Abstract
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.
Claims10
A method for joining two components (10, 12) of a unit (1), especially a fractured unit, to be screwed together, comprising the steps:
- first joining of the components by means of a joining device (2), especially a joining press (22);
- separating the components;
- and
- re-joining the components by screwing them together.
The method according to any of the preceding claims, after separating the components the joining surface, in particular the separation surface., being cleansed of foreign bodies, in particular of particles, inclusions or other impurities, in particular by shaking, brushing, fluid treatment, blowing off, manual removal or other appropriate steps.
The method according to any of the preceding claims, the joining force or the surface pressure being varied during joining in the joining device, in particular in order to accelerate fixing procedures in the joining surface.
The method according to any of the preceding claims, the components being the top (10) and the shaft (12) of a broken connecting rod (1) or the top and the lower part of a universal joint yoke.
The method according to any of the preceding claims, wherein during joining with the joining device, a joining force/path characteristic curve being recorded, the characteristic curve being compared to a family of reference characteristics, and the presence of a foreign body on the separation surface being specified if the joining force/path characteristic curve measured deviates from the family of reference characteristics.
A joining system for implementing according any e preceding claims, comprising
- a joining device (2) for applying a joining force or a surface pressure to the joining surface between the two components of the unit;
- a separating device for separating the two components;
- and
- a screwing device for screwing the two components together.
