Lathe Misalignment Gauge Layout for Short Axial Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional misalignment determining devices for lathes are too large in the axial direction, making them unsuitable for applications where the distance between the tool holder mounting portion and the chuck is small.
Innovation Solution
A compact misalignment determining device design featuring a tubular case with a dial gauge, a rotatable holder portion, a pivotal portion, a lever member, and a slide member, where the pivot amount of the pivotal portion is transmitted to the lever member and then to the slide member, allowing the dial gauge to detect the pivot amount through the slide member's movement, reducing the axial size without increasing the radial size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the slider body is moved in the axial direction to transmit the pivot amount, then the pivot amount can be determined, but the size in the axial direction becomes large
Solution Approach 1:
The invention changes the transmission direction from axial to radial by having the lever member extend in the radial direction. The pivotal body pivots about a radial axis, and the lever member transmits the pivot amount radially to the dial gauge, avoiding axial extension while maintaining measurement capability
Solution Approach 2:
The lever member acts as an intermediary that transfers the pivot amount from the pivotal body to the dial gauge. By positioning the lever member radially and having it pivot about a radial axis, it mediates the transmission without requiring axial movement space
2Length of moving object
If the lever member extends in the radial direction to transmit pivot amount, then the axial size is reduced, but the radial size increases
Solution Approach 1:
The lever member is designed to pivot dynamically about a radial axis rather than extending statically in the axial direction. This dynamic pivoting action allows the lever member to transmit the pivot amount with a compact radial footprint, avoiding excessive radial size increase
3Length of moving object
If the pivotal body is held to the leading end side of the holder portion, then the device can be compact, but the pivot amount transmission becomes complex
Solution Approach 1:
The lever member serves multiple functions: it acts as a transmission element for the pivot amount, provides a pivot axis for the pivotal body, and connects the pivotal body to the dial gauge. This multi-functionality simplifies the overall transmission mechanism while maintaining compact dimensions
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
Enables accurate misalignment detection in lathes with limited space between the tool holder mounting portion and the chuck, maintaining compactness in both axial and radial dimensions.
Implementation Method 1
a lever member extending along an intersecting direction intersecting the axial direction at a position which is on the leading end side and which also is on a side closer to the base end side than the pivotal portion is, the lever member being held to the holder portion in such a manner to be pivotable about a pivot axis which is in a direction perpendicular to both the axial direction and the intersecting direction, a pivot amount of the pivotal portion being transmitted to the lever member
Implementation Method 2
a slide member accommodated in the case at a position on more base end side than the lever member and configured to come into contact with the lever member to be movable along the axial direction
Implementation Method 3
a dial gauge fixed to the case with a graduation scale portion thereof being exposed from the case and configured to determine a change amount of a distance

AI summary
Provided is a misalignment determining device having a size thereof in an axial direction being made short. The misalignment determining device includes a case, a dial gauge, a holder portion, a support portion, a pivotal portion, a lever member, and a slide member. The slide member is placed in contact with a stylus of the dial gauge. While the pivotal portion and the lever member are rotated in synchronism with rotation of the holder portion, a pivot amount of the pivotal portion is transmitted to the slide member via the lever member, and based on an amount of movement of the slide member along an axis direction, the dial gauge determines the pivot amount.
