Pump Cylinder Centering via Positioning Detection Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor assembly technologies are inefficient and labor-intensive due to the manual adjustment of clearance between the middle cylinder and the rolling rotor, which hinders automatic assembly and affects production efficiency.
Innovation Solution
A pump body assembly with positioning detection portions on multiple cylinder assemblies, forming preset included angles to facilitate automatic alignment and centering, allowing for precise positioning and assembly of the first, second, and third cylinder assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment is used for centering the middle cylinder, then positioning precision can be achieved, but assembly time and labor consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-setting the geometric center line of the positioning detection portion at a specific preset included angle with the sliding-vane groove extension line. This pre-established geometric relationship enables automatic centering during assembly without requiring manual adjustment, thus achieving both high precision and reduced assembly time.
Solution Approach 2:
The patent introduces a positioning detection portion as an intermediary element that facilitates automatic centering. This detection portion, with its specifically oriented geometric center line, acts as a mediator between the cylinder and the rotor, enabling precise alignment through automatic detection and positioning rather than manual intervention.
2Productivity
If automatic assembly technology is applied to multi-cylinder compressors, then assembly efficiency improves, but the middle cylinder cannot be automatically centered
Solution Approach 1:
The patent applies segmentation by dividing the centering function into distinct components: the positioning detection portion with its specifically oriented geometric center line. This segmentation allows the middle cylinder to be automatically centered through the detection portion's geometric relationship, completing the automation process for all three cylinders including the previously problematic middle cylinder.
Solution Approach 2:
The patent utilizes parameter changes by establishing a specific preset included angle between the geometric center line of the positioning detection portion and the extension line of the sliding-vane groove. This angular parameter enables the automatic centering mechanism to function correctly, allowing the middle cylinder to be automatically positioned with the same efficiency as the upper and lower cylinders.
3Manufacturing precision
If manual centering adjustment is performed for the middle cylinder, then positioning accuracy is maintained, but production efficiency deteriorates
Solution Approach 1:
The patent applies self-service by designing the positioning detection portion with its geometric center line inherently oriented at the preset included angle. This self-configuring geometric relationship allows the system to automatically achieve accurate clearance fit for the middle cylinder without external manual intervention, thereby maintaining precision while dramatically improving production efficiency.
