Description
Technical Field
The invention relates to a method for improving the stability of a standard sample box of a thickness gauge.
Background
The X-ray thickness gauge undertakes the task of measuring the thickness of the steel plate on line and sends the measured data to the upper-level L2 control system, and the system calculates the thickness and the rolling model of the steel plate and plays a vital role in improving the product quality since the medium and heavy plates of the rolling mill of the eight steel works company are put into operation. However, after continuous uninterrupted operation, the faults of the thickness gauge system are increased gradually, and the compensation calculation of the L2 model on the thickness is directly influenced, so that the thickness of the plate blank is out of tolerance, and the product quality is influenced. Therefore, through careful analysis of various subsystems and control software of the thickness gauge, fault points are gradually concentrated on the standard sample box. After the standard sample box is disassembled, the rocker arm movement mechanism in the standard sample box is seriously abraded, and the movable joint part even has the falling phenomenon, so that the rocker arm can not drive the standard sample wafer to reach the emission window of the X-ray, and finally the calibration failure of the thickness gauge is caused. Frequent movement and severe abrasion of the rocker arm movement mechanism during sample piece calibration are important reasons that the thickness gauge cannot work normally. And (3) searching documents: (1) masilsafe, shenfei, a high performance microfocus X-ray thickness gauge patent, 8 months in 2018; (2) zhang Xiaochun, application of X-ray thickness gauge in hot-rolled plate strip, automatic gauge 2014 for 2 months; (3) the application of Li Jiangyong and Li Xin RM215 series single-point X-ray thickness gauge in eight-steel medium and heavy plates is reported by networks in 2012. From the above searched documents, there is no application technology that can improve the stability of the rocker arm and optimize the control strategy thereof in the method for improving the working stability of the standard sample box of the X-ray thickness gauge.
Disclosure of Invention
The invention aims to provide a method for improving the stability of a standard sample box of a thickness gauge, which can thoroughly solve the equipment hidden trouble of the standard sample box of the thickness gauge, improve the stability of the standard sample box and prolong the service life of the standard sample box.
The technical scheme of the invention is that the method for improving the stability of the standard sample box of the thickness gauge comprises a rocker arm A and a rocker arm B which are arranged on a rocker arm cylinder in the standard sample box, wherein a red copper sleeve with the outer diameter of 8mm, the inner diameter of 6mm and the height of 3.5mm is embedded in a hole with the diameter of 8mm at the front end of the rocker arm B; a brass copper sleeve with the outer diameter of phi 6mm and the inner diameter of phi 5mm and the height of 3.5mm is embedded in a hole with the diameter of phi 6mm at the rear part of the rocker arm A; a phi 5mm bolt penetrates through the copper sleeve to connect the two rocker arms; the action of the rocker arm cylinder is controlled by a PLC (programmable logic controller), and the interlocking conditions are as follows: when steel rolling is carried out normally, the thicknesses of steel plate incoming materials are compared, zero calibration is only carried out once if the thicknesses of the steel plates are consistent, and zero calibration is carried out once for each block if the thicknesses of the steel plates are inconsistent; when the calibration is complete, the rocker arm is controlled by the thickness gauge; when the thickness exceeds the measuring range of the thickness gauge, zero calibration is not carried out.
The rocker arm shaft adopts two copper sleeves made of different materials and different diameters to be mutually nested to replace the original connecting piece, the screw rod penetrates through the two copper sleeves to fix the copper sleeves, and the rocker arm shaft can freely and flexibly move. The method thoroughly solves the equipment hidden trouble of the standard sample box of the thickness gauge by the measures, improves the stability of the standard sample box, improves the fault rate of the standard sample box from 1 time per 2 months to 1 time per 2 years, and has no fault that the movable joint falls off so far! Through the implementation of the measures, the measurement precision of the thickness gauge is fundamentally ensured, the maintenance cost is reduced, and the production efficiency is improved. The method is suitable for all similar X-ray thickness measuring instrument standard sample boxes, has no special limitation, and has strong popularization and application prospects.

Detailed Description
A method for improving the stability of a thickness gauge sample box comprises a rocker arm A1 and a rocker arm B5 which are arranged on a rocker arm cylinder in the sample box, wherein a red copper sleeve 2 with the outer diameter phi 8mm, the inner diameter phi 6mm and the height of 3.5mm is embedded in a hole with the front end diameter phi 8mm of the rocker arm B5; a brass copper sleeve 3 with the outer diameter of phi 6mm, the inner diameter of phi 5mm and the height of 3.5mm is embedded in a hole with the diameter of phi 6mm at the rear part of the rocker arm A1; the two rocker arms 1, 5 are connected by a phi 5mm bolt 4 through the copper sleeves 3, 2. Thus, the two rocker arms can move freely and flexibly. When the copper bush in the moving part is worn, only the copper bush needs to be replaced, and the replacement time is greatly shortened. And the program of the PLC control standard sample box is optimized, and unnecessary action programs of the cylinder are reduced. The action of the rocker arm cylinder is controlled by a PLC (programmable logic controller), and the interlocking conditions are as follows: when steel rolling is carried out normally, the thicknesses of steel plate incoming materials are compared, zero calibration is only carried out once if the thicknesses of the steel plates are consistent, and zero calibration is carried out once for each block if the thicknesses of the steel plates are inconsistent; when the calibration is complete, the rocker arm is controlled by the thickness gauge; when the thickness exceeds the measuring range of the thickness gauge, zero calibration is not carried out.
