The detection module 50 is used to perform phased array detection on the bolt through the ultrasonic probe 51 when the sliding frame 30 moves toward the bolt direction.

[0036] Specifically, the bolt phased array detection device is provided with a supply slip ring 10, a mounting frame 20, a sliding frame 30, an axial drive unit 40 and a detection module 50. When performing the bolt detection work, the supply slip ring 10 can be arranged on one side of the bolts arranged at intervals along the annular direction, the sliding frame 30 is slidably connected to the supply slip ring 10 along the circumferential direction of the supply slip ring 10, and can slide to one side of each bolt by sliding along the circumferential direction of the supply slip ring 10. The sliding frame 30 is slidably connected to the mounting frame 20 along the axial direction of the supply slip ring 10, the detection module 50 is installed on the sliding frame 30, and the axial drive unit 40 is connected to the sliding frame 30. The detection module 50 is connected by driving the sliding frame 30 to slide along the mounting frame 20, thereby driving the detection module 50 to move toward or away from the bolt. When the detection module 50 moves toward the bolt, the ultrasonic wave emitted by the ultrasonic probe 51 realizes the phased array detection of the bolt. After completing the detection of the bolt, the axial drive unit 40 drives the detection module 50 to retreat, and then controls the mounting frame 20 to slide, so that the detection module 50 moves to the next adjacent bolt to detect the bolt. Finally, through the above detection method, the detection of each bolt in the circumferential direction is realized, which effectively reduces the manpower required for bolt detection and avoids missed detection of bolts.

[0037] In this embodiment, the slip ring 10 is an annular structure, and its inner diameter can be adaptively set according to the size of a circle formed by bolts arranged in an annular manner on the part or equipment to be inspected.

[0039] Optionally, a sliding limit frame 21 is provided at the bottom of the mounting frame 20, and the sliding limit frame 21 is located on both sides of the supply slip ring 10 and is slidably connected to the supply slip ring 10. Specifically, through the cooperation between the sliding limit frame 21 and both sides of the supply slip ring 10, the sliding limit frame 21 can be clamped with the supply slip ring 10 to achieve stable sliding of the sliding limit frame 21 along the supply slip ring 10.

[0040] Optionally, annular tracks 11 are provided on both sides of the supply slip ring 10, and the sliding limit frame 21 is provided with opposite first sliders 211, and the first sliders 211 are slidably connected to the two annular tracks 11.

Specifically, since the ring gear 61 is fixed, the first motor drives the driving gear to rotate, and then the driving gear moves along the ring gear 61, thereby driving the mounting frame 20 to slide, thereby realizing the transposition of the mounting frame 20.

[0044] Optionally, an annular mounting groove 12 is provided on the outer side of the supply slip ring 10, and the ring gear 61 is fixed to the annular mounting groove 12. Specifically, the annular mounting groove 12 can accommodate the ring gear 61, so as to avoid blocking the sliding of the mounting frame 20, so that the mounting frame 20 can slide closer to the supply slip ring 10, and improve the stability of the mounting frame 20 when sliding.

[0045] Optionally, the mounting frame 20 is provided with a linear slide rail 22, the linear slide rail 22 extends in the axial direction of the supply slip ring 10, and the end of the sliding frame 30 is provided with a second slider 31, and the second slider 31 is slidably connected to the linear slide rail 22. Specifically, since the linear slide rail 22 extends in the axial direction of the supply slip ring 10, the second slider 31 on the sliding frame 30 cooperates with the linear slide rail 22 on the mounting frame 20, so that the mounting frame 20 can slide stably along the axial direction of the supply slip ring 10.

[0046] Optionally, the axial drive unit 40 includes a drive module 41 and a screw rod 42, the screw rod 42 extends along the axial direction of the supply slip ring 10 and is rotatably connected to the mounting frame 20, the drive module 41 is connected to the screw rod 42, and is used to drive the screw rod 42 to rotate, and the sliding frame 30 is threadedly connected to the screw rod 42. Specifically, the drive module 41 drives the screw rod 42 to rotate, thereby driving the sliding frame 30 to move axially along the screw rod 42, and since the screw rod 42 extends along the axial direction of the supply slip ring 10, it can drive the sliding frame 30 to slide along the axial direction of the supply slip ring 10.

[0048] Optionally, the driving module 41 includes a second motor 411 and a belt 412, wherein the second motor 411 is fixed to the mounting frame 20, and the belt 412 is sleeved on the screw rod 42 and the shaft of the second motor 411. Specifically, when the second motor 411 is started, the screw rod 42 can be driven to rotate through the transmission of the belt 412, thereby realizing the driving of the screw rod 42.

[0049] Optionally, the detection module 50 also includes a longitudinal slide 52, a longitudinal slider 53, a longitudinal drive cylinder 54, a transverse slide 55, a transverse slider 56, a transverse drive cylinder 57 and a mounting seat 58, the longitudinal slide 52 is fixed to the sliding frame 30, the longitudinal slider 53 is connected to the longitudinal slide 52 along the radial sliding direction of the supply slip ring 10, the longitudinal drive cylinder 54 is installed on the longitudinal slide 52 and connected to the longitudinal slider 53, the transverse slide 55 is fixed to the longitudinal slider 53, the transverse slider 56 is slidably connected to the transverse slide 55, the transverse drive cylinder 57 is fixed to the transverse slide 55 and connected to the transverse slider 56, the mounting seat 58 is fixed to the transverse slider 56, and the ultrasonic probe 51 is installed on the mounting seat 58.

[0050] Specifically, when inspecting the bolts, the longitudinal drive cylinder 54 drives the longitudinal slider 53 to slide along the radial direction of the slip ring 10, thereby driving the ultrasonic probe 51 in the first direction, and the transverse drive cylinder 57 drives the transverse slider 56 to slide in a direction perpendicular to the radial direction of the slip ring, thereby driving the ultrasonic probe 51 in a second direction perpendicular to the first direction, thereby enabling inspection of various parts of the cross section of the bolt to be inspected, thereby ensuring the inspection quality of the bolts.

[0051] It can be understood that the sliding distances of the longitudinal slider 53 and the transverse slider 56 should be adaptively adjusted according to the size of the bolt.

[0052] The specific working principle of the bolt phased array detection device of the embodiment of the utility model is as follows: when detecting the bolts arranged in an annular manner, the slip ring 10 is installed on one side of each bolt, the second motor 411 is started to drive the ultrasonic probe 51 to move in the direction of the bolt to be tested, the longitudinal drive cylinder 54 and the transverse drive cylinder 57 are started to make the ultrasonic probe 51 scan the bolt. During the scanning process, the ultrasonic probe 51 performs phased array detection on the bolt by emitting ultrasonic waves. After completing the detection of the bolt, the second motor 411 is started to drive the ultrasonic probe 51 to retract, and then the first motor is started to drive the mounting frame 20 to slide, so that the ultrasonic probe 51 moves to the next adjacent bolt, and the detection of the bolt is completed again through the above detection steps, and finally the automatic detection of the bolts spaced in an annular manner is realized, thereby reducing the manpower required for the bolt detection process and effectively ensuring the detection quality of the bolt.
