Gripping Assembly With Integrated Drive for Clamping Device Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping and positioning assemblies for clamping devices in machine tools can only transport the devices between positions but cannot actuate the clamping jaws to open or close, limiting their functionality in handling and processing workpieces.
Innovation Solution
A gripping and positioning assembly with an integrated drive that allows the clamping device to be moved between a clamping and release position, equipped with a motor-driven coupling element and aligning elements for secure connection and positioning, enabling the assembly to actuate the clamping device during transport and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gripping and positioning assembly is designed to transport a clamping device between positions, then transport functionality is achieved, but the ability to actuate the clamping device is lost
Solution Approach 1:
The patent combines the transport function and actuation function into a single integrated gripping and positioning assembly. The assembly includes both gripping elements for holding the clamping device and actuation elements with drives for moving the clamping jaws between open and closed positions, allowing both transport and actuation capabilities in one device.
Solution Approach 2:
The gripping and positioning assembly is designed to perform multiple functions: it can transport the clamping device between different positions and simultaneously actuate the clamping device to open or close the clamping jaws. This multi-functional design eliminates the need for separate transport and actuation systems.
2Adaptability or versatility
If a conventional clamping device is used only for holding workpieces, then simple structure is maintained, but additional functionality for transport and actuation is lost
Solution Approach 1:
The patent merges the clamping device with transport and actuation capabilities by integrating a gripping and positioning assembly that includes both gripping elements for holding the clamping device and actuation elements with drives for moving the clamping jaws, enabling the device to perform multiple operations without requiring separate systems.
3Measurement precision
If aligning elements are added to provide interlocking connection, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent employs asymmetrical aligning elements with specific geometric shapes that provide precise interlocking connections between the gripping and positioning assembly and the clamping device. The aligning elements have complementary shapes that guide and constrain the relative positioning, ensuring accurate alignment while maintaining a relatively simple overall structure.

AI summary
A gripping and positioning assembly for transporting a holding device between different positions includes a coupling arrangement for separably coupling the gripping and positioning assembly to the holding device and holding the holding device securely during transport. The gripping and positioning assembly has an integrated drive for moving the holding device between a hold and a release position to allow the operation of the holding device between a holding and a release position as well as a transporting of the holding device. The coupling arrangement has one or more aligning elements to provide an interlocking connection to the holding device.
