A clamping device (2) includes: a turning-supporting member (26) formed so as to support a housing (3) which turns when a clamping position is set, the housing (3) turning toward a desired turning angle position about an axis of the housing (3) while maintaining the axis at a constant position; and a bolt (46) which fixes the housing (3) to the turning-supporting member (26) at the desired turning angle position.

The invention relates to a drive transmission for converting a drive movement into an output movement, in particular in a swing clamp (1) for clamping components. The drive transmission according to the invention first comprises a movable drive element (9), in particular in the form of a piston, which carries out the drive movement during operation. Additionally, the drive transmission according to the invention has a movable output element (4), in particular in the form of a rod, which carries out the output movement during operation, and a cam gear, which converts the drive movement of the drive element (9) into the output movement of the output element (4) according to a specified transmission curve, wherein of the drive movement and the output movement, one movement is or contains an axial movement along a specified movement axis while the other movement is or at least contains a rotational movement about the movement axis. According to the invention, the cam gear has two contact surfaces (F1, F2) which slide against each other in a planar manner and thereby convert the drive movement.

Modular carriage for varying spacing between ends of polymer pipe during fusion. The modular carriage includes a fixed jaw; an inner movable jaw; an outer moveable jaw and a plurality of guide rods. The fixed jaw being adapted for tool free engagement with the terminal ends of the plurality of guide rods. A carriage cylinder is associated with at least two of the guide rods and mounted for reciprocal travel along the length of its associated guide rod. The movable jaws being adapted for tool free engagement with at least two carriage cylinders for reciprocal travel therewith. A combined hydraulic cylinder/guide rod includes a guide rod with an integral guide rod piston, a cylindrical tube, and a guide rod gland on each end of the cylinder tube.

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

A clamping device and a machining method. The clamping device comprises: a base; a clamping head comprising a blind rivet and a locking member, the blind rivet comprising a middle column segment and enlarged portions at two ends, and the locking member being connected to an upper end of the blind rivet and defining a clamping opening; a lower cavity connected to the base; an upper cavity comprising an annular peripheral wall and a top wall having a central hole, the top wall being clamped between the two enlarged portions, the middle column segment of the blind rivet movably passing through the central hole, and the upper cavity being connected to the lower cavity in a fit manner; an elastic member located in the peripheral wall and supported between the enlarged portion at a lower portion of the blind rivet and the top wall; and a support cylinder movably fitted in the lower cavity, the support cylinder being supported below the elastic member.

An output rod (20) of an electric clamping device includes: a tubular power transmission member (25) screw-connected to a decelerator (6); and an output rod main body (24) disposed radially inward of an inner peripheral surface of a cylindrical hole of the power transmission member (25) with a clearance between the output rod main body (24) and the inner peripheral surface. The output rod (20) further includes: a rotation preventing mechanism (26); a lock-side driving mechanism (27, 42), a release-side driving mechanism (28), and an output rod guide mechanism (29).

A clamping system includes a housing, a clamping lever pivotally coupled relative to the housing, a clamping arm pivotally coupled relative to the housing and the clamping lever, and an expandable link coupled to the clamping arm. The clamping lever and the clamping arm are rotatable from an open position to a closed (clamped) position. A method of mounting a device on a substrate using the clamping system is also provided.

A swing clamp includes a body with a first end and second end. The body defines a bore through the first end and a cavity at the second end. The bore is in communication with the cavity. A plunger is slidably and rotatably held in the body bore. A lever is pivotally connected to the second end. A link arm pivotally connects between the plunger and the lever. A housing includes an attachment portion and a cylindrical portion. The cylindrical portion includes a bore to enable passage of the plunger. A groove is formed in an inner surface of the bore. The groove guides a pin coupled with the plunger. A clamp finger is secured on the end of the plunger. The clamp finger rotates as the plunger is moved in the bore.

A piston (4) is inserted in a housing (1) so that the piston (4) is vertically movable. A housing hole (5) is vertically provided in the piston (4), and an output rod (6) is inserted in the housing hole (5) so that the output rod (6) is vertically movable. A converting mechanism (22) converts vertical movement of the piston (4) into rotary movement of the output rod (6). A guide groove (28) is provided in a circumferential direction on an inner circumferential wall of the housing hole (5), and a stopping part (29) is provided at an end part, in the circumferential direction, of the guide groove (28). An engaging member (31) which is provided on an outer circumferential wall of the output rod (6) is caused to face the stopping part (29) of the guide groove (28) at a given distance in the circumferential direction from the stopping part (29) so that the engaging member (31) can be in contact with the stopping part (29).
