Tool Positioning Mechanism with Elastic Pivot for Precision Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool handling mechanisms during machining processes lack efficient and reliable methods for positioning and holding tools, particularly in ensuring secure attachment and easy detachment, which can lead to tool misalignment and reduced precision.
Innovation Solution
A tool positioning and holding mechanism comprising a mounting frame, a feed member, a tool support, a positioning member, an elastic member, and a blocking member, where the feed member is slidably mounted on the frame, allowing the positioning member to pivot and rotate under elastic force to securely position and hold the tool, facilitating easy detachment and repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional tool holding mechanism is used, then the structure is simple, but the tool positioning precision and secure attachment are insufficient
Solution Approach 1:
The positioning member is designed to rotate between a locked position (engaging with the blocking member) and an unlocked position, transforming a static holding mechanism into a dynamic one that provides both secure attachment and easy release. This rotational movement enables precise tool positioning while maintaining structural simplicity.
Solution Approach 2:
The elastic member acts as an intermediary that stores and releases mechanical energy to drive the positioning member between locked and unlocked states. This intermediary component enables the tool to be securely held during machining while allowing quick release when needed, resolving the contradiction between secure attachment and easy detachment.
2Reliability
If a secure tool attachment mechanism is implemented, then tool holding reliability improves, but tool detachment becomes difficult
Solution Approach 1:
The blocking member is pre-positioned to engage with the positioning member, creating a preliminary locking action that secures the tool during machining. When detachment is needed, the feed member moves to disengage the blocking member, allowing the elastic member to automatically rotate the positioning member to the unlocked state. This preliminary locking followed by automatic release resolves the contradiction between secure holding and easy detachment.
Solution Approach 2:
The elastic member stores potential energy when the positioning member is in the locked position and automatically releases this energy to rotate the positioning member to the unlocked position when the blocking member is disengaged. This self-service mechanism eliminates the need for additional actuators or complex release mechanisms, enabling both reliable holding and easy tool detachment.
3Manufacturing precision
If tool positioning precision is enhanced, then machining accuracy improves, but the time for tool attachment and adjustment increases
Solution Approach 1:
The positioning member is pre-configured with engagement features that automatically align with the blocking member when the tool is inserted. The elastic member is pre-loaded to provide immediate locking action, eliminating the need for manual adjustment or alignment procedures. This preliminary configuration enables both high positioning precision and rapid tool attachment.
Solution Approach 2:
The mechanism uses the feed member's movement to automatically disengage the blocking member, which then allows the elastic member to self-actuate the positioning member into the correct position. This self-service operation eliminates manual intervention for tool positioning, achieving both high precision and quick tool changes.

AI summary
A tool positioning and holding mechanism includes a mounting frame, a feed member, a tool support, a positioning member, an elastic member, and a blocking member. The feed member is slidably mounted on the mounting frame. The tool support is fixed on the feed member and defines a receiving hole to receive the tool. The positioning member is pivotally coupled to the tool support and partially received in the tool support. The elastic member is located between the positioning member and the tool support. The blocking member is fixed on the mounting frame and includes a pushing portion configured to resist the positioning member. The feed member can move the positioning member to allow detachment of the positioning member from the pushing portion, and upon detachment of the positioning member, the positioning member is configured to rotate under an elastic force of the elastic member to position the tool.
