Abstract
A handling device for servicing a piston with a small end attached to the piston via a piston pin, having a basic frame, a receiving device that is pivotable or tiltable relative to the basic frame for the piston removed from an internal combustion engine, an actuator for pivoting or tilting the receiving device relative to the basic frame, and a locking device via which the receiving device is lockable on the basic frame in different pivot positions or tilting positions.
Claims11
A handling device for servicing a piston having a small end attached to the piston via a piston pin, comprising:
- a basic frame having bearing struts;
- a receiving device that is pivotable or tiltable relative to the basic frame via the bearing struts for the piston removed from an internal combustion engine, the receiving device comprises:
- a base plate, which acts on the bearing struts via pivot arms;
- at least two spindles each having a first end coupled to the base plate and a second end opposite the first end;
- and a clamping bridge coupled to a respective second end of each of the spindles, wherein the piston can be put down on the base plate and axially clamped via the spindles and the clamping bridge between the base plate and the clamping bridge;
- an actuator that pivots or tilts the receiving device relative to the basic frame;
- and a lock configured to lock the receiving device on the basic frame in different pivot positions or tilting positions.
A method for servicing a piston with a small end attached to the piston via a piston pin with a handling device, comprising:
- removing the piston from an internal combustion engine;
- arranging and clamping the piston on a receiving device of a handling device, wherein the receiving device assumes a defined pivot position or a defined tilting position relative to a basic frame, which is locked via a lock;
- unlocking the lock;
- pivoting or tilting the receiving device with an actuator into a service pivot position or a service tilting position defined for a service to be carried out;
- locking the lock in the service pivot position or the service tilting position and performing the respective service,
- coupling at least two spindles to a base plate each having a first end coupled to the base plate and a second end opposite the first end;
- coupling a clamping bridge to the second end of each of the spindles;
- putting the piston down on the base plate;
- and,
- clamping the piston via the at least two spindles and clamping bridge between the base plate and a clamping bridge.
