In the machine tool 2, two or more machine tables 5 are movably provided on the linear way 4 of the machine base 2, the pinion gear 14 is engaged with the rack 13 of the machine base 3, and the feeding movement of each table 5, the pinion gear 14 is driven by a feed motor 15 mounted on each table 5, and the feed motor 15 is controlled by the table control unit 21 so that the table 5 is fed and moved. In the table independent mode, the movement of the table 5 is independently controlled, and in the table linkage mode, the feeding movements of two or more tables 5 are controlled in the same direction at the same speed and in the synchronous state as the same movement amount.

The present disclosure shows a gantry loader having at least one carriage travelable at a horizontal guide rail, in particular for the transport of workpieces between stations of a production system, wherein the carriage has at least one drive. The present energy is characterized in that the carriage has an energy store for the at least partial energy supply of the drive.

A carrier transmission device comprises a slide rail, a rack and a pair of gears. The slide rail extends along a transmission direction of a carrier to be transmitted and is adapted to slidingly guide the carrier. The rack extends along the transmission direction and is connectable to, or integrally formed on, the carrier. The pair of gears are spaced by a predetermined distance in the transmission direction and are adapted to engage with the rack and drive the carrier to move in the transmission direction on the slide rail.

A positioning system includes a slide support, on which is mounted a positioning slide, which can be driven to perform a positioning movement in a positioning plane with the aid of drive gears of the slide support, wherein the positioning plane is defined by a Cartesian x-y coordinate system. The drive gears are represented by at least one x-drive gear, which can cause a positioning movement in the x-axis direction, and at least one y-drive gear, which can cause a positioning movement in the y-axis direction. The drive gears are in engagement with a driven toothing structure of the positioning slide, which includes a plurality of driven teeth distributed in a punctiform arrangement in a regular two-dimensional tooth matrix. Although the drive gears are short, the positioning system facilitates a traverse of the positioning slide within a large positioning area.

The invention provides a machine tool eliminating the need of keeping the removed feed-mechanism-protection cover outside the machine. The machine tool comprises a headstock provided with a main spindle for gripping a workpiece; a driving unit provided with a feed mechanism extended along a main spindle axis to move the headstock in a main spindle axial direction; a supporting bed provided with a guide bush in a removable manner; a first cover mounted on the headstock to protect a portion of the feed mechanism with respect to the main spindle axial direction; and a second cover removably mounted on the headstock on the front side of the first cover to protect another portion of the feed mechanism. The second cover is detachably attached to the first cover when removed from the headstock.

A positioning unit for a carriage is adjustable by way of a linear drive and a base. The linear drive has an elongate part and a short part. The positioning unit has two compensation rods. In each case two adjacent compensation rods are connected together at one end via a joint and are connected at the other end to the elongate part of the linear drive via one of two joint arrangements that are arranged in each case at the end of the elongate part. The compensation rods and the elongate part of the linear drive are arranged in the form of a triangle and the angle between the compensation rods and the joint is variable by a thermal change in length of the elongate part of the linear drive. The carriage is connected to the joint and the short part of the linear drive is connected to the base.

A drive device for a movement unit of a machine tool includes a first toothed element driven by a drive motor and provided as a drive pinion including a first tooth arrangement and a second toothed element provided as a toothed rack including a second tooth arrangement. One of the first and second toothed elements is connected to a machine frame, and the other of the first and second toothed elements is connected to the movement unit. The first and second toothed elements are moved relative to each other along a movement axis of the first and second toothed elements by the drive motor via a meshing between the first and second tooth arrangements and via an engagement between the first and second tooth arrangements along an engagement axis that extends perpendicularly to the movement axis.

A gantry machine tool includes a pair of vertical uprights joined atop by a transverse beam, on which a tool holder head is slidingly mounted, and a worktable for anchoring a workpiece, above which the tool holder head is movable. Each upright includes a carriage adapted to slide along a longitudinal support structure, which includes a horizontal surface coplanar to the worktable and a lateral surface embedded in the floor and having a guide system for the carriage.

This application relates to a delivery apparatus and an automated assembly line. The delivery apparatus may include: a delivery assembly including a delivery guide rail and a delivery tool, where the delivery tool may be slidably disposed on the delivery guide rail; a docking assembly including a docking drive structure and a docking guide rail, where the docking drive structure may be configured to drive the docking guide rail to move relative to the delivery guide rail so that the docking guide rail is able to dock with the delivery guide rail; and a blocking assembly configured to block the delivery tool on the delivery guide rail before the docking guide rail docks with the delivery guide rail for receiving the delivery tool.
