Abstract
The utility model relates to a diamond reamer for an air valve base, comprising a reamer rod, stirring rod and reamer bodies with various working angle. The conical working surface of each reamer body is provided with a working layer which is formed by composite electroplating and electroforming processes to combine diamond grinding particles with electroplating metal. The diamond reamer for an air valve base has high hardness, strong wear resistance, high reaming precision, good reaming and grinding uniformity for one batch. The utility model is a novel cutting tool for processing the air valve base of an engine.
Description
The utility model belongs to interior aperture knife tool, is specifically related to a kind of diamond reamer that is used to process engine valve seat.
Along with developing rapidly of auto industry, the demand of valve seat reamper also constantly increases.Although present employed carbide tipped valve seat reamer is improved from quality and structure, along with the improvement of valve seating organism material, the raising of hardness and anti-wear performance makes the durability of alloy reamer reduce relatively.Cause product processed quality instability, the cutter consumption is big, and engine manufacturing and maintenance cost are corresponding to be increased.
The purpose of this utility model provides the diamond valve seat reamper that a kind of hardness height, wearability are strong, hinge is ground high conformity.
Technical solution of the present utility model is: this diamond valve seat reamper is made up of reamer bar, the reamer body that stirs bar and various operating angles.On the taper work face of reamer body, have by composite plating and electroforming process diamond abrasive grain is combined the working lining that forms with plated metal.
The utility model is to utilize metal ion under the direct current effect, and the principle that deposits on cathode mechanically is wrapped on the matrix abrasive particle (bortz) by metal level, forms the working lining of reamer.After tested diamond abrasive grain plated metal in conjunction with base in, it is good to control intensity, abrasive particle φ 80～100 μ m control intensity and are not less than 15kg.Because the combination of diamond tool body running face is to electroplate in conjunction with base, no HTHP, thus the no any damage of diamond itself, so there are enough hinges to grind intensity.
The utility model diamond valve seat reamper is compared with carbide tipped valve seat reamer, and its operating accuracy, roughness and durability all are better than carbide-tipped reamer, provides guarantee to grade on the product quality.
1, employing plating electroforming process without any damage, has kept the characteristic of diamond abrasive itself to diamond abrasive grain, fraising precision height, and tolerance is little.
2, one of characteristics of diamond valve seat reamper are that the processing work roughness is little, this be other cutter can not compare, the roughness of carbide tipped valve seat reamer is Ra0.32～0.63 μ m, and the roughness of diamond valve seat reamper is Ra0.04～0.08 μ m.
3, the diamond valve seat reamper is 35～40:1 with the durability ratio of carbide tipped valve seat reamer, and the price ratio is 2～2.5:1.When the carbide tipped valve seat reamer hinge amount of grinding reaches 300～350 times/hole, the tipping phenomenon occurs, and the diamond valve seat reamper hinge amount of grinding still can normally be used when reaching 12000～16000 times/hole.As seen the comprehensive effect height of diamond valve seat reamper, this plays a positive role to reducing product cost, also can reduce test stage simultaneously, save man-hour.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is that reamer body running face diamond abrasive grain layer is arranged schematic diagram.
Fig. 3 is Fig. 2 A-A cutaway view.
The diamond valve seat reamper can be made motor-driven reamer and manual reamer.Figure 1 shows that manual reamer, it is by reamer bar 1, reamer body 2 and stir bar 3 and form.Adopt " composite plating+electroforming process ", its coating hardness is 38 °～40 ° of Rockwells.
This diamond abrasive grain layer 4 can be distributed in reamer body running face, also can be spaced apart in reamer body running face, as Fig. 2, shown in Figure 3 according to certain angle.
Claims (4)
1, a kind of diamond valve seat reamper, be made up of reamer bar, the reamer body that stirs bar and various operating angles, feature of the present utility model is: have on the taper work face of reamer body by composite plating and electroforming process diamond abrasive grain is combined the working lining that forms with plated metal.
2, diamond valve seat reamper according to claim 1 is characterized in that above-mentioned diamond abrasive grain layer is spaced apart in reamer body running face according to certain angle.
3, diamond valve seat reamper according to claim 1 is characterized in that above-mentioned diamond abrasive grain layer is distributed in reamer body running face.
4, diamond valve seating hinge power according to claim 1 is characterized in that this reamer is motor-driven or manual reamer.
