AI Technical Summary

Technical Problem

The fixed structure of traditional louvered discs leads to low operating efficiency and increased material costs when facing the processing requirements of workpieces of different specifications. Although existing modular louvered discs improve the disassembly and assembly efficiency, it is still necessary to frequently replace louvered discs of different specifications to adapt to the processing of workpieces of multiple specifications.

Method used

It adopts a combination structure of outer and inner discs, and through the axial sliding fit design of the adjusting ring and the connecting cylinder, combined with the mechanical self-locking mechanism of the locking plate and locking rod, the lifting and lowering adjustment of the outer disc can be realized to adapt to the processing needs of workpieces with different diameters.

Benefits of technology

It enables the same louvered disc to be adapted to the efficient processing of workpieces of different specifications, avoids the need to replace consumables, improves work efficiency and reduces production costs, and ensures the vertical stability and safety of the grinding surface.

Abstract

The application relates to the technical field of shutter discs, and discloses a combined shutter disc which comprises an outer disc and an inner disc, the outer disc is sleeved on the outer surface of the inner disc, the bottom of the inner disc is fixedly connected with a connecting cylinder, the connecting cylinder is located on the same axis as the inner disc, the outer surface of the connecting cylinder is slidably sleeved with an adjusting ring, and the outer surface of the adjusting ring is fixedly connected with a group of circumferentially-arranged connecting ribs. The combined shutter disc is designed through the axial sliding cooperation of the adjusting ring and the connecting cylinder, so that the user can realize the lifting of the outer disc through simple operation, the blade group forms a combined working surface, when the lock rod is in the high-position locking state, the inner and outer disc blades form a large-diameter polishing plane, and the efficient machining demand of large workpieces is met; after the adjusting ring is pulled down, the outer disc blades are contracted into the projection range of the inner disc, a precise small-diameter polishing area is formed, and the combined shutter disc can adapt to the operation of precise small workpieces or narrow spaces without replacing consumables.
