Description

Technical Field

[0001] This utility model relates to the field of bearings, specifically to a spindle inspection air inlet sleeve for bearing production equipment. Background Technology

[0002] As a critical component in mechanical equipment, bearings require extremely high precision and reliability in their manufacturing process. In bearing production equipment, the performance of the spindle directly affects the machining quality of the bearing. Therefore, regular inspection and maintenance of the spindle are necessary. The spindle inspection air inlet sleeve, as an important part of the bearing production equipment, is mainly used to provide clean and stable compressed air to the spindle to meet the functional requirements of pneumatic measurement and air-bearing support during the spindle inspection process.

[0003] Because the spindle dimensions, structures, and testing requirements of different bearing production equipment vary, and traditional air inlet sleeves have fixed specifications and lack compatibility, companies need to purchase multiple compatible air inlet sleeves. This not only increases costs and burdens inventory management, but also reduces equipment efficiency and interrupts the testing process due to frequent replacement of incompatible air inlet sleeves. In addition, during spindle testing and maintenance, air inlet sleeves need to be installed and removed frequently. Traditional air inlet sleeves have complex structures and cumbersome installation and removal processes, which waste a lot of time and manpower. Therefore, we propose an air inlet sleeve for spindle testing of bearing production equipment. Utility Model Content

The filtered gas is transmitted through air intake pipe 1. The bellows 4 at the outlet end of air intake pipe 1 can flexibly change the outlet angle to adapt to the needs of different spindle detection positions. The gas enters the connecting pipe 5 through the bellows 4, and then enters the tee pipe 7 through the sealed assembly structure between the connecting pipe 5 and the tee pipe 7. In the sealed assembly structure, the sleeve 6 connects the connecting pipe 5 and the tee pipe 7 by threads, which not only facilitates disassembly and assembly. The rotating sleeve 6 can also adjust the connection angle. The annular plate 11, sealing tube 10, sealing protrusion 12 and slot 13 cooperate with each other. Through the insertion and sealing structure, the sealing between the connecting tube 5 and the three-way tube 7 is further strengthened to prevent gas leakage. The gas entering the three-way tube 7 is distributed to two functional ends. The pneumatic detection connection structure at one end adapts to spindles of different diameters through different hole diameters on the stepped hole protrusion 14. The sealing strip 16 and the rubber sheet 8 work together to ensure the sealing of the connection with the spindle, so that the gas can stably participate in the spindle performance detection. The nozzle 9 at the other end sprays out the gas to achieve the function of cleaning or cooling the spindle during the spindle detection process.
