Description

Technical Field

[0001] This utility model belongs to the field of billet technology. Specifically, this utility model relates to an auxiliary device for measuring the curvature of a billet. Background Technology

[0002] According to regulations, the curvature of the billet should be less than 0.6% of its total length. After production, the curvature of the billet needs to be measured to ensure that the quality meets the requirements and that it can be properly sawed by automated equipment. Currently, the calculation of the curvature of the billet is mainly based on the ratio of the chord height of the curved part to the total length of the billet.

[0003] Existing technology mainly measures the length of a straight line and a recessed area by manually pulling a string. The specific operation involves two people pulling a string, while one person measures the distance between the string and the inside of the recess. The curvature is then calculated by comparing the measured length with the total length. This work requires at least three people, resulting in low measurement efficiency and a large workload. Furthermore, the string sags due to gravity during the operation, leading to significant measurement deviations.

[0004] Utility model patent CN218994321U, published on May 9, 2023, discloses a measuring tool entitled "A Measuring Tool for Measuring the Dimensions of High-Temperature Continuous Casting Billets." It includes a display instrument for displaying measurement data, a measuring cylinder on one side of the display instrument, a partition fixedly connected inside the measuring cylinder, forming a movable cavity and a heat-insulating cavity within the measuring cylinder, and a mounting cylinder fixedly connected to one side of the measuring cylinder. A wire encoder for measurement is fixedly installed inside the mounting cylinder, the wire encoder including a measuring wire and a connecting wire, one end of the measuring wire passing through the mounting cylinder and the measuring cylinder and extending into the movable cavity; a measuring mechanism is movably installed inside the movable cavity. However, this measuring tool for measuring the dimensions of high-temperature continuous casting billets does not solve the aforementioned technical problem. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary device for measuring the curvature of cast billets that is simple in structure, saves labor, and is easy and convenient to operate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The auxiliary device for measuring the curvature of the cast billet includes a first magnetic suction plate, on both sides of which are respectively provided an installation sleeve and a positioning plate. A laser pen is provided inside the installation sleeve, and the installation sleeve is connected to an angle adjustment structure.

[0008] The angle adjustment structure includes an adjustment bolt. The mounting sleeve has an open end and a positioning port at both ends, and the laser pointer's emission end extends out of the positioning port. A spring and a nut are fixedly connected to the open end. The spring and nut are arranged opposite to each other. The end of the spring abuts against one side of the laser pointer. The adjustment bolt is threadedly connected to the nut, and the end of the adjustment bolt abuts against the other side of the laser pointer.

[0009] It also includes a second magnetic plate, which is provided with a connector for inserting a measuring ruler.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0023] like Figure 1 As shown, the auxiliary device for measuring the curvature of a cast billet includes a first magnetic plate 2. A mounting sleeve 3 and a positioning plate 7 are respectively provided on both sides of the first magnetic plate 2. A laser pointer 4 is installed inside the mounting sleeve 3, and an angle adjustment structure is connected to the mounting sleeve 3. In the above structure, the first magnetic plate 2 is used to adhere to the cast billet 1. The laser pointer 4 is a commonly used laser pointer. Because the light emitted by the laser pointer 4 forms a straight line on one side of the cast billet 1, the adjusting bolt 8 is used to adjust the emission angle of the laser pointer 4. By using the magnetic plate, the complex measurement process of traditional wire pulling is eliminated, and one person can easily complete the curvature measurement. In actual use, the magnetic plate can also be replaced by a steel plate with a magnet.

