Abstract

The utility model relates to an incense coil type filament X-ray ceramic tube used for an industrial diagnostic machine and comprising a ceramic tube sleeve, the upper portion of which is provided with a cathode assembly through an outer ring sleeve; the upper end of the cathode assembly is provided with an air duct extending to the external of the ceramic tube sleeve, and the lower end of the cathode assembly is provided with a focusing head placed in the ceramic tube sleeve; a groove is provided in the focusing head; the groove bottom is provided with a cathode filament aperture, the inner of which is filled with a cathode filament; the lower end of the ceramic tube sleeve is provided with a flange plate equipped with an anode assembly; the ceramic tube is characterized in that the cathode filament aperture provided on the focusing head is a circular through hole in which an incense coil type cathode filament is provided. The incense coil type filament X-ray ceramic tube solves the problem that for an existing linear type filament X-ray ceramic tube, the filament is easy to deform when heated, and the radiation field is not uniform, which may influence product quality. The incense coil type filament X-ray ceramic tube is mainly used for the X-ray ceramic tube of a portable industrial diagnostic machine.

Description

A kind of incense coil type filament X ray earthenware

The (1) technical field: the utility model relates to the critical piece that uses on the industrial flaw detection machine, especially a kind of incense coil type filament X ray earthenware.

The (2) background technology: because existing X ray earthenware exists certain defective, particularly bore the target circumferential tubes and exist the uneven defective of radiation field, all the time, circumferential tubes is an emitter with the linear pattern coiled filament all; And awl target pipe is tapered, and linear pattern filament electrons emitted is beaten at target surface, can produce deviation; If filament is not straight, or because of adding the electric current temperature distortion, or uses because of filament is long-term and to be out of shape; Can cause radiation field inhomogeneous, thereby influence the quality of equipment, use linear pattern filament production awl target earthenware in addition; Inhomogeneous because of radiation field, also can cause rate of finished products not high, probably have only about 60%.

The (3) summary of the invention: the purpose of the utility model will solve existing X ray earthenware filament exactly and be prone to temperature distortion, and radiation field is inhomogeneous, influences the problem of product quality, and a kind of incense coil type filament X ray earthenware is provided.

The concrete scheme of the utility model: improve to existing X ray earthenware, it has ceramic pipe box, through outer ring set cathode assembly is installed on the top of ceramic pipe box; The upper end of cathode assembly is provided with the outside that wireway stretches out ceramic pipe box, and the lower end of cathode assembly is provided with the inside that focus head places ceramic pipe box, in focus head, has groove; Bottom portion of groove has the cathode filament hole; Cathode filament is housed in the hole, ring flange is installed, anode assemblies is housed on ring flange in the lower end of ceramic pipe box; The head of anode assemblies is equipped with the screen guard shield; And be equipped with on the metal in the junction of ring flange and ceramic pipe box and encircle, it is characterized in that: the cathode filament hole of offering on the said focus head is a manhole, and the cathode filament of installing in the through hole is the incense coil type.

The utility model uses filament indeformable through changing the anodic filament shape and structure for a long time, and the electronics that incense coil type filament sends can hit at target surface uniformly, and the radiation field of generation is even, has improved the qualification rate of product greatly, and qualification rate has reached about 80% basically.

The (4) description of drawings

Fig. 1 is the general structure front view of the utility model;

Fig. 2 is that the A of Fig. 1 is to zoomed-in view.

Among the figure, the 1-wireway, the outer ring set of 2-, the 3-cathode assembly, the 4-cathode filament, the 5-focus head, 6-pottery pipe box, 7-shields guard shield, encircles 9-ring flange, 10-cathode filament hole, 11-groove, 12-anode assemblies on the 8-metal.

The (5) embodiment:

Referring to Fig. 1, the utlity model has ceramic pipe box 6, through outer ring set 2 cathode assembly 3 is installed on the top of ceramic pipe box 6; The upper end of cathode assembly 3 is provided with the outside that wireway 1 stretches out ceramic pipe box 6, and the lower end of cathode assembly 3 is provided with the inside that focus head 5 places ceramic pipe box 6, in focus head 5, has groove 11; Groove 11 bottoms have cathode filament hole 10, and cathode filament 4 is housed in the hole, in the lower end of ceramic pipe box 6 ring flange 9 are installed; Anode assemblies 12 is housed on ring flange 9, and the head of anode assemblies 12 is equipped with screen guard shield 7, and is equipped with the junction of ceramic pipe box 6 at ring flange 9 and encircles 8 on the metal; Particularly: the cathode filament hole of offering on the said focus head 5 10 is manhole; The cathode filament of installing in the through hole 4 is the incense coil type, and promptly the coiling structure with coiled mosquito-repellent incense is identical, referring to Fig. 2.
