Detailed description of the invention
Now the utility model is described in further detail by reference to the accompanying drawings
A kind of connecting rod diplopore right boring positioner, comprise the respective locating shaft of stationary links 1 size diplopore, its structure is: positioner is symmetrical structure; Described locating shaft is the cylinder of end belt inclination conical surface groove, is called mandrel 11,12; Around 360 degree on the inclination conical surface, be dispersed with the pressed slider 19 that can slide along the inclination conical surface equably; Pressed slider vertical spindle, be installed on movingly respectively in the aperture of connecting rod diplopore alignment pin 5,6 tube wall separately, pressed slider head pushes up tie rod holes inwall slidably, realizes connecting rod 1 size diplopore location; Mandrel afterbody and hydraulic cylinder piston rod 7,8 connect, hydraulic cylinder piston rod tail and limited block 13, and 14 is fastening; The baseplane of limited block and the parallel separation of being separated by of proximity transducer 17,18 transverse plane; Proximity transducer is fastened on sensor stand 15, on 16, and sensor stand and hydraulic cylinder seat 3,4 is fastening; Hydraulic cylinder seat and hydraulic cylinder piston rod seam crossing have seal cover 9, and 10 hydraulic cylinder seat front ends are connected with tie rod holes alignment pin; Two hydraulic cylinder seat afterbodys are fastened on the total pedestal 2 of two installing holes respectively, form connecting rod diplopore right boring positioner.
Described pressed slider, its connecting rod macropore pressed slider is three pieces, according to equilateral triangle distribution, on one block pressed slider 19 place interlinking lever end axis; Its connecting rod aperture positioning sliding block is two piece 22,23, on the both ends of point other places vertical links axis.
Described parallel separation of being separated by, its fractional dose L is that mandrel promotion pressed slider withstands tie rod holes inwall, and the amount of movement of its limited block, is measured by proximity transducer.
Embodiment
The concrete steps of utility model works process are:
Step 1: in the big end hole alignment pin 5 that the large and small head bore of connecting rod 1 is inserted in this device respectively and little head bore alignment pin 6, this step is completed automatically by manipulator usually;
Step 2: hydraulic cylinder performs an action, hydraulic cylinder piston rod 7,8 is with moving mandrel 11,12 to move to the direction of connecting rod 1 respectively;
Step 3: under the promotion of mandrel 11,12, pressed slider 19,20,21,22,23 outwards slides in the aperture of large and small head bore alignment pin, until compress the inner surface of tie rod holes, hydraulic cylinder stops action.Achieve the location that centers to connecting rod 1 like this.
Step 4: while hydraulic cylinder performs an action, hydraulic cylinder piston rod 7,8 drives limited block 13,14 to move to connecting rod 1 direction respectively;
Step 5: during hydraulic cylinder stopping action, proximity transducer 17,18 detects limited block 13,14 and the distance between it.If this distance is within setting range, illustrates that connecting rod centers and put in place; If this distance exceeds setting range, then illustrate that connecting rod centers and do not put in place, now lathe can provide alarm signal.
Such as, when connecting rod small end hole is not inserted in little head bore alignment pin, because pressed slider is not by the constraint of microcephaly's internal surface of hole, drive piston rod continues to move to the direction of connecting rod by hydraulic cylinder, causes the distance of limited block 14 movement to exceed correct scope.The distance that proximity transducer 14 detects also will exceed setting range.Lathe stops follow-up action by according to this signal, sends warning, prevents the generation of collapsing cutter or main shaft damage fault.
