Rotary Indexing Table Pressure Pin Lock for Tool-Free Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary indexing table assemblies require significant time and additional tools for screw loosening and tightening during setup, leading to increased costs and storage requirements.
Innovation Solution
A rotary indexing table assembly design featuring a pressure pin lock system with a pin assembly that moves along the axis of rotation using a spring system, eliminating the need for screws by transitioning between a set-up and blocking state, allowing for tool-free and rapid assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection arrangement is used to fix the rotary indexing table assembly, then the connection is secure and reliable, but the setup time increases and additional tools are required
Solution Approach 1:
The patent extracts the screw connection arrangement from the system and replaces it with a pressure pin lock mechanism. The pin assembly with movable pin body directly engages with the rotation element, eliminating the need for screws and screwdrivers while maintaining secure connection through spring-loaded engagement forces
Solution Approach 2:
The pin assembly is designed with a spring system that automatically engages and disengages the pin body with the rotation element without requiring external tools. The spring-loaded mechanism provides self-servicing functionality where the connection is made and secured through simple axial movement rather than threaded fastening
2Reliability
If a screw connection arrangement is used to fix the rotary indexing table assembly, then the connection is secure, but the device complexity increases due to additional tools and storage requirements
Solution Approach 1:
The patent removes the screwdriver tool and associated storage requirements from the system. The pressure pin lock mechanism is integrated into the receiving assembly, eliminating the need for separate fastening tools and reducing overall device complexity while maintaining connection reliability
Solution Approach 2:
The pin assembly is merged with the receiving assembly as an integrated unit. The spring system and pin body are combined within the receiving assembly structure, eliminating the need for separate fastening components and tools, thereby simplifying the overall device architecture
3Strength
If screws are used for assembling the rotation element to the receiving assembly, then the connection is fixed securely, but the assembly process requires additional tools and storage space
Solution Approach 1:
The pressure pin lock mechanism enables self-service assembly where the pin body is simply moved axially to engage or disengage from the rotation element. The spring system automatically provides the necessary engagement force, eliminating the need for screwdrivers or other fastening tools while maintaining strong connections
Solution Approach 2:
Instead of using threaded fasteners that require rotational motion and tool intervention, the patent inverts the approach by using a linearly moving pin body that engages through direct axial movement. This reverses the traditional fastening paradigm, making assembly simpler and tool-free while maintaining connection strength

AI summary
A rotary indexing table assembly includes an axis of rotation, a rotation element and a receiving assembly. The rotation element is rotatable about the axis of rotation and has a centering opening coaxial with the axis of rotation. The receiving assembly has a spring system and a pin assembly. The pin assembly has a pin body, movable along the axis of rotation by the spring system and settable in a set-up state or a blocking state. In the set-up state, the rotation element is releasably connected to the receiving assembly, and in the blocking state, the rotation element is fixedly connected to the receiving assembly.
