| 20090209356 | Tap Holder - It is an object of the invention to provide a tap holder in which even when an error is brought about in synchronizing spindle feeding and rotation of a tapper body and a tap collet of a tap holder in correspondence with a machine tool spindle, the synchronization can be established by absorbing the error by a simple constitution. As means therefor, the tap holder is characterized in that a tapper body and a tap collet are inserted by a locking member at portions of the tapper body and the tap collet overlapping each other, and the tap collet is fixed to the tapper body by engaging the locking member with at least one of the tap collet and the tapper body in a state of being interposed with an elastic member on both sides thereof in an axial direction X. | 08-20-2009 |
| 20130059669 | Self-synchronizing tap driver for rigid/synchronous tapping with adjustable tension and/or compression - Disclosed is a tap driver for rigid tapping, which includes adjustable tension and compression of the tap driver. In the preferred embodiment, the tap drive is adjustable by rotation of the outer collar between a plurality of settings, each of which provide a different tension or compression in the tap driver. | 03-07-2013 |
| 20090005185 | Tool for the Chipless Shaping Threads, in Particular for the Forming of Internal Threads - A tool for chipless shaping of threads has a working part having an exterior side provided with thread grooves. A clamping shaft having a fastening area is provided and the working part is secured on the fastening area. The working part is a component that is nonpositively secured in an axial direction of the clamping shaft on the fastening area of the clamping shaft. The fastening area of the clamping shaft has a cross-section that is smaller than a cross-section of a remainder of the clamping shaft. | 01-01-2009 |

| 20150328731 | REMOVING/CONNECTING STRUCTURE FOR COMPLEX MATERIAL OF THREADED ROD WORK PIECE AND WASHER - A removing/connecting structure for complex material of threaded rod work piece and washer includes a machine body having abase seat and a rail vertically spaced from the base seat. The rail includes a front section and a rear section spaced from the front section. Each of the front and rear sections is composed of a first rail piece and a second rail piece mated with each other. A sensor unit is disposed between the root section of one of the first and second rail pieces and a main body. A cylinder is disposed under the rear section. A piston rod of the cylinder is disposed under the rear section. A bottom section of the rear section is connected with a fixing section of the cylinder, whereby the rear section is drivable by the piston rod to ascend/descend. The cylinder is connected to the sensor unit by means of signals. | 11-19-2015 |

| 20120046115 | Bolt Thread Damage Prevention Assembly - A bolt thread damage prevention assembly for minimizing thread damage to produced and packaged bolts includes a bolt production assembly, threaded bolts produced by the bolt production assembly, and a bolt tray for receiving the threaded bolts. A drop pan holds the bolt tray. Oil is positioned in the drop pan and a plurality of air jets create turbulence in the oil in the drop pan. The bolt tray is perforated for permitting the oil to enter the bolt tray in a turbulent state. A distribution conveyor belt is positioned to drop the threaded bolts into the bolt tray while the bolt tray is positioned in the drop pan while the oil is in the turbulent state. A collection pan is provided for collecting threaded bolts from the bolt tray. A bolt tray transport assembly moves the bolt tray from the drop pan to the collection pan. | 02-23-2012 |
