A kind of chamfering method of the radial direction circular hole of pipe outer peripheral face
Technical field
The present invention relates to machining field, and in particular to a kind of chamfering method of the radial direction circular hole of pipe outer peripheral face.
Background technology
Radial direction circular hole on current pipe outer peripheral face(Radial direction circular hole refers to the circular hole that axis is radially extended along pipe)'s
The chamfering method of external port generally or using the chamfering method of plane circular hole carries out chamfering, i.e., stretch into radially circle using rose reamer
In hole, chamfering is carried out to the external port of radial direction circular hole by the rotation of chamfering.As shown in Fig. 2 because the outer peripheral face of pipe 9 is cylinder
The external port edge of radial direction circular hole 9.1 on face, pipe outer peripheral face is not in a plane, and rose reamer is stretched on pipe outer peripheral face
Radial direction circular hole in carry out chamfer machining, rose reamer to the cutting output at the external port edge of the radial direction circular hole on pipe outer peripheral face not
Unanimously, rose reamer is maximum to the cutting output of the high site location at the external port edge of radial direction circular hole, and the circle on pipe outer peripheral face
The cutting output of the low points position at the external port edge in hole is minimum, causes the chamfering uniformity of the radial direction circular hole on pipe outer peripheral face
It is very poor.

Down;
Then, drive vertical guide rod to move up, round orifices orientation post is inserted in the radial direction circular hole of pipe outer peripheral face, make pipe outer peripheral face
Radial direction circular hole axis and vertical rose reamer axis coaxle;
Followed by, pipe is fixed on by tubing lock-screw and is horizontally mounted on axle sleeve, then, drives vertical guide rod to move down,
Round orifices orientation post is set to be located at below pipe;
Second, axle sleeve motor drives pipe rotation 180 degree, makes the radial direction circular hole of pipe outer peripheral face upward;
3rd, rose reamer motor drives vertical rose reamer rotation;Meanwhile, lifting executing agency drives vertical rose reamer to move down
In place, vertical rose reamer starts to carry out chamfering to the external port of the radial direction circular hole of pipe outer peripheral face;
4th, axle sleeve motor drives pipe to turn clockwise set angle β, and then, axle sleeve motor is stopped;Connect
, axle sleeve motor drives the β of pipe rotate counterclockwise set angle 2, and then, axle sleeve motor is stopped;So as to complete
The chamfering of the external port of the radial direction circular hole of paired pipe outer peripheral face;
5th, rose reamer motor is stopped, and lift cylinder drives vertical rose reamer to move up, reset.
The chamfering method of the radial direction circular hole of the pipe outer peripheral face of this programme is not only easy to process, can effectively ensure that outside pipe
The chamfering uniformity of radial direction circular hole on side face, and required equipment(Beveler)It is simple in construction, low manufacture cost.
Preferably, round orifices orientation post is connected through a screw thread with vertical guide rod upper end.This programme structure can be as needed
Change round orifices orientation post.
Preferably, axle sleeve motor is stepper motor or servomotor.
It is coaxially disposed preferably, being horizontally mounted axle sleeve with horizontal rotating shaft.
Preferably, lifting executing agency is lift cylinder or lifting electric cylinders.
The beneficial effects of the invention are as follows:It is not only easy to process, it can effectively ensure that radial direction circular hole on pipe outer peripheral face
Chamfering uniformity, and required equipment(Beveler)It is simple in construction, low manufacture cost.

Fig. 2 is a kind of structural representation of pipe of the prior art.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings:
As shown in figure 1, a kind of chamfering method of the radial direction circular hole of pipe outer peripheral face, including beveler.
Beveler include frame 2, be arranged in frame vertical guide pillar 3, along vertical guide pillar lift mounting platform 5, set
Put in frame be used for lift mounting platform lifting executing agency 1, be rotatably arranged on mounting platform vertical rose reamer 6,
Being arranged on mounting platform is used to rotate the rose reamer motor 4 of vertical rose reamer, is arranged in frame and flat positioned at installing
Round orifices orientation mechanism 7 below platform and it is arranged on tubing installing mechanism 8 in frame and below mounting platform.Lifting is performed
Mechanism is lift cylinder or lifting electric cylinders.
