Publication number: 20100127465Abstract: A shank attachment device attaches a core drill to a rotating portion of a drill device and includes an arbor and a shank. The arbor is detachably attachable to the rotating portion. The arbor and the shank are detachably attachable to each other. The shank is detachably attachable to the core drill. A stopper engages a groove of the shank to stop a movement of the shank in an axial direction away from the arbor. A rotational torque of the arbor can be transmitted to the shank by engaging a first engaging portion of the arbor with a first engaged portion of the shank. The shank contacts the arbor to stop the movement of the shank in the axial direction toward the arbor.Type: ApplicationFiled: April 3, 2007Publication date: May 27, 2010Applicant: KABUSHIKI KAISHA MIYANAGAInventor: Masaaki Miyanaga

Publication number: 20090283975Abstract: The invention relates to a junction (14) between two components (10, 12) of a tool system that rotates about an axis of rotation (16), especially for use in machine tools. The junction (14) comprises an at least partially conical seat (18), arranged on the first component (10), which is coaxial to the axis of rotation (16) and which is defined by at least one annular front face (20). The second component (12) carries a coupling part (22) which comprises a coupling pin (24) having a conical surface (32) that is complementary to the conical seat (18) and an annular end face (26) pointing towards the annular front face (20) and, in the coupled state, resting against the same. A tie bolt (36) axially projects beyond the free end of the coupling pin (24) and engages, in the coupled state, in a cavity (38) that is adjacent to the seat (18). The junction also has tensioning means that can be actuated from the exterior for mutually bracing the components (10, 12).Type: ApplicationFiled: May 31, 2007Publication date: November 19, 2009Inventors: Uwe Kretzschmann, Jacek Kruszynski, Benno Spors, Wolfgang Bierl

Publication number: 20090218774Abstract: A safe and quick release device for a tool adapter includes a main body and a combination head. The main body has its front end axially bored with a combination groove with an open end. The combination groove has its opposite sides respectively bored with at least one position-limiting hole having its opposite ends respectively and annularly formed with a first position-limiting portion and a second position-limiting portion. A spherical position-limiting member is slidably disposed in the position-limiting hole and restrictedly positioned therein by the first and the second position-limiting portion. Thus, the position-limiting member is ready made, needless to be especially processed, can easily be in stalled for facilitating assembly and disassembly of the combination head, reducing processing cost.Type: ApplicationFiled: March 3, 2008Publication date: September 3, 2009Inventor: Tien-Lung LIN
