The invention discloses a rotary driven tool holder for inner hole machining. The rotary driven tool holder comprises a tool holder body. The tool holder body is connected with a machine tool rotary driven tool tower through a tool tower connecting opening. A transmission shaft is arranged in the tool holder body in the vertical direction. One end of the transmission shaft is provided with a needle bearing. The middle of the transmission shaft is provided with a deep groove ball bearing. The other end of the transmission shaft is provided with a synchronous toothed belt wheel. The synchronous toothed belt wheel is connected with a power head assembly through a synchronous toothed belt. The power head assembly is provided with a tool through fastening screws. By means of the rotary driven tool holder for inner hole machining, the technological difficult problem of inner wall deep hole machining is smoothly solved, conveying is achieved by using the synchronous toothed belt, manufacturing of the depth of machined holesis simpler than manufacturing of the depth of structures of other gear transmitting, stalling does not exist, the length is flexibly controlled, and lubricant demands are greatly reduced, when the tool rotates, axial jumping and radial jumping are controlled at 0.005 mm, therefore, machined components are high in precision, the service life of the tool is long, and the rotary driven tool holder for inner hole machining is an ideal rotary driven tool holder special for inner hole machining.
Description
technical field [0001] The invention relates to a power tool seat, in particular to a power tool seat for inner hole processing. Background technique [0002] Many new special shape parts are increasing, and the trend of integrating multiple parts into single parts is becoming more and more obvious. The current commonly used processing methods can no longer meet these new processing requirements, for example: 1. In the cylindrical hole of Ф75X80-300, drill from the inside to the outside; 2. In the cylindrical hole of Ф75X80-300, milling blind Hole keyway; 3. In the cylindrical hole of Ф75X80-300, the helix with large pitch is milled. In the long-term practice in the field of mechanical processing, the inventor often encounters the problem of hole processing, especially in deeper holes. Drill stepped holes and countersunk holes on the inner wall outwards. Mill keyways in blind holes. Milling multiple helical grooves in the hole. However, the current processing methods can...
