Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing calibration master installation methods for machine tools are costly, cumbersome, and can alter the accuracy of the calibration master, and they require additional machining or a table slot, making them inconvenient and inaccurate.
Innovation Solution
A calibration master installing jig composed of a plate with holes and rod materials that can be inserted into slots or tap holes on a machine tool table, allowing the calibration master to be easily aligned in a predetermined direction without altering its accuracy, using a lightweight and inexpensive setup that does not require additional machining or a table slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guide blocks are used to install the calibration master, then the calibration master can be installed in a predetermined direction, but additional machining (tap holes and guide groove) is required which changes the accuracy of the calibration master
Solution Approach 1:
The patent introduces a mounting plate as an intermediary component between the calibration master and the table. The mounting plate has through-holes that accommodate rod materials, which are inserted into tap holes on the table. This intermediary structure enables installation without requiring guide grooves or additional machining on the calibration master itself, thus preserving its accuracy while still providing predetermined direction installation capability.
Solution Approach 2:
The patent divides the installation system into separate functional components: the calibration master remains unchanged, the table provides tap holes, and a separate mounting plate with rod materials handles the alignment and installation. This segmentation allows each component to perform its specific function without compromising the calibration master's accuracy.
2Adaptability or versatility
If guide blocks are disposed on the bottom surface of the calibration master, then installation in predetermined direction is enabled, but the calibration master requires additional machining which alters its accuracy
Solution Approach 1:
The mounting plate serves as an intermediary that provides the adaptability for installation in predetermined directions without requiring modifications to the calibration master. The rod materials inserted through the mounting plate's holes engage with tap holes on the table, enabling versatile installation options while keeping the calibration master unchanged.
3Measurement precision
If a complex mechanism gauge is used, then motion errors can be measured, but the manufacturing cost increases
Solution Approach 1:
The patent replaces complex, expensive gauge mechanisms with simple, inexpensive components: a mounting plate with holes and rod materials. These simple components enable the same measurement functionality without the need for complex mechanical mechanisms, significantly reducing manufacturing cost while maintaining measurement precision.
4Measurement precision
If a weighty gauge is used, then motion errors can be measured, but it becomes inconvenient to install and carry
Solution Approach 1:
The patent replaces heavy gauge mechanisms with lightweight components: a thin mounting plate and slender rod materials. This substitution dramatically reduces the weight of the installation system while maintaining the ability to measure motion errors, making it convenient to install and transport.

AI summary
A calibration master installing jig for installing a calibration master in a predetermined direction on a table when the calibration master installed in the predetermined direction on the table is measured using a sensor mounted to a spindle head in a machine tool. The machine tool includes two or more translational axes and the table provided with a plurality of slots or tap holes. The calibration master installing jig includes a plate and a plurality of rod materials. A plurality of holes are provided in the plate. The plurality of rod materials are insertable into the holes. By putting the plurality of rod materials individually inserted into any given plurality of the holes into any of the slots or the tap holes, any given side surface of the plate or a straight line connecting the plurality of rod materials becomes parallel to the predetermined direction on the table.
