[0032] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0033] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or alternative features having similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0034] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0035] In this embodiment, a cleaning structure is proposed, which is used for ultrasonic cleaning of the test piece, and can fix the test piece during the cleaning process to prevent the test piece from vibrating due to ultrasonic cleaning, thereby preventing the test piece from expanding the crack size of the crack points on it due to long-term vibration. The test piece in this embodiment can specifically be a five-point test piece for fluorescent penetration testing of the workpiece, and five crack points for detection are set on the five-point test piece. Among them, the detection principle of the five-point test piece is a common detection principle in the prior art, which will not be described in detail here, and the workpiece can specifically be a turbine of an aircraft engine.

[0036] Specifically, Figures 1 to 3 As shown, the cleaning structure includes a cleaning tank 1 and a fixing assembly 2; wherein the cleaning tank 1 is used for ultrasonic cleaning of the test strip 3 so as to ensure the cleaning effect on the test strip 3 without damaging the test strip 3; the fixing assembly 2 includes a frame 21 and a clamping member 22, a part of the frame 21 is supported on a workbench 4 outside the cleaning tank 1, and the remaining part of the frame 21 is located in the cleaning tank 1, and the clamping member 22 is installed on the part of the frame 21 located in the cleaning tank 1, and the clamping member 22 is used to clamp and fix the test strip 3 to the cleaning tank 1, and the frame 21 and the clamping member 22 are not in contact with the cleaning tank 1 respectively.

[0037] Compared with the prior art, the cleaning structure in this embodiment removes the metal material frame connected to the cleaning tank 1, and adds a fixing component 2 that is not in contact with the cleaning tank 1; a part of the frame 21 in the fixing component 2 is supported on the workbench 4 outside the cleaning tank 1, so that the entire fixing component 2 can be supported on the workbench 4, and the workbench 4 is fixedly arranged, that is, there is no need to connect the frame 21 to the cleaning tank 1 to provide support for the frame 21; at the same time, the remaining part of the frame 21 is located in the cleaning tank 1, and the clamping member 22 is installed on the part of the frame 21 located in the cleaning tank 1, and the clamping member 22 is used to clamp and fix the test piece 3 to the cleaning tank 1, so that the test piece 3 can be fixed in the cleaning tank 1 by the clamping member 22, so as to ensure the cleaning stability of the test piece 3 in the cleaning tank 1, and there is no need to place the test piece 3 in the metal material frame connected to the cleaning tank 1, that is, there is no need to It is necessary to set a metal material frame in the cleaning tank 1 so as to fix the test piece 3 in the cleaning tank 1. Compared with placing the test piece 3 on the metal material frame, the clamping member 22 can better fix the test piece 3 and prevent the test piece 3 from shaking freely in the cleaning tank 1 during the cleaning process. Moreover, since the frame 21 and the clamping member 22 are not in contact with the cleaning tank 1 respectively, during the ultrasonic cleaning process, the vibration of the cleaning tank 1 will not be transmitted to the frame 21 and the clamping member 22, and will not be transmitted to the test piece 3, which can avoid the vibration of the test piece 3 during the ultrasonic cleaning process, thereby avoiding the problem of the crack size of each crack point used for detection in the test piece 3 becoming larger under the action of long-term vibration, and then ensuring that the size of each crack point on the test piece 3 is relatively accurate, so that the detection result of the test piece 3 on the workpiece is relatively accurate.

[0038] It is worth noting that an ultrasonic generator (not shown in the figure) is provided on the cleaning tank 1, and a cleaning solution is placed in the cleaning tank 1. The ultrasonic generator can ultrasonically clean the test strip 3 through the cleaning solution. In the cleaning process, the test strip 3 is completely immersed in the cleaning solution to ensure the cleaning effect of the test strip 3. In this embodiment, the ultrasonic generator and the cleaning solution can use the ultrasonic generator and the cleaning solution commonly used in the prior art, and the specific ultrasonic cleaning principle will not be described in detail here.

[0039] Furthermore, if Figures 1 to 3 As shown, two arc-shaped avoidance grooves 211 are formed on the frame 21, and the two opposite first side plates 11 of the cleaning tank 1 are respectively located in the two arc-shaped avoidance grooves 211 with gaps therebetween, so that a part of the frame 21 can be supported on the workbench 4 outside the cleaning tank 1, and the remaining part of the frame 21 is located in the cleaning tank 1, and it can be ensured that the first side plate 11 of the cleaning tank 1 does not contact the groove edge of the arc-shaped avoidance groove 211.

