Abstract

PURPOSE:To provide a long-lied belt grinding attachment, capable of grinding a concavely curved surface. CONSTITUTION:A hollow tire 19 consisting of rubber material is attached to the peripheral part of a pulley 10 supported on a base 4 free of rotation. This pulley 10 is stuck to the back of an abrasive belt 12. A work's concavely curved surface is pressed to a part, where the pulley 10 in the abrasive belt 12 is stuck, whereby this concavely curved surface can be ground. Therefore, since this curved surface is ground by the abrasive belt 12 longer than the periphery of the pulley 10 in consequence, such a belt grinding attachment as resistible to continuous grinding or polishing for hours is obtainable.

Next, the operation of the belt polishing apparatus 1 according to the present invention constructed as described above will be described. To grind the concave curved surfaces W 1 and W 2 of the workpiece W, first, the grinding belt driving device 6 is started to rotate the grinding belt 12. At this time, the cylinder 17 is extended, the arm 15 is swung as shown by the solid line in FIG. 1, and the pulley 10 is attached to the polishing belt 12 in advance. Then, as shown in FIG. 5, the concave curved surface W 1 or W 2 of the workpiece W is pressed against the portion of the polishing belt 12 attached to the pulley 10. In this way, the concave curved surfaces W 1 and W 2 can be polished.

The number of rotations of the electric motor 22 during polishing can be changed depending on the material of the workpiece W. When the rotation speed of the electric motor 22 is low, the peripheral speed of the polishing belt 12 is relatively low and the pulley 10 also rotates at low speed. At this time, pulley 1
The tire 19 of 0 remains soft. And
When the rotation speed of the electric motor 22 is gradually increased from low rotation,
As the peripheral speed of the polishing belt 12 increases, the rotation speed of the pulley 10 also increases. When the pulley 10 rotates at a high speed, the centrifugal force applied to the tire 19 increases and the tire 19 made of rubber swells as shown by the chain double-dashed line in FIG. Therefore, the portion of the pulley 10 that is in contact with the polishing belt 12 becomes hard and the outer diameter thereof becomes large.

That is, when the workpiece W is relatively soft, the electric motor 22 is rotated at a low speed to rotate the pulley 10 at a low speed. In this way, the tire 19 of the pulley 10
Remains relatively soft, the amount of polishing is reduced, but the concave curved surfaces W 1 and W 2 easily fit to the polishing belt 12 and a smooth polished surface can be obtained.

When the workpiece W is relatively hard, the electric motor 22 is rotated at high speed to rotate the pulley 10 at high speed. By doing so, the tire 19 inflates as described above, so that the workpiece W can be pressed against the polishing belt 12 with a large force, and the polishing amount is reduced even for the hard workpiece W. Can be polished without.

In order to polish a flat surface or a convex curved surface, the arm 15 is swung as shown by the chain double-dashed line in FIG.
With lower. When the pulley 10 is lowered, the polishing belt 12 is linearly guided from the pulley 9 to the pulley 11 by passing directly above the bearing table 31. Then, for polishing, the workpiece W is pressed against a portion of the polishing belt 12 corresponding to the bearing table 31.

Therefore, in the belt polishing apparatus 1 according to the present invention, the concave curved surfaces W 1 and W 2 of the workpiece W are pressed against the portions of the polishing belt 12 where the pulleys 10 (supporting members) are abutted, so that the concave curved surfaces W are formed. 1 and W 2 are polished. That is, the polishing belt 1 longer than the outer circumference of the pulley 10
Since the concave curved surfaces W 1 and W 2 are polished by 2 , the polishing belt 12 can be polished for a long period of time.

As described above, in the belt polishing apparatus according to the present invention, the support member is rotatably supported with respect to the apparatus main body, and the outer peripheral portion is provided with the hollow tire-like pressure receiving member made of the elastic material. Since the support member is formed by a rotary body and is abutted on the back surface of the polishing belt, the concave curved surface of the workpiece is pressed by pressing the concave curved surface of the workpiece on the portion of the polishing belt where the supporting member abuts. Therefore, since the concave curved surface is polished by the polishing belt longer than the outer circumference of the support member, it is possible to obtain the belt polishing apparatus that can withstand continuous polishing for a long time.

Further, when the peripheral speed of the polishing belt is low, the tire-shaped pressure receiving member of the support member is in a soft state, and by increasing the peripheral speed of the polishing belt, the tire-shaped pressure receiving member swells and comes into contact with the polishing belt. Becomes harder and its outer diameter becomes larger. Therefore, by rotating the polishing belt at a low speed, it is possible to obtain a smooth polishing surface even on a relatively soft workpiece. Further, by rotating the polishing belt at a high speed, the work piece can be pressed against the polishing belt with a large pressing force, so that even a relatively hard work piece can be polished without reducing the polishing amount. That is, the belt polishing apparatus according to the present invention has an effect that even the workpieces having different hardness can be polished by the same polishing belt.
