Abstract
A tool change unit includes a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base. Each arm body includes a position-returning element, a gripping element, and an actuation element. The position-returning element enables the tool arm to rotate for upward and downward moving between a first position and a second position. The gripping element functions to grip a main-axle tool or a magazine tool. The tool change unit is combinable with a power unit to form a tool change device. The power unit drives the tool change unit to do rotation or rotation and upward and downward movement.
Claims19
A tool change unit, at least comprising:
- a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base, the base comprising a coupling section adapted to couple to a power unit, each of the tool arms comprising an arm body, a position-returning element, a gripping element, and an actuation element;
- wherein the arm body has one end forming a pivoting end coupled to the base and an opposite end forming a gripping end that is mounted with a gripping element;
- the position-returning element is arranged and connected between the arm body and the base, so that by means of the arrangement of the position-returning element, the arm body is rotatable for moving upwards and downwards between a first position and a second position;
- the gripping element is formed with an opening for gripping and holding a tool bar;
- the actuation element is mounted on the arm body and is adapted to be driven by a main axle to cause the arm body to rotate for downward moving.
A tool change device, at least comprising a tool change unit and a power unit, wherein the tool change unit at least comprises:
- a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base, the base comprising a coupling section coupled to the power unit, each of the tool arms comprising an arm body, a position-returning element, a gripping element, and an actuation element;
- wherein the arm body has one end forming a pivoting end couple to the base and an opposite end forming a gripping end that is mounted with a gripping element;
- the position-returning element is arranged and connected between the arm body and the base, so that by means of the arrangement of the position-returning element, the arm body is rotatable for moving upwards and downwards between a first position and a second position;
- the gripping element is formed with an opening for gripping and holding a tool bar;
- the actuation element is mounted on the ann body and is adapted to be driven by a main axle to cause the arm body to rotate for downward moving;
- the power unit at least comprises a rotational axle that is drivable to rotate, the tool change unit being coupled to the rotational axle.
