Workbench for supporting and moving articles and machine for machining and cutting articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workbenches for supporting and moving articles during machining processes are fixed and cannot be tilted or inclined, making loading and unloading operations difficult and increasing machining time, and their displacement trajectories are predefined and cannot be adjusted based on machine dimensions or article type.
Innovation Solution
A workbench with a tiltable support surface that can be adjusted through a combination of rotary translation and actuators, allowing variable displacement trajectories controlled by a control unit, enabling flexible positioning and simplifying loading and unloading operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the workbench is fixed and cannot be tilted, then the structure is simple and stable, but the loading and unloading operations become difficult and machining time increases
Solution Approach 1:
The workbench surface is transformed from a fixed static structure to a dynamic tiltable structure. The support surface can be tilted relative to the machine frame through a tilting mechanism, allowing the surface to change its angle during operation. This enables the surface to assume different positions (horizontal for machining, inclined for loading/unloading) thereby improving operational ease without permanently complicating the base structure.
2Ease of operation
If the support surface is made tiltable to simplify loading and unloading, then operational ease improves, but the displacement trajectory becomes predefined and cannot be adjusted for different machine dimensions or article types
Solution Approach 1:
The system incorporates adjustable parameters including tilt angle range and displacement trajectory. The control unit enables programmable adjustment of these parameters to match different machine dimensions and article types. The tilting mechanism can be configured to achieve different angular positions and movement paths, transforming the system from having a fixed predefined trajectory to one with variable adjustable parameters.
3Ease of operation
If a tilting mechanism is added to the workbench, then loading and unloading becomes easier, but the device complexity and potential instability increase
Solution Approach 1:
The control unit receives feedback about the workbench position and tilting state, and automatically adjusts the tilting mechanism to maintain stability during transitions. The system monitors the support surface position and controls the tilting speed and trajectory to prevent oscillations or instability, ensuring the article remains securely positioned throughout the tilting operation.

AI summary
Workbench (1) for supporting and moving articles comprising a frame (22), a support surface (24) able to tilt relative to the frame (22) and pass from an initial horizontal position into a final inclined position, at least one rigid element (30) hinged with the frame (22) at a pivoting point (P) and having an end portion (36) hinged with the surface (24) and at least one first actuator (44) configured to raise and rotate the surface (24) into an intermediate inclined position. The element (30) is shaped as a rocker arm with the pivoting point (P) arranged between a first wing (32) and a second wing (34) and movement means (54) are provided for rotation of the rocker arm (30) about an axis (X2) so as to move the surface (24) from the intermediate position into the final inclined position. The first actuator (44) comprises a first end (46) hinged with the rocker arm (30) and a second end (48) hinged with the support surface (24).
