Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a mounting structure for a position detecting sensor, and particularly to a mounting groove formed in a detected device such as a cylinder device when the detected device is mounted. The present invention relates to a technique effective when applied to a mounting structure of a position detecting sensor that can be mounted in a direction perpendicular to, and is capable of highly reliable position detection.

[Prior Art] For example, as a mounting structure for a position detecting sensor, a mounting groove having an inverted T-shaped cross section is formed along the axial direction of the outer peripheral portion of a device to be detected such as a cylinder device. Similarly, it is formed in an inverted T-shaped cross section so as to be fitted in this mounting groove.

Then, the position detecting sensor is inserted into the mounting groove of the cylinder device from the axial direction of the one end side, and is tightened by the set screw at a predetermined detection position so that the position detecting sensor is attached by the pressing force of the set screw. ing.

[Problems to be Solved by the Invention] However, in the above-described conventional technique, since the cylinder device and the position detection sensor are formed in a cross-sectional shape that fits with each other, the position detection sensor is attached to the cylinder device. In the case of mounting, there is a drawback that the mounting is limited to the axial insertion into the mounting groove of the cylinder device, and the mounting cannot be performed from the outer side of the cylinder device, that is, the direction perpendicular to the mounting groove.

Therefore, when installing the cylinder device to which the position detection sensor is fixed to another device, provide a space longer than the length of the position detection sensor in the axial direction of at least one end side of the cylinder device, or before installing the cylinder device. In addition, there is a problem that the position detecting sensor must be inserted into the mounting groove of the cylinder device and then the cylinder device must be mounted to another device. Furthermore, in the latter case, there is a problem that the position detection sensor must be removed after removing the cylinder device from the other device when removing the position detection sensor.

In addition, in the conventional position detection sensor, since the sensor body is attached by tightening it with the set screw, the sensor body is deformed by the pressing force of the set screw, and the position detection circuit housed inside is affected at the same time. However, there is a problem that sufficient detection accuracy cannot be ensured and the reliability of the detection position cannot be obtained.

Therefore, an object of the present invention is to make it possible to easily attach and detach from a mounting groove of a detected device such as a cylinder device in a direction perpendicular to the mounting groove, and at the same time, to perform position detection with high reliability. It is to provide a mounting structure for a detection sensor.

The above and other objects and novel features of the present invention are as follows.
It will be apparent from the description of this specification and the accompanying drawings.

[Means for Solving the Problems] Among the inventions disclosed in the present application, the outline of a typical one will be briefly described as follows.

That is, the mounting structure of the position detecting sensor of the present invention is
A mounting structure for a position detecting sensor, wherein the position detecting sensor is fitted into a mounting groove formed in a device to be detected and is mounted by being pressed by a fastening member, wherein the position detecting sensor is a sensor body. And a fastening member which is composed of an attachment portion coupled to the sensor body portion, the attachment portion being rotatably fixed to one end side of the sensor body portion,
A member to be fastened which is screwed to the fastening member and rotated by a predetermined angle, and the fastening member is turned and the member to be fastened is displaced by being screwed to the position detecting sensor. A pressing force acts between the detection target device and the detection target device, and the position detection sensor is mounted in the mounting groove of the detection target device by the pressing force.

The mounting portion includes a fastening member that is rotatably fixed to one end of the sensor body, and a fastened member that is screwed into the fastening member and is turned by a predetermined angle. The mounting groove of the device to be detected is formed in a substantially cross-shaped or substantially inverted T-shaped cross section having a recess in a direction perpendicular to the mounting groove, and the position detecting sensor is inserted into the mounting groove from the perpendicular direction. It is designed to be attached.

Further, the fastened member is formed into a substantially rectangular shape having different vertical and horizontal dimension ratios, and is rotated by a predetermined angle so that the short side of the fastened member is locked in the recess of the mounting groove. It was made possible.

[Operation] According to the above-described mounting structure for the position detecting sensor, the position detecting sensor is composed of the sensor main body and the mounting portion coupled to the sensor main body, and this mounting portion is on one end side of the sensor main body. By providing a fastening member that is rotatably fixed to the fastening member and a fastened member that is screwed to the fastened member and is turned by a predetermined angle, the fastening member is turned and the fastened member is screwed. By being displaced, a pressing force acts between the position detecting sensor and the device to be detected, and the pressing force allows the position detecting sensor to be attached to the mounting groove of the device to be detected.

In this case, the mounting groove of the device to be detected is formed in a substantially cross-shaped or a substantially inverted T-shaped cross section having a recess in a direction perpendicular to the mounting groove, and the fastened member has a substantially vertical and horizontal dimension ratio different from each other. Since the position detecting sensor is formed in a rectangular shape and the position detecting sensor is inserted into the mounting groove from the direction perpendicular to the mounting groove, the position detecting sensor can be easily mounted from the direction perpendicular to the mounting groove of the device to be detected. The position detection sensor can be easily removed in the direction perpendicular to the mounting groove as in the case of mounting.

Further, the position detecting sensor includes a sensor main body, a fastening member that is rotatably fixed to one end of the sensor main body, and a fastened member that is screwed to the fastening member and is turned by a predetermined angle. Since the pressing force of the fastening member of the mounting portion is not influenced by the sensor main body, the position detecting sensor can be prevented from being deformed.
