Three patent documentations mentioned in present context technology are the former apllied patent of applicant, although also can
Improve working (machining) efficiency, but applicant thinks that the amplitude that working (machining) efficiency improves is not the most very big, if carried out it further
Improving, the working (machining) efficiency of pipeline end facing machine still has the space of raising further.Therefore, applicant sends out through careful research
Now, upper, discharging processing method in patent documentation one (CN103551639A) are: lower clamp first moves to feeding position and carries out
Feeding, after feeding completes, controls lower clamp and drives pipe fitting to be processed to move to Working position, then control to press under upper fixture with under
Fixture coordinates pipe fitting clamping, then is processed pipe fitting, after machining, then controls to move on upper fixture to unclamp the folder to pipe fitting
Tightly, then control lower clamp drive machined complete pipe fitting move towards feeding position together, owing to lower clamp is Split type structure,
During movement, control lower clamp separately, the discharge so that the machined pipe fitting completed drops from lower clamp, machined
After the pipe fitting completed is discharged, lower clamp moves back again to feeding position and carries out feeding next time.Visible, at this patent documentation
In, when feeding, processing and the discharging of pipe fitting separately complete, a pipe fitting needs to have carried out successively feeding, processing and discharging
After three steps, could operate next pipe fitting, i.e. when previous pipe fitting operates, later pipe fitting is located always
In waiting state, thus extend the process time of pipe fitting, reduce the working (machining) efficiency of pipeline end facing machine.
In patent documentation two (CN104907879A), mainly devise a kind of feeding device, pipe fitting to be processed is sent
Enter in lower clamp, but on it, discharging processing method or and patent documentation one (CN103551639A) in upper, discharging processing
Method is the same, and the feeding of pipe fitting, processing and discharging separately complete, when the most previous pipe fitting operates, and later pipe
Part is constantly in waiting state.

Clamped pipe fitting to be processed is carried out tack, and after tack completes, the unit head 6 with cutter head reversely moves back in situ, on
Fixture 5 reversely moves the clamping of the pipe fitting unclamped in the lower clamp two being pointed at Working position B and returns in situ, thus completes to add
Work operates;The lower clamp 34 moved by Working position B moves to discharge position C, is being acted on by inertia and gravity
Under, the pipe fitting processed in mobile lower clamp three to discharge position C is from mobile lower clamp 34 to discharge position C
In be thrown out of, thus complete discharging operations, wherein, feeding operation, process operation and discharging operations complete simultaneously;
When feeding operation, process operation and discharging operations complete after simultaneously, control transmission band 1 and again move, so that feeding
Lower clamp 1 at the A of position moves towards Working position B, and the lower clamp 23 at Working position B moves towards discharge position C, discharging
Lower clamp 34 at the C of position moves towards feeding position A, thus repeats the operation of above-mentioned feeding, process operation and discharging operations.?

Embodiment 2: as it is shown in figure 9, compared with Example 1, difference is: the side of fixture 5 is arranged on described
Anti-blockage mechanism, Anti-blockage mechanism is had to include contiguous block 37, stage clip 38 and jacking block 39;Contiguous block 37 is arranged on the one of fixture 5
Side, one end of stage clip 38 is connected with contiguous block 37, and the other end of stage clip 38 is connected with jacking block 39, when upper fixture can add with being positioned at
The lower clamp of work position match the pipe fitting clamping in the lower clamp that will be located at Working position time, jacking block 39 connects with pipe fitting
Touching, stage clip 38 is in and press-fits state.Tack at pipe fitting adds man-hour, presses and coordinate pipe fitting with lower clamp under needing due to upper fixture
, therefore, when machining on upper fixture after shifting, often there is the phenomenon that pipe fitting is clamped in fixture, be referred to as upper card in clamping
Material, after phenomenon that generation gets stuck, the pipe fitting machined just cannot carry out discharging from lower clamp, thus have impact on pipe fitting tack
The working (machining) efficiency of machine, the present embodiment is by arranging Anti-blockage mechanism on upper fixture, when machining, when upper fixture moves,
Under the reset response of stage clip, utilize jacking block to be backed down by pipe fitting, thus avoid the generation of the phenomenon that gets stuck, further increase pipe
The working (machining) efficiency of part chamfering machine.
Embodiment 3: as shown in Figure 10, compared with Example 1, difference is: arrange lower clamp on the belt
Have four, respectively lower clamp 1, lower clamp 23, lower clamp 34 and lower clamp 4 40.Wherein, lower clamp 1 is positioned at
