Abstract
It the utility model is related to accurate grinding technology field, a kind of specifically eccentric rotary workpiece polishing mechanism, contiguous block is provided between motor and eccentric rotary mechanism, eccentric rotary mechanism includes eccentric shaft, internal gear, external gear and bearing, eccentric shaft is arranged on the main shaft of motor, is arranged on after outer gear sleeve upper bearing (metal) on eccentric shaft, and grinding head is arranged on external gear, internal gear is arranged on contiguous block, external gear and internal gear intermeshing.Compared with the existing technology, combining structure simple possible, cost is cheap, reliable and stable, the advantage is that for the utility model：By the setting of eccentric rotary mechanism, increase polishing area, and using gear make grinding head when high-speed rotation still can stable operation, effect of polishing will not be influenceed because of the increase of bite.
Description
[technical field]
Accurate grinding technology field is the utility model is related to, specifically a kind of eccentric rotary workpiece polishing mechanism.
[background technology]
Mobile phone productses are very high to appearance requirement, and its product surface would generally produce shake knife mark and bright after CNC is processed
Spend far from enough, it is impossible to meet the requirement of product quality, it is therefore desirable to remove knife mark and polish beat it is bright.Will in practical operation
For the curved surface asked and be bordered without any interference, split is perfect, and none point of art designing line destroys, and this that to be prior art be difficult to is perfect real
Existing.Many of industrial production sander, such as China's number of patent application：CN201320633388.X discloses one kind and is used for machine
The eccentric rotary sander of tool sanding and polishing, but its grinding wheel diameter is still larger, the polishing for being not particularly suited for handset shell is thrown
Light.Therefore, in view of the above-mentioned problems, to realize, reliably polishing grinding, and reduce input cost stable to mobile phone productses, design
Develop this eccentric rotary workpiece polishing mechanism.
[utility model content]
The purpose of this utility model is solve the deficiencies in the prior art, there is provided a kind of eccentric rotary workpiece polishing mechanism, utilizes
The advantages of gear make grinding head when high-speed rotation still can stable operation, will not be influenceed because of the increase of bite
Polishing effect so that sanding and polishing performance is more stable, reliably.
To achieve these goals, a kind of eccentric rotary workpiece polishing mechanism, including motor, grinding head and eccentric rotary machine are designed
Structure, it is characterised in that be provided with contiguous block between motor and eccentric rotary mechanism, eccentric rotary mechanism include eccentric shaft, internal gear,
External gear and bearing, eccentric shaft are arranged on the main shaft of motor, are arranged on after outer gear sleeve upper bearing (metal) on eccentric shaft, grinding head peace
On external gear, internal gear is arranged on contiguous block, external gear and internal gear intermeshing.
Shell tool among described grinding head and external gear.Described motor driven eccentric shaft motion, grinding head due to
Rotary motion is made in the effect of eccentric shaft and the cooperation of internal-external gear.
Compared with the existing technology, combining structure simple possible, cost is cheap, reliable and stable for the utility model, and its advantage exists
In：By the setting of eccentric rotary mechanism, polishing area is increased, and make grinding head when high-speed rotation using gear
Still can stable operation, will not be influenceed because of the increase of bite polish effect.

In figure：1. the pad 8. of 6. bearing of motor 2. contiguous block, 3. eccentric shaft, 4. internal gear, 5. external gear 7. is polished
Head.
[embodiment]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this device people professional to this
For be very clear.It should be appreciated that specific embodiment described herein is only to explain the utility model, and do not have to
In restriction the utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of described eccentric rotary workpiece polishing mechanism, including motor (1), grinding head (8) and partially
Heart rotating mechanism, it is characterised in that contiguous block (2) is provided between motor (1) and eccentric rotary mechanism, eccentric rotary mechanism includes
Eccentric shaft (3), internal gear (4), external gear (5) and bearing (6), eccentric shaft (3) are arranged on the main shaft of motor (1), external gear
(5) it is arranged on after covering upper bearing (metal) on eccentric shaft (3), grinding head (8) is arranged on external gear (5), and internal gear (4) is arranged on connection
On block (2), external gear (5) and internal gear (4) intermeshing.Shell tool among described grinding head (8) and external gear (5)
(7).Described motor (1) drives eccentric shaft (3) motion, and grinding head (8) is due to the effect of eccentric shaft (3) and matching somebody with somebody for internal-external gear
Cooperate rotary motion.
Embodiment
GWS7-100ET speed governing high torques sander is chosen according to the characteristics of the utility model, during specific implementation as revolution
Power source, then eccentric rotary mechanism of the present utility model is set, form with it is unique be driven, be dust-proof, cooling circuit, possessing can
The internal-external gear of the eccentric rotary workpiece polishing mechanism of the power source leaned on, contiguous block and engagement make it that grinding head is stable, actual
Polishing excellent, can realize the perfect split between handset shell curved surface.
