Description
Technical Field
The utility model belongs to the grinding machine spare part especially relates to a be used for multiple seal structure work piece axle water installations of grinding machine.
Background
In the bearing working face grinding process, the cooling water pipe is used for spraying water mist to cool, the cooling effect is guaranteed, and the burning of the bearing working face is avoided. The cooling water pipe sprays water to the processing surface, and water is discharged through the workpiece shaft water inlet device, so that the cooling effect in the grinding processing process is ensured. Because the frequency of use of intaking of current work piece axle is high, and work piece axle afterbody water installations is heavy to sealed bearing among the water installations is because structural factor, and long-time large tracts of land contacts with water, and it is not very good to lean on sealed bearing structure to seal the effect, intakes easily, causes whole water installations life to scrap less. Therefore, the grinding machine multi-sealing structure workpiece shaft water inlet device which is effectively adaptive to severe environment, prevents the workpiece shaft water inlet device from being damaged and has quick replacement and repair remedial measures is very necessary to develop.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not good problem of work piece axle water installations water-proof effects among the prior art, provide one kind and adapt to adverse circumstances, effectively prevent into water damage and the prosthetic multiple seal structure work piece axle water installations of quick replacement.
The utility model provides a technical scheme that its technical problem adopted: a workpiece shaft water inlet device with a multiple sealing structure comprises a workpiece shaft, a water inlet pipe, an oil slinger, a sealing bearing and a quick plug, wherein the water inlet pipe is a non-standard pipe, an L-shaped bump I is arranged on the outer ring of the water inlet pipe, an inverted L-shaped bump II is arranged on the inner ring of the oil slinger, the water inlet pipe is sleeved in the oil slinger, a cavity for accommodating the sealing bearing is formed between the oil slinger and the water inlet pipe, the sealing bearing is sleeved on the water inlet pipe, the outer ring of the sealing bearing is fixedly connected with the inner ring of the oil slinger, a Z-shaped deep cavity is formed between the bump I and the bump II on one side of the, the workpiece shaft is a hollow shaft, one end of the workpiece shaft is provided with a cylindrical groove, an oil slinger is arranged in the cylindrical groove, an outer ring of the oil slinger is fixed on an inner ring of the workpiece shaft, one end of the water inlet pipe extends into the inner cavity of the workpiece shaft, the other end of the water inlet pipe fixes the quick plug, and the water inlet pipe and the workpiece shaft form an L-shaped deep cavity.
The utility model discloses using-way and principle: when the water inlet device is used, the water inlet device is only required to be inserted into one end of the workpiece shaft and is fixed with the workpiece shaft through the oil slinger of the water inlet device. Because water installations one side has set up lug I and lug II, the baffle that lug I and lug II formed can prevent effectively that water from contacting sealed bearing, when work piece axle work is rotatory, the water of infiltration "Z" type deep cavity can be thrown out, further prevents water contact sealed bearing, and water installations opposite side is equipped with sealing washer and closing cap.
The utility model has the advantages that: the utility model discloses a multiple seal antiseep technique application has effectively avoided water to get into the bearing, prolongs work piece axle water installations's life greatly to design light in weight is indestructible, and it is convenient that the installation is changed.
