AI Technical Summary

Technical Problem

The existing CNC machine tool tailstock has a problem of lubricant leakage during use, which leads to lubricant waste and safety hazards in equipment maintenance, and the lubrication is not precise enough.

Method used

An opening and closing assembly was designed, including a ring-shaped opening and closing block that cooperates with the oil supply pipe connection port. Combined with the spring's reset function, it automatically closes the oil supply channel and positions the oil outlet above the rotating shaft of the turntable and tailstock body, thereby achieving precise delivery and channel control of the lubricating fluid.

Benefits of technology

It effectively prevents lubricant leakage, reduces waste, lowers equipment maintenance risks, and improves lubrication efficiency and accuracy.

Abstract

The utility model provides a disc tailstock of a numerical control machine tool, which comprises a tailstock body, the front side of the tailstock body is rotatably matched with a turntable, the bottom of the tailstock body is fixedly provided with a connecting base, the top of the tailstock body is fixedly provided with an oil storage tank, and the front side of the oil storage tank is provided with an oil transportation frame communicated with the oil storage tank. An opening and closing assembly is arranged in the oil conveying frame, a gap is formed between the rotary disc and the tailstock body, and an oil conveying pipe which is communicated with the oil conveying frame and located in the gap is arranged at the bottom of the oil conveying frame. Through the design of the opening and closing assembly, the cooperation of the annular opening and closing block and the oil conveying pipe connecting port and the cooperation of the reset function of the spring, the oil conveying channel can be automatically closed when lubricating liquid is not added, the design that the operation disc is linked with the spiral conveying blade and the annular opening and closing block is adopted, and an operator only needs to simply rotate the operation disc; therefore, lubricating liquid conveying and channel opening and closing control can be synchronously achieved.
