Abstract

The mounting tool includes a cylindrical bush inserted into a through hole drilled in the scale housing case, an O-ring interposed between an inside wall of the through hole and the bush, a mounting screw inserted into a cylindrical hole of the bush and screwed into a mounting face, and a plate spring arranged between a head part of the mounting screw and an outside face of the scale housing case, and biasing the scale housing case toward the mounting face.

First claim

The invention claimed is:

1. A mounting tool, for a linear displacement measuring apparatus, which mounts the linear displacement measuring apparatus on a mounting face, the mounting tool comprising:
a bush inserted into a through hole drilled in a scale housing case;
an elastic body provided between the through hole and the bush;
a mounting screw inserted into the bush and screwed into the mounting face; and
biasing means arranged between a head part of the mounting screw and the scale housing case, and biasing the scale housing case toward the mounting face, wherein
the bush has a flange part projecting in a direction perpendicular to a shaft, and
the biasing means is rubber thermally welded to a back face of the flange part.

2. The mounting tool for the linear displacement measuring apparatus according to claim 1 , wherein the flange part has a shape which is long in a length measurement direction and short in a direction perpendicular to the length measurement direction.

3. The mounting tool for the linear displacement measuring apparatus according to claim 1 , further comprising a stop ring fit onto the bush and preventing the bush from coming off from the through hole.

4. The mounting tool for the linear displacement measuring apparatus according to claim 1 , wherein the linear displacement measuring apparatus comprises:
a scale housing case having a through hole;
a bush inserted into the through hole;
an elastic body between the through hole and the bush; and
a stop ring fit onto the bush and preventing the bush from coming off from the through hole.

5. A method for mounting the linear displacement measuring apparatus with the mounting tool according to claim 4 , the method comprising:
inserting a mounting screw into the bush; and
screwing the mounting screw into the mounting face.

6. The mounting tool for the linear displacement measuring apparatus according to claim 1 , wherein the elastic body is rubber thermally welded to the bush.

7. A mounting tool, for a linear displacement measuring apparatus, which mounts the linear displacement measuring apparatus on a mounting face, the mounting tool comprising:
a bush inserted into a through hole drilled in a scale housing case;
an elastic body provided between the through hole and the bush;
a mounting screw inserted into the bush and screwed into the mounting face; and
biasing means arranged between a head part of the mounting screw and the scale housing case, and biasing the scale housing case toward the mounting face, wherein
the bush has a flange part projecting in a direction perpendicular to a shaft,
the biasing means is a plate spring, and has a hole for inserting the mounting screw into a stand part which is a center part, and a leg part formed by being bended at an end of the stand part, and
the leg part biases the scale housing case toward the mounting face while the stand part of the plate spring is being sandwiched between the flange part and the head part of the mounting screw.

8. The mounting tool for the linear displacement measuring apparatus according to claim 7 , wherein a gap exists between the flange part and the scale housing case.

9. The mounting tool for the linear displacement measuring apparatus according to claim 7 , wherein the elastic body is rubber thermally welded to the bush.

10. The mounting tool for the linear displacement measuring apparatus according to claim 7 , further comprising a stop ring fit onto the bush and preventing the bush from coming off from the through hole.

11. The mounting tool for the linear displacement measuring apparatus according to claim 7 , wherein the linear displacement measuring apparatus comprises:
a scale housing case having a through hole;
a bush inserted into the through hole;
an elastic body between the through hole and the bush; and
a stop ring fit onto the bush and preventing the bush from coming off from the through hole.

12. A method for mounting the linear displacement measuring apparatus with the mounting tool according to claim 11 , the method comprising:
inserting a mounting screw into the bush; and
screwing the mounting screw into the mounting face.
