Provided is an automated pallet changer in machine tool which enable miniaturization and cost reduction. A drive unit in the automatic pallet changer includes a planetary reduction gear. The planetary reduction gear has a first output shaft and a second output shaft in which, by fixing one of the first and second output shaft, the other functions as an output shaft for driving. The first output shaft is used to pivot the pivoting frame, and the second output shaft is used to move the carry-in/out arm back and forth.

A fastening device is equipped with a stocker. The stocker has a circular arcuate shape which is curved in a horizontal plane, and accommodates fastening tools in a state of being aligned in a row. The fastening tool that is positioned at a most downstream side of the stocker is supplied to the receiving site by an unloading and supplying device. Furthermore, the fastening tool supplied to the receiving site is screw-rotated by a screw-rotating device that is displaced toward the fastening tool.

A clamping means system including a bearing device and clamping vices, which fit into the bearing device and respectively have on their base area machine coupling system and on their side faces and flanks a bearing receiving contour and a gripping receiving contour. The bearing receiving contour has the greatest play; the fit between the gripper and the gripper receiving contour is of moderate precision, while the precision of the machine coupling system is the greatest. The clear functional separation between the machine coupling system and the bearing receiving contour or gripper receiving contour allows a reliable low-cost system to be constructed. Furthermore, in the case of mixed partly automated systems, in which parts of the handling tasks are performed by the operator and other parts are performed by gripping robots, the handling is possible in an easy and intuitive way.

The present invention relates to a handling apparatus 1 for use at a machine tool, comprising: a base body 2 which can be set up on a floor space, a storage body 3 which can be set up on the top side of the base body 2 and serves to store a plurality of workpieces or tools, and a handling robot 5, which is arranged on the base body 2 and has a gripper device 6 for receiving a workpiece and/or tool from the storage body 3 and for inserting the workpiece and/or tool taken from the storage body 3 by the gripper device 6 into a corresponding workpiece and/or tool support of the machine tool. A plurality of first set-up elements 18 are arranged on the bottom side of the storage body 3 and a plurality of first centering elements 19 are arranged on the top side of the base body 2, wherein, when the storage body 3 is set up on the top side of the base body 2, the first set-up elements 18 interact in each case in pairs and in self-centering manner with the first centering elements 19 in such a way that the storage body 3 adopts a predetermined reference position in relation to the base body 2.

A feed assembly for a foot-pedal operated riveter and a method of using the same is disclosed. The feed assembly includes a rivet stop that has a tip that separates a lowermost fastener from a second from lowermost fastener when the riveter is in a non-operational position. This rivet stop prevents fasteners from sliding down a raceway on the feed assembly. When the riveter is moved into an operational position, the rivet stop moves out of the way and permits the second from lowermost fastener to slide into position for subsequent installation. The rivet stop thus enables automatic reloading of the riveter during operation.

An intelligent production line for turning tool bit cavities and an application method are provided, which solve the problem that a production line in the prior art has low working efficiency. The intelligent production line has the beneficial effects of a compact arrangement structure, higher safety and improved working efficiency. The intelligent production line for turning tool bit cavities includes a robot. Material tables and at least one machining center are arranged around the robot. A transfer station used for transferring materials is arranged between the machining center and the robot. A protective fence is arranged between a position above the material tables and the robot, and between the transfer station and the robot. The robot is provided with a mechanical arm including a base plate. The base plate is provided with at least one clamping jaw and fixed with a laser detecting unit for detecting the materials.

A rack storage unit for use in an automation system for a storage of work pieces and/or work piece pallets and/or tools, which includes a base frame with a rack stand and two rack side parts arranged at a distance from one another, wherein facing surfaces of the rack side parts are provided with interfaces for mounting placement devices. It is provided that the base frame is produced as a one-piece cast body from artificial stone, and that the interfaces are held by adhesive force as separately formed insert parts in the facing surfaces of the rack side parts.

A device for furnishing screws, in particular on automated screwing systems includes a changing magazine having a plurality of screw holders that each have a closed position for holding in each case one screw in a non-positive manner and an open position for releasing the screw. The screw holder remains in its open position or in its closed position in the absence of a supply of energy A method for furnishing screws, in particular on automated screwing systems, relates to the device.

A manufacturing system includes a base and multiple work machine modules that are attachable and detachable to and from the base arranged in the arrangement direction on the base or on the side of the base, in which the plurality of work machine modules include one or more processing work modules that perform machine processing work on a workpiece using a tool, and one or more supplementary work modules that perform supplementary work that is work supplementarily performed to the machine processing work. Since it is possible to easily increase and decrease the number of processing work modules and supplementary work modules or sort the modules, it is possible to easily recombine the modules with respect to modification of the manufacturing process.
