Table-Mounted Wiper for Machine Tool Telescopic Cover Chip Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tools face issues with chip deposition on telescopic covers, particularly at the rear of the table, leading to increased sliding resistance and wear, which affects machine accuracy and chip removal efficiency.
Innovation Solution
A machine tool design featuring a wiper attached to the table's side surface that removes chips from both front and rear telescopic covers during table movement, utilizing cutting fluid channels to assist in chip discharge and minimize sliding resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a wiper is fixed to the telescopic cover to remove chips during table movement, then chip removal capability is improved, but sliding resistance between the telescopic cover and wiper increases, affecting machine accuracy
Solution Approach 1:
The patent introduces a wiper as an intermediary element that is fixed to the table rather than the telescopic cover. This wiper acts as a mediator to remove chips from the telescopic cover surface during table movement, eliminating the direct sliding contact between the cover and wiper that would generate resistance and affect accuracy.
Solution Approach 2:
Instead of fixing the wiper to the telescopic cover (conventional approach), the patent inverts the arrangement by fixing the wiper to the table. This inversion changes the reference frame of the wiper, allowing it to effectively clean the cover without creating sliding resistance that would compromise machine accuracy.
2Device complexity
If chip removal is performed only during door opening and closing, then device complexity is reduced, but chip deposition continues during prolonged idle periods, adversely affecting cover action
Solution Approach 1:
The patent enables continuous chip removal action by fixing the wiper to the table, which moves continuously during machining operations. This ensures that chips are removed continuously as the table moves, rather than only during intermittent door operations, maintaining reliable cover action throughout extended idle periods.
Solution Approach 2:
The wiper system operates automatically during table movement without requiring separate door operation actions. The table's own movement during normal operation drives the wiper to perform chip removal, making the system self-servicing and eliminating the need for additional complex control mechanisms.
3Object-generated harmful factors
If conventional chip removal methods are used, then front cover chip removal is addressed, but no solution is provided for chip deposition on the rear telescopic cover
Solution Approach 1:
The patent segments the chip removal function by providing multiple wipers positioned at different locations on the table. This segmentation allows each wiper to address specific zones (front and rear covers), expanding the overall coverage and adaptability of the chip removal system to handle chips deposited on both front and rear telescopic covers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively reduces sliding resistance and wear, ensuring reliable and efficient chip removal from both front and rear covers, maintaining machine accuracy and preventing chip interference.
Implementation Method 1
the sliding resistance between the telescopic cover and the wiper when the table moves
Implementation Method 2
a cutting fluid feeding channel which feeds a cutting fluid on the surface of the movable cover

AI summary
The machine tool includes a saddle, a table which moves relative to the saddle, a telescopic cover fixed to the saddle, and a wiper fixed to the table. The telescopic cover protects a guide member which supports the saddle in such a manner as to be capable of moving with respect to the bed. When chips generated by the working of a workpiece placed on the table have deposited on the surface of the telescopic cover, the wiper fixed to the table removes the chips by the movement of the table and causes the chips to fall.
