There is provided a piping structure of a front work machine which prevents an increase in total width of the front work machine caused by hydraulic piping extended from the main machine side, and enables the piping following a structure of the front work machine turning vertically, by which a burden on the hydraulic piping accompanying the turning of the front work machine can be reduced to improve the durability. In the piping structure of the front work machine mounted on the main machine through a bracket(s) 7 as a turnably-supporting part(s) arranged on one side of a bonnet provided in a front portion of the main machine or both right and left sides, each of lift arms 11 or a lift arm 11, which is a constructional member of the front work machine, is provided with a hole part 20 through which the hydraulic piping 30 passes.

A connector assembly (46) comprises a housing (60) and a tensile member (62) disposed within the housing (60). The tensile member (60) comprises first and second end portions. Each end portion sealingly engages the housing (60) to form a hydraulic chamber (72) therebetween. A first connector (64) is pivotally coupled to the first end portion. The axial position of the first connector (64) relative to the housing (60) is controlled by pressure within the hydraulic chamber (72).

A vehicle framing system (10) for framing an automotive vehicle body from a plurality of separate body components wherein the body components each include a reference surface. The system includes an assembly station (16) having spaced-apart frame members (22) positioned so that, when a vehicle carrier (14) supporting the vehicle body components is positioned at the assembly station (16), the frame members (22) extend along opposite sides of the vehicle carrier. At least two docking stations (26) are secured to each frame member (22) at predetermined locations. A robot (50) mounts its associated tool arm (40) with a docking station (26). At least one set of reference block (60) and framing clamp (64) is secured to each tool arm and these framing clamps (64) maintain the reference surfaces of the vehicle body components against the reference blocks (60) to hold the vehicle components at a predetermined position relative to each other. After each robot (50) positions each associated tool arm (40) with the docking station (26), the robot (50) disengages from the tool arm (40) and then welds the body components together by a welding gun (70) carried by the robots.
摘要:
The apparatus (22) and method for releasably joining first (14) and second (18) elements according to the present invention include a retaining member (24) mounted to one of the elements and a reshapeable tube (26) near the retaining member. The reshapeable tube (26) has at least two states, an at least partially collapsed state and an at least partially expanded state. As such, the retaining member (24) joins the elements (14, 18) while the reshapeable tube (26) is in the at least partially collapsed state. Furthermore, the retaining member (24) releases the other element (14) while the reshapeable tube (26) is in the at least partially expanded state, which deflects the retaining member (24). Thus, because components of the apparatus (22) are not broken during the release of the elements (14, 18), the amount of constrained or potential energy that is released when the retaining member (24) releases the elements is substantially reduced or eliminated, which protects the elements (14, 18) from being damaged during the release.

Hydraulic clamp bushing (13, 14) of the type comprising a double walled sleeve (7), a hydraulic pressure medium which is trapped in a chamber (5) between the sleeve walls, and means for pressurizing said pressure medium, and in which one of, or both sleeve walls (7) is/are formed for expanding radially outwards and/or inwards when the pressure medium is pressurized, whereby the clamp bushing is clamped to a shaft, a hub or a similar object, in particular a rotary shaft (17, 18), and in which the pressure medium chamber (5) is formed with angularly inwards or sigma formed bushing ends (9) designed so that said ends are straightened up as a first stage when the clamp bushing is pressurized, whereby the axial ends of the bushing facing the shaft (17, 18) are pressed to the shaft (17, 18) thereby providing a straightening up of the bushing (13, 14) on the shaft before the intermediate portions of the sleeve are pressed to the shaft (17, 18).

Hydraulically actuatable friction clamp coupling of the type which can be used for clamp connecting a hollow shaft (2) to a drive shaft (3) and which comprises a shape deformable inner ring (4) which is adapted to engage the sleeve or the hollow shaft (2), and which, at the outer surface thereof, is formed as a double, counter directed screw having two screw portions (8, 9) which meet substantially at the longitudinal centre of the inner ring (4), and the screw flange sides of which have the shape of saw tooth formed cone surfaces (10) as seen in an axial cross section, and two outer rings (5, 6) which, at the inner race thereof, are formed with screw like cone surfaces (11) which are saw tooth shaped in a cross section view, and which match the cone surfaces (10) of the inner ring (4), and in which the two outer rings (5, 6) in form, in common, an intermediate, sealed pressure chamber (14) which is filled with a hydraulic pressure medium adapted to be pressurized from an internal or external source of pressure (7), whereby the outer rings (5, 6) are being pressed apart and the inner ring (4) is being compressed thereby clamping the hollow shaft (2) onto the drive shaft (3). Means are provided for mechanically blocking the outer rings with full clamp action in their moved-apart conditions.

摘要:
A frictional revolving joint (72) for joining a hub to a shaft (70) has a tapered ring arrangement (52) with two tapered ring sections with conical outer surfaces that have a V-shaped cross-section and a clamping ring made of two clamping ring elements that enclose the tapered ring arrangement. The ring-shaped compression chamber (57) formed by the front surfaces of both clamping ring elements may be put under pressure by a hydraulic fluid, causing the clamping ring elements to slid outwards on the V-shaped tapered ring sections. The ring-shaped compression chamber (57) is sealed in itself by sealing rings (55a, 55b; 63) that engage the clamping ring elements (53a, 53b) in all positions of the latter. The ring-shaped compression chamber (57) is thus hermetically sealed and hydraulic fluid cannot escape outwards.
