Description

Technical Field

[0001] This utility model relates to an ultrasonic cleaning and flaw detection device. Background Technology

[0002] In modern industrial production and precision instrument manufacturing, there are extremely high requirements for the cleaning and flaw detection of components. Traditional cleaning methods often struggle to thoroughly remove dirt from tiny crevices and complex structures, while conventional flaw detection methods have limitations in terms of accuracy and efficiency. Ultrasonic cleaning technology, with its unique cavitation effect, can penetrate deep into tiny crevices for cleaning. Ultrasonic flaw detection technology utilizes the properties of ultrasound waves to detect internal damage by reflecting and refracting when they encounter defects within an object. However, most existing ultrasonic equipment only has a single cleaning or flaw detection function, failing to meet the integrated cleaning and flaw detection needs of actual production. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a device that integrates ultrasonic cleaning and flaw detection functions.

[0004] Technical solution: This utility model discloses an ultrasonic cleaning and flaw detection device, comprising a gun body, an ultrasonic transducer, and a protective cover. The gun body has a chamber inside, and a water outlet communicating with the chamber is located at the left end of the gun body. A water inlet pipe communicating with the chamber is provided on the side of the gun body. The ultrasonic transducer is fixed in the protective cover. The gun body and the protective cover are connected by a hinge, and the protective cover can rotate relative to the gun body to switch between ultrasonic cleaning mode and ultrasonic flaw detection mode.

[0005] Furthermore, the hinge has a first part and a second part that can rotate relative to each other. The first part is fixed to the side of the gun body, and the second part is fixed to the side of the protective cover. When the first part and the second part are in a flat state, it is in ultrasonic cleaning mode, with the ultrasonic transducer head facing the water outlet. When the first part and the second part are in a folded state, it is in ultrasonic flaw detection mode, with the ultrasonic transducer head facing the opposite direction to the water outlet and the ultrasonic transducer head aligned with the surface of the object whose damage needs to be detected.

[0006] Furthermore, the ultrasonic energy emitted by ordinary ultrasonic transducers is dispersed, resulting in unsatisfactory cleaning effects. To address this, an acoustic lens is fixed to the right end of the cleaning gun. In ultrasonic cleaning mode, the head of the ultrasonic transducer faces the acoustic lens, and the ultrasonic waves emitted by the transducer are focused by the acoustic lens, concentrating the ultrasonic energy at the water outlet. The ultrasonic waves are emitted by the ultrasonic transducer, and the acoustic lens focuses them, causing cavitation in the water flowing inside the gun, generating cavitation bubbles. The acoustic lens concentrates the ultrasonic energy at the water outlet, maximizing the utilization of ultrasonic energy, ensuring optimal cleaning results, and improving cleaning efficiency.

[0007] Furthermore, the angle between the axis of the inlet pipe and the axis of the outlet on the horizontal plane is an acute angle, and the water flows obliquely into the chamber from the inlet pipe and makes full contact with the acoustic lens.

[0008] Furthermore, the acoustic lens is a quartz acoustic lens.

[0009] Furthermore, the ultrasonic cleaning and flaw detection device also includes a host computer. The ultrasonic transducer emits ultrasonic flaw detection signals according to the instructions of the host computer. At the same time, the ultrasonic transducer acts as a signal receiving device and transmits the received echo signals to the host computer for damage identification.

[0010] Furthermore, the ultrasonic transducer is a piezoelectric ultrasonic transducer.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following advantages: The ultrasonic cleaning and flaw detection device provided by the present invention can switch between ultrasonic cleaning mode and flaw detection mode based on the hinge, avoiding the cumbersome process of using multiple devices to perform cleaning and flaw detection operations separately, reducing equipment purchase costs and space occupation, greatly improving work efficiency, and providing convenience for scenarios that require simultaneous cleaning and flaw detection operations. It can be applied to scenarios such as precision instrument cleaning and industrial component defect detection. Attached Figure Description

[0022] The gun body 1 has a chamber 8 inside, which is used to store water and transmit ultrasonic waves. The left end of the gun body 1 has a water outlet 6 that connects to the chamber 8. The acoustic lens 3 is fixed to the right end of the gun body 1, and the ultrasonic transducer 2 is fixed in the protective cover 7.

[0023] The hinge 4 has a first part 4.1 and a second part 4.2 that are capable of relative rotation. The first part 4.1 is fixed to the side of the gun body 1, and the second part 4.2 is fixed to the side of the protective cover 7.

[0024] The water inlet pipe 5 is connected to the side of the gun body 1, and the water inlet of the water inlet pipe 5 is connected to the chamber 8. The angle between the axis of the water inlet pipe 5 and the horizontal plane containing the axis of the water outlet 6 is an acute angle. The water flows obliquely into the chamber 8 from the water inlet pipe 5, so that the water flow fully contacts the acoustic lens 3.

[0025] The ultrasonic transducer 2 is connected to the power switch 10 and the host computer 11 respectively.

[0026] In this embodiment, the ultrasonic transducer 2 is a piezoelectric ultrasonic transducer, and the acoustic lens 3 is a quartz acoustic lens.

[0027] like Figure 2 As shown, switch to ultrasonic flaw detection mode. At this time, the first part 4.1 and the second part 4.2 are in a folded state. The ultrasonic transducer head 9 faces the opposite direction to the outlet 6. Align the ultrasonic transducer head 9 with the surface of the object to be damaged. The ultrasonic transducer 2 sends out ultrasonic flaw detection signal according to the instruction of the host computer 11. At the same time, the ultrasonic transducer 2 acts as a signal receiving device and transmits the received echo signal to the host computer 11 for damage 12 identification.

[0029] The ultrasonic waves emitted by the ultrasonic transducer 2 are focused by the acoustic lens 3, concentrating the ultrasonic energy at the water outlet 6. To achieve this, such as... Figure 4 The diagram shows the focusing principle dimensions of the acoustic lens. In this embodiment, the refractive index n2 of quartz is 1.46, the refractive index n1 of water is 1.33, the radius r of the bottom surface of the acoustic lens is 2.5cm, and the radius of curvature R of the top convex plane of the acoustic lens perpendicular to the axis is 2.6cm.

[0033] According to formula (1), the focal length of the ultrasonic wave emitted by the ultrasonic transducer 2 after being focused by the acoustic lens 3 is calculated, that is, the distance f from the top convex plane of the acoustic lens 3 to the water outlet 6 is 20cm; then according to formula (2), the center distance t of the acoustic lens 3 is calculated to be 0.28cm; further according to formula (3), the edge distance t′ of the acoustic lens 3 is calculated to be 0.38cm; finally according to formula (4), the total thickness T of the acoustic lens 3 is calculated to be 0.66cm.

[0034] Based on the above parameters, the radius of curvature, center distance, edge distance, and thickness of the acoustic lens 3 can be fitted.

[0035] Figure 5 The diagram shows the workflow of ultrasonic flaw detection. The rotating hinge switches the ultrasonic flaw detection mode. The ultrasonic transducer is connected to the host computer. The host computer sends an excitation signal, the ultrasonic transducer emits ultrasonic waves for flaw detection, and the ultrasonic transducer receives the echo and transmits it back to the host computer. The host computer uses the echo signal received to determine whether there is damage.

[0036] Figure 6 The diagram shows the ultrasonic cleaning process. Rotating the hinge switches the ultrasonic cleaning mode, turning on the power and connecting the water flow starts the process. The ultrasonic transducer emits ultrasonic waves, and the acoustic lens focuses the ultrasonic waves to the water outlet, maximizing the utilization of ultrasonic energy and cleaning the items.
