Abstract
The invention relates to a method for sealing a conical surface by a reaming and grinding cylinder cover valve, comprising the following steps: (1) installing a blank cylinder cover on a machining center; firstly, machining a positioning plane; machining a dowel hole on the positioning plane by the technical steps of drilling, boring and reaming; setting a positioning reference by using the dowel hole on the positioning plane; machining the inner bore of a valve conduit and a race conical surface by a guiding cutter; machining and shaping the inner bore of the valve conduit and a race hole by a compound tool; quenching the race conical surface by laser, wherein the hardness is 50HRC; clamping the part of the race conical surface on the tool; regulating a dedicated grinding head, wherein the bounce of a guiding part and a clamping part is not more than 0.015mm; moving the center of the cutter bar to the center of the valve conduit; regulating the revolving speed, the feeding speed and the feeding mode of a grinding wheel; machining the race conical surface; after machining, moving to the canters of other conduits; repeating the above working procedures; and finishing machining the part. According to the method, the problem that the race conical surface of which the hardness is more than 50HRC on the cylinder cover is difficult to machine is solved, the machining cost is low, the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of machining process, be specifically related to a kind of method of ream mill head valve sealing cone.
Background technology
Engine cylinder cap is one of vital part on the engine, intake and exhaust on the engine are mounted on valve opening and closing the carrying out work on the cylinder cap, valve is high-speed motion in valve guide hole, when needs are closed intake and exhaust, intake and exhaust valve-face and head valve sealing cone are fitted, and reach sealing effectiveness.Therefore, the requirement of beating of the relative valve guide hole of sealing cone on the cylinder cap is very high.The inlet and exhaust valve sealing cone on it and the processing of valve guide hole are the difficult points of cylinder cap processing.
General engine cylinder cap is all adorned valve retainer, and the material of valve retainer is structural alloy steel or alloy cast iron, quenches before the cylinder cap of packing into, and hardness is generally less than 45HRC.Therefore the processing technology of domestic and international this part is a compound tool, the fine finishining that is valve guide hole and valve retainer is shaped by the cutter time processing, because the hardness of the quenching conical surface is inhomogeneous, mainly be that the foundry goods bulk material is difficult to evenly, the local hard spot that produces, cause in process, occurring cutter spring sword problem, cause processing to carry out, influence processing progress.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of ream mill head valve sealing cone, this method is easy to operate, solve on the cylinder head hardness greater than the difficult processing problems of the 50HRC seat ring conical surface, overcome the problem that occurs cutter spring sword in the process, improved operating efficiency.
Technical scheme of the present invention: a kind of method of ream mill head valve sealing cone, it may further comprise the steps:
(1) the blank cylinder cap is contained on the machining center, process its plane of orientation earlier, by the dowel hole on the processing step processing plane of orientation of brill, boring, hinge, the blank cylinder cap is located the hole on plane and screwed hole in the processing by the dowel hole on the plane of orientation, the hole of two sides, groove, bore oblique oil hole, the mill plane of orientation reaches goes up plane, boring valve guide hole on cylinder cap, the dress valve guide bushing is set the position benchmark with the dowel hole of plane of orientation;
(2) use the guide knife processing valve guide bushing endoporus and the seat ring conical surface earlier, adopt compound tool once valve guide bushing endoporus and seat ring hole to be shaped;
(3) counter race conical surface laser quenching, hardness reaches 50HRC;
(4) seat ring conical surface part is installed with frock on, use Position with One Plane and Two Holes with the location of frock, the side face of frock is equipped with the diamond cutter of repairing emery wheel, regulates grinding head dedicatedly, makes leader and the beating and be not more than 0.015mm partly of being installed;
(5) the knife bar center is moved to a valve guide bushing center, regulate rotating speed, feed speed, the feeding mode of emery wheel, the counter race conical surface is processed; When the emery wheel blunt, by diamond cutter to be contained on the main shaft and emery wheel is repaired, the relative motion between them by the establishment patching plug program finish;
(6) step (5) processes and moves to other catheter center, repeats above-mentioned operation, and part can machine;
(7) use vernier depth gauge to detect the conical surface degree of depth, use appliance special for detecting to tint and detect the applying degree of the conical surface.
The present invention compared with prior art has following beneficial effect: the invention solves on the cylinder head hardness greater than the difficult processing problems of the 50HRC seat ring conical surface, beating≤0.03mm of the relative valve guide hole of the seat ring conical surface, roughness≤0.8 μ m, thereby saved valve grinding technology after the processing, because the common apparatus processing that this technology work in-process is so in the heart, therefore cost is low, has improved operating efficiency.
The specific embodiment
A kind of method of ream mill head valve sealing cone, it may further comprise the steps:
(1) the blank cylinder cap is contained on the machining center, process its plane of orientation earlier, by the dowel hole on the processing step processing plane of orientation of brill, boring, hinge, the blank cylinder cap is located the hole on plane and screwed hole in the processing by the dowel hole on the plane of orientation, the hole of two sides, groove, bore oblique oil hole, the mill plane of orientation reaches goes up plane, boring valve guide hole on cylinder cap, the dress valve guide bushing is set the position benchmark with the dowel hole of plane of orientation;
(2) use the guide knife processing valve guide bushing endoporus and the seat ring conical surface earlier, adopt compound tool once valve guide bushing endoporus and seat ring hole to be shaped;
(3) counter race conical surface laser quenching, hardness reaches 50HRC;
(4) seat ring conical surface part is installed with frock on, use Position with One Plane and Two Holes with the location of frock, the side face of frock is equipped with the diamond cutter of repairing emery wheel, regulates grinding head dedicatedly, makes leader and the beating and be not more than 0.015mm partly of being installed;
