Abstract
The utility model discloses a kind of dustless sanders, it is characterized by: main includes polishing machine host, grinding wheel is installed on the transmission shaft of polishing machine host, there is dust-proof cover on the outside of grinding wheel, dust-proof cover includes soft dust preventing component, fixed dust cover and rotation dust cover, it is provided with dust suction interface on fixed dust cover, and has opening on fixed dust cover, fixed dust cover connects soft dust preventing component with rotation dust cover lower end.The utility model can be realized the dustless polishing of sanding to the curved surfaces and inner corner trim such as plane and most metallic conduits, reduce the dust that field polish generates, and reduce field personnel's health risk.
Description
Technical field
The utility model relates to a kind of dustless grinding device, the sanding for the planes such as metallic conduit or curved surface is handled.
Background technique
Currently, carrying out polishing sanding processing work to pipeline-weld in the non-destructive testing of petroleum industry oil and gas transportation pipeline
Work amount is big and can generate a large amount of dust, even if staff wears anti-dust mask and is also difficult to avoid that dust to operator's health
It seriously affects, needs a kind of dustless sanding equipment.What the sanding processing now for the planes such as metallic conduit or curved surface was polished
There are mainly two types of modes, one is manual polishing, this mode low efficiency, heavy workload；Another kind be by means of sander into
Row polishing, mechanical grinding can generate a large amount of dust, seriously affect the health of operator.It is needed to form dustless effect
Seal closure is installed to sander, such as Publication No. CN201702625U, publication date is that China disclosed on January 12nd, 2011 is special
Sharp technical solution, sander mainly includes the polishing emery disc and seal closure that power device drives, but this sander is only applicable to
The dustless polishing of plane, when polishing the curved surfaces such as metallic conduit, seal closure and buffed surface cannot completely attach to form sealed environment,
It will cause dust leakage, dustless effect can not be formed.For another example Publication No. CN202640153U, publication date are on January 2nd, 2013
Disclosed technical solution, this sander mainly include polishing emery disc, seal closure and the elastic skirt that power device drives, can be right
Certain curved surface carries out dustless polishing, but has a certain distance between the outer rim of seal closure and round emery disc outer rim, encounters pipeline
At the inner corner trim for intersecting weld seam, circular seal closure makes round emery disc that can not be polished to corner close to the position of inside corner line, meeting
Leave dead angle.
Summary of the invention
The utility model is intended to provide a kind of dustless sander for defect and deficiency present in the above-mentioned prior art,
The utility model can be realized the dustless polishing of sanding to the curved surfaces and inner corner trim such as plane and most metallic conduits, reduce field polish
The dust of generation reduces field personnel's health risk.
The utility model is realized by using following technical proposals:
A kind of dustless sander, it is characterised in that: main includes polishing machine host, is installed on the transmission shaft for machine host of polishing
There is grinding wheel, there is dust-proof cover on the outside of grinding wheel, dust-proof cover includes that soft dust preventing component, fixed dust cover and rotation are dust-proof
Cover is fixed on dust cover and is provided with dust suction interface, and has opening on fixed dust cover, fixed dust cover and rotation dust cover lower end
Connect soft dust preventing component.
The dust-proof cover opening of fixation is 105o, and there are two locating slots on fixed dust cover, is fixed to rotate dust cover；
There is dust suction interface on fixed dust cover, is connect with sweep-up pipe；There is located hand wheel on the rotation dust cover, rotary cover is facilitated to rotate
It is mobile, and matched with the locating slot on fixed dust cover, reach locating effect.
There is band between the rotation dust cover and fixed dust cover, so that rotation dust cover is rotated to the dust-proof phase of fixation
When answering position, reach sealing effect.
The fixed dust cover can be rotated around fixing axle, and it is dust-proof to adjust fixation at any time during inner corner trim polishing
The position of cover opening.
The fixed dust cover and rotation dust cover are fabricated to by plastic transparent material.
The fixed dust cover and the dust-proof shroud rim of rotation install soft dust preventing component, are made of several circle hairbrush, in oblique
Outer openings shape plays sealing function when with work face contact.
Rotation dust cover can be rotated to fixed dust cover and be opened in common polishing by dustless sander described in the utility model
At mouthful, disc dust cover is formed, guarantees the dust-proof effect in bruting process.It polishes to plane or curved surface inner corner trim
When, dust cover rotated away can will be rotated, round emery disc outer rim is just tangent with notch at this time, fixed dust-proof cover opening and inner corner trim
Face coincide, and to the no dead angle of the polishing of inner corner trim and can guarantee dustfree environment.
Compared with prior art, the utility model is achieved has the beneficial effect that:
1, the dustless sanding processing that the utility model can be used to plane can also carry out at dustless sanding certain curved surface
Reason.
2, the inner corner trim polishing to metallic conduit infall weld seam, strong applicability can be thus achieved in the utility model.

Specific embodiment
As the preferred forms of the utility model, it to be a kind of available that it discloses a kind of general dustless grinding devices
In the dustless polishing to plane or curved surface, the utility model is further illustrated below with reference to diagram.
Grinding wheel 8 is installed in a kind of rotary shaft of dustless sander host, there is fixed 11 He of dust cover on the outside of grinding wheel 8
Rotate dust cover 5.When dustless sander polishes to plane or curved surface, twisted by the connection buckle 10 on dustless sander
Rotation dust cover 5 is closed by located hand wheel 6, and rotation dust cover 5 is fixed at locating slot 1, passes through fixed dust cover
The deformation of soft dust preventing component 15 and the soft dust preventing component 16 of rotation dust cover makes dust-proof cover 1 cover entire working face, and
And rotation dust cover 5 and fixed dust cover 11 are sealed by band 1, band 27, band 3 14.Start vacuum cleaner
3, dust will enter sweep-up pipe 2 from dust suction interface 12, and the negative pressure formed in dust cover stops dust leakage.Encountering plane
Or curved surface inner corner trim part when, can will rotation dust cover 5 open, will rotation dust cover 5 be fixed at locating slot 2 13, grinding wheel
8 part of piece leaks out, and then polishes inner corner trim, and the opening shape of fixed dust-proof cover 11 is the tangent line of circle where grinding wheel 8
The stroke for promoting dust is arch, the negative pressure that cooperation vacuum cleaner is formed in dust cover when polishing, the part of leakage be equivalent into
Port, air flow into inside outside dust cover, and air-flow is formed under suitable vacuum cleaner power, and there is some strength will hinder
Only dust leaks outside.
