Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the present invention is further illustrated:
As shown in Figs. 1-2, thimble helicla flute automatic grinding device of the present invention, including cutting wheel 2 and setting are being cut
Cut the mounting base 3 of 2 front of wheel.Because cutting wheel 2 only does clockwise rotation, without forward travel, and thimble 1 needs two
Direction athleticism realizes that spiral-shaped slot processing, i.e. rotary motion add forward travel.In order to be given to the effect of this advance
Power needs thimble 1 to deviate an angle A and puts, as shown in figure 3, thimble 1 is T by the active force of cutting wheel 2, counterclockwise
Direction, by force resolution, decomposition obtains two power: the power T*sin (A) of the direction of advance and power T*cos (A) rotated counterclockwise,
Move thimble 1 to the two directions simultaneously, to process helicla flute.Therefore mounting base 3 and cutting wheel 2 are deviated
Certain angle (i.e. angle A) is put, and 1 clamping of thimble can be realized to mounting base 3 and be angularly offset (i.e. angle with cutting wheel 2
Spend A).Mounting base 3 includes left clamping part 31, right clamping part 32 and the upper clamping part 33 for forming clamping to thimble 1 jointly, makes thimble
1 tail surface is just aligned the bottom cut surface of cutting wheel 2.
As shown in figs. 4-7, left clamping part 31 includes left seat 311, the first rolling wheel support 312 and the first spiral roller 313, the
One rolling wheel support 312 includes the first roller attachment portion 3121 and the first guide rod 3122 being vertically connected with, the first spiral roller 313
The first roller attachment portion 3121 is mounted on by roller bearing and nut.The first guide groove 314, the first guide rod are equipped in left seat 311
3122 are mounted in the first guide groove 314 and can slide up and down.The build-up tolerance of left seat 311 is 0 to 0.02.In order to which structure is more steady
Gu the first guide rod 3122 is at least equipped with two, therefore the first guide groove 314 in bottom of the first roller attachment portion 3121 or so
Left and right is equipped with two.It is equipped with and consistent first spring groove 315 in 314 direction of the first guide groove, the first spring groove 315 in left seat 311
Inside it is equipped with the first spring 316, the bottom connection touching at the top of the first spring 316 and the first roller attachment portion 3121.First spring
Slot 315 and the first spring 316 are preferably provided two, smoothly withstand the first rolling wheel support 312, can be with the top of clamping different-diameter
Needle 1.First spring 316 selects Hookean spring, and a diameter of 1.2mm, outer diameter 12mm, dynamics is little, precompressed 2mm, only needs
Thimble 1 is slightly lived surely, and thimble 1 can also be travelled forward.
Right clamping part 32 includes right seat 321, the second rolling wheel support 322 and the second spiral roller 323, the second rolling wheel support
322 include the second roller attachment portions 3221 and the second guide rod 3222 that are vertically connected with, the second spiral roller 323 by roller bearing and
Nut is mounted on the second roller attachment portion 3221.It is equipped with the second guide groove 324 in right seat 321, the second guide rod 3222 is mounted on the
In two guide grooves 324 and it can slide up and down.The build-up tolerance of right seat 321 is 0 to 0.02.In order to which structure is more firm, the second guiding
Bar 3222 is at least equipped with two in bottom of the second roller attachment portion 3221 or so, therefore also left and right is equipped with two to the second guide groove 324
Item.Be equipped in right seat 321 with the consistent second spring slot 325 in 324 direction of the second guide groove, be equipped with second in second spring slot 325
The bottom connection of spring 326, the top of second spring 326 and the second roller attachment portion 3221 touches.Second spring slot 325 and second
Spring 326 is preferably provided two, smoothly withstands the second rolling wheel support 322, can be with the thimble 1 of clamping different-diameter.Second bullet
Spring 326 selects Hookean spring, and a diameter of 1.2mm, outer diameter 12mm, dynamics is little, precompressed 2mm, only slightly need to live to push up surely
Thimble 1 can also be travelled forward for needle 1.
Upper clamping part 33 includes panel 331, third rolling wheel support 332 and third spiral roller 333, third rolling wheel support
332 are mounted on the bottom of panel 331 by screw, and third spiral roller 333 is mounted on third rolling wheel support 332 by roller bearing
On.
The both ends of first spiral roller 313, the second spiral roller 323 and third spiral roller 333 are mounted on bearing 34,
Allow spiral roller energy ease rotation.The helicla flute of first spiral roller 313, the second spiral roller 323 and third spiral roller 333
It is tied with adhesive tape 35 above, the prominent spiral roller surface 1mm of adhesive tape 35 increases frictional force, to make spiral roller by thimble 1
Drive move together, smoothly support thimble 1 and process beautiful helicla flute.
In order to facilitate clamping, the upper end of the left end of panel 331 and left seat 311 is hinged by shaft, the right end of panel 331 and
By lock connection, the lower end of left seat 311 and the lower end of right seat 321 are fixed by screws for the upper end of right seat 321.
In order to facilitate movement, mounting base 3 is mounted on pedestal 4 by screw, and pedestal 4 is parallel with cutting wheel 2.
Installation method of the invention:
