Telescopic Cover Linkage for Machine Tool Contaminant Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic covering devices for machine tools are inadequate in allowing the smallest cover member to be moved or adjusted relative to the saddle or machine base, failing to effectively shield or protect the sliding engagements from cut chips and contaminants.
Innovation Solution
A telescopic covering device with a movable linking mechanism, comprising a first cover member attached to the table, a second cover member coupled to the carrier, and intermediate cover members that telescopically slide relative to each other, along with a connecting device and spring biasing system to facilitate smooth adjustment and protection from contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the smallest cover member is solidly secured to the stationary saddle, then the covering device is simple and stable, but it cannot be adjusted or moved to suitably cover the sliding engagements
Solution Approach 1:
The patent applies the dynamics principle by transforming the static connection between the cover member and saddle into a dynamic telescopic connection. The rod can slide within the tubular member, allowing the cover member to move relative to the saddle while maintaining connection. This enables the cover member to adapt to different positions of the sliding engagement while keeping the overall structure relatively simple.
2Adaptability or versatility
If the smallest cover member is made movable relative to the saddle, then it can adjust to cover different sliding engagements, but the linking mechanism becomes more complex
Solution Approach 1:
The patent applies the nested doll principle through the telescopic structure where the rod is nested within the tubular member. This allows one component to be contained within another, enabling the cover member to extend and retract while maintaining a compact form when not in use. This nesting approach increases coverage range without proportionally increasing overall device complexity.
3Ease of operation
If the cover members are telescopically movable, then they can follow the sliding movement of the table, but the connection between cover members and saddle becomes more complex
Solution Approach 1:
The patent applies the intermediary principle by introducing a spring as a mediator between the rod and tubular member. The spring provides automatic biasing force that maintains engagement between the telescopic components while allowing smooth relative movement. This intermediary element simplifies the overall connection by providing self-adjusting force without requiring complex control mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the smallest cover member to be smoothly slid or adjusted relative to the saddle or machine base, effectively preventing contaminants from entering the sliding engagement area and maintaining clean operation of machine tools.
Implementation Method 1
a spring biasing device for biasing the table to move or to be recovered relative to the carrier in order to force the tubular member to engage onto the rod

AI summary
A machine tool includes a table slidably supported on a carrier and movable relative to the carrier by a driving device, a telescopic covering device having two or more cover members telescopically slide relative to each other in response to a sliding movement between the table and the carrier. A connecting device includes a tubular member attached to the inner cover member, and a rod attached to the carrier and movable into and out of the tubular member when the inner cover member is moved relative to the carrier for guiding the table to smoothly slide relative to the carrier.
