Detachable External Robot Stand for Machine Tool Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot stands mounted on machine tools are difficult to access for maintenance due to their fixed and integrated design, requiring complete removal from the machine tool, which complicates maintenance and increases man-hours.
Innovation Solution
A detachable external robot stand comprising a fixed unit and a movable unit, with a robot installation surface and safety fences surrounding the operating range, allowing easy access for maintenance by separating the movable unit, thus enabling independent relocation and calibration without reprogramming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot stand is fixed and integrated to the machine tool, then the robot maintains stable positioning and operating range, but maintenance access becomes difficult and requires complete removal of the stand
Solution Approach 1:
The robot stand is divided into multiple detachable sections: a fixed base unit attached to the machine tool and a movable unit that can be separated. This segmentation allows the movable unit to be removed for maintenance while the fixed base remains in place, resolving the contradiction between stable positioning and maintenance accessibility.
2Ease of repair
If the robot stand is made completely detachable for easy maintenance, then maintenance access improves, but the robot's positioned state and calibration are lost requiring reprogramming
Solution Approach 1:
The fixed base unit maintains the robot's positioned state and calibration information even when the movable unit is detached. This preliminary establishment of a stable reference frame allows the robot to be quickly reattached and resumed without full repositioning or reprogramming, reducing time loss during maintenance.
3Reliability
If safety fences surround the entire robot stand, then robot operating range is protected, but access to the inside of the stand becomes blocked
Solution Approach 1:
The safety fencing is divided into fixed portions attached to the machine tool and movable portions attached to the movable unit. When the movable unit is detached for maintenance, the movable safety fence portions are removed, providing access while the fixed safety fences remain in place to maintain protection of the robot's operating range.

AI summary
An external robot stand that is installed outside a machine tool includes a fixed unit fixed to the machine tool in a positioned state and a movable unit attached to the fixed unit in a detachable manner. The fixed unit is provided with a robot installation surface on which a robot that performs work with respect to the machine tool can be installed. An operating range of the robot is arranged to extend across both of the fixed unit and the movable unit. The fixed unit and the movable unit are respectively provided with safety fences that surround an outer side of the operating range of the robot together with the machine tool in a state in which the movable unit is attached to the fixed unit.
