CONSTITUTION:A polishing tape 1 is conveyed in the arrow direction by reels 4, 5, a traverse member 8 is supported by a slide shaft 9 provided on a machine body 2 and is traversed across the tape 1 by an eccentric roller 14 on the shaft of a motor 11. A fitting member 17 has circulation locus motion via eccentric pins provided on a motor 23 and a bearing unit 24 by the motor 23 provided on the traverse member 8, and a work W is fitted to a work fitting member 19 guided by a guide shaft 18 and pressed downward by a spring 20 and performs combined motion. The rear face of the tape 1 is supported by a support member 6 fitted to a support shaft 7, and the work W is polished smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a parts polishing device that is applied to precision finishing of end faces of optical fibers, etc.

[Conventional technology]

Conventionally, as this type of parts polishing apparatus, there is known a polishing apparatus in which the object to be polished, so-called a workpiece, moves, but the polishing surface for polishing the workpiece is fixed.

[Problem that the invention seeks to solve]

However, these polishing devices have the disadvantage that the surface roughness and finishing accuracy of the polished surface of the workpiece are not yet satisfactory.

[Means for solving problems]

The present invention aims to eliminate these inconveniences, and its gist is to provide a transport mechanism for transporting an abrasive tape;
a support member that supports the back surface of the transfer portion of the abrasive tape; a traverse member that is reciprocally movable in a direction across the abrasive tape; a traverse mechanism that reciprocates the traverse member; A parts polishing apparatus is characterized by comprising a mounting member that holds a workpiece and a movement mechanism that moves the mounting member in a circular trajectory.

[Effect]

The abrasive tape is transferred on the support member by the transfer mechanism, and the mounting member provided on the traverse member, which is reciprocally movable in a direction across the abrasive tape by the traverse mechanism, is moved in a circular trajectory by the movement mechanism.

〔Example〕

1 to 5 show preferred embodiments of the present invention, 1
2 is an abrasive tape, 2 is a machine body, and 3 is a transfer mechanism.
and a take-up reel 5 are arranged, and a feed-out roll (not shown) is rotated by two motors, fil, so that the abrasive tape 1 can be conveyed while being stretched.

Reference numeral 6 denotes a support member, and the support member 6 is attached to a support shaft 7 provided between the sides of the fuselage 2, and its upper surface is covered with the abrasive tape 1.
It is formed into a smooth surface on which the back side of the board is placed and supported.

Reference numeral 8 denotes a traverse member, and in this case, the traverse member 8 is provided so as to be movable in a direction across the abrasive tape 1 by means of two slide shafts 9 installed horizontally between the upper portions of the body 2 .

Reference numeral 10 denotes a traverse mechanism. In this case, the traverse mechanism 10 includes a traverse motor 11 provided on the side of the fuselage 2, a bracket lugs attached to its main shaft n, and eccentrically engaged with the rotational axis of the main shaft n. A mating roller 14 is provided, and an engaging member having an engaging protrusion that engages with the engaging roller 14 is attached to the traverse member 8.

Reference numeral 17 denotes a mounting member. In this case, the mounting member 17 is provided with two upper and lower guide shafts, a workpiece mounting member 19 is provided on the upper and lower guide shafts so as to be movable up and down, and the workpiece mounting member W is supported by a compression spring. The workpiece W, in this case an optical fiber, is held at the front part of the workpiece mounting member 19 by pressing downward, and the distance between the workpiece W and the polishing tape 1 below the workpiece W is adjusted by an adjustment body 21.

n is a motion mechanism; in this case, the motion mechanism n includes a motion motor n provided on the upper surface of the traverse member 8, a bearing unit blade arranged in line with the motion motor n, and a main shaft portion of the motion motor n. A driving pulley part is provided, and a driven pulley n is provided for a rotating shaft n supported by a bearing unit π.
Pass belt 4 between each pulley 3, and each pulley 4
The same amount on the bottom surface of each pulley Akane・n with respect to the rotation axis O9,
Attachment pins 30 and 31 are vertically provided at positions O and eccentric in the same direction, and attachment pins 30 and 31 are attached to the rear part of the attachment member 17 via bearings n.

Since this embodiment has the above configuration, when the traverse +11 +i10 and the interlocking mechanism n are operated while the abrasive tape 1 is transferred by the transfer mechanism 3, the traverse member 8 is polished by the action of the engagement roller 14 and the engagement groove δ. The attachment member 17, which reciprocates in the direction across the tape 1 and is provided on the traverse member 8, moves circularly by a circular locus movement, in this case a parallel link movement, and the workpiece W reciprocates in the direction across the abrasive tape 1. The workpiece W is polished by a compound movement of the transfer of the abrasive tape 1, the traverse movement of the workpiece W itself, and the circulation trajectory movement in conjunction with the circulation trajectory, and as a result, these compound movements improve the polishing work of the workpiece W and improve efficiency. It can be done in a specific manner.

Although the above-mentioned circular locus motion is a circular motion, it can also be applied to elliptical motion or other circular locus motions.

It also applies to lapping included in polishing work.

〔Effect of the invention〕

As described above, in the present invention, a workpiece is polished by a composite interlocking of the transportation of the polishing tape, the traverse motion of the workpiece itself, and the circulation locus motion, and as a result, the polishing work of the workpiece is performed efficiently by these combined motions. be able to.

As described above, the intended purpose can be fully achieved.
