Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection devices, and in particular to a device for detecting cracks in die-cast aluminum housings. Background Technology
[0002] In modern industrial production, die-cast aluminum enclosures are widely used in aerospace, automotive manufacturing, communication equipment, and many other fields due to their high strength, lightweight, and excellent heat dissipation performance. However, defects such as cracks inevitably occur during the production and use of die-cast aluminum enclosures. These cracks not only affect the structural strength and service life of the enclosure but can also cause safety accidents and result in serious economic losses. Therefore, crack detection of die-cast aluminum enclosures and timely identification and handling of defects have become crucial links in ensuring product quality and production safety.
[0003] The existing crack detection device for die-cast aluminum enclosures mainly consists of a probe, a transmitting circuit, a receiving circuit, and a display screen. Its working principle is based on the reflection characteristics of ultrasound. The transmitter circuit of the flaw detector generates high-frequency electrical pulses to excite the probe, causing the probe to convert the electrical signal into ultrasonic waves that are transmitted to the die-cast aluminum enclosure. When the ultrasonic waves encounter internal defects, reflection, refraction, and scattering occur. The reflected ultrasonic signals are received by the probe, converted back into electrical signals, and then amplified and filtered by the receiving circuit before being displayed as waveforms or images on the display screen. Operators analyze the waveform characteristics on the display screen to determine whether cracks exist inside the enclosure and to ascertain the location and size of the cracks.
[0004] However, in actual testing environments, external lighting conditions are complex and variable. When strong light shines directly onto the display screen, it produces significant reflections, making the ultrasonic waveforms and test data displayed on the screen blurry. Operators find it difficult to accurately identify and analyze waveform characteristics, thus hindering accurate judgment of crack conditions in the die-cast aluminum enclosure. This greatly affects testing efficiency and accuracy, failing to meet the urgent need for high-quality testing in industrial production. Therefore, a crack detection device for die-cast aluminum enclosures is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A device for detecting cracks in die-cast aluminum enclosures includes an ultrasonic flaw detector. A display screen is fixedly connected to one side of the ultrasonic flaw detector, and a shielding component is provided on the outer wall of the display screen. A connecting line is fixedly connected to the top of the ultrasonic flaw detector, and a placement box is fixedly connected to the other side of the ultrasonic flaw detector.

[0012] Both sides of the sunshade are fixedly connected to fixing rings. The inner wall of each fixing ring is slidably connected to the outer wall of the clip. Each clip is fixedly connected to a connecting ring on its outer wall. Multiple connecting rings are slidably connected to the inner wall of the sunshade. Each clip has a handle fixedly connected to one end, and the other end of each clip engages with the inner wall of the clip groove on each side.
[0013] As a further description of the above technical solution:
[0014] Each of the card strips is provided with a second spring on its outer wall. One end of each second spring is fixedly connected to the outer wall of the connecting ring, and the other end of each second spring is fixedly connected to the outer wall of the fixing ring. The outer wall of the ultrasonic flaw detector is fixedly connected with a plurality of protective pads in a rectangular array.
[0015] As a further description of the above technical solution:
[0016] The fixing assembly includes multiple clamps, and four adjacent clamps are combined to form a circular tube, with the inner wall of each circular tube fitting against the outer wall of the probe.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the light on one side of the display screen is blocked by rotating the sunshade, and the angle of the sunshade is fixed by the positioning component, which achieves a good viewing effect for the user on the surface of the display screen.

This solves the problem that traditional equipment usually requires the use of multiple different probes according to different usage scenarios. After the equipment is used, these multiple probes are usually left aside and are easily bumped or stepped on by surrounding staff, resulting in damage. This enhances the equipment's good storage effect for multiple different probes. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 , Figure 5 and Figure 6This utility model provides an embodiment of a device for detecting cracks in die-cast aluminum housings, comprising an ultrasonic flaw detector 1. When the ultrasonic flaw detector 1 is in operation, a suitable detection component is first selected and securely connected to the connecting component via threads, bayonets, or other means. The flaw detector is calibrated, and detection parameters are set. Then, after applying a coupling agent to the detection component, it is brought into close contact with the surface of the workpiece being inspected. Ultrasonic waves are transmitted to the workpiece through the detection component and generate reflected echoes upon encountering defects. Finally, the flaw detector receives the echo signals and displays them on a display component. Based on the waveform characteristics, position, and amplitude, the presence, size, shape, and location of defects are determined. This is prior art and will not be described in detail here. A display screen 9 is fixedly connected to one side of the ultrasonic flaw detector 1, and a shielding assembly is provided on the outer wall of the display screen 9. The ultrasonic flaw detector 1 is equipped with a shielding component to block external light from directly shining on the surface of the display screen 9, thereby improving the user's viewing clarity. The top of the ultrasonic flaw detector 1 is fixedly connected to a connecting cable 2, which is used to connect the probe 3 to the ultrasonic flaw detector 1 to realize the signal transmission function. The other side of the ultrasonic flaw detector 1 is fixedly connected to a storage box 4, which is used to store probes 3 of various specifications to prevent the probes 3 from being scattered and damaged. The storage box 4 contains multiple probes 3, one of which is threaded to one end of the connecting cable 2. The outer wall of the multiple probes 3 is equipped with a fixing component, which is used to clamp and fix probes 3 of different diameters to ensure storage stability. A sunshade component is provided on one side of the display screen 9, which is used to adjust the sunshade angle to adapt to different lighting environments.
