Abstract

A placing table includes a measuring-unit that measures a vertical position of an orifice member placed on the placing table, a position-regulating-portion that engages with a part of the orifice member of a type corresponding to the table, and an orifice-member-determination-unit that determines a placed state and type of the orifice member based on a measurement result obtained by the measuring-unit. When the corresponding type of the orifice member is placed in a correct posture, the position-regulating-portion engages with the orifice member and seats the orifice member on the table over the entire circumference of the lower end portion thereof. When a different type of orifice member is placed or when the corresponding type of orifice member is placed in an incorrect posture, the position-regulating-portion does not engage with the orifice member and lifts at least a part of the orifice member from the table.

First claim

What is claimed is:

1. An orifice member placing table on which a first orifice member to be incorporated in a liquid chamber of a liquid-sealed vibration-proof mount is placed, the placing table comprising:
a measuring unit that measures a vertical position of the first orifice member placed on the placing table;
a position regulating portion that engages with a part of the first orifice member; and
an orifice member determination unit that determines a placed state of the first orifice member and a type of the first orifice member based on a measurement result obtained by the measuring unit,
wherein when the first orifice member is placed in a correct posture, the position regulating portion engages with the first orifice member and seats the first orifice member on the placing table over an entire circumference of a lower end portion of the first orifice member, and
when a second orifice member different, at least, in shape from the first orifice member is placed or when the first orifice member is placed in an incorrect posture, the position regulating portion does not engage with the second orifice member or the first orifice member placed in the incorrect posture and lifts at least a part of the second orifice member or the first orifice member placed in the incorrect posture from the placing table.

2. The orifice member placing table according to claim 1 , wherein
the first orifice member includes a through-hole extending through the first orifice member in a thickness direction and a partition wall that partitions the first orifice member in the thickness direction at a position displaced to an opposite side to the placing table relative to a central portion in the thickness direction while the first orifice member is placed on the placing table in a correct posture, and
the position regulating portion includes a positioning pin that engages with the through-hole and a lifting pin that does not interfere with the partition wall when the first orifice member is positioned by the positioning pin and placed in a correct posture, and interferes with the partition wall and lifts the second orifice member or the first orifice member placed in the incorrect posture from the placing table when the second orifice member is placed or the first orifice member is placed in an incorrect posture.

3. The orifice member placing table according to claim 1 , wherein
the first orifice member includes a notch formed in one end portion located on a first side in the thickness direction so as to be notched in a groove shape, with the first side opening to an inside of the first orifice member in a direction orthogonal to the thickness direction, and
the position regulating portion engages with the notch when the first orifice member is placed in a correct posture, and interferes with a second end portion located on the second end side in the thickness direction of the first orifice member and lifts the second orifice member or the first orifice member placed in the incorrect posture from the placing table when the second orifice member is placed or the first orifice member is placed in an incorrect posture.

4. An orifice member placing method comprising:
placing the first orifice member on the orifice member placing table according to claim 1 ;
measuring a height of the first orifice member on the placing table by using the measuring unit; and
determining a placed state of the first orifice member based on a measurement result obtained by the measuring unit.

5. A liquid-sealed vibration-proof mount manufacturing method comprising:
preparing a rubber member in which the liquid chamber is formed and the first orifice member to be incorporated in the liquid chamber;
placing the first orifice member on the placing table by the orifice member placing method defined in claim 4 ; and
holding the placed first orifice member and incorporating the first orifice member in the liquid chamber of the rubber member.
