Description

Technical Field

[0001] This utility model relates to the technical field of casting inspection, and in particular to a precision casting crack detection device. Background Technology

[0002] Crack detection in castings is a crucial step in ensuring their structural integrity and operational safety. Cracks may originate from cooling stress during the casting process, material defects, or improper manufacturing processes. If not detected in time, they can propagate during subsequent machining, heat treatment, or actual pressure conditions, leading to sudden component fracture, equipment failure, or even safety accidents.

[0003] The prior art discloses a precision casting crack detection device (publication number CN217820049U), including a detection box. The outer wall of the detection box is connected to a drive rod via a drive mechanism. A liquid storage tank is fixedly connected to the top of the detection box. The interior of the liquid storage tank is connected to an "L"-shaped moving plate via a spraying mechanism. The drive rod is connected to a cylindrical casting via a rotation mechanism. The outer wall of the drive rod is connected to uniformly distributed stirring blades via a transmission mechanism. The magnetic suspension liquid sprayed from the spray head is sprayed through a delivery pipe and a bend pipe, and the sprayed magnetic suspension liquid is sprayed onto the surface of the casting. The drive motor drives the moving plate to move at a slow and even speed via the drive rod. The moving plate drives the spray head to move via the bend pipe. At the same time, the drive rod drives the drive disk to rotate. Since the bottom of the casting abuts against the top of the drive disk, the casting also rotates with the rotation of the drive disk. The rotating casting allows the moving magnetic suspension liquid to be sprayed evenly onto the surface of the casting.

[0004] However, in the above technical solution, the stirring blade is set inside the liquid storage tank, which makes the stirring blade easy to corrode and difficult to maintain. In addition, the casting only rotates by frictional contact between the bottom and the drive plate. For castings with smooth surfaces or heavy weight, insufficient friction may cause the rotation to slip or be uneven. The casting may deviate or fall off the drive plate during rotation, requiring frequent manual adjustment, which is time-consuming and labor-intensive, thus affecting the efficiency and quality of casting crack detection. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a precision casting crack detection device that eliminates the need for stirring blades in the storage tank, avoiding the corrosion and maintenance difficulties of stirring blades. At the same time, it uses multiple spray points to spray the casting in a movable manner without rotating the casting, thereby improving the efficiency and quality of casting crack detection.

[0007] To achieve the above objectives, this utility model proposes a precision casting crack detection device, comprising a stirring assembly, a liquid storage ball, a pressurizing pump, a detection box, a driving assembly, a multi-directional spraying component, and two supporting components. The liquid storage ball is rotatably mounted on the stirring assembly and has a rotating connecting pipe. The pressurizing pump has a first connecting pipe and a second connecting pipe, one end of the first connecting pipe being rotatably connected to the rotating connecting pipe, and the second connecting pipe being connected to the multi-directional spraying component. The detection box is located on one side of the stirring assembly and has a supporting plate. The driving assembly is mounted on the supporting plate. The multi-directional spraying component is mounted on the driving assembly. The two supporting components are respectively mounted on the inner walls of both sides of the detection box and located on one side of the supporting plate.

[0008] This utility model discloses a precision casting crack detection device that eliminates the need for stirring blades in the liquid storage tank, avoiding the corrosion and maintenance difficulties associated with stirring blades. Furthermore, it employs multiple spray points to spray the casting in a mobile manner, without requiring the casting to be rotated, thereby improving the efficiency and quality of casting crack detection.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The precision casting crack detection device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the precision casting crack detection device of this utility model embodiment may include a stirring assembly 1, a liquid storage ball 2, a pressurizing pump 3, a detection box 4, a drive assembly 5, a multi-directional spraying component 6, and two support components 7.

[0023] The liquid storage ball 2 is rotatably mounted on the stirring assembly 1, and a rotating connecting pipe 20 is provided on the liquid storage ball 2.

[0024] It should be noted that the testing box 4 described in this example is equipped with a testing device (not shown in the figure). This testing device is existing technology and can detect cracks in castings. The specific structure is not described in detail here.

[0025] It should be noted that the liquid storage ball 2 described in this embodiment is a sphere, and the rotating connecting pipe 20 on the liquid storage ball 2 is set at the fixed rotation point of the liquid storage ball 2, so that the rotation of the stirring assembly 1 drives the stirring ball to rotate, and there is no need to set stirring blades inside the liquid storage ball 2, which facilitates maintenance.

[0026] The pressurizing pump 3 is equipped with a first connecting pipe 30 and a second connecting pipe 31. One end of the first connecting pipe 30 is rotatably connected to the rotating connecting pipe 20, and the second connecting pipe 31 is connected to the multi-directional spraying component 6.

[0027] It should be noted that the first connecting pipe 30 and the second connecting pipe 31 described in this embodiment are flexible tubes, so as to prevent the connection failure caused by pulling the first connecting pipe 30 and the second connecting pipe 31.

[0028] The detection box 4 is located on one side of the stirring assembly 1. A support plate 40 is provided on the detection box 4. The drive assembly 5 is located on the support plate 40. The multi-directional spraying component 6 is located on the drive assembly 5.

[0029] In this embodiment, the multi-directional spraying component 6 is used to spray magnetic suspension liquid in multiple directions onto the casting, thereby ensuring the spraying quality of the casting.

