Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a curved chamfer apparatus for a throttle shaft includes: chassis 1, chassis 1's upper end fixed mounting has retainer plate 2, the spout with 13 looks adaptations of movable rod is seted up to retainer plate 2's upper surface, retainer plate 2's last fixed surface installs solid fixed ring 3, gu fixed ring 3's inside seted up with the movable groove of 5 looks adaptations of driven gear, milling cutter 4 has been cup jointed at the middle part of retainer plate 2 upper surface, milling cutter 4's lower extreme runs through and extends to chassis 1's inside fixed mounting has the servo motor output shaft, chassis 1's inside fixed mounting has servo motor, gu fixed ring 3's inside movable mounting has driven gear 5, driven gear 5 is located solid fixed ring 3's inside and is the equidistance and arranges, driven gear 5 all is located the below of stationary blade 10 with driving gear 6, and driven gear 5 can not influence the chamfer of door-hinge with driving gear 6's rotation, driven gear 5 tooth department meshing has driving gear 6.

Wherein, use through milling cutter 4, driven gear 5 and driving gear 6's cooperation, imitated that the staff is manual to hold the door-hinge and carry out the curve chamfer, can drive around the door-hinge lower extreme, the curve chamfer of carrying on at no dead angle of a little.

Driving gear 6's last fixed surface installs rotary column 7, rotary column 7 upper end movable mounting has fixed disk 8, movable slot 11 of seting up on the fixed disk 8 is clockwise spiral inwards, mainly be for conveniently receive and release stationary blade 10, movable slot 11 has been seted up to the upper surface of fixed disk 8, movable slot 11's inside slidable mounting has connecting rod 9, the one end fixed mounting that rotary column 7 was kept away from to connecting rod 9 has stationary blade 10, the impartial surface of arranging at fixed disk 8 of stationary blade 10, and the diameter that the stationary blade 10 encloses into the circle is not more than the distance of milling cutter 4 to solid fixed ring 3 inner wall, the last fixed surface of fixed disk 8 installs turning block 12, driving gear 6's lower extreme movable mounting has movable rod 13, the lower extreme of movable rod 13 and the last surface slidable mounting of retainer.

Wherein, through fixed disk 8, connecting rod 9, the stationary blade 10, the commentaries on classics piece 12 of activity groove 11 uses, can be convenient and firm fixed the door-hinge, do not need the manual holding of staff, just can carry out curve chamfer with the door-hinge, owing to do not need the manual holding of staff, guaranteed that staff's hand is when carrying out curve chamfer for the door-hinge, can not harm easily, staff's safety has been protected, and the labour has been liberated, and simultaneously, because the stationary blade 10 is adjustable, it is applicable in the fixed of different door-hinges, curve chamfer's application range has been increased.

When using, cup joint the door-hinge at the surface of stationary blade 10, anticlockwise rotation changes piece 12, make 8 anticlockwise rotations of fixed disk, later connecting rod 9 has driven stationary blade 10 along with movable slot 11 and outwards extended gradually, the diameter of stationary blade 10 grow gradually, internal diameter looks adaptation with the door-hinge, thereby fix the door-hinge, start milling cutter 4 this moment, make milling cutter 4 clockwise rotate, clockwise pivoted milling cutter 4 has driven the door-hinge of cover at stationary blade 10 surface and has carried out curve chamfer, because clockwise pivoted milling cutter 4 is used in the door-hinge of stationary blade 10 surface and carries out curve chamfer's power downwards, so give stationary blade 10 decurrent power, make rotary column 7 anticlockwise rotation, thereby make driving gear 6 anticlockwise rotate on driven gear 5 in proper order, make the door-hinge lower extreme evenly by curve chamfer.
