Compressor Main Frame Guide Structure for One-Step Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for positioning the main frame in compressors require multiple operations and adjustments, leading to low work efficiency and reduced production efficiency due to the need for precise alignment of bolt holes and inner cylindrical holes, which complicates the assembly process.
Innovation Solution
The compressor incorporates a guide structure with a retractable tooling system that uses a guiding cavity and centering cavity to ensure accurate positioning of the main frame within the casing, allowing for one-step alignment and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the existing positioning method using bolt holes and inner cylindrical holes is used, then the main frame can be positioned, but multiple operations and adjustments are required, leading to low work efficiency
Solution Approach 1:
The positioning function is segmented into two distinct structures: the guiding cavity for axial positioning and the centering cavity for radial positioning. This segmentation allows each cavity to be optimized for its specific function, enabling accurate positioning to be achieved through a single operation rather than multiple adjustments.
Solution Approach 2:
The guide structure acts as an intermediary between the main frame and the positioning tooling. The guiding cavity and centering cavity work together as a coordinated system to transfer positioning forces, eliminating the need for workers to perform multiple manual adjustments while maintaining high positioning accuracy.
2Manufacturing precision
If the existing positioning method is used, then positioning can be achieved, but the technical process is complex and affects production efficiency
Solution Approach 1:
The guiding cavity and centering cavity are merged into a single integrated guide structure on the main frame. This combination ensures that axial and radial positioning occur simultaneously through one operation, simplifying the technical process while maintaining high assembly accuracy for the compressor components.
Solution Approach 2:
The guide structure with its dual cavities serves multiple functions: it provides both axial guidance and radial centering, and it works with universal positioning tooling. This multi-functionality eliminates the need for complex, specialized positioning procedures, streamlining the assembly process while ensuring precise component alignment.
3Measurement precision
If the existing positioning method is used, then the main frame can be positioned, but peripheral threads and inner cylindrical holes need to satisfy the tooling, requiring multiple operations
Solution Approach 1:
The guide structure with guiding and centering cavities is pre-configured on the main frame before assembly. This preliminary action ensures that when positioning tooling is applied, both axial and radial positioning occur simultaneously in a single operation, eliminating the need for multiple sequential adjustments and reducing the time required while maintaining high positioning accuracy.
