Installation structure of the position detection sensor in the fluid pressure cylinder and position detection sensor null for the fluid pressure cylinder

摘要

PROBLEM TO BE SOLVED: To surely fix a position detecting sensor for fluid pressure sensor without giving any damage to the mounting groove of a fluid pressure cylinder and the position detecting sensor. ;SOLUTION: An passing hole 14 is formed into a position detecting switch 2 which is engaged with the mounting groove of an air cylinder in a state where the switch 2 can be moved in the axial direction only at the position facing the mounting groove and holding plates 6 and 7 are fixed to the mounting groove with a fixing bolt 8 which is passed through the hole 14. On the internal peripheral surface of the hole 14, a plurality of supporting pieces 15 elongated in the vertical direction are provided at equal angular intervals in the peripheral direction. Fach supporting piece 15 supports the bolt 8 so that the hole 14 cannot move in the axial direction relatively to the bolt 8, because its inner peripheral side is shaved off when the bolt 8 is screwed in the hole 14.;COPYRIGHT: (C)1998,JPO
