Description

Technical Field

[0001] This invention relates to the field of iron and steel metallurgy technology, specifically to a steel ingot center positioning device and method. Background Technology

[0002] In the steel metallurgical industry, round semi-finished steel ingots need to be processed. Locating the center of these ingots is a crucial step in the machining process. Steel mills typically locate the center by measuring the distance between the positioning surfaces on a lathe and calculating the distance from the positioning surfaces to the machine tool center. However, measuring the distance between the positioning surfaces introduces minute errors, which accumulate and amplify, leading to a significant deviation in the final determined center position. This process is not only cumbersome but also inefficient and inaccurate. Furthermore, the lack of a dedicated device for center positioning necessitates manual measurement, which can be influenced by the operator's subjective judgment and skill level. Different operators may have different measurement habits and technical abilities, resulting in variations in measurement results. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of a steel ingot center positioning device and method provided by the present invention.

[0038] Example 1:

[0039] Combination Figure 1 , Figure 2 as well as Figure 7As shown, the present invention provides a steel ingot center positioning device, including a body 100 as the carrier of the entire device, a base 101 for driving the copper ingot to rotate on the body 100, and a marking mechanism 200 for positioning the center position of the steel ingot. By drawing two straight lines, the center position determined by the intersection point is more accurate, which can improve the measurement accuracy and quickly and accurately determine the center position of steel ingots of different sizes. The body 100 is also provided with a transmission mechanism 300 for automatic positioning. Automated operation can greatly improve work efficiency without manual intervention. The device can determine the center point of multiple steel ingots at the same time, saving human resources and time costs.

[0040] The marking mechanism 200 includes sliding columns 202 fixed to both sides of the body 100. A ruler 201 is fixed between the two sliding columns 202. A transmission groove 216 is opened on the ruler 201. A connecting rod 203 is slidably connected to the transmission groove 216. A pen tip 204 for marking the center position is fixed to the end of the connecting rod 203. The pen tip 204 on the connecting rod 203 can slide along the transmission groove 216 on the ruler 201. By aligning the device with the surface where the steel ingot is positioned, a straight line is drawn arbitrarily along the ruler 201. Then, the steel ingot is rotated, and the pen tip 204 draws another straight line. The intersection of the two straight lines can determine the center of the steel ingot. The center point of the steel ingot can be quickly determined by drawing two straight lines on the steel ingot and finding their intersection, eliminating other complicated measurement steps.

[0041] Specifically, transmission sleeves 205 are fixedly connected to both sides of the base 101. A connecting column 207 is slidably connected to the transmission sleeve 205. A positioning plate 208 is fixedly connected to the end of the connecting column 207. A spring a206 is fixedly connected to the inner wall of the connecting column 207 and the transmission sleeve 205. When the steel ingot is placed in the middle of the base 101, the spring a206 presses the connecting column 207 to move forward. The connecting column 207 moves with the positioning plate 208. The two positioning plates 208 push the steel ingot to the middle position, so that the steel ingot and the pen tip 204 are in the same center position, which can quickly and accurately push the steel ingot to the middle position.

[0042] Furthermore, the positioning plate 208 is an arc shape corresponding to the steel ingot, and a protective layer is provided on the inner side of the positioning plate 208 to avoid damaging the steel ingot.

[0043] As can be seen from the embodiments, the device is simple and intuitive to use, requiring no complicated tools or techniques, and can be easily used by anyone. This makes it more convenient and feasible to determine the center point of a steel ingot, and it is applicable to steel ingots of various sizes and shapes, meeting different measurement requirements. Whether it is a small or large steel ingot, the device can be used to determine the center point.

[0044] Example 2:

[0045] Combination Figure 1 , Figure 3 and Figure 4 As shown, based on Embodiment 1, the transmission mechanism 300 includes a connecting frame 303 slidably connected to the machine body 100, a connecting rod 203 mounted on the connecting frame 303, transmission frames 304 slidably connected to both sides of the machine body 100, a load-bearing shaft rotatably mounted on both sides of the machine body 100, a spur gear 307 fixedly connected to the end of the load-bearing shaft, and a rack 306 corresponding to the adjacent spur gear 307 fixedly connected to the end of the transmission frame 304. A transmission block 305 for alternately pushing the racks 306 on both sides is fixedly mounted on the connecting frame 303. The two transmission frames 304 are symmetrically distributed, and the two racks 306 and the spur gear 307 on the same side are staggered. A connecting shaft 308 is rotatably mounted on the bottom of the machine body 100. A bevel gear 312 for meshing transmission is mounted on the load-bearing shaft and the connecting shaft 308. A drive assembly for simultaneously driving multiple steel ingots to rotate is provided on the connecting shaft 308. First, the connecting frame 303 drives the connecting... As rod 203 moves, pen tip 204 moves along with connecting rod 203. Then, pen tip 204 contacts the upper surfaces of multiple steel ingots in sequence. Subsequently, transmission block 305 on connecting frame 303 contacts transmission frame 304, pushing it to one side. Rack 306 moves with transmission frame 304. Rack 306 drives load shaft to rotate via spur gear 307. Load shaft drives connecting shaft 308 to rotate via bevel gear 312. This, in turn, drives multiple bases 101 to rotate via drive assembly. The steel ingots rotate with bases 101. Then, connecting frame 303 drives pen tip 204 to move to the other side, allowing a second line to be drawn on multiple steel ingots. This simultaneously determines the center of multiple steel ingots. Through the contact and movement of multiple steel ingots, more measurement data can be obtained, improving the accuracy of the center position. Simultaneously determining the center positions of multiple steel ingots allows for comparison and verification, further improving the reliability of the measurement.

