Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a lead screw end polishing machine. Background Technology

[0002] As an indispensable transmission component in the fields of machine tools and precision machinery, ball screws occupy a core position in many industrial applications due to their ability to accurately convert rotary motion into linear motion or efficiently convert torque into axial repetitive force. Their excellent high precision, reversibility and high efficiency make them a key factor in improving the performance of mechanical equipment.

[0003] However, in actual production, the length specifications of ball screws vary and need to be customized according to specific needs. To ensure the stability of the installation, the ends also need to be precision machined. Given that the hardness of ball screw materials generally reaches about HRC60, direct cutting is difficult. Therefore, the cutting area needs to be annealed in advance. However, this step is prone to surface oxidation and discoloration, which affects the surface finish. Therefore, polishing is required to remove the oxide layer and surface defects in order to restore and improve the surface quality.

[0004] In traditional polishing processes, workers hold a ball screw and polish on a high-speed rotating polishing wheel. This method is not only labor-intensive and physically demanding, but also inefficient, leading to a significant increase in overall processing costs. More seriously, this method poses significant safety hazards, as workpieces can easily fly off during polishing, posing a risk of personal injury to operators. Furthermore, the dust pollution generated during polishing is severe; long-term exposure to this environment increases the risk of occupational diseases such as silicosis, posing a long-term threat to workers' health.

[0005] Existing polishing equipment is inconvenient to use and maintain, cannot completely remove rust from the inside of the ball screw tooth grooves, requires a lot of time, has low processing efficiency and cannot guarantee processing quality, greatly increases operating costs, and is neither environmentally friendly nor safe. Currently, there is no equipment on the market specifically for polishing the ends of ball screws.

[0006] To address the above issues, our engineering and technical personnel have developed a specialized, fully automatic ball screw end polishing machine. During polishing, the worker simply places the workpiece on the support rack, adjusts the worktable height and workpiece limiting mechanism according to the ball screw size, closes the door, and the pneumatic equipment completes the workpiece processing in just 3 seconds, significantly improving polishing efficiency. Furthermore, a dust removal mechanism connected to the bottom of the equipment effectively prevents workers from inhaling dust. Utility Model Content
