摘要:
Pressing device for the relative axial displacement of two mutually coaxial parts that can only be displaced towards one another by using a high pressing power, for example collet chucks or clamping sleeves, into corresponding holes in tool or collet chuck holders. The device has a housing (7) consisting of two at least partially separable shells, which can be placed coaxially around the parts to be pressed. In the closed state, the housing has coaxial annular contacting edges (19, 20) for engaging with one of the parts to be pressed. In the inner chamber (21) of the housing there is an axially displaceable pressing plate (22) with an annular contacting edge (23) for engaging with the second part to be pressed. The press plate is displaced by a number of pressure cylinders (13, 14) arranged in a ring at equal angular distances between the housing and the press plate.

A spring fixture (1) is provided for quickly installing or uninstalling a coil spring (36) in or from an electrical connector (3). The fixture includes an operation member (11) having a generally cylindrical handle (12) at an end thereof and an action member (16) assembled on an opposite end of the operation member by a screw cap (18). The action member defines a recess (1620) thereby forming a semi-circular bottom wall (1622) and a semi-circular inner wall (1624). During installing or removing the spring, the spring is received in the recess and surrounded by the inner wall. A method of using the fixture to install and remove the spring is also provided.

Apparatus for use in repairing, and methods of repairing, a door hinge of a vehicle includes use of a substitute hinge bracket and at least one pin configured to be received through at least one opening of a vehicle frame bracket. A locking portion of the at least one pin and a locking surface that defines an opening in the hinge bracket are configured such that the at least one pin is locked in a fixed position relative to the hinge bracket when assembled. Further, another repair apparatus includes a substitute pin having an interference portion for forming an interference fit with one or more surfaces defining an opening of a factory hinge bracket.

A method is provided for securing a branch assembly (1) to a nulllivenull pipeline (6). An upper part (2) of the assembly incorporating the branch (13) is positioned on the pipeline over a first containment ring/annular seal arrangement (16/17) and a second containment ring/annular seal arrangement (116/117) spaced from the first arrangement to leave an annular gap (118) therebetween. A lower part 3 of the assembly is positioned on the pipeline beneath the upper part and the two parts are secured together so that the seals are compressed. An access point (119) allows the monitoring of the pressure in the annular gap (118) to check for seal integrity of the inner seal (17). If pressure is detected, as a result of leakage of fluid via the branch (13) past the seal (17) the vent can be closed so that the second seal (117) becomes effective.

A removal and installation device for external and internal snap rings that can switch to a shaft mode and a hole mode by extremely simple operation and produces more excellent effect in controllability, workability, serviceability and easiness in handling is provided. When a rotary plate 12 is rotated in a positive direction, a left side lever 3 is turned as a shaft part 13 is eccentrically rotated integrally with the rotary plate 12, right and left side levers 2, 3 are crossed substantially in an X shape, the crossed parts are supported by the shaft part 13 and the hole mode is realized. When the rotary plate 12 is rotated in a reverse direction, the left side lever is turned in a reverse direction as the shaft part 13 is eccentrically rotated in a reverse direction integrally with the rotary plate 12, both pivot parts 2c, 3c of the right and left side levers 2, 3 arranged substantially in a V shape are supported by the shaft part 13 so that both projected working tools 4a, 5a are parallel and the shaft mode is realized.

A tool for replacing brake pads of disc braking systems of automobiles includes a screw rod combined with a sliding handle and having a ring groove; a first plate body combined with the screw rod and having two through holes; a second plate body screwed with the screw rod and having a screw hole and a through hole respectively aligned with the through holes of the first plate body; a guide rod extending through the through holes of the second plate body and the first plate body and having two ring grooves at both ends. The ring grooves can be engaged with retainer rings. Only to place the first plate body and the second plate body against front ends of more than one piston and to rotate the screw rod forward, a user can press the pistons to their initial positions simultaneously at a time for replacing new brake pads.

An extractor is provided for extracting a pin or another component which is pressed into a hole and protrudes from the hole with a cylindrical section. The extractor has a gripping element, which has a tubular basic body, is axially adjustable in a guide tube and is provided at its outer ends with at least two gripping jaws having conical outer jacket surfaces. With the gripping jaws the gripping element can be attached to the center pin or the cylindrical section. The basic body can be pulled axially into the guide tube, as a result of which the gripping jaws are pressed by conical jacket surfaces radially inwardly in cooperation with the guide tube, so that a snug hold of the gripping jaws at the cylindrical pin or the cylindrical section is brought about. Provisions are made according to the present invention that to make handling as simple as possible, the extractor has an extractor with a support tube, which can be pushed over the guide tube and is axially adjustable in relation to the guide tube via a mechanical adjusting drive, and that the support tube is supported axially indirectly or directly in the area surrounding the straight pin during the axial adjustment.
