Key processing machine

A key processing machine, comprising:

• an automatic cutter change device;
• a key bitting code learning device;
• a clamp component;
• and
• a base;
• wherein the automatic cutter change device comprises:
• a frame structure;
• a series of learning cutter heads;
• a processing cutter head;
• a rotary turret;
• and
• a first motor unit;
• wherein the rotary turret comprises a plurality of head receiving chambers;
• wherein the series of learning cutter heads and the processing cutter head are each installed in a respective one of the plurality of head receiving chambers;
• wherein the rotary turret and the first motor unit are installed on the frame structure;
• wherein the first motor unit drives the rotary turret to rotate and further drives the processing cutter head to rotate with respect to the rotary turret;
• wherein the key bitting code learning device comprises:
• a processing cutter disc;
• a cutter disc measuring head having a contact part;
• and
• a first drive;
• wherein one end of the cutter disc measuring head is used to bring the contact part thereof into contact with an original key that is to be duplicated;
• wherein the first drive drives the cutter disc measuring head to move and further drives the contact part to make contact with or move away from the original key;
• wherein the clamp component comprises:
• a second motor unit and a fixing device;
• wherein the fixing device is used to hold in place each of the original key and a key blank that is to be cut in accordance with tooth shape data of the original key;
• wherein the second motor unit drives the fixing device to move in a horizontal plane;
• wherein the base is fitted with the automatic cutter change device,
• wherein the automatic cutter change device and the key bitting code learning device are arranged on opposing sides of the clamp component;
• wherein the automatic cutter change device or the key bitting code learning device will learn the tooth shape data of the original key positioned on the clamp component and will cut the key blank that is positioned on the clamp component;
• and
• the automatic cutter change device learns the tooth shape data of the original key via the series of learning cutter heads, whereas the key bitting code learning device learns the tooth shape data of the original key via the contact part.
