[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1 As shown, Figure 1 The diagram shown is a schematic representation of a casting in the background art.

[0026] The casting 1 includes a thin-walled inspection section 101 disposed on both sides, and an extension section 102 and an extension section 103 are respectively disposed on both sides of the casting 1 near the inspection section 101.

[0027] like Figure 2 , Figure 3 As shown, Figure 2 The diagram shown is a three-dimensional schematic of the fit between the testing fixture and the casting in the embodiment. Figure 3 The diagram shown is a three-dimensional schematic of the detection fixture in the embodiment;

[0028] This device includes:

[0029] The base 10 and the positioning component are disposed on the base 10.

[0030] The base 10 serves as the foundation platform for the entire testing fixture, providing support and stability. The positioning components enable the fixing and positioning of the casting 1.

[0031] The positioning component includes support columns 11 symmetrically arranged on the base 10 and positioning columns 12 arranged in groups, with multiple groups of positioning columns 12 arranged in a region on one side of the support columns 11 that are close to each other.

[0032] Support columns 11 are positioned at the corresponding extension 102 of casting 1. Support columns 11 are used to support the extension 102 of casting 1, achieving initial fixation of casting 1. In this embodiment, the number of positioning columns 12 is three sets evenly spaced. The middle part of casting 1 is positioned between each set of positioning columns 12. Positioning columns 12 can further help fix casting 1 and ensure that the installation position of casting 1 is correct during the inspection process.

[0033] The positioning component also includes symmetrically arranged grouped anti-mistake parts 13, which are located on the side of the support columns 11 that are far apart from each other.

[0034] The error prevention part 13 is provided at the position of the extension part 2 103 corresponding to the casting 1, so that the extension part 2 103 can be inserted. The error prevention part 13 not only helps to accurately position the casting 1, but also prevents incorrect installation, ensuring that the casting 1 can be placed on the inspection fixture in the same way every time, thereby improving the accuracy and consistency of the inspection.

[0035] like Figure 2 , Figure 3 , Figure 4 As shown, Figure 2 The diagram shown is a three-dimensional schematic of the fit between the testing fixture and the casting in the embodiment. Figure 3 The diagram shown is a three-dimensional schematic of the detection fixture in the embodiment; Figure 4 The diagram shown is a plan view of the fit between the testing fixture and the casting in the embodiment.

[0036] This device also includes:

[0037] The detection component 20 includes symmetrically arranged and grouped bases 21. The bases 21 have an internal mounting cavity 22. Detection blocks 23 are movably embedded in the mounting cavity 22 along the horizontal direction. The ends of the detection blocks 23 that are close to each other extend out of the bases 21. Sensors are arranged in the mounting cavity 22. A display 24 connected to the sensor signal is also arranged on the outside of the bases 21.

[0038] After the part to be inspected 101 of the casting 1 extends into the base 21, it abuts against the detection block 23. The detection block 23 retracts into the mounting cavity 22, and the sensor detects its displacement and transmits it to the display 24.

[0039] After the casting 1 is correctly installed using the above positioning components, the part to be inspected 101 of the casting 1 extends between the two bases 21. At this time, the part to be inspected 101 of the casting 1 will contact the detection block 23 and cause the detection block 23 to retract into the mounting cavity 22. The detection block 23 can sensitively respond to any slight displacement or deformation of the part to be inspected 101.

[0040] The sensor is installed in the mounting cavity 22 to detect the displacement of the detection block 23 caused by the pressure of the part to be inspected 101. The sensor converts the captured displacement information into an electrical signal. The display 24 receives the data from the sensor and displays it, so that the user can directly read the deformation of the part to be inspected 101 of the casting 1.

[0041] The symmetrical structure of the detection component 20 allows for simultaneous detection of both sides of the part to be inspected 101. Data acquisition of the deformation on both sides of the part to be inspected 101 can be completed in a single operation, simplifying the operation steps, reducing the workload of operators, and improving detection efficiency.

[0042] like Figure 5 , Figure 6 As shown, Figure 5 The diagram shown is a schematic representation of the internal structure of the detection unit in the embodiment; Figure 6 What is shown is Figure 5 Enlarged structural diagram at point A;

[0043] The detection block 23 includes a contact end 231, which is a portion extending out of the base 21. The portion of the detection block 23 located in the mounting cavity 22 is provided with a limit end 232. A spring 233 connecting the limit end 232 and the base 21 is also provided.

[0044] The contact end 231 directly contacts the part to be inspected 101 of the casting 1. Specifically, the contact end 231 is spherical and has a smooth curved surface. When it contacts the part to be inspected 101, it can naturally guide the part to be inspected 101 into the inspection area. The limiting end 232 can limit the movement range of the inspection block 23. When there is no external force (i.e., the part to be inspected 101 does not apply pressure to the contact end 231), the spring 233 will play a reset role and push the inspection block 23 back to the initial position to prepare for the next inspection.

[0045] The sensor includes a fixed grid 2111 disposed on the inner wall of the mounting cavity 22 and a movable grid 2321 disposed on the side wall of the limiting end 232. The fixed grid 2111 and the movable grid 2321 are close to each other and form capacitive coupling.

[0046] Specifically, the sensor is a capacitive displacement sensor. The fixed grid 2111 is set on the inner wall of the mounting cavity 22 as a fixed part, providing a stable reference position. The moving grid 2321 is located on the side wall of the limiting end 232 and changes position as the detection block 23 moves. The moving grid 2321 and the fixed grid 2111 are close to each other and maintain a certain gap. Together, they form part of the capacitor structure. When the position of the moving grid 2321 relative to the fixed grid 2111 changes, the capacitance value between the two will change. This capacitance change is captured and converted into an electrical signal and transmitted to the display 24, which finally displays the specific displacement.

[0047] Specifically, the sensor also includes signal conversion and processing components found in existing technologies, used to capture capacitance changes and process them into readable digital information.

[0048] Working principle: First, the casting 1 is correctly installed on the inspection fixture. At this time, the part to be inspected 101 can accurately enter the inspection area. After the part to be inspected 101 of the casting 1 extends between the two bases 21, it contacts the spherical contact end 231 of the inspection block 23. The part to be inspected 101 will apply pressure to the spherical contact end 231. At the same time, the inspection block 23 begins to retract into the mounting cavity 22, which drives the moving grid 2321 to move. As the position of the moving grid 2321 relative to the fixed grid 2111 changes, the capacitance value between the two changes and is converted into an electrical signal and transmitted to the display 24. The display 24 receives and displays the specific displacement or deformation information for the operator to view and analyze.

[0049] After the test is completed and the external force disappears, the spring 233 automatically pushes the detection block 23 back to the initial position, ready for the next test.

[0050] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
