Description
Technical field
The utility model belongs to ball base dressing technique, especially a kind of Ceramic Balls blank trimming device.
Background technology
The advanced ceramics such as silicon nitride have that density is little, hardness is high, rigidity is high, wear-resistant, thermal coefficient of expansion is low, heat endurance and the chemical stability very excellent combination property such as good, are considered to manufacture at present at a high speed, the optimal material of high-precision bearing rolling element.Ceramic Balls slightly grinds the allowance that operation will complete Ceramic Balls blank 95%, is one of bottleneck affecting ceramic ball processing efficiency always.Main cause one is silicon nitride ceramic material extreme hardness (can reach HV1600MPa), the more difficult removal of material; Two is the blank ball deviation from circular froms comparatively large (reaching 300 μm nearly) just sintered, and it is large that surplus is removed in processing.
Ceramic Balls is one of structural ceramics part be most widely used, and in its processing technology, the finishing processing of Ceramic Balls blank occupies extremely important status, and the quality of blank dressing quality is directly connected to follow-up working (machining) efficiency.At home, traditional Ceramic Balls blank finishing also rests on manual basis, its process uses Tubular tool to rotate with certain rotating speed, to remove allowance, ball base realizes the feeding of globally all directions under the operation of staff, finally process more satisfactory spheroid, but the method working (machining) efficiency is low, quality is difficult to ensure especially.University Of Tianjin appoints into ancestral etc. and proposes a kind of double abrasive wheel correction method, the relative conventional method of the method improves dressing quality to Ceramic Balls blank and efficiency, but the method still can only at every turn to single ball base processing, therefore efficiency is not high yet, and because two emery wheels carry out extruding grinding to Ceramic Balls, the Ceramic Balls blank of fragility material is easy to squeezed broken.Zhejiang Polytechnical University Ye Cheng etc. proposes the swing method for trimming of a kind of Ceramic Balls blank, the method is repaired by lower wall rotary motion and the upper dish active drive Ceramic Balls blank that swings, although the method can ensure that ball base has good sphericity, but because the linear velocity of Ceramic Balls blank circumferentially different in retainer is different, thus cause diameter consistency poor.In order to solve the low problem of grinding efficiency, now developed one " nearly end form " Ceramic Balls blank forming sintering process abroad, its deviation from circular from and variation in diameter amount all less, directly can carry out attrition process, but this technology difficulty is large, and cost is high, is difficult to large-scale promotion application.For domestic and international, the present situation that working (machining) efficiency is lower, processing uniformity is poor, cost is higher is repaired, in the urgent need to developing the Ceramic Balls blank trimming device of a kind of high efficiency, high uniformity, low cost batch machining to Ceramic Balls blank.
Summary of the invention
In order to overcome, Ceramic Balls blank finishing working (machining) efficiency is lower, processing uniformity is poor, deficiency that cost is higher, and the utility model provides that a kind of working (machining) efficiency is high, processing uniformity is good and lower-cost Ceramic Balls blank trimming device.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Ceramic Balls blank trimming device, comprise platen, retainer and pressing disc, described upper platen is positioned at above pressing disc, described retainer is between upper platen and pressing disc, the top of described upper platen is provided with the charger for providing pressurizing load, the axial line of described retainer and the rotating shaft of pressing disc are arranged in coaxial, described retainer is sleeved in the rotating shaft of described pressing disc rotationally, the rotating shaft of described upper platen and the rotating shaft of pressing disc exist determines offset distance, described offset distance is greater than the radius of platen or any dish of pressing disc and is less than the radius sum of platen and pressing disc.
Further, described retainer is in the form of annular discs, the card of described retainer has the circular working groove placed for part to be processed.
Further, described circular working groove radially, concentric circles or lattice-shaped distribution.Diameter according to Ceramic Balls blank to be processed can select suitable retainer.
The bottom surface circumference of described upper platen is provided with circular arc chamfering.
Further again, described retainer center is a sleeve, and described sleeve is placed in pressing disc rotating shaft.Certainly, also other structures can be adopted.
Technical conceive of the present utility model is: Ceramic Balls blank workpiece to be processed is placed in the retainer between upper and lower platen with certain arrangement mode, and upper and lower platen and retainer form parallel plane.Under the effect of processing load, the ball base workpiece of machining area contacts with upper and lower platen; After upper and lower platen drives and opens, ball base workpiece drives retainer to rotate under the frictional force effect of upper and lower platen, and ball base self rolls around while the revolution of retainer center, does complex space motion.Due to upper and lower platen, there is identical rotating speed and identically to turn to, although to make in retainer the relative velocity direction of different ball base circumferentially and upper and lower platen inconsistent, but size is identical, thus make at all ball bases of machining area identical with the material removing rate of upper and lower platen contact position.In addition, complicated spatial movement done by ball base workpiece, and each point on ball base alternately contacts with upper and lower platen, thus makes ball base cylindrical obtain homogeneous material removal.This device can ensure the uniformity of work pieces process condition, makes the cylindrical of each ball base workpiece obtain evenly finishing; Meanwhile, can improve working (machining) efficiency by regulating upper and lower dish rotating speed, final realization is to the high efficiency of Ceramic Balls blank workpiece, the processing of high uniformity.
The beneficial effects of the utility model are mainly reflected in: (1) once can the multiple workpiece of batch machining, the processing conditions of each workpiece is consistent, can realize the high efficiency of Ceramic Balls blank workpiece finishing processing, increase substantially the sphericity of Ceramic Balls blank and diameter and circularity uniformity; (2) ball is separated by retainer by this kind of processing unit (plant), eliminates the collision between ball and ball, avoids unnecessary damage; (3) equipment mechanism is simple, and be easy to operation, cost is low.
