Abstract
The utility model discloses a seal and an electric conducting devices of major axes of small hole machine tools. A closed flange is arranged between the upper cover and the rotating shaft. The lower part of the closed flange fits with the rotating shaft through a closed conical surface. The upper part of the closed flange fits with the upper cover through a periphery surface and an O-shaped ring. The top part thereof is provided with regulating screws and pressure springs. A steady brace is arranged around the closed flange to fix the circular motion of the closed flange. The center of the closed flange is also provided with a through hole which is perpendicularly communicated with the through hole of the high-pressure cutting fluid. The mechanism integrates the seal and the electric conducting devices, and causes the electric conductive performance and the sealing performance to be more perfect.
Description
The utility model relates to a kind of mainshaft mechanism of lathe.
In the prior art, be suitable for the electric spark small hole machining tool of processing big aspect ratio (can reach more than 200) fine holes and superdeep holes, adopt hollow electrode, interior method mostly, solve the chip removal problem towards high-pressure cutting fluid (kerosene, deionized water etc.).How solving the hollow electrode transport pulse voltage of rotation in processing and the rotary sealing of high-pressure cutting fluid, is two big difficult points in the aperture machining tool mechanism design.Mechanism design has in the past adopted the way of dividing and rule to the solution of above-mentioned two problems: 1. as shown in Figure 1, transport pulse voltage adopts traditional carbon brush structure, and its shortcoming is that carbon brush is easy to wear, complex structure.2. as shown in Figure 2, the rotary sealing of high-pressure cutting fluid adopts a plurality of " O " type circle to seal, and weak point is that rotational resistance is big, and " O " type circle is easy to wear, needs often to change.
The purpose of this utility model is: a kind of sealing and conductive mechanism of aperture machine tool chief axis are provided, and it will be to the close mechanism of the revolution of hollow electrode transport pulse voltage and high-pressure cutting fluid and two be one, and simple in structure, processing is convenient.
The technical solution of the utility model is: a kind of sealing of aperture machine tool chief axis and conductive mechanism, comprise the loam cake that is provided with the high-pressure cutting fluid through hole, the axis body of fixedlying connected with loam cake, remain on rotating shaft in the axis body by bearing, axle sleeve, nut, hollow electrode in the rotating shaft, described high-pressure cutting fluid hole is positioned at the side of loam cake; Be provided with the driving fit flange between described loam cake and the rotating shaft, driving fit flange bottom cooperates with rotating shaft by the taper closed surface, driving fit flange top cooperates with loam cake by periphery and " O " type circle, its top is provided with adjustment screw and holddown spring, be provided with steady pin around the driving fit flange and fix its circular motion, the center of driving fit flange also is provided with through hole and communicates with the high-pressure cutting fluid through hole is vertical; Be provided with rotary seal ring between described axle sleeve and the loam cake.
The utility model has the advantages that:
1. because high-pressure cutting fluid of the present utility model, through hole by driving fit flange center enters the middle hollow electrode of rotating shaft, and rely on the taper closed surface to cooperate between driving fit flange and the rotating shaft, add that driving fit flange top is provided with adjustment screw and holddown spring, so the taper closed surface can be shouldered conduction and seal two big important tasks.
2. in the utility model, rotating shaft and driving fit flange are respectively steel part and brass spare, utilize good electrical conductivity between them, adaptation and anti-attrition, conduction and rotatory sealing can be united two into one fully.
3. because driving fit flange top is provided with adjustment screw and holddown spring,, make its electric conductivity and adaptation more become perfect even after the wearing and tearing of taper closed surface, still can regulate automatically.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a conductive structure schematic diagram of the prior art;
Fig. 2 is a driving fit structural representation of the prior art;
Fig. 3 is a structural representation of the present utility model.
Wherein: 1. high-pressure cutting fluid through hole; 2. loam cake; 3. axis body; 4. bearing; 5. axle sleeve; 6. nut; 7. rotating shaft; 8. hollow electrode; 9. driving fit flange; 10. taper closed surface; 11. adjustment screw; 12. holddown spring; 13. steady pin; " 14. O " type circle; 15. through hole; 16. rotary seal ring.
Embodiment: as shown in Figure 3, a kind of sealing of aperture machine tool chief axis and conductive mechanism comprise the loam cake 2 that is provided with high-pressure cutting fluid through hole 1, the axis body 3 of fixedlying connected with loam cake 2, remain on rotating shaft 7 in the axis body 3, the hollow electrode 8 in the rotating shaft 7 by bearing 4, axle sleeve 5, nut 6; Described high-pressure cutting fluid hole 1 is positioned at the side of loam cake 2; Be provided with driving fit flange 9 between described loam cake 2 and the rotating shaft 7, driving fit flange 9 bottoms cooperate with rotating shaft 7 by taper closed surface 10, driving fit flange 9 tops cooperate with loam cake 2 by periphery and " O " type circle 14, its top is provided with adjustment screw 11 and holddown spring 12, be provided with steady pin 13 around the driving fit flange 9 and fix its circular motion, the center of driving fit flange 9 also is provided with through hole 15 and high-pressure cutting fluid through hole 1 vertical communicating; Be provided with rotary seal ring 16 between described axle sleeve 5 and the loam cake 2.Because high-pressure cutting fluid of the present utility model, enter the hollow electrode 8 of rotating shaft 7 centres by the through hole 15 at driving fit flange 9 centers, and rely on the taper closed surface to cooperate between driving fit flange 9 and the rotating shaft 7, add that driving fit flange 9 tops are provided with adjustment screw 11 and holddown spring 12, so taper closed surface 10 can be shouldered conduction and seal two big important tasks; In the utility model, rotating shaft 7 and driving fit flange 9 are respectively steel part and brass spare, utilize good electrical conductivity between them, adaptation and anti-attrition, conduction and rotatory sealing can be united two into one fully; Because driving fit flange 9 tops are provided with adjustment screw 11 and holddown spring 12,, make its electric conductivity and adaptation more become perfect even after 10 wearing and tearing of taper closed surface, still can regulate automatically.
