Description
Technical Field
The utility model belongs to the technical field of measuring instruments, and particularly relates to a support device for calibrating an X-ray thickness gauge, which is a matching component of the thickness gauge of a production line of a cold rolling mill unit and is suitable for measuring thickness calibration of the X-ray thickness gauge.
Background
At present, all thickness gauges on the production line of a cold rolling unit adopt an on-line detection device to measure the actual thickness of a strip steel in the rolling process. The thickness gauge structure is substantially the same as the cast-rolled aluminum coil plate online X-ray thickness measuring device disclosed in patent No. 2018203928133. The thickness gauge main body is a C-shaped frame, an X-ray emitter is arranged at one end of the lower portion of the C-shaped frame, and an X-ray receiver is arranged at one end of the upper portion of the C-shaped frame. The X-ray emitter and the X-ray receiver are symmetrically arranged, and the lower part of the C-shaped frame is provided with a circular X-ray emitting hole corresponding to the position of an emitting head of the X-ray emitter.
The thickness gauge changes the pressing position, tension or motor rotating speed of the rolling mill by means of a closed loop control circuit and PLC calculation according to a deviation signal obtained by comparing an actual measured value with a set value, and controls the thickness within an allowable deviation range, so that the measurement accuracy and the measurement stability of the thickness gauge are very important for the thickness control of the cold rolling mill set. However, as the time of use of the equipment increases and the equipment wears out daily, the measurement accuracy becomes lower and lower, and the calibration needs to be performed by using a standard thickness template. The thickness of the thickness sample plate is known and the caliper offset is determined by comparing the values measured by the caliper to the values measured by the caliper.
However, the existing thickness gauge has no device for placing the thickness sample plate, the surface of the C-shaped frame is uneven due to abrasion after the thickness gauge is used for a long time, the thickness of the thickness sample plate is usually within 0.2-2cm, the thickness sample plate is greatly influenced by errors, and the calibration rule of directly placing the thickness sample plate on the C-shaped frame cannot be accurately calibrated.
