Abstract
An object of the present invention is to provide a chamber in which workpieces of different sizes can be positioned. A chamber according to an aspect of the present invention is a chamber for a leak tester, the chamber housing in the interior thereof a workpiece having an opening, the chamber including: a first member having a recess that forms a housing space for the workpiece; a second member adapted to close an open end of the recess; and a positioning mechanism for positioning the workpiece within the housing space such that the opening is in a predetermined position, wherein the positioning mechanism holds the workpiece apart from the first member and the second member.
Claims14
A chamber for a leak tester, the chamber housing in an interior thereof a workpiece having an opening, the chamber comprising:
- a first member having a recess that forms a housing space for the workpiece;
- a second member adapted to close an open end of the recess;
- and
- a positioning mechanism for positioning the workpiece within the housing space such that the opening is in a predetermined position,
- wherein the positioning mechanism includes a spacer plate and a pushing body,
- wherein the pushing body is disposed so as to face the spacer plate with the workpiece therebetween,
- wherein the pushing body is adapted to push the workpiece toward the spacer plate, and
- wherein the positioning mechanism holds the workpiece apart from the first member and the second member.
A chamber for a leak tester, the chamber housing in an interior thereof a workpiece having an opening, the chamber comprising:
- a first member having a recess that forms a housing space for the workpiece;
- a second member adapted to close an open end of the recess;
- and
- a positioning mechanism for positioning the workpiece within the housing space such that the opening is in a predetermined position,
- wherein the positioning mechanism includes:
- a first moving body that projects into the housing space and supports the workpiece in a predetermined position in a projection direction of the first moving body;
- and
- a second moving body that projects into the housing space such that the second moving body faces the first moving body, and pushes the workpiece toward the first moving body, and
- wherein the positioning mechanism holds the workpiece apart from the first member and the second member.
A lid for use on a chamber for a leak tester, the chamber housing a workpiece having an opening, the lid comprising:
- a lid body that is adapted to close an entrance or exit through which the workpiece is inserted into or removed from the chamber;
- a spacer plate disposed on an inner surface side of the lid body such that an interval is formed between the spacer plate and the lid body;
- and
- a pushing body disposed on the inner surface of the lid body such that the workpiece is sandwiched between the pushing body and the spacer plate,
- wherein the pushing body is disposed so as to face the spacer plate with the workpiece therebetween, and
- wherein the pushing body is adapted to push the workpiece toward the spacer plate.
A leak tester comprising a chamber, the chamber housing in an interior thereof a workpiece having an opening, the chamber comprising:
- a first member having a recess that forms a housing space for the workpiece;
- a second member adapted to close an open end of the recess;
- and
- a positioning mechanism for positioning the workpiece within the housing space such that the opening is in a predetermined position,
- wherein the positioning mechanism includes a spacer plate and a pushing body,
- wherein the pushing body is disposed so as to face the spacer plate with the workpiece therebetween,
- wherein the pushing body is adapted to push the workpiece toward the spacer plate, and
- wherein the positioning mechanism holds the workpiece apart from the first member and the second member.
