Description
Technical field
The present invention relates to a kind of method monitoring medical bracket pipe diameter change.
Background technology
Along with the fast development of material science and super micro-processing technology, Medical rack material category gets more and more, and compares the nonmetallic materials such as metal materials such as common are Stainless steel 316 L, Nitinol, cobalt-base alloys, pure iron, magnesium alloy, and macromolecule.The generation of blocking and causing various sufferer is even caused to stop vessel retraction because Medical rack plays hemangiectasis wall in the blood vessel, requiring on support on each muscle feature structural dimension parameter one to show keeps tension force on whole support each point identical, and this proposes requirements at the higher level to Medical rack processing technology.General Medical rack all adopts seamless tubular goods to process, because insertion type operation is not comprehensive in global evolution, medical material technical development is also unbalanced, at present in the world to the technical standard that the tubing being used as Medical rack is comparatively ununified, and generally specified according to correlation experience oneself by Medical rack research institution or support manufacturer, Medical rack tubing provider provides respective holder according to these regulations.Consider that Medical rack seamless tubular goods adopts the technological method for processing such as drawing to produce, because the defect of technique must be difficult to ensure caliber tolerance homogeneity on whole (general length can more than 2 meters) support tubing.And the support tubing caliber tolerance entirety of giving Medical rack manufacturer needs to control within the scope of ± 10um, in fact due to processing and context of detection technical deficiency, inevitably even overproof problem is changed greatly at the difference place caliber of whole support tubing.
Because there be certainly existing of the problems referred to above, carry out in support laser cutting process in rear end, the selection needs of frock clamp and tubing caliber and tolerance match, otherwise the strut width consistance tolerance etc. finally cut out can be caused to be difficult to meet design requirement.And once for after this standard caliber matches frock clamp in support laser process equipment, but because on tubing, indivedual Position Pipe footpaths tolerance variation exceeds specialized range, tubing then can be caused stuck by frock clamp in fill process, and then electric rotating machine and linear electric motors momentary load may be caused to increase, electric current increases, motor overheating itself, if long-time unmanned discovery, may cause motor to burn out.In addition, if be stuck in cutting process, laser may gone out always, cause security risk.Therefore, before support cut, the caliber of Medical rack tubing must be monitored.
The method being conventionally used to monitoring Medical rack tubing is before the non-material loading of Medical rack tubing, the each several caliber data in two ends and centre of whole support are measured one by one with spiral dial gauge, if meet about this standard caliber tolerance, namely think that this support tubing can meet the demands, can material loading be carried out.This measuring method is owing to being operate before non-material loading, and be contact type measurement, bending and survey instrument may be caused directly to contact with tube material and tube wall cause support outer pipe wall to damage to support tubing in measuring process and cause and scrap, and Medical rack tubing is expensive, bring larger cost pressure will inevitably to support manufacturer.In addition, because whole support tubing is very long, adopt this measuring method obviously can only carry out some sections of measurements on whole support tubing, cause and be difficult to evade completely when to cause charging because local caliber is overproof by the stuck risk brought of frock clamp.
The present invention discloses a kind of On-line Measuring Method monitoring medical bracket pipe diameter tolerance change, the method does not need to carry out independent caliber tolerance measurement before the charging of Medical rack tubing, in order to avoid cause the unnecessary damage of support tubing in this link, directly by support tubing clamping in support laser cutting device, by equipped with non-contact precision feeler between support cutting zone and gripping section, carry out limit processing limit on-line measurement, the each section caliber of real-time measurement support tubing and tolerance variation, once there be off-gage phenomenon to occur, measuring system is by automatic alarm, after reporting to the police, feed shaft will stop no longer continuing charging automatically, evade completely and continued charging because caliber is overproof and cause the situation by rear end frock clamp is stuck to occur.
Summary of the invention
Technical matters to be solved by this invention is that Medical rack pipe adopts contact type measurement to cause survey instrument and support frequently to contact to cause vessel wall damage and continue charging because medical bracket pipe diameter is overproof causing by the stuck problem of rear end frock clamp, the invention provides a kind of new Medical rack pipe caliber method for automatic measurement, the method adopts correlation gauge head to measure support tubing caliber, avoids contact type measurement instrument to bring to tube wall because of frequent to contact with support tubing and damages and continue because medical bracket pipe diameter is overproof charging and cause by rear end frock clamp stuck.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of method monitoring medical bracket pipe diameter change, device therefor comprises measuring equipment and watch-dog, described measuring equipment, be made up of measuring table and charging supporting module, described measuring table is fixed with measurement shafting system, described measurement shafting system comprises turning axle, measuring equipment control system is set below measuring table, automatic feed clamping device described measuring table is equipped with, stationary shaft, linear axis, turning axle and correlation gauge head, described charging clamping device has bush hole, the described measuring table left and right sides is provided with charging supporting module, there is in correlation gauge head signal generator and signal receiver,
