Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a steel section inspection tool. Background Art

[0002] Special-shaped steel is the abbreviation of complex and special-shaped cross-section steel. It is a type of steel and is different from simple cross-section steel. Due to the special and single nature of its use, special-shaped steel often has higher requirements for accuracy than simple cross-section steel, which places higher requirements on the equipment's capabilities. Due to its complex cross-sectional shape, especially special-shaped steel used in many specific occasions, traditional cross-sectional gauges, such as vernier calipers, are not only complicated to operate when inspecting special-shaped steel structures, but also cannot fully meet the inspection requirements.

[0003] After development, special-shaped steel slices are currently mostly inspected using projectors or three-dimensional coordinates. Both inspection methods require the production workshop to stop and wait for inspection before continuing production or adjusting the mold and trial-producing again. Stopping and waiting makes the production efficiency of steel low, which in turn leads to increased steel costs.

[0004] In response to the above problem, a Chinese patent with publication number CN213778837U was found through searching, which proposed a special gauge for special-shaped steel, including an inspection plate, the inspection plate is provided with an inspection hole adapted to the cross-sectional shape of the special-shaped steel, the inspection hole includes a first accommodating portion, the first accommodating portion is bent and extended to form a second accommodating portion, the second accommodating portion is bent and extended to form a third accommodating portion, the third accommodating portion is bent and extended to form a fourth accommodating portion, and the fourth accommodating portion is bent and extended to form a fifth accommodating portion. According to the above scheme, the special gauge for special-shaped steel can meet the inspection of the overall size of the special-shaped steel while meeting the inspection of the local size, and the phenomenon that the local size is measured separately and qualified but the overall size does not meet the requirements will not occur.

[0005] In the above technical scheme, the test result is obtained by passing the special-shaped steel through the inspection hole that matches its cross-section and observing the degree of fit between the special-shaped steel and the inspection hole. The operation is simple and the detection effect is high. However, the above technical scheme has certain problems, that is, the steel is prone to distortion when it is just demolded and has not been straightened. There are bent parts in the steel as a whole, and it is difficult to pass the bent part of the steel through the inspection hole, resulting in low inspection efficiency.

[0006] Therefore, the present application provides a steel section gauge to meet the needs. Utility Model Content

[0013] Optionally, a diameter of the bottom edge is greater than a diameter of the connecting seat, the diameter of the bottom edge is greater than an inner diameter of the mounting hole, and a diameter of the rotating shaft is the same as the inner diameter of the mounting hole.

[0014] Optionally, the outer edge of the detection core plate is arc-shaped, and the arc-shaped structure is called an arc-shaped outer edge.

[0033] The following is a detailed description of a steel section gauge provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0034] It should be noted that the references to "one embodiment", "an embodiment", "an exemplary embodiment", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0035] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0036] It is to be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers.

[0037] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0038] like Figures 1 to 7 As shown, an embodiment of the utility model provides a steel section inspection tool, including a handle 1, an inner inspection plate 2 and an outer inspection plate 3, wherein the inner inspection plate 2 and the outer inspection plate 3 are respectively arranged at both ends of the handle 1 and are rotatably connected to the handle 1, the structure of the inner inspection plate 2 is adapted to the internal structure of the curved steel 5, and an inspection groove is provided on the surface of the outer inspection plate 3, and the inspection groove structure is adapted to the external structure of the curved steel 5, the handle 1 includes a rod body 11, and the rod body 11 is a special-shaped rod structure with thick ends and thin middle, and the side edges of the rod body 11 are all chamfered in an arc shape, the handle 1 is made thin in the middle for the user to grip, and the handle 1 is made thick at both ends to increase the bottom area, so that the inner inspection plate 2 and the outer inspection plate 3 can be installed more stably.

