Detailed description of the invention
Present embodiment discloses a kind of polishing guard shield, and it can be set in and be polished workpiece and polishing working head is peripheral, when working head polishing of polishing is polished workpiece, can by with the coordinating of liquids and gases, play the effect of cooling dedusting.At this, being polished workpiece is crucible, and polishing working head be emery wheel is that object lesson is described, and certainly, it will be appreciated by persons skilled in the art that being polished workpiece can also need buffing work-piece for other, and working head of polishing also can be other grinding tool.
Now, please refer to Fig. 1, Fig. 1 is the side-looking structural representation of the polishing guard shield 100 of broken section, and this polishing guard shield 100 comprises cover body 110, and this cover body 110 comprises inwall 111 and outer wall 112, a cavity 113 is formed between inwall 111 and outer wall 112, whole cover body 110 is a hollow structure, and inwall 111 forms the container cavity 115 that has opening 114, and this opening 114 is positioned at the bottom of cover body 110, crucible can enter this container cavity 115 through this opening 114, and emery wheel is arranged in container cavity 115.Emery wheel can be rotated by drive unit, and in the present embodiment, drive unit comprises motor and rotating shaft, and motor drives emery wheel to rotate by rotating shaft, thus emery wheel can be polished to crucible.
Outer wall 112 is offered liquid hand-hole 121 and gas injection hole 122 respectively, in cavity 113, injects liquid and Compressed Gas by liquid hand-hole 121 and gas injection hole 122.Generally, liquid is pure water, and Compressed Gas is compressed air; Certainly this liquid also can be other cooling fluid, and Compressed Gas is the gas after other pressurizations.Inwall 111 is offered first and portal 123, the liquid in cavity 113 can portal from first and 123 flow to container cavity 115 after the pressurization of Compressed Gas.Liquid after pressurization can not easily be thrown away by the centrifugal action of emery wheel that rotates, effectively can give emery wheel and crucible cooling, and be easier to touch dust, liquid and mix dust, thus easier further process is done to dust, compared with prior art, this polishing guard shield 100 promotes the effect of cooling dedusting without the need to the power by improving water pump, and fluid volume significantly reduces.
In the present embodiment, first portals on 123 can install rotatable water pipe 151, the flow direction of regulates liquid is carried out by regulating rotatable water pipe 151, particular location according to crucible and emery wheel regulates rotation water pipe 151, make most of liquid can flow to emery wheel and crucible, optimize the effect of cooling dedusting.
Please refer to Fig. 1 and Fig. 2, this polishing guard shield 100 is substantially in cylindric, and namely the shape in its cross section is circular.Certainly, this polishing guard shield 100 also can be round table-like, prism-shaped etc., it will be appreciated by persons skilled in the art that the shape of this polishing guard shield 100 can be arranged according to actual conditions such as the shape such as emery wheel, crucible, sizes.
In the present embodiment, also fan is provided with in container cavity 113, this fan includes some flabellums 131, after this starting fan, flabellum 131 rotates, after the rotating speed of flabellum 131 reaches given pace, certain negative pressure is formed in container cavity 113, crucible is polished the dust got off and can raises up, and can prevent dust from escaping like this, thus pollutes external environment condition.
Preferably, flabellum 131 can be driven by drive unit and rotate, flabellum is connected with installing sleeve, installing sleeve can be fixed in rotating shaft, motor driving axis of rotation, and rotating shaft drives installing sleeve to rotate, thus drive flabellum 131 to rotate, thus flabellum 131 and emery wheel synchronous rotary, drive flabellum 131 to rotate without the need to other external force, economize energy.In the present embodiment, shaft hole 161 can be offered above cover body 110, this shaft hole 161 runs through inwall 111 and outer wall 112, and motor is arranged on the outside of cover body 110, and rotating shaft is connected with the flabellum 131 and emery wheel being positioned at container cavity 115 through this shaft hole 161.
In the present embodiment, inwall 111 also offers second and portal 124, second portals on 124 is provided with atomising device 152, also can to portal 124 outflows from second at the liquid in cavity 113 after pressurization, and flow to container cavity 115 after atomising device 152 is atomized, the liquid after atomization can be attached on dust, the dust be thus attached on liquid is subject to Action of Gravity Field and sedimentation downwards, also the operating on centrifugal force not being vulnerable to emery wheel is thrown on inwall 111, makes inwall 111 not easy to clean.Dust after decline also can be easier follow-up process is carried out to it, significantly promote the effect of dedusting.In the present embodiment, this atomising device 152 comprises atomization grid, and atomization grid is set directly at second and portals on 124, as long as the grid gap of atomization grid is enough little, just liquid can be atomized.In the present embodiment, first portal 123 be arranged on below, and second portal 124 be arranged on top, namely the first distance of plane residing for 123 to opening 114 of portalling is less than second and portals 124 to the distance of plane residing for opening 114, make non-atomized liquid and atomized liquid can have the rational flow direction like this, optimize cooling dust removing effects.The liquid of these atomizations can also rinse flabellum 131, makes flabellum 131 not easily speckle with mud, makes it not easily produce fault.
In the present embodiment, cover body 110 also offers steam vent 141 and air admission hole 142, steam vent 141 and air admission hole 142 all run through inwall 111 and outer wall 112, steam vent 141 is opened in the top of cover body 110, air admission hole 142 is arranged on the bottom of cover body 110, be connected with pipeline 210 between steam vent 141 and air admission hole 142, pipeline 210 is in outer wall 112 side with the link of steam vent 141 and air admission hole 142, and pipeline 210 is communicated with container cavity 115.Due to the effect of fan, dust moves up, the liquid of atomization can be attached on these dust, the dust of the liquid attachment that part is not atomized continues to move up, and overflows, and continue to enter container cavity 115 from air admission hole 142 by pipeline 210 from steam vent 141, these dust continue to move up, until the liquid of attachment atomization, sedimentation downwards, significantly can promote dust removing effects so under gravity.
In the present embodiment, polishing guard shield 100 also comprises seal 171, the seal 171 is arranged on opening 114 edge, the seal 171 is arranged along opening 114 edge in the below of cover body 110, the seal 171 can be made for wear-resisting soft material, as polytetrafluoroethylene (PTFE), rubber etc., in bruting process, the seal 171 can coordinate with cover body 110 and crucible and makes opening 114 be in approximate closed state, thus can by liquid storage in container cavity 115, the dust declined also can be deposited in these liquid, these liquid and dust are not easy to escape, facilitate follow-up process.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