[0024] like Figure 4 and Figure 5As shown, the angle adjustment structure includes an adjustment bolt 8, and the mounting sleeve 3 has an open end 5 and a positioning port 6 at both ends. The emission end of the laser pointer 4 extends out of the positioning port 6. A spring 9 and a nut 10 are fixedly connected to the open end 5. The spring 9 and the nut 10 are arranged opposite to each other. The end of the spring 9 abuts against one side of the laser pointer 4. The adjustment bolt 8 is threadedly connected to the nut 10. The end of the adjustment bolt 8 abuts against the other side of the laser pointer 4. The opening 5 is the installation entrance for the laser pointer 4. The diameter of the positioning port 6 is smaller than the diameter of the laser pointer 4's emission end. It not only serves as the emission port for the laser pointer 4's light but also restricts the axial movement of the laser pointer 4. When the spring 9 deforms, the laser pointer 4 changes angle around the positioning port 6. The adjusting bolt 8 can finely adjust the angle of the laser pointer 4. The length of the spring 9 is greater than half the inner diameter of the mounting sleeve 3. When the laser pointer 4 contacts the spring 9, it will tilt and lift under the pressure of the spring 9. Tightening the adjusting bolt 8 compresses the spring 9. During this process, the angle of the laser pointer 4 changes with the tightening of the adjusting bolt 8, that is, the emission angle of the light changes. When the light hits the other end of the casting billet 1, the casting billet 1 is regarded as an arc segment. That is, the distance from one end of the casting billet 1 to the other end constitutes the chord length. The distance between the midpoint of the chord length and the midpoint of the casting billet 1 constitutes the chord height. Since the length of the casting billet 1 is easy to measure, only the chord height needs to be measured to further calculate the curvature. The chord height can be read after the light spot hits the measuring ruler 14.

[0025] like Figure 3 As shown, the auxiliary device for measuring the curvature of the cast billet also includes a second magnetic plate 11. The second magnetic plate 11 is provided with a connector 12, and a measuring ruler 14 is inserted into the connector 12. The second magnetic plate 11 is placed in the middle of the cast billet 1. The second magnetic plate 11 is used to stabilize the position of the measuring ruler 14. It is also magnetically attracted to the outer surface of the cast billet 1. The connector 12 is provided with an open end 5 for mounting the measuring ruler 14. The measuring ruler 14 is used to measure the chord height.

[0026] like Figure 1 As shown, the positioning plate 7 has an arc-shaped structure, the first magnetic suction plate 2 has a planar structure, and the second magnetic suction plate 11 also has an arc-shaped structure. The above magnetic suction plate structures are simple and ensure that they can all fit stably with the casting billet 1.

[0027] like Figure 4 As shown, the mounting sleeve 3 has a welding notch 13 at its end, and the nut 10 is welded to the welding notch 13 on both sides. The welding notch 13 is used to increase the welding area of ​​the nut 10 and improve the welding stability of the nut 10.

[0028] like Figure 2 As shown, both the mounting sleeve 3 and the positioning plate 7 are welded and fixed to the first magnetic plate. These components can be manufactured using discarded parts and fixed by welding, thus reducing manufacturing costs.

[0029] like Figure 1As shown, the first magnetic plate 2 is attached to one end of the billet 1, the positioning plate 7 abuts against one end of the billet 1, and the second magnetic plate 11 is attached to the middle of the billet 1. After arranging the two magnetic plates as described above, measurements can be taken, which is highly efficient and requires no multiple operators.

[0030] like Figure 1 As shown, the measurement method is as follows: The billet 1 is placed horizontally on the ground or on a storage rack. The laser pointer 4 is placed in the mounting sleeve 3 beforehand, so that the spring 9 and the adjusting bolt 8 abut against its two sides respectively. The first magnetic plate 2 is attached to the end of the billet 1 and the adjusting bolt 8 is turned to change the angle of the laser pointer 4, thereby changing the angle of the light. When the light spot emitted by the laser pointer 4 falls on the other end of the billet 1, the adjusting bolt 8 is stopped. At this time, the second magnetic plate 11 is attached to the middle area of ​​the billet 1, so that the measuring ruler 14 blocks the light from the laser pointer 4. The specific value of the light spot hitting the measuring ruler 14 is recorded. At the same time, the second magnetic plate 11 can be moved back and forth on the billet 1 for multiple measurements to reduce measurement deviation or to measure the maximum value. The curvature of the current billet can be calculated according to the ratio of the measured value to the current length of the billet 1, so as to determine whether the quality meets the requirements.

[0031] This auxiliary device for measuring the curvature of the cast billet overcomes the shortcomings of traditional measuring ruler 14, such as inconvenience and low accuracy, by using a magnetic structure, laser pointer 4 to form a positioning line, and adjusting bolt 8 to finely adjust the incident angle of the light source. It reduces the measurement work from 3 people to 1 person, reduces measurement deviation caused by operation, realizes single-person measurement of the curvature of the cast billet 1, reduces the difficulty of operation, and improves measurement efficiency and accuracy.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