[0040] By forming the arc-shaped avoidance groove 211, the frame 21 can be supported on the workbench 4 on the one hand, and the frame 21 can be arranged inside and outside the cleaning tank 1 while ensuring that the frame 21 does not contact the cleaning tank 1 on the other hand. Here, the specific size and structure of the arc-shaped avoidance groove 211 are not limited, as long as the frame 21 can be supported on the workbench 4 while ensuring that the frame 21 does not contact the cleaning tank 1.

[0041] Furthermore, if Figure 1 As shown, the portion of the frame 21 located outside the cleaning tank 1 has supporting feet 213, and four supporting feet 213 are evenly arranged on the outer circumference of the cleaning tank 1. The supporting feet 213 are supported on the workbench 4. That is, through the supporting effect of the four supporting feet 213 on the workbench 4, the entire frame 21 is stably supported on the workbench 4, and there will be no problem of tilting or shaking of the frame 21.

[0042] Specifically, a supporting foot 213 is snapped into a snap hole (not shown in the figure) on the workbench 4 so that the supporting foot 213 can be stably fixed on the workbench 4, ensuring the supporting stability of the frame 21 on the workbench 4, so that the entire frame 21 can be more stably supported on the workbench 4.

[0043] Specifically, if Figures 2 to 4 As shown, the portion of the frame 21 located in the cleaning tank 1 is formed with upper and lower multiple mounting layers 212, one mounting layer 212 is used to mount at least one clamp 22, and the bottom end surface of the mounting layer 212 located at the bottom layer is higher than the inner bottom end surface of the cleaning tank 1, so as to ensure that the portion of the frame 21 located in the cleaning tank 1 will not contact the inner bottom end surface of the cleaning tank 1, thereby ensuring that the frame 21 will not contact the cleaning tank 1.

[0044] By providing multiple layers of mounting layers 212, ultrasonic cleaning can be performed on the test strips 3 on each mounting layer 212 at the same time, thereby improving the cleaning efficiency of the test strips 3. The test strips 3 on the topmost mounting layer 212 are completely immersed in the cleaning solution. In this embodiment, two layers of mounting layers 212 are formed on the frame 21, and the specific number of layers of the mounting layers 212 is not specifically limited.

[0045] Furthermore, by installing at least one clamping member 22 on a mounting layer 212, the test strip 3 on the same layer can be clamped and fixed by multiple clamping members 22 at the same time, so that the test strip 3 can be fixed better, thereby ensuring the stability of the test strip 3 in the cleaning tank 1. In this embodiment, Figure 4 As shown, one clamping member 22 is installed on one installation layer 212. In other embodiments, two or three clamping members 22 may be installed in one installation layer 212, which is not specifically limited here.

[0046] Furthermore, if Figures 1 to 4 As shown, the width of the frame 21 is smaller than the spacing between the two second side panels 12 of the cleaning tank 1, so as to ensure that the portion of the frame 21 located in the cleaning tank 1 will not contact the second side panels 12, thereby ensuring that the entire frame 21 will not contact the cleaning tank 1. The two first side panels 11 and the two second side panels 12 are connected to form a frame structure, and the bottom end of the frame structure is connected to the tank bottom panel 13, so that the tank bottom panel 13, the two first side panels 11 and the two second side panels 12 can be connected to form a complete cleaning tank 1. The width direction of the frame 21 is as follows: Figure 1 and Figure 4 As shown by arrow A in FIG.

[0047] Specifically, Figure 4 and Figure 5 As shown, the clamping member 22 includes a supporting base plate 221 and a clamping body 222; wherein, the opposite ends of the supporting base plate 221 are respectively mounted to the mounting layer 212, and the bottom end surface of the supporting base plate 221 on the bottom layer is higher than the inner bottom end surface of the tank bottom plate 13 of the cleaning tank 1, so that the clamping member 22 does not contact the cleaning tank 1; a clamping body 222 is provided on at least one end of the supporting base plate 221, and the clamping body 222 is used to rotate and press the test piece 3 onto the supporting base plate 221, so as to be able to clamp and fix the test piece 3 between the supporting base plate 221 and the clamping body 222. Among them, the side of the test piece 3 where the crack point is provided faces the supporting base plate 221, so as to prevent the clamping body 222 from damaging the crack point on the test piece 3 during the pressing process; and the supporting base plate 221 does not cover the crack point, so as to expose the crack point on the test piece 3 to facilitate cleaning of the crack point, and at the same time, it can prevent the crack point on the test piece 3 from being damaged by the supporting base plate 221.

[0048] In this embodiment, Figure 4 and Figure 5 As shown, clamping bodies 222 are respectively provided at the opposite ends of the supporting base plate 221, that is, two clamping bodies 222 are respectively provided on one supporting base plate 221, so that the test piece 3 can be clamped and fixed at the same time by the two relatively arranged clamping bodies 222, so as to ensure that the clamping member 22 has a better clamping and fixing effect on the test piece 3.

