Bracket is fixed on sliding platform.The straight line mould group, which is specifically as follows, motor-driven lead screw mould group, can also be cylinder
The slider module of promotion is not particularly limited its specific structure at this.But it should be recognized that the linear motion mould group with
Power device (motor, cylinder) junction needs that damping spring is arranged.During the polishing process due to interior throwing bar 602, will lead to
It processes tubing to vibrate for a long time, and then causes the vibration of straight line mould group, during Long-term Vibration, be easy to cause linear motion mould
Group is damaged, thus, damping spring is set in straight line mould group and power device junction, can extend straight line mould group uses the longevity
Life.
As a preferred embodiment, as shown in attached drawing 10, attached drawing 11, the ramming head 603 is made using rubber 603a, is passed through
Rubber 603a is folded back and forth, and folding in shape is circular ring shape, polygon or criss-cross ramming head 603.Wherein, preferably cross
Or its deformation, such as M shape and waveform etc..When polishing is significantly shaken, due to cross or M shape ramming head 603
For flexible structure, a degree of deformation can occur, it is not in the case where stress is concentrated that polishing force is more uniform,
More be not in the case where roughness of pipe material inner wall becomes larger, improve product quality, reduces rejection rate.In actual use process
In, the ramming head 603 of multiple flexible structures in the technical program in the specific implementation process, significantly shakes due to polishing
When, the radial shaking amplitude of interior throwing bar 602 and ramming head 603 far from belt fixing end side is greater than close to belt fixing end one
The shaking amplitude of bar 602 and ramming head 603 is thrown in side；Thus it will appear: after the completion of polishing, in the polishing area of different ramming heads 603
Roughness there are the differences of a 0.05 ~ 0.10um, and closer to belt fixing end, roughness is bigger.Therefore it is actually answering
With in the process, can suitably increase in the diameter close to belt fixing end side ramming head 603, reduce far from belt fixing end side
The diameter of the diameter of ramming head 603, i.e., the described ramming head 603 gradually becomes smaller from belt fixing end to far from belt fixing end.
Discharging mechanism is a transmission belt 7 being arranged in below the tubing sliding platform 3.It is sent to by transmission belt 7
Next workshop section is processed, and realizes discharging.
In order to facilitate the technical solution for understanding tubing polishing machine, its working principle and workflow are made briefly

S5, lifting cylinder 303 push to be moved at sliding platform 302 in lifting 304 phase of guide plate, tubing free skating to be processed
It drops down at the limited block 306b on limit assembly 306, identical as step S2, the pusher cylinder in second propulsive mechanism 4 pushes
To one end of tubing to be processed, mechanical grip 405 lives pipe clamping to be processed for the second sliding shoe 403 and catch bar 404, continues
It moves forward at inner surface polishing mechanism.
S6, when tubing to be processed moves to V-arrangement fixture 604, and be sleeved on interior throwing bar 602, release mechanism is grabbed, and
It is fixed under the cooperation of fixation kit, the second servo motor 601 drives multiple ramming heads 603 to polish in tubing internal rotating to be processed,
Meanwhile pushing V-arrangement fixture 604 and tubing to be processed to move preset distance in the horizontal direction by linear motion component 606, then
Initial position is come back to, interior polishing process is completed.
S7, mechanical grip 405 clamp tubing to be processed again, and tubing to be processed is returned at limit assembly 306, pine
Mechanical grip 405 is opened, is horizontally arranged；Then rotary cylinder 306f pushes the first sliding shoe 306e and rack gear 306d in slide rail
Upper movement, and then drive limit rotary shaft 306a and limited block 306b to rotate predetermined angular by gear 306c, until limited block 306b
Concordant with sliding platform 302, tubing to be processed is free to slide, until realizing discharging in transmission belt 7, being sent to down by transmission belt 7
One workshop section is processed.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, it can be combined in any appropriate way.In order to avoid unnecessary repetition, the present invention to it is various can
No further explanation will be given for the combination of energy.
