## Abstract

A work head including a head main body, multiple movable bodies held to be approachable to or separatable from each other by the head main body, and an air passage formed, being open between the multiple movable bodies, in the head main body, in which by gripping a holding tool configured to hold a component by approach of the multiple movable bodies, the holding tool communicates with the air passage and holds the component by supply of air to the holding tool via the air passage.

## Claims

### Claim 1

A work head comprising:
a head main body;
multiple movable bodies held by the head main body and configured to be approachable to and separatable from each other, the movable bodies configured to detachably grip a holding tool configured to mount a tool configured to hold a component;
an air passage formed, being open between the multiple movable bodies, in the head main body; and
wherein the work head grips a flange of the tool, by causing the multiple movable bodies to approach the tool so that the tool is attached to the work head and configured to hold the component.

### Claim 2 (depends on 1)

The work head according to claim 1, wherein the tool is two or more claws and a flange of the two or more claws is gripped by grooves formed on opposing side faces of the movable bodies, the component being gripped by the two or more claws held by the movable bodies.

### Claim 3 (depends on 2)

The work head according to claim 2, wherein a pusher is connected to the air passage via a connecting mechanism in a state in which the two or more claws are fixed to the movable bodies, and the component gripped by the two or more claws is pressed by the pusher by supply of air to via the air passage.

### Claim 4

A work machine comprising:
a work head,
a head main body,
multiple movable bodies held by the head main body and configured to be approachable to and separatable from each other, the movable bodies configured to grip a holding tool configured to mount a tool configured to hold a component, and
an air passage formed, being open between the multiple movable bodies, in the head main body;
a moving device configured to move the work head;
a control device configured to control operation of the moving device; and
an accommodation section configured to accommodate the tool,
wherein the movable bodies include fixing mechanism includes an engaging body configured to move between an engaging position with the tool and a disengaging position from the tool, and is configured to fix the tool by engagement of the engaging body with the tool and separate the tool by disengagement, and
by controlling the operation of the moving device by the control device such that the engaging body abuts on an abutting section formed in the accommodation section in a state in which the tool are fixed to the movable bodies, the engaging body is moved from the engaging position with the tool to the disengaging position from the tool, the tool are separated from the movable bodies, and the tool are accommodated in the accommodation section.

### Claim 5 (depends on 1)

The work head according to claim 1, wherein the tool is a nozzle and a flange of the nozzle is gripped by grooves formed on opposing side faces of the movable bodies, the component being held by the nozzle via air supplied to the nozzle by the air passage.
