Rotary Worktable Drive Layout for Continuous Machining Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work processing apparatuses for thermal spray or clad processing are limited in the range of processing contents and types of work pieces due to restrictions in rotation and wiring entanglement of motor systems.
Innovation Solution
A work processing apparatus with a rotatable work table, a table displacement mechanism, and a control system that allows for independent drive source connection and disconnection, enabling continuous rotation and high-speed operation without considering motor wiring, along with a weight holding tool for balance and adjustable centrifugal force, and input/output mechanisms for hydraulic, pneumatic, or electrical signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the work table is rotatably driven with motors mounted on it, then the work table can be rotated for processing, but the wiring of the motors becomes entangled and limits continuous rotation
Solution Approach 1:
The patent extracts the motors from the rotating work table and places them on the stationary table rotary drive apparatus. This separation allows the work table to rotate freely without motor wiring entanglement, while the motors remain stationary and can be continuously operated. The drive force is transmitted through the table rotary drive apparatus which rotates with the work table.
Solution Approach 2:
The table rotary drive apparatus serves as an intermediary between the stationary motors and the rotating work table. It receives drive force from the stationary motors and transmits it to the work table, enabling rotation without direct motor mounting on the rotating table. This mediator resolves the conflict between needing rotation and avoiding wiring entanglement.
2Speed
If the table displacement mechanism drive apparatus is fixedly connected to the table displacement mechanism, then drive force can be continuously transmitted, but the work table cannot be rotated due to wiring constraints
Solution Approach 1:
The patent makes the connection between the table displacement mechanism drive apparatus and the table displacement mechanism dynamic rather than fixed. The drive source displacement apparatus enables the drive apparatus to approach and connect to the displacement mechanism only when needed, and separate when rotation is required. This dynamic connection allows both high-speed rotation and reliable drive force transmission at appropriate times.
Solution Approach 2:
The system operates in periodic cycles: the drive source displacement apparatus connects the table displacement mechanism drive apparatus to the displacement mechanism for driving operations, then separates to allow rotation. This periodic connection and separation enables the work table to perform both displacement and rotation functions effectively.
3Adaptability or versatility
If the work table rotates forward and reverse multiple times, then processing versatility increases, but wiring entanglement prevents continuous rotation in one direction
Solution Approach 1:
By extracting the motors from the rotating work table and placing them on the stationary table rotary drive apparatus, the patent eliminates the wiring entanglement problem that previously limited rotation flexibility. The work table can now rotate forward and reverse multiple times without wiring constraints, while the stationary motors continue to provide drive force through the table rotary drive apparatus.

AI summary
Provided is a work processing apparatus configured so that limitations on the contents of processing for a work piece or the type of work piece can be reduced and processing for a wider range of processing contents and work piece can be performed. In a work processing apparatus 100, a work table 101 is, through a table displacement mechanism 103, supported on a rotation base 120 to be rotatably driven by a table rotary drive motor 125, and a weight holding tool 110 is supported on the rotation base 120 through a weight displacement mechanism 114. The table displacement mechanism 114 includes a rack-and-pinion mechanism configured to displace the work table 101 in an X-axis direction as viewed in the figure. At the table displacement mechanism 114, a power inputter 108 configured to input drive force from a table displacement mechanism drive apparatus 130 is provided. The table displacement mechanism drive apparatus 130 is, by a drive source displacement apparatus 132, connected to or disconnected from the table displacement mechanism drive apparatus 130.
