Description
Technical field
The present invention relates to automobile air-conditioner air door connecting rod detecting tool field, be specifically related to a kind of automobile air-conditioner air door connecting rod endoporus roundness measurement frock.
Background technology
Air conditioning for automobiles has various mode of operation, and the switching between each pattern is realized by operating system.Throttle linkage is a vitals of air conditioning mode state operating system, and in the mode manipulation system of whole air conditioning for automobiles, throttle linkage plays connection air door and the effect of operating mechanism.Extreme influence air conditioning for automobiles mode state is switched by the change of throttle linkage angle, the deflection of guide pillar and its elasticity coordinated with drive mechanism, affect air force and the uniformity of each pattern air outlet, also contribute to feel when people handle Air-Conditioning Control Panel simultaneously.
The circularity of the endoporus in throttle linkage plays an important role with coordinating of drive mechanism at throttle linkage, but the circularity of the endoporus of throttle linkage is typically with manually being detected by dial gauge.For the manufacturer of batch production throttle linkage, artificial employing centimeter check comes with some shortcomings, and on the one hand detection efficiency is low, and on the other hand, testing result accuracy rate is low.
Summary of the invention
It is an object of the invention to provide a kind of accuracy of detection high, and easy to operate automobile air-conditioner air door connecting rod endoporus roundness measurement frock.
For reaching above-mentioned purpose, the base case of the present invention is: automobile air-conditioner air door connecting rod endoporus roundness measurement frock, including flexible fastening set, rotary shaft and fixing seat, the upper end of rotary shaft is rotationally connected with flexible fastening set, and the lower end of rotary shaft is rotationally connected with fixing seat；Support seat is installed in described rotary shaft, this support seat is provided with guide cylinder, supports seat and is provided with the receiving chamber connected with guide cylinder, and this receiving intracavity is provided with shell fragment, it is provided with on this shell fragment on foil gauge, rotary shaft or support seat and the strain detector electrically connected with foil gauge is installed；Hard alloy steel ball is installed in guide cylinder, this hard alloy steel ball is less than 0.005mm with the gap of guide cylinder, shell fragment is connected by elastic component with hard alloy steel ball, when this elastic component is in force-free state, the centre of sphere of hard alloy steel ball is equal with the radius that flexible fastening is overlapped with the vertical dimension of the axial line of rotary shaft.
Hard alloy steel ball in this programme has stronger hardness and wearability, can extend the service life of detection equipment, and when hard alloy steel ball slides on the inner hole wall of throttle linkage, generates heat less.When elastic component is in force-free state, the centre of sphere of hard alloy steel ball is equal with the radius that flexible fastening is overlapped with the vertical dimension of the axial line of rotary shaft, and convenient installation makes.
Operation principle and the advantage of this programme are: when concrete this detecting tool of employing carries out endoporus detection to throttle linkage, first flexible fastening set is inserted in endoporus, now flexible fastening set is by certain deformation, flexible fastening set is tightly secured at endoporus, now the hard alloy steel ball in guide cylinder contacts with the surface of endoporus, and elastic component is in stress, shell fragment generation miniature deformation, then fixing seat is arranged in detection platform, and makes throttle linkage be in horizontal stationary state.Start strain detector, record the data on now strain detector, then slow rotary motion axle, observe the data variation on strain detector, if during rotary shaft rotates, there is bigger change in the data on strain detector, then show that the circularity of this endoporus exists bigger flaw, if the data variation on strain detector is less, then show that the circularity of this endoporus is preferable.
This endoporus roundness measurement frock, when design, is inserted in endoporus by flexible fastening set, and the elasticity utilizing flexible fastening to overlap realizes quick insertion and the purpose quickly extracted.It addition, this programme utilizes strain limit as important detection instrument, the precision of raising detection, realize data visualization by use strain detector, when reducing tradition use centimeter check, impact testing result brought because of the inaccuracy of artificial reading.When specifically installing, the most fairly simple convenience, flexible fastening set is inserted in endoporus, make fixing seat unsettled, the now axial line of rotary shaft and the axial line conllinear of endoporus, the most fixing seat is vertically fixed in detection platform, as long as after now throttle linkage level being fixed, endoporus can be detected.Compare tradition to use dial gauge to carry out endoporus detection to need each self-retaining to be installed, for correction, install fixing more convenient.
Preferred version one: based on the preferred version of scheme, the middle part of described flexible fastening set is provided with inner core, this inner core overlaps interference fit with flexible fastening, the bottom of inner core is provided with a support plate, rotary shaft is followed successively by rotary head, swingle and lower rotary head from top to bottom, on this, rotary head is less than the gap of 0.005mm, lower rotary head and fixing seat junction again smaller than 0.005mm with the gap of inner core.The advantage of this programme is: upper rotary head and inner core are all rigid elements, and gap is less than 0.005mm, then go up rotary head during rotation, and the impact on inner core is less.The gap of lower rotary head and fixing seat is again smaller than 0.005mm, then rotary shaft produces the error causing result not over 0.005mm because rotating during rotating, and 2 of rotary shaft are spacing, and rotating the error produced can be less.
Preferred version two: based on scheme or the preferred version of preferred version one: scribble oil lamella on the inwall of described guide cylinder, when hard alloy steel ball moves in guide cylinder, hard alloy steel ball can be less by the resistance between guide cylinder, and the result of strain detector detection is more accurate.
Preferred version three: the preferably preferred version of two: be provided with elastic layer away from the end supporting seat on described guide cylinder, elastic layer can effectively avoid operator during detection, because misoperation causes guide cylinder end directly to contact with inner hole wall, inner hole wall occurs that situation about scratching occurs.
Preferred version four: the preferably preferred version of three: the bottom surface of described fixing seat is embedded with magnetic block, and the bottom surface of magnetic block flushes with the bottom surface of fixing seat.Fixing seat, when being installed to detection platform, can realize quickly pre-fixing by magnetic block, improves work efficiency.
