摘要： A blade holding jig for holding a washer-type cutting blade via an annular retainer flange includes an annular flange holding portion configured to hold a first annular surface of the retainer flange under suction, and an annular non-contact suction portion arranged on an outer peripheral portion of the flange holding portion and configured to produce a negative pressure by ejection of a fluid toward the outer peripheral portion of the retainer flange held by the flange holding portion and to draw up the cutting blade toward the retainer flange. The cutting blade drawn up toward the retainer flange by the non-contact suction portion is held on the retainer flange by a suction force acting from the flange holding portion via a plurality of through holes disposed extending from a second annular surface to the first annular surface of the retainer flange.

摘要： An expansion clamping device includes a base body and an expansion socket. The expansion socket is inserted into the base body to form a pressure chamber. The pressure chamber can be applied with a hydraulic medium while elastically deforming the expansion socket, in order to achieve a clamping effect in a receiving space which is open in the axial direction of the base body towards a face side and is surrounded by the expansion socket in the circumferential direction. The expansion socket has an elastically deformable clamping section and a collar projecting outwardly in the radial direction on the face side. The expansion socket bears with a bearing surface of the collar in the axial direction against a contact surface of a contact shoulder of the base body and, at least in the region of the bearing surface, is firmly connected, in particular by a material bond, to the base body. The clamping section transitions into the collar in a transition region, a recess being formed in the expansion socket in the transition region in such a way that the transition region overlaps over the contact shoulder of the base body in regions, the bearing surface of the expansion socket bearing against the contact surface in a radially outer contact region thereof, and the contact surface having a radially inner free region adjacent to the contact region, in which free region the expansion socket does not bear against the contact surface.

摘要： An expander unit of a cryogenic refrigerator device includes a moving assembly with a porous regenerative heat exchanger configured to move back and forth along a longitudinal axis. A magnetic spring assembly includes a stationary magnetic assembly fixed to the cold finger base that includes one or more magnetic rings fixedly arranged about a bore. A movable magnetic assembly includes one or more movable magnetic rings fixed to the moving assembly. An outer lateral dimension of each of the movable magnetic rings is less than an inner lateral dimension of the bore. The stationary magnetic assembly and the movable magnetic assembly are configured such that, when the moving assembly is displaced along the longitudinal axis from an equilibrium position, attractive and repulsive forces between the movable magnetic assembly and the stationary magnetic assembly yield a restoring force that is directed to restore the moving assembly to the equilibrium position.

摘要： A drive system for driving a chuck device including a piston and a pair of fingers to be opened and closed according to the displacement of the piston, includes a controller, a detection sensor to detect an axial position of the piston, and three-port servo valves to switch a state of supply of the fluid to the chuck device. A degree of valve opening is controllable based on a control signal input from the controller, and an amount of displacement of the piston and an amount of opening and closing of the fingers are controlled by changing the degree of valve opening. One of the 3-port servo valves is connected to a first cylinder chamber of the chuck device, and another of the 3-port servo valves is connected to a second cylinder chamber of the chuck device.

摘要： A blade changer unit includes a blade chuck for holding a cutting blade, a moving unit for moving the blade chuck, and a control unit for controlling moving unit. The blade chuck has a plurality of electrically conductive grippers for holding the cutting blade. The controller detects conduction between the grippers and a boss. The control unit includes a calculator for calculating the position of a central axis of the mount from coordinates where the conduction between the holder and the boss is detected when the moving unit is controlled to bring the grippers into contact with the mount at at least three points, and a mounting/dismounting controller for mounting and dismounting the cutting blade while the central axis of the blade chuck is aligned with the central axis of the mount calculated by the calculator.

摘要： The present invention provides an apparatus for working oppositely arranged first and second surfaces of a pressing section. The apparatus comprises an upper working unit forming a top wall and an upper sidewall extending downwardly from the top wall; a lower working unit forming a bottom wall and a lower sidewall extending upwardly from the bottom wall; and an inflatable bellows movable between an inflated state and a deflated state by inflation with an inflation medium. The upper sidewall is arranged to guide the lower sidewall to thereby form an internal space enclosed by the top wall, the bottom wall, the upper sidewall, and the lower sidewall. The inflatable bellows is arranged in the internal space to facilitate variation of the distance between the top wall and the bottom wall during relative movement between the upper sidewall and lower sidewall by inflation of the inflatable bellows.
