Tool Holding Frame Bidirectional Positioning Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool holding frames fail to provide a sufficient positioning effect in dual-movement directions and rotation, leading to easy movement of positioning mounts relative to the track base when a force is applied.
Innovation Solution
A tool holding frame design featuring an elongated track base with sliding channels, a resilient positioning board with curved positioning blocks and recesses, and positioning mounts with annular positioning flanges and teeth, allowing for firm positioning in both movement directions and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If curved grooves are used for positioning, then positioning effect in one movement direction is provided, but positioning effect in dual-movement directions cannot be achieved
Solution Approach 1:
The patent transitions from unidirectional curved groove positioning to bidirectional positioning by adding a second set of positioning features (positioning ribs and positioning grooves) that operate in a perpendicular dimension, enabling positioning in both movement directions simultaneously
Solution Approach 2:
The positioning system is segmented into multiple independent positioning elements: positioning blocks with curved grooves for one direction, and positioning ribs with positioning grooves for the other direction, allowing each segment to handle specific directional positioning requirements
2Manufacturing precision
If conventional engaging segments are used, then rotation positioning is provided, but movement positioning effect is insufficient
Solution Approach 1:
The patent merges rotation positioning features (teeth and curved grooves) with movement positioning features (positioning ribs and positioning grooves) into a unified positioning system, allowing both rotational and linear positioning functions to coexist and work together for comprehensive positioning stability
3Ease of operation
If positioning mounts are made movable for easy adjustment, then ease of operation is improved, but positioning stability under external force deteriorates
Solution Approach 1:
The positioning system employs dynamic positioning where positioning blocks can be easily inserted and removed from positioning grooves for adjustment, but once positioned, the engagement between positioning ribs and grooves provides stable resistance against external forces, achieving both ease of operation and positioning reliability

AI summary
A tool holding frame has a track base, a positioning board, and at least one positioning mount. The positioning board is disposed on the track base and has a positioning segment. The first positioning segment has multiple positioning blocks having curved side edges and multiple positioning portions. The at least one positioning mount is slidably and rotatably mounted on the track base. Each positioning mount has an annular positioning flange and a second positioning segment. The second positioning segment is selectively engaged with two of the positioning portions.
