Description

Thorax inner diameter measuring device in the deep hole

The utility model relates to a kind of measurement mechanism, especially thorax inner diameter measuring device in the deep hole.

The interior thorax internal diameter of measurement deep hole adopts the light source defectoscope is arranged at present, promptly by telescopic system the deep hole internal chamber wall is carried out Direct observation, is to utilize light source to illuminate interior thorax wall, and the reflected light of interior thorax wall is through light-source system collection, convergence, and is observed by human eye.Because the restriction of light-source system, each scope of observing is limited, also exists human eye Direct observation fatiguability, inefficiency, and function singleness can only be observed, and qualitative analysis can not be carried out quantitative measurment; Simultaneously the testing staff is required special training, judge that testing result varies with each individual, be unfavorable for doing weak points such as objective comparative analysis.The mechanical star gauge of employing is also arranged, grating caliper and optical reflective star caliper etc.The grating caliper exists the requirement of grating sensor tighter, and grating ruling must be evenly, and relatively difficulty must accurately be adjusted in the installation site, and shock resistance is poor, weak points such as user's competency profiling height.The optical reflective star caliper belongs to visual optical instrument, must observe by eyepiece, reading, also exists and can only observe use for a people, deficiencies such as people's eyes tire easily.

The purpose of this utility model provides a kind of simple in structure, and is easy to install, and can be effectively internally thorax wall internal diameter make thorax inner diameter measuring device in the deep hole of quantitative measurment.

The purpose of this utility model is so real hole, by calibrating mechanism, gear train is formed, its interior device of body tube of calibrating of calibrating mechanism is calibrated pawl, there is axle hinged in the middle of calibrating pawl, there are spring and arm that the contact of calibrating of trough of belt is arranged between the galianconism end outward, calibrate contact pass calibrate external, calibrate the body cephalic par and be installed with gib screw, the gib screw bottom is in calibrating the groove of contact, calibrate the body other end light source is arranged, and an end of the sleeve of CCD camera arranged in the 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, connect light source, CCD camera connecting line in advance, make light source energising illumination, calibrate on the land that contact is stuck in thorax in the deep hole, when being with the guide rod motion operation of groove, thorax wall internal diameter varies in the deep hole is calibrated pawl through calibrating the contact extruding, the variation that to be calibrated pawl by the CCD camera passes to computing machine, for its processing.The advancing or rotate of the guide rod of band groove, sent by computing machine and refer to the present and operation, the craspedodrome motor rotates and drive driving wheel, follower and the rotation of craspedodrome circle wheel, be placed on the guide rod of the band groove in the round V-shaped groove of taking turns of keeping straight on and do the craspedodrome Working motion, electric rotating machine rotates and the circle wheel of driven rotary gear, driven gear and band pin-and-hole, register pin is rotation simultaneously also, also forces the guide rod rotation of band groove.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, transfers cover by means of spring, makes the guide rod of band groove be positioned at the center of deep hole thorax all the time, is beneficial to measurement.

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.
