Abstract
The invention belongs to the technical field of grinding for the interiors of pipes, and particularly discloses a polishing device for the inner wall of a stainless steel pipe fitting. The polishing device comprises a drive motor and a grinding bar and further comprises an eccentric wheel. The eccentric wheel is fixed to an output shaft of the drive motor. The grinding bar is fixed to the eccentric wheel. The distance between the rotating center of the eccentric wheel and the grinding bar is equal to the radius of the inner wall of the stainless steel pipe fitting. The grinding bar is hollow, grinding liquid is contained in the grinding bar, water outlet holes are formed in the grinding bar along the axis of the grinding bar, and a water inlet hole is formed in the end, close to the eccentric wheel, of the grinding bar. The grinding bar is made to stretch into the stainless steel pipe fitting, the eccentric wheel is driven by the drive motor to rotate and drives the grinding bar to rotate, the grinding bar is promoted to be in contact with the inner wall of the stainless steel pipe fitting, and therefore the inner wall of the stainless steel pipe fitting is ground. In addition, when the grinding bar rotates, grinding materials in the grinding bar are thrown out of the water outlet holes to impact the inner wall of the stainless steel pipe fitting under the action of centrifugal force.
Description
Technical field
The invention belongs to for grinding technique field, pipe inside, particularly relate to a kind of stainless steel pipe polishing device for inner wall.
Background technology
Stainless steel pipe has excellent mechanical performances and the characteristic such as corrosion-resistant, and be widely used in the fields such as space flight, ocean, nuclear energy, medicine equipment and petrochemical industry, aluminum pipe has good corrosion resistance, is mainly used in the fluid-transporting tubing of high-end product.In recent years, along with development and the innovation of technology, people, to the demand expanding day of stainless steel pipe, are also improving constantly the requirement of its quality.Because the roughness reducing stainless steel pipe inwall can reduce inwall to the resistance of fluid and the material effect in the absorption of inwall, so the requirement of people to stainless steel pipe inner wall roughness is more and more higher.
The method of existing reduction stainless steel pipe inner wall roughness mainly adopts the mode of machine glazed finish.Mainly polishing rod is extend in tube wall, rotated by craft or driven by motor polishing rod, polishing rod is contacted with each other with stainless steel pipe inwall, friction, thus reach the effect of inwall polishing.But pure mechanical type polishing, it is not so good that the inwall of stainless steel pipe is often polished, and often do not polish and put in place in some trickle place, causes overall polishing effect poor.
So, be badly in need of a kind of stainless steel pipe polishing device for inner wall of polishing effective.
Summary of the invention
Object of the present invention is providing a kind of stainless steel pipe polishing device for inner wall of polishing effective
In order to achieve the above object, base case of the present invention is: stainless steel pipe polishing device for inner wall, comprise drive motors and polishing rod, wherein, also comprise eccentric wheel, described eccentric wheel is fixed on the output shaft of drive motors, described polishing rod is fixed on eccentric wheel, described polishing rod can be polished to the inwall of stainless steel tube, described polishing rod is the polishing rod of hollow, is provided with lapping liquid in polishing rod, and polishing rod is provided with apopore, described apopore is along the axis distribution of polishing rod, and described polishing rod is provided with inlet opening near eccentric one end.
The principle of this base case is: stretch in stainless steel pipe by polishing rod, and drive motors band movable eccentric wheel rotates, and eccentric wheel drives polishing rod to rotate, and impels polishing rod to polish to stainless steel pipe inwall.Further, while polishing rod rotates, under the influence of centrifugal force, the abrasive in polishing rod throws away from apopore, clashes into the inwall of stainless steel pipe.
The beneficial effect of this base case is: eccentric pivot equals the inwall radius of stainless steel tube with the distance of polishing rod, when eccentric wheel drives polishing rod to rotate, polishing rod is just polished to the inwall of stainless steel tube, without the need to carrying out the contact internal walls with stainless steel tube by mobile polishing rod.When abrasive clashes into the inwall of stainless steel pipe, have good cutting, abrasive action to the inwall of stainless steel pipe, can well be polished to some polishing bastinades mills less than place, enhance polishing effect.
Scheme two: based on this, scheme is preferred, also comprises the seal cover for closed stainless steel pipe.During operation, stainless steel pipe is obliquely installed, and covers seal cover at its low side, add lapping liquid toward stainless steel pipe.When rod of polishing rotates, polishing rod has good stirring action to the lapping liquid in stainless steel pipe, produces relative motion, strengthen the grinding effect of stainless steel pipe between lapping liquid and stainless steel pipe.
Scheme three: based on this, scheme or scheme two is preferred, and described lapping liquid is polycrystalline diamond lapping liquid.Polycrystalline diamond lapping liquid has good toughness, not easily produces scuffing while can keeping high grinding force in grinding and polishing process, and grinding effect is good.
Scheme four: based on this, scheme or scheme two is preferred, and the aperture of described apopore is 1mm-3mm.The aperture of apopore is not easily excessive, and when also not rotating to avoid polishing rod, namely lapping liquid spills from apopore.
Scheme five: based on this, scheme or scheme two is preferred, and described motor is servomotor.Relative to common electric machine, servomotor can controller rotating speed accurately, and controllability is strong.Meanwhile, servomotor can also reverse, the rotating that servomotor drives polishing rod to replace, polishing better effects if.
