Description
Technical field
The present invention relates to a kind of quality check tool of engine link, be mainly used in engine connecting rod big end oilhole and
The inspection of the foreign matters such as iron filings, burr in slip groove, it may also be used for the filth test of other similar deep hole undercuts.
Background technology
Connecting rod is one of primary drive part of engine（See Fig. 1,2）, it links up piston and bent axle, makes the past of piston
Linear motion is changed into the gyration output power of bent axle, in motion process, between crank pin end pore hole wall and bent axle
Lubricate most important, major part oilhole 15（See Fig. 3）The effect of oil transportation and oil storage is act as in greasing, in connecting bar and crankshaft fortune
When dynamic, under the effect of the pressure, the oil of the inside forms spray regime to oilhole, reaches the effect of lubrication.Therefore, big end oilhole
Aperture size can not be excessive, and must assure that oil circuit is unimpeded in the course of the work.But because oilhole is stepped hole, size
It is little（Usual aperture 1-1.1mm of φ, macropore 2-3mm of φ, long more than 16mm）, so machining difficulty is big, in metal cutting
Cheng Zhong, some little iron filings can stay in unavoidably oilhole the inside, and naked eyes are difficult to observe, due to depositing for oilhole iron filings
So that oilhole is blocked, and the thing followed is that the lubricant effect of whole connecting bar and crankshaft system is bad, causes crankshaft connecting rod system to be received
To serious abrasion or burn, make the lost of life of engine or scrap.Slip groove（Undercut）It is the one of crank pin end pore inwall
Two sections of upper and lower deep-slotted chip breakers 16 of side（See Fig. 2,4）, general depth 3mm, wide 3mm are mainly used in the bearing shell fixation installed in device to hole
Effect, slip groove has iron filings that bearing shell can be affected to fix, and iron filings meeting nature is shifted between crank pin end pore inwall and bent axle, together
Sample causes serious abrasion or burn.
These all can suffer greater loss to above phenomenon to the interests of producer and user, therefore in major part oilhole and slip groove
Processing after, be not allow for iron filings or other foreign matters stay in the inside, because big end oilhole belongs to micro deep-hole, slip groove belongs to
Whether undercut, have the foreign matters such as iron filings to be difficult to distinguish in groove, it is necessary to be checked in device to hole, if just being carried out with instruments such as draw points
Cleaning.This operation workload is big, and difficulty is also big, because oilhole aperture is in macropore inwall, does not possess good test condition,
The method of inspection is manually, by being irradiated with flashlight, directly to visually observe, and the eyes of people and the light of flashlight are to regarding
, and the angle of manual observation oilhole affected by connecting rod shape, it is impossible to the face of oilhole inwall and slip groove is seen completely
Wall, often results in inspection erroneous judgement, and manually in working long hours, eyes are easily tired.This method of inspection can only be inadequate
The task of completing, but operating difficulties are dealt with, more personnel's input is needed, and the quality fluctuation checked is larger, some are unqualified
Product be also mixed into wherein, production efficiency is low, difficult quality guarantee.Therefore, it is necessary to seek a kind of new approach, this is solved
Technical barrier.
The content of the invention
The main technical problem to be solved in the present invention and purpose are：Deposited according to existing big end oilhole and slip groove inspection
Defect, the means combined using machinery positioning and electronic information technology design a kind of checking system, to the big of connecting rod
Hair oil hole, slip groove are tested, and fundamentally overcome operating difficulties, quality inspection to be difficult to the phenomenon for ensureing, are reached effectively
Improve production efficiency, it is ensured that quality inspection, meets the big end oilhole of many specifications of high-volume and the inspection demand of slip groove.
The main technical schemes of the present invention：The present invention includes base, V-arrangement locating piece, bolt, the first bearing, light source, display
Device, computer, camera, the second bearing, swivel head, locating piece, three abutments, screw, concrete structure：By V-arrangement locating piece and calmly
Position block is arranged on base according to the relative dimensions of tested connecting rod by bolt, and makes the working face of V-arrangement locating piece, locating piece
In same plane；Camera is fixed by screws in the swivel head of the second bearing, is arranged on connecting rod by bolt together big
Head bore side, camera is rotatable；Camera is fixed by screws in three abutments, is arranged on connecting rod by bolt together big
Head bore centre, the optical axis of camera and the dead in line of major part oilhole；Light source is screwed in the hole of the first bearing
It is interior, it is arranged on the upper right side of base and the position of major part oilhole center line extended line by screw together；By two cameras
Output end is connected to computer by interface, and computer is connected with display.
The present invention is proved by practical probation：Development purpose is fully achieved, connecting rod need only be positioned, Jing cameras are completely taken the photograph
As amplifying, present over the display, the feelings that directly whether there will be the foreign matters such as iron filings, burr in the major part oilhole and slip groove of connecting rod
Condition is clearly errorless to be shown, and for viewing, quality inspection is protected completely；Simultaneously by the locating piece position of adjustment connecting rod
Put, be applicable to the connecting rod inspection of plurality of specifications size；The present invention is simple to operate, and labour intensity is low, more than five times of raising efficiency,
The production needs of many specifications of connecting rod high-volume are adapted to completely.
