Abstract
Description
Technical Field
[0001] The present application relates to the technical field of metal casting detection, and in particular to a measuring tool for frame beam castings. Background Art
[0002] Large and complex frame beam castings have very strict dimensional requirements. After casting, the wall thickness and contour structure of the frame beam castings need to be measured using conventional tools such as calipers and calipers and 3D scanners or coordinate measuring machines, especially the accuracy of the overlap area. However, this traditional testing method is time-consuming and costly.
[0003] Because the production process for this large, complex frame beam casting is lengthy and involves numerous repair welding and polishing steps, the overlapped areas are prone to dimensional changes and structural deformation. This often requires repeated measurement and confirmation using a 3D scanner or CMM, which increases production cycles. Furthermore, small areas of missing or excess material are difficult to confirm using a 3D scanner or CMM, creating the risk of dimensional disqualification at the overlapped areas. Utility Model Content
[0004] In view of the problems existing in the background technology, the present application provides a measuring tool for frame beam type castings. The special measuring tool is designed according to the location characteristics of the overlap area of large and complex frame beam type castings, which can achieve accurate measurement of the structural position, greatly shorten the measurement time, improve efficiency and reduce costs.

[0006] By using the measuring fixture for frame beam type castings in the present technical solution, utilizing the processing surface formed on the main body of the frame beam type casting close to the overlapping area, designing a positioning structure adapted to the processing surface and a detection structure adapted to the overlapping area, when measuring the overlapping area, it is only necessary to lay the frame beam type casting flat with the overlapping area facing upward, and then position the positioning structure and the processing surface, place the detection structure in the overlapping area, and observe whether the detection structure and the overlapping area contour coincide, so that the measurement can be completed quickly. According to the measurement results, repair operations such as grinding or repair welding can be performed in time, avoiding the use of more complex and more costly measurement methods, saving manpower and material resources, greatly shortening the measurement time, improving measurement efficiency, reducing costs, and having high measurement accuracy.

[0020] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0021] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0022] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.
[0023] The embodiment of the present application discloses a measuring tool for frame beam castings, such as Figure 1 As shown, the frame beam casting includes a body 1 , an overlap region 2 is formed on one side of the body 1 , and a processing surface 3 is formed on the body 1 near the overlap region 2 .
[0024] like Figure 2 and Figure 3 As shown, the measuring tooling includes a positioning structure 4 and a detection structure 5. The positioning structure 4 is used to position and fit with the processing surface 3; the detection structure 5 is connected to the positioning structure 4 and adapts to the contour of the overlapping area 2. After the positioning structure 4 is positioned and fit with the processing surface 3, the detection structure 5 is placed in the overlapping area 2.
[0025] In the present invention, by utilizing the processing surface 3 formed on the main body 1 of the frame beam type casting close to the overlapping area 2, a positioning structure 4 adapted to the processing surface 3 and a detection structure 5 adapted to the overlapping area 2 are designed. When measuring the overlapping area 2, it is only necessary to lay the frame beam type casting flat with the overlapping area 2 facing upward, and then position the positioning structure 4 and the processing surface 3, and place the detection structure 5 in the overlapping area 2 to observe whether the contours of the detection structure 5 and the overlapping area 2 coincide. If they coincide, it means that the contour structure of the position is qualified. If they cannot coincide, it means that there is a deviation in the contour structure of the position, and repair operations such as grinding or repair welding are required, thereby achieving accurate measurement of the structural position, greatly shortening the measurement time, improving measurement efficiency, and reducing costs.
[0026] In some embodiments of the present invention, Figure 2 As shown, the detection structure 5 includes a detection plate, one side of which is a detection surface 51 adapted to the side wall of the overlapping area 2.
[0027] The detection structure 5 is formed by the detection plate and the detection surface 51 thereon, and the molding quality of the overlap area 2 is judged by the degree of fit between the detection surface 51 and the side wall of the overlap area 2. This has not only a simple structure but also convenient and accurate measurement.
[0028] Furthermore, the thickness of the detection plate is greater than or equal to the depth of the overlapping area 2. Preferably, the thickness of the detection plate is equal to the depth of the overlapping area 2, that is, the width of the detection surface 51 can just cover the side wall of the overlapping area 2, so that while the detection plate performs a one-time full-area detection of the overlapping area 2, the weight of the detection plate and the obstruction of the outline of the overlapping area 2 by the detection surface 51 are reduced, which facilitates the operation of the measuring tool and the observation of the measurement situation.
[0029] In some embodiments of the present invention, Figure 2 As shown, the positioning structure 4 includes a positioning plate, one side of which is a positioning surface 41 adapted to the processing surface 3 .
[0030] It should be noted that the positioning plate and the detection plate may be an integrally formed plate-like structure with uniform overall thickness.
[0031] The positioning structure 4 is formed by the positioning plate and the positioning surface 41 thereon, and the positioning surface 41 is fitted with the processing surface 3 near the overlap area 2 to accurately place the detection plate at the corresponding position. This has the advantages of simple structure, convenient operation and high measurement efficiency.
[0032] Furthermore, the number of the positioning plates is more than two, and the more than two positioning plates are connected to each other. Processing surfaces 3 adapted to the positioning surfaces 41 of the positioning plates are respectively formed on the main body 1 near the overlapping area 2 .
[0033] By designing a plurality of positioning surfaces 41 to match the plurality of processing surfaces 3 one by one, the positioning accuracy of the detection plate can be further improved, thereby further improving the detection accuracy of the detection plate.
[0034] It should be noted that, depending on the specific structures of the frame beam casting and the overlapping area 2, the number of the processing surfaces 3 on the main body 1 close to the overlapping area 2 includes but is not limited to one, two or three.
[0035] Specifically, if Figure 1As shown, the overlapping area 2 of the frame beam type casting in the present invention is close to a corner of the main body 1, and has an upper processing surface and a left processing surface perpendicular to each other near the overlapping area 2. Correspondingly, the positioning plate has an upper positioning surface that accurately fits the upper processing surface and an intermediate positioning surface that accurately fits the left processing surface.
[0036] In some embodiments of the present invention, the end corners of the positioning plate are rounded (not shown). By designing the end corners of the positioning plate, especially the positioning plate away from the processing surface 3, as rounded corners, and retaining the right angle on the side of the positioning plate close to the processing surface 3, the safety of the measuring tool can be improved.
[0037] Furthermore, a certain number of through holes (not shown) can be opened in the middle of the positioning plate and / or the detection plate, which can reduce the weight of the measuring tool without affecting the positioning and detection, and further improve the ease of use of the measuring tool.
[0038] In some embodiments of the present invention, the positioning structure 4 and the detection structure 5 are made of alloy; preferably, the positioning structure 4 and the detection structure 5 are made of stainless steel, that is, the positioning plate and the detection plate are stainless steel plate structures, which have a long service life, low price, and are not easy to deform, and can maintain their high measurement accuracy.
[0039] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
