Metalworking dust collection attachment and grinding tool

Abstract

Grinding chips generated during metalworking are collected, and dust is collected using a dust collector. A metalworking dust collection attachment removably attachable to a grinding tool including a tip tool includes a suction port that collects grinding chips generated during grinding with the tip tool, and a collector connected to the suction port to collect the grinding chips sucked into the suction port. The collector cools the grinding chips.

What is claimed is: 
     
         1 . A metalworking dust collection attachment removably attachable to a grinding tool including a tip tool, the attachment comprising:
 a suction port configured to collect grinding chips generated during grinding with the tip tool; and   a collector connected to the suction port to collect the grinding chips sucked into the suction port, the collector being configured to cool the grinding chips.   
     
     
         2 . The metalworking dust collection attachment according to  claim 1 , further comprising:
 a connector located at a downstream end of the collector, the connector being connectable to a dust collection hose.   
     
     
         3 . The metalworking dust collection attachment according to  claim 1 , wherein
 the collector includes a cyclone assembly configured to whirl the grinding chips inside the collector to cool the grinding chips.   
     
     
         4 . The metalworking dust collection attachment according to  claim 1 , further comprising:
 a connection channel between the suction port and the collector.   
     
     
         5 . The metalworking dust collection attachment according to  claim 4 , wherein
 the suction port, the collector, and the connection channel each comprise a heat-resistant material.   
     
     
         6 . The metalworking dust collection attachment according to  claim 1 , wherein
 the collector is removably attachable to a handle holder located on the grinding tool.   
     
     
         7 . The metalworking dust collection attachment according to  claim 1 , wherein
 the collector includes a discharge port to be open or closed to allow discharging of the grinding chips.   
     
     
         8 . The metalworking dust collection attachment according to  claim 1 , wherein
 the suction port is integrally attachable to a cover attached to the grinding tool to cover the tip tool.   
     
     
         9 . A grinding tool, comprising:
 the tip tool; and   the metalworking dust collection attachment according to  claim 1  attached to the tip tool.   
     
     
         10 . The metalworking dust collection attachment according to  claim 2 , wherein
 the collector includes a cyclone assembly configured to whirl the grinding chips inside the collector to cool the grinding chips.   
     
     
         11 . The metalworking dust collection attachment according to  claim 2 , further comprising:
 a connection channel between the suction port and the collector.   
     
     
         12 . The metalworking dust collection attachment according to  claim 3 , further comprising:
 a connection channel between the suction port and the collector.   
     
     
         13 . The metalworking dust collection attachment according to  claim 11 , wherein
 the suction port, the collector, and the connection channel each comprise a heat-resistant material.   
     
     
         14 . The metalworking dust collection attachment according to  claim 12 , wherein
 the suction port, the collector, and the connection channel each comprise a heat-resistant material.   
     
     
         15 . The metalworking dust collection attachment according to  claim 2 , wherein
 the collector is removably attachable to a handle holder located on the grinding tool.   
     
     
         16 . The metalworking dust collection attachment according to  claim 3 , wherein
 the collector is removably attachable to a handle holder located on the grinding tool.   
     
     
         17 . The metalworking dust collection attachment according to  claim 4 , wherein
 the collector is removably attachable to a handle holder located on the grinding tool.   
     
     
         18 . The metalworking dust collection attachment according to  claim 5 , wherein
 the collector is removably attachable to a handle holder located on the grinding tool.   
     
     
         19 . The metalworking dust collection attachment according to  claim 2 , wherein
 the collector includes a discharge port to be open or closed to allow discharging of the grinding chips.   
     
     
         20 . The metalworking dust collection attachment according to  claim 3 , wherein
 the collector includes a discharge port to be open or closed to allow discharging of the grinding chips.
