Background technology
Engine cam shaft hole thrust surface is mainly used in installing camshaft thrust sheet, and engine cam thrust plate plays
Cam shaft is to the effect supported, and while ensureing that camshaft circumferentially rotates, stops camshaft axial float, therefore camshaft
The processing of hole thrust surface is most important, and the crudy quality of thrust surface is directly connected to the installation quality of thrust plate, indirectly
Have influence on the performance quality of electromotor.Camshaft hole is attached together by camshaft base and flap and forms, in the actual course of processing, for protecting
Card crudy need to first attach together post-treatment.
The processing method of a kind of typical camshaft hole thrust surface, for using boring cutter boring, is specially substep processing thrust
Face, carries out the side roughing of camshaft hole thrust surface first by boring cutter, and then workpiece rotates 180 °, carries out another with boring cutter
The boring processing of side thrust surface.
But, owing to the overhanging of boring cutter is long, and the impact of boring cutter bar self gravitation, after cutter rotates, cutter
Beating big, the thrust surface after processing is big with the perpendicularity of camshaft hole axis, and processing dimension is unstable, machined surface quality
Difference, has a strong impact on the installation quality of thrust plate, thus affects the performance of electromotor；Camshaft hole thrust surface is two sides, is both needed to
Being processed, side can directly utilize boring cutter and carry out machining, but opposite side is due to the impact of other flaps, therefore needs
The overhanging wanting boring cutter is the longest, and the difficulty of processing is very big, and stability is very poor.
Therefore, how to improve working (machining) efficiency and the crudy of camshaft hole thrust surface, be that those skilled in the art are current
The technical issues that need to address.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of camshaft hole thrust surface process tool, improve camshaft hole
The working (machining) efficiency of thrust surface and crudy.
For achieving the above object, the present invention provides following technical scheme:
A kind of camshaft hole thrust surface process tool, including:

View；Fig. 2 to Fig. 4 is followed successively by the specific embodiment of camshaft hole thrust surface process tool provided by the present invention and starts rotation at cutter
The structural representation that indexing is put, the structural representation in working angles and cutting the structural representation of position.
In a kind of specific embodiment of camshaft hole thrust surface process tool provided by the present invention, including cutter hub 8 and blade
2, cutter hub 8 is arranged on the side of rotating shaft 3, and can rotate with rotating shaft 3, and meanwhile, cutter hub 8 can be carried out relative to rotating shaft 3
Moving radially, wherein, rotating shaft 3 can be the main shaft of motor, lathe etc., and to drive cutter hub 8 revolution to rotate, blade 2 is for same
Time roughing camshaft hole both sides thrust surface 1, what blade 2 was sequentially arranged on the perisporium of cutter hub 8 vertically first presets contour
Presetting on contour with second, wherein, first presets point identical with a fixed point axial distance on the perisporium that contour is cutter hub 8 connects
Circumferential line, second presets contour herewith manages, and is adding man-hour, and two thrust surfaces 1 are located at first and are preset contour and second pre-
If between contour, cutter hub 8 and blade 2 around the shaft 3 central shaft carry out gyration.
It should be noted that herein axial, circumferential, radially on the basis of the central shaft of rotating shaft 3.
When being processed, the radial dimension of the cutter hub 8 of selection should be less than the radial dimension of camshaft hole.Cutter hub 8 is put
In camshaft hole, two thrust surfaces 1 are located in first and preset contour and second and preset between the point of a knife of the blade 2 on contour.
When starting position, rotating shaft 3 rotates, and drives cutter hub 8 to rotate with blade 2, and is carried out two thrust surfaces 1 slightly by blade 2 simultaneously
Processing, in working angles, cutter hub 8 moves radially relative to rotating shaft 3, with regulate between point of a knife and the centre of gyration away from
From, make point of a knife can cut thrust surface 1 from inside to outside, after having cut, cutter hub 8 carries out reverse moving radially with withdrawing；?
After roughing, respectively two thrust surfaces 1 can be carried out polish.
Visible, this kind of camshaft hole thrust surface process tool is processed while can realizing two thrust surfaces 1, is conducive to contracting
Subtracting process time, improve working (machining) efficiency, meanwhile, while two thrust surfaces 1, processing can reduce cutter hub 8 jumping when rotated
Dynamic, the stability of cutter hub 8 is preferable, advantageously ensures that crudy.
In above-described embodiment, first presets contour and second presets and can be respectively equipped with a blade 2, Mei Gezhi on contour

Make the spacing needed for point of a knife spacing regulation extremely processing, i.e. complete the regulation of point of a knife distance, arrange simple and reliable, easy to operate.
Specifically, the face that regulating block 7 contacts with blade 2 can be plane, accordingly, blade 2 contacts with regulating block 7
Face it can also be provided that plane, to ensure that blade 2 adds the stability in man-hour.Certainly, face regulating block 7 contacted with blade 2
And on blade 2 corresponding face it can also be provided that arcwall face, zigzag face or the face of other shapes.Certainly, regulation parts
Set-up mode be not limited to each embodiment above-mentioned, such as, regulation parts can also connect stretching of two blades 2 respectively for two ends
Contracting bar.
In each embodiment above-mentioned, cutter hub 8 specifically can include semicylinder and the planar side being connected to semicylinder
Character cut in bas-relief body, the inner side of character cut in bas-relief body is located at relatively by two blades 2.Wherein, the radial section of semicylinder is that angle is less than 360
The sector of degree, this angle can not be 180 degree.The arranging of semicylinder can reduce the friction probability of cutter hub 8 and camshaft hole,
Meanwhile, two blades 2 are arranged on the inner side of character cut in bas-relief body, are conducive to improving the stability of blade 2.Certainly, the shape of cutter hub 8 sets
Put and be not limited to this.
In each embodiment above-mentioned, the axial cross section of blade 2 is rhombus, and character cut in bas-relief is physically provided with for accommodating blade 2
The arcuate groove 5 of rib, when blade 2 carries out rotating to regulate point of a knife distance, the rib that blade 2 is close to cutter hub 8 turns in arcuate groove 5
Dynamic, the friction between cutter hub 8 and blade 2 can be reduced, be conducive to the service life extending blade 2 with cutter hub 8.
In each embodiment above-mentioned, on semicylinder, the side near character cut in bas-relief body is provided with depressed part 6, to reduce further
Friction probability between semicylinder and camshaft hole, extends the service life of cutter hub 8, meanwhile, alleviates the weight of cutter hub 8.
In each embodiment above-mentioned, one end of cutter hub 8 can be eccentrically provided with handle of a knife 4, and cutter hub 8 is by handle of a knife 4 connection rotating shaft
3, the central shaft of cutter hub 8 is parallel to the central shaft of handle of a knife 4.It is to say, handle of a knife 4 is the connector between cutter hub 8 and rotating shaft 3.
Eccentric setting can facilitate cutter hub 8 to pass in and out camshaft hole, has reduced the moving radially of cutter hub 8 during thrust surface 1 processing
Total distance.Specifically, handle of a knife 4 can be one-body molded with cutter hub 8, to ensure to be connected between handle of a knife 4 with cutter hub 8 reliably.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment, identical similar portion sees mutually.
