Abstract
The present invention relates to a cutting device for use in cutting a collar which is mounted on a bolt in half, the cutting device comprising: ⋅ a mouth (16) for receiving the portion of the collar (28) to be cut; ⋅ a pair of jaws (17a, 17b) diametrically opposite one another and located within the mouth (16), each jaw (17a, 17b) being provided with a cutting blade (18), ⋅ a driver (22) for moving at least one jaw (17a) relative to the other (17b) such that the collar (28) can be cut in half by the action of the jaws (17a, 17b) moving towards one another, and ⋅ a guard (15) which, in use, prevents the cutting blade (18) from protruding beyond the mouth (16) and damaging a surface adjacent to the collar (28) to be cut in half.
Claims21
A cutting device for use in cutting a collar which is mounted on a bolt in half, the cutting device comprising:
- a mouth for receiving the portion of the collar to be cut;
- a pair of jaws diametrically opposite one another and defining a plane of the pair of jaws, and located within the mouth,
- each jaw being provided with a cutting blade, wherein the cutting blade lies in a cutting blade plane which is offset from the plane of the jaws;
- a driver for moving at least one jaw relative to the other such that the collar can be cut in half by the action of the jaws moving towards one another and including a stop member;
- and
- a guard which, in use, prevents the cutting blade from protruding beyond the mouth and damaging a surface adjacent to the collar to be cut in half.
A method for cutting a collar attached to a bolt located on a body of an aircraft, the method involving the use of a cutting device by engaging a cutting blade of each jaw with the collar, wherein the cutting device comprises:
- a mouth for receiving the portion of the collar to be cut;
- a pair of jaws diametrically opposite one another and located within the mouth,
- each jaw being provided with the cutting blade,
- a driver for moving at least one jaw relative to the other such that the collar can be cut in half by the action of the jaws moving towards one another, and
- a guard which, in use, prevents the cutting blade from protruding beyond the mouth and damaging a surface adjacent to the collar to be cut in half.
A blade for use with a cutting device, wherein a blade is triangular or substantially triangular in cross section, and wherein the cutting device comprises:
- a mouth for receiving the portion of the collar to be cut;
- a pair of jaws diametrically opposite one another and located within the mouth,
- each jaw being provided with the cutting blade,
- a driver for moving at least one jaw relative to the other such that the collar can be cut in half by the action of the jaws moving towards one another, and
- a guard which, in use, prevents the cutting blade from protruding beyond the mouth and damaging a surface adjacent to the collar to be cut in half.