[0030] Two support members 7 are respectively installed on the inner walls of the two sides of the test box 4 and located on one side of the support plate 40.

[0031] In this embodiment, the support member 7 is used to stably support the casting, thereby ensuring the stable support effect of the casting.

[0032] Specifically, in actual operation, the relevant operators place both ends of the casting on the corresponding support 7, start the device, and the controller controls the stirring component 1 to rotate, which in turn drives the liquid storage ball 2 to rotate, thereby making the magnetic suspension liquid in the liquid storage ball 2 evenly stirred. The controller controls the pressurizing pump 3 to move, and the pressurizing pump 3 delivers the liquid in the liquid storage ball 2 from the first connecting pipe 30 through the pressurizing pump 3 and the second connecting pipe 31 to the multi-directional spraying component 6. The multi-directional spraying component 6 sprays the casting in multiple directions. The controller controls the driving component 5 to move, and the driving component 5 drives the multi-directional spraying component 6 to move and spray the casting, thereby completing the spraying of the casting.

[0033] In one embodiment of this utility model, such as Figures 1-3 As shown, the stirring assembly 1 may include a stirring bracket 10 and a stirring motor 11.

[0034] The liquid storage ball 2 is rotatably mounted on the stirring support 10, and the stirring motor 11 is mounted on the stirring support 10. The output shaft of the stirring motor 11 is connected to the liquid storage ball 2.

[0035] It is understandable that by setting up the stirring motor 11 and the liquid storage ball 2, the stirring motor 11 can drive the liquid storage ball 2 to rotate, thereby driving the magnetic suspension liquid inside the liquid storage ball 2 to be stirred evenly. In addition, the stirring motor 11 can rotate in both directions, thereby further improving the uniform stirring effect of the magnetic suspension liquid.

[0036] In one embodiment of this utility model, such as Figures 1-3 As shown, the drive assembly 5 may include a drive motor 50, a reciprocating lead screw 51, and a drive block 52.

[0037] The drive motor 50 is mounted on the detection box 4, the reciprocating screw 51 is rotatably mounted inside the detection box 4, the output shaft of the drive motor 50 is connected to the reciprocating screw 51, the drive block 52 is sleeved on the reciprocating screw 51, and the drive block 52 is slidably connected to the support plate 40.

[0038] It is understandable that by setting the reciprocating screw 51, the drive block 52 moves back and forth on the reciprocating screw 51, thereby realizing the reciprocating movement of the multi-directional spraying component 6 on the drive component and reciprocating spraying of the casting.

[0039] In one embodiment of this utility model, such as Figures 1-3 As shown, the multi-directional spraying component 6 may include a main spray pipe 60 and a plurality of serpentine pipes 61.

[0040] The spray main pipe 60 is mounted on the drive assembly 5, one end of the second connecting pipe 31 is connected to the spray main pipe 60, and multiple serpentine pipes 61 are respectively mounted on the spray main pipe 60 and connected to the spray main pipe 60.

[0041] It should be noted that the serpentine tube 61 described in this embodiment is prior art. It is a tubular component with a bend resembling a gooseneck and typically has flexible and bendable characteristics or a rigid bending structure at a specific angle. Its shape is often "S"-shaped or a continuous arc, and the material is commonly metal (such as carbon steel or stainless steel) or corrosion-resistant plastic. It is often used when it is necessary to change the direction of fluid transport.

[0042] In one embodiment of this utility model, such as Figures 1-3 As shown, the support member 7 may include a fixing plate 70 and a placement plate 71.

[0043] The fixing plate 70 is installed on the inner wall of the detection box 4, and the placement plate 71 is installed on the fixing plate 70.

[0044] Understandably, by setting up the placement plate 71, the casting can be placed on the placement plate 71 without clamping or rotating the casting, thus ensuring the fixing effect of the casting.

[0045] Specifically, in actual operation, the relevant operators place both ends of the casting on the corresponding placement plates 71, start the device, and the controller controls the stirring motor 11 to rotate, which in turn drives the liquid storage ball 2 to rotate, thereby making the magnetic suspension liquid in the liquid storage ball 2 evenly stirred. The controller controls the pressurizing pump 3 to move, and the pressurizing pump 3 delivers the liquid in the liquid storage ball 2 from the first connecting pipe 30 through the pressurizing pump 3 and the second connecting pipe 31 to the spraying main pipe 60, and continues to deliver it to each serpentine pipe 61. The serpentine pipe 61 sprays the casting in multiple directions. The controller controls the drive motor 50 to rotate, and the drive motor 50 drives the reciprocating screw 51 to rotate. The reciprocating screw 51 controls the drive block 52 to slide on the support plate 40, thereby moving the multi-directional spraying component 6, so that the serpentine pipe 61 in the multi-directional spraying component 6 moves and sprays the casting, thus completing the spraying of the casting.

[0046] In summary, the precision casting crack detection device of this utility model eliminates the need for stirring blades in the storage tank, avoiding corrosion and maintenance difficulties. Furthermore, it uses multiple spray points to spray the casting in a mobile manner, eliminating the need to rotate the casting, thereby improving the efficiency and quality of casting crack detection.
