Abstract:
The invention relates to the field of toolings for high-accuracy finishing through-holes and non-through-holes, such as for example for calibration, lapping operations. More precisely the invention refers to a tool-holding system for high-accuracy calibration of the type comprising a driving shaft (2) and a driven shaft (3) mutually connected by two cardan joints (5) and that provides an external cylindrical body (6) supported through bearings (8) by said driving shaft (2). The cylindrical body or liner (6) is closed on its bottom side by a driving bush oscillating in a plane perpendicular to the driven shaft rotation axis ; said oscillations being compensated by elastic means. Axial compensation means for driven shaft movements are also provided. The liner (6) forms a chamber (7) that is kept full of oil.
Abstract:
Eine Spindeleinheit (15) weist eine in einem eigenen Lagergehäuse (21) um ihre Längsachse (22) drehbar gelagerte Arbeitsspindel (16) auf, in der eine Aufnahme (17) für Werkzeuge (18) zur Bearbeitung von Werkstücken (12) vorgesehen ist. Über eine Verstelleinheit (23) wird die Arbeitsspindel (16) im Betrieb gegenüber dem Lagergehäuse (21) automatisch und ansteuerbar verstellt.
Abstract:
Sistema de compensación de la calda del carnero en una máquina herramienta, comprendiendo un carro (1) de 5 traslación vertical, en el que se incorpora el carnero de aplicación, disponiéndose sobre dicho carro (1) al menos una y preferentemente dos placas (2) orificadas, sobre cada una de las cuales se incorpora un patín (3) fijo y unos patines (4) móviles, los cuales se 0 relacionan con una guia de desplazamiento transversal del carnero, de manera que mediante el flexado controlado de las placas (2) se compensa la calda del carnero.
Abstract:
The present invention relates to a tool coupling for rotary tools, which tool coupling is intended to connect a first tool body (5) and a second tool body (7), the tool coupling comprising a male part (1) arranged on the first tool body (5) and a female part (3) arranged on the second tool body (7), the male part (1) and the female part (3) being intended to be in engagement with each other in the operative state of the tool coupling, and that the tool coupling comprises members (20) for applying the male part (1) and the female part (3) an axial, uniting force. Characteristic of the tool coupling according to the present invention is that it comprises members (9, 10, 11, 18) for mutual guiding of the tool bodies (5, 7) in the radial direction (R), and that said members (9, 10, 11, 18) are located on one hand in connection with the circumference of the tool bodies (5, 7), and the other hand in connection with the male part and the female part (1, 3).
Abstract:
A tool comprising a housing having a handle (16) and a distal end wherein the distal end has a spindle (70) and a quick-release chuck (90) A sleeve (610) is disposed about the spindle (70)and is axially movable to open or to close the chuck (90). A trigger (605) is pressed with an index finger to move the sleeve (610).
Abstract:
A coupling device for high speed rotation applications comprised of a first member (112) about a longitudinal axis (114) having a collar (120) integrally attached to a solid base (122) and a second member (130) about a longitudinal axis (114) having a sleeve (136) which is receivable within the collar(120). When the first (112) and second (130) members are rotated, the sleeve (136) expands within the collar (120) to minimize or eliminate any clearance that may exist between the sleeve (136) and collar (120). The coupling device may, among other applications, be utilized for machine tools such as milling cutters.
