In precise sphere mass production process, the V-shaped groove polishing is a kind of method in common that adopts at present.The characteristics of this method are to adopt the abrasive disk that has V-shaped groove, with the Precision Machining of free abrasive realization spheroid, are a kind of two lapping modes that abrasive disk is coaxial up and down.The subject matter that exists is: the spin angle θ of (1) spheroid is a fixed value, and grinding track is inhomogeneous, and balling-up is poor; (2) working (machining) efficiency is low, and efficient is lower when particularly processing the high-hardness ceramic ball.In actual production, often, can receive certain effect, but this raising is limited by increasing the uniformity that artificial stirring improves grinding track.In recent years, at the improvement of V-shaped groove polishing research some achievements are arranged also, more representational have: centering type V-shaped groove polishing, coaxial three coils polishings.The starting point of these methods is exactly by changing the position relation and the motion control of abrasive disk up and down, improve the uniformity of grinding track, thereby it is reach the purpose of the balling-up that improves the V-shaped groove polishing, but increased the complexity of structure and control, and not ideal aspect the raising of efficient.For grinding technics, adopt fixed abrasive material more much higher than the efficient that adopts free abrasive to grind, but because the difficulty of precision, finishing and the precision maintenance aspect of moulding, the abrasive disk that has V-shaped groove is difficult to make the fixed abrasive material abrasive disk.
Summary of the invention
The purpose of this utility model is exactly the deficiency that balling-up is poor, efficient is low, mechanism is complicated that will overcome above-mentioned processing method, and the simple and easy processing unit (plant) of the employing flat tool processing spheroid that a kind of grinding precision is good, efficient is high, simple in structure is provided.
Planetary type precise sphere grinder described in the utility model, comprise the plane fixed abrasive material abrasive disk of doing gyration, this abrasive disk connects main motion transmission mechanism, the main motion drive motors in the body, described abrasive disk top is eccentric to be provided with one and to make the retainer of gyration around the central shaft of himself, described retainer auxiliary connection motion work, described secondary motion transmission mechanism be arranged on body on column on crossbeam on, and be connected with the secondary motion drive motors; Be installed with the position retaining hole of holding the ball base on the retainer, there is last platen on the top on the ball base, and last platen is provided with pressing spring, and ball base bottom contacts with described abrasive disk; Described major and minor motion work is equipped with speed regulator.
Retainer is arranged on the support of position adjustable.Crossbeam 7 links to each other with body by column 4, and column 4 terminal employings are threaded, and can adjust the distance between crossbeam and abrasive disk easily.
Abrasive disk adopts the fixed abrasive material abrasive disk, and by motor-driven, adjustable-speed mainly realizes the removal of material; Retainer places the abrasive disk top and leaves certain space with abrasive disk, does gyration by motor-driven, and rotating speed is adjustable; Grinding pressure is provided by last platen, and big I is regulated by spring; The ball base under the thrust of the frictional force of the abrasive disk that is rotated, platen pressure and retainer, constantly when the retainer axis of rotation is made revolution motion, is made spinning motion continuously in retainer, thereby realizes the efficient removal uniformly of material; Abrasive disk can be by finishing ring online finishing to guarantee its precision.
Compare with traditional sphere grinder, the utlity model has following advantage:
(1) result of motion analysis shows, the spin angle θ of spheroid changes in process of lapping continuously, and can control by the speed of adjusting retainer and abrasive disk, grinds good uniformity, can realize complete balling-up campaign, guarantee the grinding precision of spheroid.
(2) because abrasive disk is flat, convenient formation, be easy to finishing, therefore can make the fixed abrasive material abrasive disk, during the processing ceramic ball, can select diamond abrasive for use, can select the CBN abrasive material for use during the processing steel ball, the use of the application of super hard abrasive and fixed abrasive material abrasive disk can improve ball lapping efficient greatly.
(3) can realize the online finishing of abrasive disk, the precision that helps abrasive disk keeps.
(4) this kind Ginding process is separated ball by retainer, eliminates the collision of ball and ball, has avoided unnecessary damage, and is particularly important for the processing of Ceramic Balls.
(5) simple in structure, easy to operate.
In a word, planetary type precise sphere grinder provided by the utility model can improve grinding precision and the grinding efficiency that accurate ball is produced in batches, and is more obvious to Ceramic Balls attrition process advantage.
