to the conveying rod.

[0011] Preferably, the shortest distance from the lowest point of the electric slide rail to the axis of the rotating head is greater than half the length of the conveying rod.

[0012] Preferably, one end of the shaft is provided with a servo motor and a gearbox, both of which are fixedly connected to the water tank. The output shaft of the servo motor is fixedly connected to the input shaft of the gearbox, and the output shaft of the gearbox is fixedly connected to the end of the shaft.

[0013] Preferably, a roller groove is provided on the V-shaped opening at one end of the conveying rod inside the water tank. The inner cavity of the roller groove is rotatably connected to two rollers through a roller shaft. A waterproof motor is fixedly installed on the side of one of the conveying rods. A drive rod is fixedly installed on the output end of the waterproof motor. The drive rod passes through the conveying rod and is fixedly connected to the roller shaft on the roller away from the air box.

[0014] Preferably, an airbag compression block that is fixedly connected to the side of the water tank is provided below the compressible airbag.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a loading and unloading structure, the material conveying rod is driven to rotate by a servo motor, realizing automatic loading and unloading of titanium rods. This eliminates the need for frequent hoisting and manual intervention, significantly improving testing efficiency and reducing operational intensity.

[0017] 2. By setting a structure that combines a V-shaped groove with a roller groove, positioning is achieved using the weight of the titanium rod itself. This solves the problems of difficult positioning of the titanium rod and the need for an additional limiting mechanism, realizing the integration of feeding and positioning, and simplifying the operation process.

[0018] 3. By setting up pneumatic components such as compressible airbags, air boxes, and inclined rods, the effective length of the slot is automatically expanded during the rotation of the conveyor rod, which effectively prevents the titanium rod from slipping due to instability of the center of gravity during the transfer process, thus improving the safety and stability of loading and unloading.

[0030] This invention provides a technical solution:

[0031] Please see Figures 1 to 8 An automatic ultrasonic testing device for titanium rods includes a water tank 1 and brackets symmetrically mounted on the water tank 1. An electric slide rail 2 is fixedly installed between the two brackets. A slider 3 is slidably connected to the electric slide rail 2. An electric telescopic rod 4 is fixedly installed on the slider 3. An ultrasonic probe 5 is fixedly installed at the telescopic end of the electric telescopic rod 4. A loading and unloading structure 6 is provided on the side of the water tank 1.

[0032] The loading and unloading structure 6 includes a conveying rod 601. V-shaped slots 602 are provided at both ends of the conveying rod 601. Compressible airbags 603 are symmetrically installed at the bottom of the conveying rod 601. Air guide bends 604 communicating with the inner cavity of the compressible airbag 603 are fixedly installed on both sides of the compressible airbag 603. The compressible airbag 603 communicates with the inner cavity of the air guide bends 604. An air box 605 is fixedly connected to the end of the air guide bends 604 away from the compressible airbag 603. An air chamber 606 is opened inside the air box 605. The air guide bends 604 communicate with the inner cavity of the air chamber 606. A piston 607 adapted to the air chamber 606 is slidably connected to the inner cavity of the air chamber 606. An inclined rod 608 penetrating the air box 605 is fixedly installed on the piston 607. A telescopic spring 609 is fixedly installed between the piston 607 and the inner cavity of the air chamber 606.

[0033] When the conveyor rod 601 rotates and lowers, the compressible air bladder 603 at the bottom is compressed by the air bladder compression block 11. The internal gas enters the air chamber 606 inside the air box 605 through the air guide bend 604, pushing the piston 607 to overcome the resistance of the telescopic spring 609, causing the inclined rod 608 to extend out of the air box 605, thereby dynamically expanding the effective protective length of the V-shaped slot 602. This process is carried out automatically during the loading and unloading stages. Its key function is to effectively abut against the titanium rod when it slides by gravity or is hoisted, preventing accidental slippage due to inertia, and significantly improving the stability and safety of automated transfer of large titanium rods.

