With the development of industrial automation, high-precision linear guides are increasingly widely used. It is crucial to master the correct installation techniques in order to fully utilize its performance. During the installation process, it is necessary to ensure that the driven side slide rail is highly parallel to the reference side slide rail, which not only extends the service life of the guide rail but also improves its accuracy of use.
1.Adopting the benchmark installation method
When installing high-precision linear guides, it is recommended to use the reference surface installation method. The key to this method is to ensure the high parallelism between the driven side slide rail and the reference side slide rail. By using appropriate installation techniques, not only can the service life of the guide rail be extended, but its accuracy can also be significantly improved, thus fully leveraging the performance advantages of high-precision linear guides.
Firstly, with the help of assembly screws, preliminarily fix the reference surface at the bottom of the linear guide rail onto the assembly surface at the bottom of the bed. Subsequently, use a vise to tightly fit the reference surface on the side of the slide rail to the assembly surface on the side of the bed, thereby accurately determining the position of the slide rail. Finally, use a torque wrench to tighten the fixing screws in a certain order of torque, ensuring that the reference surface at the bottom of the slide rail is tightly pressed against the assembly surface at the bottom of the bed.
2.Installation of the driven side of the linear guide rail
When installing the driven side of a linear guide, certain steps and precautions need to be followed to ensure the accuracy and stability of the installation. Firstly, it is necessary to ensure the cleanliness and smoothness of the workbench in order to provide a good foundation for the installation of the guide rail. Secondly, select appropriate installation tools and materials based on the specific model and specifications of the guide rail. During the installation process, the position and angle of the guide rail should be carefully adjusted to ensure a tight fit with the workbench. Finally, use appropriate fasteners to firmly secure the guide rail to the workbench to ensure its stability and durability during use. By following these steps, the installation of the driven side of the linear guide can be effectively completed.
(1) Straight-line block gauge method
When installing the driven side of the linear guide rail, the linear block gauge method can be used for precise adjustment. By using a linear block gauge, it is easy to measure and adjust the position and angle of the guide rail, ensuring a perfect fit with the workbench. This method is simple and effective, and can significantly improve the accuracy and efficiency of installation.
Accurately place the linear block gauge between two linear guides, calibrate the linear block gauge using a micrometer, and ensure that it remains parallel to the side reference surface of the reference side slide rail. Next, according to the instructions of the linear block gauge, calibrate the driven side slide rail, starting from one end and sequentially locking the assembly screws with a specific torque to complete precise adjustment
(2)Using a mobile platform for calibration
After placing the linear block gauge between two linear guides, fine tune the linear block gauge by moving the platform to ensure that it remains highly parallel to the side reference surface of the reference side slide rail. Subsequently, following the guidance of the linear block gauge, fine calibration was carried out on the driven side slide rail, and the assembly screws were sequentially tightened with appropriate torque to achieve a more precise adjustment effect.
Place the two sliders on the reference side firmly on the measuring platform, while only one slider is assembled on the driven side. At this point, the slide rail and slider have not been fully secured to the bed and platform. Next, using the micrometer attached to the top surface of the driven side slider, we measure the side reference plane of the driven side slider and calibrate it starting from one end of the linear guide. During the calibration process, we need to tighten the assembly screws one by one with a specific torque to ensure precise adjustment results.
(3)Follow the calibration method of the reference side slide rail
After completing the measurement and calibration of the side reference surface of the driven side slider, we need to follow the calibration method of the reference side slider and perform similar calibration work on the driven side slider. The purpose of doing this is to ensure that the calibration results of the sliding rails on both sides are consistent, thereby providing a stable reference for subsequent mechanical processing.
Place the two sliders of the reference side linear guide rail and one slider of the driven side guide rail firmly on the platform, and then roughly fix the driven side guide rail and its other slider on the bed and platform. On the premise of keeping the reference side sliding rail stationary, move the platform and start from one end of the sliding rail, checking the rolling resistance of the driven side linear guide rail while tightening the assembly screws with a specific torque in sequence.
(4)Application of specialized tools
During the assembly process, we can use specialized tools to ensure precise and efficient assembly. These tools have been carefully designed to effectively reduce operational difficulty and improve assembly quality. By using specialized tools, we can more easily complete the rolling resistance inspection and screw tightening work of the driven side linear guide.
During the assembly process, we use professional tools to accurately position the driven side slide rail and tighten the assembly screws one by one according to the specified torque sequence to ensure the accuracy and stability of the assembly.
