Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical polishing technology, and specifically relates to a mechanical polishing device. Background Technology
[0002] Metal products such as steel pipes, steel plates, and sheet metal often produce raised weld scars after welding. For subsequent installation and aesthetic purposes, these scars need to be ground. Traditional grinding methods typically involve manually grinding around the weld scars with an angle grinder. This method has relatively poor grinding precision, and the varying grinding techniques and pressure applied by different workers can lead to significant product variations. Therefore, fixed grinding devices are generally more effective. Existing fixed grinding machines are usually belt grinders, driven by a motor. Different products require different belt tension adjustments. The belt adjustment methods in existing grinding devices are complex, expensive, and difficult to maintain. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0021] Example 1:
[0022] A mechanical polishing device, such as Figure 1 , Figure 2 and Figure 3 As shown, the assembly includes a drive motor 7, a fixing component 1, a transmission wheel set, a sanding belt 6, and an adjustment component. The transmission wheel set includes a first transmission wheel 2 and a second transmission wheel 3, both of which are mounted on the fixing component 1 and located on the same side of the fixing component 1. The drive motor 7 is connected to the first transmission wheel 2 and located on the other side of the fixing component 1. The rotation of the drive motor 7 drives the first transmission wheel 2 to rotate. The sanding belt 6 is fitted onto the first transmission wheel 2 and the second transmission wheel 3. The drive motor 7 drives the sanding belt 6 to rotate, thereby enabling sanding operations. The adjustment component is mounted on the fixing component 1 and located between the first transmission wheel 2 and the second transmission wheel 3. The adjustment component abuts against the inner side of the sanding belt 6 to adjust the tension of the sanding belt 6 to meet the sanding requirements of different product parts. The fixing component 1 includes a limiting plate 13, a connecting plate 12, and a support plate 11. The connecting plate 12 is mounted on the support plate 11 and located on the same side of the fixing component 1. In the middle of the support plate 11, the limiting plate 13 is set at the end of the connecting plate 12. The limiting plate 13 is set parallel to the support plate 11. The first transmission wheel 2 and the second transmission wheel 3 are both set on the connecting plate 12. The drive motor 7 is also set on the connecting plate 12. A connecting member 8 is set between the drive motor 7 and the connecting plate 12. The connecting member 8 is an L-shaped plate structure. The connecting member 8 is connected to the connecting plate 12 and the limiting plate 13 respectively by screws to fix the drive motor 7. The top of the first transmission wheel 2 and the second transmission wheel 3 is higher than the top of the connecting plate 12, so that the surface of the sanding belt 6 can protrude above the limiting plate 13, which is convenient for grinding the product. In addition, the workpiece to be ground can be placed on the limiting plate 13, and the limiting plate 13 provides a certain support for the workpiece. Multiple fixing bolts are set on the support plate 11. The fixing bolts are used to fix the fixing component 1. The support plate 11 is connected to the worktable by fixing bolts.
[0023] Example 2:
[0024] This embodiment further defines the adjustment component based on the above embodiments, such as... Figure 1 and Figure 2 As shown, the adjustment assembly includes an adjustment rod 5 and a guide wheel 4. The adjustment rod 5 passes through the connecting plate 12, and the guide wheel 4 is located at the end of the adjustment rod 5 and between the first transmission wheel 2 and the second transmission wheel 3. The guide wheel is rotatably connected to the end of the connecting rod. When the sanding belt 6 rotates, it can drive the guide wheel to rotate, and the guide wheel can adjust the tension of the sanding belt 6. The connecting plate 12 is provided with an adjustment groove 121, and the adjustment rod 5 slides in the adjustment groove 121. The adjustment groove 121 has a stepped structure with three adjustment gradients, which can adjust the tension of the sanding belt 6 according to the sanding requirements of the product. The adjustment rod 5 is provided with a first nut and a second nut, which are respectively located on the left and right sides of the connecting plate 12. The first nut and the second nut cooperate to fix the adjustment rod 5. When it is necessary to adjust the sanding belt 6, loosen the first nut or the second nut to make the adjustment rod 5 slide up or down in the adjustment groove 121, so that the guide wheel 4 stretches or prevents the sanding belt 6 from loosening. After adjusting to the appropriate gradient, tighten the first nut or the second nut to fix the guide wheel 4. The other parts of this embodiment are the same as those in the above embodiments, and will not be repeated here.
[0025] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this utility model does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
