Title:

DEVICE FOR MOUNTING POSITION DETECTING SENSOR

Document Type and Number:

WIPO Patent Application WO/1992/008058

Kind Code:

A1

Abstract:

A device for mounting a position detecting sensor for detecting a stroke of a cylinder. It has such an arrangement that a rotary angle of a magnetic sensor (1) is regulated to within ±5 degrees by a slit (9) formed in a housing (2) mounted thereon with the magnetic sensor (1) and a rotation-locker (7) mounted on a cover (6), the slit (9) allows the housing (2) and the cover (6) to slide on each other, but does not allow the both members to fall off each other, and the cover (6) and a head (4) are aligned with each other by a knock pin (10). With this arrangement, assembling work and highly accurate positioning can be easily performed. Furthermore, according to the present invention, a slit (21) is provided in the top portion of the sensor (1), the position of which can be adjusted by a collar (16) driven thereinto with a pin (17), after the adjusting, the sensor (1) is mechanically pressed by a cover (22) to be fixed or fixed by a mold material, so that an output of the sensor (1) can be controlled to be in an optimal state. Further, a block (20) mounted thereon with the sensor (1) is adjustably installed on a cylinder head (23), the sensor can be set to the position of a magnetic scale with ease, and the sensor (1) and the block (20) can be easily replaced with new ones.
