The installation and maintenance of steel linear rails are important links to ensure their normal operation and extend their service life.
1. Installation Steps
1.1 Place the Steel Linear Rails
Gently place the linear guide on the installation surface and ensure that the guide is parallel to the installation surface. Use a caliper or ruler to check the parallelism between the guide and the installation surface to ensure installation accuracy.
1.2 Preliminary Fixation of the Steel Linear Rail
Use screws to initially fix the linear guide on the installation surface, but do not tighten it completely. At this time, ensure that the guide is lightly against the installation surface to avoid deformation of the guide due to overtightening.
1.3 Assemble the Side Pressure Plate
If the design requires, install the side pressure plate, and do not tighten it completely. The side pressure plate helps to increase the stability of the guide.
1.4 Tighten the Screws in Sequence
Adjust the torque value of the torque wrench as required, and tighten the screws in sequence. Usually, start from the center and then gradually tighten to both ends to ensure that the guide is evenly stressed. First tighten the screws of the side pressure plate to ensure that they are tightened.
1.5 Install Other Linear Guides
If the equipment requires multiple steel linear rails, install the other guides in the same way to ensure the installation accuracy and stability of each guide.
1.6 Adjust the Parallelism and Straightness of the Guide Rail
Use a marble ruler or other measuring tools to check the parallelism and straightness of the guide rail. Adjust the height and position of the guide rail by adjusting the tightness of the screws to meet the design requirements.
1.7 Install the Slider
Install the slider on the steel linear rail to ensure that the slider can slide smoothly. Pay attention to the direction of the slider to ensure that it is consistent with the direction of movement of the guide rail.
1.8 Install the Hole Cover
Punch the hole cover into the assembly bolt hole until it is on the same plane as the top surface of the linear guide rail. The hole cover helps prevent dust and debris from entering the interior of the guide rail.
2. Correction and Adjustment
After the installation is completed, it is necessary to perform corrections and adjustments.
2.1 Verticality
It is necessary to check the flatness of the steel linear rail, that is, the verticality between the plane where the guide rail is located and the installation reference plane. You can use precision instruments to measure, and then adjust the installation position of the guide rail according to the measurement results to achieve the required verticality.
2.2 Parallelism
It is necessary to check the parallelism of the guide rail, that is, the degree of parallelism between multiple guide rails. By measuring and adjusting the spacing between the guide rails, ensure that the guide rails are parallel and evenly spaced.
2.3 Other Parameters
It is also necessary to check the straightness and coaxiality of the guide rail and other parameters to ensure the movement accuracy of the guide rail in all directions.
3. Maintenance of Steel Linear Rails
3.1 Regular Cleaning
Since the linear guide rail is always in working condition, it is easy to be attached to oil and dust around it. At the same time, when the iron filings generated by the workpiece fall from the bead groove, the steel surface is fatigued and overloaded, the steel beads will fall off. If they are not cleaned in time, it will affect the service life of the guide rail.
Therefore, we should clean the linear guide rail every once in a while.
Operation Steps
First, use special tools to remove the dust on the steel linear rail, then wipe the surface of the guide rail with detergent, and finally wipe it with a clean soft cloth. This ensures that the surface of the guide rail remains clean and will not affect the work.
3.2 Regular Lubrication
The linear guide rail moves on the guide rail by the slider. In order to reduce the friction between the slider and the guide rail and ensure its smooth movement, we need to lubricate the linear guide rail regularly. The lubrication of the linear guide rail has an important influence on the operating status and life of the machine tool. The lubrication should be determined according to the different use environments.
Operation Steps
Before lubrication, the surface of the guide rail needs to be cleaned and then coated with special lubricating oil or grease. Lubricating oil or grease should be of appropriate brand and model to ensure its lubrication effect. The frequency of lubrication should be determined according to the usage. Generally speaking, if it is used frequently, it needs to be lubricated more frequently.
3.3 Regular Inspection and Maintenance
Regularly check the wear and deformation of the steel linear rail. If there is damage, replace the bad linear guide rail in time to avoid production damage caused by the damage of the linear guide rail, which causes the machine tool processing accuracy and rigidity to be reduced.
Precautions
For regular maintenance intervals, it is generally once every 3 months according to the equipment's own status and surrounding environmental conditions, and the interval time can also be slightly extended according to actual conditions.
Summary
Through the above installation and maintenance steps, the normal operation of the steel linear rails can be effectively ensured, its service life can be extended, and the overall performance of the equipment can be improved.
