Abstract
The utility model discloses a fire-new universal shaped valve reamer, which is composed of a guide rod, a cutter head, a special-shaped spring cushion, a 45 DEG blade, a 75 DEG and 15 DEG blade, a special-shaped cushion ring, nuts, positioning screws, a regulating rod and a boosting rod. The utility model is characterized in that six separate blades which are divided into two kinds are inserted on the cutter head, and the extension length of the blades can be adjusted by the regulating rod; three conical surfaces with different angles of valve seats with different sizes can be processed at one time, the cutter scratch can not remain, and the smoothness is high. The utility model can be combined with the valve seat slightly to achieve the sealed requirement.
Description
The utility model relates to the metal processing patent cutter in the instrument class, refers to a kind of general valve seating typing reamer especially.It is widely used in the manufacturing and the repairing of engine valve seat.
The valve seat reamper of market circulation now roughly has two kinds: 1, tool steel valve seat reamper; 2, carbide tipped valve seat reamer.Both structures are basic identical, all are by guide post, and cutterhead and boosting-rod are formed.Because valve seating has the conical surface of three different angles, thus the cutterhead of three groups of different angles of needs, according to different processing capacities, every group of cutterhead also need be equipped with size different several cutterheads.Every articulation once all need be changed cutterhead one time, and stops cutter and will stay tool marks.
The purpose of this utility model is that a kind of general valve seating typing reamer will be provided.It has only a cutterhead, and two kinds of different blades are contained in six insert grooves at interval, the conical surface of three different angles of articulation simultaneously.
The purpose of this utility model is to realize like this.General valve seating typing reamer is by guide post, cutterhead, heterotypic spring pad, 45 ° of blades, 75 °, 15 ° double-edged blades, profile washer, nut, dog screw, adjusting rod and boosting-rods are formed, guide post is inserted solid on cutterhead by the end tapering, nut is six special square nuts, dog screw is six side's screws that head has polished rod, and boosting-rod interts in the cross-drilled hole of adjusting rod end.It is characterized in that: there is individual internal taper hole the upper end of cutterhead, straight-through hole down, individual folk prescription is arranged on the cylindrical, two relevant blade positioning cylinders are arranged in the middle of it, in unthreaded hole is arranged, its lower end has the blade locating slot of six symmetries, positioning cylinder in the middle of straight-through, cylindrical is a screw thread, and endoporus has the internal thread of suitable length, and the locking screw of two symmetries is arranged on the suitable position; Heterotypic spring pad porose plum blossom disk spring pad in the middle of being, profile washer have the plain cushion of six symmetrical pawls in being; 45 ° of blades are carbide alloy cuboids, and a side has 45 ° of blades, and respective side has 45 ° to regulate the inclined-plane; 75 °, 15 ° double-edged blades also are the carbide alloy cuboids, and a side has 75 °, 15 ° double cutting edges, and respective side has 45 ° to regulate the inclined-plane, and 75 ° opposite with 15 ° of blade directions, and during assembling, 15 ° of blades are identical with the direction of 45 ° of blades; The head of adjusting rod is 90 ° a cone, and the centre is a polished rod, has six symmetrical elongated slots of suitable length to connect one section double-screw bolt on it, and afterbody is the polished rod that has a cross-drilled hole.
The utility model has the advantages that and have only a cutterhead, need not change cutterhead, regulate the valve seating that the blade extension gets final product the articulation different size, because 45 ° identical with 15 ° of blade directions, 75 ° of blade directions are opposite, can not stay tool marks in the articulation, as long as anti-hinge gently not only can be repaired 75 ° of conical surfaces, and can grind 45 °, the 15 ° conical surfaces, improve its fineness.Thereby can obviously reduce amount of grinding with valve.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
The front view of Fig. 1 the utility model first embodiment;
The vertical view of Fig. 2 the utility model first embodiment;
The A-A cutaway view of Fig. 3 the utility model first embodiment;
45 ° of blade figure of Fig. 4 the utility model;
75 °, 15 ° blade figure of Fig. 5 the utility model;
Fig. 6 the utility model profile washer figure;
Fig. 7 the utility model heterotypic spring pad figure.
Referring to Fig. 1-7, the utility model first embodiment-general valve seating typing reamer is made up of guide post 1, cutterhead 2,3,45 ° of blades of heterotypic spring pad 4,75 °, 15 ° double-edged blades 5, profile washer 6, nut 7, dog screw 8, adjusting rod 9 and boosting-rods 10.Guide post 1 is inserted solid on cutterhead by the end tapering, nut 7 is six special square nuts, dog screw 8 is six side's screws that head has polished rod, boosting-rod 10 interts in the cross-drilled hole of adjusting rod 9 ends, it is characterized in that: there are individual internal taper hole, straight-through hole down in the upper end of cutterhead 2, individual folk prescription is arranged on the cylindrical, and there are two relevant blade positioning cylinders at its middle part, in unthreaded hole is arranged.Its lower end has the blade locating slot of six symmetries, the positioning cylinder at straight-through middle part, and cylindrical is a screw thread, endoporus has the internal thread of suitable length, and the locking screw of two symmetries is arranged in place.Heterotypic spring pad 3 is plain cushions that six symmetrical pawls 61 are arranged in middle porose plum blossom disk spring pad, profile washer 6 is.45 ° of blades 4 are carbide alloy cuboids, and a side has 45 ° of blades 41, and respective side has 45 ° to regulate the inclined-plane, and 75 °, 15 ° double cutting edge 51,52 respective side have 45 ° to regulate the inclined-plane.75 ° opposite with 15 ° of blade 51,52 directions, and 15 ° of blades 52 are identical with the direction of 45 ° of blades 41 during assembling.The head of adjusting rod is 90 ° a cone, and the centre is a polished rod, and the symmetrical elongated slot of six suitable lengths is arranged on it, connects one section double-screw bolt, and afterbody is the polished rod that has a cross-drilled hole.
During use, according to the size of valve seating, after the extension with adjusting rod 9 adjustment blades 4,5, with spanner fastening nut 7 that blade 4,5 is fixing, the screwed in place screw 8 then, put on boosting-rod 10, insert firmly guide post 1, can carry out articulation.In the articulation, when the ream of 45 ° and 15 ° blades 41,52 of 75 ° of blades 51 restriction, reverse 75 ° of conical surfaces of articulation lightly.Simultaneously can grind 45 °, the 15 ° conical surfaces, improve its fineness, can not stay tool marks again.Therefore, under the situation of not tool changing dish, an articulation survives.
The general valve seating typing reamer of the utility model second embodiment, identical with the structure of first embodiment, it is characterized in that: 45 ° of blades are steel cuboids, 45 ° of blades are to be ground by the hard alloy blocks in the brazing, 75 °, 15 ° of double-edged blades 5 also are the cuboids of steel, 75 °, 15 ° blades also are the steel cuboids, and 75 °, 15 ° blades are that the hard alloy blocks in the brazing grinds.
In a word, not tool changing of general valve seating typing reamer dish is adjusted the extension of blade, and the conical surface that can three different angles of an articulation does not stay tool marks, and is highly polished, as long as grind a little with valve, just can reach the requirement of sealing.
