Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and in particular to a compact rubber-coated abrasive belt wheel. Background Art

[0002] A belt grinder is a tool used for grinding, finishing and polishing surfaces. It usually consists of a rotating drum or wheel with an abrasive belt. The user can place the workpiece on the drum and then control the force and speed of the grinding by adjusting the machine's settings. The abrasive belt is usually made of a wear-resistant material covered with abrasive particles. In metal processing, belt grinders can be used to remove oxide layers from metal surfaces, remove weld joints, flatten metal surfaces, and perform rough and fine grinding. In order to adapt to different product curvatures, different sizes of abrasive wheels or belts can be replaced as needed.

[0003] However, due to the friction coefficient between the friction wheel and the sanding belt, it is difficult for existing sanding belt machines to be equipped with sanding wheels with a diameter less than 30.00 mm. As a result, many products cannot have small rounded corners polished and can only be achieved by manual polishing, resulting in high labor costs for enterprises.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the purpose of this application is to provide a compact rubber-coated abrasive belt wheel, which aims to reduce the diameter of the abrasive belt wheel, increase the friction coefficient between the transmission rod and the abrasive belt, and prevent the back of the abrasive belt from slipping on the surface of the transmission rod. It prevents the transmission rod from over-grinding the polished surface of the product and solves the technical problem that small-sized abrasive belt wheels easily cause stratification and stepping on the product surface.

[0006] A technical solution adopted by the present application to solve the technical problem is as follows: a compact rubber-coated abrasive belt wheel, comprising:

[0007] A fixed base, the fixed base is used to be installed on the belt sander, and a receiving groove is provided on the fixed base;

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0033] The utility model provides Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a compact rubber-coated abrasive belt wheel is used to be installed on a belt sander and used in conjunction with an abrasive belt to grind, trim and polish the surface of a product. In metal processing, it can be used to remove oxide layers on metal surfaces, remove weld joints, and smooth metal surfaces. And perform rough grinding and fine grinding. In order to adapt to different product curvatures, abrasive belt wheels or belts of different sizes can be configured as needed. Its main structure includes: a fixed base 1 and a transmission rod 2, the fixed base 1 is used to be installed on a belt sander, and a receiving groove 15 is provided on the fixed base 1; the transmission rod 2 is a cylindrical structure, and the transmission rod 2 is movably connected in the receiving groove 15; wherein, the outer wall of the transmission rod 2 is coated with an elastic anti-skid layer 21. In order to better protrude the abrasive belt to facilitate grinding of the curved parts of the product, it is preferred that the transmission rod 2 is movably connected to the edge of the fixed base 1.

[0034] It should be noted that, due to the friction coefficient between the friction wheel and the abrasive belt, it is difficult for existing abrasive belt machines to be equipped with abrasive belt wheels with a diameter less than 30.00mm, which results in many products with small rounded corners that cannot be polished and can only be polished manually to achieve the surface effect, resulting in high labor costs for enterprises. Moreover, an abrasive belt wheel that is too small will cause the polishing surface of the abrasive belt to have a larger curvature and more concentrated pressure, which can easily over-polish the polished surface of the product, causing the product surface to be delaminated.

[0035] In this solution, the outer surface of the transmission rod 2 is coated with an elastic anti-skid layer 21, and the elastic anti-skid layer 21 has anti-skid and elastic effects. The friction coefficient between the transmission rod 2 and the abrasive belt can be increased. When the back of the abrasive belt contacts the surface of the transmission rod 2, the friction between the two is relatively large. In addition, during the grinding process, due to the elastic buffering effect of the elastic anti-skid layer 21, the elastic anti-skid layer 21 can buffer the local impact of the abrasive belt grinding the product. It can prevent the transmission rod 2 from over-polishing the polished surface of the product, causing the problem of stratification on the product surface.

[0036] Furthermore, the fixed base 1 includes: an upper support plate 11, a lower support plate 12, a first connecting member 13 and a second connecting member 14. A first mounting hole 111 is provided at one end of the upper support plate 11, and the upper support plate 11 is sleeved on one end of the transmission rod 2 through the first mounting hole 111; a second mounting hole 121 is provided at one end of the lower support plate 12, and the lower support plate 12 is sleeved on the other end of the transmission rod 2 through the second mounting hole 121. At this time, the forces at both ends of the transmission rod 2 are balanced, and the use is more stable. The lower support plate 12 is provided with a mounting portion 122, and the mounting portion 122 is used for detachable connection to the belt sander; the first connecting member 13 and the second connecting member 14 are arranged in an array, and the first connecting member 13 and the second connecting member 14 form a connecting structure, and the connecting structure is used to connect and fix the upper support plate 11 and the lower support plate 12, and the two ends of the first connecting member 13 and the second connecting member 14 are respectively connected to the upper support plate 11 and the lower support plate 12;

[0037] Among them, the upper support plate 11 and the lower support plate 12 are spaced apart to form a receiving groove 15, and the first mounting hole 111 and the second mounting hole 121 are respectively sleeved on the two ends of the transmission rod 2, so that the upper support plate 11, the lower support plate 12, the first connecting member 13 and the second connecting member 14 form a frame structure.

[0038] Furthermore, connecting shafts 22 are provided at the axis centers of both ends of the transmission rod 2, and bearings 23 are sleeved on the two connecting shafts 22. The transmission rod 2 is movably connected in the first mounting hole 111 and the second mounting hole 121 through the two bearings 23. The transmission rod 2 is configured as a metal material structure, so that it has good structural strength, which can ensure long-term high-intensity polishing operations.

[0039] Furthermore, the diameter of the connecting shaft 22 is smaller than the diameter of the transmission rod 2. A step is formed between the connecting shaft 22 and the rolling portion of the transmission rod 2, so that the bearing member 23 is sleeved on the connecting shaft 22 and can abut on the step, making the connection between the bearing member 23 and the connecting shaft 22 more firm and stable.

[0040] Furthermore, the upper support plate 11 and the lower support plate 12 are parallel to each other. When the transmission rod 2 rotates under high load, the upper support plate 11 and the lower support plate 12 can be subjected to more balanced forces.

[0041] Furthermore, the first connecting member 13 and the second connecting member 14 are both cylindrical structures, and the diameter of the first connecting member 13 and the second connecting member 14 is larger than the diameter of the transmission rod 2. In order to allow the transmission rod 2 to rotate stably, the diameter of the first connecting member 13 and the second connecting member 14 is larger than the diameter of the transmission rod 2. This makes the connection between the upper support plate 11 and the lower support plate 12 more secure, and prevents the upper support plate 11 and the lower support plate 12 from being misaligned, causing the transmission rod 2 to get stuck.

[0042] Furthermore, the elastic anti-skid layer 21 is configured as a rubber structure. The rubber material has good elasticity and a high friction coefficient. Moreover, the rubber material is wear-resistant, thereby ensuring the service life of the transmission rod 2.

[0043] Furthermore, the thickness of the elastic anti-slip layer 21 is configured to be in the range of 3.00 mm to 5.00 mm.

[0044] Furthermore, the diameter size range of the transmission rod 2 is configured to be 13.00 mm to 30.00 mm.

[0045] In summary, the present application provides a compact rubber-coated abrasive belt wheel, which can improve the friction coefficient between the transmission rod 2 and the abrasive belt by coating the outer surface of the transmission rod 2 with an elastic anti-skid layer 21. In addition, due to the elastic buffering effect of the elastic anti-skid layer 21, during the grinding process, the transmission rod 2 can be prevented from causing delamination and stepping on the polished surface of the product.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
