A fixture for supporting a workpiece during a machining operation is disclosed. The fixture may include a seat configured to receive the workpiece. The fixture may further include a quick release lever mounted to the fixture and configured to displace the workpiece from the seat.

A fixture for holding a part comprises a frame supporting a guide plate. A controlled engagement device passes through the guide plate and is arranged to be advanced incrementally towards a first end of a fulcrum beam. A second end of the fulcrum beam is connected to a linkage arm, the linkage arm passing through a gap in the guide plate. An end of the linkage arm distal to the fulcrum beam has a swivel clamp mounted thereto. A support is arranged to face the swivel clamp and defines a space there between, the space being configured to receive a part to be clamped in the fixture.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

The invention to which this application relates is a clamping mechanism of a type which is adapted to be used with a base (4). The apparatus (2) is provided for use in conjunction with a base (4) to exert a clamping effect on a workpiece (13) with respect to the base (4) and the clamp apparatus (2) includes an elongate shaft (14), a locating portion (52, 6) provided at, or towards one, end of the said shaft, a user operated actuation means selectively located between the said locating portion (52, 6) and the opposing end of the elongate shaft (14). The actuation means are provided with, or connected to, a clamping portion (12) and the locating portion (52, 6) is provided to allow location of the clamp apparatus (2) with respect to engagement means provided on the base (4).

The invention to which this application relates is a clamping apparatus (2, 52, 86) adapted to be used with a base (16) and to clamp (70) a workpiece (36, 38) in position with respect to a surface (38) of said base (16). The apparatus (2) includes an elongate shaft (60), at least one locating portion (10, 88) and engagement portion provided at or towards one end of the said shaft (60), a user operated actuation means selectively located between the said locating portion (10, 88) and the opposing end of the elongate shaft (60), said actuation means provided with, or connected to, a clamping portion and the base (16) includes one or more ports (18) or tracks with which the said locating portion (10, 88) and engagement portion is selectively located so as to selectively position the clamp (70) apparatus (2) with respect to the base (16).

A cuff-blade attachment bushing removal tool system includes an alignment plate comprising alignment holes defined through the alignment plate in a pattern of a plurality of bushing holes of a blade root, a bladder plate connected to the alignment plate, and a bladder positioned on the bladder plate such that a gap is formed between the bladder and the alignment plate to receive a blade root to align the alignment holes and the bushing holes of the blade root, wherein the bladder is transitionable between an uninflated position where the blade root can be inserted into the gap and an inflated position where the blade root is clamped between the bladder and the alignment plate.

A power tool and operation method for quick locking and releasing working attachment thereof are provided. The power tool includes a housing; a motor in the housing; an output shaft driven by the motor; and a chuck to lock and release a working attachment, said chuck including a chuck body coupled with the output shaft, jaws movably disposed relative to the chuck body, and a clamping sleeve outside the chuck body. The clamping sleeve is movable with respect to the chuck body so as to drive the jaws to retract and open relative to the chuck body. A control mechanism is operable to lock the clamping sleeve or the chuck body relative to the housing, and to control the motor initiating along a preset rotary direction so that relative movement between the clamping sleeve and the chuck body is generated.

An anti-pivot and lock mechanism for a clamp including a horizontal post connected and moveable relative to a vertical post. The mechanism engages the vertical post and horizontal post above or below a pivot axis of the horizontal post to prevent or minimize pivoting movement of the horizontal post between changes of consecutive clamped workpieces.

A system for remotely opening and closing a process equipment bolt flange joint may include a hydraulic cylinder actuator assembly for attaching to the flanges of a bolt flange joint to open and close the joint by operation of a remote hydraulic pump. More than one actuator assembly may be evenly spaced around the flange joint, to ensure even distribution of force around the joint. The system may have an accumulator for receiving hydraulic fluid expelled from the hydraulic cylinder during extension and to force hydraulic fluid back into the cylinder to close the flange joint upon pressure release at the pump. A drop trigger may be used to release hydraulic pressure at the pump for emergencies. The system may include a video camera for viewing the joint on a display. The components may be stored and transported on a mobile cart. A method of use is also disclosed.

The utility model relates to the field of a photographing support apparatus, in particular to a clamping device, including: a lower clamping portion, an upper clamping portion corresponding to the lower clamping portion, a clamping arm connecting the upper clamping portion with the upper clamping portion, and a connecting head for connecting a telescopic rod. The clamping device further includes a connecting member arranged on one side of the connecting head. A sliding groove of the clamping arm is provided on one side of the clamping arm far away from a peripheral device. A slider is slidably arranged in the sliding groove of the clamping arm. The connecting member is rotatably connected to the slider. In the clamping device of the utility model, the sliding groove of the clamping arm is arranged on the clamping arm. The slider is slidably arranged in the sliding groove of the clamping arm, so that the connecting member is rotatably connected to the slider. Therefore, after clamping the photographing apparatus, the clamping device can conveniently adjust horizontally a photographing angle. The clamping device itself is easy to be stored, thereby reducing a volume of the self-photographing apparatus, which is convenient to carry and use.
