Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for machining sliding sleeves, particularly metallic ones, face challenges in achieving cost-effectiveness and dimensional accuracy due to mechanical deformation risks during rotational movements and limitations in designing complex surface reliefs on internal toothing.
Innovation Solution
A tool with a translational movement mechanism, featuring a transmission element and a shaped element with radially variable extension, allows for efficient machining of sliding sleeves by forming surface reliefs on internal teeth with precise control and reduced wear, enabling the creation of desired geometries such as latching grooves and stop teeth in a single step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rolling tool is used with rotational movements along the surface of the workpiece, then shaping can be achieved, but the workpiece may be mechanically deformed
Solution Approach 1:
Instead of rotating the tool along the workpiece surface (conventional rolling), the patent inverts the approach by using a translatory movement where the tool moves linearly along the internal toothing while the workpiece rotates. This inversion eliminates the risk of mechanical deformation while achieving the desired shaping of deposits on the tooth flanks.
Solution Approach 2:
The patent introduces a translatory movement mechanism as an intermediary between the driving device and the tool element. This intermediary movement system allows for controlled linear progression of the tool along the workpiece surface, preventing direct rotational contact that could cause deformation while still enabling effective shaping.
2Adaptability or versatility
If multiple processing steps are used to create different surface reliefs (backings, locking grooves, stop teeth), then complex geometries can be achieved, but processing time and costs increase
Solution Approach 1:
The patent merges multiple shaping functions into a single tool element with a form relief that can create different surface reliefs (backings, locking grooves, stop teeth) in one continuous translatory movement. This combining of functions eliminates the need for multiple separate processing steps, thereby maintaining design versatility while significantly improving productivity and reducing costs.
Solution Approach 2:
The tool element is designed with universal capability to form various types of surface reliefs through its form relief geometry. By making the tool multi-functional, a single processing pass can produce complex geometries that previously required multiple specialized operations, thus enhancing both adaptability and productivity.
3Device complexity
If the drive element acts directly on the tool element, then simple power transmission is achieved, but wear of the tool element increases and adjustment precision decreases
Solution Approach 1:
The patent introduces the translatory movement mechanism as an intermediary between the drive element and the tool element. This intermediary system provides finer power transmission control, enabling more precise adjustment of the form relief engagement with the workpiece surface, thereby improving manufacturing precision while distributing wear away from the tool element.

AI summary
The invention relates to a tool (1) for machining a workpiece (4). The tool (1) contains a tool element (3) that can be moved in the working direction (22) in order to be applied to a surface (21) of the workpiece (4). A drive element (19, 19a, 19b) that can be driven in a drive direction (24) transversally to the working direction (22) of the tool element (3) interacts with the tool element (3) to transmit a force. A transmission element (2, 2a, 2b) for transmitting force between the drive element (19, 19a, 19b) and the tool element (3) is positioned between the tool element (3) and the drive element (19, 19a, 19b).
