Abstract
The utility model discloses a plastic cellphone shell surface sanding device which comprises a polishing motor packaged in a shell. An output shaft of the polishing motor is arranged at one end outside the shell and provided with a concentric sleeve shaft which is provided with an elastic ring, and a polishing layer is wrapped outside the elastic ring. A sponge ring is arranged on the basis of the concentric shaft, and sand paper is sleeved outside the sponge ring, so that a polishing head with an elastic soft face contacts with the plastic cellphone shell when polishing, the effect of finger imitation is achieved, jumping and bumping are avoided when polishing, and closely clinging to the plastic shell is realized to meet various irregular curved faces according to elasticity, so that the effect of attractiveness in processing is realized; and labor strength can be relieved for polishing, and safety of fingers can be protected.
Description
Technical field
The utility model relates to a kind of sanding apparatus of plastic cellphone casing, especially a kind of device for sandpapering.
Background technology
Along with individual trend, fashion, the lifting of aesthetic standard, people have also reached best to the appearance requirement of mobile phone products, comparatively speaking so that the manufacturing technology of phone housing also is rich in challenge, part is arranged in injection moulding and the special materials radium carver stealthy signal antenna mobile phone shell of forming strip of planting, because produced a kind of imperceptible technique step between stealthy letter sky line and the plastic cellphone shell, need manual grinding smooth or smoothly be tangential on cambered surface, technique for grinding requires high, labor strength is very big, and even the workman is polished to and has pointed the bleeding blister phenomenon; Certainly also have now and use the polishing motor and polish, directly with the sand paper snare on rigid polishing concentric shafts, when this mode is polished plastic casing, owing to be hard to hard contact, immediately to the plastic casing polishing of jolting of beating, make product directly scrap so at a touch.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of and can use machine polishing and directly do not hurt the workman and point the plastic cellphone shell surface sanding device that can produce imitative finger effect simultaneously.
For achieving the above object, the utility model has adopted following technical proposals:
This plastic cellphone shell surface sanding device, include the polishing motor that is encapsulated in the housing, the end outside housing is provided with the output shaft of polishing motor, is provided with concentric sleeve at described output shaft, be provided with elastic ring at concentric sleeve, be provided with the polishing layer in the elastic ring outsourcing.
Described elastic ring is sponge ring.
Described polishing layer is sand paper.
The external diameter of described sponge ring is greater than the internal diameter of polishing layer sand paper.
Pass through technique scheme, because the basis at concentric axle sleeve is provided with a sponge ring, outside sponge ring, put again sand paper, tactile with grinding head and the plastic cellphone shell joint of soft of elasticity in polishing, played the effect of imitative finger, do not jolt thereby can not beat during polishing, cater to various irregular curved surfaces but be close to plastic shell elasticity, reach processing technology effect attractive in appearance; Simultaneously can alleviate the labour intensity of polishing work, and the protection finger safe.
Description of drawings
Fig. 1 is the schematic perspective view of this utility model plastic cellphone shell surface sanding device.
Fig. 2 is the solid assembling schematic diagram of this utility model plastic cellphone shell surface sanding device.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is made further description.
As shown in Figure 1 and Figure 2, this plastic cellphone shell surface sanding device, include the polishing motor that is encapsulated in the housing 1, end outside housing is provided with the output shaft 2 of polishing motor, be provided with concentric sleeve 3 at described output shaft, be provided with elastic ring 4 at concentric sleeve, be provided with polishing layer 5 in the elastic ring outsourcing; Specifically, described elastic ring is sponge ring, and described polishing layer is sand paper, and simultaneously, the external diameter of described sponge ring is greater than the internal diameter of polishing layer sand paper.
When installing, at first sponge ring is placed in the sand paper layer inner circle, sponge ring has softness and is imbued with in flexible characteristics, the internal diameter than sand paper is slightly large again for its external diameter simultaneously, thereby the sand paper circle firmly can be locked, and then the concentric sleeve of grinding head is inserted the sponge ring inner circle, be installed in after entangling firm equally on the output shaft of polishing motor, open the polishing motor power, adjust the rotating speed of suitable feel, just can process the mobile phone plastic shell.After the sand paper circle that rotates contacted plastic cellphone shell surface gently, the curved surface that the grinding head that rotates is not advised along mobile phone shell moved, to reach the polishing effect.
Compared with prior art, owing to be provided with a sponge ring on the basis of concentric shafts, outside sponge ring, put again sand paper, tactile with grinding head and the plastic cellphone shell joint of soft of elasticity in polishing, played the effect of imitative finger, do not jolt thereby can not beat during polishing, cater to various irregular curved surfaces but be close to plastic shell elasticity, reach processing technology effect attractive in appearance; Simultaneously can alleviate the labour intensity of polishing work, and the protection finger safe.
