Detailed Description

As shown in fig. 1-5, a device for high-precision and rapid adjustment of parallelism of multiple rollers comprises a support 1 arranged at two ends of one side of production line equipment, wherein a reference line 2 is arranged on the support 1, and the reference line 2 is parallel to the central line of the production line equipment. The alignment tool 3 is columnar and is detachably mounted at the end of the roller 4 through a bolt 11, and in the rotating process of the roller 4, the alignment tool 3 can rotate along with the rotation of the roller 4. And a scriber 5 or an inner micrometer 6 is arranged at the other end of the alignment tool 3, and the scriber 5 is a metal scriber and is used for roughly estimating the horizontal distance between the metal scriber and the datum line 2. A vertical line 7 is correspondingly arranged at the lower end of the datum line 2, and the vertical line 7 is connected with a hanging hammer 8. The inside micrometer 6 is used to accurately measure the horizontal distance between the inside micrometer 6 and the perpendicular line 7.

And steel plates are fixed on the ground below the support 1 at the two ends of one side of the production line equipment, and reference points 9 are carved on the steel plates. The reference point 9 facilitates the adjustment of the reference line 2.

The datum line 2 is a steel wire, one end of the datum line is connected with the support 1, and the other end of the datum line is stretched through free sagging of the tensioning weight 10. This ensures that the reference line 2 is always in tension.

The end of the alignment tool 3 is provided with a hole, and the bolt 11 penetrates through the hole in the alignment tool 3 and then is in threaded connection and locking with a threaded hole in the end of the roller 4. Therefore, the disassembly and the assembly are convenient and quick.

The drop hammer 8 is placed in an open cup 12 containing liquid. Thereby ensuring that the drop weight 8 does not rock left or right.

The working principle and the process are as follows:

1) and after the equipment is adjusted and fixed, finding the central line of the whole production line, and fixing the central line at one end of the production line by using a steel wire with the diameter of 1.5 mm.

2) On the basis of the center line, two proper datum points 9 are found on the ground at the head and tail positions of one side of the production line equipment by using a roll size and a high-precision level gauge, two steel plates are fixed on the ground by using expansion bolts, the two datum points 9 are carved on the steel plates and used as a permanent datum of the whole production line, and the precision of the roller is adjusted for later installation and maintenance.

3) The method comprises the following steps of finding a steel wire with the diameter of 1.5mm and the length of about 70m, manufacturing two supports 1 beside two ground benchmarks, supporting the steel wire on the supports 1, using a solid wire hanging hammer to align the steel wire benchmarks through a method of aligning center datum points for multiple times, ensuring the steel wire benchmarks to be parallel to the center of equipment, fixing one end of the steel wire, tensioning the steel wire by using a heavy object hung at the other end of the steel wire, and using the steel wire as a datum line 2 for adjusting the parallelism of a cleaning wire roller.

3) In the whole cleaning line, the roller 4 is up to 40 in quantity, and divide into upper and lower two-layer, before the adjustment depth of parallelism, need to control every layer of roller difference in height within 0.5mm, utilize high accuracy spirit level and 1m steel plate chi for the engineering, earlier with the spirit level after the rigidity in suitable position, utilize the scale on the steel plate chi, read the high numerical value of two-layer roller respectively, through the height position of adjustment roller both ends bearing frame, pass through the cooperation of high accuracy spirit level simultaneously, guarantee that the straightness accuracy of roller is within 0.002mm, the difference in height of each roller is within 0.5mm, numerical value fixed back, locking roller both ends height adjusting bolt.

4) As shown in fig. 2 and 5, the parallelism of each roller 4 is roughly adjusted, the alignment tool 3 is manufactured by utilizing the technical threaded holes on the upper end surface of each roller 4, the alignment tool 3 is fixed on the roller 4 by bolts, the rollers 4 are rotated by 180 degrees on the left side and the right side, and the alignment tool 3 rotates along with the rollers 4. The size of the gap between the scriber 5 and the reference line 2 (steel wire) on the viewing tool is adjusted, and the left and right positions of bearing seats at the two ends of the roller are adjusted, so that the gap between the scriber 5 and the reference line 2 is basically consistent.

5) The parallelism of each roller is finely adjusted, a metal scriber on the alignment tool 3 is taken down, the inside micrometer 6 is replaced and fixed, a vertical line 7 (cotton thread) is tied on the datum line 2 (steel wire thread), the tail part of the vertical line 7 is a hanging hammer 8, the hanging hammer 8 is immersed in an open cup 12 filled with engine oil, and therefore in order to reduce the random swing of the datum line 2 in the measuring process, the measuring efficiency and the measuring precision are improved. The alignment fixture 3 is swung leftwards or rightwards according to the position of the perpendicular line 7 (leftwards swing in fig. 3), the inner micrometer 6 is swung to the position of the perpendicular line 7, and the gap value between the inner micrometer 6 and the perpendicular line 7 is read. By setting, when the clearance between the inside micrometer 6 and the perpendicular line 7 is 0, the parallelism of the roller 4 is 0, that is, it is. Other gap values reflect the deflection of the roller, with smaller readings indicating smaller parallelism values. And when the gap value is larger, the left and right positions of the bearing seat are adjusted, the parallelism of each roller is ensured to be within 0.002-0.004mm, the parallelism value of each roller is recorded, and finally the locking bolt is fixed.

6) And the metal strip passing through the production line runs at a high speed, and whether the strip deviates is checked to detect whether the parallelism is adjusted in place.

7) Maintenance, servicing and replacement of the rollers during production runs are carried out in accordance with the method described above.
