Housing. Detailed Implementation

[0028] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] Figure 1 This is a schematic diagram of the steel billet surface descaling and rust removal device provided in an embodiment of this application. The device includes a frame 1 and a grinding assembly mounted on the frame 1.

[0030] For details, see Figure 1 A slide rail 6 is fixedly installed on the upper surface of the frame 1, extending along the length of the frame 1. A sliding seat 2 is slidably installed on the slide rail 6. A drive cylinder 3 is also fixedly installed on the frame 1, with the end of its piston rod fixedly connected to the sliding seat 2, and the direction of movement of the piston rod is parallel to the length direction of the slide rail 6. When the drive cylinder 3 operates, the extension and retraction of its piston rod causes the sliding seat 2 to slide along the slide rail 6. The grinding assembly is mounted on the sliding seat 2 and moves synchronously with it.

[0031] The grinding assembly includes a grinding carriage and a drive mechanism for rotating the grinding carriage about its own axis. See also... Figure 1 The grinding stand includes an upper base 12, a lower base 13, and several support rods 14 fixedly installed between the upper base 12 and the lower base 13. Both the upper base 12 and the lower base 13 have circular cross-sections, and their cross-sectional shapes are identical. The axes of the upper base 12 and the lower base 13 coincide. The support rods 14 are evenly distributed circumferentially between the upper base 12 and the lower base 13. To achieve descaling and rust removal on the surface of the steel billet, a grinding wheel is fixedly installed on the lower end face of the lower base 13.

[0032] In another embodiment, the lower end surface of the lower base 13 is directly set as a frosted surface, that is, the steel billet is directly polished through the lower base 13.

[0033] The aforementioned drive device includes a drive assembly 7 and a transmission assembly 8. The drive assembly 7 includes a housing 20 and a drive motor fixedly mounted within the housing 20. The transmission assembly 8 includes a first drive sprocket, a second drive sprocket, and a transmission chain. The transmission chain is wound around the outside of the first and second drive sprockets, thereby driving them to rotate synchronously. The output end of the drive motor is fixedly connected to the first drive sprocket, and the grinding frame is fixedly connected to the second drive sprocket. Thus, when the drive motor operates, it drives the first drive sprocket to rotate, and through the transmission chain, drives the second drive sprocket to rotate synchronously, thereby causing the grinding frame to rotate around its own axis, achieving the grinding of the steel billet surface.

[0034] For a better option, see [link to previous section]. Figure 3 A mounting base 4 is fixedly installed on the sliding base 2. The mounting base 4 is hinged to the housing 20 via a hinge shaft 5 extending vertically, allowing the entire grinding assembly to rotate left and right around the hinge shaft 5. Simultaneously, two hinge seats 15 are fixedly installed on the side of the housing 20 facing the mounting base 4. These two hinge seats 15 are located on opposite sides of the hinge shaft 5, and the distance between the two hinge seats 15 and the hinge shaft 5 is equal. A horizontally extending insertion rod 17 is hinged within each hinge seat 15. It should be noted that the hinge shaft 5 between the insertion rod 17 and the hinge seat 15 is parallel to the hinge shaft 5 between the mounting base 4 and the housing 20. Correspondingly, two positioning plates 16 are fixedly installed on the mounting base 4, aligned horizontally with the two hinge seats 15. Each positioning plate 16 has a through hole for inserting the insertion rod 17. A return spring 18 is coaxially sleeved on the outside of each insertion rod 17, and the two ends of each return spring 18 are fixedly connected to the adjacent hinge seat 15 and positioning plate 16, respectively. In this way, when the grinding assembly deflects left and right around the hinge axis 5, the two insertion rods 17 will move within the positioning plate 16. At this time, the return spring 18 will be stretched or compressed, thereby buffering and resetting the grinding assembly.

[0035] Understandably, when the grinding rack comes into contact with the surface of the steel billet, the rack will be subjected to lateral impact force due to the potential unevenness or irregularity of the billet surface. At this time, the left and right deflection of the grinding rack and the buffering effect of the return spring 18 effectively prevent damage to the grinding components from impact.

[0036] See Figure 1 and Figure 3 An anti-collision assembly is also provided on the side of the housing 20 facing the grinding frame. This anti-collision assembly includes two anti-collision brackets 11 fixedly mounted on the side of the housing 20. These two anti-collision brackets 11 are located on opposite sides of the grinding frame. Anti-collision rollers 10 are rotatably mounted at the ends of both anti-collision brackets 11.

[0037] It should be noted that the distance between the anti-collision roller 10 and the housing 20 on the side away from the housing 20 is greater than the distance between the grinding frame and the housing 20 on the side away from the housing 20. This ensures that when the grinding assembly comes into contact with other objects, the object will first contact the anti-collision roller 10, thus preventing a collision with the grinding assembly.

[0038] Additionally, a collection box 19 can be detachably installed on one side of the frame 1, located directly below the grinding frame. When the grinding assembly grinds the surface of the steel billet, the resulting debris can fall directly into the collection box 19, facilitating the collection and processing of the debris and ensuring a clean working environment.

[0039] Therefore, the technical solution of this application uses the drive assembly 7 to drive the grinding frame to grind and clean the surface of the steel billet, which has good rust removal effect, high applicability and stability, and can greatly improve the rust removal effect while ensuring rust removal efficiency.

[0040] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