[0034] In some embodiments, the number of conveying rods 601 is two, and the distance between the two conveying rods 601 is less than the length of the slider 3 that can move on the electric slide rail 2.

[0035] In this embodiment, two conveying rods 601 jointly support both ends of the titanium rod, ensuring its stable and horizontal entry into the testing station. Their core function is to limit the axial placement range of the titanium rod, ensuring that when the slider 3 on the electric slide rail 2 moves the ultrasonic probe 5, the effective scanning stroke of the probe can completely cover the titanium rod, thus guaranteeing comprehensive ultrasonic testing without any omissions. Simultaneously, during the adjustment of the loading / unloading structure 6, the electric telescopic rod 4 and the ultrasonic probe 5 are staggered from the loading / unloading structure 6, preventing them from affecting the rotation of the loading / unloading structure 6.

[0036] In some embodiments, the air box 605 is fixedly installed at the V-shaped slot 602 on the conveying rod 601 and is parallel to one side of the V-shaped slot 602.

[0037] In this embodiment, during operation, when the inclined rod 608 extends from the air box 605 under air pressure, its installation position is parallel to one side of the V-shaped slot 602, ensuring that the extension direction of the inclined rod 608 is consistent with the guide slope of the slot. Its core function is to ensure that the extended inclined rod 608 can accurately extend its protective boundary along the V-shaped slot 602, providing immediate and unidirectional lateral restraint for the titanium rod sliding into the slot. Thus, without altering the original slot structure, it most effectively collaborates with the V-shaped slot to support and prevent slippage of the titanium rod, enhancing the structural synergy and protective effect.

[0038] In some embodiments, a soft rubber block is fixedly installed at the end of the slant rod 608 away from the piston 607, and the slant rod 608 is located on the axis of the telescopic spring 609.

[0039] In this embodiment, when the inclined rod 608 is pushed out by air pressure and comes into contact with the surface of the titanium rod, the soft rubber block at its end undergoes elastic deformation. Its core function is to effectively buffer the rigid impact between the inclined rod and the titanium rod through the flexible contact of the rubber block, avoiding scratches on the surface of the rod. At the same time, the inclined rod 608 and the telescopic spring 609 remain coaxial, ensuring that the piston 607 is subjected to uniform force and has a straight movement trajectory, preventing the inclined rod 608 from deviating or getting stuck in the air chamber 606, and ensuring the reliability and smoothness of the protective mechanism's operation.

[0040] Please see Figure 3 and Figure 4 The loading and unloading structure 6 also includes a rotating seat 610 symmetrically installed on the side of the water tank 1. The inner cavity of the rotating seat 610 is rotatably connected to a rotating head 611 adapted to the rotating seat 610. A shaft 612 passing through the rotating head 611 is fixedly installed at the axis of the rotating head 611. The shaft 612 is rotatably connected to the rotating seat 610. The rotating head 611 is fixedly connected to the conveying rod 601, and the extended end of the rotating head 611 is perpendicular to the conveying rod 601.

[0041] The servo motor 613 drives the shaft 612 to rotate precisely within the rotating seat 610 via the reduction gearbox 614, thereby causing the rotating head 611 and the vertically fixed conveyor rod 601 to rotate smoothly around the axis of the shaft 612. Its core function is to form a stable and reliable rotation fulcrum, accurately converting the rotational motion of the servo motor 613 into the reciprocating oscillation of the conveyor rod 601 between horizontal and inclined positions, thus realizing the automatic transfer and attitude conversion of the titanium rod between the water tank and the external workstation. It is the basic support and motion hub for the entire loading and unloading structure to achieve the automated flipping function.

[0042] In some embodiments, the shortest distance from the lowest point of the electric slide rail 2 to the axis of the rotating head 611 is greater than half the length of the conveying rod 601.

