[0001] The utility model relates to the field of supporting devices for the production of resin - bonded abrasives. More specifically, the utility model relates to a supporting device for the production of resin - bonded abrasives. Background Art

[0002] Resin - bonded abrasives refer to abrasives in which abrasives are adhered to a flexible substrate with an adhesive, also known as flexible abrasives. When making abrasives by adhering abrasives to a flexible matrix (such as cloth or paper) with an adhesive, in order to ensure the flatness of the grinding surface of the abrasive after adhesion, generally, a polishing device is required to polish the surface of the abrasive to ensure the cleanliness of the abrasive surface, so as to ensure that the abrasive can be adhered flatly and firmly to the grinding surface of the mold. However, the existing polishing devices are generally fixedly supported and installed through a support structure, which will be worn during the grinding process of the abrasive, and the polishing parts need to be disassembled and replaced frequently, making it difficult to meet the adaptive fitting requirements of the grinding surface during actual grinding operations. Therefore, a supporting device for the production of resin - bonded abrasives is proposed to solve the above problems. Summary of the Utility Model

[0023] In this embodiment, the coated abrasive is placed on the backing plate 11, and the clamping cylinder 12 is started to drive the second clamping block 13 to fit with the coated abrasive, so as to fix the coated abrasive and prevent it from shaking during grinding.

[0024] Preferably, as another embodiment of the present invention, an annular sliding groove is formed at the top end of the workbench 1, and the bottom end of the backing plate 11 is slidably supported by a plurality of sliding rods 14 in the annular sliding groove.

[0025] In this embodiment, the bottom end of the backing plate 11 is supported by the sliding rods 14. At the same time, when the backing plate 11 rotates, the sliding rods 14 rotate along with the backing plate 11, so as to improve the stability of the backing plate 11 during rotation.

[0026] Preferably, as another embodiment of the present invention, the driving component includes a driving motor 16 arranged below the workbench 1. A main gear 15 is coaxially connected to the output shaft of the driving motor 16. The bottom end of the connecting shaft 18 penetrates downward through the workbench 1, and a sub-gear 17 meshing with the main gear 15 is sleeved and fixed thereon.

[0027] In this embodiment, the driving motor 16 is started to drive the main gear 15 to rotate. The main gear 15 drives the sub-gear 17, so that the connecting shaft 18 drives the backing plate 11 to rotate. When the backing plate 11 rotates, it drives the coated abrasive fixed on the backing plate 11 to rotate, so that the coated abrasive grinds against the grinding part.
