[0002] In the automotive manufacturing and repair field, the turbine shaft is a key component of the automotive turbocharger, and its internal quality directly affects the performance and reliability of the turbocharger. Currently, existing flaw detection devices have some shortcomings when inspecting automotive turbine shafts. The poor fit between the detection head and the turbine shaft surface leads to unstable detection signals, affecting the accuracy of the detection results. The devices also have poor protective performance, making them susceptible to intrusion from external dust, oil, and other impurities, which reduces the service life of the detection devices. Therefore, a new type of automotive turbine shaft flaw detection device is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a novel flaw detection device for automotive turbine shafts, which has the advantage of good sealing performance in flaw detection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel flaw detection device for automotive turbine shafts, comprising a flaw detector body, a detection head fixedly mounted on the left end of the flaw detector body, a fixed frame sleeved on the outer side of the left end of the flaw detector body, the fixed frame being composed of two parts, with the right side connecting part connected by a connecting plate and screws, fixed brackets mounted on both the upper and lower sides of the fixed frame, support springs fixedly mounted on both sides of the right end of the inner cavity of the fixed bracket, and a fixed seat fixedly mounted on the left end of the support spring, with an elastic sealing plate embedded in the left end of the fixed seat, the two elastic sealing plates being distributed in a trumpet shape outside the detection head.

[0005] As a preferred embodiment, side sealing gaskets are bonded to the front and rear sides of the elastic sealing plate and between adjacent sides. The side sealing gaskets are made of elastic material, and rubber struts are installed on the bent portion of the elastic sealing plate.

[0006] As a preferred embodiment, the fixed base has a horizontally open movable groove inside, and a telescopic limiting plate is telescopically installed inside the movable groove. The right end of the telescopic limiting plate is connected to the right side of the inner cavity of the fixed frame.

[0007] As a preferred embodiment, guide rods are fixedly installed on both the front and rear sides of the fixed frame, and a sealing cover is snapped onto the outside of the guide rod. The outer end of the sealing cover covers the outside of the fixed frame, and the sealing cover adopts a lateral movement design outside the fixed frame.

[0008] As a preferred embodiment, a grip protective cover is fitted onto the outside of the right end of the flaw detector body, and the surface of the grip protective cover is provided with an arc-shaped groove.

[0009] As a preferred embodiment, the end of the detection head has an arc-shaped structure, and the surface of the detection head is provided with a wear-resistant layer, the wear-resistant layer being a ceramic coating.

[0010] As a preferred embodiment, the connecting plate has multiple evenly distributed threaded holes, through which screws pass to tightly connect the two parts of the fixing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a two-part fixed frame that is sleeved on the outside of the flaw detector. This not only facilitates installation and disassembly but also allows for flexible adjustment according to actual needs, greatly improving the convenience of use. The fixed brackets on the upper and lower sides of the fixed frame are ingeniously designed. The support springs and the fixed seats connected to them in the inner cavity can play a good role in buffering and fixing during the use of the flaw detector, reducing the impact of factors such as vibration on the flaw detector body and detection head, and ensuring the stability and accuracy of the detection. The trumpet-shaped distribution of the elastic sealing plate helps to better fit the detection part, enhancing the detection effect and reliability, so that the flaw detector can perform well in complex environments and different detection scenarios.

[0013] 2. This utility model provides a stable foundation for the installation and movement of the sealing cover by guide rods installed on the front and rear sides of the fixed frame. The outer end of the sealing cover can cover the outside of the fixed frame, further enhancing the protection of the critical components inside the flaw detector. In addition, the sealing cover adopts a lateral movement design outside the fixed frame. This design gives the operator great operational flexibility. During the use of the flaw detector, if it is necessary to inspect, maintain or adjust the components inside the fixed frame, simply move the sealing cover laterally to quickly open the protected area. After the operation is completed, the sealing cover can be moved back to its original position to restore the protective state. There is no need for a cumbersome disassembly and installation process, which improves work efficiency. Attached Figure Description

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.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0021] Please see Figure 1 As shown, this utility model provides a novel flaw detection device for automotive turbine shafts, including a flaw detector body 1. A detection head 2 is fixedly installed on the left end of the flaw detector body 1. A fixing frame 3 is sleeved on the outside of the left end of the flaw detector body 1. The fixing frame 3 is composed of two parts, and the connecting part on the right side is connected by a connecting plate 4 and screws. Fixing brackets 7 are installed on both the upper and lower sides of the fixing frame 3. Support springs 8 are fixedly installed on both sides of the right end of the inner cavity of the fixing bracket 7. A fixing seat 9 is fixedly installed on the left end of the support spring 8. An elastic sealing plate 5 is embedded on the left end of the fixing seat 9. The two elastic sealing plates 5 are distributed in a trumpet shape on the outside of the detection head 2.

