For achieving the above object, the utility model proposes a kind of exposure support for small diameter tube circumference ray detection, comprise support bar, arc support, corrosion resistant plate, steel plate flanging, hook rack; The quantity of described support bar is 4, is provided with arc support between adjacent supports bar, the distribution of 90 °, support bar interval, and arc support surrounds circle; The circular central place that described arc support surrounds is provided with circumferential X-ray production apparatus; Described arc support comprises arc upper bracket and arc lower carriage, is provided with several corrosion resistant plates between arc upper bracket and arc lower carriage, and corrosion resistant plate interval is arranged; Described arc upper bracket is provided with several hook rack, and hook rack is positioned at inside corrosion resistant plate, is provided with bracket bottom hook rack, bracket is placed with tested pipe fitting.
As preferably, the quantity of described arc support is 4, and the quantity of corrosion resistant plate is 20, and the quantity of each arc support being installed corrosion resistant plate is 5 pieces.
As preferably, be provided with steel plate flanging inside described corrosion resistant plate, steel plate flanging is arranged on left and right, the downside of corrosion resistant plate, places film in steel plate flanging.
As preferably, be provided with fixed orifice bottom described support bar, support bar top is provided with groove, and support bar is installed fixing by fixed orifice, groove and arc support.
As preferably, described groove is strip, and arc support moves up and down in groove.
As preferably, be provided with base bottom described tested pipe fitting, base is placed on bracket.
The beneficial effects of the utility model: the utility model can carry out the ray detection of 20 workpiece by the making of this frock simultaneously, substantially increases work efficiency.Each consistent by the parameter of transillumination workpiece during ray detection, the negative quality of acquisition is good, meets standard-required.Use in particularly suitable and match, fully can ensure that the match caused because characterization processes is inconsistent is unfair.There is no the auxiliary of instrument, when carrying out small diameter tube ray detection, in order to the requirement of transillumination technology, needing extra auxiliary appliance.The utility model can make the carrying out of small diameter tube ray detection more convenient and quicker.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
