Description
Technical field
The present invention relates to wall polishing machine accessory technical field, especially relate to a kind of triangle sand of wall polishing machine.
Background technology
Wall polishing machine is a kind of instrument replacing the hand-held sand papering metope of Traditional Man or object, to reach smooth, dustless, protects the able-bodied object of workman.Usually, polishing pad is the polishing part of this wall polishing machine, is also one of core component of this wall polishing machine.Wherein, triangle sand is a very important class polishing pad.But the current most complex structure of triangle sand, causes its cost higher, and polishing inner corner trim efficiency is lower, and linearity is poor.
Summary of the invention
The object of this invention is to provide a kind of triangle sand of wall polishing machine, it has, and polishing inside corner line efficiency is high, linearity good, and structure is simple, lower-cost feature.
The technical solution adopted in the present invention is: the triangle sand of wall polishing machine, comprise the upper cover be fixed on the casing of this wall polishing machine and the triangular plate being positioned at this upper cover bottom, and this wall polishing machine has the power output shaft being connected to a motor, cover rotatable cover on described and have a housing, this housing is triangular in shape, and 3 of this housing bights are equipped with downward opening first fixing hole, simultaneously, 3 bights of this triangular plate are provided with the second opening up and corresponding between two with these 3 first fixing holes fixing hole, the axial line position of this triangular plate is provided with the holding tank of upper opening, a bearing is provided with in this holding tank, in the inner ring of this bearing, card has an eccentric block, a cover plate being fixed on this holding tank upper opening place is had to be limited in this holding tank by this bearing and this eccentric block, and, the eccentric position of this eccentric block is provided with mating holes, power output shaft and this mating holes of this wall polishing machine match, and, a swinging mounting is all inserted with in these 3 first fixing holes, the other end of this swinging mounting is inserted in corresponding second fixing hole.
3 angles of described housing are separable angle.
The present invention is advantageously: polishing inside corner line efficiency is high, linearity good, and structure is simple, and cost is lower.The triangle sand of wall polishing machine of the present invention is compared to traditional triangle sand, and the parts of employing are less, comparatively simply.Meanwhile, it realizes the swing of this triangular plate by eccentric block, has effect of polishing preferably, and inside corner line of especially can polishing efficiently, makes inside corner line linearity better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the schematic perspective view of triangle sand at application state of the wall polishing machine of embodiments of the invention;
Fig. 2 is the perspective exploded view of the triangle sand of the wall polishing machine of embodiments of the invention.
Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 and Fig. 2: the triangle sand of wall polishing machine, comprise the upper cover 10 be fixed on the casing 100 of this wall polishing machine and the triangular plate 30 being positioned at this upper cover 10 bottom, and this wall polishing machine has the power output shaft being connected to a motor.Such as, this upper cover 10 is connected on this casing 100 by parts such as at least 2 snap closes 200 grade.
Further say, on this upper cover 10, rotatable cover has a housing 20.That is, the middle part of this housing 20 is provided with the through hole for being enclosed within this upper cover 10, and the exterior contour of this upper cover 10 is rounded, and the outer rim of this upper cover 10 forms matched in clearance with this through hole then.This housing 20 is triangular in shape, and 3 of this housing 20 bights are equipped with downward opening first fixing hole 21.Certainly, the closed upper part of this first fixing hole 21.Meanwhile, 3 bights of this triangular plate 30 are provided with the second opening up and corresponding between two with these 3 the first fixing holes 21 fixing hole 31.In like manner, the bottom of this second fixing hole 31 is closed.The axial line position of this triangular plate 30 is provided with the holding tank 32 of upper opening, is provided with a bearing 40 in this holding tank 32.Preferably, the outer ring of this bearing 40 and this holding tank 32 interference or interference fits.In the inner ring of this bearing 40, card has an eccentric block 50.A cover plate 33 being fixed on this holding tank 32 upper opening place is had this bearing 40 and this eccentric block 50 to be limited in this holding tank 32.And the eccentric position of this eccentric block 50 is provided with mating holes 51.That is, because this mating holes 51 is positioned at the non-axial line position of a nahlock, namely this nahlock defines this eccentric block 50 then.Power output shaft and this mating holes 51 of this wall polishing machine match.Such as, being inserted in this mating holes 51 of lower end interference fit of this power output shaft.Obviously, the middle part of this cover plate 33 is provided with the opening passed for this power output shaft.And be all inserted with a swinging mounting 60 in these 3 the first fixing holes 21, the other end of this swinging mounting 60 is inserted in corresponding second fixing hole 31.That is, this swinging mounting 60 makes to have certain spacing between this triangular plate 30 and this housing 20.Like this, after this power output shaft rotates, drive this eccentric block 50 eccentric rotary, this triangular plate 30 carries out eccentric swing in this housing 20 then, reaches the object of polishing wall.
Further say, in order to protect working face, 3 angles of this housing 20 are separable angle.That is, 3 angles of this housing 20 can realize being separated with this housing 20.Such as, these 3 angles are fixed on this housing 20 by screw.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
