Lateral processing machine and tool changer

A tool changer for exchanging a tool with a spindle positioned at tool changing position, the tool changer comprising:

• a magazine disk rotatably supported;
• a cam having a disk-shaped plate, the cam having a contour recessed by a stroke length at the tool changing position;
• a plurality of tool holding portions disposed on an outer periphery of the magazine disk, the tool holding portions each includes,
• a pinch lever swingably supported by the magazine disk, the pinch lever including,
• a claw portion disposed at a distal end of the pinch lever to hold the tool, and
• a lever portion having a roller cam, the lever portion disposed at a basal end of the pinch lever,
• a first elastic member configured to bias the lever portion so as to separate each other,
• a cylinder having a cylinder chamber, the cylinder disposed on the magazine disk,
• a plunger configured to reciprocate in the cylinder chamber, the plunger including,
• a V-plane disposed at a distal end of the plunger to contact the roller cam, and
• a cam follower disposed at a basal end of the plunger, and
• a second elastic member configured to bias the plunger toward the distal end for the V-plane to be pressed against the roller cam to close the pinch lever,
• when the tool holding portion is positioned other than the tool changing positions, the cam follower is in contact with the cam to close the pinch lever, and
• when the tool holding portion is positioned at the tool changing positions, the plunger retracts by the stroke length to open the pinch lever for the tool to be exchanged with the spindle.
