One end of a reflecting mirror body 9 is connected with one end of a sleeve barrel 8 of a CCD camera 3, and the reflecting mirror body 9 is provided with a plane reflecting mirror 1 and a light source 3. The other end of the sleeve barrel 8 is connected with one end of a measuring head main body 5, and the other end of the measuring head main body 5 is connected with a guide rod 13 which is provided with a groove. A spring 6, a sliding barrel 7 and a centering shaft 4 arranged in the measuring head main body 5. The guide rod 13 which is provided with the groove is positioned in a V-shaped groove of a straight-moving round wheel 16. The utility model has the characteristics of simple and compact structure, convenient installation and maintenance, visual and simple operation, good measuring accuracy, good repeatability, good stability, etc; in addition, the requirement of the external condition is not high when the utility model is used.

Description

Thorax quality detection device in the deep hole

The utility model relates to a kind of pick-up unit, especially thorax quality detection device in the deep hole.

At present thorax wall quality in the deep hole (as taking off chromium, pit, tubercle, scar, non-metallic inclusion) is detected, the normal optics defectoscope that adopts, promptly thorax wall in the deep hole is carried out Direct observation by telescopic system, be to utilize light source to illuminate interior thorax wall, the reflected light of interior thorax wall is collected, assembled through optical system, and is observed by human eye.Because the restriction of optical system, each scope of observing is limited, also exists human eye Direct observation fatiguability, inefficiency, and function singleness can only be observed, and qualitative minute property can not be carried out detection by quantitative; Exist the testing staff to require special training simultaneously, judge that testing result varies with each individual, be unfavorable for doing weak points such as objective comparative analysis.Also there is the fiber optic image transmission technology to peep thorax, but, causes picture resolution lower, can not satisfy actual needs because the pixel of integrated optical beam is limited.

The purpose of this utility model provides a kind of simple in structure, and is easy to install, and the internal thorax wall quality of energy is made the interior thorax quality detection device of deep hole of objective analysis.

The purpose of this utility model is to realize like this, by peeping thorax mechanism, gear train is formed, its interior end of the catoptron body that is cylinder of peeping thorax mechanism is equipped with and axial line plane mirror at an angle, the other end has light source, the end that the sleeve of CCD camera is arranged in the catoptron body connecting cylinder, the other end of sleeve is connected with an end of cylindrical circular gauge head main body, the other end of gauge head main body is connected with the guide rod of the band groove of gear train, in the gauge head main body cylinder spring is housed, the flat end of slide cartridge that a both ends of the spring and an end are tapering is adjacent, slide cartridge is tapering and partly contacts the centration axis of passing the gauge head main body, the driving wheel of craspedodrome motor and follower engagement, the axle of follower is gone up the craspedodrome circle wheel that device has V-shaped groove, the guide rod of band groove is placed in the V-shaped groove of the circle wheel of keeping straight on, the swing pinion of electric rotating machine and driven gear engagement, the other circle wheel that the band pin-and-hole is arranged of driven gear, the pin-and-hole of circle wheel is equipped with register pin, and register pin is inserted in the groove of the guide rod of being with groove.

When using the utility model, in advance plane mirror is contained on the catoptron body, connects light source, CCD camera connecting line, make light source energising illumination, make the interior thorax quality of deep hole reflex to the CCD camera, then taking the photograph situation is delivered to computing machine, for its processing through plane mirror.Advancing or rotate of the guide rod of band groove sent by computing machine and referred to the present and operation, and craspedodrome motor rotation and drive driving wheel, follower and the rotation of craspedodrome circle wheel is placed on the guide rod of the interior band groove of the V-shaped groove of the circle wheel of keeping straight on and does the craspedodrome Working motion; Electric rotating machine rotates and the circle wheel of driven rotary gear, driven gear and band pin-and-hole, and register pin is rotation simultaneously also, also forces the guide rod of band groove to rotate.Centration axis head end thorax wall in the deep hole slides, and promote centration axis with the variation of thorax wall in the deep hole and move, and the other end of centration axis promotes slide cartridge, by means of the spring adjustment, makes the guide rod of band groove be positioned at the center of deep hole thorax all the time, is beneficial to detection.

The utility model has simple and compact for structurely, and installation and maintenance are convenient, operate intuitively easyly, and conditional request is not high to external world, measuring accuracy, repeatability and stable characteristics such as better.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is the thorax mechanism structure cross-sectional schematic of peeping of the present utility model;

Fig. 2 is a gear train structural representation of the present utility model;

Fig. 3 is that the A-A of Fig. 2 is to looking synoptic diagram;

Fig. 4 is that the B-B of Fig. 2 is to looking synoptic diagram.

Among the figure: the guide rod 15-driven gear 16-craspedodrome circle wheel 17-follower 18-driving wheel 19-register pin of 1-plane mirror 2-light source 3-CCD camera 4-centration axis 5-gauge head main body 6-spring 7-slide cartridge 8-sleeve 9-catoptron body 10-craspedodrome motor 11-swing pinion 12-electric rotating machine 13-band groove

As shown in Figure 1, the catoptron body 9-end that plane mirror 1 and light source 2 are housed joins with the sleeve 8 that CCD camera 3 is housed, the other end of sleeve 8 joins with gauge head main body 5 one ends that centration axis 4, spring 6, slide cartridge 7 are housed, and the other end of gauge head main body 5 joins with the guide rod 13 of band groove.

Fig. 2, the swing pinion 11 of electric rotating machine 12 and driven gear 15 engagements, driven gear 15 is connected with the circle wheel of band pin-and-hole, register pin 19 inserts in the groove of the guide rod 13 that arrives the band groove in the round pin-and-hole of taking turns, the driving wheel 18 of craspedodrome motor 10 and follower 17 engagements, the axle of follower 17 are equipped with the guide rod 13 that is placed with the band groove in the V-shaped groove of the circle wheel 16 of keeping straight on.
