    Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.
    1 is a partial longitudinal sectional view of a polishing apparatus to which a coupling device for a glass polishing apparatus according to the present invention is applied. As described with reference to FIG. 7, the upper clutch member 5 is provided at the lower end of the wear table 3 installed on the turntable 1 of the glass polishing machine and supporting the glass 4 in rotation. A lower clutch member 7 is disposed below the upper clutch member 5, and a driving shaft 9 is installed to the lower clutch member 7 so as to be lifted and rotated. One side of the drive shaft 9 is provided with a reducer 13 and a drive motor 11 for rotating the drive shaft 9, and a drive for lifting and lowering of the drive shaft 9 below the drive shaft 9. The cylinder 15 is provided. A coupling device 21 according to the present invention is interposed between the drive shaft 9 and the drive cylinder 15.
    Coupling device 21 according to the present invention, the upper flange member 23 is coupled to the lower end of the drive shaft (9) and capable of lifting up and down integrally to the cylinder rod (17) of the drive cylinder (15). A lower support member 25 coupled to the lower flange member 25, a rotation support member 27 interposed between the upper flange member 23 and the lower flange member 25 to be integrally rotatable to the lower end of the drive shaft 9; And a plurality of bearing members 29 interposed between the rotation support member 27 and the lower flange member 25 to rotatably support the rotation support member 27.
    2 is an enlarged view of the coupling device of FIG. 1, FIG. 3 is a plan view of the upper flange member of FIG. 2, FIG. 4 is a plan view of the lower flange member of FIG. 2, and FIG. 5 is a view of the rotation support member of FIG. 2. 6 is a plan view of the bearing support member of FIG. 2. As shown in these figures, the upper flange member 23 has a cylindrical shape, a plurality of bolt holes 31 for bolting with the lower flange member 25 in the circumferential direction is formed through the outer peripheral edge. .
    The through hole 32 is formed in the central region of the upper flange member 23 so that the drive shaft 9 can pass therethrough, and the upper side of the through hole 32 extends along the radial direction from the through hole 32. A seating portion 33 recessed from the upper surface is formed. The mounting portion 33 supports the drive shaft 9 so as to be rotatable, and a sealing member 35 for sealing is mounted thereon. A receiving portion 34 extending along the radial direction and recessed upward from the lower surface is formed below the through hole 32.
    The lower flange member 25 has a cylindrical shape so as to be in contact with the upper flange member 23, and the outer peripheral portion has a bolt fastening hole 37 corresponding to the bolt hole 31 formed in the upper flange member 23, respectively. Formed. In the central region of the lower flange member 25 is formed a receiving portion 38 recessed from the upper surface to accommodate the rotation support member 27 in cooperation with the upper flange member 23, the receiving portion 38 In the central region of the bottom of the bottom surface, a coupling hole 39 having a female threaded portion is formed to be coupled to the cylinder rod 17 of the driving cylinder 15. An oil supply hole 40 is formed at a side of the lower flange member 25 so as to communicate with the receiving portion 38 so that oil from the outside can be supplied into the receiving portion.
    On the other hand, the rotation support member 27 is compared with the inner diameter of the receiving portion (34, 38) to be transversely axially in the receiving portion (34, 38) of the upper flange member 23 and the lower flange member 25. It has a reduced outer diameter. The upper surface of the rotation support member 27 is formed with a depression 43 recessed to accommodate the lower end of the drive shaft (9). A screw through hole 44 is formed in the central area of the bottom of the depression 43 so as to be fastened to the drive shaft 9 with the screw 48, and the side circumferential surface is rotatable integrally with the drive shaft 9. The fixing bolt hole 45 is formed to face each other so that the fixing bolt 46 to be fixed can be coupled.
    Under the rotation support member 27, a bearing support member 47 having a disc shape and penetrating through the plate surface and having a plurality of bearing accommodation holes 47 is arranged, and within each bearing accommodation hole 48, a rotation support member. The bearing member 29 is accommodated in the 27 and the lower flange member 25 so as to be in rolling contact with each other.
    By such a configuration, when the glass product 4 to be processed is loaded on the wear table 3 provided on one side of the turntable 1, the turntable 1 causes the glass product 4 to be placed under the polishing tool (not shown). It will rotate 180 degrees to be placed. Then, the polishing tool rotates while descending, and at the same time, the driving cylinder 15 operates in the extending direction to engage the lower clutch member 7 with the upper clutch member 5. At this time, the drive motor 11 is rotated and the rotational force of the drive motor 11 is to rotate the drive shaft 9 through the reducer (13).
    On the other hand, when the drive shaft 9 is inclined with respect to the axis of the drive cylinder 15 or a deviation occurs due to wear or vibration of a part supporting the drive shaft 9, the drive shaft 9 is inclined. The load or deviation is suitably compensated by the flow of the rotation support member 27 coupled to the lower end of the drive shaft 9. As a result, the inclination of the cylinder rod 17 is prevented from the drive cylinder 15, so that uneven wear of the drive cylinder 15 due to the inclination or deviation of the drive shaft 9, oil leakage, etc. are suppressed.
    As described above, according to the present invention, interfering between the shaft and the driving cylinder for driving the shaft along the axial direction, compensating for the displacement of the shaft and the axis of the driving cylinder, thereby suppressing the forced deterioration due to uneven wear of the driving cylinder. A coupling device for a glass polishing machine is provided.
