効に消費される欠点がある。(Problem to be solved by the invention) In this case, in a structure in which a processing part for polishing the workpiece is attached to the tip of the spindle perpendicular to the workpiece and the part is simply moved back and forth, the tool generally moves with a creaking noise. This has the drawback that irregular impacts are applied to the tool, causing tool deformation, giving large frictional vibrations to the machine spindle, and processing pressure being wasted ineffectively.

た。 Further, as shown in FIG. 6, at the front dead center (h) and the rear dead center (i) of the reciprocating motion of the tool 11, the indentation 1 of the tool 11 after the acceleration becomes zero mechanically.
2 occurs regularly near the longitudinal dead center (h) (i) of the surface of the workpiece 13, which is a problem in terms of polishing quality.

The purpose of this is to eliminate the squeak of the tool so that it can smoothly reciprocate, and to significantly reduce the machining pressure and speed of the tool near the dead center on at least one side of the tool to prevent the formation of indentations. The object of the present invention is to provide a reciprocating polishing tool that prevents the reciprocating polishing.

ある。 Therefore, when processing pressure is applied in the direction of arrow c in FIG. 1, this force is decomposed into two forces in the directions of arrows d and e on the guide surface 2b. Furthermore, the force in the direction of arrow d is applied in the horizontal direction (arrow f) along the surface of the workpiece W.
is decomposed into a force in the vertical direction (arrow g) and a force in the vertical direction (arrow g).
Of these, the force in the direction of the arrow f promotes the linear reciprocating motion of the entire reciprocating polishing tool in the same direction, providing smoothness, preventing the reciprocating polishing tool from squeaking, and ensuring effective transmission of processing pressure. This is something that can contribute.

ることができる。 On the other hand, as the reciprocating polishing tool T moves forward (moves to the left in Fig. 1), the vertical point 4 of the processing section 4 initially
a is driven by the machining part mounting shaft 2, but when the machining part mounting shaft 2 suddenly stops near the front dead center of the machining part 4, the machining part 4 is moved between the machining part mounting shaft 2 and the machining part 4. 5, it tends to move in the traveling direction due to inertia, and as a result, the elastic body 6 is compressed and each guide surface 2a, 2 is
As it moves along b and 2c and gradually rises,
The work W at the dead center on one side, that is, the front dead center
The processing pressure on the surface and the speed of the processing section 4 are gradually reduced, making it possible to significantly prevent the occurrence of impressions near the front dead center of conventional reciprocating polishing tools.

防止することができる。 Next, when the reciprocating polishing tool T retreats (moves to the right in FIG. 1), the vertical surface 4b of the processing section 4 on the elastic body 6 side is In other words, polishing is performed in a state where the side portions of the convex portions 2' compress the elastic body 6 by a predetermined amount of pressure. In this way, when the machining part mounting shaft 2 suddenly stops near the back dead center of the machining part 4, the machining part 4 moves in the advancing direction along each guide surface 2a, 2b, 2c by the restoring force of the elastic body 6. try to. However, the restoring force of the elastic body 6 at this time becomes smaller in proportion to the moving distance from the initial state equal to the horizontal component of the force in the e direction, so that the processing pressure on the surface of the workpiece W and Since the speed of the processing section 4 gradually decreases, it is possible to prevent the occurrence of impressions near the dead center.

Reciprocating polishing tools T 1 and T 2 are constructed in which mounting shafts 2 and 2 are arranged side by side with each other back to back. With this configuration, as shown in FIG. 4, when the reciprocating polishing tools T 1 and T 2 are all moving forward, one of the reciprocating polishing tools T 1 moves diagonally upward near the front dead center,
Also, when retracting, the other reciprocating polishing tool T 2 moves diagonally upward near the back dead center, so as shown in Fig. It is possible to prevent the occurrence of impressions. At the same time, it goes without saying that the diagonal machining pressure applied to the surface of the workpiece W can prevent the reciprocating polishing tools T 1 and T 2 from squeaking.
