Description
Technical Field
The utility model relates to a cylindrical grinder emery wheel is dust keeper for (holding) chuck.
Background
The cylindrical grinding machine is a grinding machine for processing the outer surface and the shaft shoulder end surface of a cylindrical, conical or other-shaped plain line of a workpiece, and is widely used. The grinding wheel chuck is an important component structure of the cylindrical grinding machine.
In the prior art, a grinding wheel chuck of an external cylindrical grinding machine is generally of an open structure at the front section of a grinding wheel spindle, and ground metal dust and grinding wheel ash are easy to permeate into the spindle and a framework oil seal, so that the external circular surface of the spindle and the contact surface of the spindle and the oil seal are abraded, the precision of the grinding wheel spindle is reduced, oil leakage of a grinding wheel box body is caused and the service life is influenced after long-term use.
SUMMERY OF THE UTILITY MODEL
The utility model provides a cylindrical grinder emery wheel is dust keeper for (holding) chuck, its purpose aims at overcoming the above-mentioned not enough that prior art exists, stops metal dust and emery wheel ash infiltration emery wheel spindle and skeleton oil blanket, increase of service life.
The technical solution of the utility model is as follows: cylindrical grinder emery wheel (holding) chuck is with dust keeper, its structure includes the emery wheel (holding) chuck, (holding) chuck apron and emery wheel main shaft, wherein emery wheel spindle nose portion projects to the case lid outside, the inboard and emery wheel spindle nose junction of case lid is the skeleton oil blanket, the emery wheel (holding) chuck is established to the cover on the emery wheel spindle nose portion in the case lid outside, the inboard annular arch of ring is established near case lid department to the emery wheel (holding) chuck, the step of circle circumference is established to case lid outside edge cooperation arch, emery wheel (holding) chuck edge is the emery wheel, the (holding) chuck apron is established in the emery wheel outside, emery wheel (holding) chuck and (holding) chuck.
The utility model has the advantages that: the structure is simple and effective, the grinding wheel chuck is close to the end part of the grinding wheel spindle, a dustproof mechanism (protrusion) is added on the grinding wheel chuck based on the prior art, the infiltration of metal dust and grinding wheel ash can be avoided, the precision of the grinding wheel spindle is ensured, the oil leakage of the grinding wheel box body is prevented, and the service life of the grinding wheel box body is prolonged.
