Description

Technical Field

[0001] This utility model relates to the field of ultrasonic weld point flaw detection technology, and in particular to an online detection instrument for internal defects in steel wire weld points based on ultrasonic waves. Background Technology

[0002] Ultrasonic solder joint inspection is a non-contact inspection technology that assesses the quality of solder joints through the propagation and reflection of ultrasonic waves. Its principle is based on the differences in the propagation speed of ultrasonic waves in different media (such as metals and solder) and the reflection (or scattering) encountered at interfaces during propagation.

[0003] A weld joint ultrasonic testing instrument with multi-angle detection, patent number CN202220180835.X, includes a U-shaped bracket. Two symmetrically arranged connecting shafts are rotatably connected to the U-shaped bracket via bearings. A single weld joint ultrasonic testing instrument body is fixed between the two connecting shafts. An angle adjustment mechanism is installed between one of the connecting shafts and the U-shaped bracket. An ultrasonic testing probe is connected to the weld joint ultrasonic testing instrument body via a data cable. A workpiece placement stage is fixed to the rear wall of the U-shaped bracket. An adjustable automatic horizontal movement auxiliary mechanism connects the workpiece placement stage and the ultrasonic testing probe. This invention solves the problem of unstable probe handling by operators in existing technologies.

[0004] However, the above patent still has the following defects in actual use: When the above patent is used to inspect the weld points of long strips such as steel wires, the steel wires are very long and the device lacks traction measures. Therefore, the staff needs to manually feed the material and move the steel wire weld points to the workpiece placement table for inspection, which is extremely inconvenient. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing an online detection instrument for internal defects of steel wire welds based on ultrasound.

[0006] The technical problem to be solved by this utility model is to provide an online detector for internal defects in steel wire welds based on ultrasound to solve the problem of existing devices that cannot automatically feed materials.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An online ultrasonic-based steel wire weld joint internal defect detector includes: a flaw detection box with openings at the top and bottom, and feeding troughs on both sides of the box. A traction assembly is installed within the inner cavity of both feeding troughs. A lifting frame is movably mounted on the front and rear sides of the outer wall of the flaw detection box, arranged in an "n" shape.

The device is plugged into the top of the display screen. The traction assembly includes four traction rollers, arranged in pairs, one above the other. Each of the four traction rollers has a round shaft fixedly mounted through it. Both ends of the round shafts pass through the outer wall of the flaw detection box and are rotatably connected to it. Gears are fixedly mounted through the outer walls of the two round shafts on the left side, and the two gears mesh with each other. Grooved wheels are fixedly mounted near one end of the outer walls of the four round shafts. A belt is connected to the grooved wheels on both sides for transmission.

[0008] Preferably, a base is fixedly installed on the outer wall of the motor, and the base is fixedly connected to the outer wall of the flaw detection box.

[0009] Preferably, the outer wall of the flaw detection box is provided with sliding grooves on both the front and rear sides, and a slider is slidably connected to the inner cavity of each of the two sliding grooves.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The ultrasonic-based online defect detector for internal defects in steel wire welds, as shown in this embodiment, includes: a flaw detection box 1, with openings at the top and bottom, and feeding troughs 2 on both sides of the flaw detection box 1. A traction assembly 3 is installed within the inner cavity of both feeding troughs 2. A lifting frame 6 is movably mounted on the front and rear sides of the outer wall of the flaw detection box 1, arranged in an "n" shape. An ultrasonic probe 19 is mounted on the top of the inner wall of the lifting frame 6. A display screen 17 is fixedly mounted on the outer wall of the lifting frame 6. A data cable 18 is connected to the outer wall of the ultrasonic probe 19, with one end of the data cable 18 penetrating through the outer wall of the lifting frame 6 and movably connected to it. One end is plugged into the top of the display screen 17; the traction assembly 3 includes four traction rollers 31, which are arranged in pairs, one above the other, and each of the four traction rollers 31 is fixedly mounted with a round shaft 32 through it. The two ends of the round shaft 32 pass through the outer wall of the flaw detection box 1 and are rotatably connected to the outer wall of the flaw detection box 1. Gears 33 are fixedly mounted through the outer wall of the two round shafts 32 on the left side, and the two gears 33 mesh with each other. Grooved wheels 34 are fixedly mounted on the outer wall of the four round shafts 32 near one end. Belts 35 are connected to the grooved wheels 34 on both the left and right sides for transmission. A motor 36 is also fixedly mounted on the outer wall of the flaw detection box 1. The output end of the motor 36 is fixedly connected to the end of the adjacent round shaft 32.

