A fluid pressure cylinder has a sensor attachment tool mounted thereon. A holder holds the position sensor in a rail structure extending in an axial direction of a cylinder tube and is secured by screwing to a rod cover or a head cover in an arm part provided to one end of the holder.

Sensor attachment tool and fluid pressure cylinder

A sensor mounting tool includes: a rail-shaped sensor holder having a first side wall in which a first connection hole is formed; a band part that has a first projection part, and that is formed to be wound on the outer peripheral surface of a cylinder tube; and a fastening mechanism that is for fastening the band part, and that is arranged at a position shifted away from the sensor holder on the outer peripheral surface of the cylinder tube.

Sensor mounting tool

Sensor mount assembly

A sensor attachment tool is provided with a rail-shaped sensor holder having a sensor insertion groove for accommodatably holding a position sensor so that the position of the position sensor can be adjusted, a band part linkable at both ends to the sensor holder and configured so as to be fitted over the outer peripheral surface of a cylinder tube along the peripheral direction, and a tightening mechanism for tightening the band part, the tightening mechanism being arranged on the outer peripheral surface of the cylinder tube in a different peripheral position than the sensor holder.

Sensor attachment tool

A position sensor attachment band configured to secure a position sensor on an outer periphery of the cylinder tube includes a thin plate band, the thin plate band has one or more projections that project from the inner peripheral surface of the thin plate band which are disposed at least at the end positions among the end positions located in proximity to one end and the other end of the thin plate band in the length direction and the intermediate position, and the projections are disposed at positions completely within the width of the thin plate band and accordingly at positions completely away from the both side edges of the thin plate band on both sides in the width direction, and the projections are symmetrically arranged with respect to the center in the length direction of the thin plate band.

Position sensor attachment band

A sensor holding member holding a position sensor and an attachment member that attaches the sensor holding member to a cylinder tube are formed separately. The sensor holding member is placed with a sensor attachment groove oriented in the direction of the axis of the cylinder tube and in contact with the outer surface of the cylinder tube. The attachment member is placed so as to straddle the sensor holding member. By tightening an attachment screw and fixing the attachment member with an attachment band, the sensor holding member is pressed against and fixed to the outer surface of the cylinder tube by the attachment member. Loosening the attachment screw allows the sensor holding member to be displaced relative to the attachment member in the direction of the axis of the cylinder tube.
