Patent number: 8920081Abstract: An interface between a receptacle body and an insert designed, in particular, as a tool or workpiece insert, comprises a receptacle body (2) having a cylindrical receiving bore (4), which is circumscribed by a first plane surface (6) extending at a right angle to the bore axis and in which a first cone surface (9) is arranged, said first cone surface being coaxial with the bore axis and being arranged so that its tapered end faces toward the plane surface. The insert (3) has a pin (15) that is disposed to be plugged into the receiving bore (4) and is circumscribed by a second plane surface (22). At an axial distance from the second plane surface (22), said pin has a second cone surface (22), the tapered end of said second cone surface being arranged so as to face toward the second plane surface.Type: GrantFiled: September 22, 2010Date of Patent: December 30, 2014Assignee: ESA Eppinger GmbHInventor: Manfred Neumeier

Patent number: 8037791Abstract: A tool clamping device having a tool holder (2) holding a tool (7, 8) for insertion into a socket of a tool support (1), such as a turret disc is designed such that a receiving body (16) of the tool holder and the tool support (1) have bearing surfaces (16, 3) to be arranged to one another and devices (14, 15) for fastening the tool holder on the tool support. The receiving body or the tool support has at least one stopping means (28), which projects axially over its bearing surface and is disposed on one side of the receiving body or tool support. The tool support or the receiving body has at least one contact surface for the stopping means. There is provided elastic means (36, 44) by means of which the stopping means can be laterally held in place on the contact surface under prestress.Type: GrantFiled: November 26, 2008Date of Patent: October 18, 2011Assignee: ESA Eppinger GmbHInventor: Manfred Neumeier

Patent number: 7913595Abstract: A clutch device for tool holders or tool chucking or workpiece chucking devices is used for the releasable form-fitting engagement of a drive shaft, comprising a spindle of the tool holder or chucking devices, said spindle being coaxial with the drive shaft. The drive shaft and the spindle have separate dog elements, whereby, between the two dog elements, a clutch element is arranged that compensates for alignment errors between the drive shaft and the spindle and that can be moved in a limited manner between the drive shaft and the spindle. The clutch element is in form-fitting engagement with the dog elements of the drive shaft and of the spindle.Type: GrantFiled: January 17, 2008Date of Patent: March 29, 2011Assignee: ESA Eppinger GmbHInventor: Manfred Neumeier

Patent number: 7802950Abstract: A tool clamping insert has a tool holder for receiving a tool shank. The tool holder hole is nominally smaller than the tool shank to be therein but upon heating of the insert expands to a size permitting insertion of the tool shank and, upon cooling, shrink fitting therein. The insert has an external clamping surface and is positioned in a clamping unit. The clamping surface and the tool holder hole are each configured with diameters, external and internal respectively, that change along the progression of their axial lengths.Type: GrantFiled: August 11, 2006Date of Patent: September 28, 2010Assignee: ESA Eppinger GmbHInventor: Manfred Neumeier

Patent number: 7509719Abstract: In a device on machines, especially machine tools and their parts, such as tool holders comprising at least one rotating element, which is rotatably mounted at least in one bearing position arranged in a housing, a lubricating device is provided for this bearing position. For this, the bearing position is located in a lubricant path, which extends from an inlet to an outlet in the housing and into which there is fed under pressure a lubricant mist, which flows through the lubricant path up to the outlet. The outlet is connected to condensation means for the residual quantity of lubricant mist reaching the outlet, so that only condensed lubricant escapes to the outside. The lubricant mist flowing through the housing effects lubrication and cooling of the bearing position and at the same time effects a pneumatic seal of the housing to the outside to prevent contaminants from penetrating.Type: GrantFiled: September 7, 2006Date of Patent: March 31, 2009Assignee: ESA Eppinger GmbHInventor: Manfred Neumeier
