Come, the development with technology and innovation, the demand expanding day to stainless steel pipe for the people, the requirement to its quality is not yet
Disconnected raising.Roughness due to reducing stainless steel pipe inwall can reduce the suction in inwall of the resistance of inwall convection cell and material
Attached effect, so, the requirement more and more higher to stainless steel pipe inner wall roughness for the people.
So, it is badly in need of a kind of good pipe fitting inner wall sanding apparatus of polishing effect.
Utility model content
The purpose of this utility model is to provide a kind of hollow pipe fitting sanding apparatus, overcomes hollow pipe fitting inwall to be difficult to polish
Shortcoming.
For reaching above-mentioned purpose, basic technology scheme of the present utility model is to provide a kind of hollow pipe fitting sanding apparatus, bag
Include workpiece polishing mechanism and inflation mechanism, workpiece polishing mechanism include polishing set, polishing set from outside to inside be divided into tool resilient wearing layer and
Pressure cavity；It is provided with shaggy projection outside wearing layer；Inflation mechanism includes inflated hose and air pump, the entering of inflated hose
Gas end is connected with air pump, and the outlet side of inflated hose is connected with pressure cavity, and inflated hose is wrapped with metal support tube.
During using such scheme, workpiece polishing mechanism includes polishing set, and polishing set is divided into wearing layer, pressure cavity from outside to inside,
Wearing layer is provided with shaggy projection, and the projection on the wearing layer of polishing set outer layer, for this device and pipe fitting inner wall
The position of contact, raised rough surface makes coefficient of friction big, when projection produces friction with pipe fitting inner wall, can be in pipe fitting
Wall is polished, and great friction coefficient can be conducive to strengthening the effect of polishing.It is cavity in pressure cavity, pressure cavity sets
There is air inlet, air inlet inflation is made to lead to pressure expandable cavity after gassy in cavity, and then make to be located at outer layer
Wearing layer extruded by pressure cavity and also begin to expand, and contact with pipe fitting inner wall rapidly；Gas in pressure cavity
After pressure reaches certain degree, wearing layer becomes hard because being extruded, and easily facilitates and pipe fitting inner wall is polished.Air inlet
On be connected with inflated hose, inflated hose is wrapped with metal support tube, and the input of inflated hose is connected with air pump, and air pump is
The source of the gas of this device, inflated hose is the passage of gas transmission, and metal support tube is used for consolidating inflated hose and air exercise grinding set
There is provided and support.
The preferred version 1 that the improvement of base case is obtained, wearing layer is made up of polyurethane material, and polyurethane has well
Wearability, service life can be increased.
The preferred version 2 that the improvement of base case is obtained, pressure cavity is provided with sealing with the junction of inflated hose
Ring, sealing ring can prevent gas from leaking.
Brief description
Fig. 1 is the structural representation of this utility model hollow pipe fitting sanding apparatus embodiment.
Specific embodiment
Below by specific embodiment and reference, this utility model is described in further detail：
Reference in Figure of description includes：Hollow pipe fitting 1, projection 2, wearing layer 3, pressure cavity 4, inflated hose
5th, metal support tube 6, air pump 7.
Embodiment is substantially as shown in Figure 1：A kind of hollow pipe fitting sanding apparatus, including workpiece polishing mechanism and inflation mechanism, beat
Grinding machine structure includes polishing set, and polishing set is divided into the resilient wearing layer 3 of tool and pressure cavity 4 from outside to inside；Set outside wearing layer 3
Have shaggy raised 2；Inflation mechanism includes inflated hose 5 and air pump 7, and the inlet end of inflated hose 5 is connected with air pump 7,
The outlet side of inflated hose 5 is connected with pressure cavity 4, and inflated hose 5 is wrapped with metal support tube 6.
Workpiece polishing mechanism includes polishing set, and polishing set is divided into wearing layer 3, pressure cavity 4 from outside to inside, and wearing layer 3 is provided with
Shaggy raised 2, the projection 2 on the wearing layer 3 of polishing set outer layer, the portion contacting with pipe fitting inner wall for this device
Position, raised 2 rough surface makes coefficient of friction big, when raised 2 produce friction with pipe fitting inner wall, pipe fitting inner wall can be carried out
Polishing, and great friction coefficient can be conducive to strengthening the effect of polishing.Wearing layer 3 is made up of polyurethane material, and polyurethane has
Good wearability, can increase service life.It is cavity in pressure cavity 4, pressure cavity 4 is provided with air inlet, to air inlet
Mouth inflation can lead to pressure cavity 4 to expand after making gassy in cavity, and then makes the wearing layer 3 being located at outer layer pressure
Cavity 4 extrudes and liquid starts to expand, and contacts with pipe fitting inner wall rapidly；When the air pressure in pressure cavity 4 reach certain
After degree, wearing layer 3 becomes hard because being extruded, and easily facilitates and pipe fitting inner wall is polished.The expansion system of pressure cavity 4
Number is more than described wearing layer 3 coefficient of expansion；Pressure cavity 4 is more sensitive to the pressure of gas；Make the expansion journey of pressure cavity 4
Degree is bigger, it will wearing layer 3 is extruded；So that be difficult to produce during pressure cavity 4 work loosening impact polishing effect.Enter
Inflated hose 5 is connected with QI KOU, inflated hose 5 is wrapped with metal support tube 6, the input of inflated hose 5 is connected with gas
Pump 7, air pump 7 is the source of the gas of this device, and inflated hose 5 is the passage of gas transmission, and metal support tube 6 is used for consolidating inflated hose
5 and air exercise grinding set provide support.Pressure cavity 4 is provided with sealing ring with the junction of inflated hose 5, and sealing ring can prevent
Gas leaks.
Mode of operation：First the polishing set of unaerated is inserted in pipe fitting to be polished, then booster air pump 7 air exercise grinding set is filled
Gas, when gas reaches suitable pressure, projection on wearing layer 32 and pipe fitting inner wall be fully contacted and wearing layer 3 now
Through possessing considerable degree of hardness, now necessarily move metal support tube 6 and polishing set can be driven to move together, Er Qie
Pipe fitting inner wall can be rubbed while mobile, it is achieved thereby that the polishing to hollow pipe fitting 1.
Sanding apparatus are inflated by the filling effect by gas for this device, thus realizing the realization of fitting with tube wall
The function of Friction Sanding.
