Principle of horizontal adjustment of guide rail.
The horizontal state of guide rail has an important influence on the accuracy and stability of mechanical equipment. Adjusting the level of the guide rail can be achieved by adjusting the shim between the guide rail shim and the foundation shim. This is because the different thickness of the shim will form different support heights for the guide rail, thus adjusting the horizontal state of the guide rail.
Steps for horizontal adjustment of guide rail.
1. Determine the horizontal state of the guide rail.
First, you need to determine whether the guide rail is horizontal. This can be determined by measuring the heights of several points on the guide rail. If the height difference is not greater than the specified standard, it is a horizontal state.
2. Remove the shim
Remove the foundation pad under the guide rail and the guide rail pad separately, and clean the pad surfaces of the guide rail and the foundation pad.
Step 3 add shim
According to the height difference just determined, select the shim with appropriate thickness, and add the shim between the guide rail shim and the foundation shim to make the guide rail level.
4. Lock the shim
Reinforce the pad iron between the guide rail and the foundation pad iron, and measure whether the guide rail reaches the horizontal state again.
5. Determine the adjusted horizontal state.
The operation process may affect other parts, so it is necessary to confirm the horizontal state of the guide rail again.
Matters needing attention in adjusting the level of guide rail.
1. Adjust the guide rail level carefully and operate carefully to avoid damaging the guide rail.
2. Before adjustment, it is necessary to check whether the machine tool foundation of the guide rail meets the standard, and the foundation needs to be reinforced before adjustment.
3. When adding shim, you should choose materials with good wear resistance and moderate hardness.
4. After the adjustment is completed, it is necessary to measure whether the levelness reaches the standard and carry out lubrication protection.
In this paper, the horizontal adjustment skills of guide rail are explained in detail, and the principle, steps and matters needing attention of adjustment are expounded respectively, providing practical adjustment methods for everyone. After adjustment, lubrication protection should be done in daily maintenance to ensure the normal operation of the guide rail.
