摘要： The invention relates to a moving system (100) for moving workpieces that are provided for gear cutting on a workpiece spindle (200) and have a workpiece axis of rotation, from a first position (A), taken up while they are being fed, into a third position (C) that differs from the first position by at least a smaller distance between the workpiece axis of rotation and the workpiece spindle axis, having a first movement unit (36, 32, 34) which moves a workpiece from the first position into a second position (B), different from the first and the third position, along a first movement path (AB), and a second movement unit (35) which moves the workpiece from the second position into the third position along a second movement path (BC), wherein the moving system is also designed to move machined workpieces back out of the third position and to hold and move more than one workpiece at the same time, wherein, while it is being moved on the first and on the second movement path, the workpiece is held by one and the same holding unit (10, 10′) that directly holds the workpiece, without a movement caused by the second movement unit entailing a movement of the first movement unit.

摘要： The invention concerns a method of machining a workpiece, wherein an end-facing tooth edge of a gear profile of the workpiece that was generated by a chip-removing machining process is reworked at a first location into a chamfered edge by way of a plastic forming operation. The material which in the plastic forming operation was displaced towards the end surface of the gear profile is pushed outward as a material protrusion in the end surface of the tooth, while the material displaced towards the flank of the tooth is pushed outward as a material protrusion on the flank side of the chamfer, and the resulting material protrusions in the end surface and on the flank side are removed. The workpiece, while still carrying the material protrusion on the end surface of the gear profile, is transferred to a second location where the protrusion on the flank side of the chamfer is removed.

摘要： To produce toothed sections on workpieces, a machine tool has a machine bed, a pivoting element with at least two workpiece spindles arranged thereon and a tool positioning unit with a tool head. The spindles can be pivoted relative to the machine bed about a workpiece spindle pivot axis and each spindle has a workpiece receiver that can be rotatably driven about a rotational axis. The tool head can be linearly moved in three directions relative to the spindles, and can be pivoted about a tool head pivot axis. A bearing element extending in the direction of the workpiece spindle pivot axis, has a free end which is pivotable about the workpiece spindle pivot axis, and is rigidly arranged on the pivoting element. A reinforcing element is fastened to the machine bed. The pivoting element is reinforced about the workpiece spindle pivot axis by the reinforcing element.

摘要： In a composite-machining machine tool for carrying out a turning operation and a machining center operation, a B-axis shaft 13, having a tool spindle head 14 mounted on its front end, is rotatably supported by a Y-axis slide 10, and the B-axis shaft 13 can be indexingly rotated by a B-axis servomotor 22. Clamp pistons 26 are provided in opposed relation to a flange portion 25 of a front end portion 13A of the B-axis shaft, and the clamp pistons 26 are pressed against the flange portion 25 to thereby fix the B-axis shaft at an arbitrary rotational angle position. By doing so, a hobbing tool 29 can be fixed in such a manner that the axis of this hobbing tool can be precisely indexed at a desired angular position with respect to a workpiece W, thereby enabling a hobbing operation.

摘要： A loader (10) for a gear burnishing machine includes a gear carrier (144) and a guide embodied by a rack (122) for cooperating to move a gear to be burnished into meshing relationship with a gear rack of the burnishing machine. A hopper (22) including a feed mechanism provides feeding of the gears to the carrier. Carrier movement moves the gears from the hopper to the machine as the guide rack aligns the gear teeth for meshing with the gear rack teeth. A retaining shaft of the carrier captures the gears between spaced retainers of the carrier as the gears move to the machine for burnishing. A retaining member (66) and a movable dog (84) of the feed mechanism cooperate in feeding gears to the carrier. After burnishing, an actuator including a pusher (204) moves the burnished gear off the guide to a delivery unit 14 including an inclined ramp (198).

摘要： Apparatus and a method for burnishing gears incorporating a pair of gear racks having opposed forming faces with teeth spaced therealong for meshing with a toothed gear received therebetween to provide the sole support for the gear as it is rotated by rack movement while the rack teeth burnish the gear teeth. A loader is positioned on one lateral side of the gear racks and includes a movable gripper mechanism that positions the gears to be burnished between the racks for meshing engagement therewith as the racks are driven by a reciprocal drive mechanism of the apparatus. Grippers of the gripper mechanism grip the gears during loading and have pushers that push the burnished gears to a delivery guide on the opposite lateral side of the gear racks from the loader. A movable guide member of the guide is fixed to one of the gear racks and receives the burnished gears to feed the gears to a stationary guide member as a pusher fixed to the other gear rack moves the burnished gears during reciprocal driving of the gear racks. A conveyor for feeding the loader includes gear carriers supported by a continuous chain trained over a pair of spaced sprockets. One of the sprockets is adjustably supported by a chain tensioner while the other sprocket is driven by a cylinder and indexing arm through a one-way clutch in order to move the chain and the gears carried by the carriers on the chain.

摘要： A bottom-loading pot broaching machine has a pot broach vertically mounted on a horizontal face of a base support structure to symmetrically distribute loading forces to the machine. This structure also enables loading and unloading arms to be mounted to the pot broach so as to be mechanically coupled and phased to allow both loading and unloading of the pot broach during a single cycle. A magnetic escapement mechanism is mounted proximately to the unloading arm to magnetically retain a finished workpiece for unloading by the unloading arm.
