DETAILED DESCRIPTION

[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0031] In the present application, unless otherwise specified, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of the components themselves, but the above orientation words are not used to limit the present application.

[0032] In order to solve the problem of long pretreatment time in the prior art, the present application provides an acoustic emission detection pretreatment auxiliary device and an acoustic emission detection pretreatment method.

[0033] As Figures 1 to 6 shown, the acoustic emission detection pretreatment auxiliary device comprises a box 10, a driving structure 20, a cutting structure 30 and a polishing device 40, the box 10 has a containing cavity 11, the box 10 has a first opening 12 and a second opening 13 communicating with the containing cavity 11, the plane where the first opening 12 is located is perpendicular to the plane where the second opening 13 is located; the driving structure 20 is arranged in the box 10 and connected with the top surface of the box 10, the first opening 12 is arranged opposite to the top surface; the cutting structure 30 is detachably connected with the driving structure 20, at least a part of the driving structure 20 extends out of the first opening 12 and contacts with the structure to be processed, the driving structure 20 drives the cutting structure 30 to move to cut the structure to be processed; the polishing device 40 is detachably connected on the driving structure 20, at least a part of the polishing device 40 is located at the first opening 12, the driving structure 20 drives the polishing device 40 to move to polish the structure to be processed.

[0034] By setting the cutting structure 30, the acoustic emission detection pretreatment auxiliary device can cut the heat preservation layer on the structure to be processed, so as to facilitate the polishing of the surface of the metal after the heat preservation layer is cut off. The setting of the polishing device 40 can polish the surface of the structure to be processed until the surface of the structure to be processed exposes the metal luster. The setting of the driving structure 20 can drive the cutting structure 30 to move, so that the cutting structure 30 can cut the structure to be processed at different positions. The driving structure 20 can drive the polishing device 40 to move to polish the surface of the structure to be processed until the surface of the structure to be processed is polished to expose the metal luster. At least a part of the polishing device 40 is exposed at the first opening 12, so that the exposed part polishes the structure to be processed.

[0035] It should be noted that the polishing device 40 and the cutting structure 30 can be installed on the driving structure 20 at the same time when they are not working, and the polishing device 40 or the cutting structure 30 can be selectively worked when the acoustic emission detection pretreatment auxiliary device works. The polishing device 40 and the cutting structure 30 are main wear parts, and the polishing device 40 and the cutting structure 30 are set in a detachable form with the driving structure 20, which facilitates the replacement of the polishing device 40 and the cutting structure 30, and can greatly reduce the production cost.

[0036] As shown in Figure 1 , Figure 3 and Figure 5 , the box body 10 is provided with a sliding groove 14 on the top surface and the opposite two side surfaces, and at least a part of the cutting structure 30 extends into the sliding groove 14, so that the cutting structure 30 slides along the sliding groove 14. The cutting structure 30 can slide along the sliding groove 14 to ensure the stability of the cutting structure 30 in working and avoid other structural parts from forming a stop to the cutting structure 30.

[0037] As shown in Figures 1 to 5 , the cutting structure 30 comprises a transmission structure 31, a connecting structure 32 and a cutting knife 33, the transmission structure 31 is drivingly connected with the driving structure 20; the transmission structure 31 is connected with the connecting structure 32 to drive the connecting structure 32 to move along the sliding groove 14; the cutting knife 33 is connected with the connecting structure 32 and at least a part of the cutting knife 33 extends out of the first opening 12 to cut the heat preservation layer on the structure to be processed. The transmission structure 31 is connected with the driving structure 20, so that the driving structure 20 can drive the transmission structure 31 to move, and the transmission structure 31 drives the connecting structure 32 to slide in the sliding groove 14, and the connecting structure 32 drives the cutting knife 33 to move to cut the heat preservation layer on the surface of the structure to be processed.

[0038] Specifically, the box 10 is a double-layer structure, and the double-layer structure has a sandwich layer. When the cutting structure 30 is located in the chute 14, the cutting knife 33 is located in the sandwich layer on the side of the chute 14. The sandwich layer provides a placement space for the cutting knife 33. When the cutting knife 33 is not in use, the cutting knife 33 is located in the sandwich layer, thereby avoiding the loss of the cutting knife 33. At the same time, the movement of the cutting knife 33 in the sandwich layer can effectively avoid the cutting knife 33 from cutting people or cutting structural parts during cutting. This arrangement makes one side of the cutting knife 33 exposed and in contact with the structure to be processed, thereby reducing the risk of the cutting knife 33 cutting people and increasing the stability and safety of the cutting knife 33.

