Embodiment Construction

[0030]The connecting means shown in the figures are used for the detachable coupling of the components 10 , 12 . In the following, “component” is understood primarily to mean the part of the tool that contains a cooperating pin 14 or a receiving sleeve 16 . In the embodiment shown in FIG. 1, the component 10 equipped with the cooperating pin 14 is a measuring mandrel, and the component 12 provided with the receiving sleeve 16 is an adapter, which has a coupling for connection to the spindle of the machine tool. Steeply tapered shaft 18 .

[0031] The connecting device mainly includes a mating pin 14 protruding axially on the first member 10; a receiving sleeve 16 arranged on the second member; 14 is drawn into the receiving sleeve 16 and serves to clamp in a plane between an annular plane 22 of the first component 10 delimiting the cooperating pin 14 and an end face 24 of the second component 12 delimiting the receiving sleeve 16 . The counter pin 14 has a substantially cyli...

Abstract

The invention relates to a device for coupling two parts (10, 12), for example two tool parts. The first part (10) comprises a cylindrical adapting journal (14) and a radial flat surface (22) which limits the adapting journal by the base (28) thereof and is radially protruded, whereas the second part (12) is provided with a receiving sleeve (16) with the cylindrical internal surface (32). The invention also relates to a clamping device (20) which, during clamping, enables the adapting journal (14) to be inserted into the receiving sleeve (16) and to be pressed thereto between the flat surface(22) and a front surface (24).; In order to guarantee an exact centring of the parts with the aid of simple means, the inventive receiving sleeve is provided with a lower conical part (34) diverging from the internal cylindrical surface towards the front surface and the adapting journal is provided with an elastically deformable centring ring (29) which is arranged at the level of the base and isprovided with an external conical part complementary to the lower conical part (34).

Description

technical field [0001] The invention relates to a device for the coupling of two components, in particular two tool parts, having a cooperating pin arranged on a first component having a substantially cylindrical outer surface and a cooperating pin on the coordinating pin The root delimits the radially protruding annular plane of the cooperating pin, has a receiving sleeve arranged on the second member, has a cylindrical inner surface and is bounded by an annular end surface, and has a mating Clamping mechanism in which the pin is drawn into the receiving sleeve and at this time presses the flat surface and the end face against each other, wherein the receiving sleeve has an inner conical portion that expands from the cylindrical inner surface towards the end face, and the mating pin has an inner The cone portion is complementary to the outer cone portion. Background technique [0002] The coupling device according to the invention is primarily intended for the detachable c...
