Patent number: 9020629Abstract: Loads that act on all the bearings that support a main spindle are derived from a variation in the state of the main spindle and, in addition, raceway surface contact pressures of the respective bearings are analyzed, so it is possible to accurately keep track of the state of each bearing. Then, when the raceway surface contact pressure exceeds a corresponding threshold, a machining condition is changed to execute control such that the raceway surface contact pressure does not exceed the corresponding threshold, and, furthermore, when the raceway surface contact pressure exceeds the corresponding threshold even when the machining condition is changed, the main spindle is controlled to stop, so it is possible to prevent a seizure of each bearing. Thus, it is possible to improve machining accuracy by controlling the main spindle with high accuracy.Type: GrantFiled: September 22, 2010Date of Patent: April 28, 2015Assignee: JTEKT CorporationInventor: Shigeru Matsunaga

Patent number: 7250023Abstract: A tool for a power drill allows fast and convenient loading and unloading of a screw bit, drill bit, or other implement. The user preferably loads the tool with the necessary implements which are then carried with the tool. Each received implement is movable from a storage position to an in use position in drive engagement with the power drill or power screwdriver. The desired implements can rapidly be changed from one to the other, while the implements are retained on the tool.Type: GrantFiled: October 8, 2003Date of Patent: July 31, 2007Inventor: Li Kun Bai

Patent number: 6736767Abstract: A machine tool with a driven tool spindle that is rotatable about a spindle axis that includes a tool exchanger including grippers to displace tool-holders or tools between a receiver position in the tool spindle and a storage position, or vice versa. The tool-holders or tools in these two positions are identically oriented, and the storage position and the receiver position are displaced with respect to each other along the spindle axis direction of the tool spindle. The tool exchanger possesses a transport mechanism that includes a carrier element pivotable about a pivot axis inclined with respect to the spindle axis, to which grippers pivotable about axes perpendicular to each other are connected. Guide elements are mounted so they may be driven and rotate about the first axis parallel to the pivot axis in the opposite direction to the pivot direction of the carrier element are included on the carrier element.Type: GrantFiled: March 11, 2003Date of Patent: May 18, 2004Assignee: Deckel Maho Seebach GmbHInventor: Thorsten Lasch

Patent number: 6527686Abstract: A movable spindle tool machine, such as a printed circuit board line drilling machine includes a base and a spindle mounted to the base. A magazine is mounted proximate the spindle for storing a supply of tools. A pitch independent tool changer is moveably mounted relative to the base for transferring tools from the magazine for insertion into the spindle. A tool locator is mounted in line with the spindle. The tool changer is operable to initially transfer a tool from the magazine to the tool locator to align the tool with the spindle and thereafter transfer the tool to the spindle for insertion into the spindle. The spindle is mounted to a nested outrigger guide. A positioning system can move two or more spindles simultaneously. A bit detector in a pressure foot button uses fiber optics to detect broken bits.Type: GrantFiled: February 2, 2000Date of Patent: March 4, 2003Assignee: International Business Machines CorporationInventors: David Erle Houser, Joseph Duane Kulesza, Candido Tiberia