[0022] This technical solution uses a two-part fixed frame 3 that is fitted onto the outside of the flaw detector. This not only facilitates installation and disassembly but also allows for flexible adjustment according to actual needs, greatly improving ease of use. The fixed brackets 7 on the upper and lower sides of the fixed frame 3 are ingeniously designed. The support springs 8 and the fixed seats 9 connected to them in their inner cavities can play a good role in buffering and fixing the flaw detector during use, reducing the impact of factors such as vibration on the flaw detector body 1 and the detection head 2, and ensuring the stability and accuracy of the detection. The trumpet-shaped distribution of the elastic sealing plate 5 helps to better fit the detection part, enhancing the detection effect and reliability, so that the flaw detector can perform well in complex environments and different detection scenarios. Example

[0023] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, the elastic sealing plate 5 has side sealing gaskets 6 bonded to its front and rear sides and adjacent to each other. The side sealing gaskets 6 are made of elastic material. The bent part of the elastic sealing plate 5 is equipped with a rubber support rod 13. The fixed base 9 has a movable groove opened laterally inside, and a telescopic limiting plate 10 is telescopically installed inside the movable groove. The right end of the telescopic limiting plate 10 is connected to the right side of the inner cavity of the fixed frame 7.

[0024] Adopting such Figure 1 The technical solution shown features side sealing gaskets 6 bonded to the front and rear sides of the elastic sealing plate 5, made of elastic material, which further enhances the sealing effect and better adapts to different testing environments, preventing foreign matter intrusion. Simultaneously, the rubber support rods 13 installed on the bent portion of the elastic sealing plate 5 provide additional support, ensuring it maintains a good sealing state while preventing deformation due to external forces, thus improving the overall structural reliability. The right end of the telescopic limiting plate 10 is connected to the right side of the inner cavity of the fixed frame 7. This structure allows the fixed seat 9 to be effectively constrained by the telescopic limiting plate 10 when moving under the action of the support spring 8, preventing excessive displacement and ensuring the relative position stability between the components during the operation of the flaw detector, thereby improving the overall performance and testing accuracy of the flaw detector.

[0025] Secondly, in the technical solution, guide rods 11 are fixedly installed on both the front and rear sides of the fixed frame 3. A sealing cover 12 is snapped onto the outside of the guide rods 11. The outer end of the sealing cover 12 covers the outside of the fixed frame 7, and the sealing cover 12 adopts a lateral movement design outside the fixed frame 3. A grip protective cover 14 is sleeved on the outside of the right end of the flaw detector body 1. The surface of the grip protective cover 14 is provided with an arc-shaped groove.

[0026] Its adoption is as follows Figure 1 The technical solution shown provides a stable base for the installation and movement of the sealing cover 12 by the guide rods 11 installed on the front and rear sides of the fixed frame 3. The outer end of the sealing cover 12 can cover the outside of the fixed frame 7, further enhancing the protection of the key components inside the flaw detector. In addition, the sealing cover 12 adopts a lateral movement design outside the fixed frame 3. This design gives the operator great operational flexibility. During the use of the flaw detector, if it is necessary to inspect, maintain or adjust the components inside the fixed frame 7, the sealing cover 12 can be moved laterally to quickly open the protected area. After the operation is completed, the sealing cover 12 can be moved back to its original position to restore the protective state. There is no need for a cumbersome disassembly and installation process, which improves work efficiency. Example

[0027] This utility model is as follows Figures 1-4As shown, the end of the detection head 2 has an arc-shaped structure, and the surface of the detection head 2 is provided with a wear-resistant layer, which is made of ceramic coating. The connecting plate 4 has multiple evenly distributed threaded holes, and screws pass through the threaded holes to tightly connect the two parts of the fixing frame 3.

[0028] By adopting the above technical solution, the end of the detection head 2 has an arc-shaped structure, which can better conform to the surface of various shaped objects during flaw detection. Whether it is a curved surface, a spherical surface, or an irregular surface, the arc-shaped end can make good contact with it, avoiding the problem of blind spots or inaccurate detection caused by mismatch between the detection head 2 and the surface of the object being inspected. This effectively improves the applicability and detection effect of the flaw detector.

[0029] The ceramic coating on the surface of the detection head 2 has extremely high hardness and wear resistance. During long-term detection, the detection head 2 will inevitably rub and collide with the surface of the object being detected. The ceramic coating can effectively resist this wear and maintain the flatness and smoothness of the surface of the detection head 2. This helps to ensure the stable transmission of detection signals, improve the accuracy and reliability of detection, and also reduces the need for frequent replacement due to wear of the detection head 2, thus reducing the cost of use.

[0030] The working principle of this utility model is as follows: When using this novel flaw detection device for automotive turbine shafts, the operator holds the ergonomically designed grip cover 14 with an arc-shaped groove, picks up the flaw detector body 1, and brings the detection head 2, which has an arc-shaped end and a ceramic coating on its surface, close to or in contact with the automotive turbine shaft. The flaw detector body 1 emits an electrical signal, which is converted into an ultrasonic signal by the detection head 2 and transmitted to the turbine shaft. When the ultrasonic wave encounters an internal defect and is reflected back, the detection head 2 converts it back into an electrical signal and transmits it back to the body for analysis to determine the defect. During the detection process, the trumpet-shaped distribution of the elastic sealing plate 5 helps to better fit the detection area, and it moves telescopically through the cooperation of the support spring 8 and the fixed seat 9, ensuring that the entire flaw detection process is accurate, stable, and reliable.
