Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional planer elevating devices can only adjust the worktable to a certain height, lacking precision and the ability to perform precise work-piece processing.
Innovation Solution
A quick elevating and micro-adjusting device comprising an adjusting block, micro-adjusting rod, threaded shaft, elevating rod, support shaft, and micro-adjustment locking member, allowing for both quick and precise adjustments of the movable worktable by engaging a worm with a worm gear to drive a threaded rod, enabling precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional elevating device is used to adjust the worktable height, then the worktable can be quickly moved to a certain height, but the adjustment precision is insufficient and cannot perform precise work-piece processing
Solution Approach 1:
The adjustment device is segmented into two independent subsystems: a quick-adjustment mechanism (elevating rod connected to support shaft) for rapid height changes, and a micro-adjustment mechanism (micro-adjusting rod with worm gear driving threaded shaft) for precise positioning. This segmentation allows each subsystem to optimize for its specific function without compromising the other.
Solution Approach 2:
The threaded shaft acts as an intermediary between the micro-adjusting rod and the holding frame. The worm gear engages with the threaded shaft to convert rotational motion into precise linear displacement, enabling fine control of the holding frame's position and thus the worktable's height with high precision.
2Productivity
If only quick adjustment function is provided, then the operation speed is fast, but the processing quality cannot be ensured due to lack of fine-tuning capability
Solution Approach 1:
The adjustment device provides dynamic adaptability by allowing the user to first use the elevating rod for rapid coarse adjustment to reach the approximate target height, then switch to the micro-adjusting rod for precise fine-tuning. This dynamic two-stage adjustment process optimizes both speed and precision throughout the adjustment sequence.
Solution Approach 2:
The device changes the adjustment parameter scale from macro (quick adjustment in larger increments via elevating rod) to micro (fine adjustment in smaller increments via micro-adjusting rod and threaded shaft). This parameter transition enables the system to achieve both rapid positioning and precise final placement of the worktable.

AI summary
A quick elevating and micro-adjusting device for the worktable of a manual planer includes a base, a stationary worktable, a movable worktable and an adjustment device. The adjustment device has its support shaft inserted in the fixing holes of two side plates of the movable worktable. The adjustment device has an elevating rod to be moved up or down for actuating the support shaft to quickly move the movable worktable upward or downward. A micro-adjusting rod has its worm engaged with the worm gear of a threaded shaft for rotating together to drive the threaded rod of the threaded shaft to rotate and move the holding frame of the threaded shaft, which is secured on the movable worktable. Thus, by turning the micro-adjusting rod, the movable worktable can be micro-adjusted in position. Thus the worktable can be adjusted quickly and precisely.
