Claims

[Claims for Utility Model Registration] A nut body 3 is fixedly held on a piston body 2 which is slidably fitted into the cylinder body 1 so as to move together with the piston body 2, and is screwed onto the nut body 3. A sliding drive mechanism A is constructed by attaching a mating screw shaft 4 to the cylinder body 1 such that it can only rotate freely in a sliding restricted state, while slidingly moving in a direction parallel to the direction of movement of the piston body 2. A second nut body 6 is fixedly held on a movable table 5, which is freely mounted, with its axial direction parallel to the axial direction of the nut body 3, and is screwed onto the second nut body 6. A second screw shaft 7 is mounted so that it can only rotate freely in a sliding restricted state, and a brake 8 and a pulse encoder 9 are mounted on this second screw shaft 7 to create a sliding driven mechanism B.
A fluid pressure cylinder with a positioning control device, characterized in that a mechanism C is provided which interlocks the screw shafts 4 and 7 of both mechanisms A and B. A fluid pressure cylinder with a positioning control device according to claim 1, wherein the interlocking mechanism C is a variable speed gear mechanism. The above-mentioned mechanisms A and B are arranged in a mutual positional relationship such that the movement stroke of the piston body 2 in the sliding drive mechanism A falls within the movement stroke range of the movable table 5 in the sliding driven mechanism B. A fluid pressure cylinder with a positioning control device according to the scope item.
