AI Technical Summary

Technical Problem

In existing technologies, wood chips adhere to the sandpaper or sanding material during the sanding process of internal grinding devices for wooden furniture holes, affecting sanding efficiency, and the problem of wood chip splattering has not been effectively solved.

Method used

A hole grinding device was designed, which includes a drilling and grinding component, a splash guard component, and a secondary air intake component. The device uses natural wind to clean wood chips by rotating the drill bit in the opposite direction, and the splash guard component reduces wood chip splashing. The secondary air intake component further cleans the wood chips on the slider.

Benefits of technology

It effectively reduces the adhesion of sawdust to the sanding block, improves sanding efficiency, prevents sawdust from flying, and improves the working environment and processing quality.

Abstract

This application discloses a hole internal grinding device for intelligent manufacturing of wooden furniture, belonging to the field of internal hole grinding. It includes an operating table, with an electric clamp mounted on one upper surface of the operating table, and an electric push rod mounted on the top of the other side of the operating table. A rotary motor is mounted at the bottom of the electric push rod, and a drilling and grinding assembly is mounted at the output shaft of the rotary motor. The drilling and grinding assembly includes a connecting rod, with a drill bit mounted at the bottom of the connecting rod. Multiple through slots are formed inside the drill bit. This application first uses the operating table and electric clamp to clamp and position the wooden furniture, and then uses the drilling and grinding assembly to perform hole opening and internal hole grinding operations. To minimize sawdust adhering to the grinding block during grinding, the drill bit is rotated in the opposite direction, allowing natural air to be discharged upwards through the through slots to clean the sawdust generated during grinding, thus maximizing the removal of sawdust adhering to the grinding block.
