Description

Technical Field

[0001] This utility model belongs to the field of casting product testing technology, specifically relating to a fluorescent detection mesh isolation device for sequential detection of small and medium-sized castings. Background Technology

[0002] In the production chain of modern precision casting industry, the quality control of small castings is crucial because they are widely used in various complex mechanical structures and equipment components. Fluorescent detection technology, as a highly sensitive and non-destructive testing method, plays a central role in screening surface defects (such as cracks, inclusions, and porosity) in small castings. However, traditional fluorescent detection processes have revealed serious limitations when dealing with large-scale small casting inspection tasks.

[0003] Due to the lack of an effective individual differentiation mechanism, and the inability to mark the surfaces of many small castings, precise one-to-one correspondence during inspection is difficult. This leads to a blurred correlation between inspection data and the specific casting. Once a casting reveals quality issues in subsequent use, tracing back inspection information to pinpoint the root cause becomes extremely difficult. This not only severely hinders the timely location and correction of quality problems but also significantly increases production and time costs, posing a serious challenge to the efficiency and stability of the entire production process. Therefore, developing an innovative method and device that ensures orderly and traceable inspection of small castings during fluorescent testing is urgently needed. Utility Model Content

[0004] This invention aims to solve the technical problem of inaccurate correspondence between small castings and test data and lack of traceability under traditional testing methods.

[0005] This utility model provides the following technical solution: a fluorescent detection mesh isolation device for sequential detection of small and medium-sized castings, including a frame, the frame being divided into multiple isolation units by a mesh structure, each isolation unit being able to clamp a workpiece and corresponding to a unique coordinate identification information.

[0006] Furthermore, the frame is woven with horizontal and vertical grid lines to form a layered mesh structure. The upper and lower mesh structures are aligned, and the aligned grids in the upper and lower mesh structures form an isolation unit. The horizontal and vertical coordinates of the grid serve as the coordinate identification information of the isolation unit.

[0007] Furthermore, the frame includes unit frames with the same number of layers as the mesh structure, and the unit frames are connected to each other by columns, with the mesh structure connected one-to-one in the unit frames.

[0008] Furthermore, there are two layers of mesh structure within the frame; the unit frame has holes, and the two ends of the mesh cable are equipped with pins. The pins at both ends of the mesh cable are inserted into the corresponding holes to taut and stretch the mesh cable within the unit frame. The insertion and removal directions of the pins on the mesh cable in the two layers of mesh structure are opposite.

[0009] Furthermore, the network cable includes a heat-resistant soft plastic outer sheath and an alloy wire inner core.

[0010] Furthermore, handles are installed on the frame.

[0011] Furthermore, the frame is a rectangular frame, with the horizontal and vertical grid lines parallel to the horizontal and vertical sides of the frame, respectively.

[0012] Furthermore, the pin includes a pin rod and a pin cap.

[0013] Furthermore, the unit frame is provided with a retaining edge.

[0014] Compared with the prior art, the advantages of this utility model are: This utility model provides a mesh-like isolation device for sequential detection of small and medium-sized castings using fluorescent detection. The device's internal space is divided into multiple independent isolation units of uniform size and specifications through a finely woven mesh structure. Each isolation unit is designed to fully consider the size characteristics and detection requirements of small castings. Its size is just right, stably accommodating a single small casting to prevent displacement and shaking during detection, while ensuring that the fluorescent detection light can cover the casting surface comprehensively and without blind spots, guaranteeing the integrity and accuracy of the detection data. By recording the grid coordinates of the small castings, orderly and traceable detection of small castings is achieved, reducing the possibility of loss of control during the production process. This effectively solves the long-standing problem of correspondence and traceability in the field of fluorescent detection of small castings, injecting new vitality and technical support into the quality improvement and refined management of the casting industry, and has broad application prospects and significant economic benefits.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] like Figures 1-5 As shown: A fluorescent detection device for sequential detection of small and medium-sized castings with a mesh-like isolation structure includes a frame 1. The frame 1 is divided into multiple isolation units by a mesh structure. Each isolation unit can clamp a workpiece and corresponds to a unique coordinate identification information.

