Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of continuous casting billet grinding equipment, specifically relating to a constant pressure grinding belt and an automatic centering and holding grinding belt grinding head. Background Technology
[0002] Low-magnification inspection of continuous casting is a quality control method that exposes the internal macroscopic defects and solidification structure of continuously cast billets through chemical etching technology. Its core lies in achieving visual assessment of defects through standardized acid etching processes. Before acid etching, the surface of the continuously cast billet must be ground to Ra≤0.1μm to eliminate oxide scale and scratches, ensuring uniform acid etching and accurate defect development.
[0003] Currently, grinding equipment for continuously cast billets is usually fixedly mounted above the billet. The billet is ground as it passes underneath. The cut surface of the billet has slight undulations, which can cause the grinding pressure to be too high or too low. Excessive grinding pressure can lead to localized overheating in the grinding area, causing burns on the surface of the billet and accelerating the wear of the grinding equipment, thus increasing energy consumption. Insufficient grinding pressure can reduce grinding efficiency and fail to effectively eliminate the original defects of the billet.
[0004] Therefore, it is necessary to design a constant pressure grinding belt and an automatic belt centering grinding head that can control the grinding pressure within a certain range to ensure grinding efficiency and effect, in order to solve the current technical problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a constant pressure grinding head for abrasive belts that can control grinding pressure within a certain range, ensuring grinding efficiency and effectiveness.
[0006] The technical solution of this utility model is as follows: a constant pressure grinding belt and an automatic centering and holding grinding head for grinding belts, including a mounting plate and a frame. The frame is provided with a grinding mechanism and a tensioning mechanism. One bottom side of the frame is hinged to one side of the mounting plate. A pressure cylinder and a tension spring are provided between the top of the mounting plate and the top of the frame. One end of the pressure cylinder is hinged to the mounting plate, and the other end of the pressure cylinder is hinged to the frame. The grinding mechanism has an active roller rotatably mounted on one side of the lower end of the frame, a drive assembly for driving the active roller to rotate is mounted on the frame, a corresponding driven roller is rotatably mounted above the active roller, an abrasive belt is fitted around the active roller and the driven roller, a roller support is mounted below the driven roller, and the driven roller is rotatably mounted in the roller support.

[0007] Furthermore, one side of the first end of the tensioning arm has a hinge rod that is hinged to the frame, and the other side of the first end of the tensioning arm has a drive rod, and the second end of the tensioning cylinder is hinged to the drive rod; The roller support is rotatably connected to the second end of the tensioning arm, and the tensioning arm is provided with a centering and holding mechanism that applies rotational torque to the roller support.

[0015] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0016] like Figures 1 to 3 As shown, a belt grinding head with constant pressure and automatic belt centering is disclosed, including a mounting plate 1 and a frame 2. A grinding mechanism 6 and a tensioning mechanism 5 are mounted on the frame 2. One bottom side of the frame 2 is hinged to one side of the mounting plate 1. A pressure cylinder 3 and a tension spring 4 are disposed between the top of the mounting plate 1 and the top of the frame 2. One end of the pressure cylinder 3 is hinged to the mounting plate 1, and the other end is hinged to the frame 2. The grinding mechanism 6 has a drive roller 61 rotatably mounted on one side of the lower end of the frame 2. A drive assembly for driving the drive roller 61 to rotate is disposed on the frame 2. A driven roller 62 is rotatably mounted above the driven roller 61. A sanding belt 63 is fitted around the driven roller 62 and the driven roller 62. A roller bracket 68 is mounted below the driven roller 62, and the driven roller 62 is rotatably mounted in the roller bracket 68. The tensioning mechanism 5 has a tensioning arm 51. One side of the first end of the tensioning arm 51 is hinged to the frame 2. A tensioning cylinder 52 is mounted between the other side of the first end of the tensioning arm 51 and the frame 2. The roller bracket 68 is mounted at the second end of the tensioning arm 51. The first end of the tensioning cylinder 52 is hinged to the frame 2, and the second end of the tensioning cylinder 52 is hinged to the tensioning arm 51.
[0017] In the above embodiment, the tension spring 4 is used to balance the weight of moving parts such as the grinding mechanism 6 and the frame 2. The pressure cylinder 3 is set between the upper end of the frame 2 and the mounting plate 1. The pressure cylinder 3 applies a stable thrust to the grinding mechanism 6 to control the grinding pressure within a certain range, ensuring grinding efficiency and effect. The tension cylinder 52 applies a thrust to the tension arm 51. The thrust acts on the driven roller 62 through the roller bracket 68, keeping the abrasive belt in a taut state and ensuring grinding accuracy and efficiency. Both the pressure cylinder 3 and the tension cylinder 52 are adjustable cylinders, and the appropriate pressure can be adjusted according to actual needs.
[0018] In some embodiments, the first end of the tensioning arm 51 has a hinge rod 511 hinged to the frame 2 on one side, and a drive rod 512 on the other side of the first end of the tensioning arm 51. The second end of the tensioning cylinder 52 is hinged to the drive rod 512. The roller bracket 68 is rotatably connected to the second end of the tensioning arm 51. The tensioning arm 51 is provided with a centering and holding mechanism 7 that applies a rotational torque to the roller bracket 68. The centering and holding mechanism 7 applies a rotational torque to the roller bracket 68, causing the sanding belt 63 to be centered on the driven roller 62, thus preventing the sanding belt 63 from shifting during operation.
[0019] As one specific embodiment of the above-mentioned centering and holding mechanism 7, the centering and holding mechanism 7 has a cylinder bracket 71 disposed on the top of the drive rod 512, and a centering cylinder 72 disposed on the cylinder bracket 71. The first end of the centering cylinder 72 is rotatably connected to the cylinder bracket 71, and the second end of the centering cylinder 72 is hinged to the roller bracket 68. The thrust output by the centering cylinder 72 acts on the roller bracket 68, causing the roller bracket 68 to have a tendency to rotate. Once the sanding belt 63 becomes loose, the roller bracket 68 will drive the driven roller 62 to deflect, so as to keep the sanding belt in a centered state on the driven roller 62.
[0020] In some embodiments, the drive assembly has a drive motor 64 fixedly mounted in the frame 2. The output end of the drive motor 64 is provided with a drive wheel 65, and one end of the drive roller 61 is provided with a driven wheel 66. The drive wheel 65 and the driven wheel 66 are connected by a belt 67. After the drive motor 64 is started, it drives the drive wheel 65 to rotate. The drive wheel 65 drives the driven wheel 66 to rotate through the belt 67. The driven wheel 66 drives the drive roller 61 to rotate. The drive roller 61 drives the sand belt 63 to rotate to perform grinding on the continuously cast billet.
