Cutting Head Depth Stop with Positioning Face for Precise Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delimitation devices for cutting heads face challenges in precisely positioning the cutting head relative to the detent sleeve with minimal effort, leading to inefficiencies in positioning and potential inaccuracies during repeated assemblies.
Innovation Solution
The delimitation device incorporates a sleeve holder with a positioning face that is fixed axially relative to the detent sleeve, allowing the cutting head to contact and rotate with it, ensuring precise positioning by maintaining the cutting head's axial position through a force-fitting or form-fitting mechanism, and utilizing a drive shaft element with a threaded portion for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional delimitation device without a positioning face is used, then the structure is simpler, but the cutting head cannot be precisely positioned relative to the detent sleeve during assembly
Solution Approach 1:
The positioning face acts as an intermediary element between the cutting head and the detent sleeve, providing a precise reference surface that enables accurate positioning without complex adjustment mechanisms. This single geometric feature mediates the positioning relationship, eliminating the need for repeated measurements or complex alignment procedures.
2Stability of the object's composition
If the cutting head position is not fixed axially, then the structure allows more flexibility, but the cutting position varies during repeated assemblies
Solution Approach 1:
The positioning face is pre-configured on the delimitation device with a specific axial position relative to the detent sleeve. This preliminary positioning action ensures that when the cutting head is assembled against the positioning face, the cutting position is automatically established with high precision, eliminating the need for post-assembly adjustments or repeated measurements.
3Manufacturing precision
If the positioning face is not disposed transversely to the rotation axis, then the structure is simpler, but the positioning precision is reduced and dependent on rotary position
Solution Approach 1:
The positioning face is disposed transversely (perpendicularly) to the rotation axis, creating an asymmetric orientation that provides unique positioning advantages. This transverse disposition ensures that the cutting head position is fixed in the axial direction regardless of the rotary position, eliminating positioning errors that would occur with angled or parallel orientations.

AI summary
A delimitation device delimits a penetration depth of a cutting head into a workpiece. The delimitation device has a detent sleeve, a sleeve holder and a cutting head. The detent sleeve has a detent side for landing on a workpiece surface. The sleeve holder in relation to a rotation axis is mounted so as to be rotatable relative to the detent sleeve, and in relation to the rotation axis is fixed in an axial position relative to the detent sleeve and supports the detent sleeve. The cutting head during a rotation of the cutting head conjointly rotates with the sleeve holder in relation to the rotation axis and has at least one cutting edge. The sleeve holder has a positioning face, wherein the positioning face is disposed proximal to the detent side, transversely to the rotation axis. The cutting head contacts the positioning face.
