Quick-action mandrel for machine tools

This quick-action mandrel enables mandrels to be reduced in size and the internal clamping of workpieces to be simplified. The workpiece with a cylindrical, conical or stepped bore is clamped continuously between conical clamping surfaces on the mandrel and a slip-on clamping sleeve. For narrow workpieces the clamping sleeve is equipped with a supporting member and can be used either way. With the mandrel accommodated between the tips, the clamping sleeve is stopped by means of cross-screws. Clamping members are formed on the clamping sleeve for accommodating pincers. When both tip pressure and clamping pressure are employed the clamping sleeve is accommodated in the pincers and the mandrel together with the workpiece is inserted into the bore of the clamping sleeve. The tip pressure effects a rapid clamping of the workpiece through the tip, mandrel, workpiece and sleeve.

A method and means of locating parts on revolving arbors or mandrels

... 1,014,410. Mandrels. F. HURTH, and H. HURTH. Nov. 24, 1964 [Feb. 4, 1964], No. 47711/64. Headings B3B and B3K. An arbor or mandrel comprises means for applying an eccentric force to a tool or workpiece if it is not running true. A hob 15 is secured by a nut 17 and a collar 16 to an arbor 11 clamped between centres by a draw-bar 14. Due to clearances and lack of complete contact between the faces of the nut and hob, a force may be applied to the tool which causes the arbor to be slightly bowed. The bow is corrected by the rotation of adjusting screws passing axially through the nut. The hob may be clamped solely by the screws. In a modification, the screws 21, Fig. 3, are carried by a collar 22 which is secured by a nut 24 and a spacing sleeve 23. In a further modification, screws 31, Fig. 4, are provided in the collar 30 also. In a further modification, only one screw is provided. In a final modification, the screws are replaced by wedges or keys.

PRESSURIZED CLAMP FOR SECURING TOOLS OR WORKPIECES

A pressurized or hydraulic clamp, with piston reset, for securing tools or workpieces, such as grinding wheels, milling tools, and the like, to a shaft. By pressurizing with a hydraulic fluid, a floating piston is pressed out of the clamping unit to hold the workpieces or tools against a support. In order to retract the piston when the hydraulic pressure is released, the circular piston is provided with a bead on its outside or inside, depending upon the application; the bead is connected to one or more springs. The springs, which are pre-tensioned in the starting position, and are further tensioned when the piston is driven out, automatically reset the piston when the pressure is released.

Disc-chucking mechanism having contractable/expandable O-ring for fixing disc

A chucking mechanism which reliably attaches and detaches a disc with high precision. The chucking mechanism includes a shaft for supporting the disc and having a tapered recess, a tapered cone adapted to fit in the tapered recess, and a piston for moving a rod, attached to the tapered cone, through a hole formed in the shaft. The mechanism also includes an O-ring having a variable diameter and being disposed between the tapered cone and the tapered recess. As the piston moves the tapered cone in a first direction, the tapered cone gradually expands the diameter of the O-ring to press and fix the disc. As the piston moves the tapered cone in a second direction, the diameter of the O-ring gradually contracts to move out of contact with the disc so as to release the disc.

Work-piece clamping unit, comprising windows and inner bore for processing inner and outer surface of object

The work-piece (2), which could be the cage of a ball bearing, is clamped in between a rotating lower element (4) and a coaxial positioned axially movable and rotating upper element (3), both accommodated inside a housing (5). The housing (5) is provided with two windows (7) suitable for the insertion of tools used for the processing of the outer surface of the object (2). A central bore (8) facilitates the insertion of a tool into the center of the work-piece (2) in order to process its inner surface.

Cooling system and method for machine tools

A clamping system for machine tools includes a body portion configured to be received in a holding fixture of a machine, a tool holder integrally formed with and extending longitudinally from the body portion, the tool holder having a mounting mechanism on a distal end thereof for receiving a cutting tool, at least one fluid delivery vein extending through the tool holder from the body portion to the distal end of the tool holder, and at least one outlet at the distal end of the tool holder, the at least one outlet being configured to direct a fluid from the at least one fluid delivery vein toward at least one of the cutting tool and a workpiece.

Chamfering air tool

A chamfering air tool includes a driving shaft rotated by air pressure in a casing, a rotary shaft perpendicularly combined to the driving shaft for rotation, and a cutter fixed to the rotary shaft. Air holes are formed through the rotary shaft in a length direction. Air discharge groove is formed in the cutter. Air hole communicated with the air hole is formed in the fixing bolt head. Air path is formed in the fixing bolt head to keep a predetermined gap from the cutter. Guide ring having a diameter approximate to a lower end of the cutter is rotatably mounted to the fixing bolt head. Thus, air is blown to air hole of the rotary shaft, air hole formed in the fixing bolt head, air path formed between the cutter and the guide ring, and air discharge groove of the cutter, thereby eliminating cut chips and cooling the cutter.

Lens production method and process

A method for processing a first optical face and a second optical face of a lens, where a lens blank is positioned and gripped by a gripping device relying on reference datum indications rendering it possible to obtain topographic orientation for processing both faces of the lens, and wherein not more then one reference datum indication extends on a face of the lens.

Method and apparatus for processing/machining a vehicle wheel/rim preform

A method of processing a vehicle wheel/rim preform with a first rotational axis and having a centersection/spider and an annular wall extending around the centersection/spider and first rotational axis and having an annular surface defining axially spaced, annular inboard and outboard bead seats. The method includes the steps of: providing a workpiece support having a chuck assembly that is rotatable around a second axis and at least one rim wall support assembly; engaging the chuck assembly with the centersection/spider to maintain the vehicle wheel/rim preform in a processing position on the chuck assembly wherein the first rotational axis on the vehicle wheel/rim preform is substantially coincident with the second axis; engaging the at least one rim wall support assembly with the annular wall to exert a force with a radial component upon the annular wall to thereby stabilize the wheel/rim preform; and processing the vehicle wheel/rim preform at the annular surface fully axially between the inboard and outboard bead seats with the vehicle wheel/rim preform maintained in the processing position and rotated by the chuck assembly around the second axis.

Slitter tool locking system

A locking system for securing tools on a slitter arbor. The locking system has a collar attached to the arbor, with the collar spaced from the tooling. A nut is placed over the collar and positioned next to the tools. The nut is then rotated to secure the nut between the collar and the tools.

PORTABLE ELECTRICAL MACHINE TOOL HAVING A FAST CLAMPING DEVICE FOR A WORKING ELEMENT

Une machine-outil électrique portative (10) comportant un dispositif de serrage rapide pour un élément de travail (12) comprend un mandrin de travail destiné à entraîner l'élément de travail, un élément de fixation (13) destiné à fixer l'élément de travail sur l'extrémité du mandrin de travail, et un ensemble de verrouillage. L'élément de fixation comprend un arbre de serrage (32) apte à être introduit dans le mandrin de travail et un ensemble de déplacement destiné à amener l'élément de fixation à se déplacer entre une position de libération et une position de serrage. L'ensemble de verrouillage comprend un composant de serrage apte à flotter, et le composant de serrage et l'arbre de serrage comportent des parties dentées correspondantes, de telle sorte qu'une mise en prise et un désengagement de ceux-ci est obtenu de manière sélective par la rotation relative des parties dentées.
