A dual-cam device is described configured to be engaged with a rail and a stopper for clamping at least one object. The dual cam device comprises a jaw; a body; a member connecting the jaw and the body wherein the member has a member-base configured to associate with and slide on the rail; and a lever pivotally connected to the member, wherein the lever has a first cam and a second cam and wherein the lever is configured to be tilted from an open position to a clamp position and vice versa. During tilting the lever from an open position to a clamp position in which the object is clamped, the first cam causes the dual cam device to secure emplacement position of the dual cam device to the rail and then the second cam causes the dual cam device to press and clamp the object by the jaw against the stopper. It is further described a clamping apparatus that comprises at least one dual cam device; at least one rail having a channel; and at least one stopper.

The present invention relates to a method, and an arrangement for attaching a lens to a lens holder. The method comprises: arranging a fixing arc of a fixing part around a compressible retainer of the lens holder, inserting an attachment portion of the lens into the compressible retainer, and reducing a radius of curvature of the fixing arc, such that the compressible retainer of the lens holder is compressed around the attachment portion, thereby attaching the lens to the lens holder.

The present invention relates to a bonding apparatus for a power terminal of a heating plate, for bonding the power terminal supplying power to a heating wire of a substrate. The bonding apparatus for a power terminal of a heating plate comprises: a chamber; a stage which is disposed in an inner space of the chamber and on which the substrate is placed; an upper press portion disposed in the inner space of the chamber to face the stage, provided to be vertically movable, and having a terminal fixing portion configured to fix the power terminal; and an elevating driver configured to move the upper press portion up and down, wherein the terminal fixing portion further includes a magnetic holder configured to hold the power terminal by a magnetic force.

A gunsmithing block is disclosed. The gunsmithing block has a first end for interfacing with a vice, and a second end shaped to interface with an upper receiver assembly of a firearm, the upper receiver assembly having an upper receiver, a bolt carrier without a bolt, and a barrel extension. The second end has an upper receiver mating portion shaped to interface with an interior region of the upper receiver and an interior region of the barrel extension. Methods of using and making a gunsmithing block are also disclosed.

The present invention relates to a turntable mechanism, including a flat plate and a rotating device for driving the flat plate to rotate, where the flat plate rotates to generate a negative pressure between a lower surface of the flat plate and a surface of an adsorbed object, the flat plate and the adsorbed object adhere together by an adsorption force generated by the negative pressure, and in this case, a gap is kept between the lower surface of the flat plate and the surface of the adsorbed object. In the present invention, a continuous, consistent, and stable fluid film is formed between the turntable and the adsorbed object, and a secondary flow is not easily generated, thereby ensuring that the adsorption force between the rotating flat plate and the adsorbed object is more stable.

An end cap holder includes a main body and a pump which generates a vacuum pressure. The main body includes a bore hole extending therethrough along a central axis, and a contact surface which surrounds an end of the bore hole. Activation of the pump may generate a vacuum pressure within the bore hole.

A system for supporting workpieces during machining. The system comprises one or more adjustable workpiece support assemblies and a robotic unit. Each workpiece support assembly comprises a pedestal and a rotatable fixture element. The robotic assembly comprises means of mobilizing and immobilizing each support assembly, so that the fixture element may be secured in a particular orientation. The robotic unit moves along a frame, and manipulates and fixes the position of the fixture elements to match the contour of a workpiece. Vacuum forces may be applied through the workpiece support assemblies to secure the workpiece against the fixture elements.
