Cutting agency includes downside cylinder and splicing track, and the bottom of splicing track is equipped with push plate, and downside cylinder stretches
Bar is fixedly connected on push plate.
Concrete operating principle: manually need the main shaft with spline of deburring toward chute feeder feed inlet put into, due to
The bottom surface of chute feeder is inclined-plane, and what main shaft can be orderly tumbles and leave discharge port into same inclined feeding track, main shaft rolling
To after the end of feeding track, enters and just keep off in the card slot 95 for getting stuck plate 92 of feeding track end.
Then 94 air inlet of lower air cylinder, telescopic rod are released, are pushed away being fixed under the plate 92 that gets stuck of telescopic rod one end, indirectly
The main shaft that gets stuck in 92 card slot 95 of plate is located at also with moving down, in order to guarantee that main shaft is not fallen, the lower part for the plate 92 that gets stuck is set
Have and hold in the palm hand 93, under the action of the spring 96 in connecting shaft between two claws, support hand 93 can be good at holding main shaft
It does not fall, is depressed at energy 96 collet of alignment springs when blanking plate is pressed down cylinder 94,
By the air inlet of right cylinder 23, at the spline for feeler gauge tentatively being pushed to main shaft, and in 96 collet of main shaft propelling spring,
Enable 96 collet clamping spindle of spring.
When the main shaft of feeding track end moves down in order to guarantee the latter main shaft in the case where no card slot 95 is clamped
It does not fall, nor affects on the main shaft moved down, extend blend stop vertical out at the top for the plate 92 that gets stuck, ensure that and moving down
Main shaft normally move down, while the main shaft on feeding track is not fallen.
After the main shaft of elastic collet clamping band spline, lower air cylinder 94 moves back gas, and telescopic rod is flexible, gets stuck on plate 92
It moves, due to the blocking of main shaft, hand 93 is ask to be located at the lower section of main shaft again, cannot make that hand 93 is ask to move up well, so the company of being provided with
Extension bar makes claw and the rotation connection found a place to live in, allow claw and hold in the palm the angle of hand 93 from acute angle when holding in the palm main shaft become with
Find a place to live in and move up and find a place to live in gradually at obtuse angle, so that claw is turned to the top of main shaft, while the elastic potential energy handle of spring 96
Inclined claw retracts original state below main shaft.
Clamp system is exactly the function of playing clamping spindle, two one 11 air inlets of left hand cylinder, corresponding telescopic rod top
Out, fixed plate 2 17 moves backward, and fixed plate 2 17 will compress the elastic slice 15 of opening into rotation axis 13, realizes rotation axis
The purpose of the main shaft of the 96 collet clamping band spline of spring of 13 other ends.
Secondary push-tight portion carries out formal deburring operation, i.e. servo motor 24 rotates, and drives lead screw 25 to rotate, mobile station 26
Change in displacement occurs under the position-limiting action of cavity workbench and under the drive of lead screw 25, to realize the shifting of platen 1
Dynamic, when platen 1 is mobile towards clamp system direction, the Qian shape bayonet 27 on platen 1 will be on the outer wall edge of feeler gauge
The length direction of feeler gauge advance, it is further mobile toward clamp system direction the feeler gauge of one end distance has been pushed out, make to lead
Spline on axis can fully enter feeler gauge, this process can get rid of the burr in shallow slot.
Meanwhile it being additionally provided with detection device in the feeler gauge, spline is pushed by the advance of feeler gauge by feeler gauge, if on spline
The depth requirements and feeler gauge of shallow slot mismatch, and equipment will alarm, and deburring movement also no longer goes on.
If detection is correct, secondary deburring is also carried out after a deburring, i.e. 18 air inlet of rotary cylinder drives rotation
Bar rotation so that master gear 19 be driven to rotate, and is driven from gear 20 by belt and is rotated, fixed from gear 20 and rotation axis 13
Connection finally drives 96 collet of the spring rotation being fixedly connected with 13 other end of rotation axis, realizes quilt so that rotation axis 13 rotates
The main axis with spline that 96 collet of spring clamps carries out the shallow slot of spline and the secondary corresponding matching of feeler gauge, carries out another
Secondary deburring, twice deburring make the burr in spline keyway remove more thorough.
After the completion of deburring, left hand cylinder 1 moves back gas, and fixed plate 2 17 moves forward, and the elastic slice 15 in compressive state does not have
It is compressed, will flick by fixed plate 2 17,96 collet of spring will unclamp the main shaft with spline, positioned at the left side of middle
2 12 air inlet of cylinder, telescopic rod are released, and the mandril at 13 middle part of rotation axis are promoted in rotation axis 13, the other end of mandril will
The spline spindle for removing burr well is released, left hand cylinder 2 12 moves back gas, and telescopic rod retracts, and mandril does not have the thrust of telescopic rod
Will auto-extending rotation axis 13 one end, convenient for the propulsion again of next left hand cylinder 2 12.
Meanwhile downside cylinder intake, telescopic rod ejection push splicing rail base to advance equipped with push plate, splicing track
One end will reach the lower section for having removed the main shaft of burr, main shaft is fallen on splicing track, and downside cylinder moves back gas, stretch
Bar retracts, and push plate can also retract, and splicing track and then retracts together, and splicing track is to be obliquely installed, and main shaft will be rolled down to and be connect
In hopper.
As long as the operation of the spline deburring on next main shaft, which repeats above operation, to be completed, so recycles, just can
Complete the removal of burr on spline.
By the cooperation of said mechanism, the deburring operation with main spindle multiple spline may be implemented, there is automatic charging, it is automatic to press from both sides
Tightly, automatically removing burr and the advantages of automatic blanking, the artificial investment of reduction improves the efficiency of deburring, reduces labour
Intensity, and improve processing efficiency.
In addition to this, in step S6, using the feeding mechanism 8, feed mechanism 9 and clamp system of deburring equipment to main shaft
It is fixed, then processed using lathe tool.Similarly, it solves that main shaft is manually placed on the inconvenience on process equipment, to a certain degree
The upper intensity for reducing staff.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
