Method for focus positioning of x-ray machine with locking handwheel

Abstract

The invention relates to a method for positioning the focus of an X-ray machine with a locking hand wheel. The method for positioning the focus of the X-ray machine with the locking hand wheel comprises the following steps that an adjustable two-leg support is installed at the front end of the X-ray machine; an adjustable single-leg support is installed at the rear end of the X-ray machine; the height and the separation angle of the X-ray machine are adjusted primarily; the X-ray machine is placed in a positioned mode in the ray bundle direction required by the technique according to the focal length required by the technique, and it is judged that the focal length meets the requirements through visual inspection at the same time; the adjustable double-leg support and the adjustable single-leg support are measured, positioned and adjusted according to the central exposure method and the eccentric exposure method till the positioning precision meets the detection technological requirements, and then focus positioning is completed. The method for positioning the focus of the X-ray machine with the locking hand wheel has the advantages that operation is easy, the method is scientific and reasonable, cost is low, time for adjusting the X-ray machine is shortened, focus positioning is convenient and fast, and working efficiency is improved.

Description

[0001] This application is a divisional application with the patent application number 201310084211.3, the patent name is a method for positioning the focus of an X-ray machine by using an adjustable bracket, and the filing date is 2013.03.15. technical field [0002] The invention belongs to the field of X-ray machines, in particular to a method for positioning the focus of an X-ray machine with a locking hand wheel. Background technique [0003] At present, when the X-ray machine detects the ring and longitudinal welds of the cylindrical container, due to the requirements of the focal length and angle of the transmitted radiation, it is necessary to fix and accurately adjust the position of the X-ray machine and locate the focus. In terms of the fixation and adjustment of the previous X-ray machine, the newly-manufactured cylindrical container is generally carried out by means of rope hanging by welding temporary hooks, adjustment and fixation of the adjustment machine, or ...

AI Technical Summary

Problems solved by technology

The way of fixing the temporary hook on the top not only causes damage to the base material, but also increases the workload of welding and removing the temporary hook. At the same time, when it is adjusted and fixed, it requires personnel to climb to the top of the cylinder or two people to carry the ray machine inside the cylinder The danger is increased with factors such as the rotation of the tire; although it is more convenient to fix and adjust the adjustment machine in the transillumination room, it can only perform a single transillumination with the source outside. In addition, the device is heavy and moves slowly, which makes the transillumination efficiency lower; setting up temporary support and fixing requires a large number of supporting members and auxiliary personnel to set up the support, the workload is large and generally cannot fully meet the requirements of accuracy and efficiency; and although the temporary support sticks used in the past are tied with iron wires, it is convenient to enter and exit the closed container. The above problems can also be solved without being restricted by other factors, but the adjustment efficiency is still low, the stability is poor, the adjustment accuracy is not high, and continuous adjustment in a fixed state cannot be performed.
