The invention relates to a clamping device for a workpiece, comprising a lower clamping element and an upper clamping element which form a workpiece holder.

A clamping device includes two mounting members facing each other, a driver coupled to the two mounting members and at least one clamping module. Thee driver is configured to alternately drive the two mounting members toward and away from each other. The clamping module includes two clamping members mounted on the two mounting members. Each clamping member includes a guide rod, a clamping block, and an elastic member. One end of the guide rod movably passes through a corresponding mounting member. The clamping block is fixed at one end of the guide rod distal from the mounting member. The elastic member is sleeved on the guide rod and positioned between the mounting member and the clamping block.

The present invention relates to a tubular clamp module and a system thereof, and in particular, to a tubular clamp module and a system thereof applicable to a roll material cutting machine. In the tubular clamp module of the present invention, a slope is disposed at a top end of a support, and support rods slide on the slope to support tubular plates to form an appropriate radian, so as to provide a desirable tubular clamping force in combination with the force applied by a pressing belt. In the tubular clamp system of the present invention, a plurality of tubular clamp modules is used and various driving wheels and driving belts are disposed to enable synchronous adjustment of the positions of the support rods and the length of the pressing belt, so as to rapidly complete clamping of rolls having different diameters and provide a desirable tubular clamping force.

A holder, a transport device, and a method of manufacturing a container are described. The container comprises a body that extends along an axis and a flange that extends radially to the axis, and the holder comprises one or more fastening elements that are configured to engage one or more of a top surface, a bottom surface, or a peripheral surface of the flange.

The application is related to adjustable supports for holding objects in one or more desired fixed orientations, including but not necessarily limited to objects that lack uniformity as to size and/or shape and/or weight.

A socket fusion jig includes a pipe saddle and coupling saddle spaced apart. Rotation of a handle causes the pipe saddle and coupling saddle to move laterally relative to one another so that the pipe held in the pipe saddle may be fused to the coupling held in the coupling saddle.

A number of racks which are configured to allow a number of devices to couple thereto are provided. In some embodiments, the racks are for use with a number of medical devices. Devices may be coupled to a rack by clamps. The racks may include a number of connectors which provide power and/or a network connection to devices coupled thereto. The racks may include a clamp which allows the racks to couple to a supporting structure such as a pole.

An apparatus for aligning sections of pipe includes a first clamp member and a second clamp member coupled with the first clamp member. The first and second clamp members each include a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw. Each one of a first plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the first clamp member, and each one of a second plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the second clamp member. An assembly made from a kit of components is also disclosed. The kit includes an apparatus for aligning sections of pipe, and a plurality of shoe inserts. The assembly includes the apparatus and at least two of the shoe inserts coupled with the apparatus.

A device (100) for capturing, centring, gripping and/or securing an object (140) is disclosed. The device comprises a hub (101) and a ring (102) which are concentric and arranged rotatably relative to each other. On the hub there is at least one first control point (111, 111′, 111″), and on the ring there is at least one second control point (112, 112′, 112″), which control points are arranged at different axial levels (151,152). At least one tensioning member (121,122,123) is arranged to interact with the at least one first control point and with the at least one second control point during the rotation, such that the at least one tensioning member is stretched across the air gap (130) in the device. The different axial levels for the at least one first control point and the at least one second control point mean that the at least one tensioning member can freely pass over the at least one first control point during the rotation and can be stretched across the air gap towards the object. Substantially any desired angle of rotation between the hub and the ring can be obtained in this way.

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.
