Claims

[Scope of utility model registration request]

Multiple interchangeable heads are mounted around an indexing table that can be rotated forward and backward around the main shaft fixed on the machine base, and any interchangeable head is indexed directly under the power unit in front and used in conjunction. In interchangeable head multi-axis machine tools, the power unit is equipped with two or more positioning pins that move up and down using hydraulic or pneumatic pressure, and the lower ends of these positioning pins fit into the positioning holes provided on the top surface of the interchangeable head to ensure accurate positioning. In addition to enabling positioning, this positioning pin and the power unit output shaft are connected by a connecting arm, and at the same time as the positioning pin is positioned, the power unit output shaft also lowers in conjunction, and its lower end connects to the upper end of the exchangeable head input shaft. A power unit for a head exchangeable multi-axis machine tool, characterized in that the clutch is engaged with the locating pin and then clamped, and furthermore, the vertical movement of the positioning pin is detected and the connection is confirmed by means of an indicator lamp, etc. Interchangeable head articulation device.
