Insert Plate Leveling Structure for Wear and Warp Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support table systems for powered hand tools, such as routers, face challenges in precisely positioning insert plates relative to the support table, especially when the insert plates wear or warp over time, leading to misalignment and potential workpiece catching issues.
Innovation Solution
A mounting and leveling apparatus comprising a clamp screw, at least two leveling screws, and a mounting bracket that allows independent adjustment of the insert plate's position relative to the support table, ensuring precise alignment and secure mounting, even when the insert plate becomes worn or warped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insert plate is rigidly fixed to the support table, then the mounting structure is simple and stable, but the insert plate cannot be adjusted to correct wear and warp, leading to misalignment
Solution Approach 1:
The mounting apparatus transforms a rigid fixed connection into a dynamic adjustable system. The leveling screws enable the insert plate to be positioned at different heights and angles, allowing the system to adapt to wear and warp while maintaining stable operation when properly aligned.
Solution Approach 2:
The invention changes the mounting parameters from fixed to variable. By introducing adjustable leveling screws, the vertical position and angular orientation of the insert plate can be modified to compensate for wear and deformation, resolving the contradiction between stability and adaptability.
2Adaptability or versatility
If the insert plate is made adjustable to correct wear and warp, then adaptability improves, but the mounting structure becomes more complex
Solution Approach 1:
The mounting apparatus is segmented into distinct functional components: leveling screws for height adjustment, clamping mechanism for securing, and mounting brackets for positioning. This segmentation allows each component to perform its specific function independently, making the complex adjustment system manageable and maintainable.
Solution Approach 2:
The mounting apparatus integrates multiple functions into a single system: positioning, leveling, clamping, and securing. This multi-functionality reduces the need for separate adjustment mechanisms, thereby limiting the increase in device complexity while achieving the required adaptability.
3Measurement precision
If multiple leveling screws are used to achieve precise alignment, then alignment precision improves, but the mounting process requires more time and steps
Solution Approach 1:
The mounting bracket is pre-positioned on the support table before the insert plate is attached. This preliminary action establishes the correct horizontal position and orientation, so that subsequent leveling adjustments only require vertical height correction, reducing the total time needed for precise alignment.
Solution Approach 2:
The leveling screws provide dynamic adjustment capability that allows for fine-tuning the insert plate's vertical position. This dynamic adjustment is more efficient than rigid pre-drilled hole systems, as it allows for continuous positioning rather than discrete hole locations, achieving higher precision with fewer adjustment iterations.

AI summary
An assembly comprises a support table including a support table orifice; a insert plate within the support table orifice; and at least one mounting and leveling apparatus. The mounting and leveling apparatus comprises a clamp screw; at least two leveling screws; at least one mounting screw; and a mounting bracket that defines a first threaded hole that threadably engages the clamp screw, a second hole that receives the at least one mounting screw and a third set of threaded holes that each threadably engages one of the at least two leveling screws. The clamp screw pulls the insert plate towards the mounting bracket when tightened. The at least one mounting screw couples the mounting bracket to the support table. The at least two leveling screws are independently adjustable to allow a top surface of the insert plate to be precisely aligned with a top surface of the support table.
