Lathe Tool Post Layout for Easier Chip Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cut chips from the workpiece accumulate in the large space between the supporting bed and the back tool post in lathes, making it difficult for operators to collect them, especially in obliquely arranged structures.
Innovation Solution
The lathe design positions the second tool post close to the supporting bed, preventing chips from entering the gap between the bed and the tool post, and arranging tools in a way that reduces the machine's size and improves operator access, facilitating chip collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the back tool post is positioned away from the supporting bed to allow tool post movement, then the main tool post can move freely, but chips accumulate in the large space between the bed and tool post making collection difficult
Solution Approach 1:
The patent makes the distance between the back tool post and supporting bed variable rather than fixed. The tool post can be positioned at different distances from the bed depending on the machining requirements, allowing the space to be dynamically adjusted between needing clearance for tool movement and needing minimal space for chip collection
Solution Approach 2:
The patent changes the parameter of tool post positioning distance. By allowing the back tool post to be positioned closer to the supporting bed when chip collection is needed, and farther when tool movement clearance is needed, the system optimizes both requirements through parameter adjustment
2Adaptability or versatility
If the whole structure is obliquely arranged to improve machining capability, then the lathe can perform complex operations, but chips still accumulate in the space between the bed and tool post
Solution Approach 1:
The patent applies local quality by making only the necessary parts of the structure oblique (the machining components) while keeping the supporting bed and chip collection areas horizontal. This allows the lathe to maintain complex machining capability where needed while preventing chip accumulation in the horizontal areas where chips naturally fall and can be easily collected
3Volume of moving object
If the back tool post is positioned closer to the supporting bed to reduce machine size, then the machine becomes more compact, but tool post movement clearance is reduced
Solution Approach 1:
The patent makes the positioning distance between the back tool post and supporting bed dynamically adjustable. The tool post can be positioned closer to reduce machine size when compactness is needed, and moved farther away when tool movement clearance is required, optimizing both requirements through dynamic repositioning

AI summary
Provided is a lathe capable of facilitating the act of collecting chips around the tool post. A lathe 1 comprises a headstock 10, 20, a tool post 40, 50, a supporting bed 30, and a driving unit U2, U3. The first tool post 40 is movably supported on the side 31 of the supporting bed 30. The first tool post driving unit U2 moves the first tool post 40 in a first axis direction (Y1-axis direction) perpendicular to an axis AX1 of a first spindle 11. The second headstock driving unit U3 moves the second headstock 20 in a second axis direction (X2-axis direction) perpendicular to the axis AX1 of the first spindle and oblique to the first axis direction (Y1-axis direction). The second tool post 50 holding the second tool T2 is in a position not overlapping the plurality of first tools T1 in a third axis direction (X1-axis direction) and in a position that the second tool T2 and part of the second tool post 50 on an extension of the second tool T2 (a range R1) overlap the plurality of first tools T1 in the direction of the axis of the first spindle (Z1-axis direction).
