Description
Technical field
The utility model relates to a kind of dust sealing device, the especially dust guard of robot turn-screw.
Background technique
At present, widely used leading screw in robot generally all needs an external connecting plate that slide block and other external movement devices are linked together on slide block.Leading screw is in the continuous firing process, and the dust in the operate outside environment, smog and some other small solid particles can have a strong impact on the running precision and the working life of leading screw.Continue to-and-fro motion because external connecting plate will drive external movement mechanism, will realize that therefore the sealing and dustproof of leading screw just compares difficulty.The known useful dustproof screw set of leading screw dust-tight mode directly is enclosed within leading screw outside and realizes dustproofly, also have and utilize soft rubber thin slice or sheet iron etc. that leading screw peripheral working space is carried out environmental sealing, but above-mentioned sealing effect is all undesirable.Especially high heat, the high radiation of some particular job occasions generations can be the leading screw dirt-proof boot of rubber or roastingization of soft rubber thin slice; And the non-telescoping property of sheet iron certainly will increase the overall dimensions of robot, thereby has increased the weight of robot, has also influenced the overall appearance of robot simultaneously greatly, and these shortcomings will make the usability of robot reduce greatly.
Therefore, in order to overcome the deficiency that existing leading screw seal arrangement sealing effect is undesirable, overall appearance is lacked and influenced to seal durability, need a kind of leading screw seal arrangement of development, the sealing device can not only effectively be realized the dustproof isolating seal of leading screw, and the compact structure of Sealing, the working life of prolongation leading screw that can also be bigger in abominable working environment such as high temperature, high radiation.
Summary of the invention
According to background technique, the purpose of this utility model is to provide a kind of leading screw dust-tight seal arrangement, one section arc surface is processed in the upper surface middle part zone that is about to the I-shaped connecting plate of motion slide block connection, an elongated band steel is pressed in the arc surface upper end, and band steel two ends are fixed on the two ends of whole sealing device; All the other non-motion join domain thin aluminum sheet shutoff, two ends all use screw fastening.Drive in the reciprocating process of external agency at I-shaped connecting plate, the ridge that is pressed in the band steel of I-shaped connecting plate circular arc upper surface is made corresponding change along with the motion of slide block.Because the remaining part of whole sealing device surface except that the band steel all is completely fixed sealing, and the tiny protuberance of the band steel that circular arc causes is because the transitional function of arc surface and connection cover plate and the pressuring action of band keeper plate of steel to the band steel, also the leading screw to inside has played good sealing, thereby makes whole device reach the purpose of leading screw dust sealing.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of leading screw dust guard, mainly constitute by fixed seal casinghousing (1) and the aperture slots assembly (2) that is tightly connected, wherein: the leading screw (26) that is screwed with feed screw nut (25) is connected with base plate (12) with coupling seat (14) by leading screw supporting base (27), is connected with motion slide block (24) on feed screw nut (25); Side plate (11) and base plate (12), and thin aluminum sheet (15) and side plate (11), the end of end portion supports (13) and coupling seat (14) are connected and interconnect common composition and have the move fixed seal casinghousing (1) of slit A of certain-length; By I-shaped connecting plate (23), external member connecting plate (28), band steel (21) and band steel fixed plate (22) the composition aperture slots assembly (2) that is tightly connected, wherein I-shaped connecting plate (23) top is set on thin aluminum sheet (15) outer surface by motion slit A, the top braces arc surface (29) of I-shaped connecting plate (23), on I-shaped connecting plate (23) top, be connected with external member connecting plate (28), its lower end and motion slide block (24) interconnect, band steel (21) passes the hole of arc surface (29) composition of external member connecting plate (28) and I-shaped connecting plate (23), and be pressed on the arc surface (29), be fixed by band steel fixed plate (22) and end portion supports (13) and coupling (14), constituted sealing, formed the leading screw dust guard jointly by fixed seal casinghousing (1) and the aperture slots assembly (2) that is tightly connected to the motion path aperture slots.
Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, the position of the tump that causes owing to arc surface of band steel of the present utility model is along with the motion of I-shaped connecting plate changes, but arc surface is for transitional function and the band keeper plate of steel and the restriction that is connected cover plate of sealing surfaces, make whole dust guard when guaranteeing mechanism's effective exercise, obtained good dust-proof and isolated purpose.
2, the utility model is simple in structure, compact, and be easy to structure maintenance and repairing the working life of leading screw in the abominable working environment such as prolongation high temperature that can be bigger, high radiation.
