Embodiment Construction

[0026] Figure 1 shows the main parts of a compacting device according to the invention, details such as hinges, enclosures, hydraulic lines, etc. being omitted from this figure for the sake of clarity. The outer casing 1 consists of two half-shells 2 rotatable relative to each other about a connecting axis and in each case of an upper part 3 and a base part 4 to which said upper part 4 is rigidly connected. Each half shell has a recess 5 into which a lower fixing plate 6 , an upper fixing plate 7 and a pressure plate 8 are inserted and the pressure plate is movable between the two fixing plates. The two inserts entering into the half-shells together form an interchangeable jaw arrangement which completely encloses an inserted tool or workpiece when the two half-shells of the housing are closed. Therefore, in the following description, an insert in a half-shell is called a half-insert.

[0027] As shown in FIG. 2 , the recess 5 has a semi-cylindrical shape, as can be seen from...

Abstract

Pressing device for the relative axial movement of two parts, which are arranged coaxially with respect to one another and are moveable relative to one another only by means of a high pressing power, such as for example collet chucks or sleeves, into corresponding bores of tool or collet chuck holders. The device has an outer housing which coaxially surrounds the parts which are to be pressed and which can be swung open along an axial plane. Half-inserts can be inserted into said outer housing, which half-inserts comprise in each case two fixed plates with engagement edges for the engagement on one of the parts which are to be pressed, and an axially moveable pressure plate with an engagement edge for the engagement on the second part which is to be pressed.

Description

technical field [0001] The invention relates to a pressing device for the relative axial displacement of two parts which are arranged coaxially relative to each other and which can be moved relative to each other only by high pressing forces, said pressing device There is a housing which coaxially surrounds the two parts to be compressed and which in the closed state comprises: at least one coaxial annular engagement edge for engaging in one of the two parts to be compressed on one part; a pressure plate axially movable inside the housing and having a coaxial annular engagement edge for engaging on the other of the two parts to be compressed; and a plurality of annular arrangements The pressure cylinders are arranged at uniform angular intervals between the housing and the pressure plate. [0002] A compression process of the described type is used, for example, for the compression of pipe ends or shaft connections. Since the friction of the tight fit has to be overcome and ...
