Specific solutions for excessive parallelism in the installation of Hanyi ball spline

1. Solution to installation foundation issues
Foundation flatness repair: - If the poor flatness of the installation base causes the parallelism of the ball spline to exceed the standard, the first step is to repair the base plane. For situations where the flatness deviation is small (such as within 0.1mm), grinding can be used. Using a grinding plate and grinding paste, grind the base plane relative to the grinding plate, and continuously check the flatness (such as using a level or optical flat crystal) until the flatness meets the requirements. Generally, the flatness error should be controlled within 0.02mm. -For situations with significant flatness deviation, mechanical processing methods can be used. For example, when using a milling machine to mill the base plane, the flatness after reprocessing should meet the accuracy requirements for equipment installation. At the same time, attention should be paid to the surface roughness after machining, and the surface roughness Ra value should be controlled between 1.6 μ m and 3.2 μ m to ensure good contact performance.
Base reinforcement and anti loosening: - When the base installation is unstable, it is necessary to reinforce the base. Check the support structure of the base. For areas with insufficient strength, reinforcement bars can be added or thicker support plates can be replaced. For example, in some large equipment, if the base is a welded steel plate structure, angle steel can be welded at key locations as reinforcement bars to improve the overall rigidity of the base. -To prevent the base from loosening during operation, appropriate fastening methods should be used. For screw connected bases, anti loosening nuts or spring washers can be used. At the same time, screws should be tightened according to the prescribed torque, usually using a torque wrench. According to the specifications and equipment requirements of the screws, the torque should be controlled within a reasonable range. For example, for M10 screws, the torque can be controlled between 40-60N · m.
