The present invention relates to a clamping assembly for clamping an extruded profile with a contour on a milling machine, comprising: a fixed clamp, a movable clamp, and a die assembly, wherein the die assembly comprises two or more form blocks, wherein the form blocks are provided on a support plate, and wherein the form blocks are provided between the fixed and movable clamp, wherein the form blocks have a contour that is complementary to separate, non-contiguous, parts of the contour of the profile at rest, and wherein the clamps are configured to move the form blocks towards each other for the clamping engagement of the profiles. The invention also relates to a method for clamping an extruded profile on a milling machine.

A gripper (2) for gripping a workpiece (28) includes a jaw assembly (4, 6) having an actuator with a housing (18, 20, 22) and an elongate member axially slidably movable within the housing. A force-multiplying mechanism (203b, 209, 201b) is interconnected between the elongate member and the housing. The force-multiplying mechanism is configured to add a mechanical force to the jaw assembly and thereby increase a gripping force on the workpiece during operation of the gripper.

A wheel clamp attaches to a vehicle wheel for performing a wheel alignment on the vehicle. The wheel clamp has a body for supporting a target or measuring head, and three extendable arms slidably mounted to the body. Each arm has a gripping portion for gripping the tire's tread surface and a sidewall contact portion for contacting the tire sidewall such that the clamp body is substantially parallel to the vehicle wheel and the wheel clamp has no contact with the rim. A self-centering linkage has enmeshed gears and link arms respectively connecting the arms to the gears, such that when the gears are rotated, the arms simultaneously proportionally slide relative to the clamp body, so the gripping portions of the arms engage and grip the tire tread surface and tighten the clamp onto the tire, while the sidewall contact portions of the arms contact the tire sidewall.

The invention relates to a device comprising supports (3, 4) which can be moved relative to each other and on the mutually facing walls of which toothed profiles (6, 7) are provided. Each said toothed profile interacts with opposing segments (31, 32) of a rotatable gear (2), by means of the rotation of which the supports (3, 4) can be moved in opposite directions simultaneously in a synchronized manner. The gear (2) has a varying tip circle diameter (d) along the gear circumference, wherein the tip circle diameter (d) increases along a segment (31, 32), and an effective outer diameter (d w ) of the gear (2) is arranged between the supports (3, 4) in a clamped rotational position, said effective outer diameter (d w ) matching a target diameter.

A vice has a second pair of jaws (110,210) attached one to the body (1) and the other to the slide (2). The two pairs of jaws may differ in opening width or shape. The inner jaw (11,110) of each pair may be attached to a swivel, so that they can be exchanged, and with means (17,115) for locking then in positions. Alternatively, the second pair of jaws may be formed by toothed edges (18,28) of cut-away part of the slide and body.

A lift fixture (10) for holding and centering a workpiece (93) includes a handling ring (16) defined by a yoke (17) and a clamp slide (20) mounted on the yoke, means (48) for closing the clamp slide (20), a support apparatus (12) for positioning the handling ring (16), and a plurality of angularly spaced holding mechanisms (33,34,40,41) for gripping the workpiece (93). The holding mechanisms (33,34,40,41) are movably mounted to the handling ring (16) so as to move relative to the ring along a line generally tangent to the workpiece (93). The holding mechanisms (33,34,40,41) are biased to a centered position, as by springs (87,88), so that when the workpiece (93) is lifted, it is urged to a centered position within the ring (16).
摘要:
Um eine Spannvorrichtung zum Einspannen eines an einem Werkstück oder an einem Werkstückträger angeordneten Spannbolzens, wobei die Spannvorrichtung Verriegelungselemente, einen Kolben zum Bewegen der Verriegelungselemente zu einer Längsmittelachse der Spannvorrichtung hin, ein erstes Gehäuseteil und ein zweites Gehäuseteil und eine Vorspannvorrichtung zum Spannen des Kolbens in eine Spannstellung des Kolbens umfasst, zu schaffen, welche es ermöglicht, auch ohne Verwendung größerer und stärkerer Federelemente eine höhere Vorspannkraft zu erzeugen, welche den Kolben in seine Spannstellung vorspannt, wird vorgeschlagen, dass die Vorspannvorrichtung einen Zwischenkolben umfasst, welcher sich bei einer Bewegung des Kolbens von einer Freigabestellung in die Spannstellung zumindest abschnittsweise in der gleichen Richtung wie der Kolben bewegt, und dass die Spannvorrichtung Verstärkungselemente umfasst, welche zumindest einen Teil der Vorspannkraft von dem Zwischenkolben auf den Kolben übertragen.
