Description

Technical Field

[0001] This utility model relates to the field of titanium rod quality inspection technology, specifically to a titanium rod quality inspection and flaw detection device. Background Technology

[0002] Titanium rods are widely used in high-end fields such as aerospace and medical. Their internal quality and surface integrity are of paramount importance, and water immersion ultrasonic testing technology is the mainstream method for detecting internal defects.

[0003] The existing testing process requires placing a titanium rod in a water tank filled with coupling water, and using an ultrasonic flaw detector to transmit and receive signals in conjunction with testing equipment to analyze defects. However, this process relies on manual operation and has the following drawbacks: First, it is inconvenient and inefficient, requiring manual adjustment of the flaw detector along the axis of the titanium rod and multiple rotations of the rod to cover the circumference for inspection, making it difficult to guarantee operational stability and accuracy, and easily leading to blind spots in the inspection; Second, the surface of the titanium rod is easily damaged, and the large friction surface with the bottom of the water tank during manual rotation easily causes surface scratches and wear, affecting production quality.

[0004] To address these technical issues, a titanium rod quality inspection and flaw detection device is provided. Utility Model Content

[0005] The purpose of this invention is to provide a titanium rod quality inspection and flaw detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A titanium rod quality inspection and flaw detection device includes a water tank frame, on the upper surface of which a water tank is fixedly installed. Two adjustable-spaced friction-reducing and lifting devices are installed inside the water tank to lift both ends of the titanium rod. A housing is fixedly installed on the rear surface of the water tank, and a transverse circulating moving device is installed inside the housing. A movable rod is rotatably mounted on the front side of the transverse circulating moving device, moving with the device. A mounting base is fixedly installed at the front end of the movable rod, and an ultrasonic probe is detachably installed inside the mounting base.

[0008] Preferably, the friction-reducing lifting device includes a bracket, the rear end of which is integrally formed with a J-shaped part, and a through opening is provided in the J-shaped part. Four nuts are fixedly installed on the lower surface of the J-shaped part, and lifting wheels are rotatably installed between two corresponding nuts via a rotating shaft. The lifting wheels are disposed through the through opening, and the two lifting wheels cooperate to lift the titanium rod. The ultrasonic probe is located directly above the J-shaped part.

[0009] Preferably, a positioning square rod is horizontally fixedly installed inside the water tank, and a U-shaped part is provided at the front end of the bracket. The U-shaped part is slidably installed between the positioning square rod and the inner side wall of the water tank, and a locking bolt A is threaded through the rear surface of the U-shaped part.

[0010] Preferably, the transverse circulating moving device includes a precision lead screw rotatably installed inside the housing, two directional rods fixedly installed inside the housing, and a lead screw motor fixedly installed on the left surface of the housing. The output end of the lead screw motor is fixedly connected to the left end of the precision lead screw. A lead screw slide is slidably installed between the two directional rods, and the lead screw slide is sleeved on the outer surface of the precision lead screw.

[0011] The front surface of the lead screw slide is fixedly mounted with an adapter seat, and the rear end of the movable rod is rotatably mounted in the adapter seat via a rotating shaft, with a damping pad provided between the movable rod and the adapter seat.

[0012] Preferably, the upper surface of the mounting base is provided with an assembly groove, the ultrasonic probe is inserted and installed in the assembly groove, and locking bolts B are screwed onto both the left and right surfaces of the mounting base through the assembly groove, with the opposite ends of the two locking bolts B abutting against the outer surface of the ultrasonic probe.

[0013] Preferably, the horizontal circulating moving device is installed at least 50 centimeters above the opening of the water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes an adjustable-spacing friction-reducing lifting device. Firstly, it employs lifting wheels to create rolling support between the titanium rod and the bottom of the water tank, transforming traditional "sliding friction" into "rolling friction." This significantly reduces the risk of scratches and wear on the titanium rod surface, and solves the problem of surface integrity damage caused by the large friction surface when manually turning the titanium rod. Secondly, the U-shaped section slides along the positioning rod and is fixed by locking bolt A, enabling adaptable lifting of titanium rods of different lengths to meet diverse testing needs.