[0024] Specifically, the steel wire to be tested is first passed through multiple traction rollers 31 and the flaw detection box 1, and the ultrasonic probe 19 is driven to perform flaw detection on the weld points on the steel wire. The flaw detection results can be viewed directly on the display screen 17. Then, the motor 36 is driven, which drives the corresponding circular shaft 32 to rotate. The circular shaft 32 drives the corresponding gear 33 to rotate. The gear 33 drives another gear 33 to rotate synchronously. The other gear 33 drives the corresponding circular shaft 32 to rotate. At the same time, the two circular shafts 32 drive the other two circular shafts 32 to rotate synchronously through the corresponding grooved wheel 34 and belt 35. Thus, the four circular shafts 32 drive the four traction rollers 31 to rotate synchronously, which is used to provide traction for the steel wire, so that the steel wire continuously enters the flaw detection box 1 for flaw detection.

[0025] In this embodiment, as Figures 2-3 As shown; a base 37 is fixedly installed on the outer wall of motor 36, and the base 37 is fixedly connected to the outer wall of flaw detection box 1.

[0026] Specifically, by setting up the base 37, the installation strength between the motor 36 and the outer wall of the flaw detection box 1 is improved, ensuring that the motor 36 is sufficiently stable during subsequent operation.

[0027] In this embodiment, as Figures 1-4As shown; the outer wall of the flaw detection box 1 has sliding grooves 8 on both the front and rear sides, and the inner cavity of each sliding groove 8 is slidably connected to a slider 7. The slider 7 is fixedly connected to the inner wall of the lifting frame 6, and a side frame 9 is also fixedly connected to one side of the outer wall of the slider 7. An electric push rod 10 is fixedly connected to the top of the side frame 9, and a top frame 11 is fixedly connected to the top of the electric push rod 10. The top frame 11 is fixedly connected to the inner wall of the flaw detection box 1.

[0028] Specifically, by driving two electric actuators 10 to move two side frames 9, the side frames 9 move sliders 7, the two sliders 7 together move lifting frame 6, and the lifting frame 6 moves ultrasonic probe 19, thus realizing the lifting operation of ultrasonic probe 19. When the equipment is idle, ultrasonic probe 19 can be stored inside flaw detection box 1 to avoid the problem of ultrasonic probe 19 being damaged by collisions when it is exposed to the outside.

[0029] In this embodiment, as Figure 2 As shown; the bottom of the flaw detection box 1 is embedded and fixedly installed with a bottom cover 4, and the bottom cover 4 has mounting holes 5 near the four corners.

[0030] Specifically, the multiple mounting holes 5 on the bottom cover 4 allow for the passage of fasteners such as fixing bolts and fixing screws, enabling the overall equipment to be fixedly installed.

[0031] In this embodiment, as Figures 4-5 As shown; the top of the ultrasonic probe 19 is fixedly connected to a movable block 13, and the top of the lifting frame 6 is provided with a long groove 12, and the movable block 13 is slidably connected to the inner cavity of the long groove 12.

[0032] Specifically, by sliding the movable block 13 inside the long groove 12, the horizontal position of the ultrasonic probe 19 can be adjusted, enabling the ultrasonic probe 19 to perform flaw detection operations over a larger area.

[0033] In this embodiment, as Figures 4-5 As shown; a motor 2 14 is fixedly installed on the outer wall of the lifting frame 6. A screw 16 is fixedly connected to the output end of the motor 2 14. One end of the screw 16 passes through the lifting frame 6 and the movable block 13 and is rotatably connected to the lifting frame 6. The screw 16 is threadedly connected to the movable block 13.

[0034] Specifically, the drive motor 14 drives the screw 16 to rotate, the screw 16 drives the movable block 13 to move horizontally, and the movable block 13 drives the ultrasonic probe 19 to move, thereby achieving the purpose of automatically controlling the ultrasonic probe 19 to change position.

[0035] In this embodiment, as Figures 4-5 As shown; a base 15 is fixedly connected to the outer wall of motor 2 14, and the base 2 15 is fixedly connected to the outer wall of lifting frame 6.

[0036] Specifically, by setting the base 2 15, the installation strength between the motor 2 14 and the outer wall of the lifting frame 6 is improved, thereby ensuring that the motor 2 14 is sufficiently stable during subsequent operation.
