Description
Technical field
The utility model relates to the main shaft water flowing high pressure swivel coupling of being with machining center.
Background technology
During the Cutter Body Processing with Machining Center part, the cutter that has is cold in not having, and the cutter that has is cold in needing, based on this, and in cutter needs when cold, need be from the main shaft water flowing.At present, the domestic high pressure swivel coupling that the water flowing of machining center main shaft also do not occur.
Summary of the invention
The purpose of this utility model provides a kind of volume two ceramic chip high pressure swivel coupling that is used for the main shaft water flowing little, easy for installation, when cold, from the main shaft water flowing, provides cooling to cutter in cutter needs.
For achieving the above object, the technical solution adopted in the utility model is: a kind of two ceramic chip high pressure swivel coupling that is used for the main shaft water flowing, it is characterized in that: comprise an overcoat, bearings by two ends in overcoat has a hollow rotating shaft, the tail end of hollow rotating shaft is fixed with potsherd, the tail end of rotating shaft seals by rotating seal ring, and the leading portion endoporus of hollow rotating shaft is provided with the syndeton with main shaft; Be connected with a sleeve in the rear end of overcoat, be supported with a shifting axle in the sleeve, shifting axle is a hollow, shifting axle is coaxial with described rotating shaft, the front end of shifting axle is fixed with potsherd, be provided with back-moving spring between shifting axle and the sleeve, leave the gap between potsherd on the shifting axle and the potsherd on the hollow rotating shaft, be provided with discharge outlet at gap location; Tail end at sleeve is connected with water supply connector.
Beneficial effect: when cold, when no water under high pressure entered, the potsherd in the rotating shaft and the potsherd on the shifting axle did not keep certain clearance under the effect of back-moving spring, less than rubbing, increase the service life during rotation in not needing.When cold, water under high pressure enters in needing, and the pressure of water overcomes the power of back-moving spring, promotes shifting axle the potsherd on it is fitted with the potsherd in the rotating shaft, produces to seal, thereby water is transported in the main shaft.If a spot of water is arranged, can discharge from discharge outlet.The utility model volume is little, and is easy for installation, and the water under high pressure that flows can be taken away the heat that friction produces, and keeps the non high temperature operation, and potsherd has high-wearing feature, thereby good sealing and higher service life are arranged.
Description of drawings
The structural representation of Fig. 1 the utility model when not having water under high pressure to enter.
Fig. 2 is the view of the utility model when having water under high pressure to enter.
The specific embodiment
A kind of two ceramic chip high pressure swivel coupling that is used for the main shaft water flowing as shown in Figure 1, bearing 2 by two ends in overcoat 1 is supported with a hollow rotating shaft 13, bearing 2 is by the wavy spring pretension, the tail end of hollow rotating shaft is fixed with potsherd 10, the tail end of hollow rotating shaft is by rotating seal ring 4 sealings, the leading portion endoporus of hollow rotating shaft is provided with the syndeton with main shaft, and the syndeton at this place is hole 12, all directions; Be connected with a sleeve 5 in the rear end of overcoat, be supported with a shifting axle 8 in the sleeve 5, shifting axle 8 is a hollow, shifting axle 8 is coaxial with hollow rotating shaft 13, the front end of shifting axle is fixed with potsherd 9, be provided with back-moving spring 6 between shifting axle and the sleeve, leave the gap between potsherd 9 on the shifting axle and the potsherd 10 on the hollow rotating shaft, be provided with discharge outlet 14 at gap location; Tail end at sleeve is connected with water supply connector 7.
The utility model is connected with all directions axle of machining center main shaft 15 by the hole, all directions 12 of hollow rotating shaft 13, not only transmits moment of torsion, can move axially simultaneously, seals by sealing ring 11 between the two.This connection and spline pair transmission are similar.
Above-mentioned bearing 2 preferably adopts shield bearing, and back-moving spring 6 preferably adopts stainless steel spring.
As shown in Figure 2, when having water under high pressure to enter, under the pressure of water under high pressure 16, shifting axle 8 moves forward, and potsherd 9 is fitted with potsherd 10, produces sealing, realizes supplying water in main shaft.
Claims (2)
