Description
Technical field
The utility model relates to machinery knives technology and Machine Manufacturing Technology.
Background technology
Conventional rigid alloy bulk welding PCD blade, utilization rate is low, loss is fast, precision is low, circularity, linearity, roughness are poor, and burr appears in machining hole.
Summary of the invention
The purpose of this utility model improves PCD blade utilization ratio, Loss reducing, increases precision, circularity, linearity, roughness, improves PCD blade service life.
The technical scheme adopted for realizing the utility model object is such, for the tape guide bar reamer in processing automobile cylinder head guide pipe hole, comprises working portion, neck and retained part.
Before described working portion is positioned at neck.After described retained part is positioned at neck.
The front end of described working portion is welded with some PCD blades.The side of the first half of described working portion has some chip areas.
The latter half of described working portion is targeting part.Described targeting part is dodecahedron.In 12 faces of described targeting part, four faces be centrosymmetric are cambered surface, other eight faces are plane.Namely cambered surface described in four is gib block.
Described working portion and neck vertically center have Oil Guide through hole.
Described retained part vertically center has screwed hole.
Further, the front end of described working portion is welded with four PCD blades, i.e. PCD blade one, PCD blade two, PCD blade three and PCD blade four.These four PCD blades circumferentially install in the counterclockwise direction at 90 degree, interval in the anterior side of working portion, and make each blade main cutting edge be parallel to the axis of working portion.
Can repair after the utility model tool PCD blade abrasion, precision, cylindricity, linearity, roughness, height, PCD blade high life, the advantages such as production cost is low.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but should not be construed the above-mentioned subject area of the utility model and be only limitted to following embodiment.When not departing from the above-mentioned technological thought of the utility model, according to ordinary skill knowledge and customary means, making various replacement and change, all should be included in protection domain of the present utility model.
For the tape guide bar reamer in processing automobile cylinder head guide pipe hole, comprise working portion 1, neck 2 and retained part 3.
Described working portion 1 comprises leader and finishing portions.Before described working portion 1 is positioned at neck 2.After described retained part 3 is positioned at neck 2.
The front end of described working portion 1 is welded with some PCD blades.In embodiment, the front portion of described working portion 1 is welded with PCD blade 1, PCD blade 2 103, PCD blade 3 104 and PCD blade 4 105 for cutting.These four PCD blades are that circumferentially 90 degree, interval is installed in the counterclockwise direction in the anterior side of working portion 1, and make each blade main cutting edge be parallel to the axis of working portion 1.
The side of the first half of described working portion 1 has some chip areas, for discharging chip.
The latter half of described working portion 1 is targeting part.Described targeting part is dodecahedron.In 12 faces of described targeting part, four faces be centrosymmetric are cambered surface, other eight faces are plane.Namely cambered surface described in four is gib block.Increase director strip and can improve linearity and cutter life.
See accompanying drawing 3, the cross section of targeting part is the centrosymmetric image surrounded by 12 limits, and its central point is o.In these 12 limits, four edges is arc section, eight limits are straightways.Article four, the center of circle of arc section is o point, and the center of circle of four arc sections is on the axis of targeting part.The two ends of each arc section are all connected with straightway.One end of each straightway is connected with arc section, the other end is connected with other straight line section.In embodiment, the radius of each arc section is R, and the distance of the two ends of each straightway and o point is k.Due to R > k, the arc surface with regard to making arc section corresponding protrudes from the plane on targeting part, forms the axial projection bar of targeting part outer surface.What deserves to be explained is, the targeting part of the present embodiment can adopt various ways to process, in order to its shape is described better, the present embodiment is specifically described a kind of processing mode: described targeting part is cylinder, this cylindrical outer surface is cut out eight planes.Four arc surfaces do not processed (namely original cylindrical outer surface) are retained between these eight planes.
Described working portion 1 and neck 2 vertically center have Oil Guide through hole 4.Cold oil flow to cutting tip by above-mentioned oilhole, reaches cooling object.
Described retained part 3 vertically center has screwed hole 5.Described screwed hole 5 is in order to understand handle of a knife.The shank of described retained part and cutter is a nonstandard taper shank as shown in Figure 4.Make whole cutter positioning standard, good rigidly, datum level, screw thread drawknot mode, convenient and swift.
