Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for automatically applying an abrasive to the peripheral surface of a buff in a buffing machine.

[0002]

[Prior art]

 Heretofore, as this type of abrasive coating device, there have been known, for example, Japanese Utility Model Publication No. 52-153991, Japanese Utility Model Publication 60-21169 and Japanese Utility Model Publication No. 63-17651. Each of these abrasive coating devices employs a mechanism in which the abrasive is slidably accommodated in a cylinder, which is an abrasive accommodating cylinder, and the abrasive is delivered by the action of pressurized air. Therefore, the shape of the abrasive is limited to a substantially cylindrical shape, and when the abrasive is applied to the buff, the abrasive is not fixed integrally with the container.

[0003]

[Problems to be solved by the device]

 According to the method described in the prior art, the amount of the abrasive applied can be controlled by adjusting the air pressure, but it has been difficult to apply a small amount of the abrasive or finely adjust the applied amount. Further, if the gap between the polishing agent storage cylinder and the polishing agent is too large, air leakage will occur and the delivery of the polishing agent will not be constant, so that the dimensional accuracy of the polishing agent is strictly required and there is a problem in manufacturing the polishing agent. .

Further, since the abrasive is not integrally fixed to the container when the buff is applied, when the abrasive is consumed and becomes short, the abrasive is blown off by the rotating force of the buff and processed. Occasionally, there was a problem of damaging things. In order to prevent this, the polishing agent had to be discarded, leaving a length of about 50 mm, which was wasteful.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is not to limit the shape of the abrasive to a cylindrical shape, but to use the abrasive and the abrasive. Even if the "fitting" with the container is loose, apply the abrasive to the buff on the part you want to apply with the amount of coating as set, with the abrasive fixed to the container. The present invention intends to provide an automatic abrasive coating device that can be used.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the automatic abrasive coating device according to the present invention has openings at both ends, and an abrasive containing cylinder for slowly containing the abrasive so as to be movable in the longitudinal direction is separated from the buff by a predetermined distance. At this position, a mechanism that clamps the abrasive from the side with the abrasive tightening piece attached to the buff-side tip of the abrasive storage cylinder, and fixes or releases the fixing to the abrasive storage cylinder. A mechanism that advances the abrasive by the set length when the abrasive is fixed on the attachment, and a set time when the abrasive is fixed by the abrasive clamp to apply the abrasive to the buff. A mechanism for moving the abrasive accommodating cylinder in the radial direction of the buff by a direct-acting device that uses a control motor for the set distance and at the same time moving the abrasive accommodating cylinder in the buff width direction by other driving means is provided. It is a thing.

[0007]

[Action]

 The automatic abrasive coating device of the present invention stores the abrasive with the abrasive fastening piece when the abrasive is exposed to the minimum required length from the tip of the cylinder containing only one abrasive. It is fixed to a cylinder, and this cylinder is simultaneously moved in the radial direction and the width direction of the buff by a control motor or the like to apply the abrasive to the peripheral surface of the buff, and the amount of application can be freely controlled.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The mechanism for fixing and releasing the fixing of the abrasive 5 is such that one end of the abrasive clamping piece 1 with a width of about 10 mm is attached to the notch at the tip of the abrasive accommodating cylinder 3 with the hinge 2 and The other end of the abrasive fastening piece 1 is pushed to fix the abrasive 5 from the side surface to the abrasive containing cylinder 3, and the rod 6 of the air cylinder 12 fixed to the main body frame 11 is used to attach the abrasive fastening piece 1. It is a method of releasing the pressing of the coil spring by pressing the tip of the.

At a predetermined position where the polishing agent storage cylinder is separated from the buff, the mechanism for advancing the polishing agent by a set length when the fixing of the polishing agent by the polishing agent fastening piece is released is such that the polishing agent moves forward. This is a method in which the abrasive stopping plate 7 fixed to the main body frame 11 is provided at a predetermined position, and the abrasive is pushed out by the rod 10 of the air cylinder 13 and moved forward until it hits the abrasive stopping plate 7. In some cases, the weight of the abrasive may be advanced until it abuts the abrasive stop plate 7.

In order to apply the polishing agent to the buff, the mechanism for moving the polishing agent containing cylinder in the radial direction and the width direction of the buff at the set time at the set time at the same time is the rotation of the control motor 8 by the sequencer in the radial direction. Is controlled and the ball screw unit 9 converts it into a linear motion to controllably move a minute length, and in the width direction, the rotation of another control motor is converted into a linear motion through a chain and moved.

[0011]

[Effect of device]

 According to the present invention, since the amount of the abrasive applied can be freely controlled, the quality of the polished surface is improved and the consumption of the abrasive is reduced by applying the optimum amount according to the purpose of polishing. .

Further, since the abrasive is fixed when the abrasive is applied to the buff, even if the abrasive is consumed and shortened, the rotating force of the buff does not cause the abrasive to fly off the work piece. There will be no troubles causing damage.

For the above reason, since the length of the polishing agent that cannot be coated anymore and remains and is discarded is about 15 mm, the cost of the polishing agent is reduced.

Further, since the mechanism for delivering the abrasive is not the action of the pressurized air, the shape of the abrasive is not limited to the cylindrical shape, the dimensional accuracy thereof is not strictly required, and the manufacture of the abrasive is easy.
