An apparatus (100) for applying pressure to at least a portion of an edge surface (192), which bridges opposing faces (194) of a workpiece (190), comprises a frame (110), a first roller (120), a second roller (130), a rotation-control member (140), a first biasing member (150), and a second biasing member (160). The first roller (120) and the second roller (130) are coupled to the frame (110), rotatable relative to the frame (110) about a first pivot axis (125), and translationally fixed relative to the frame (110). The rotation-control member (140) is movable relative to the frame (110), controlling rotation of the first roller (120) and the second roller (130) relative to the frame (110). The first biasing member (150) is coupled to the frame (110) and is configured to operate in tension. The second biasing member (160) is positioned, in compression, between the frame (110) and the rotation-control member (140).

A vise includes a vise body having a base with spaced apart rails joined to the base, each rail including a flange with a surface having a slot. A movable jaw assembly is slidable on the surfaces is driven by an actuator supported by the vise. A stationary jaw has a key configured to engage the slots and has a surface facing the movable jaw assembly. Fasteners secure the stationary jaw to the vise body, where all of the fasteners extend through the surfaces of the vise body between the slots and the surface of the stationary jaw facing the movable jaw assembly.

Embodiments disclosed herein generally relate to a pivotable clamp or vise. For example, the vise may clamp or secure a workpiece at a suitable position and/or orientation.

A vise with an adjustable operating angle includes a base member, a front pier and a rear pier disposed on two opposite ends of the base member. A rotary seat mounted onto the front pier and the rear pier. A platform is pivoted to the front pier and the rear pier. A fixed jaw is secured on a rear end of the platform and a movable jaw is movably mounted on the platform. A lead screw is disposed in the platform for driving the movable jaw. A front turntable and a rear turntable are disposed to two opposite ends of the platform and rotatably disposed on the front pier and the rear pier. A front fastening seat and a rear fastening seat are mounted onto the front pier and the rear pier for selectively holding the front turntable and the rear turntable in place.

In a clamping device (1), in particular vice, the clamping device comprising: a housing (2) which is U-shaped in cross-section and in which one or two guideways (8) extending in a linear direction are incorporated, at least one base jaw (11) which is mounted in the guideway (8) and in which an internal thread (12) is provided, and a drive spindle (9) which is rotatably mounted in the respective housing (2), is arranged parallel to the guideway (8) and is driveably coupled to the respective base jaw (11),
the threads (10) worked into the drive spindle (9), through which the torques from the crank are transmitted for the linear displacement of the base jaws (11), should be permanently encapsulated in a watertight and airtight manner irrespective of the position of the base jaws (11) or the drive spindle (9), and on the other hand the adjustment travel (s) of the base jaws (11) or clamping jaws (13) should be as large as possible in order to clamp workpieces with configurations that can be completely different without the need for time-consuming and complicated conversion measures.

This is achieved in that a right-hand thread and a left-hand thread (10) are worked onto the drive spindle (9) in regions, in that the respective thread (10) of the drive spindle (9) is enclosed or encapsulated by a cover sleeve (21), in that the cover sleeve (21) has a right-hand thread and a left-hand internal thread (22), which are driveably coupled to the respective thread (10) of the drive spindle (9), in that a right-hand and a left-hand external thread (23), which is in engagement with the respective internal thread (12) of the base jaw (11), is worked on to the cover sleeve (21).
