A key duplicating machine, the key duplicating machine for duplicating notches of an original key to a key blank and comprising:
- a base assembly having:
- a base;
- a first direction;
- and
- a second direction opposite to the first direction;
- a first clamp fixed on the base of the base assembly;
- the first clamp used for clamping the original key;
- the notches of the original key extending in the first direction of the base assembly;
- a second clamp fixed on the base of the base assembly, and disposed apart from the first clamp;
- the second clamp used for clamping the key blank;
- a second sliding table slidably mounted on the base, and the second sliding table being movable relative to the base in a direction perpendicular to the first direction and the second direction;
- a second driving mechanism mounted between the base and the second sliding table, and the second driving mechanism driving the second sliding table to move relative to the base;
- the second driving mechanism having:
- a second manual operating part being a lever pivotally mounted on the base;
- a drive slot formed in one end of the lever;
- and
- a dowel pin protruding from a side of the second sliding table;
- the dowel pin extending in the first direction from the side of the sliding table, and slidably mounted in the drive slot;
- wherein a position of the second sliding table relative to the base is determined by a pivoting angle of the lever;
- a first sliding table slidably mounted on the second sliding table, and being movable along the first direction or the second direction relative to the second sliding table;
- the first sliding table is located next to the first clamp and the second clamp;
- a first driving mechanism mounted between the base assembly and the first sliding table;
- the first driving mechanism driving the first sliding table to move along the first direction or the second direction relative to the base assembly;
- and the first driving mechanism having a first manual operating part;
- a cutting module pivotally mounted on the first sliding table, and having:
- a swing table pivotally mounted on the first sliding table;
- a guiding element fixed on the swing table, the guiding element protruding from a side of the swing table facing in the first direction;
- the guiding element corresponding in position to the original key;
- a cutting element rotatably mounted on the swing table, the cutting element protruding from the side of the swing table facing in the first direction;
- a rotational axis of the cutting element extending parallel to each of the first and second directions;
- the cutting element corresponding in position to the key blank;
- and
- a motor fixed on the swing table and driving the cutting element to rotate;
- wherein a center of gravity of the cutting module is located between the second clamp and a pivoting axis of the cutting module, such that the cutting module rotates in a direction in which the guiding element and the cutting element move towards a top surface of the first sliding table, thereby the guiding element selectively abutting against one of the notches of the original key;
- wherein when the guiding element abuts against one of the notches of the original key, the cutting element cuts the key blank.
