Abstract

[Purpose of the article]; This article is a sensor installation device used to install the sensor that detects the position of the piston that reciprocates along the axial direction inside the cylinder tube on the outer peripheral surface of the cylinder tube of the fluid pressure cylinder. ; When in use, first, as shown in the reference perspective view showing the use state, the sensor holder is placed at a desired position on the outer peripheral surface of the cylinder tube of the fluid pressure cylinder. The other end of the belt is wound along the outer circumferential surface of the cylinder tube, and the T-shaped reinforcing plate on the other end of the belt is inserted into the engagement hole of the sensor holder. When the fastening screw is tightened and the distance between the outer peripheral surface of the cylinder tube and the belt portion is increased, tension is applied to the belt portion and the sensor holder is fixed to the cylinder tube. When the sensor is inserted into the sensor holder in this state, the T-shaped reinforcing plate provided on the front of the belt portion will be in contact with or close to the outer peripheral surface of the sensor. Therefore, even if the T-shaped reinforcing plate is to be removed from the sensor holder, the T-shaped reinforcing plate will collide with the outer peripheral surface of the sensor, preventing the belt portion from being removed. ;[Design Description];This design is a derivative design of patent application No. 106302526. ;The sensor installation device of this design article has: a track-shaped sensor holder to hold the sensor; a belt-shaped belt part connected to the lower part of the sensor holder and wound around the cylinder tube The outer peripheral surface; the fastening screws are used to fasten the belt part and fix the sensor holder to the cylinder tube (refer to the reference perspective view showing the names of each part). ; The sensor holder system has: a rectangular bottom wall; and side wall portions erected from the long sides on both sides of the bottom wall and facing each other.

Description

Sensor mounting

This article is a sensor mounting device for mounting a sensor for detecting the position of a piston reciprocating in the axial direction inside the cylinder tube to the outer circumferential surface of the cylinder tube of the fluid pressure cylinder.

In use, first, as shown in the reference perspective view showing the state of use, the sensor holder is placed at a desired position in the outer peripheral surface of the cylinder tube of the fluid pressure cylinder. The other end side of the belt portion is wound along the outer peripheral surface of the cylinder tube, and the T-shaped reinforcing plate on the other end side of the belt portion is inserted into the engaging hole of the sensor holder. When the fastening screw is tightened and the distance between the outer circumferential surface of the cylinder tube and the belt portion is increased, tension is applied to the belt portion to fix the sensor holder to the cylinder tube. When the sensor is inserted into the sensor holder in this state, the T-shaped reinforcing plate provided on the belt portion abuts or approaches the outer peripheral surface of the sensor. Therefore, even if the T-shaped reinforcing plate is to be detached from the sensor holder, the T-shaped reinforcing plate collides with the outer peripheral surface of the sensor to prevent the belt portion from being removed.

This design is related to the derivative design of the patent application No. 106302526.

The sensor mounting device of the design article has a track-shaped sensor holder that holds the sensor, and a belt-like belt portion that is coupled to the lower portion of the sensor holder and wound around the cylinder tube. The outer peripheral surface; a fastening screw for fastening the belt portion to fix the sensor holder to the cylinder tube (refer to the reference perspective view showing the names of the respective parts).

The sensor holder has a rectangular bottom wall portion and side wall portions that are erected from the long sides of both sides of the bottom wall portion and face each other. A cut portion that is cut from the upper end of the side wall portion to the lower end is provided at the center of one of the side wall portions, and a curved claw portion is protruded outward in the short side direction of the bottom wall portion in the lower portion of the cut portion. In the center of the other side wall portion, an inverted T-shaped engaging hole is provided. In the lower portion of the engaging hole, a trapezoidal crotch portion protrudes outward in the short-side direction of the bottom wall portion.

The belt portion has a belt shape having a large width, and one end portion side of the belt portion is curved along the upper surface of the claw portion of the sensor holder, and the front end is integrated with the upper surface of the bottom wall portion. A T-shaped reinforcing plate is provided at the distal end of the other end portion of the belt portion, and the T-shaped reinforcing plate is engaged with the engaging hole of the sensor holder, and a fastening screw is attached thereto. The front end of the fastening screw abuts against the crotch portion of the sensor holder.

The creative feature of this design is the overall shape of the sensor mount.
