Sliding Cutting Machine Layout for Visibility and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding cutting machines face challenges in maintaining high machine rigidity and cutting accuracy due to the obstruction of visibility by motor housings and slide bars, which affects the user's ability to confirm the cutting location and increases the distance between the cutting tool and slide bars, leading to reduced precision.
Innovation Solution
The sliding cutting machine design positions the electric motor and motive-power transmitting part between the cutting tool and slide bars, allowing the cutting tool to be closer to the slide bars, improving visibility and maintaining high machine rigidity by reducing the distance between the cutting tool and slide bars, and using a compact motor shaft orientation to minimize protrusion and enhance support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electric motor is disposed proximate to the cutting tool, then the machine structure is compact, but the spacing between the cutting tool and slide bar increases, reducing machine rigidity and cutting accuracy
Solution Approach 1:
The patent repositions the electric motor from a horizontal arrangement (beside the cutting tool) to a vertical arrangement (above the cutting tool). This dimensional change allows the motor to be compactly integrated while maintaining minimal spacing between the cutting tool and slide bar, thus preserving cutting accuracy while achieving structural compactness.
2Ease of operation
If the motor housing protrudes leftward of the cutting tool, then the electric motor can be positioned to drive the cutting tool, but it obstructs the user's visibility of the cutting location
Solution Approach 1:
Instead of having the motor housing protrude leftward (toward the user), the patent inverts the arrangement by positioning the motor above the cutting tool with the housing extending rightward (away from the user). This inversion eliminates the visibility obstruction while maintaining the motor's driving function.
3Adaptability or versatility
If the slide bars extend beside the cutting tool, then the cutting machine can slide along the extension direction, but the slide bars obstruct the user's visibility of the cutting location
Solution Approach 1:
The patent repositions the slide bars from a position beside the cutting tool (horizontal arrangement) to a position above the cutting tool (vertical arrangement). This dimensional change allows the sliding mechanism to function while clearing the user's line of sight to the cutting location.

AI summary
A sliding cutting machine (1) includes: slide bars (51); a slide base (52), which slides along the slide bars; and a cutting-machine main body (10), which is swingable in an up-down direction about an up-down swing (pivot) shaft (10a) provided on the slide base. The cutting-machine main body includes: an output shaft (37) extending in an axial direction orthogonal to the slide bars and mounting a cutting tool (11); an electric motor (23) between the cutting tool and the slide bars when the cutting tool is vertical, and located more upward than the slide bars; and a motive-power transmitting part (30) transmitting the driving force of the electric motor to the output shaft. The motive-power transmitting part is between the cutting tool and the slide bars and upward of the slide bars when the cutting-machine main body is at a top dead center.