[0019] Within frame 1, horizontal and vertical mesh lines 2 are woven into a layered mesh structure. The upper and lower mesh structures are aligned, and the aligned grids in the upper and lower mesh structures form an isolation unit. The horizontal and vertical coordinates of the grid serve as the coordinate identifiers of the isolation unit. The layered mesh structure can clamp irregularly shaped small castings at multiple points, which can not only stably accommodate small castings and prevent displacement and shaking during the inspection process, but also ensure that the fluorescent detection light can cover the casting surface in all directions without blind spots, thus guaranteeing the integrity and accuracy of the inspection data.

[0020] Frame 1 includes unit frames 1.1 with the same number of layers as the mesh structure. Frame 1 is a hollow structure for weight reduction. Each layer of unit frames 1.1 is connected by columns 1.2. The mesh structure is connected one-to-one in the unit frames 1.1.

[0021] The frame 1 has two layers of mesh structure; the unit frame 1.1 has a socket 1.2, and the two ends of the mesh wire 2 are provided with pins 3. The pins 3 at both ends of the mesh wire 2 are inserted into the corresponding sockets 1.2 to stretch the mesh wire 2 taut in the unit frame 1.1. The insertion and removal directions of the pins 3 on the mesh wire 2 in the two layers of mesh structure are opposite; the pins 3 in the upper unit frame 1.1 are pulled upwards, and the pins 3 in the lower unit frame 1.1 are pulled downwards; this allows for easy adjustment of the number of mesh wires 2 according to the size of the casting.

[0022] Frame 1 is a metal frame, made of materials such as stainless steel, aluminum alloy, and iron; the mesh cable 2 includes a heat-resistant soft plastic outer sheath and an alloy wire core (3J22 elastic alloy wire, operating temperature -200~+450℃). The heat-resistant plastic outer sheath protects the surface of the casting, while the elastic alloy wire core ensures the stability of the casting after placement and provides a certain degree of toughness, reducing the impact of casting variations on detection. This structural design ensures the overall structural stability and heat resistance of the device under high-temperature fluorescence detection environments (withstanding temperatures up to 120℃ without deformation or damage), while also providing appropriate flexibility for easy adaptation and operation in different detection scenarios and equipment.

[0023] A handle 4 is installed on the frame 1 for easy handling of the entire device.

[0024] The frame 1 is a rectangular frame, with the horizontal and vertical grid lines 2 parallel to the horizontal and vertical sides of the frame 1, respectively, to facilitate marking the coordinates of each grid; the frame 1 is equipped with laser etching to mark the horizontal and vertical coordinates of the grid.

[0025] The pin 3 includes a pin rod 3.1 and a pin cap 3.2; the pin rod 3.1 of the pin 3 is inserted into the insertion hole 1.2 of the unit frame 1.1, and the pin cap 3.2 acts as a limit to restrict the insertion depth of the pin rod 3.1, while pinching the pin cap 3.2 makes it easy to insert and remove the pin 3; a retaining edge 1.3 is provided on the unit frame 1.1, which surrounds the pin cap 3.2 and protects the pin 3.

[0026] Before small castings enter the fluorescence detection stage, the mesh isolation device is first thoroughly cleaned and inspected to ensure that there are no impurities remaining in its internal isolation units and that its structure is intact.

[0027] At the forefront of the fluorescence inspection process on the small casting production line, a dedicated preparation area for a mesh isolation device is set up. This area pre-screens and sorts the small castings before they enter the inspection process, removing surface impurities and obvious defects. Then, according to the predetermined production batch and inspection sequence, qualified castings are placed one by one into the isolation units of the mesh isolation device. During placement, operators fine-tune the placement and orientation of the castings, ensuring that key inspection surfaces (such as areas prone to defects) face a uniform, preset direction. This provides strong assurance for the consistency and accuracy of subsequent fluorescence inspection, guaranteeing that the castings fully meet the inspection requirements.

[0028] Based on the isolation unit identification information, time information, and fluorescence detection data, a detection information file is constructed for each small casting to achieve one-to-one correspondence and traceability of casting detection.

[0029] Throughout the production process, whether it's the quality control department conducting regular spot checks or receiving customer quality feedback in the after-sales stage, the corresponding inspection information files can be found based on the casting information (such as production batch number, casting number, etc.), and presented to relevant personnel in an intuitive and detailed report format. This information will provide crucial basis for the analysis and localization of quality problems, helping enterprises to take timely and effective corrective and preventive measures, and continuously improve the production quality and management level of small castings.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
