Laser cutting machine mechanical correction method. As one of the fastest growing metal cutting equipments in recent years, laser cutting machines have been widely welcomed in various industries.
Then after long-term use of laser cutting, the mechanical system displacement will occur more or less, resulting in a decrease in cutting quality and equipment accuracy.
And it is especially important to regularly calibrate the mechanical system. The degree of correction of the mechanical system will directly affect the effect of the product.
Then the two axes of the shaft are not parallel to the direction of the correction axis.
And the laser is polish until the spots on both ends of the shaft are consistent; then the laser head is moved to the proximal end of the shaft; the light is back and forth in the axial direction until the X-axis is remote and proximal.
The spot is uniform in the up and down direction; then the laser head is respectively illuminated at the four corners of the table to determine whether the spot in the lower right corner is consistent with the other three spots; the spot in the lower right corner is upward.
First loosen the four screws between the aluminum and the fixed block under the left rail (ie the large screws at the ends of the rail), add a small piece of iron between the aluminum material at the lower left corner and the fixed block to raise the aluminum and tighten the screws.
Repeat 1 step to check whether the spot is consistent; if low, add a small piece of iron, repeat 3, (step, until the four spots are consistent. Place a plate of the same size as the table on the table. And put a small square about 5mm on it.
1. Move the laser head to an angular position on the table. Move the nozzle up and down to the surface of the small square, then move the laser head to the other three corners of the table.
And test the distance between the nozzle and the plate with small squares, such as high or low. The same, find the lowest one of the corners as the benchmark;
2. Loosen the screws that fix the table top, and then slowly knock down the table top at the screw position.
Then move the laser head to the position, test the distance between the nozzle and the plate with a small square. If it is not the same, continue to knock down.
And test its height until the height of the place is the same as the reference point.
3. Move the laser head to another location and repeat step 2 until the height of the entire table is the same as the reference point.
Tighten all the screws used to secure the table. Straight angle adjustment, cut a rectangle of the same size on a flat plate or cardboard, measure its diagonal line.
The line from the upper right corner of the A line to the bottom left corner.
And the line from the upper left corner to the lower right corner of the B line is subject to the B line.
If the A line is longer than 3MM, the timing belt in the Y-axis direction of the right side of the machine will be relax.
And the corresponding belt teeth will make the horizontal amount downward. Then tighten the belt and adjust the optical path to within 3MM.
