Description

TECHNICAL FIELD

[0001] The utility model relates to a device for precisely measuring the levelness of a plate straightening machine roller belongs to plate straightening machine maintenance equipment technical field. BACKGROUND

[0002] The plate straightening machine roller is composed of multiple groups of working rollers and multiple groups of supporting rollers, and the assembly precision of the levelness thereof is required to be high, for example, the levelness between the multiple groups of supporting rollers is less than 0.12 mm, and the levelness between the multiple groups of working rollers is less than 0.15 mm. The assembly precision of the levelness has a great influence on the service life of the straightening machine roller. If the levelness of the supporting roller or the working roller of the straightening machine roller exceeds the limit, the relative elevation difference is large, which can cause the supporting roller or the working roller of the straightening machine to be unevenly stressed when straightening the steel plate, so that part of the supporting roller or the working roller is stressed more, part of the supporting roller or the working roller is not stressed, and thus the roller surface, bearing and transmission system of the roller stressed more are prone to damage, which can cause the straightening machine to be unable to be normally used. Meanwhile, the levelness exceeding the limit has a certain influence on the stress release of the straightened steel plate, the plate shape, the surface of the steel plate and the mechanical properties.

[0003] At present, when measuring the levelness of the plate straightening machine roller, a level gauge is usually used for measurement, that is, the level gauge scale is manually held, and the measurement is performed by reading the level gauge. Since the number of measurement points is large, the level gauge scale cannot be guaranteed to be in contact with the highest point of the roller surface at each measurement, the stability of the level gauge scale cannot be guaranteed, that is, the level gauge scale cannot be guaranteed to be in the same vertical state, there is a certain deviation, the labor intensity of personnel is large, the measurement work efficiency is low, there is a reading deviation of the level gauge, and finally the measurement result is affected. Meanwhile, since the opening degree of the upper and lower rollers of the straightening machine after being mounted is small, the space is limited and the working environment is complex, the level gauge scale cannot be put into the upper and lower rollers, the level gauge cannot be read, that is, the level gauge scale cannot be used for online measurement of the upper and lower rollers. In addition, there are many interference objects such as the outer oil pipe, water pipe and equipment spare parts of the straightening machine roller, which shield the light path of the level gauge and cause the level gauge to be unable to be read.

[0004] In addition to the level gauge measurement, there is currently a professional intelligent levelness measuring instrument. These measuring instruments generally use laser or infrared measurement, and the main disadvantage is that they cannot be measured after being shielded, and the cost of the instrument is high and needs to be operated by a special person.

[0005] Therefore, the current measurement process of the levelness of the plate straightening machine roller is complicated and has a large error, and the levelness of the roller on the machine cannot be measured. Without levelness measurement, the inclination degree of the roller with respect to the horizontal line cannot be determined, accurate measurement and adjustment cannot be performed, assembly precision cannot be guaranteed, online levelness after the roller is worn after being used for a period of time cannot be confirmed, the on-machine state cannot be evaluated, the service life of the plate straightening machine roller is affected, and the problem of the levelness measurement of the plate straightening machine roller needs to be solved.

[0055] Firstly, the number of components such as the sliding block 2, the measuring arm 3 and the dial gauge 4 is determined according to the number of roll surfaces of the measuring assembly, and the components are pre-installed in the middle part of the measuring base frame 1. The fixed support 5 and the sliding block 2 are pre-installed at the two ends of the measuring base frame 1.

[0056] If the fixed support 5 is placed on the roll surface:

[0057] ①The fixed support 5 is placed on the roll surface at the two ends, the position of the measuring base frame 1 is adjusted to make it in a horizontal state, and the locking bolts 7 between the fixed support 5 and the sliding block 2 and between the sliding block 2 and the measuring base frame 1 are locked.