[0049] It is worth mentioning that the support base plate 221 can also be set as a hollow structure. On the one hand, it can ensure the supporting effect of the support base plate 221 on the test piece 3. On the other hand, the hollow structure can make the support base plate 221 and the crack point on the test piece 3 staggered, thereby ensuring that the crack point on the test piece 3 can be exposed.

[0050] Specifically, if Figure 5As shown, the clamping body 222 includes a main body 2221, abutment 2222, a pressure head 2223 and a handle 2224; wherein the main body 2221 is mounted on the supporting base plate 221, one end of the abutment 2222 is rotatably mounted on the main body 2221, and the pressure head 2223 is mounted to the other end of the abutment 2222; the handle 2224 is rotatably connected to the main body 2221 and is linked to the abutment 2222; when the handle 2224 is rotated forward, the handle 2224 can drive the abutment 2222 to rotate relative to the main body 2221, so as to drive the pressure head 2223 to rotate to press the test strip 3; when the handle 2224 is rotated backward, the handle 2224 can drive the abutment 2222 to rotate in the opposite direction, so as to drive the pressure head 2223 to rotate in the opposite direction to move away from the test strip 3, so as to facilitate the test strip 3 to be taken out from between the supporting base plate 221 and the pressure head 2223 after cleaning.

[0051] It is worth noting that the clamping body 222 in this embodiment is a common clamping structure in the prior art, and the specific clamping principle of the clamping body 222 will not be described in detail here, and reference may be made to the clamping principle of the existing clamping structure.

[0052] Furthermore, a buffer (not shown) is provided on the pressing head 2223 so that the buffer is pressed against the test strip 3, so as to provide a buffering effect for the test strip 3, thereby better protecting the test strip 3. The buffer can be made of plastic or elastic material.

[0053] Specifically, Figure 4 and Figure 5 As shown, the main body 2221 in the clamping body 222 can slide along the length direction of the supporting base plate 221 and stop at any position, so as to be able to adjust the installation position of the entire clamping body 222 on the supporting base plate 221, so that the test pieces 3 of various sizes can be clamped and fixed by the clamping body 222, so that the versatility and applicability of the entire cleaning structure are better. Among them, the length direction of the supporting base plate 221 is parallel to the width direction of the frame 21, that is, the length direction of the supporting base plate 221 is also shown by the arrow A in the figure.

[0054] It is worth noting that a slide rail and slider structure can be provided between the support base plate 221 and the main body 2221 to provide a guide for the sliding of the main body 2221 on the support base plate 221, thereby ensuring the guidance and stability of the sliding of the main body 2221 on the support base plate 221; when the main body 2221 slides to a suitable position on the support base plate 221, the main body 2221 and the support base plate 221 can be fixed by a limiting member to limit the installation position of the main body 2221 on the support base plate 221, so that the clamping body 222 can stop at any position on the support base plate 221. The limiting member can specifically be a limiting bolt.

[0055] Furthermore, if Figure 4 and Figure 5 As shown, the support base plate 221 can be slidably installed on the installation layer 212 along the length direction perpendicular to the support base plate 221 and stop at any position, so as to be able to adjust the setting position of the clamping body 222 in the frame 21, so that the clamping body 222 can be clamped and fixed to different positions on the test piece 3. On the one hand, it can help the support base plate 221 avoid the crack point on the test piece 3, and on the other hand, it can clamp and fix the test piece 3 from different positions to ensure a better clamping and fixing effect on the test piece 3. Among them, the length direction perpendicular to the support base plate 221 is specifically as follows: Figure 4 As shown by arrow B in FIG.

[0056] It is worth mentioning that a guide rail and guide block structure can be set between the support base plate 221 and the frame 21 to provide a guiding effect for the sliding of the support base plate 221 on the frame 21, thereby ensuring the guidance and stability of the support base plate 221 sliding on the mounting layer 212 of the frame 21; when the support base plate 221 slides to a suitable position on the frame 21, the support base plate 221 and the frame 21 can be fixed by limiting bolts to limit the installation position of the support base plate 221 on the mounting layer 212, so that the support base plate 221 can be stopped at any position on the mounting layer 212 of the frame 21.

[0057] Furthermore, the materials of the frame 21 and the clamp 22 are both alkali-resistant metal materials. Since the cleaning solution in the cleaning tank 1 is a weakly alkaline solution, the frame 21 and the clamp 22 can be prevented from being corroded or reacting in the cleaning solution. On the one hand, the service life of the frame 21 and the clamp 22 can be improved. On the other hand, the part of the frame 21 or the clamp 22 that is corroded by the cleaning solution can be prevented from affecting the cleaning effect of the test piece 3.

