Technical Field

[0001] The invention relates to the technical field of machine tool accessories, in particular to a screw rod adjusting mechanism of a metal chip cutting machine tool. Background Art

[0002] Ball screw is the most commonly used transmission element in metal chip cutting machine tools. Its main function is to convert rotational motion into linear motion, or to convert torque into axial repetitive force. It also has the characteristics of high precision, reversibility and high efficiency.

[0003] After searching, the Chinese patent publication number CN110625430A discloses a dust removal and temperature adjustment device for a CNC lathe screw, including a screw, a lathe is arranged on one side of the screw, a wire ring is arranged around the center of the screw, a connecting plate is arranged on the side of the wire ring away from the lathe, a rotating ring is arranged at one end of the screw, a power output shaft is arranged at the end of the screw away from the rotating ring, and a sliding rod is arranged horizontally at the bottom of the screw. Although this technical solution can absorb the heat of the steel ball and remove impurities inside the groove of the wire ring, when in use, the surface of the screw is often coated with lubricating oil, and the cleaning effect of impurities in the lubricating oil by brushing is limited, and the cooling water can only dissipate heat to the steel ball, while the heat inside the screw cannot be quickly dissipated, thereby reducing the heat dissipation and cleaning effect, and after long-term use, the lubricating oil and impurities will adhere to the brush, which is inconvenient to clean and recycle, thereby affecting the later maintenance.

[0004] The Chinese patent publication number CN221347769U discloses a screw adjustment device for a machine tool, comprising two symmetrically arranged vertical plates, a horizontal plate fixed at the lower end of the two vertical plates, a screw body rotatably connected between the two vertical plates, and a fixed plate fixed on the side of the vertical plates. Although the heat-conducting copper tube of this technical solution can absorb the heat generated by the screw body, the water in the tube needs to be replaced after each processing, which is cumbersome to operate, and the screw is exposed to the outside, and debris and dust are easy to fall on it, thereby affecting its normal operation.