[0036] The sunshade assembly includes a sunshade 13 located on one side of the display screen 9. The sunshade 13 blocks direct sunlight and prevents glare from the display screen 9. A fixing plate 10 is fixedly connected to one side of the ultrasonic flaw detector 1. The fixing plate 10 supports the sunshade 13 and provides a rotation fixing point. Multiple hinges 11 and annular fixing blocks 12 are fixedly connected to one side of the fixing plate 10. The hinges 11 enable the rotation of the sunshade 13 and adjust the sunshade angle. Multiple annular fixing blocks 12 are fixedly connected to the outer wall of the ultrasonic flaw detector 1. 2 provides a slot 19 structure to cooperate with the locking strip 16 to achieve a positioning function. Multiple hinges 11 are fixedly connected to the top of the sun visor 13 at their bottom. A positioning component is provided inside the sun visor 13 to fix the position of the sun visor 13 and prevent it from moving at will. The positioning component includes two locking strips 16, which are slidably connected inside the sun visor 13. The locking strips 16 are used to cooperate with the slot 19 to achieve the locking function of the sun visor 13. Each annular fixing block 12 has multiple slots 19 inside to accommodate the locking strips 16. To achieve multi-angle positioning, fixing rings 18 are fixedly connected to both sides of the interior of the sun visor 13. The fixing rings 18 are used to limit the movement range of the locking strip 16 and ensure sliding stability. The inner wall of each fixing ring 18 is slidably connected to the outer wall of the locking strip 16. A connecting ring 15 is fixedly connected to the outer wall of each locking strip 16. The connecting ring 15 is used to connect the locking strip 16 to the spring 17 and transmit the elastic force. Multiple connecting rings 15 are slidably connected to the inner wall of the sun visor 13. A handle 14 is fixedly connected to one end of each locking strip 16. The handle 14 is used to manually pull the locking strip 16. To facilitate adjustment of the angle of the sunshade 13, the other end of each clip 16 engages with the inner wall of each side slot 19. Each clip 16 has a spring 17 on its outer wall, which provides elasticity to allow the clip 16 to automatically reset and engage with the slot 19. One end of each spring 17 is fixedly connected to the outer wall of the connecting ring 15, and the other end of each spring 17 is fixedly connected to the outer wall of the fixing ring 18. Multiple protective pads 20 in a rectangular array are fixedly connected to the outer wall of the ultrasonic flaw detector 1. The protective pads 20 are used to buffer external impacts and protect the equipment casing.
[0037] Reference Figures 2-4The fixing assembly includes multiple clamping plates 8, which are used to clamp the probe 3 and are adapted to different diameter specifications. Four adjacent clamping plates 8 are combined to form a circular tube. The inner wall of each circular tube is in contact with the outer wall of the probe 3. The inner wall of each circular tube has a structure that is larger at the top and smaller at the bottom. The structure of the inner wall of the circular tube facilitates the sliding of the probe 3 and its automatic centering and fixing. A slider 7 is fixedly connected to one side of each clamping plate 8. The slider 7 is used to drive the clamping plate 8 to move and realize clamping or releasing actions. A connecting block 5 is slidably connected to the outer wall of each slider 7. The connecting block 5 is used to fix the sliding trajectory of the slider 7 and ensure the stability of movement. Multiple connecting blocks 5 are fixedly connected to the inner wall of the placement box 4 on one side. A spring 6 is set inside each connecting block 5. The spring 6 is used to provide clamping force to ensure that the probe 3 is fixedly fixed. One end of each spring 6 is fixedly connected to the outer wall of the slider 7, and the other end of each spring 6 is fixedly connected to the inner wall of the connecting block 5.
[0038] Working principle: During the use of the device, pulling the handles 14 on both sides to move them to opposite sides causes the locking strip 16 to separate from the inner wall of the slot 19. As the locking strip 16 moves, it pushes the connecting ring 15 to slide on the inner wall of the sunshade 13 and compresses the second spring 17. Next, it pushes the sunshade 13 to rotate around the hinge 11 and slide on the outer wall of the annular fixing block 12. When the sunshade 13 rotates to a suitable angle, the pulling force on the handles 14 is released. The rebound force of the second spring 17 pushes the locking strip 16 on the inner wall of the connecting ring 15 to move to the inner wall of the slot 19, thus fixing the position of the sunshade 13. The sunshade 13 blocks the light from one side of the display screen 9, preventing the light from directly shining on the outer wall of the display screen 9 and affecting the user's viewing. This achieves a good viewing effect for the user on the surface information of the display screen 9, solving the problem of strong light shining on the outer wall of the display screen 9 during the use of traditional devices, causing reflection and affecting the user's viewing. This enhances the sunshade effect of the device.
[0039] During the placement of various probes 3, the probes 3 are moved to the inner wall of the clamping plate 8. Utilizing the circular inner wall structure formed by four adjacent clamping plates 8, which has a larger diameter at the top and a smaller diameter at the bottom, the probes 3 can be moved along the inner wall of the clamping plate 8 into the placement box 4. As the probes 3 move along the inner wall of the clamping plate 8, their outer walls push the slider 7 to slide on the inner wall of the connecting block 5, compressing the spring 6. The elasticity of the spring 6 provides movement space for the clamping plate 8, ensuring it can accommodate probes 3 of different sizes. Furthermore, the rebound force of the spring 6 pushes the clamping plate 8 through the slider 7 to clamp and fix the outer wall of the probe 3, ensuring that the position of the probes 3 remains fixed during placement. This achieves a good placement effect for different probes 3, solving the problem that traditional equipment often requires the use of multiple probes 3 depending on the usage scenario, and after the equipment is used, these probes 3 are usually left lying around, easily bumped or stepped on by surrounding staff, leading to damage. This enhances the equipment's ability to store multiple probes 3 effectively.
