Abstract
The invention discloses a water leakage preventing structure for a hydraulic chuck of a spindle of a numerical control vertical lathe, which comprises the spindle, wherein the hydraulic chuck is installed at the end of the spindle through a connection disk, a pull rod is arranged in an inner hole of the spindle, an annular groove is processed on one side of the connection disk close to the chuck, an inclined discharging hole is processed on the connection disk, an inner end port of the discharging hole is communicated with the annular groove, and an outer end port of the discharging hole is located on the outer side of the connection disk and lower than the inner end port. A sealing ring is arranged between an inner hole of the connection disk and the pull rod. During operation of the lathe, when the middle portion of the hydraulic chuck has leaked liquid, the leaked liquid enters the annular groove, and due to the fact that the inclined discharging hole on the connection disk is communicated with the annular groove, the leaked liquid can be automatically discharged through the discharging hole and is recovered into a circulation system through a cooling liquid recovery part of the lathe. The sealing ring is arranged between the pull rod and the spindle so that downward flowing of the leaked liquid is effectively avoided and the leaked liquid is prevented from flowing to the ground.
Description
Technical field
The present invention relates to a kind of anti-water-leaking structure of main shaft of lathe, particularly a kind of numerical control vertical lathe main axle hydraulic pressure chuck is prevented water-leaking structure.
Background technology
The main shaft of NC vertical lathe and be installed in oild chuck on the main shaft and be perpendicular to that horizontal plane is provided with; Cooling water, the cooling fluid of oild chuck top often leak out between main shaft and the pull bar from the chuck hub position in the running; The leakage meeting is taken advantage of a situation downwards, flows out to ground from the below of lathe.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, leakage and do not get into the anti-water-leaking structure of the numerical control vertical lathe main axle hydraulic pressure chuck that between main shaft and the pull bar, can not leak out to ground, overcome the deficiency of prior art.
Numerical control vertical lathe main axle hydraulic pressure chuck of the present invention is prevented water-leaking structure; Comprise main shaft, the termination of main shaft is equipped with oild chuck through terminal pad, is provided with pull bar at the main shaft endoporus; On terminal pad, be processed with annular groove near chuck one side; On terminal pad, be processed with the tap of inclination, the tap inner port is communicated with described annular groove, and the external port of tap is positioned at the outside of terminal pad and is lower than inner port; Between the endoporus of terminal pad and pull bar, be provided with sealing ring.
Numerical control vertical lathe main axle hydraulic pressure chuck of the present invention is prevented water-leaking structure; When leakage appearred in the oild chuck middle part, the leakage meeting got in the annular groove, owing to have the tap of inclination to be communicated with annular groove on the terminal pad; Leakage can be discharged and reclaimed by the cooling fluid recovery part of lathe and got into the circulatory system from tap; Between pull bar and main shaft, sealing ring is arranged, effectively stoped leakage dirty, prevented that leakage from flowing to ground.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 2 is main shaft; The upper end of main shaft 2 is equipped with oild chuck 7 through terminal pad 5; Be provided with pull bar 1 at main shaft 2 endoporus, on terminal pad 5, be processed with annular groove 6, on terminal pad 5, be processed with the tap 4 of inclination near chuck 7 one sides; Tap 4 inner port are communicated with annular groove 6, and the external port of tap 4 is positioned at the outside of terminal pad 5 and is lower than inner port; Between the endoporus of terminal pad 5 and pull bar 1, be provided with sealing ring 3.
In the lathe running; When leakage appearred in oild chuck 7 middle parts, the leakage meeting got in the annular groove 6, owing to have the tap 4 of inclination to be communicated with annular groove on the terminal pad 5; Leakage can be discharged and reclaimed by the cooling fluid recovery part of lathe and got into the circulatory system from tap 4; Between pull bar 1 and main shaft 2, sealing ring 3 is arranged, effectively stoped leakage dirty, prevented that leakage from flowing to ground.
