Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool rests for machine tools face difficulties in achieving simultaneous engagement of engaging portions with engaged portions due to complex power transmission mechanisms.
Innovation Solution
A tool rest design with adjustable engaging portions and fixing means, allowing for precise phase alignment of engaging and engaged portions via a gear wheel mechanism, ensuring simultaneous engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a power transmission mechanism with a clutch mechanism is used to transmit driving power to each rotary tool, then the rotary tools can be driven in rotation, but simultaneous engagement of engaging portions with engaged portions becomes difficult to achieve
Solution Approach 1:
The input portions are made adjustable in their angular positions relative to the tool-rotating drive shaft, allowing dynamic repositioning to achieve simultaneous engagement. Each input portion can be independently positioned and fixed at different phases, transforming a static fixed-position mechanism into a dynamically adjustable one that facilitates easy simultaneous engagement while maintaining operational functionality.
2Manufacturing precision
If the phase of engaging portions is not adjustable, then the structure remains simple, but simultaneous engagement with engaged portions cannot be easily achieved
Solution Approach 1:
The power transmission mechanism is segmented into multiple independent input portions, each with its own adjustable phase position. This segmentation allows each input portion to be independently adjusted and fixed at precise angular positions, enabling accurate phase alignment for simultaneous engagement without requiring complex centralized adjustment mechanisms.
Solution Approach 2:
The input portions are pre-adjusted to specific angular positions during assembly or setup, and then fixed in place using fixing means. This preliminary adjustment and fixation approach ensures precise phase alignment is achieved before operation, eliminating the need for complex real-time adjustment mechanisms during machine operation.

AI summary
A tool rest (1) for a machine tool, with a plurality of rotary tools (8) and a tool-rotating drive shaft (10) supported rotatably so that its rotation is transmitted to each rotary tool (8). The tool rest includes: a plurality of input portions (21, 31) fixed to the tool-rotating drive shaft (10); and engaging portions (23a, 33a) corresponding to the respective input portions (21, 31), rotatably supported and adopted to be driven in rotation by the input portions (21, 31) for engaging with engaged portions (8c) of each rotary tool (8) to transmit power when a prescribed rotational phase is reached. Adjusting means (40) is provided between a prescribed input portion (21) and the engaging portion (23a), for adjusting the phase of the engaging portion (23a) relative to the tool-rotating drive shaft (10) such that the engaging portions (23a, 33a) and the corresponding engaged portions (8c) are engaged simultaneously.
