Description

Technical Field

[0001] This utility model relates to the field of steel wire measurement technology, and more specifically, to a steel wire straightness measuring fixture. Background Technology

[0002] In the field of steel wire production and application, the straightness of steel wire is one of the key indicators for measuring its quality. Accurate measurement of steel wire straightness is of great significance for ensuring product quality, improving production efficiency, and meeting the usage requirements of downstream industries.

[0003] Currently, in terms of measuring the straightness of steel wire, the steel wire material is quite special, and the straightness cannot be detected by instruments such as coordinate measuring machines or two-dimensional measuring machines.

[0004] The specific procedure involves laying the steel wire flat on a level table or vertically at the same height and manually assessing its curvature. However, this method has significant limitations. When faced with two steel wires with similar straightness, visual comparison is insufficient to accurately determine their differences. Due to the subjectivity and limitations of human judgment, it cannot accurately identify subtle differences in straightness and can only address situations with relatively large errors.

[0005] Therefore, developing a measuring fixture capable of accurately measuring and clearly comparing the differences in straightness between steel wires with similar properties is of great practical significance for improving the quality and efficiency of steel wire production.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] Example 1: In order to solve the problem that in traditional steel wire straightness measurement, when faced with two steel wires with similar straightness, it is difficult to judge the difference by visual comparison.

[0027] A wire straightness measuring fixture includes a base 1 and a wire measuring mechanism 2. The wire measuring mechanism 2 is located on top of the base 1. The wire measuring mechanism 2 includes a transparent graduated compass 21, a support rod 22, and a clamping part 23. The base 1 has a cubic structure. The transparent graduated compass 21 is located on top of the titration stage and is used to detect the degree of tilting and bending of the wire. The support rod 22 is located at the bottom of the base 1 and is positioned above the circular graduated plate. The clamping part 23 is located on the outside of the support rod 22 and is used to clamp the wire to be measured.

[0028] In this embodiment, the base 1 is preferably a laboratory titration table structure. First, the worker clamps the steel wire to be tested using the clamping part 23. After clamping, the steel wire is positioned below the clamping part 23 and above the transparent scale compass 21. Using the planar coordinate system formed by the transparent scale compass 21, the position information of the steel wire in this coordinate system is observed and recorded. By observing the position of the steel wire in the coordinate system, the relative degree of bending and tilting of the steel wire can be expressed intuitively and accurately, thus clearly comparing the differences in straightness between different steel wires and presenting the results in numerical form.

[0029] See Figure 2 The wire measuring mechanism 2 also includes a protective plate 24; the protective plate 24 has multiple plates and is respectively disposed on the end face of the base 1, and the multiple protective plates 24 are all cuboid structures.

[0030] In this embodiment, all protective plates 24 are made of transparent acrylic sheets. The protective plates 24 are respectively positioned on the three end faces of the base 1.

[0031] See Figures 3-5 The wire measuring mechanism 2 also includes a rotating plate 25; the rotating plate 25 is rotatably disposed on the end face of the protective plate 24, and the rotating plate 25 can be in contact with the end face of the protective plate 24 by rotating, and the rotating plate 25 has a cuboid structure.

[0032] In this embodiment, both the protective plate 24 and the rotating plate 25 are made of transparent acrylic sheet. Multiple protective plates 24 and rotating plates 25 together form a sealed space that completely encloses the base 1. The rotating plates 25 are fixed together with adhesive, while the rotating plates 25 are rotated relative to the protective plates 24, allowing the rotating plates 25 to close or open. This effectively reduces the possibility of changes in the tilting or bending state of the clamped steel wire due to airflow variations during measurement, thus ensuring accurate detection of the wire's tilting or bending state.

[0033] See Figures 3-5 The wire measuring mechanism 2 also includes a mounting plate 26, a positioning plate 27, and a screw 28. The mounting plate 26 is disposed on the outside of the support plate and is located beside the clamping part 23. The positioning plate 27 is disposed beside the mounting plate 26 and is connected to the mounting plate 26 by fasteners. The screw 28 is rotatably disposed beside the positioning plate 27 and is threadedly connected to the clamping part 23. When the screw 28 rotates, it can drive the clamping part 23 to move.

[0034] In this embodiment, the mounting plate 26 can be installed on top of the support rod 22 using fasteners. Then, the operator installs the positioning plate 27 next to the mounting plate 26. After installation, the positioning plate 27 and the mounting plate 26 are quickly installed using fasteners. After installation, the mounting plate 26 and the positioning plate 27 are located on the top side of the support plate. In this embodiment, there is a pair of clamping parts 23. One clamping part is welded to the positioning plate 27, and the other clamping part 23 is threaded to the screw 28. When the screw 28 rotates, it can drive the clamping part 23 threaded to the screw 28 to move towards the other clamping part 23 until the clamping part 23 fixes the steel wire to be tested, thus completing the fixing work of the steel wire.

[0035] See Figures 3-5 The wire measuring mechanism 2 also includes a guide part 29; the guide part 29 is disposed on the side of the positioning plate 27, and the guide part 29 and the clamping part 23 are in clearance fit, and the clamping part 23 can move along the guide part 29.

[0036] When the clamping part 23 moves, it can move horizontally along the guide part 29.

[0037] See Figures 3-5 The guide part 29 has a cylindrical structure, and both sides of the guide part 29 extend through and to both sides of the positioning plate 27.

[0038] The guide portion 29 is preferably cylindrical, and the guide portion 29 is welded to both sides of the positioning plate 27.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
