Machine Tool Cover Stop Structure Reduces Door Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent opening and closing of machine tool slide doors lead to excessive wear and damage of shock absorbing members, resulting in increased shock transmission to electronic devices, such as CNCs and operation panels, due to the influence of chips and coolant.
Innovation Solution
A cover structure for machine tools incorporating a stop structure portion that prevents the slide door from colliding directly with the fixed cover, using a shock absorbing member attached to the slide door or fixed cover, which can be made of cushion rubber, sponge, or spring materials, to absorb shocks and reduce wear, and allowing for easy attachment and detachment for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shock absorbing member is attached to the closing-direction end surface of the slide door to reduce collision shock, then the shock to electronic devices is reduced, but the shock absorbing member suffers excessive wear and damage due to frequent opening and closing operations
Solution Approach 1:
The shock absorbing function is divided into two separate components: a stop structure portion that prevents excessive collision, and a shock absorbing member that provides cushioning. This segmentation allows each component to perform its specific function optimally, with the stop structure bearing the brunt of collision forces and the shock absorbing member providing supplementary protection, thereby reducing wear on the shock absorbing member.
Solution Approach 2:
The stop structure portion is positioned to engage with the fixed cover before the slide door fully closes, providing preliminary cushioning and preventing direct collision between the slide door and the fixed cover. This beforehand cushioning reduces the impact force that reaches the shock absorbing member, extending its service life while still protecting electronic devices.
2Productivity
If the slide door is opened and closed frequently to increase production efficiency, then productivity is improved, but the shock absorbing member wears out faster and transmits more shock to electronic devices
Solution Approach 1:
By segmenting the shock protection function into a stop structure portion and a shock absorbing member, the system can handle frequent operations more reliably. The stop structure provides consistent collision prevention that doesn't degrade with use, while the shock absorbing member provides supplementary protection, ensuring electronic devices remain protected even during high-frequency operation.
Solution Approach 2:
The stop structure portion engages in preliminary action by preventing excessive collision before it occurs, creating a more stable operating condition that reduces shock transmission to electronic devices during frequent opening and closing operations.
3Reliability
If cushion rubber or sponge is attached to the slide door to absorb shock, then collision shock is reduced, but the shock absorbing member is affected by chips and coolant causing accelerated deterioration
Solution Approach 1:
The stop structure portion is positioned to engage with the fixed cover at a location less exposed to chips and coolant, while the shock absorbing member provides supplementary protection. This segmentation allows the primary shock absorption function to be performed in a more protected location, reducing the harmful effects of chips and coolant on the shock absorbing materials.

AI summary
A cover structure of a machine tool, including a fixed cover for isolating the inside portion of the machine tool from the outside, the inside portion serving as a machining space, and a one-side opening type slide door for opening and closing an opening portion formed in the fixed cover, includes a stop structure portion for, when the slide door is closed, stopping the slide door at a predetermined distance away from the end surface of the opening portion of the fixed cover. The stop structure portion is provided on a portion of the slide door other than the closing-direction-side end surface of the slide door, or at a portion of the fixed cover other than the slide-door-closing-side end surface of the opening portion of the fixed cover.
