AI Technical Summary

Technical Problem

Traditional tool sharpening machines have low cooling efficiency, and open spray systems cause coolant to splash and evaporate, increasing consumable costs and polluting the environment. They also have difficulty effectively reducing the high temperature inside the tool.

Method used

A cooling channel is set inside the rotating shaft of the cutting blade. Combined with the sealed connection design of the rotating block, fixed sleeve, and inlet and outlet channels in the coolant circulation mechanism, the coolant can be directly circulated into the tool during the cutting process, forming a closed loop circulation.

Benefits of technology

It significantly improves heat dissipation efficiency, avoids coolant splashing and waste, ensures the continuity and stability of cooling effect, and reduces the risk of tool wear and workpiece thermal deformation.

Abstract

The utility model belongs to the technical field of screw machining, and particularly relates to a precise tool sharpener which comprises a device body, a rotary table machine is installed in the middle of the top side of the device body, and four sets of material clamping seats are installed on the rotary table machine. And in combination with the sealing communication design of a rotating block, a fixing sleeve, a liquid inlet channel and a liquid outlet channel in the cooling liquid circulating mechanism, the cooling liquid can directly circulate into the cutter in the cutting process. Cooling liquid is driven by the cooling liquid circulating pump and forms closed-loop circulation between the water tank and the cooling channel through the liquid inlet pipe and the liquid outlet pipe, splashing waste caused by traditional spraying is avoided, and the heat dissipation efficiency is remarkably improved through internal cooling. And meanwhile, stable communication of a cooling liquid channel during rotation of the rotating shaft is ensured through the design of a bearing between the fixing sleeve and the rotating block, the problem of leakage or interruption caused by moving parts in a traditional open type cooling system is solved, and the precise and continuous cooling effect is achieved.
