Several methods to install linear guides
With the widespread use of high-precision linear guides in industrial automation, it is necessary to master certain installation skills, master the correct method of installing linear guides, and improve the service life and accuracy of the guides.
In the installation without lateral positioning assembly surface, to ensure the parallelism between the driven side slide rail and the reference side slide rail.
1. Use the installation datum surface installation method
First use the assembly screws to fix the bottom reference surface of the linear guide to the bottom assembly surface of the bed, then use a vise to press the side reference surface of the slide rail against the side assembly surface of the bed to determine the position of the slide rail, then use a torque wrench, Tighten the fixing screws in sequence with a certain torque, and press the bottom reference surface of the slide rail against the assembly surface of the bottom of the bed.
2. Installation of the linear guide on the driven side
1. Straight-line block gauge method
Place the linear block gauge between the two linear guide rails, use a micrometer to calibrate the linear block gauge so that it is parallel to the side reference surface of the reference side slide rail, and then calibrate the driven side slide rail and driven rail according to the linear block gauge Start calibration and tighten the assembly screws with specific torque in sequence.
2. Mobile platform law
Fix the two sliders on the reference side on a measuring platform, while only one slider is installed on the driven side. Neither the slide rail nor the slider is fixed to the bed and platform. Use the top surface of the slider attached to the driven side. The submeter measures the side reference surface of the driven side slider, and the one end of the driven linear guide is calibrated and the assembly screws are tightened with a specific torque in sequence.
3. Follow the standard side slide method
Fix one of the two slide blocks of the reference side linear guide rail and the driven side guide rail to the platform, and then fix the driven side slide rail and the other slide rail to the bed and platform approximately respectively to slide on the reference side The rail is the mobile platform. Starting from one end of the slide rail, while confirming the rolling resistance of the linear guide on the driven side, tighten the assembly screws with a specific torque in sequence.
4. Special tool method
Use professional tools to determine the position of the driven side slide rail, and tighten the assembly screws with a specific torque in sequence.
