The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1～Fig. 4, a kind of cylindrical component top circle processing device grinding based on the eccentric rotation-swing type biplane of retainer, comprise top lap 2, retainer 4 and lower abrasive disk 5, described top lap 2 is positioned on lower abrasive disk 5, described retainer 4 is between top lap 2 and lower abrasive disk 5, the rotating shaft of the rotating shaft of top lap 2 and lower abrasive disk 5 is coaxial setting, the axial line of described retainer 4 and the rotating shaft of upper and lower abrasive disk exist determines offset distance, and described retainer 4 is connected with retainer driving crank 7.
Further, the axle that described retainer driving crank 7 is broken line shape, exists and determines offset distance between the axial line at the upper and lower two ends of described bent axle, and the rotating shaft 6 of described lower abrasive disk is hollow form, the middle part of lower abrasive disk 5 has through hole, and described bent axle is through rotating shaft inner chamber and the through hole of described lower abrasive disk.
Further, the centre bore of described retainer 4 is connected with retainer driving crank 4.
Further again, described retainer 4 is in the form of annular discs, has the working groove of placing for part to be processed 3 in the card of described retainer 4, is radial, concentric circles or lattice-shaped and distributes.
The axial line 8 of the rotating shaft of described upper and lower abrasive disk, described retainer centre bore place axial line 9.
As illustrated in fig. 1 and 2, retainer driving crank 7 is the axle of a broken line shape, exist and determine offset, and offset is adjustable between the axial line at axle two ends, and general offset can not be less than the axial length of cylindrical work 3.Retainer driving crank 7 one end are connected with transmission system, and its axial line is coaxial with the axial line of top lap 2 and driving shaft 1, lower abrasive disk 5 and driving shaft 6; Retainer driving crank 7 other ends are connected with the centre bore of retainer 4, sliding bearing or rolling bearing can be installed between the two; Retainer 4 is placed between top lap 2 and lower abrasive disk 5, fluting on retainer 4, and workpiece 3 to be processed is placed in the groove of retainer 4; Top lap, lower abrasive disk, retainer driving crank are distinguished drive by three motors by transmission system, and rotating speed can regulate arbitrarily, ω
1for the rotating speed of top lap, ω
2for the rotating speed of retainer, ω
3rotating speed for lower abrasive disk.
As shown in Figure 3,4, retainer comprises two parts: 10. matrix; 11. hole slots.The matrix 10 of retainer is in the form of annular discs, has a plurality of hole slots 11 on matrix 10, and hole slot 11 is through hole, is used for retraining the motion of cylindrical workpiece, becomes radial, concentric circles or lattice-shaped to distribute; The shape of hole slot 11 can be the various shapes such as rectangle, octagon or circle, and the size of hole slot 11 is enough to just put into cylindrical workpiece; The line of symmetry of hole slot 11 can point to matrix 10 center, or with matrix 10 be radially definite drift angle, generally in 15 °.