[0046] Specifically, the drive assembly includes a worm gear 309 mounted on a connecting shaft 308, a rotating shaft 310 fixedly connected to the base 101 and rotatably connected to the machine body 100, and a worm wheel 311 fixedly connected to the end of the rotating shaft 310 and meshing with the worm gear 309 for transmission. The worm gear 309 rotates with the connecting shaft 308, and the worm gear 309 drives the rotating shaft 310 to rotate through the worm wheel 311. The base 101 rotates with the rotating shaft 310, which can simultaneously drive multiple steel ingots to rotate, facilitating the subsequent drawing of another line. By using a single power source, the manufacturing cost of the device can be reduced. The center positions of multiple steel ingots can be determined simultaneously in one operation, greatly improving the measurement efficiency. It is not necessary to measure each steel ingot individually, saving time and manpower.

[0047] Furthermore, a motor 301 is fixedly mounted on the machine body 100, and a lead screw 302 is fixedly connected to the end of the motor 301. A connecting frame 303 is threadedly connected to the lead screw 302. When the motor 301 is started, it drives the lead screw 302 to rotate, which in turn drives the connecting frame 303 to move and perform the marking operation.

[0048] As can be seen from the embodiment, while the connecting shaft 308 rotates, the bevel gear 312 on the other side also drives another load shaft to rotate. The spur gear 307 rotates with the load shaft, and the rotation of the spur gear 307 drives the rack 306 to move. Then the transmission frame 304 on the other side can be moved in the opposite direction. By repeating the above steps, the device can repeatedly determine the position of the center of multiple steel ingots.

[0049] Example 3:

[0050] Combination Figure 1 , Figure 5 and Figure 6 As shown, based on Embodiment 1, a load-bearing sleeve 209 is fixedly connected to the end of the connecting frame 303. The connecting rod 203 is slidably connected to the load-bearing sleeve 209. A connecting plate 210 is fixedly connected to the connecting rod 203 and slidably connected to the load-bearing sleeve 209. A spring b211 is fixedly connected to the bottom of the connecting plate 210 and the load-bearing sleeve 209. The machine body 100 is provided with multiple guide plates 213 for the pen tip 204 to contact the surface of the steel ingot. A ball 212 located on the same plane as the guide plate 213 is fixedly connected to the connecting rod 203. The pen tip 204 is located above the steel ingot. The load-bearing sleeve 209 moves with the connecting rod 203, and the ball 212 on the connecting rod 203 moves along the guide plate 213, enabling movement. When the pen tip 204 reaches the ingot position, it descends to contact the ingot surface. After the marking is completed, the ball 212 moves to one side of the guide plate 213, and then the spring b211 pushes the connecting plate 210 to rise. The connecting rod 203 rises with the connecting plate 210, and the connecting rod 203 drives the pen tip 204 to detach from the ingot. Repeating the above steps allows for marking the next ingot. This avoids the pen tip 204 from contacting the edges of the ingot during its movement, preventing wear on the pen tip 204 and improving its service life. It also allows for more accurate marking operations, avoiding marking deviations caused by poor contact or offset, and improving the accuracy of measurement and marking.

[0051] Specifically, the guide plate 213 is an inverted frustum shape, and the two corners of the guide plate 213 are rounded. The ball 212 moves along the outer wall of the guide plate 213, and the pen tip 204 can rise or fall at the corresponding position to achieve precise drawing.

[0052] Furthermore, multiple guide plates 213 are fixedly connected by connecting strips. A screw 214 is rotatably mounted on the ruler 201, and a connecting sleeve 215 is threaded onto the screw 214. The connecting sleeve 215 is slidably connected to the ruler 201. The guide plates 213 are fixedly connected to the connecting sleeve 215. Rotating the screw 214 can move the connecting sleeve 215, and the guide plates 213 move with the connecting sleeve 215. This allows the pen tip 204 to be adjusted according to the different heights of the steel ingots, making it easier to determine the center position of steel ingots of different heights.

[0053] As can be seen from the embodiments, by bringing the pen tip 204 into contact with the surface of the steel ingot during the marking process, contact between the pen tip 204 and the edges of the steel ingot is avoided during movement, thereby reducing wear on the pen tip 204. This helps to extend the service life of the pen tip 204 and reduce the frequency of replacement and maintenance.

[0054] Example 4:

[0055] Combination Figures 1-7 As shown, based on Embodiment 1, a steel ingot center positioning device and its usage method are described below:

[0056] S1. First, the staff places the steel ingot on the base 101.

[0057] S2. Subsequently, the pen tip 204 on the connecting rod 203 can slide along the transmission groove 216 on the ruler 201. By aligning the device with the surface where the steel ingot is positioned, the pen tip 204 contacts the surface of the steel ingot and draws the first straight line on the steel ingot along the ruler 201.

[0058] S3. Rotate the steel ingot and move the pen tip 204 in the opposite direction to draw another straight line on the surface of the steel ingot. The intersection of the two straight lines can be used to determine the center of the steel ingot.
