Definitions

the invention relates to a device for clamping crankshafts during hardening of the bearing surfaces, consisting of two spaced-apart clamping heads, at least one of which is displaceable for receiving the crankshaft, and a fixed center support.
Such a device is e.g. known from DE-PS 37 37 694.
This hardening device comprises a stationary support with three rollers, also called support roller stands, which supports the crankshaft with one, two or three rollers, mostly in the central region during hardening, in order to reduce the delay in hardness. With three rollers, one roller has to be moved around the bearing of the crankshaft which is supported. Since this is relatively complex, the supports are usually equipped with two rollers that support the crankshaft on a main bearing.
the invention is based on the object of proposing means which, on the one hand, enable a stable, that is to say fixed, attachment of a center support, but on the other hand, through which the supported main bearing surface of the crankshaft can be hardened without hindrance by the support.
the invention proposes in the generic device in that both clamping heads are coupled for common movement with the clamped by them crankshaft. Due to the design according to the invention, the crankshaft can be shifted in its axial position so that the support fixed on the machine bed can be used on several main bearings to support the crankshaft.
crankshaft hardening device In a preferred embodiment of the crankshaft hardening device according to the invention, two separate drives are arranged for the joint movement of the two clamping heads, which drives can be moved with sufficient accuracy within the axial expansion-displacement possibility required for the hardening process in the clamping head by means of suitable electrical coupling.
the two clamping heads are displaceably arranged on a common machine bed, on which a center support is fixed, and are coupled for common displacement by means of a spindle on which the drive engages.
the displacement is preferably carried out with a common spindle which is moved by a single drive.
crankshaft is expediently clamped when the clamping heads are moved to align the crankshaft with the stationary center support. Before moving the clamping heads, the crankshaft should be turned into a favorable position so that when moving, a crank does not hit the stationary support.
crankshaft hardening device thus enables a stable, fixed arrangement of the center support on the machine bed, but on the other hand also a hardening of the main bearing surface supported by the support in the starting position, in that the crankshaft is displaced axially for hardening this main bearing surface by jointly displacing the clamping heads that clamp it.
two clamping heads 1, 2 can be moved on a stationary machine bed M in the axial direction of the crankshaft 3 clamped between them.
Clamping heads 1,2 clamped crankshaft 3 are first rotated about their axis into a favorable position for longitudinal displacement. This is to ensure that when the crankshaft 3 is displaced longitudinally, one of its crank cheeks does not abut the center support 4.
the clamping heads 1, 2 with the crankshaft 3 clamped between them are simultaneously displaced by means of a drive 7, 8 via spindles 9, 10.
the drives 7, 8 are expediently electrically coupled.
FIG. 2 corresponds in principle to that shown in FIG. 1, only the displacement drive is designed differently.
the displacement of the clamping heads 1, 2 with the crankshaft 3 clamped between them in the longitudinal direction of the same takes place together with the machine bed M on a base S with the aid of a single drive 8 'via a spindle 10' acting on the machine bed M.
the clamping head 2 contains a floating quill 12, which permits an axial displacement to compensate for an expansion / shortening occurring during hardening, in order to prevent permanent distortion of the crankshaft hardness.
