Description
Technical field
The present invention relates to polishing field, a kind of bistrique driving structure is particularly related to and with the bistrique driving structure
Rubbing head.
Background technology
With the development of science and technology, have benefited from the prosperity of the communication technology, including the intelligent artifact such as smart mobile phone, panel computer is
As the life regular supplies of modern, especially smart mobile phone, almost everyone is owned by, and it can converse, surfs the Net, takes pictures, regard
Frequency etc., functional diversities.In the prior art, built-in product of protection interior of mobile phone and to form the mobile phone shell of cell phone appearance be typically logical
Cross injection and manufacture, but but rough surface and bending resistance are poor for the mobile phone shell being molded with plastic product, therefore in order to improve
Aesthetic feeling and sense of touch and to mobile phone shell perform coating or painting process.Lightening is the trend of current smart mobile phone development, tradition modeling
The thickness of material or glass casing continues to be thinned will be unable to meet hand set machine shell hardness and intensity requirement at present close to the limit, and
Traditional casing thickness then can be reduced to 0.6mm by metal chassis in the case where meeting intensity and changing firmness requirements by 1.1mm,
About 0.5mm is thinned.In addition, the texture and aesthetic feeling of metal and good thermal diffusivity have also promoted the release of metal chassis.Tradition
Metal hand casing performed by operating personnel by manual working when making the surface grinding of the mobile phone shell be processed as light
Sliding grinding steps, i.e. polishing step.However, the mobile phone shell polishing of this manual working by operating personnel depends on operation
The qualification of personnel and careful notice, therefore, it is difficult to maintain homogeneous quality, especially curved surface polishing, quality discrepancy is more
Greatly, the time and needed for polishing is longer, therefore has the problem of being unsuitable for a large amount of productions.Mobile phone shell polishing i.e. of the prior art
Process is difficult to maintain homogeneous quality under conditions of unskilled operating personnel, and the time needed for polishing operation also compared with
It is long, therefore productivity ratio reduction.
Polissoir then is had, drives bistrique rotation to polish by motor, however, because bistrique direct-assembling is in electricity
On machine output shaft, motor is closer to the distance with bistrique, in reality processing, easily occurs motor entering water, enters dirt situation, influences motor
Service life, or even there is situations such as motor is burnt out.Meanwhile, existing polissoir is mostly that motor drives single bistrique work
Make, it is necessary to change head, it is necessary to shut down when polishing different accuracy, operation is inconvenient, and influence production.