[0043] In this embodiment, this dimension is set during operation to ensure that when the conveying rod 601 is flipped upwards around the axis of the rotating head 611 to a horizontal or higher position, its entirety (especially one end inside the water tank 1) is completely within the space below the electric slide rail 2. Its core function is to provide sufficient interference-free space for the flipping movement of the conveying rod 601, preventing the conveying rod 601 from colliding with the electric slide rail 2, the slider 3, and the electric telescopic rod 4 and ultrasonic probe 5 during the loading and unloading flipping process, thus ensuring the independence and safety of the titanium cylinder detection and loading / unloading actions.

[0044] Please see Figure 3 and Figure 4A servo motor 613 and a gearbox 614 are provided at one end of the shaft 612. Both the servo motor 613 and the gearbox 614 are fixedly connected to the water tank 1. The output shaft of the servo motor 613 is fixedly connected to the input shaft of the gearbox 614, and the output shaft of the gearbox 614 is fixedly connected to the end of the shaft 612.

[0045] The servo motor 613 provides the original rotational power, which is reduced in speed and amplified in torque by the gearbox 614 before being smoothly output to the shaft 612. Its core function is to provide a controllable, sufficient torque and stable drive source for the entire loading and unloading structure 6, ensuring that the conveying rod 601 can perform precise flipping movements at appropriate speed and torque, thus meeting the power requirements and motion control for the automated transfer of titanium rods.

[0046] Please see Figures 1-4 The conveying rod 601 has a roller groove 7 on the V-shaped slot 602 at one end inside the water tank 1. The inner cavity of the roller groove 7 is rotatably connected to two rollers 8 through the roller shaft. A waterproof motor 9 is fixedly installed on the side of one of the conveying rods 601. A drive rod 10 is fixedly installed at the output end of the waterproof motor 9. The drive rod 10 passes through the conveying rod 601 and is fixedly connected to the roller shaft on the roller 8 away from the air box 605.

[0047] During operation, when the titanium rod falls into the V-shaped groove in the water tank 1 and settles firmly in the roller groove 7, two rollers 8 contact and support the titanium rod from both sides. The waterproof motor 9 drives one of the rollers 8 to rotate actively via the drive rod 10, using friction to drive the titanium rod to rotate at a constant speed around its own axis. Its core function is to cooperate with the axially moving ultrasonic probe 5 to achieve spiral scanning detection of the outer wall of the titanium rod, ensuring comprehensive detection coverage and automation, eliminating the need for an additional drive mechanism.

[0048] Please see Figures 1-5 Below the compressible airbag 604, there is an airbag compression block 11 that is fixedly connected to the side of the water tank 1.

[0049] When the conveyor boom 601 is flipped and lowered, the compressible airbag 603 at its bottom can accurately contact and be compressed with the airbag compression block 11 fixed to the side of the water tank 1. Its core function is to act as a reliable mechanical trigger point, converting the downward rotation of the conveyor boom 601 into a stable compression of the compressible airbag 603, thereby triggering the subsequent pneumatic protection mechanism (such as the extension of the inclined rod 608). The whole process requires no additional control and the structure is simple and reliable.

[0050] In practical use, the working principle of this invention is as follows:

[0051] When inspecting large and heavy titanium rods, the servo motor 613 is first controlled to rotate forward by an external controller. The output shaft of the servo motor 613 is reduced in speed by the gearbox 614 and then drives the shaft 612 to rotate. To accurately control the rotation angle of the shaft 612, a rotary encoder can be installed on the outside of the shaft 612 to achieve closed-loop control. The rotation of the shaft 612 is transmitted to the conveying rod 601 located outside the water tank 1 through the rotating seat 610 and the rotating head 611, causing it to rotate slowly downwards. During the descent of the conveyor rod 601, the compressible air bladder 603 at its bottom gradually contacts the air bladder compression block 11 fixed to the side of the water tank 1. After the air bladder is compressed, the internal air enters the air chamber 606 of the air box 605 through the air guide bend 604, pushing the piston 607 to move along the air chamber 606 and compressing the telescopic spring 609, thereby causing the inclined rod 608 to extend out of the air box 605, extending the effective length of the V-shaped slot 602, effectively preventing the titanium rod from slipping due to instability during placement and transfer, and improving the safety of loading and unloading (the air originally present in the air chamber 606 is discharged to the outside through the gap where the inclined rod 608 and the air box 605 pass through).

