Description
Technical field:
The utility model relates to a kind of finishing tool of hole, is specifically related to a kind of tappet hole reamer guider.
Background technology:
On engine; Tappet is the driven member of cam, and its effect is that motion and active force from cam are passed to push rod or valve, the side force of also bearing cam simultaneously and being applied; And it is passed to a body or cylinder cover; In traditional processes, processing needs through reaming lathe, bore hole lathe and cuts with scissors empty lathe, just can machine; And reamer has one or more cutters tooth, in order to excise the rotary cutter of hole surface sheet metal, have the rotation finishing tool of straight sword or helical edges, be used for reaming or repair the hole; Reamer structure major part is made up of working portion and shank, and working portion mainly plays cutting and calibration function, and calibration place diameter has back draught; Shank then is used for by the anchor clamps clamping branch of staight shank and taper shank being arranged, and reamer is divided into hand reamer and chucking reamer by occupation mode; Be divided into cylindrical reamer and taper reamer, the chip pocket direction of reamer, straight trough and helicla flute by the fraising shape; Material commonly used is high-speed steel, carbide alloy empiecement; And in the middle of traditional manufacture craft, guider generally all is welded on the reamer, is easy to like this cause cracking etc. defective because of welding; Greatly reduce operating efficiency, reduced the working time, also want frequent maintenance, replacing.
The utility model content:
The utility model technical problem to be solved be to overcome existing technological deficiency provide a kind of rational in infrastructure, relevance grade is high, a kind of tappet hole reamer guider that can use for a long time.
Technical scheme below the utility model technical problem to be solved adopts realizes:
A kind of tappet hole reamer guider is characterized in that: comprise cutter hub, said cutter hub one end is provided with and connects the termination; The said cutter hub other end is provided with cutter head, is carved with the cutter groove on the said cutter head, and said blade is embedded in the cutter groove; Said blade is the blade of cemented carbide structure, and said cutter hub is provided with gathering sill, and said gathering sill has six; Said gathering sill is engraved on the cutter hub, with cutter hub be an integral body.
The beneficial effect of the utility model is: gathering sill is engraved on the cutter hub, no longer need use guider as through being welded to connect carbide alloy, and gathering sill and cutter hub are an integral body, has saved material, has also increased the intensity of structure, is not easy to damage.The utility model is rational in infrastructure, relevance grade is high, can use for a long time.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the partial section of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1 and shown in Figure 2, a kind of tappet hole reamer guider comprises cutter hub 1; Cutter hub 1 one ends are provided with and connect termination 3, and cutter hub 1 other end is provided with cutter head 4, and cutter hub 1 is provided with gathering sill 2; Gathering sill 2 has six, and gathering sill 2 is engraved on the cutter hub 1, with cutter hub 1 be an integral body.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
