Centering Accessory for Rotating Guide Bush Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current centering methods for machining tools on rotating guide bushes require manual precision and experience, limiting their use to trained operators and often result in tool offset errors that lead to defects and premature tool breakage in high-precision industries.
Innovation Solution
A centering accessory with a straight body and rotating head, featuring reversible connecting means and a positioning member for a measuring probe, simplifies the alignment of the tool with the rotation axis, allowing for precise positioning and automatic adjustment using an electronic measuring device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual centering methods are used with measuring probes, then centering precision can be achieved, but operator experience and manual precision are required, limiting use to trained operators only
Solution Approach 1:
A laser alignment device is introduced as an intermediary tool between the operator and the centering task. The device projects reference lines and provides visual feedback, mediating the alignment process so that operators do not need extensive training to achieve precise centering. The laser device acts as a mediator that translates complex measurement tasks into simple visual alignment tasks.
Solution Approach 2:
The patent replaces manual mechanical measurement methods with an optical laser-based system. Instead of relying on operators to manually position and measure with physical probes, the system uses laser projection and optical alignment, substituting mechanical operations with optical fields that provide automatic visual guidance for precise centering.
2Ease of operation
If manual centering methods are used, then centering can be performed, but tool offset errors occur leading to defects and premature tool breakage
Solution Approach 1:
The laser alignment device provides continuous visual feedback through projected reference lines that show the alignment status in real-time. This feedback mechanism allows operators to immediately see and correct any offset errors, preventing defective machining before it occurs. The system monitors and communicates alignment quality continuously during the centering process.
Solution Approach 2:
The system performs preliminary alignment verification using laser projection before actual machining begins. By establishing accurate reference lines and confirming proper centering in advance, the system prevents tool offset errors from occurring during the machining process itself, thereby preventing defects and tool breakage before they happen.
3Measurement precision
If traditional centering devices are used, then centering can be achieved, but the process is time-consuming and requires complex manual positioning
Solution Approach 1:
The patent replaces time-consuming manual mechanical positioning with rapid optical laser projection. The laser device instantly establishes reference lines without requiring gradual manual adjustment, dramatically reducing the time needed to achieve precise alignment while maintaining high positioning accuracy through optical rather than mechanical means.