[0052] After the titanium rod is stably placed onto the V-shaped slot 602 of the conveyor rod 601 outside the water tank by the external hoisting equipment (the diameter of the selected titanium rod should preferably be smaller than the distance between the two highest points of the roller slot 7 to ensure that the roller 8 can stably contact and drive the titanium rod), the external controller controls the servo motor 613 to reverse, driving the shaft 612 to slowly rotate in the opposite direction. Through the rotating head 611, the conveyor rod 601 inside the water tank 1 gradually descends, while the conveyor rod 601 outside the water tank 1 rises accordingly. The reversal process must be kept at a low speed and stable to avoid the titanium rod from slipping out of the slot due to excessive inertia caused by excessive rotation. During this process, the compressible air bladder 603 at the bottom of the conveying rod 601 in the water tank is also pressurized. The gas enters the air chamber 606 through the air guide bend 604, pushing the inclined rod 608 to slowly extend, further extending the protective length of the V-shaped slot 602. Combined with the weight of the titanium rod itself, it slides smoothly into the V-shaped slot 602 of the conveying rod 601 in the water tank, realizing automatic and continuous feeding operation.

[0053] When the titanium rod enters the water tank and lands in the roller groove 7, the roller 8 contacts the surface of the titanium rod. By pre-setting the rotation angle of the conveyor rod 601, it can be ensured that the titanium rod is accurately positioned directly below the ultrasonic probe 5, eliminating the need for additional limiting mechanisms in the water tank 1. This achieves integrated feeding and positioning, significantly simplifying the operation process. Subsequently, the electric telescopic rod 4 is controlled to adjust the ultrasonic probe 5 to the optimal detection distance, and the electric slide rail 2 is activated to move the ultrasonic probe 5 along the axis of the titanium rod. At the same time, the waterproof motor 9 (the circuit connection method of the waterproof motor 9 is common knowledge in the field and is therefore not described; the waterproof motor 9 can be self-powered or externally powered) drives the roller 8, which is fixedly connected to it, to rotate through the drive rod 10, causing the titanium rod to rotate along the axis, realizing the helical scanning detection of the titanium rod by the ultrasonic probe 5. The ultrasonic flaw detector is electrically connected to the ultrasonic probe 5, receiving and analyzing the detection data in real time, and outputting the defect assessment results (the ultrasonic flaw detector is common knowledge familiar to those skilled in the art and is therefore not shown in the figure or emphasized in the text).

[0054] After the test is completed, the controller controls the servo motor 613 to rotate forward again, slowly raising the conveyor rod 601 in the water tank 1. As the conveyor rod 601 rises, the compressible air bladder 603 gradually separates from the air bladder compression block 11, the telescopic spring 609 returns to its original deformation, and the air in the air chamber 606 is forced back into the compressible air bladder 603. The inclined rod 608 then retracts into the air box 605. Under the restoring elastic force of the telescopic spring 609, the titanium rod smoothly slides back to the conveyor rod 601 outside the water tank along the V-shaped groove 602. At this time, the inclined rod 608 on the conveyor rod 601 outside the water tank 1 extends again, providing secondary protection and ensuring that the titanium rod will not accidentally slip during the discharge process, thus completing the entire automated unloading process.

[0055] This device integrates mechanical transmission, pneumatic assistance, and electrical control to automate the entire process of titanium rod loading, positioning, testing, and unloading. It effectively solves the problems of frequent hoisting, difficult positioning, high operational intensity, and low efficiency in water immersion testing of large titanium rods, and is suitable for efficient and continuous testing of batches of titanium rods.

[0056] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
