Abstract

In an installation structure of a magnet plate for installing a magnet plate for a linear motor to a machine mounting part via a joining member, the magnet plate includes a first face, a second face, a first female threaded part at the second face, and an opening at the first face; the machine mounting part includes a second female threaded part having a winding direction opposite to the first female threaded part on a side opposing the magnet plate; the joining member includes a first male threaded part and a second male threaded part; and the magnet plate is installed to the machine mounting part with the first female threaded part being screwed with the first male threaded part, and with the second female threaded part of the machine mounting part being screwed with the second male threaded part.

First claim

What is claimed is:

1 . An installation structure of a magnet plate for installing a magnet plate for a linear motor to a machine mounting part via a joining member,
wherein the magnet plate includes:
a first face on which a magnet is disposed;
a second face which opposes the machine mounting part;
a first female threaded part provided on a side of the second face; and
an opening that is provided on a side of the first face, communicates with the first female threaded part, and into which a tool for rotating the joining member that fits together with the first female threaded part is inserted,
wherein the machine mounting part includes, at a side opposing the magnet plate, a second female threaded part of which winding direction of thread grooves is opposite to the first female threaded part, wherein the joining member includes:
a first male threaded part that is formed at one end thereof and can screw together with the first female threaded part; and
a second male threaded part that is formed at the other end thereof and can screw together with the second female threaded part, and
wherein the magnet plate is installed to the machine mounting part with the first female threaded part being screwed with the first male threaded part of the joining member, and with the second female threaded part of the machine mounting part being screwed with the second male threaded part of the joining member.

2 . The installation structure of the magnet plate according to claim 1 , wherein an outer circumference of the opening is positioned more inwards than an outer circumference of the first female threaded part of the magnet plate, when viewing the machine mounting part from the magnet plate.

3 . The installation structure of the magnet plate according to claim 2 , wherein outer edges of the magnets which are adjacent and sandwiching the opening therebetween are positioned more outwards than the outer circumference of the opening and more inwards than an outer circumference of the first female threaded part of the magnet plate, when viewing the machine mounting part from the magnet plate.

4 . The installation structure of the magnet plate according to claim 1 , wherein, in the joining member, the first male threaded part is a left-hand thread if the second male threaded part is a right-hand thread, and the first male threaded part is a right-hand thread if the second male threaded part is a left-hand thread.
