Abstract

The utility model discloses a small-taper-shank reamer which comprises a reamer bit portion and a reamer body integrally connected with a reamer handle portion. Reamer grooves are arranged on the reamer bit portion, blades are arranged in the reamer grooves and arranged uniformly and at intervals around the central axis of the reamer body, and the blades are arranged slantwise and clockwise relative to central axis of the reamer body. By means of the small-taper-shank reamer, the surface smoothness and accuracy of machining holes can be improved.

Description

Little taper-shank reamer
Technical field
The utility model relates to a kind of little taper-shank reamer.
Background technology
Reamer is usually used in the hole after drilling (or reaming) processing on the ream workpiece, mainly is in order to improve the machining accuracy in hole, to reduce its surperficial roughness, is fine finishining and the semi-finished cutter for the hole, and allowance is generally very little.Existing little taper-shank reamer machining accuracy is lower, and finished surface easily has scratch, and the surface smoothness of workpiece and precision are all not high enough, and cutting speed is low.
The utility model content
The purpose of this utility model provides a kind of little taper-shank reamer that improves surface smoothness and the precision of machining hole.
For achieving the above object, the utility model adopts following technical scheme: a kind of little taper-shank reamer, comprise the cutter hub that is connected and composed by cutter head part and shank portion integral type, cutter head partly is provided with the cutter groove, in the cutter groove blade is set, insert ring arranges around the uniform interval of cutter hub central axis, and the central axis of the relative cutter hub of each blade is obliquely installed clockwise.
The relative cutter hub central axis of blade tilt 17 ° 30 '-18 ° 30 ' between.
Cutter head part and shank portion are that front and back arrange, and shank portion be round table-like to after-contraction, and cutter head rear end partly is provided with the border and extends handle of a knife round platform front end rear end face outward.
Establish the central water flooding hole in the described cutter head part, shank portion is provided with the bolt hole that is communicated with the central water flooding hole.
Little taper-shank reamer described in the utility model after blade is obliquely installed, can make cutting swarf discharge forward, is unlikely to abrade machined surface, can improve the crudy in hole.Improve the cylindricity in surface smoothness, precision and the hole in hole, the aperture variation is few, and has reduced labour intensity.Cutter has the dual location of the conical surface and the cutter head part rear end face of round platform, locatees more accurately, has improved machining accuracy too, and then has improved working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
By a kind of little taper-shank reamer illustrated in figures 1 and 2, comprise the cutter hub that is connected and composed by cutter head part 2 and shank portion 4 integral types, cutter head part 2 and shank portion 4 arrange for front and back and are the coaxial line setting, both axis are cutter hub central axis 6, the front end of cutter head part 2 is provided with cutter groove 1, and blade 8 is set in the cutter groove 1, cutter groove 1 and blade 8 corresponding settings, blade 8 arranges around cutter hub central axis 6 uniform intervals, so cutter groove 1 also is to arrange around cutter hub central axis 6 uniform intervals.The central axis of each blade 8 relative cutter hub is obliquely installed, and is inclination along clockwise direction around all blades 8 that cutter hub central axis 6 tilts.Each blade 8 homogeneous phase tilts 18 ° to cutter hub central axis 6, like this, the cutting edge that extends vertically that is positioned at the cutter hub side on each blade 8 also departs from cutter hub central axis 6 and tilts 18 °, and namely to have the negative axial cutting edge inclination α with cutter hub central axis 6 be 18 ° to this cutting edge.Like this, when cutting, smear metal is discharged forward, be unlikely to abrade machined surface, can improve the crudy in hole.After blade 8 was obliquely installed, 18 ° the front and rear side of blade 8 sides of thereupon tilting was 2mm along vertical interval L.Described blade 8 is welded in the cutter groove 1, so be used for also 18 ° of the corresponding inclinations of a groove face of the cutter groove 1 of welding blade 8.
Described shank portion 4 is round table-like to after-contraction, and the rear end of cutter head part 2 is provided with the border and extends the outer rear end face 3 of handle of a knife round platform front end.Rear end face 3 is plane radially.Like this, cutter has improved machining accuracy and working efficiency by the conical surface on the round platform of shank portion 4 and described rear end face 3 dual location.
Establish central water flooding hole 7 in the cutter head part 2, shank portion 4 is provided with the bolt hole 5 that is communicated with central water flooding hole 7.Central water flooding hole 7 is cutter hub central axis 6 with the axis of bolt hole 5.Bolt hole 5 is of a size of M8 * 1, in bolt hole 5 by the assembling screw connecting the anchor clamps of clamping cutter, the screw tension round platform conical surface and rear end face 3 are connected with anchor clamps.Certainly, pass through central water flooding hole 7 for making cooling water, screw also should be provided with for the through hole that connects cutter head part 2 central water flooding holes 7.
Conelet shaft chisel described in the utility model, easy to process, chip removal is smooth, and aperture size is stable, and steering capability is good, the cutter good rigidly.The surface smoothness in hole and precision improve, and the cylindricity in hole improves, and the aperture variation is few, and labour intensity reduces.
Certainly, the utility model is not limited to above-mentioned form, the relative cutter hub central axis 6 of blade 8 tilt 17 ° 30 '-18 ° 30 ' between all can.
