[background technology]
Known, at present, in the machining production process, the knife bar that does not have the radial feed motion mostly has the multiple oblique Xie formula that biases toward.Its operation principle is as follows: boring coaxial aperture system uses long boring cutter bar, one end inserts spindle taper hole, the other end passes through the workpiece preprocessing hole and is supported by the tail column, main shaft drives the boring cutter revolution and does main motion, workbench drives workpiece and does the length feed motion, can bore identical (two) coaxial aperture of diameter, the hole method that the single degree of depth of boring is big is identical therewith.
There is following deficiency in said method:
1, knife bar is longer, makes comparatively trouble.
2, calculate, use and install and adjust effort, and drop into bigger.
3, it is lower to move slower, relative efficient for processing in enormous quantities; And on drilling machine acomia complete operation.
For above-mentioned reasons, so caused present cutter can only use special holder and special purpose machine tool; There is not versatility.Especially for the processing that a kind of hole slot is arranged in the locomotive fittings,, utilize the fine setting eccentric disc feed of existing method because this part belongs to non-rotating class workpiece.Each tool setting, length and diameter are all wayward.
[summary of the invention]
In order to overcome the deficiency in the background technology, the utility model discloses a kind of endoporus cannelure sizing knife bar, described endoporus cannelure sizing knife bar has been realized autofeed, automatic spacing; Mechanism described in the utility model not only significantly increases work efficiency, and in use need not artificial constant size, and has advantages such as one-shot forming.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions:
A kind of endoporus cannelure sizing knife bar comprises socket for taper shank, spring, nut, eccentric loop bar, sliding pin, stop nut, interstage sleeve, bearing, cutter spindle and cutter head; One end of described socket for taper shank is provided with connector, the other end is a tubular structure, be provided with a spring putting hole less than outside diameter in tube, a side of described eccentric loop bar is inserted in the outside diameter of tube and omits general goal, and is withstood on the slip cotter way upper limit of described cutter spindle by the sliding pin that is located at slotted eye; Cutter spindle is arranged in the interior eccentric inner hole of eccentric loop bar, the cutter spindle end disk of cutter spindle one end is enclosed within the screw of eccentric loop bar, by the nut shutoff, the outer end of described spring withstands on nut one side in the screw of a lateral deviation heart loop bar of cutter spindle end disk; Opposite side outer rim at eccentric loop bar is provided with the interstage sleeve connecting ring, and interstage sleeve socket interstage sleeve connecting ring is provided with bearing in interstage sleeve; Described cutter head is arranged on the other end of cutter spindle.
Described endoporus cannelure sizing knife bar, the sliding pin outer setting that is located at slotted eye has stop nut.
Described endoporus cannelure sizing knife bar, the tube matched in clearance of eccentric loop bar and socket for taper shank one end.
After adopting technique scheme, the beneficial effect that the utlity model has is:
Endoporus cannelure sizing knife bar described in the utility model has been realized autofeed, and automatic spacing reaches the figure paper size fully, and the utility model adapts to the porous sizing of boring machine, drilling machine, becomes the processing of hole slot in the size; Mechanism described in the utility model not only significantly increases work efficiency, and in use need not artificial constant size, and has advantages such as one-shot forming.

[specific embodiment]
With reference to the following examples, can explain the utility model in more detail; But should be noted that the utility model is not limited to following embodiment.
Endoporus cannelure sizing knife bar described in Fig. 1～5 comprises socket for taper shank 1, spring 2, nut 3, eccentric loop bar 5, sliding pin 6, stop nut 7, interstage sleeve 8, bearing 9, cutter spindle 10 and cutter head 11; One end of described socket for taper shank 1 is provided with connector, the other end is a tubular structure, in tube, be provided with spring 2 putting holes less than outside diameter, one side of described eccentric loop bar 5 is inserted in the outside diameter of tube and omits general goal, and is withstood on slip cotter way 16 upper limits of described cutter spindle 10 by the sliding pin 6 that is located at slotted eye 13; Cutter spindle 10 is arranged in the eccentric inner hole 15 in the eccentric loop bar 5, the cutter spindle end disk 4 of cutter spindle 10 1 ends is enclosed within the screw 12 of eccentric loop bar 5, by nut 3 shutoff, the outer end of described spring 2 withstands on nut 3 one sides in the screw 12 of a lateral deviation heart loop bar 5 of cutter spindle end disk 4; Opposite side outer rim at eccentric loop bar 5 is provided with interstage sleeve connecting ring 14, and interstage sleeve 8 socket interstage sleeve connecting rings 14 are provided with bearing 9 in interstage sleeve 8; Described cutter head 11 is arranged on the other end of cutter spindle 10; Sliding pin 6 outer setting that are located at slotted eye 13 have stop nut 7; The tube matched in clearance of eccentric loop bar 5 and socket for taper shank 1 one ends.
Implement endoporus cannelure sizing knife bar described in the utility model, described centering type endoporus annular groove lever structure is in conjunction with shown in Figure 1, and socket for taper shank 1 inserts " drilling machine or boring machine do not show among the figure " in the main shaft; Interstage sleeve 8 and thrust bearing 9 are stuck on the interstage sleeve connecting ring 14 of eccentric adjusting sleeve 5 by back-up ring 8, be provided with unthreaded hole and screw thread in the eccentric loop bar 5 with certain offset, described screw thread place is screw 12 " Fig. 2 ", and nut 3 tightly is pressed in the eccentric screwhole 12 of eccentric loop bar 5 by the termination center screw 12 usefulness balls 17 of cutter spindle 10; Cutter spindle 10 can not be made axial float in eccentric orfice, and can only rotate.
During use, move axially while main shaft drive socket for taper shank 1 rotates, interstage sleeve 8 leads are advanced into earlier and prop up workpiece end face in the hole, and at this moment, interstage sleeve 8 stops eccentric loop bar 5 to continue descending by bearing 9; Spring 2 is compressed by socket for taper shank 1 and tightly is pressed in eccentric loop bar 5 end faces, and cutter spindle 10 just is being with cutter head 11 to carry out cutting movement.
Motion described in the utility model is to pass eccentric loop bar 5 by sliding pin 6 to stir cutter spindle 10 along helicla flute 18 brute forces of not self-locking and do and be synchronized with the movement and cut.The feeding limit is to be adjusted the silk restriction; When cutter spindle 10 behind certain stroke, cutter head 11 is cut to size, cutter spindle 10 stop motions at this moment, and cutter spindle 10 rollbacks, powerful sliding pin 6 crossheadings spur eccentric loop bar 5 and cutter spindle 10 revolutions, make cutter head 11 withdraw from bottom land, finish cutting.
The embodiment that selects for use in this article for open the purpose of this utility model currently thinks to suit, but will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the interior embodiment of this design and the utility model scope.
