Abstract
The utility model provides a tool bit of a tappet hole reamer, relating to a tool for finely finishing a hole. The tool bit of the tappet hole reamer is characterized by comprising a tool body, wherein a hard alloy guide is installed on the tool body; the hard alloy guide is installed at the middle of the tool body; one end of the tool body is provided with a connection end; the other end of the tool body is provided with the tool bit; a tool groove is carved on the tool bit; and blades which have a hard alloy structure are embedded in the tool groove. The tool bit of the tappet hole reamer is simple to connect and convenient to install, and can be used for long time.
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 cutter head.
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 traditional technology, the cutter head of reamer generally is divided into two parts; A part is used for squeezing, a part is used for hinge, but such cutter head is not easy installation, and the maintenance trouble; In work, error occurs, brought trouble to commercial production through regular meeting.
The utility model content:
The utility model technical problem to be solved is to overcome existing technological deficiency a kind of a kind of tappet hole reamer cutter head simple, easy for installation, that can use for a long time that connects is provided.
Technical scheme below the utility model technical problem to be solved adopts realizes:
A kind of tappet hole reamer cutter head is characterized in that: comprise cutter hub, the carbide alloy guiding is installed on the said cutter hub; Said carbide alloy guiding is installed in the cutter hub centre position, and said cutter hub one end is provided with and connects the termination, and the said cutter hub other end is provided with cutter head; Be carved with the cutter groove on the said cutter head, said blade is embedded in the cutter groove, and said blade is the blade of cemented carbide structure; When using, blade directly cuts with scissors, and does not need to squeeze earlier hinge, waste material again.
The beneficial effect of the utility model is: be carved with the cutter groove on the cutter head; Blade is embedded in the cutter groove, does not so need welding, and is can be because of welding high temperature etc. not former thereby make defectives such as blade cracks; Blade is a cemented carbide structure, and intensity is high, wear-resisting, use is lasting.That the utility model connects is simple, easy for installation, 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 cutter head comprises cutter hub 1; Carbide alloy guiding 2 is installed on the cutter hub 1, and carbide alloy guiding 2 is installed in cutter hub 1 centre position, and cutter hub 1 one ends are provided with and connect termination 3; Cutter hub 1 other end is provided with cutter head 4; Be carved with cutter groove 5 on the cutter head 4, blade 6 is embedded in 5 li of cutter grooves, and blade 6 is blades of cemented carbide structure.
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.
