Supplementary Workpiece Support With Pivoting Stop for Profile Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for workpieces in machine tools, such as sawing machines, lack flexibility and are not adequately suited for processing profile parts that require additional support, particularly in applications involving ceiling strips and other elongated materials.
Innovation Solution
An additional support device with an adjustable transverse stop body and a carrier body that can pivot and slide, allowing for optimal positioning of the workpiece support surface relative to the base support surface, enabling the support of plate-like and strip-like workpieces without the need for a transverse stop surface, and allowing for easy processing of ceiling strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support device is used, then the structure is simple, but the flexibility for different workpiece shapes is insufficient
Solution Approach 1:
The support body is designed to be pivotable and slidable relative to the carrier body, allowing dynamic adjustment of the additional support surface position and angle. This enables the device to adapt to different workpiece shapes and sizes while maintaining a relatively simple overall structure that can be adjusted rather than requiring multiple fixed configurations
Solution Approach 2:
The adjustable support body serves multiple functions: it can be positioned at different locations, angled at different orientations, and configured to support various workpiece types including plate-like and strip-like workpieces. This multi-functionality replaces what would otherwise require multiple separate support devices
2Adaptability or versatility
If the additional support surface is positioned close to the base support surface, then the support is stable, but the workpiece cannot bridge gaps effectively
Solution Approach 1:
The pivotable and slidable support body allows the additional support surface to be dynamically positioned at optimal distances from the base support surface. This enables the support system to accommodate workpieces that need to bridge gaps while maintaining stability through adjustable positioning rather than fixed close proximity
3Ease of operation
If the support body is fixed in position, then the device is simple to manufacture, but the support body cannot be brought into optimal position
Solution Approach 1:
The support body incorporates pivotable and slidable mechanisms that allow it to be easily adjusted to optimal positions during operation. These adjustment mechanisms are designed to be simple enough to maintain reasonable manufacturing ease while providing the necessary positioning flexibility for different workpiece requirements

AI summary
The invention relates to a supplementary support assembly (60) for a workpiece support assembly (50) of a semi-stationary machine tool (20), particularly a machine saw, wherein a workpiece support body (51) of the workpiece support assembly (50) has a base supporting surface (53), which is substantially horizontal in use, for supporting a workpiece (W1,W2) for processing, particularly for sawing (SX) by a tool (24) of the machine tool (20), wherein the supplementary support assembly has a supplementary supporting surface (81) and a support body (70) with support body mounting means (61) for detachably mounting on the workpiece support assembly (50), wherein when the supplementary support assembly is mounted on the workpiece support assembly (50) the supplementary supporting surface (81) is at least substantially aligned with the base supporting surface (53). The supplementary support assembly comprises a support body (80) which is mounted by means of a support body bearing (85) comprising a sliding bearing (85A) and/or a pivoting bearing (85B) on the support body (70) to be movable between at least two different positions relative to the base supporting surface (53) and can be detachably fixed on the support body (70) in the relative positions by means of supporting body fixing means (66), wherein the supporting body (80) comprises the supplementary supporting surface (81) and/or forms a mounting base for a transverse stop body (90) which may be detachably mounted on the supporting body (80) by means of stop body fixing means (99) and has at least one transverse stop face (93, 94) which is at an angle to the supplementary supporting surface (81), particularly at a right-angle thereto.
