The utility model relates to a straight repairing disc structure of double-sided thinning grinding equipment. The straight repairing disc structure comprises a grinding wheel, the device comprises a workbench, the workbench is provided with a lead screw assembly, the lead screw assembly comprises a base and a lead screw body installed on the base, a driving mechanism is installed on one side of the workbench, and an output shaft of the driving mechanism is in transmission connection with one end of the lead screw body through a transmission part; the trimming assembly comprises a first bearing seat installed on the lead screw body and an installation seat installed on the first bearing seat, and a supporting rod coaxial with the lead screw body and parallel to the lead screw body is arranged on one side of the installation seat. According to the grinding wheel trimming device, the lead screw assembly and the driving assembly are arranged and matched with the bearing seat and the mounting plate, a traditional swing arm type trimming disc structure is changed into a linear reciprocating type trimming disc structure, and therefore the phenomenon that the inner circle is high and the outer circle is low when a grinding wheel is trimmed is avoided.

The application discloses a disc repairing machine, which comprises a machine table, a grinding mechanism and a clamping mechanism. The grinding mechanism comprises a driving structure, a supporting and leveling structure and a grinding disc. The driving structure is connected to the machine table and drives the supporting and leveling structure. The supporting and leveling structure comprises a supporting disc and a floating leveling assembly. The supporting disc is drivingly connected to the driving structure. The floating leveling assembly is uniformly arranged on the supporting disc in a circumferential direction. The grinding disc is horizontally installed on the floating leveling assembly. The levelness of the grinding disc is adjusted by controlling the elastic floating amount of the floating leveling assembly at each angle in the circumferential direction. The clamping mechanism comprises a moving structure and a clamping structure. The moving structure is transversely arranged on the machine table. The clamping structure is drivingly connected to the moving structure. The clamping structure comprises an adjusting rod and a centering clamp. The centering clamp is arranged in a prefabricated hole at the center of a disc to be repaired. The adjusting rod is drivingly connected to the centering clamp so that the centering clamp clamps or releases the disc to be repaired. The technical scheme aims to improve the grinding precision of the grinding disc on the disc to be repaired.

The utility model discloses a disc repairing device of a single crystal silicon carbide polishing machine, and relates to the technical field of polishing machines. The device comprises a sliding frame, a sliding column, a driving mechanism, a fixing seat and an adjusting frame, the sliding frame comprises a square sliding sleeve, one end of the square sliding sleeve is fixedly provided with a transmission chamber through a group of side plates, the driving mechanism is arranged at the position of the transmission chamber, and one side, close to the square sliding sleeve, of the transmission chamber is connected with a lead screw. Through the design of the fixing base, the sliding frame can be made to turn over, the buffering effect can be achieved through the design of the adjusting frame, the cushion base, the vertical rod and the spring, meanwhile, the supporting and adjusting effects can be achieved through the design of the cushion rod and the supporting ball, and the fixing effect can be achieved through the design of the fixing lug and the fastening screw; and meanwhile, the angle and the height of the turning tool can be adjusted, so that the application range is widened, and the position stability and the installation accuracy of the disc repairing device are improved.

This utility model discloses a dental handpiece assembly and repair tool, including a repair rotating disk, a disc repair base, and a central support column. The top of the central support column is movably connected to the middle of the repair rotating disk, and the bottom of the central support column is connected to the disc repair base. The repair rotating disk is provided with a first assembly component, a second assembly component, a third assembly component, a first disassembly component, a second disassembly component, and a third disassembly component. The disc repair base is provided with a first worktable, a second worktable, a third worktable, a first assembly base, a second assembly base, and a third assembly base. The advantages are: this design can meet the repair needs of various models of dental handpieces and their various components, thus making the repair more comprehensive, and the disassembly and assembly structure is simple, improving repair efficiency.

The utility model discloses a four-station polishing and grinding machine, and relates to the technical field of polishing and grinding machines. A main shaft mechanism is arranged in the center of the top of the machine body, the output end of the main shaft mechanism is connected with a polishing disc, a driving mechanism connected with the main shaft mechanism is arranged in the machine body, the portal frame comprises a plate seat, a sealing box is fixed to the top of the plate seat, and the plate seat is fixed to the top of the machine body through four supporting stand columns. The plate seat is provided with four ramming head receding grooves facing the axis of the main shaft mechanism. By designing the novel polishing and grinding machine, the four-station polishing and grinding function is achieved, the polishing and grinding efficiency can be greatly improved, meanwhile, the polishing head device and the disc repairing machine are arranged on the portal frame in a centralized mode, the portal frame is located over the machine body, and the polishing head device and the disc repairing machine work vertically and cannot protrude out of the range of the machine body; therefore, the occupied area is reduced, and the normal work of each device is not influenced.

According to the disc repairing device and method, an oval center cam is used for driving a flexible gear to generate periodic deformation waves, fluctuation is transmitted to a special multi-layer composite structure in the flexible gear through differential engagement with a rigid gear, finally, a coating on the surface layer is driven to generate high-frequency micro-amplitude swing, and when the swing is combined with rotation of a polishing pad, the polishing pad is driven to rotate. And a complex net-shaped grinding path is formed, high points on the surface of the polishing pad can be selectively and greatly removed, so that the flatness after finishing is effectively improved, the performance of the polishing pad is uniformly recovered, and the polishing quality of a final silicon wafer is remarkably improved.
