Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional read/write device is used in a turret-type automatic tool changer, then the device structure is simple, but the read/write head interferes with the tool holding structure and cannot be correctly positioned
Solution Approach 1:
The read/write head is made movable relative to the turret through a linear movement mechanism, allowing it to dynamically adjust its position to avoid interference with the tool holding structure while maintaining correct positioning for data reading/writing operations
Solution Approach 2:
The read/write device is divided into separate functional modules: a movable read/write head section, a base section, and a linear movement mechanism. This segmentation allows independent optimization of each component's function and position
2Measurement precision
If the read/write head is positioned close to the tool holder for accurate data reading, then measurement precision is improved, but machining dust adheres to the read/write head and hinders data reading
Solution Approach 1:
The read/write head is extracted from the main turret structure and positioned on a movable arm, separating it from the dust-prone tool holding area while maintaining close proximity for accurate data reading when needed
Solution Approach 2:
The read/write head can dynamically move between a retracted position (away from dust) and an extended position (close for reading), allowing it to avoid dust contamination during machining while maintaining positioning accuracy during data operations
3Ease of operation
If the read/write head is retracted to avoid interference, then ease of operation is improved, but positioning precision deteriorates
Solution Approach 1:
The linear movement mechanism enables the read/write head to dynamically transition between retracted and extended positions, allowing it to avoid interference when not in use while achieving precise positioning when data reading/writing is required
Solution Approach 2:
The control section receives signals about the turret's rotational position and controls the linear movement mechanism to position the read/write head at the correct location, ensuring accurate positioning through feedback-based control

AI summary
A tool information read/write device capable of being used in an automatic tool changer to which a conventional tool information read/write device cannot be applied, and a machine tool having the tool information read/write device. The read/write device has an arm section attached to a turret support part; a base section attached to the arm section; a slide section arranged on the base section so as to be linearly moved; a read/write head section attached to the slide section and configured to read/write information to a data carrier of a tool held by the turret; a drive section which drives the slide section so that the slide section reciprocates between a read/write position and an evacuation position; and a control section which controls the drive section in conjunction with a motion of the automatic tool changer.
