Description

Technical Field

[0001] This utility model belongs to the field of symmetry detection technology and relates to an overflow brick symmetry detection device. Background Technology

[0002] Overflow bricks, as core components of high-temperature melt guiding systems, are increasingly in demand in the modern machining field for parts with complex curved surface structures (such as structures with transitions between planes and inclined arcs). These parts have wide applications in many industries such as aerospace, automotive manufacturing, and precision instruments, and their machining accuracy and quality directly affect the overall performance, service life, and operational stability of the products.

[0003] When machining parts with transitions between flat surfaces and inclined arcs, due to the complexity of the part structure and limitations of the machining process, the common practice is to machine both sides separately, using a second clamping and alignment process. During the initial clamping, one side of the part is machined, including the flat portion and the connected arc transition area. Afterward, the part is disassembled, the clamping position and alignment reference are readjusted, and then the other side is machined.

[0004] However, during the secondary clamping and alignment process, it is difficult to guarantee absolute consistency and precise alignment during machining on both sides, resulting in the inability to effectively measure the symmetry of the arc transition on both sides. Currently used measurement methods, such as coordinate measuring machines, can accurately measure the size and shape parameters of parts, but they lack a direct and efficient measurement method for this problem of symmetry in the arc transition on both sides caused by secondary clamping.

[0007] Furthermore, the first detection device and the second detection device have the same structure; the first detection device is compatible with the brick body.

[0008] Furthermore, the first detection device includes a first detection element and a second detection element installed on one side of the first detection element, and the included angle between the first detection element and the second detection element is a first included angle; the brick body includes a first brick body and a second brick body installed on one side of the first brick body, and the included angle between the first brick body and the second brick body is a second included angle; the first included angle and the second included angle are adapted to each other.

[0009] Furthermore, the first detection element and the second detection element are an integral structure, and the first brick body and the second brick body are an integral structure.

[0010] Furthermore, the second brick body has inverted L-shaped corners at both ends, and the upper surface of the corner is a step surface of the brick body.

[0012] Furthermore, the length of the first detection element is less than the length of the first brick.

[0013] Furthermore, an overflow brick cavity groove is provided on the upper end face of the brick body.

[0014] Furthermore, the upper surface of one side of the first brick is used as the reference surface.

[0015] Furthermore, a handle is fixedly attached to the side of the first testing piece away from the first brick.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This invention discloses a symmetrical inclined plane centering detection device. The measuring device uses the distance between the upper surface of the first detection element in the first detection device and the upper surface of the brick, and the distance between the upper surface of the first detection element in the second detection device and the brick, to accurately quantify and evaluate the symmetry of the brick. Compared to traditional subjective judgment by visual inspection, comparing specific distance values ​​allows for a more objective and efficient determination of the brick structure's symmetry, effectively improving the accuracy and reliability of brick quality inspection and providing a scientific basis for optimizing brick production processes and quality control.

[0018] This invention discloses a symmetrical inclined plane centering detection device. The shapes of the first and second detection devices can be flexibly adjusted according to the shape of the brick, improving adaptability and versatility. Regardless of whether the brick has a complex contour or a standard brick structure, the first and second detection devices can be adjusted to fit closely to the part of the brick to be detected, ensuring accurate positioning of the detection point. Compared with fixed-shape detection, this avoids detection blind spots or data deviations caused by differences in brick shape, effectively expanding the detection range, reducing the cost of repeated equipment investment, and allowing the same detection system to adapt to diverse brick production needs, providing strong support for quality inspection in flexible production scenarios.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings:

[0029] Example 1

[0030] This utility model provides a symmetrical inclined plane centering detection device, such as Figure 1 As shown, it includes a first detection device 1 and a second detection device 2, which are symmetrically installed on both sides of the brick body 3. The first detection device 1 and the second detection device 2 perform symmetry detection on the brick body 3 through a measuring device.

[0031] Specifically, the first detection device 1 and the second detection device 2 have the same structural dimensions. The first detection device 1 includes a first detection element 11 and a second detection element 12, which are integrally formed or fixed by welding, with smooth, burr-free joints. The second detection device 2 is also composed of the first detection element 11 and the second detection element 12. The included angle between the first detection element 11 and the second detection element 12 is a first included angle. The first included angle is as follows: Figure 2 As shown, it is compatible with brick body 3.

[0032] The first included angle between the first inspection piece 11 and the second inspection piece 12 is dynamically adjusted according to the second included angle of the brick 3, that is, the combined angle of the first brick 31 and the second brick 32. Through modular design, users can quickly replace and adapt to various brick types 3 to ensure consistent testing.

