Abstract
A safety system is provided for a machine tool which has a frame and a tool. The safety system has a clamping device and a motion device. The clamping device is movable by the motion device from a working position, in which the tool is extended and can be used for working, to a safety position, in which the tool is retracted. The motion device has a first magnetic means connected to or arranged on the tool and a second magnetic means connected to or arranged on the frame, such that movement of the tool by the motion device from the working position to the safety position can be triggered and/or at least partially performed by magnetic force.
Claims33
A safety system for a machine tool which has a frame and a tool, the safety system comprising:
- a clamping device for clamping or mounting the tool in or to the machine tool;
- and
- a motion device,
- wherein:
- the clamping device is moveably arranged on the frame of the machine tool;
- the motion device is configured to move the clamping device from a working position in which the tool is extended and can be used for working to a safety position in which the tool is retracted;
- the motion device includes a first magnetic means and a second magnetic means;
- the first magnetic means is connected to the clamping device;
- the second magnetic means is arranged on the frame of the machine tool;
- the motion device is configured to move the tool from the working position to the safety position at least partially by a magnetic force acting between the first magnetic means and the second magnetic means;
- the first magnetic means and the second magnetic means are arranged in a mutually coaxially opposite relationship;
- and
- the first magnetic means and the second magnetic means are in direct contact with each other when the tool is in the working position.

- the first magnetic means is connected to the clamping device;
- the second magnetic means is arranged on the frame of the machine tool;
- the motion device is configured to move the tool from the working position to the safety position at least partially by a magnetic force acting between the first magnetic means and the second magnetic means;
- the holding device is configured to hold the tool in the working position by a holding force;
- the motion device is configured to apply the holding force at least partially by at least one of the first magnetic means or the second magnetic means;
- and
- the first magnetic means and the second magnetic means are in direct contact with each other when the tool is in the working position.
