| A machine tool comprises a spindle head displaceable in two orthogonal directions. The spindle head supports a plurality of main spindles and at least one common central driving gear. The spindle head is suspended by means of three flexible rods and a stationary main drive motor is coupled to the driving gear via a flexible shaft.To be used for milling recesses into plastic cards, the recesses being dimensioned to receive electronic chips. | ||||||
| 182 | Machine tool apparatus and linear motion track therefor | US134524 | 1993-10-07 | US5472367A | 1995-12-05 | Alexander H. Slocum; John H. Olsen |
| A machine tool apparatus, and a linear motion track therefore, are disclosed where the linear motion track is comprised of a tube having a circular cross-section with at least two bearings longitudinally disposed on opposite exterior sides of the tube such that the tube forms a pair of arches joined by the two bearings. The tube arches minimize localized bending moments when radial or moment loads are applied to the tube arches through the bearings and from the longitudinally slidable carriage on the tube. In addition to the linear motion track, the machine tool apparatus also includes a table, for supporting a workpiece, to which the linear motion track is attached, and a machine tool attached to the linear motion track. | ||||||
| 183 | X-Y-Z drive apparatus | US901354 | 1992-06-19 | US5265491A | 1993-11-30 | Yasuo Nishiumi |
| An X-Y-Z positioning apparatus includes an X table which may move along an X axis and a Y table which is mounted on the X table and movable along a Y axis. A pair of guide rails is provided on the X table and a pair of sliders mounted at the bottom surface of the Y table is slidably mounted on the pair of guide rails, respectively. The Y table is formed with an opening at a location between the pair of guide rails, through which a Z shaft assembly extends when mounted on the Y table. Thus, no significant moment is applied to the Y table due to the weight of the Z shaft assembly. Preferably, the Z shaft assembly is so arranged with its center of gravity located below the Y table when mounted thereon so as to provide an increased stability in operation. | ||||||
| 184 | Mobile-structure machine tool for rapid machining of models in particular | US865199 | 1992-04-08 | US5252011A | 1993-10-12 | Armando Corsi |
| This invention relates to a machine tool, designed for rapid machining of models in particular, which comprises a C-shaped structure fitted with a toolhead with several degrees of freedom which can move parallel to one of the machine axes in order to machine non-tough materials rapidly; for example, it can be used to produce plastic models which are to undergo further finishing operations. | ||||||
| 185 | Multi-head type of electro-discharging machine | US555846 | 1990-07-23 | US5075530A | 1991-12-24 | Shih-Lu Lee |
| A multi-head electro-discharging machine, in which each head member has an independent transmission assembly; the head member can move in X-axis, Y-axis and Z-axis directions by a guide screw rod; every head member can be adjusted independently for operation without intervening the others; every head member may be mounted with an electrode connector, and two head members can be operated simultaneously in a crossing manner; a plurality of head members are mounted along the rear side of a supporting frame of the machine, and one or more than one head members may be mounted on both ends of the supporting frame for further multi-processing operation. | ||||||
| 186 | Position seeking apparatus | US516554 | 1990-04-30 | US5072506A | 1991-12-17 | Ernest A. Dacey, Jr. |
| An apparatus for locating a reference target on a partially assembled structure such as an automobile body frame. The apparatus has a base support structure for rigid mounting to a floor member, a transfer platform is attached to the base structure so that the transfer platform has freedom of movement in a first horizontal direction; a horizontal slide assembly is attached to the transfer platform so that it has freedom of movement in a horizontal direction perpendicular to the first horizontal direction; and a vertical slide assembly is attached to the horizontal slide assembly and is movable therewith in a vertical direction. An acutator and a clamp bar are utilized to immobilize the transfer platform, and an actuator and a clamp plate are utilized to immobilize both the horizontal and vertical slide assemblies. A plurality of work tools or tool receiving recesses are attached to the vertical slide assembly so that the tool and recess can move toward and away from the automobile body frame. | ||||||
| 187 | Micropositioning device | US900693 | 1986-08-27 | US4805543A | 1989-02-21 | Philippe M. Schwab; Pierre M. Genequand |
| A micropositioning device having a plurality of degrees of freedom is provided. This device is particularly useful in guiding optic components. The device has N degrees of freedom and comprises two rigid members, namely a reference base and a movable platform. The reference base and the movable platform are connected by N independent chains. Each chain consists of N elastic guide means with a single degree of freedom, arranged in series, and an actuator fixed to the reference base. | ||||||
| 188 | Duplicating router | US059654 | 1987-06-08 | US4787430A | 1988-11-29 | Kouichi Miyamoto |
| A duplicating router of the type in which a cutter unit provided with a motor and a cutter is fed vertically and horizontally with respect to a base. A cutter unit feeding screw rod is installed parallel with guide bars and rotates for operation on a vertical guide frame formed through framing left and right guides fitted movably up and down in elongated guide grooves provided on vertical guide plates fixed on both sides of the base and two parallel guide bars supporting the cutter unit for movement to the left and right, thus forming a screw feeding means. A link handle in a link motion is connected between the base and the left and right guides, thus forming a link feeding means. A template is fixed on upper portions of the vertical guide plates. A duplicating recessed groove is formed in the template in the direction orthogonal to an upper surface of the base. A guide in holder is provided upright from the cutter unit to form a guide pin parallel with the horizontal shaft of the cutter unit and fit in the duplicating recessed groove. A compression spring cushions the guide pin against the recessed groove. | ||||||
| 189 | Combination slot mortising, horizontal boring, router table and overarm router machine | US28244 | 1987-03-20 | US4787127A | 1988-11-29 | Jerrold R. Beall |
| A combination woodworking machine for attachment to an electric plunge router, which may be configured as a horizontal boring and slot mortising machine, an overarm router and a router table. An x-y-z table is mounted on a column supported by feet, and a plunge router with its base removed is mounted in various orientations on the column by sliding it onto steel dowels mounted on the column. An electronic speed control reduces the router speed for boring, and an electronic digital readout provides accurate measurement of horizontal movement of the table. | ||||||