[0039] like Figure 3 to Figure 4The handle 1 is integrally connected to a base 12 at both ends, and a connecting pile 13 is integrally connected to the surface of the base 12. The outer surface of the connecting pile 13 is engraved with an external thread, and a mounting hole 14 is opened on the bottom surface of the connecting pile 13. The mounting hole 14 is a blind hole structure. The inner mold inspection plate 2 is an overall "7"-shaped structure. The upper half of the inner mold inspection plate 2 is called the detection core plate 21. The structure of the detection core plate 21 is compatible with the inner surface structure of the curved steel 5. The lower half of the inner mold inspection plate 2 is integrally connected to a connecting seat 22, and the bottom of the connecting seat 22 is integrally connected to a bottom edge 23, and a rotating shaft 24 is integrally connected to the bottom edge 23. The diameter of the bottom edge 23 is larger than the diameter of the connecting seat 22, the diameter of the bottom edge is larger than the inner diameter of the mounting hole 14, and the diameter of the rotating shaft 24 is the same as the inner diameter of the mounting hole 14. When connected to the handle 1, the rotating shaft 24 is embedded in the mounting hole 14 and rotatably connected to the handle 1. The outer edge of the detection core plate 21 is arc-shaped, and the arc-shaped structure is called an arc-shaped outer edge 25. When the inner profile inspection plate 2 inspects the curved steel 5, the detection core plate 21 is embedded in the cross-section of the curved steel 5. The arc-shaped top of the arc-shaped outer edge 25 of the inner profile inspection plate 2 contacts the inside of the cross-section of the curved steel 5. The arc-shaped outer edge 25 can just be in complete contact with the inside of the cross-section of the curved steel 5, but there will not be too large a contact surface. This makes it possible for the inner profile inspection plate 2 to move along the bend of the curved steel 5 without difficulty in moving due to the large contact surface. Moreover, when rotating along the curved steel 5, the arc-shaped outer edge 25 can always be in complete contact with the cross-section of the curved steel 5 when the inner profile inspection plate 2 is deflected, thereby improving the detection accuracy.

[0040] like Figure 5 The exterior inspection plate 3 comprises an inspection frame plate 31, and an inspection groove 35 is provided on the surface of the inspection frame plate 31. The inspection groove 35 is an open structure. The structure of the inspection groove 35 is adapted to the external structure of the cross-section of the curved steel 5. The inspection groove 35 is a through groove structure, and the cross-section of the inspection groove 35 is an unclosed open structure, which is convenient for the curved steel 5 to pass through the inspection groove 35 for cross-section inspection. At the same time, the open inspection groove 35 allows the inspection plate to still be slightly rotated when the curved steel 5 passes through the inspection groove 35, so as to change the force angle applied to the exterior inspection plate 3, so that the user can easily push the exterior inspection plate 3 to move along the curved steel 5. The inner surface edge of the inspection groove 35 is arc-shaped, and the arc-shaped structure is called the arc inner edge 36.

[0041] like Figures 5 and 6The arc inner edge 36 and the arc outer edge 25 have the same function, both of which are to reduce the contact area with the curved steel 5 so that it can be easier to move along the bending part of the curved steel 5. The outer edge of the detection frame plate 31 is integrally connected with a connecting seat 2 32, and a bottom edge 2 33 is integrally connected to the connecting seat 2 32. A rotating shaft 2 34 is integrally connected to the connecting seat 2 32. The connecting seat 2 32, the bottom edge 2 33 and the rotating shaft 2 34 are respectively the same in structure as the connecting seat 1 22, the bottom edge 1 23 and the rotating shaft 1 24. The connecting seat 1 22 is sleeved with a clamping cap 4, and the clamping cap 4 is clamped with the connecting seat 1 22 through the bottom edge 1 23. The inner surface of the clamping cap 4 is engraved with an internal thread that matches the external thread on the connecting pile 13. When the inner inspection plate 2 is connected to the handle 1, the clamping cap 4 is threadedly connected to the connecting pile 13 to lock the inner inspection plate 2. The connecting seat 32 of the outer inspection plate 3 is also provided with a clamping cap 4. The connection method between the outer inspection plate 3 and the handle 1 is the same as that of the inner inspection plate 2. The clamping cap 4 is fixedly connected to the connecting pile 13. The inner inspection plate 2 and the outer inspection plate 3 and the handle 1 can be rotated with each other to facilitate detection. The inner inspection plate 2 and the outer inspection plate 3 and the handle 1 are connected by the clamping cap 4, which is convenient for disassembly, and convenient for replacing the inner inspection plate 2 or the outer inspection plate 3 with different structures.

[0042] The working principle of the steel section gauge provided by the utility model is as follows:

[0043] When inspecting the cross section of the curved steel 5, the internal structure and external structure of the curved steel 5 can be inspected respectively by the inner inspection plate 2 and the outer inspection plate 3. When the inner inspection plate 2 inspects the internal structure of the curved steel 5, the inspection core plate 21 is embedded in the curved steel 5 and moved from one end of the curved steel 5 to the other end along the edge of the curved steel 5, so that the curved steel 5 is inspected as a whole to avoid local unevenness and improve the inspection accuracy. When the outer inspection plate 3 inspects the external structure of the curved steel 5, the inspection groove is clamped on the outside of the curved steel 5, and the inspection is also completed by moving from one end of the curved steel 5 to the other end.

[0044] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
