Description

The rotary connector that is used for the suction line of surfacing device
Technical field
The present invention relates to be used to connect two sections rotary connector of the dust collecting system of surfacing device.
Background technology
As everyone knows, the instrument of running forms dust in environment, thereby causes problems.Remove these dusts with suction tool and can improve the running environment of instrument and operator's working environment.For instance, can consider not improving of in closed environment, turning round with the track polishing machine of dust suction.
Although prior art has undeniable work convenience, and the combination of dust collecting system and instrument may cause the ergonomics problem owing to having increased this burdensome thing of sweep-up pipe and having lacked flexibility when determining the position of sweep-up pipe; But in fact, connector of the prior art makes sweep-up pipe can only be disposed in a position, this position generally be in the vertical or parallel direction of dust suction face on.
An exemplary shortcomings of this layout is: reduced the operation possibility of described instrument on described sweep-up pipe direction.For example, for the track polishing machine that must in narrow environment, work, generally arrange the sweep-up pipe outlet perpendicular to working surface.Equally, by utilizing its connector that is parallel to wall, polishing machine is worked between two walls that lean on very closely.Obviously, unless the direction of described sweep-up pipe connector can change, otherwise described polishing machine can not either way can worked.
Summary of the invention
Therefore, the objective of the invention is to overcome above defective.
According to the present invention, above-mentioned purpose is to realize by the rotary connector of the dust collecting system that links to each other with machining tool.
The rotary connector that is used for the suction line of surfacing device of the present invention comprises first sleeve and second sleeve, this first sleeve and second sleeve link together along the surfaces of revolution, this surfaces of revolution tilts with respect to the axis of described two sleeves, and described two sleeves longitudinal axis separately can form at least two positions at an angle to each other.
In addition, can rotate mutually around an oblique rotating shaft according to two sleeves of connector of the present invention, described oblique rotating shaft and dust suction direction angle at 45, the edge is the normal direction of the surfaces of revolution separately.One of them sleeve is connected to suction hose, and another sleeve is connected to the side of instrument, is used to suck particle.Because the type of the connection between described two sleeves, the relative position between their axis separately can be selected in a continuous manner as required, and therefore described axis separately can overlap, perhaps each other at an angle of 90.

Fig. 9 has showed connector of the present invention, and wherein said second sleeve and described polishing machine are one;
Figure 10 is the profilograph of another embodiment of connector of the present invention.
The specific embodiment
Among the figure, connector 50 of the present invention comprises first sleeve 1 and second sleeve 2.Among Fig. 1, polishing machine 52 connects 51 by connector 50 and rotation and is connected to a pipe, and this pipe is connected to vacuum cleaner again.
Fig. 4 and Fig. 5 have described described first sleeve 1, and as can be seen from the figure, described first sleeve 1 is a hollow circular cylinder 3, and this hollow circular cylinder 3 has free end 4 and the rotatable end 5 that is used to connect vacuum cleaner.This rotatable end 5 is made of cylindrical projections 6, and the outside of this cylindrical projections 6 is with annular element 7, and the diameter of this annular element 7 is greater than the diameter of described cylindrical part 6, and the diameter of the end portion of this annular element 7 and other parts narrow.The axis of described rotatable end 5 can be directed, among the exemplary and nonrestrictive in the drawings embodiment, and the axis angle at 45 of the cylindrical part 3 of the axis of described rotatable end 5 and described first sleeve 1.Another characteristics of described cylindrical projections 6 and annular element 7 are: have the radially-arranged two pairs of grooves 8 along described cylindrical part, these two pairs of grooves 8 are divided into four parts with described cylindrical part 6 and described annular element 7, to realize two purposes, first purpose is increase described rotatable end 5 flexible, because this rotatable end 5 must be meshed with the respective recess of second sleeve, second purpose is to realize relative rotation between the described sleeve simply by overcoming locking torque, described locking torque causes that by the engagement of the complementary protuberance on the groove 8 and second sleeve this point will be explained below.
Fig. 6,7 and 8 has described second sleeve 2.As can be seen from the figure, second sleeve 2 comprises hollow circular cylinder 9, and this hollow circular cylinder 9 has and is used for the free end 10 and the rotatable end 11 that are connected with machining tool.This rotatable end 11 comprises bellmouth 12, the diameter of this bellmouth 12 inwardly dwindles, thereby make described cylindrical projections 6 and described annular element 7 can be pushed into wherein and be assembled together, has at least one pair of projection 13 on the described bellmouth 12, this projection 13 can reduce described diameter a little, thereby reduces the opening size of described bellmouth 12.The described projection 13 of described second sleeve is meshed with the corresponding recesses 8 of described first sleeve, making can be by touching the relative rotation that realizes between the described sleeve, thereby the machine that connector of the present invention for example ought be installed in the running, prevents the freedom of described connector, not controlled rotation.Another basic characteristics of described rotatable end 11 are that the axis of this rotatable end can be directed, in the exemplary and nonrestrictive in the drawings example, and the axis angle at 45 of the hollow circular cylinder 9 of described axis and described first sleeve 1.
In when assembling, in the bellmouth 12 that the described cylindrical part 6 and the annular element 7 of described first sleeve 1 pushed described second sleeve 2, note described projection 13 and described groove 8 are matched.At this moment, described rotatable end 5 and two axis of 11 will overlap, and constituting single rotating shaft 14, and described first sleeve 1 and second sleeve 2 will link together along the surfaces of revolution 53, the described surfaces of revolution 53 with respect to the axis of described two sleeves for tilting, and perpendicular with described rotating shaft 14.Described projection 13 preferably is distributed on the radial axle, shown in Fig. 6 and 8; Described groove 8 is distributed on two radial axles that are perpendicular to one another, and as shown in Figure 4, thereby according to purpose of the present invention, two operating positions, promptly parallel with vertical with sleeve axis position forms locking temporarily.
If desired, can use suitable locking member in described first sleeve 1 and second sleeve 2, provide 0 ° with 90 ° outside other operating position.
In addition, in another embodiment, described sleeve 2 is an one with described instrument 52.
Figure 10 has showed another embodiment of connector of the present invention, wherein, first sleeve 1 and second sleeve 2 have hollow circular cylinder 3 and 9 separately, this hollow circular cylinder 3 and 9 has identical free end 4 and 10, rotatably accommodates the identical or different lining of diameter 21 and 22 in this free end 4 and 10.Thereby described connector 50 can be rotationally attached to vacuum cleaner and machining tool.
