Abstract
A workpiece holding apparatus includes: a main body; at least one shaft member capable of coming into contact with a workpiece; a clamping device into which the shaft member is inserted, the clamping device being attached to the main body and capable of switching between an unclamping state that releases the shaft member and a clamping state that clamps the shaft member; and a trigger member configured to switch the clamping device between the unclamping state and the clamping state. The trigger member comes into direct contact with the workpiece, or comes into indirect contact with the workpiece via at least a part of the shaft member, thus moving relative to the main body, and the clamping device switches from the unclamping state to the clamping state.
Claims20
A workpiece holding apparatus comprising:
- a main body;
- at least one shaft member capable of coming into contact with a workpiece;
- a clamping device into which the shaft member is inserted, the clamping device being attached to the main body and capable of switching between an unclamping state that releases the shaft member and a clamping state that clamps the shaft member;
- and
- a trigger member configured to switch the clamping device between the unclamping state and the clamping state, wherein
- the main body includes a pair of the main bodies placed in such a manner as to sandwich the workpiece,
- each of the pair of the main bodies includes a stationary plate and a movable plate, and
- the trigger member comes into direct contact with the workpiece, or comes into indirect contact with the workpiece via at least a part of the shaft member, thus moving relative to the main body, the movable plate moving relative to the stationary plate, and the clamping device switches from the unclamping state to the clamping state.
A workpiece holding apparatus comprising:
- a main body;
- at least one shaft member capable of coming into contact with a workpiece;
- a clamping device into which the shaft member is inserted, the clamping device being attached to the main body and capable of switching between an unclamping state that releases the shaft member and a clamping state that clamps the shaft member;
- and
- a trigger member configured to switch the clamping device between the unclamping state and the clamping state, wherein
- the trigger member comes into direct contact with the workpiece, or comes into indirect contact with the workpiece via at least a part of the shaft member, thus moving relative to the main body, and the clamping device switches from the unclamping state to the clamping state, and
- the trigger member includes a plate portion through which the at least one shaft member is inserted and with which a contactor at a distal end of the shaft member is capable of coming into contact.
A workpiece holding apparatus comprising:
- a main body;
- a plurality of shaft members capable of coming into contact with a workpiece;
- and
- a plurality of clamping devices into which the plurality of shaft members is inserted, the plurality of clamping devices being attached to the main body and capable of switching between an unclamping state that releases the shaft members and a clamping state that clamps the shaft members, wherein
- as viewed in an axial direction of the main body, the plurality of shaft members includes first shaft members placed at the vertices of a first regular n-gon, and second shaft members placed at the vertices of a second regular n-gon having longer sides than the first regular n-gon, the second regular n-gon having a center substantially the same as that of the first n-gon, the second regular n-gon being rotationally displaced, substantially 180°/relative to the first regular n-gon,
- where n is any of integers equal to or greater than four.
A workpiece holding apparatus comprising:
- a main body;
- at least one shaft member capable of coming into contact with a workpiece;
- a clamping device into which the shaft member is inserted, the clamping device being attached to the main body and capable of switching between an unclamping state that releases the shaft member and a clamping state that clamps the shaft member;
- and
- a trigger member configured to switch the clamping device between the unclamping state and the clamping state, wherein
- the trigger member comes into direct contact with the workpiece, or comes into indirect contact with the workpiece via at least a part of the shaft member, thus moving relative to the main body, and the clamping device switches from the unclamping state to the clamping state, and
- the shaft members are formed hollow, and each include, at a distal end thereof, a suction member that suctions the workpiece.
