Embodiment Construction

[0045] Figure 1a A plan view along the axial direction on the clamping sleeve 1 according to the invention is shown. The axis is for example Figure 4 Shown in and marked with R. The clamping sleeve 1 has a supporting surface 2 and an opposite supporting surface formed by a sliding block 3. The sliding block 3 has a groove 11 and the opposite bearing surface 2 has a groove 9 so as to obtain a fork-shaped area 10 for receiving the member 7 as a whole. The fork shaft is marked with A. In the figure shown, the member 7 is represented by a cam. But other components, such as sensor wheels, are also possible. The member 7 has a cylindrical receiving hole 12 and a protrusion 19 extending radially outward from the axial direction. The supporting surface 2 and the opposite supporting surface formed by the slider 3 fix the axial position of the member 7 in two axial directions in a form-fitting manner. The slider 3 can move between the clamping position and the receiving position in...

Abstract

The invention relates to a clamping sleeve (1) for positioning and mounting a component (7) on a shaft (16). The component (16) thus comprises a central part (20) with a cylindrical receiving hole (12) for receiving the shaft (16). The clamping sleeve (1) has a fork-shaped area (10) for receiving a component (7), wherein the fork-shaped area (10) comprises a plurality of clamping parts (4, 5), which fix the component (7) Angular position inside the forked region (10). Furthermore, the fork-shaped region (10) comprises two opposing bearing surfaces (2, 2b), which positively fix the axial position of the component (7) in both axial directions.

Description

Background technique [0001] In the production of camshafts, the different components are manufactured separately and assembled on the prefabricated shaft. For assembly, these components are moved axially on the shaft to the expansion part of the shaft. This is usually carried out by means of a tool called a clamping sleeve. Tools of this type are known from DE 102009060349 A1. A tool called an alignment unit is used to clamp and move the component along the shaft (that is, in the axial direction). The alignment unit additionally has different components, which are used to adjust the angular position of the component. The illustrated alignment unit has only one collet in the axial direction, and the collet is used to fix the component in the axial direction in a form-fitting manner. Therefore, the component can only be moved in the axial direction by means of the alignment unit. After the component is fixed, the alignment unit moves in the opposite axial direction until the ...
