Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a ball screw structure for mechanical processing. Background Art

[0002] A ball screw is a device used for linear motion transmission. It is often used in industrial machinery and equipment to convert rotary motion into linear motion or linear motion into rotary motion. Compared with ordinary threaded screw transmission, ball screws have higher transmission efficiency, smaller friction resistance and higher precision. This makes ball screws widely used in the field of linear motion transmission that requires high speed, high precision and high load, such as CNC machine tools, automated production equipment, injection molding machinery and other fields. Ball screws are widely used in mechanical processing. Ball screws are often used in the feed system and transmission system of CNC machine tools. They can achieve precise linear motion control and improve processing accuracy and efficiency. On lathes, ball screws are used to move the spindle and beam, control the feed and cutting speed of the workpiece, and improve the accuracy and efficiency of turning.

[0003] In the process of grinding or cutting parts of ball screws in mechanical processing applications, metal debris is easy to fly everywhere. The surface of the ball screw that is exposed for a long time will inevitably stick to some debris. If it is not cleaned in time, it will easily cause additional wear during the sliding process. Most of the existing technologies are to connect a bellows on the surface of the screw to achieve the effect of blocking debris. However, the balls inside the ball screw will also drop debris due to long-term operation during the movement, and the use of bellows will easily make it impossible to discharge the debris generated inside, which will easily cause the screw to get stuck after long-term use.

[0004] In view of this, we propose a ball screw structure for machining. Utility Model Content
