摘要： A clamping device for frictional clamping of a workpiece which includes a clamp element adapted to frictionally clamp a workpiece and a mechanism for moving the clamp element which includes a shape memory alloy adapted to move the clamp element when the shape memory alloy is heated. The shape memory alloy moves the clamp element into a clamped state and/or unclamped state upon heating the shape memory alloy. The clamped element is preferably a super elastic alloy which is naturally oriented in a clamped position for a positive clamp and in an unclamped position for a non-positive clamp.

摘要： An actuation apparatus for positioning a workpiece includes a movable electrically conductive member connectable to said workpiece, first electromagnetic actuating means energizable by a first AC voltage source to produce a first force acting on said movable member in a first direction, and second electromagnetic actuating means energizable by a second AC voltage source to produce a second force acting on said movable member in a second direction opposite to said first direction. The forces produced on the movable member by the actuating means are brought about by the interaction of eddy currents induced in the movable member with the magnetic fields produced by the first and second actuating means. The movable member can be moved to a desired position by appropriate energization of the first and second actuating means such that the first and second forces are equal at the desired position.
摘要翻译：用于定位工件的致动装置包括可连接到所述工件的可移动导电构件，第一电磁致动装置，其由第一AC电压源激励，以产生在第一方向上作用在所述可动构件上的第一力，以及可激励的第二电磁致动装置通过第二AC电压源产生在与所述第一方向相反的第二方向上作用在所述可移动部件上的第二力。通过致动装置在可动件上产生的力是由可动件中感应的涡流与由第一和第二致动装置产生的磁场的相互作用引起的。通过第一和第二致动装置的适当通电，可移动构件可以移动到期望的位置，使得第一和第二力相等于期望的位置。

摘要： A machine vise is provided with a body having a fixed jaw and a movable jaw which may be moved toward the fixed jaw by means of a tractively acting hollow screw spindle. A force amplifier is arranged below the fixed jaw and is operable by a pushing rod shiftably inserted in the hollow screw spindle. A common driving device rotates the screw spindle into and away from its clamping position. Upon a predetermined clamping force being exceeded the force amplifier is activated by the pushing rod. The movable jaw may be split in upper and lower portions.

摘要： A guide bar for carrier strip grips the strip ribbon between adjustable pins and can accept a wide range of strip dimensions. The pins project from spring-actuated disks that are recessed into the upper surface of a slide bar. Associated gears at the undersurface of the bar cause pairs of the disks to turn in unison.

摘要： A workpiece clamping device with a movable clamp member actuated by a jack screw driven by a reversible electric motor through a worm meshing with a gear connected to the jack screw. To yieldably bias the clamp member into engagement with the workpiece, a spring is compressed by axial movement of the worm caused by rotating it after the clamp member is forced into engagement with the workpiece by the jack screw.

摘要： This invention is an improved concept of the clamp shown in U.S. Pat. No. 3,736,629, as issued June 5, 1973. This clamping device has two C-shaped arms, each of which is an assembly of two plate-like members of sheet metal. These two arm assemblies are pivotally retained at one end with the plate-like members in an overlay condition. A pivot pin has an enlarged center portion which acts as a spacer and has two eccentric cam areas sized and spaced to actuate apertures formed in one of the arm pairs. Shouldered rivets retain these arm assemblies in spaced array and a stop pin secured in this pivot pin has a length sufficient to engage a secured rivet. At one limit of movement of the stop pin, the cam areas move one arm assembly to a maximum clamping force and, at the other limit of movement of the stop pin, the cam areas are in a reduced-force application. Trunnion blocks are pivotally retained in each arm, with one block having through threads and the other block having a smooth bore adapted to rotatably retain a socket-headed cap screw whose threaded portion is compatibly disposed in the threaded trunnion. Rotation of this screw causes jaw ends having pivoted clamp pads to be brought to and away from each other. The members of this clamp are of metal and the pivot pin and clamp pads may be made by a screw machine and then heat-treated.
摘要翻译：本发明是美国专利中所示的夹具的改进概念。 1973年6月5日公布的第3,736,629号。该夹紧装置具有两个C形臂，每个C形臂是两个板状金属片状部件的组件。这两个臂组件在一个端部以覆盖状态枢转地保持在板状构件上。枢轴销具有扩大的中心部分，其作为间隔件并且具有两个偏心凸轮区域，其尺寸和间隔尺寸以致动形成在一对臂对中的孔。肩部铆钉将这些臂组件保持为间隔开的阵列，并且固定在该枢转销中的止动销具有足以接合固定铆钉的长度。在停止销的移动的一个限制下，凸轮区域将一个臂组件移动到最大夹紧力，并且在止动销的另一个移动极限下，凸轮区域处于减小的应用中。耳轴块枢转地保持在每个臂中，一个块具有通过螺纹，另一个块具有平滑的孔，适于可旋转地保持其螺纹部分相互配置在螺纹轴颈中的插头头螺钉。该螺钉的旋转使得具有枢转夹紧垫的钳口端部彼此相互离开并远离。该夹具的构件是金属的，枢轴销和夹紧垫可以由螺丝机制成，然后进行热处理。

摘要： An engineers' or carpenters' vise comprising a tubular outer member (12) having a plurality of apertures (13) aligned along one side of the member. A jaw is fixed to one end of the member. A second tubular inner member (18) is telescoped within the first member and has a plurality of apertures (19) which cooperate with the aperatures (13) in the outer member. A movable vise jaw (20) is attached to the end of the inner member. A tapered lever (24) is provided for insertion into apertures which are not in line, so as to forcibly pry or move the inner member (18) in either one of two alternative directions. A tapered locking pin (22) is provided to securely lock the inner member (18) to the outer member (12) so as to prevent any return movement. The pin is inserted into apertures which are not in line. The inner member (18) can be removed from the outer member (12) and re-inserted into the opposite end of the outer member, so as to arrange the vise to have an even greater jaw opening.

摘要： A key vise structure is disclosed wherein first and second vises are mounted on opposite ends of the frame and a movable vise jaw in each vise is moved by an end of a beam spring. The central portion of the beam spring is moved toward the vise jaws by means of a mechanical advantage means, shown in the preferred embodiment as a manual handle and a toggle mechanism. This simultaneously clamps both vises closed upon keys for use in a key machine. The key vise structure is also provided with a shoulder gauge for the key with a spring acting to yieldably urge the shoulder gauge into each of a gauging and a retracted position and this shoulder gauge is retracted by linkage means as the vises are moved to the clamped position. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