[0016] By setting up a transverse circulating moving device consisting of a precision lead screw, a directional rod, a lead screw motor, and a lead screw slide, combined with a movable rod with damping pads and an ultrasonic probe assembly structure, the lead screw motor drives the precision lead screw transmission to move the ultrasonic probe smoothly and cyclically along the titanium rod axis, automatically covering the entire axial flaw detection position. This not only replaces the inefficient mode of traditional manual hand-held probe movement, reducing manual labor intensity, but also avoids the risk of missed defects caused by human operation errors by relying on the high-precision transmission characteristics of the precision lead screw. It solves the problems of low efficiency, poor stability, and easy occurrence of detection blind spots when manually adjusting the probe position. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution:

[0025] To achieve the above objectives, this utility model provides the following technical solution: a titanium rod quality inspection and flaw detection device, including a water tank frame 1, a water tank 2 fixedly installed on the upper surface of the water tank frame 1, two adjustable friction-reducing and lifting devices 3 installed in the water tank 2, the two friction-reducing and lifting devices 3 being used to lift both ends of the titanium rod, a box 4 fixedly installed on the rear surface of the water tank 2, a transverse circulating moving device 5 installed in the box 4, a movable rod 6 rotatably arranged on the front side of the transverse circulating moving device 5 and moving with the transverse circulating moving device 5, a mounting base 61 fixedly installed at the front end of the movable rod 6, and an ultrasonic probe 7 detachably installed in the mounting base 61.

[0026] It should be noted that, in combination Figure 3 and Figure 4As shown, the motorcycle lifting device 3 includes a bracket 31. The rear end of the bracket 31 is integrally formed with a J-shaped part 32. A through-hole 321 is opened through the J-shaped part 32. Four nuts 33 are fixedly installed on the lower surface of the J-shaped part 32. Lifting wheels 331 are rotatably installed between two corresponding nuts 33 via a rotating shaft. The lifting wheels 331 are installed through the through-hole 321. The two lifting wheels 331 cooperate to lift the titanium rod. The ultrasonic probe 7 is located directly above the J-shaped part 32.

[0027] By setting up two friction-reducing lifting devices 3 with J-shaped parts 32 and lifting wheels 331, the titanium rod can be separated from the bottom of the water tank 2 during inspection. This reduces the contact area and changes the original "sliding friction" with the bottom of the water tank 2 to "rolling friction" with the lifting wheels 331, which greatly reduces the risk of friction damage to the surface of the titanium rod and avoids the surface scratches and wear problems caused by excessive friction when manually turning the titanium rod in the traditional way.

[0028] In addition, combined Figure 3 and Figure 4 As shown, a positioning rod 21 is horizontally fixedly installed inside the water tank 2. A certain gap is reserved between the positioning rod 21 and the inner wall of the water tank 2. The front end of the bracket 31 is provided with a U-shaped part 34. After the U-shaped part 34 is slidably installed between the positioning rod 21 and the inner wall of the water tank 2, the position of the bracket 31 can be adjusted horizontally to change the distance between the two friction-reducing lifting devices 3, thereby adapting to the lifting work of titanium rods of different lengths and the testing needs of titanium rods of different specifications.

[0029] After adjusting the position of the friction-reducing lifting device 3, during the testing process, in order to prevent the movement of the bracket 31 from affecting the stable testing of the titanium rod, a locking bolt A35 needs to be threaded through and installed on the rear surface of the U-shaped part 34. Manually tightening the locking bolt A35 can fix the position of the bracket 31, thereby ensuring stability during the testing process.

[0030] In addition, combined Figure 1 and Figure 2 As shown, the transverse circulating moving device 5 includes a precision lead screw 51 rotatably installed inside the housing 4, two directional rods 52 fixedly installed inside the housing 4, and a lead screw motor 54 fixedly installed on the left surface of the housing 4. The output end of the lead screw motor 54 is fixedly connected to the left end of the precision lead screw 51. A lead screw slide 53 is slidably mounted between the two directional rods 52. The lead screw slide 53 is sleeved on the outer surface of the precision lead screw 51. An adapter seat 531 is fixedly installed on the front surface of the lead screw slide 53. The rear end of the movable rod 6 is rotatably mounted in the adapter seat 531 through a rotating shaft, and a damping pad is provided between the movable rod 6 and the adapter seat 531.

