Dual-Stage Slide Mechanism for Table Cutting Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing table cutting machines, particularly those with a single slide mechanism for long slide distances, suffer from operational inefficiencies due to the obstruction caused by the slide bar, which hinders visual observation of the blade edge during cutting operations, leading to uncomfortable postures and reduced performance.
Innovation Solution
The implementation of a table cutting machine with a dual-stage slide mechanism where the slide guiding member is fixed to prevent rearward projection, allowing for a long slide distance without obstructing the cutting operation and improving visibility by shortening the slide guiding member's length, and arranging the slide mechanisms to avoid projecting towards the user's side, enabling better access to the blade edge.

Engineering Contradiction Analysis
1Length of moving object
If a single slide mechanism is used to obtain a long slide distance for cutting large size material, then the slide distance is increased, but the slide bar becomes longer and obstructs the visual observation of the blade edge
Solution Approach 1:
The slide mechanism is divided into two independent stages: a lower stage slide mechanism (20) and an upper stage slide mechanism (40). Each stage has its own slide bars (22, 42) that can move independently. This segmentation allows the main body to achieve a long total slide distance while each individual slide bar remains relatively short and does not obstruct the operator's view of the blade edge.
2Area of stationary object
If the slide bar is fixed to project forward from the supporting arm, then no rearward space is required and the machine can be placed closely to a wall, but the slide bar always extends over the material and hinders visual observation
Solution Approach 1:
The slide mechanisms are arranged in two different vertical dimensions (levels). The lower stage slide mechanism is positioned at a lower vertical level while the upper stage slide mechanism is positioned at a higher vertical level. This dimensional arrangement allows both slide bars to coexist without overlapping in the horizontal plane where the cutting operation occurs, eliminating the obstruction problem while maintaining compact rearward space.
3Ease of operation
If the upper stage slide mechanism is positioned to not project forward from the rotational center, then the slide bar does not obstruct the cutting operation, but the mechanism becomes more complex
Solution Approach 1:
The cutting machine is divided into functionally independent slide stages. The upper stage slide mechanism handles fine positioning and adjustment functions, while the lower stage slide mechanism handles coarse positioning. This functional segmentation allows each mechanism to be optimized for its specific purpose without requiring complex interactions between them, making the overall system manageable despite having multiple stages.

AI summary
In a table cutting machine capable of sliding a main body of the cutting machine in the backward and forward direction for the purpose of processing a large size material to be cut, a rearward installation space can be reduced by configuring the cutting machine in such a way that a slide bar of a slide mechanism for slidably supporting the main body of the cutting machine is fixed while a bearing side is adapted to be movable. However, this has caused a problem that the fixed slide bar obstructs an operation. In accordance with the present invention, the rearward installation space can be reduced and good visibility of the edge of a blade can be obtained, and thus an operational performance is improved. Slide mechanisms (20 and 40) arranged in two stages in the vertical direction are used for obtaining a long slide distance for a main body of a cutting machine (10). For the upper stage slide mechanism, there is adopted the slide mechanism (40) of a pattern 2 in which a slide bar (42) is fixed. This allows the rearward installation space of the slide mechanism (40) to be reduced, and ensures good visibility of the edge of a blade.
