Abstract
The utility model discloses a plunge grinding machine for external sphere, which comprises a servo motor driving a work-piece carriage and a dresser for dressing. A cup grinding wheel is mounted at a mandrel of a grinding head seat, and the front end of the positioning mandrel is in the shape of conical surface which is engaged with an elastic expansion sleeve capable of expanding. The grinding head seat is fixed on a grinding head carriage. A slew cylinder drives a positioning mandrel, and the cup grinding wheel is made of rubber bonding agent. The plunge grinding machine for external sphere has the advantages that the cup grinding wheel is used to grind work-pieces, as the principle of generating grinding is utilized and the cup grinding wheel is made of rubber bonding agent, sand grains can fall off naturally without dressing during grinding, and when the cup grinding wheel is used to grind the external sphere, the plunge grinding machine can make up the shortage of low surface finish resulting from defect of sand grains at a certain position, because the whole circle of the grinding wheel is engaged in grinding the external sphere.
Description
Technical field:
The utility model relates to a kind of horizontal grinding spherical outside surface grinding machine, is specially adapted to the inner ring spherical outside surface of grinding oscillating bearing and angular contact articulated bearing.
Background technology:
Common grinding is to carry out on numerical control bearing inner race grinding machine, adopt toroidal wheel, crushing is gone out consistent by grinding wheel arc dresser with the bearing spherical shape, the relation of deviation from spherical form and trimmer is very big, because the radius of gyration error of trimmer, the emery wheel of repairing out also has error, therefore deviation from spherical form is bigger, moreover the bearing grinder employing is electric magnetic no-core clamp, electric magnetic no-core clamp is by the magnetic force that the solenoid energising produces workpiece to be adsorbed on the magnetic pole, makes workpiece centre of gyration rotation around self under the effect of workpiece spindle and support.
Summary of the invention:
Task of the present utility model is to propose a kind of cup emery wheel and sphere to contact time error little, and the grinding spherical outside surface is to highly polished a kind of horizontal grinding spherical outside surface grinding machine.Task of the present utility model is finished like this, a kind of horizontal grinding spherical outside surface grinding machine, it comprises that servomotor drives the reparation of workpiece planker and trimmer diamond pen, it is characterized in that: cup emery wheel is contained on the mandrel of bistrique seat, the positioning core axle front end is the conical surface, but the conical surface cooperates with the elastic expansion-sleeve of a tensioner.The bistrique seat is fixed on the bistrique planker.Angling cylinder drives positioning core axle, and cup emery wheel adopts gum cement to make.The utlity model has following effect: come grinding work piece with cup emery wheel, owing to adopt model to become the principle of mill, the material of cup emery wheel adopts gum cement, need not repair during grinding, sand grains promptly can come off naturally, when cup emery wheel grinding spherical outside surface, because the whole annulus of emery wheel all participates in the grinding spherical outside surface, it can remedy the low phenomenon of surface smoothness that certain sand grains defective causes.
Description of drawings:
Fig. 1 is the structural representation on lathe plane, and Fig. 2 is the grinding area partial enlarged drawing.
Drawing explanation: 1, lathe bed, 2, the workpiece planker, 3, workpiece box, 4, trimmer, 5, angling cylinder, 6, servomotor (a), 7, the bistrique planker, 8, servomotor (b), 9, the bistrique seat, 10, inner ring spherical outside surface workpiece, 11, positioning core axle, 12, cup emery wheel, 13, elastic expansion-sleeve.
The specific embodiment:
Parts on the lathe all are fixed on the lathe bed 1, and workpiece planker 2 is driven by servomotor 6 (a) and seesaws, and control the finishing of the front and back position and the trimmer gold pen of workpiece thus.Cup emery wheel 12 is contained on the mandrel of bistrique seat 9, bistrique seat 9 is fixed on the bistrique planker 7, positioning core axle 11 front ends are the conical surface, but the conical surface cooperates with the elastic expansion-sleeve 13 of a tensioner, servomotor 8 (b) drives bistrique planker 7 and seesaws, thereby the cup emery wheel that also drives on the bistrique seat seesaws, and inner ring spherical outside surface workpiece 10 is clamped by elastic expansion-sleeve, and angling cylinder 5 drives the positioning core axles motion, when positioning core axle moves backward, utilize the conical surface with the elastic expansion-sleeve spreading, thus the elastic expansion-sleeve spreading with the workpiece tensioner, the bistrique planker is fed to grinding position grinding work piece, the workpiece grinding finishes, the bistrique planker retreats, and the tensioner mandrel unclamps, and manually takes off workpiece.
Claims (3)