[0031] In the transverse cyclic moving device 5, the lead screw motor 54 drives the precision lead screw 51 to rotate. With the guidance of the two directional rods 52 on the lead screw slide 53, the lead screw slide 53, the movable rod 6, and the ultrasonic probe 7 can move smoothly along the axis of the titanium rod, automatically completing the full-axis flaw detection coverage of the titanium rod. This eliminates the need for operators to move the probe back and forth laterally, reducing manual labor intensity and transforming the inefficient traditional "manual probe movement" mode into automated operation, thus improving detection efficiency. At the same time, the high-precision transmission characteristics of the precision lead screw 51 ensure the accuracy of the probe's movement trajectory, further reducing the risk of missed defects due to human error.

[0032] Specifically, combined Figure 5 As shown, an assembly groove 611 is provided through the upper surface of the mounting base 61. The ultrasonic probe 7 is inserted and installed in the assembly groove 611. Locking bolts B612 are screwed through the assembly groove 611 on both the left and right surfaces of the mounting base 61. The opposite ends of the two locking bolts B612 are pressed against the outer surface of the ultrasonic probe 7. When replacing the ultrasonic probe 7, the locking bolts B612 can be unscrewed and removed from the assembly groove 611. When installing, the operation is reversed, and the two locking bolts B612 are used to clamp and fix it in the assembly groove 611.

[0033] Combination Figure 1 As shown, the lateral circulation moving device 5 is located on the rear side of the water tank 2, that is, above and behind the liquid in the water tank 2. This prevents the liquid from contacting the precision lead screw 51 in the lateral circulation moving device 5 when the titanium rod is being picked up or put down, thus avoiding affecting the transmission effect and service life. To further ensure that the precision lead screw 51 in the lateral circulation moving device 5 does not contact the liquid, the installation position of the lateral circulation moving device 5 needs to be at least 50 centimeters higher than the opening of the water tank 2. At this height, the precision lead screw 51 can be further away from the liquid in the water tank 2, avoiding its influence.

[0034] Working principle:

[0035] Before use, loosen the locking bolt A35 and adjust the distance between the two friction-reducing lifting devices 3 according to the length of the titanium rod to be inspected. The two friction-reducing lifting devices 3 can use the J-shaped part 32 to lift the titanium rod. After adjustment, tighten the locking bolt A35 to fix the friction-reducing lifting device 3.

[0036] In use, the titanium rod to be inspected is placed inside the J-shaped section 32 of the two friction-reducing lifting devices 3. The two ends of the titanium rod are supported by two lifting wheels 331 within the J-shaped section 32. The support of the lifting wheels 331 reduces the contact area between the titanium rod and the bottom of the water tank 2, thus avoiding excessive friction when rotating to adjust the inspection surface of the titanium rod, which could easily cause wear on its outer surface and affect quality. Then, the front end of the movable rod 6 is flipped towards the titanium rod. After flipping, the ultrasonic probe 7 is positioned above the J-shaped section 32, close to the surface of the titanium rod. At this point, the ultrasonic probe 7 is connected to an external flaw detection instrument. In use, the lateral cyclic moving device 5 is then activated. The lead screw motor 54 drives the precision lead screw 51 to rotate, and the lead screw slide 53 drives the movable rod 6 and the ultrasonic probe 7 to move laterally in a cyclic manner to change the flaw detection position of the ultrasonic probe 7. After the ultrasonic probe 7 moves from the left end of the titanium rod to the right end, the operator manually rotates the titanium rod at one end to change the flaw detection surface. Throughout the entire operation, the operator does not need to move back and forth laterally to complete the flaw detection work on the titanium rod in coordination with the moving ultrasonic probe 7. The operation is convenient and labor-saving, and can improve the detection efficiency.
