The invention relates to a method for joining two components (10, 12) of a unit (1), especially a fractured unit, to be screwed together. Said method comprises the following steps: the components are first joined by a joining device (2), especially a joining press (22), the components are separated, and the components are then rejoined by being screwed together.
The invention relates to a method for detecting foreign bodies, especially inclusions, particles and/or impurities, during the assembly of two components (60, 62) to form a unit (6), said method comprising the following steps: the components are joined by applying a joining force, the joining force/course characteristic is recorded during the joining, the joining force/course characteristic is compared with a group of reference characteristics, especially including a range of tolerance, and a step of removing the foreign body and/or emitting a message on detection of a deviation of the joining force/course characteristic, recorded during assembly, from the group of reference characteristics, especially including the range of tolerance, is carried out.
The invention relates to a method for introducing surface structures, in particular surface roughnesses (70), in the contact surface (20) of a component (2), in particular a connecting rod or a universal joint yoke, having a friction fit with a further part (26), in particular a bearing shell, wherein the surface structures are introduced into the contact surface of the component for increasing the friction, wherein the contact surface is impinged at least in segments by a shot carrying an impulse for producing the surface structures.

FRACTURE SEPARATION MODULE FOR A MACHINE TOOL, MACHINE TOOL WITH A FRACTURE SEPARATION MODULE, AND FRACTURE SEPARATION METHOD
Fracture separation module for insertion into a machine tool, comprising: A drive spindle (10) with a receiving section for clamping the module into a spindle of a machine tool, a fracturing part (20) for the fracture separation of a workpiece, a conversion unit (30) which is connected both to the drive spindle (10) and to the fracturing part (20) and converts a rotational movement of the drive spindle (10) into a linear movement of the fracturing part (20), which movement is suitable for fracturing the workpiece, and a method for the fracture separation of a workpiece, wherein the fracture separation step takes place by means of the fracture separation module of the present invention.
The invention relates to a machining device assembly (100; 200; 300) and a method for machining connecting rods (10) for combustion engines. Said machining device assembly (100; 200; 300) comprises modular machining stations (110-116, 180; 210-216; 310-316) for carrying out one or several machining steps on a connecting rod (10) as well as a conveying device (120; 220; 320) for interlinking the machining stations and conveying the connecting rods (10) between the machining stations. The machining stations can be operated separately from the machining device assembly.
