The device (1) for locking workpieces on machine tools comprises: a first hydraulic cylinder (2) inside which at least one piston (3, 4) is inserted slidably along a main line (A); a second hydraulic cylinder (15) inside which the first hydraulic cylinder (2) is inserted slidably along the main line (A), the feeding of a pressurised hydraulic fluid into a first chamber (8) being designed to apply to the first hydraulic cylinder (2) a primary force (F) that shifts the first hydraulic cylinder (2) from a home position to a second operating position; an auxiliary chamber (28) provided between the first hydraulic cylinder (2) and the second hydraulic cylinder (15) and associated with pneumatic feeding means (29, 30, 31) designed to feed pressurised air into the auxiliary chamber (28), the feeding of the pressurised air applying to the first hydraulic cylinder (2) an auxiliary force (Fa) along the main line (A) in the same direction as and operating in conjunction with the primary force (F).

The present disclosure provides a fixture for fixing a steering knuckle in a machining process, the fixture comprises a bottom plate, wherein the bottom plate is machined with two bottom plate windows that are configured to accommodate machined parts of the steering knuckle; three groups of pressure claws and three groups of locating pins are fixed on the bottom plate, and the pressure claws and the locating pins are respectively fixed to the through holes of the bottom plate; and the three groups of pressure claws are respectively arranged at three vertexes of a triangle.

A clamp device is equipped with a clamp body, a piston rod, a link mechanism, a detection mechanism for detecting a state of rotary motion of a clamp arm, and a determination unit for determining whether a state of clamping exists. The detection mechanism includes a first proximity sensor, and a knuckle joint having a first sloped surface. The determination unit, on the basis of a comparison of an output signal from the first proximity sensor to a clamp threshold value, determines whether a state of clamping exists, and on the basis of a comparison to a clamping force generation threshold value, determines whether a state of generation of clamping force exists.

A clamping apparatus includes a shaft; a base body that is adjustable to different positions, e.g., heights, along the shaft; a clamping leg arranged to pivot into a first clamping position and a second clamping position; an arm that includes, and extends between, a first end portion connected to the base body and a second end portion connected to the clamping leg; and a handle configured to be moved (a) into a first position that locks the position of the base body relative to the shaft and provides a clamping force to the clamping leg, and (b) into a second position in which the base body is free to be shifted into different positions along the shaft, where moving the handle into the second position releases the clamping force.

A quick grip pocket hole jig system is presented having a support section having a clamp support, an end stop and a back stop. A clamping assembly is connected to the support section having a clamping rod that extends through the clamp support. A drill guide carrier having a drill guide assembly is connected to the clamping rod on a forward side of the clamp support. A clamp body having a trigger and a release mechanism is connected to the clamping rod on a rearward side of the clamp support. The clamp body is a quick grip clamp body that facilitates quick gripping of a workpiece positioned within the support section. The clamping assembly includes a return spring and a release mechanism such that when the release mechanism is actuated the drill guide carrier and the drill guide assembly are automatically moved to a non-clamping position.

A clamp of a bicycle workstand includes a base, an elastic unit, an operating arm, a link unit, and a clamping unit. The base has an accommodating trough. The elastic unit has a shaft sleeved with a spring and a slide and disposed in the accommodating trough. The clamping unit has a fixed clamp body disposed on the base, and a movable clamp body pivotably connected with the base and the operating arm. The link unit has a first link and a second link pivotably connected with each other and pivotably connected with the operating arm and the slide respectively. The second link has a cam. Pulling the operating arm can drive the first and second links to swing. The cam is abutted on the shaft and presses it by rolling. The fixed clamp body and the movable clamp body can be coupled for stable clamping.

Query unit for determining the status of moving or movable parts of a system part, particularly for determining the end positions of a clamping arm of a toggle lever clamping apparatus, has a sensor unit and an electroblock. The sensor unit has at least one sensor and a connector plug-in connection part for connecting the sensor unit with the electroblock and can be attached to the system part. The electroblock has at least one electrical connector element for connecting an outer, releasable connection cable, a connector plug-in connection part for connecting the electroblock with the sensor unit, and at least one screw passage opening for installation on an outer surface of the system part. The connector plug-in connection part of the sensor unit is connected in an opening of the system part, with shape fit.
