摘要： A rotating cylinder includes a cylinder body, a piston, a piston shaft assembly, a main body and a guiding assembly. The cylinder body defines a receiving chamber. The piston, the piston shaft assembly, the main body and the guiding assembly are received in the receiving chamber. The piston shaft assembly is fixed to the piston, and defines at least one guiding groove lengthwise thereof. Each guiding groove includes a spiral portion and an extending portion. The main shaft is non-rotatably connected to the piston shaft assembly away from the piston and exposed out of the cylinder body. The guiding assembly sleeves on the piston shaft assembly and is slidably connected with the at least one guiding groove. The main shaft is driven to rotate when the guiding assembly engages the spiral portion, and move lengthwise when the guiding assembly is slidably connected with the extending portion.

摘要： An annular piston (21) is inserted into a cylinder hole (20) of a housing (4) so as to be vertically movable and be prevented from rotating. Into a cylindrical hole (24) of the piston (21), a cylindrical rotating member (25) is inserted while prevented from moving vertically. A ball screw mechanism (28) is provided between the piston (21) and the rotating member (25). On an outer peripheral surface of the rotating member (25), a circulation passage (59) which communicatively connects a start end and a terminal end of a male spiral groove (56) is formed in a recessed manner. Into a guide hole (29) formed in an upper half of the housing (4), an output rod (30) is inserted rotatably and movably vertically. An input portion (41) of the output rod (30) is connected to the rotating member (25) so as to transmit rotation. By driving the piston (21) upward, a bolt (45) provided on an upper end portion of the output rod (30) is engaged with an internal threaded hole (12) of a work (10).

摘要： According to a rotary clamp cylinder of this invention, in a rod cover 5, attachment holes 18 are formed so as not to intersect an axis CL of a piston rod 11, and pin members 19 are rotatably fitted in the attachment holes 18, respectively. An amount L of engagement between each pin member 19 and each turning guide groove 14 becomes greater, on the side of the axis CL of the piston rod 11 in the pin member 19 than on the side opposite to the side of the axis CL of the piston rod 11, and the outer circumferential face 21 of each pin member 19 on the side opposite to the side of the axis CL of the piston rod 11 can be supported by the inner face of each attachment hole 18, over substantially the entire length thereof. Accordingly, excessively large load and/or impact could be received by the pin members 19, as such the increase of the transfer speed upon clamping or unclamping, and/or attachment of a longer clamper 12 to the piston rod 11 can be further facilitated.

摘要： The invention relates to a linear, hydraulic pivot drive, especially for the flap control system of aerodynamic structures. Said pivot drive comprises a housing provided with ports for introducing a hydraulic medium, a piston which is arranged inside the housing and can be axially displaced by the effect of the hydraulic medium, and an output shaft which is provided with coarse threads and interacts with the piston in order to cover the axial displacement of the piston into a rotational movement. The invention is characterized in that the output shaft is integrated into the piston, the coarse threads running in the same direction and engaging in the piston, and the cross-section of the piston has a spline profile for effectively preventing a rotational movement of the piston.