[0039] As shown in Figure 1 , Figure 3 and Figure 5 , the chute 14 is a notch arranged on the side surface of the box 10, and the connecting structure 32 is a connecting plate. Both ends of the connecting plate extend out of the side surface of the box 10. This arrangement can ensure the contact area between the connecting plate and the chute 14, thereby avoiding the connecting plate from being pulled out of the chute 14 and increasing the stability of the connecting structure 32. At the same time, this arrangement can also manually push the connecting structure 32 to move, thereby increasing the versatility of the acoustic emission detection pretreatment auxiliary device.

[0040] As shown in Figure 6 , the polishing device 40 is provided with a polishing structure 41 on the surface away from the driving structure 20. The polishing structure 41 can increase the polishing efficiency of the structure to be processed, so that the polishing device can quickly polish the structure to be processed.

[0041] Optionally, the polishing structure 41 is a protrusion or a convex rib. The protrusion or convex rib is arranged on the surface of the polishing device 40 away from the driving structure 20, so that the surface is uneven, thereby increasing the polishing efficiency of the polishing device 40.

[0042] Specifically, the polishing structure 41 is a cross-shaped polishing edge, which plays a role in polishing the surface of the metal. However, the specific shape of the polishing structure is not limited to a cross shape, but can also be other shapes, such as a mesh shape, a V shape, an N shape, etc.

[0043] As shown in Figures 1 to 3 , the driving structure 20 includes a driving motor 21 and a transmission gear 22. The driving motor 21 is connected to the top surface. The driving motor 21 is connected to the transmission gear 22 to drive the transmission gear 22 to rotate. The output shaft of the driving motor 21 is connected to the transmission gear 22. When the driving motor 21 works, the output shaft drives the transmission gear 22 to rotate.

[0044] As shown in Figures 3 to 5As shown, the transmission structure 31 of the cutting structure 30 is a rack, which meshes with the transmission gear 22. The drive motor 21 rotates to drive the rack to make linear motion. The rack meshes with the transmission gear 22, and when the transmission gear 22 rotates, it drives the rack to make linear motion, thereby causing the cutting blade 33 to cut along a straight line.

[0045] like Figure 3 As shown, the connecting structure 32 of the cutting structure 30 is located at the second opening 13, and the rack extends from the second opening 13. The second opening 13 prevents the side wall of the housing 10 from blocking the rack, increases the range of motion of the rack, and increases the cutting distance of the cutting blade 33. At the same time, the connecting structure 32 is located at the second opening 13, which can be manually pushed to make the cutting blade 33 cut the structure to be processed, increasing the versatility of the acoustic emission detection pretreatment auxiliary device.

[0046] like Figure 1 As shown, the grinding device 40 is connected to the transmission gear 22, and the transmission gear 22 drives the grinding device 40 to rotate. The transmission gear 22 drives the grinding device 40 to rotate so that the grinding device 40 can be stably ground in one position to grind the structure to be treated, and can quickly form an area with exposed metallic luster on the structure to be treated, and perform acoustic emission detection in this area.

[0047] The acoustic emission detection pretreatment method utilizes the aforementioned acoustic emission detection pretreatment auxiliary device. The method includes the following steps: removing the grinding device 40 from the acoustic emission detection pretreatment auxiliary device; placing the acoustic emission detection pretreatment auxiliary device on the surface of the structure to be treated; opening the drive structure 20 of the acoustic emission detection pretreatment auxiliary device; the cutting structure 30 of the acoustic emission detection pretreatment auxiliary device cuts the insulation layer on the structure to be treated in one direction, forming two cuts on the insulation layer; rotating the acoustic emission detection pretreatment auxiliary device 90 degrees; aligning the cutting blade 33 of the cutting structure 30 with the cuts; cutting the insulation layer on the structure to be treated in one direction, creating a square opening; and closing the drive structure 20; removing the cutting structure 30; installing the grinding device 40; opening the drive structure 20; and grinding the surface of the structure to be treated with the grinding device 40 until the surface of the structure to be treated reveals a metallic luster, thus completing the grinding process. This setup allows the acoustic emission detection pretreatment auxiliary device to cut a square piece of insulation from the surface of the structure to be treated, exposing the metal of the structure. The exposed metal is then polished by the polishing device 40 until the surface of the structure to be treated shows a metallic luster.

[0048] The surface polished by the electrically driven polishing rod is smoother than the surface polished by a file and sandpaper, and the accuracy of subsequent detection is ensured. The structure surface to be processed is processed more efficiently and conveniently by using the acoustic emission detection pretreatment auxiliary device. In addition, the acoustic emission detection pretreatment auxiliary device has low cost and durability, and saves manpower and resources.
