Problems solved by technology

However, in the process of injecting liquid into the liquid-jet type online dynamic balance terminal device, since there is no closed channel, the liquid is easy to splash, so that less liquid flows into the cavity of the terminal device, which will not only cause pollution, but also seriously affect the online dynamic balance. The effect of balance, affecting the quality of the processed workpiece

Abstract

A liquid injection type online dynamic balance terminal suitable for a large-external-diameter external thread grinder spindle comprises a grinding wheel base plate connected with the spindle. The grinding wheel base plate and a grinding wheel end cover are connected with a tightening grinding wheel. The grinding wheel base plate is connected with a rotary connector rotor. The rotary connector rotor is in clearance fit with a rotary connector stator. The rotary connector stator is fixed to a case. Second liquid guide holes are formed in the rotary connector stator. Annular liquid guide grooves are formed in the external diameter of the rotary connector rotor. First liquid guide holes are evenly distributed in the rotary connector rotor in the circumferential direction. The two ends of the first liquid guide holes communicate with the annular liquid guide grooves and liquid containing cavities which are evenly distributed in the grinding wheel base plate in the circumferential direction correspondingly. A sealed liquid channel is formed from a hydraulic system to the liquid containing cavities through PVC pipes, quick couplings, the second liquid guide holes, the annular liquid guide grooves and the first liquid guide holes. According to the liquid injection type online dynamic balance terminal, automatic online dynamic balance compensation of the large-external-diameter external thread grinder spindle in the grinding machining process is achieved, the sealed runner is formed, liquid splash is avoided, and the quality and efficiency of grinding machining are effectively improved.

Description

technical field [0001] The invention relates to the technical field of an online dynamic balance terminal for a grinding machine spindle, in particular to a liquid-spraying online dynamic balance terminal suitable for a large-diameter external thread grinder spindle. Background technique [0002] As the main working part of the grinding machine, the spindle of the grinding machine is in good or bad state during the grinding process, which will directly affect the quality of the processed parts. The unbalanced amount will cause a large vibration of the spindle, which will further affect the quality of the processed parts. quality. At the processing site, some large workpieces need to be ground and finished, such as the raceway of the screw, and an external thread grinder with a large outer diameter is required. The spindle speed of the external thread grinder with large outer diameter is relatively low, but due to the relatively large radius of the grinding wheel installed o...
