Background technology:

At present, existing disk through type taper roller spheric end grinding machine, its emery wheel is a solid cylinder, emery wheel axis and feed table axis normal are arranged, the emery wheel operative end surface is trimmed to concave spherical surface, emery wheel is around self axis rotation, and workpiece is worn into shape from the abrasive wheel end face center by quilt under the drive of feed table.Because the linear velocity of abrasive wheel end face each point is directly proportional with radius, linear velocity is the highest in outer radius, is zero at circle centre position, causes the cutting power of emery wheel core very low.When workpiece process emery wheel core, because of the too low normally grinding of grinding speed, heating is serious, has influenced crudy.Simultaneously,, be difficult for keeping the stability of spherical shape because emery wheel core wearing and tearing are slower, trimming wheel continually, thereby shortened service life of emery wheel, also influenced production efficiency.

The utility model content:

In order to overcome existing disk through type taper roller spheric end grinding machine because of the adverse effect that the emery wheel center line velocity is low excessively, the cutting power difference causes crudy, the utility model provides a kind of novel tapered roller spheric end grinding machine, can improve the crudy of lathe, reduce the finishing number of times of emery wheel, enhance productivity.

The utility model is to adopt following technical scheme to realize:

Described novel tapered roller spheric end grinding machine, two disks and the separator of this grinding machine are positioned at same axis, two disks are contained in Y-axis one end respectively, Y-axis is connected with separately reductor by belt pulley, belt, belt pulley respectively, separator is contained on the mandrel, and mandrel is packed in the right axle axle sleeve; Cylinder grinding wheel is contained in an end of grinding wheel spindle, and grinding wheel spindle is connected with motor by belt pulley, belt, belt pulley; The axle sleeve of grinding wheel spindle is fixed on the slide that links to each other with the feeding handgrip, the axle of feeding handgrip is connected with compensated motor by gear, particularly: upright position deflection one angle beta of the center line of the center line of the cylinder grinding wheel of this device and two disks, and intersect at the center line of the home position of separator and disk.

Described novel tapered roller spheric end grinding machine, the cylinder grinding wheel of this grinding machine (5) are the emery wheel of tubular rather than solid cylinder emery wheel.

Adopt the technical scheme that the utility model proposed, can obtain following beneficial effect:

First, with the upright position deflection certain angle of emery wheel axis from the feed table axis, grinding workpiece is not passed through from the core of emery wheel, solved the low excessively problem of emery wheel core grinding linear velocity, help improving grinding efficiency, reduced the tendency that surface of the work is burnt simultaneously.The second, adopted cylinder grinding wheel.Because after the emery wheel deflection, core is not participated in grinding, removes the emery wheel core and has both saved emery wheel material, has significantly reduced the finishing number of times of emery wheel again.The cylinder grinding wheel working face is an annular sphere, and average cutting ability is improved.The 3rd, adopted disk through type feeding style.The feeding style of this existing spheric end grinding machine is through facts have proved not only efficient height, and the manufacturing of frock is comparatively convenient.
