Processing, polishing cannot improve the dimensional accuracy or geometrical precision of workpiece, but be to obtain smooth surface or bright luster
Purpose, sometimes also eliminating gloss.
There are rolling process and heat treatment (vacuum annealing) process in the production process of metal tube, due to after rolling,
The inner wall of metal tube, which inevitably leaves, hinders the bright and clean smooth slight flaws of inner wall, and due to after heat treatment, metal tube
Often entire body is attached with one layer of rubbish i.e. dirt to interior inner wall, therefore need to remove flaw and rubbish.
The flaw and heat treatment procedure that the prior art generally leaves rolling process in a manner of handwork by worker stay
Under dirt handled, if do not chatted or the bar or stick of other grinding materials stretches into metal tube using being enclosed with, make bar or
Friction achievees the purpose that polishing to stick back and forth in metal tube.
At least there is following technical problem in the above-mentioned polishing mode to inner wall of metal tube：First, operating efficiency is low and worker
Labor intensity it is big；Second is that polishing effect is poor, it is difficult to quality of finish is ensured, because to inner wall of metal tube polishing when hand polish
Pressure is difficult to keep constant.
Invention content
The purpose of the present invention is to provide a kind of polishing machines, and efficiency is low when manually being polished at present to inner wall of metal tube with improving
With the problem of effect difference.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of polishing machine, including rack, vertical sliding is connected with mounting base in rack, is rotatably connected to along machine in mounting base
The shaft that frame is laterally extended, shaft slidably connects sleeve outside, and several groups polishing mechanism is equipped between shaft and sleeve, several
Group polishing mechanism is circumferentially distributed along shaft, and every group of polishing mechanism includes the polished part that several are axially distributed along shaft, each
Polished part includes polishing plate and several equal lengths and connecting rod parallel to each other, and connecting rod one end is hinged on the outer circle of shaft
The upper, other end is hinged on the polishing plate, and the through-hole passed through for connecting rod is offered on the side wall of sleeve；Machine below sleeve
Frame is equipped with pipe fitting holding tank, and pipe fitting holding tank rack is laterally extended, and vertical sliding is connected with block in the rack above sleeve,

And since polishing plate is when moving in a circle, constant is remained to the pressure energy of inner wall of metal tube, therefore is polished high-quality.
2, it is slided in sleeve by making shaft, the vertical range between polishing plate and shaft axis can be made to change,
Adapt to the metal tube of different inner diameters.
3, it when shaft is slided in sleeve, although the angle between each connecting rod and shaft axis is changing, throws
Tabula rasa can remain parallel with shaft axis, and the angle of polishing plate does not change, that is, ensure that polishing plate to metal tube
The pressure of inner wall is consistent.
4, when the metal tube to different inner diameters is polished, by transmission mechanism make supports block remain with it is to be processed
The axis of metal tube overlaps, and countershaft axis needs the difference in height adjusted to judge, convenient for making the axis and shaft of metal tube
Axis remain coincidence so that each polishing plate can be bonded with inner wall of metal tube.
