DETAILED DESCRIPTION

[0025] The present invention discloses a measuring tool 10, which is used to measure the gap between the upper roller and the lower roller, wherein the upper roller is located above the lower roller, and the upper roller and the lower roller are arranged horizontally, for example, to measure the gap between the upper working roller 21 and the lower working roller 23 in the tensioning and leveling machine. More specifically, on the basis of the upper roller and the lower roller, the equipment further includes an installation foundation, and the upper roller and the lower roller are connected to their respective installation foundations.

[0026] Please refer to Figure 1The measuring tool 10 disclosed in the present invention includes a main body 100 and a partition 200. The partition 200 includes a first plate portion 210 and a second plate portion 220 outside the first plate portion 210. The first plate portion 210 is defined as having a uniform thickness, that is, the thickness of the first plate portion 210 is a fixed value, and both sides of the thickness of the first plate portion 210 are straight planes. In the present invention, the main body 100 is movably connected to the second plate portion 220. When measuring the roller gap between the upper roller and the lower roller, the main body 100 is fixedly installed on the installation base connected to the lower roller, and the first plate portion 210 is placed on the lower roller to be measured. Under the limited condition that the main body 100 is movably connected to the second plate portion 220, the main body 100 can adjust the inclination state of the first plate portion 210 and adjust the first plate portion 210 to a horizontal state.

[0027] Please refer to Figure 2 When the first plate 210 is placed on the lower roller and the first plate 210 is adjusted to be horizontal, the distance between the first plate 210 and the upper roller can be directly and conveniently measured by a measuring instrument, and a feeler gauge can be used as the measuring instrument. The sum of the distance between the first plate 210 and the upper roller and the thickness of the first plate 210 is the roller gap between the upper roller and the lower roller at the measurement point. The measurement matching tool 10 disclosed in the present invention can quickly measure the roller gap between the upper and lower rollers, and has the advantages of simple detection, convenient disassembly and assembly, time and labor saving, and low cost.

[0028] When the measuring tooling 10 disclosed in the present invention is applied to the working rolls of the straightening machine and replaced according to the roll period, the roll gap values ​​of the upper and lower working rolls 23 in the straightening machine at both ends of the length are measured respectively, and the roll gap values ​​at both ends of the length are obtained. The difference between the two values ​​is the gap deviation at both ends of the working roll. By applying the scheme disclosed in the present invention, the gap measurement process of the two arc surfaces is transformed into the gap measurement process of the plane and the arc surface, which greatly improves the measurement accuracy. By applying the scheme disclosed in the present invention, it is possible to quickly determine whether the gap deviation at both ends of the working roll exceeds the specified range, and it can be ensured that the gap deviation at both ends of the working roll does not exceed the specified range, thereby successfully completing the replacement operation of the working roll.

[0029] After the working rolls of the straightening machine are replaced, the gap deviation at both ends of the working rolls is ensured not to exceed the specified range, which ensures the spatial accuracy of the straightening machine roll system, improves the strip edge wave problem within one maintenance cycle of the production line, avoids the problem of abnormal wear of the downstream roll surface, and thus ensures the service life of the downstream roll. After measurement using the disclosed solution, the gap deviation of the upper and lower working rolls 23 of the straightening machine is controlled within 3 wires, which solves the problem of poor strip shape at the outlet of the straightening machine, and no abnormal wear of the downstream squeeze roller occurs, which has great economic benefits.

[0030] In more possible implementations, the measuring tool 10 disclosed in the present invention can also be used in application scenarios other than the tensioning and straightening machine to accurately measure the arc surface gap between the upper and lower rollers.

[0031] In some embodiments, see Figure 1 The partition 200 is a strip plate, which includes a first plate portion 210 and a second plate portion 220 connected to the length side of the first plate portion 210. In the structural form of the strip plate, the width of the partition 200 is relatively small. When the first plate portion 210 is adjusted to a horizontal state, it is ensured that the first plate portion 210 is as close as possible to the lower roller to be measured.

The body 110 is provided with a threaded hole connected to the top screw 121, and the top end of the top screw 121 abuts against the lower edge of the second plate portion 220. Under the condition that the body 110 is connected to the mounting base connected to the lower roller and the first plate portion 210 is placed on the lower roller to be measured, by rotating the top screw 121, the protruding length of the top screw 121 on the body 110 can be adjusted, thereby achieving the adjustment of the inclination of the first plate portion 210.

[0035] In some embodiments, see Figure 1 The adjusting member further includes a lock nut 122, which is threadedly connected to the top screw 121, and the lock nut 122 can contact the upper edge of the body 110. After adjusting the first plate 210 to a horizontal state, the lock nut 122 is tightened until the lock nut 122 is in contact with the upper edge of the body 110. There is friction in the surface contact between the lock nut 122 and the body 110, and the top screw 121 can be relatively fixed by the lock nut 122.

[0036] In some embodiments, a groove is opened at the lower edge of the second plate portion 220, and the cross-section of the groove may be circular. The groove cooperates with the top end of the top screw 121, and the top end of the top screw 121 is located in the groove. During the process of adjusting the top screw 121, the groove ensures that the partition 200 will not be laterally offset relative to the top screw 121.

[0037] Regarding the measuring level instrument, the measuring level instrument is arranged corresponding to the first plate portion 210, and a level meter, a laser instrument, or other equipment may be used. When the measuring level instrument is a level meter, in specific use, the level meter may be placed on the upper edge of the first plate portion 210, or the level meter may be embedded in the first plate portion 210 and may be directly visible at the first plate portion 210.