[0033] The brick body 3 includes a first brick body 31 and a second brick body 32 installed on one side of the first brick body 31. It should be noted that the second brick body 32 installed on one side of the first brick body 31 is located on the same side as the second detection device 12 installed on one side of the first detection device 11. The first brick body 31 and the second brick body 32 are an integral structure.

[0034] like Figure 3 As shown, the upper surface of the first brick 31 is provided with a groove, such as... Figure 4 As shown, the second brick 32 has inverted L-shaped corners at both ends, the upper surface of the inverted L-shaped corner is the brick step surface, and the upper surface of one side of the first brick 31 is the reference surface. Figure 4 As shown, the two brick steps are located on the same straight line.

[0035] It should be noted that the length of the first detection element 11 is less than the length of the first brick 31, and the length of the second detection element 12 is greater than the distance between the reference plane and the lower end face of the second brick 32. The distance between the reference plane and the lower end face of the second brick 32 is B.

[0036] This utility model discloses an overflow brick symmetry detection device, which further includes a dial indicator. The dial indicator is used to measure whether the distance between the left side of the brick step surface and the lower end face of the first detection element 11 in the first detection device 1, and the distance between the right side of the brick step surface and the lower end face of the first detection element 11 in the second detection device 32 are equal after the second detection element 12 is attached to the second brick body 32. If they are equal, the brick body 3 has a symmetrical structure. It should be noted that the shape of the first detection element 11 is adjusted accordingly based on the brick body 3.

[0037] The distance between the left side of the brick step surface and the lower end face of the first detection element 11 in the first detection device 1 is A1, and the distance between the right side of the brick step surface and the lower end face of the first detection element 11 in the second detection device is B1.

[0038] The first detection device 1 and the second detection device 2 achieve precise quantitative assessment of the symmetry of the brick body 3 through a measuring device. Compared with the subjective judgment of traditional manual visual inspection, this method can more objectively and efficiently determine the structural symmetry of the brick body 3 by comparing specific distance values, effectively improving the accuracy and reliability of the quality inspection of the brick body 3, and providing a scientific basis for the optimization of the brick body 3 production process and quality control. In this embodiment, the measuring device is a dial indicator.

[0039] Finally, to facilitate the use of the first detection device 1 and the second detection device 2, a handle can be provided on the side of the first detection device 1 or the second detection device 2 away from the brick body 3. The handle is fixedly connected to the first detection device 1 or the second detection device 2. The fixed connection includes welding and detachable connection, preferably welding, and the connection is smooth and burr-free.

[0040] Installing handles on the first and second testing devices 1 and 2 significantly improves operational convenience and portability. Operators can more easily move and transport the devices using the handles, especially in multi-station testing or on-site debugging scenarios, greatly reducing manpower burden and operation time. Simultaneously, the handles provide stable grip points, facilitating precise adjustment of the device position during testing to ensure alignment with the brick 3 and avoid testing errors caused by unstable handheld operation.

[0041] The present invention discloses a method for using an overflow brick symmetry detection device, comprising the following steps:

[0042] First, the first detection device 1 and the second detection device 2 are symmetrically installed on both sides of the brick body 3. During the installation process, it is necessary to ensure that the first included angle between the first detection element 11 and the second detection element 12 is the same as the second included angle between the first brick body 31 and the second brick body 32.

[0043] Use a dial indicator to measure whether the distance between the upper end face of the first detection element 11 in the first detection device 1 and the upper end face of the brick 3 is equal to the distance between the upper end face of the first detection element 11 in the second detection device 2 and the brick 3. If they are equal, it is determined that the two sides of the brick 3 are symmetrical.

[0044] A dial indicator can also be used to measure whether the distance between the lower end face of the second detection element 12 in the first detection device 1 and the brick step surface is equal to the distance between the second detection element 12 in the second detection device 2 and the brick step surface. If they are equal, it is determined that the two sides of the rotating body 3 are symmetrical.

[0045] To ensure measurement accuracy, it is recommended to take three consecutive measurements at each testing point and average the results after eliminating gross errors. During operation, it is necessary to maintain a stable measurement environment (such as constant temperature and humidity, and avoid airflow disturbances), use the measuring tool (dial indicator) correctly, and have the same operator complete repeated measurements at a fixed rhythm to reduce errors introduced by differences in operating techniques.

[0046] The method for using a dial indicator is as follows: Place the dial indicator on a flat, level surface. Gently rotate the dial by hand until the pointer points to the zero mark. Ensure the object being measured is stable and avoid shaking that could affect the measurement results. Rotate the dial gently, avoiding excessive force. After measurement, clean and maintain the dial indicator to ensure accuracy for the next use. The dial indicator is read according to the scale. For every 0.01mm movement, the large pointer deflects one division; after more than one full rotation, the small pointer deflects one division. The amount of pointer deflection is the actual deviation or clearance value of the measured part.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