[0058] Furthermore, by making the frame 21 and the clamp 22 made of metal, the weight of the frame 21 and the clamp 22 can be increased, so that the stability and strength of the frame 21 and the clamp 22 are better, thereby ensuring the supporting stability of the frame 21 on the workbench 4 and ensuring the clamping strength of the clamp 22 on the test piece 3.

[0059] Among them, in order to ensure the cleaning effect of the cleaning solution on the test strip 3, the cleaning solution needs to be heated; therefore, in this embodiment, the material of the frame 21 and the clamping member 22 immersed in the cleaning solution is a material that can withstand a certain temperature, that is, the material of the frame 21 and the clamping member 22 is an alkali-resistant and high-temperature resistant metal material, specifically, it can be stainless steel.

[0060] The specific working process of the cleaning structure in this embodiment is as follows:

[0061] First, add 5% concentration of magnetic flux 282 cleaning agent into the cleaning tank 1 to form a cleaning solution, and add it to 60%-70% of the total capacity of the entire cleaning tank 1 to ensure that the cleaning solution completely submerges the test piece 3; then open the cleaning tank 1 and heat it to 40°C.

[0062] Then, the support base plate 221 is mounted to a suitable position on the mounting layer 212 of the frame 21, and the test piece 3 is placed on the support base plate 221. At the same time, the handle 2224 is rotated forward to drive the abutment member 2222 to rotate relative to the main body 2221, so as to drive the pressing head 2223 on the abutment member 2222 to rotate to press the test piece 3, so as to clamp and fix the test piece 3 between the support base plate 221 and the pressing head 2223 of the clamping body 222, and the surface of the test piece 3 with the crack point faces the support base plate 221, and the support base plate 221 avoids the crack point on the test piece 3. If two test pieces 3 need to be cleaned at the same time, one test piece 3 can be clamped and fixed on the clamping members 22 in the two mounting layers 212 respectively.

[0063] Finally, place the fixed component 2 and the test strip 3 thereon as a whole into the cleaning tank 1, and the frame 21 and the clamping member 22 in the fixed component 2 are not in contact with the cleaning tank 1; then turn on the ultrasonic generator to ultrasonically clean the test strip 3 for 30 minutes. After the cleaning is completed, take out the entire fixed component 2 and the test strip 3 thereon from the cleaning tank 1, and then remove the test strip 3 from the clamping member 22, and observe whether the test strip 3 is cleaned under a black light. If cleaned, rinse the entire fixed component 2 and the test strip 3 with clean water and store them as required. If not cleaned, repeat the above cleaning steps until they are cleaned.

[0064] The cleaning structure in this embodiment replaces the metal material frame in the prior art by adding a fixing component 2; by making the two opposite first side panels 11 of the cleaning tank 1 respectively positioned in the two arc-shaped avoidance grooves 211 on the frame 21, a part of the frame 21 is supported on the workbench 4 outside the cleaning tank 1, and the remaining part of the frame 21 is positioned in the cleaning tank 1, and it can be ensured that the first side panel 11 of the cleaning tank 1 does not contact the groove edge of the arc-shaped avoidance groove 211; at the same time, the width of the frame 21 is made smaller than the spacing between the two opposite second side panels 12 of the cleaning tank 1, so as to ensure that the part of the frame 21 located in the cleaning tank 1 does not contact the second side panel 12; and the bottom end surface of the mounting layer 212 located at the bottom layer is higher than the inner bottom end surface of the tank bottom plate 13 of the cleaning tank 1, so as to ensure that the part of the frame 21 located in the cleaning tank 1 does not contact the tank bottom plate 13 of the cleaning tank 1; thereby, it can be ensured that the frame 21 in the fixing component 2 does not contact the cleaning tank 1.

[0065] At the same time, by making the bottom end surface of the supporting bottom plate 221 located on the bottom layer higher than the inner bottom end surface of the tank bottom plate 13 of the cleaning tank 1, the supporting bottom plate 221 is not in contact with the cleaning tank 1; and the clamping body 222 is arranged on the supporting bottom plate 221 to ensure that the entire clamping member 22 is not in contact with the cleaning tank 1; so that the entire fixing assembly 2 is not in contact with the cleaning tank 1, thereby preventing the vibration of the cleaning tank 1 from being transmitted to the frame 21 and the clamping member 22 during the ultrasonic cleaning process, and thus ensuring that the vibration of the cleaning tank 1 will not be transmitted to the test piece 3, thereby preventing the test piece 3 from vibrating during the ultrasonic cleaning process, thereby preventing the crack size of each crack point used for detection in the test piece 3 from becoming larger due to long-term vibration.

[0066] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
