A work support and method of clamping a translatable component of a hydraulic work support system. The work support may include a rigid, hollow slotted collet, a sleeve, and the translatable component, such as a plunger or rod. Hydraulic fluid may be pumped into an inlet of the hydraulic work support system to hydraulically actuate the translatable component outward from a first retracted position to a second extended position. The hydraulic fluid may further be pumped to the sleeve at a sufficient pressure that the sleeve presses against the collet. The collet responds thereto by flexing into contact with the translatable component, thus holding the translatable component in the second extended position. The slots in the collet allow for flexure even when using a thicker material with stronger column strength.

The positioning pin has a pin body and a biasing element. The pin body defines a slit through which at least a portion of the biasing element is able to extend through. The pin body can be configured to be at least partially inserted into a working surface hole and help position an object. The biasing element has an engagement element that is able to bias the working object in a direction of the slit.

Apparatus and associated methodology contemplating holding a bucket stationary while a user mixes a substance in the bucket. A rigid base is configured to support the bucket upright upon a predetermined holding zone, and supports a selectively rotatable pivot member. A paddle has a proximal end attached to the pivot member and extends therefrom downwardly toward the base on one side of the pivot member. A foot-actuated lever has a proximal end attached to the pivot member and extends downwardly toward the base on the opposing side of the pivot member.

A support rod (3) is inserted in a housing (1) so as to be movable in an up-down direction. An actuation chamber (21) is provided in a lower end portion of the housing (1). An output member (24) is moved upward by pressurized oil supplied to the actuation chamber (21). In the actuation chamber (21), to which pressurized oil is supplied, a release spring (33) is attached between a leading end wall (31) of the actuation chamber (21) and a flange portion (25a) provided to a base end portion of the output member (24). The release spring (33) biases the output member (24) downward.

A fixture for holding a barrel-shaped part, including an interior surface, in a fixed position includes a body configured to fit inside the barrel-shaped part and a support ring coupled to the body. The support ring includes a peripheral channel. The fixture further includes a bladder tube engaged with the peripheral channel of the support ring and inflatable to engage the interior surface of the barrel-shaped part when the body is inside the barrel-shaped part.

An adjustable workpiece support system includes an adjustable support apparatus, an analysis support point module, a coordinate post-processing module and a control module. The adjustable support apparatus has a group of support devices for supporting a supported workpiece, the each support device being adjustable in height and angle. The analysis support point module is used to import a computer-aided design file of the supported workpiece, and analyze the computer-aided design file to obtain a group of support points of the supported workpiece. The coordinate post-processing module is configured to calculate the support coordinates of the each support device corresponding to the group of support points. The control module is configured to receive the support coordinates of the each support device, and adjust the height and angle of the each support device to support the supported workpiece, so that the amount of deformation of the supported workpiece is the minimum.

A fixing jig for fixing a steel material includes a nut, a screw shaft screwed to the nut, a handle attached to the screw shaft, and a contact portion relatively rotatably attached to the handle. A plurality of screw holes are formed in an outer peripheral portion of the contact portion. The first extension member includes a long cylindrical portion, an extension side contact portion provided at a tip end portion of the cylindrical portion, and a connecting portion provided at a base end portion of the cylindrical portion and connected to the contact portion. The connecting portion includes a plurality of through holes formed in an outer peripheral portion of the connecting portion, and long engagement holes each extending from each of the plurality of through holes.
