Summary of the invention
This problem to be solved is to provide a kind of mouthful machine of repairing of piston ring, allows gap-clearance of piston rings and repair mouthful more precisely, and size can regulate according to actual conditions at any time.
For completing foregoing invention object, the present invention realizes like this, a kind of piston ring port repairment machine, it comprises feed mechanism, delivery device, burring machine and dressing mechanism, described above-mentioned machine is linked in sequence, and it is characterized in that: described burring machine is by grinding head, and finishing mould overlaps and presses down delivery device and forms, described finishing mold integral is tubular, and barrel dliameter is identical with the external diameter of piston ring; On sidewall, have finishing mouthful, described grinding head is built in the finishing mouth of finishing mould; The described delivery device that presses down is built in finishing mould top, presses down the propelling movement platen diameter of delivery device between piston ring internal diameter and external diameter; On the sidewall of propelling movement platen, be provided with equally opening, aperture position is corresponding with the finishing mouth of finishing mould, and the sidewall opening that pushes platen can pass through for bistrique.
The present invention adopts mold pressing to send the mode of propelling to carry out secondary cut, principle is in fact, use mould big or small with standard piston ring external diameter and that openings of sizes is same, width and the gradient of the bistrique size of using are also identical with standard component A/F, gradient, allow such bistrique admittedly be inserted in the opening part that mould is corresponding, when piston ring or underproof piston ring slide from top to bottom along mould, underproof place, run into bistrique, just can be polished the pieces O.K. of standard.
Technique scheme is done to further refinement, and described finishing mould is divided into three parts from top to bottom, and upper part and lower part outwards all have tapering; The internal diameter size of mid portion is identical with the external diameter size of piston ring, and bistrique is made the annulus of tapering, and the width of intermediate portion is identical with standard component, and tapering is from inside to outside identical with your standard, and bistrique is fixed on the centre of whole finishing mould.Why this technical scheme became to have up and down certain taper piston ring Design of Dies is all bell-mouthed design up and down, because will guarantee his stationarity in the Piston Process that falls, we know, want the standard that allows piston mouth open, piston mouth must be aimed at mould openings so, right is more accurate, the standard of also just getting over being polished so, how guarantee they aim at, when material loading, to allow piston collar extension aim at mould mouth on the one hand, be exactly on the other hand to enter being placed into mould mouth, fall to wanting steadily, the tapering of so this loudspeaker opening just can allow piston ring steadily fall, guaranteed, the accuracy rate of aiming at.
Technique scheme is improved further, and other three faces at described finishing mould except finishing mouth are provided with and tighten the groove of taking blame for others, and described tightening taken blame for others and be installed in frame.The mould that this patent adopts can regulate, in process in the past, stationarity due to mould, often to do a set of, use a mold, very unrestrained useless, and in process, due to the extruding back and forth of upper platen, and some piston rings scripts is nonstandard, can cause to the use of normal time of mould shape the decline of accuracy rate, in order to prevent the generation of said circumstances, patent adopts the mode of three cylinders to top, by 3, positions, realization is tightened up mould, thereby rises for the correction producing in excessive use after error.Certainly these three points are arranged and are also said that these three should, in same level, form the round quartering with opening when studying carefully, only in this way guarantee is to the accuracy closing up, when share, take blame for others for three and can regulate by manual lead screw, also can complete by jacking cylinder.
Technique scheme is improved further, described pressure delivery device is by fixed mount, push motor, degree of subtracting machine, push screw mandrel and push platen and form, described propelling movement motor and degree of subtracting machine are fixed on fixed mount, and described propelling movement screw mandrel is connected with reductor, push platen and are installed on the top that pushes screw mandrel.It is that servomotor is controlled that described pushing mechanism adopts, and at the sidewall of repairing mould mould, is provided with position sensor, and described sensor is located at respectively the junction of two taperings.The technical program is improved for the propulsive mechanism in conventional art, mainly to be embodied in intelligentized control, what all adopted in the past, be that cylinder is controlled, it is in very large drawback so, controlled poor, this patent has been adopted the fit system of servomotor and screw mandrel, adopts in addition induction installation, in pushing away whole progradation, adopt different speed, thereby make the otch be up to finer and smoother.For example, in topmost portion, we require speed to want fast, because the level that speed can allow the piston of script freely falling body put soon, better aims at otch at once, and at interstitial segment, we will slowly push in requirement, to below we require again his fast he being pushed out.
Technique scheme is done further to optimize, at two sidewalls of the grinding head of finishing mould outside, is provided with two symmetrical cooling sparge pipes, bistrique have an abrasive dust feeder, in the bottom of feeder, be provided with and eject chute.In the source of chute, be provided with bits liquid/gas separator; Described bits liquid/gas separator is in the outer position that is adjacent to the magnetic axis of rolling of rotating shaft, to be provided with discreet knives by the magnetic axis of rolling; Below the magnetic axis of rolling, be provided with collection container, below discreet knives, be provided with scrap collecting bag.Two sidewall cooling sparge pipe front ends at mill grinding head are provided with scraping fluid baffle plate.Technique scheme is mainly to the supplementing of conventional art deficiency, as heat radiation, because some piston ring rigidity is very strong, after particularly we carried out speed adjusting above, polish finer and smoother, and for bistrique, its heat is also high, so will dispel the heat; On the other hand, in the prior art, these iron filings have all been thrown away, and for present, we will be collected by the mode of collecting, thereby cost-saving.
