Description
Technical field
The present invention relates to a kind of processing method that head and inlet and exhaust valve seat ring occur, especially a kind of method head occurring and adopts the same model generation head processing inlet and exhaust valve seat ring conical surface, the fine finishining of different size, the different angles inlet and exhaust valve seat ring conical surface can be realized, belong to engine production technical field.
Background technology
In engine cylinder cover inlet and exhaust valve seat ring cone face process, according to product structure feature and hole layout, conventional scheme adopts taper to rotate generation head supporting machinery and drives the processing carrying out the seat ring conical surface, there is head and only have axial SERVO CONTROL in this kind, after silico analysis calculates, there is head indoor design a set of fixing, mechanical expansion motion and processed by the seat ring conical surface in the angle of its seat ring conical surface.Under normal circumstances, inlet and outlet seat ring there is difference in size and frustoconical bevel angle is different, and thus such generation head need for the separate design of intake and exhaust seat ring of different size, different angles.
There is head and there is following defect in above-mentioned routine: owing to there is scalp acupuncture to intake and exhaust seat ring size and frustoconical bevel angle different designs, and the processing of the conical surface relies on the matching of a set of mechanical expansion mechanism to form, therefore once manufacture and design, intake and exhaust generation head non-interchangeability, air inlet generation head can only processing gas inlet seat ring, and head occurs in exhaust can only process exhaust valve seat insert.For the upgraded product that frustoconical bevel angle slightly adjusts, there is head and cannot use in this kind, all need redesign manufacture, and thus it is flexible poor, cannot adapt to the upgrading of product.Because intake and exhaust position routine all adopts irregular layout, but not rhombus layout, 1 station is arranged as only purchased 1 special plane, two main shafts not only need to possess to vertically move function, and 2 between centers also need to possess the processing mutually can moving to adapt to the irregular intake and exhaust seat ring conical surface, device structure is complicated, causes purchase cost high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of method head occurring and adopts the same model generation head processing inlet and exhaust valve seat ring conical surface is provided, the generation head of same model structure can realize the processing of different size, the different angles intake and exhaust seat ring conical surface, can increase substantially and head flexibility occurs, adapt to the updating and upgrading of a product.
According to technical scheme provided by the invention, a kind of generation head, comprise machine tool chief axis, machine tool chief axis end is installed to rotate and head is occurred, feature is: described rotation occurs to arrange axle sleeve in the middle of head, arrange in axle sleeve and head inner drive shafts occurs, head inner drive shafts occurs and is connected with machine tool chief axis Inner link axle; Arrange chute in the described bilateral symmetry that head inner chamber occurs that rotates, chute is arranged along rotating the radial skew that head occurs, and arranging in chute can along the sliding wedge of slide; Install adapter sleeve in an end of described generation head inner drive shafts, adapter sleeve is connected with sliding wedge, arranges shoulder hole in the other end inside that head inner drive shafts occurs; Roughing tool tool rest and finishing tool tool rest are installed respectively in the outer end of two sliding wedges, roughing tool tool rest and finishing tool tool rest install roughing tool and finishing tool respectively.
In the inside of described generation head inner drive shafts, reamer is installed.
The method of the described employing same model generation head processing inlet and exhaust valve seat ring conical surface, is characterized in that, adopt following processing step:
(1) machine tool chief axis starts rotation, and driven rotary generation head, generation head inner drive shafts rotate;
(2) while rotating generation head and the rotation of generation head inner drive shafts, the Inner link axle of machine tool chief axis pulls and head inner drive shafts occurs, thus sliding wedge occurs to slide outside head along chute to rotating and drives roughing tool and finishing tool to the movement outside of inlet and exhaust valve seat ring;
(3) lathe tool moves to the origin position of the inlet and exhaust valve seat ring conical surface, and the initial point of the inlet and exhaust valve seat ring conical surface is the starting point outside the inlet and exhaust valve seat ring conical surface;
(4) according to the flex point on required inlet and exhaust valve seat ring conical surface surface, the conical surface is divided into multistage surface, the feed path of lathe tool is the destination county be positioned at along each section surface of the conical surface successively milling to the conical surface by initial point inside inlet and exhaust valve seat ring; The feed path of feed and the mating shapes of the inlet and exhaust valve seat ring conical surface; In process, rotate while head occurring and the rotation of head inner drive shafts occurring, the Inner link axle of machine tool chief axis promotes head inner drive shafts occurs, machine tool chief axis moves radially along inlet and exhaust valve seat ring, makes roughing tool and finishing tool complete the processing to the inlet and exhaust valve seat ring conical surface along feed path;
(5), after processing knot speed, withdrawing, makes lathe tool get back to the initial point of the inlet and exhaust valve seat ring conical surface.
The present invention has following beneficial effect: (1) same model structure generation head can realize the processing of different size, the different angles inlet and exhaust valve seat ring conical surface; (2) the present invention can realize the processing of larger conical surface angle requirement in scope of design, significantly can improve the flexibility that a nonstandard class cutter occurs, and adapts to the updating and upgrading of a product; (3) the present invention can reduce the complexity of equipment, thus reduces equipment purchase cost.
