Description

Technical Field

[0001] This utility model relates to the field of press fitting equipment technology, specifically a vortex press fitting equipment. Background Technology

[0002] In today's booming modern manufacturing industry, scroll compressors, as a key piece of highly efficient and energy-saving equipment, are widely used in many fields such as refrigeration, air conditioning, and air compression. In the production process of scroll compressors, the press-fitting of the scroll components is crucial, as its quality directly affects the compressor's performance, reliability, and service life.

[0003] Traditional scroll press-fitting equipment has revealed numerous problems in practical applications. Firstly, its positioning accuracy is insufficient. Early equipment relied primarily on simple mechanical positioning structures when positioning scroll components, making it difficult to accurately align the upper and lower surfaces of the scroll. This resulted in significant concentricity deviations in the pressed-fitted components. Furthermore, previous press-fitting operations relied heavily on manual labor for most steps, requiring frequent human intervention from component placement to process control. This not only led to low production efficiency, failing to meet the demands of large-scale industrial production, but also made it difficult to guarantee the consistency of manual operations. Additionally, it lacked real-time monitoring and feedback mechanisms. Traditional equipment could not accurately monitor key parameters such as pressure and displacement in real time during the press-fitting process, making it difficult to detect abnormalities promptly.
