There is coolant, the volume of the coolant is more than the volume of the cooling duct.
When rod of polishing rotates, liner synchronous axial system is rotated, the coolant in it is under the influence of centrifugal force along in rotating
Serve as a contrast inwall on centrifugal flow groove reciprocation cycle flowing, will polishing rod on because of friction and caused by heat take away, flowing through cooling
With atmospheric environment heat-shift during passage, then it flow back into rotation liner and is cooled down again.
As the preferred of above-mentioned technical proposal, the cooling duct and the contact jaw of the rotation liner are round mouth, are set
There is seal groove, slip ring is provided with the seal groove, sealing ring is provided with outside the slip ring, when the rotation liner rotates,
The sealing ring rotates on the slip ring, and the cooling duct remains stationary as.
As the preferred of above-mentioned technical proposal, the cooling duct is circular pipeline.
As the preferred of above-mentioned technical proposal, the outer surface of the cooling duct is provided with radiating fin.
As the preferred of above-mentioned technical proposal, the centrifugal flow groove is the groove of shape of threads.
As the preferred of above-mentioned technical proposal, the polishing rod is included positioned at the first polishing portion at both ends and the second polishing
Portion, and the rotation basic point in the middle part of the polishing rod, power-equipment turn by the drive polishing rod of the rotation basic point
Dynamic impetus；The second polishing portion is more than the first polishing portion apart from the rotation apart from the distance of the rotation basic point
The distance of basic point.
The first polishing portion and the second polishing portion are the part for being applicable to different size, also can be in the too high phase of temperature
Mutually it is replaced.
As the preferred of above-mentioned technical proposal, polishing rod branch is provided between the second polishing portion and the rotation basic point
Support part, the polishing rod supporting part are socketed on the polishing rod.
The polishing rod supporting part causes rod holding stabilization when rotating of polishing.
As the preferred of above-mentioned technical proposal, the power-equipment is motor or hydraulic system.
In summary, the invention has the advantages that：
A kind of sander of circulation temperature lowering of the present invention being capable of continuous sanding operation, and avoid polishing part for a long time
High temperature influences polishing quality.
