DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for polishing an outer surface of a work having opposing parallel surfaces along an axial direction.

[0002]

2. Description of the Related Art The applicant of the present invention has previously proposed an apparatus for polishing a workpiece having an opposing parallel surface as shown in FIGS. The above device mounts a work having an opposing parallel surface on a base so as to be able to slide and rotate in the axial direction, and arranges endless abrasives on both sides of the work to provide an endless abrasive on any surface of the work. The abrasive is pressed into contact.

Next, the operation will be described. The work W is gripped by the chuck member 113, and the vertical plate 117 is slid to the right as shown in FIG. 4 so that one rough polishing member 100 is pressed against the outer flat surface of the work W and the other finish polishing material 111 is moved to the work W The work W is reciprocated and polished in the axial direction. After completion of one surface of the work W, the other polishing plane is rotated to the polishing position by the rotation member 115 to polish the plane. After the rough polishing, the vertical plate 117 is slid to the left in FIG. 4 to remove the rough polishing member 100 from the work W, and the right finish polishing member 111 is pressed against the work W to perform the same finish polishing as described above.

[0004]

In the prior art described above, it is difficult to rotate the workpiece so that the plane to be polished is positioned parallel to the surface of the polishing member. There was a problem that it was not possible to polish the surface uniformly.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide endless abrasives on both sides of a work having opposing parallel surfaces to provide play in the rotation direction of the support portion of the work. A pressing member for pressing the endless abrasive on the opposed parallel surface from the outside is provided, and the work is mounted on a base so as to be able to reciprocate and intermittently rotate in the vertical direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the embodiments shown in FIGS. Figure 1,
FIG. 2 shows a first embodiment of the present invention. A chuck member 3 and a tail head 4 that support both ends of the work W are mounted on a slide table 2 slidably disposed on a base 1, and the chuck member 3 is rotated by a rotating member 5. It can be moved and has some backlash in the rotation direction. Reference numeral 6 denotes a known slide device that slides the slide table 2 back and forth. A vertical plate 7 is disposed on the base 1 so as to straddle the work W in a right angle direction.
11 are suspended on guide plates 12, 13, 14, 15 and 16, 17, 18, 19, respectively. The plates 12, 16 are intermittently driven by intermittent rotating members 20, 21 so as to be fed by a fixed amount. Cylinders 22 and 23 are disposed on both sides of the work W, and rods 24 and 2 are provided.
5 a pressing member 2 for pressing the opposing parallel surface of the workpiece W
6 and 27 are attached, and are constantly pressed against the work W by the springs 28 and 29.

Next, the operation will be described. The work W having the opposing parallel surface is gripped by the chuck member 3 and the cylinders 22 and 23 are operated to press the pressing members 26 and 27 against the opposing parallel surface of the work W. Since the work W has some backlash in the rotation direction, the work W is held between the pressing members 26 and 27, and the polishing members 10 and 11 are pressed against the opposing parallel surfaces of the work W without any gap. In this state, the slide device 6 is operated to reciprocate the work W to perform polishing. After the polishing is completed, the work W is rotated by the rotating member 5. At this time, the pressing member 2
When the corners of the workpiece W press and retract the workpieces 6 and 27 and the other polished surfaces face the pressing members 26 and 27, the spring 2
At steps 8 and 29, the pressing members 26 and 27 are pressed against the new polishing surface. In the first embodiment, when the workpiece is rotated, the corner of the workpiece may come into contact with the pressing member and be damaged.

FIG. 3 shows a second embodiment in which such disadvantages are eliminated. Denoted at 30 and 31 are cylinders. Pressing members 34 and 35 are fixed to the tips of the rods 32 and 33. When polishing the work, the cylinders 30 and 31 are operated to advance the pressing members 34 and 35, and the polishing members 10 and 11 are moved. The workpiece W is pressed against the polishing surface. After polishing, cylinder 3
The workpiece W is rotated backward by the operation member 0, 31 and is rotated by the rotation member 5 of the work W so that the new polishing surface is opposed to the pressing members 34 and 35. Then, the cylinders 30 and 31 are operated to move forward to polish as described above. I do.

[0009]

According to the present invention, endless abrasives are provided on both sides of a work having an opposing parallel surface to give backlash in the direction of rotation of the support portion of the work, and the endless abrasive is pressed against the opposing parallel surface from the outside. Since the pressing member is disposed on the base so that the work can be reciprocated and intermittently rotated in the vertical direction, the opposing surface of the work having the opposing parallel surface to be polished can be easily and reliably. It can be pressed against the polishing member and can polish the polishing surface uniformly.
