Description

[Detailed description of the invention] The present invention adjusts the cutting thickness of the partner as well as the direction of the partner as the turning machine rotates, and sequentially performs rough finishing and finishing cutting on the workpiece being transferred back and forth. so that it can be rubbed,
Therefore, the present invention relates to a reciprocating cutting type wood superfinishing planer that can produce a perfect finishing effect with one reciprocating cutting.

Previously, Utility Model Application No. 48-86493 or Utility Model Application No. 49-8
No. 1295 discloses a super-finishing planer having a reversible partner.

This device is equipped with one stationary partner and is redirected back and forth to perform one reciprocating cutting process as the workpiece is being fed in forward and reverse directions (reciprocating). With this construction, the determined cutting thickness of the other material does not change during the reciprocating feeding of the material, which has the following disadvantages.

In other words, when performing reciprocating cutting on a super-finishing planer, it is best to use common sense to first uniformly remove the rough surface of the workpiece with rough finishing cutting, and then apply finishing cutting to give the surface a beautiful finish. It is said that

However, in the above-mentioned plane machine, there is no means for adjusting the cutting edge of the partner at all, and when the cutting amount of the partner is set to a cutting amount suitable for rough finishing, it is not possible to scrape off the surface of the workpiece in one reciprocating cut. However, the finished surface will be rough and it will not be possible to obtain a high-quality product, and if the cutting edge is set to a cutting amount suitable for finishing cutting, the workpiece will not be able to be scraped off uniformly in one round trip. However, in order to obtain a smooth and glossy product, several back-and-forth cutting operations are required, which is extremely inefficient.

A' is a cutting thickness adjustment device related to the blade nozzle 15, which includes a tapered operating rod 12 provided in the longitudinal direction of the blade nozzle 15 and uniformly joined to the lower tip thereof, and a device for moving the operating rod forward and backward. The operating rod 12 has both ends provided on the front and rear wall edges 6a, 6b (only one is shown in the figure) of the knife stock 6. It is installed by passing through the hole, and a passive abutting part is provided at each end.

Next, the effects of the present invention will be explained based on the above embodiments.

When cutting the material to be cut using the device of the present invention, first, the set screw 11 in contact with the partner 10 and the cutting thickness adjusting device A having the operating rod 12 are adjusted together. ,
The protruding dimension t1 of the cutting edge during the return stroke (return stroke) in which the workpiece being reciprocated is subjected to finishing cutting is set.

Then, this protrusion dimension t1 is determined as the reference cutting amount.

(Fig. 6) In this case, as shown in the same figure, the projection dimension t1 is determined when the mating joint surface of the operating rod 12 is slightly protruded from the inclined surface 7, and the operating rod 12 at this time is
The position in the advance/retreat direction (the imaginary line position in FIG. 7) is determined as the reference position.

Next, as shown in FIG. 4, the knife stock 6 having the standard cutting amount is mounted on the turning table 4 with the knife stock 6 facing backward, and then the turning table with the reversible motor 33 rotated as desired is rotated clockwise to rotate the knife stock 6. The state shown by the imaginary line in FIG. 5 is turned forward with a predetermined oblique angle shown by the solid line.

In this way, the abutting portion 12a protruding from the front wall edge 6a of the knife stock will engage and be pressed against the sloped surface of the cam plate 37 as the knife stock rotates, and the operating rod 12 will move as shown in FIG. Move in the direction of the arrow.

For this reason, the operating rod 12 is attached to the back side of the companion 10 with the mounting bolt 8.
It is pressed against the clamping force of... and swings the cutting edge d upwards around the cutting edge C, and the cutting edge protrudes further than the standard cutting amount to roughly finish the workpiece. It is set to the blade edge protrusion dimension t2 in the forward feed (forward stroke) of cutting.

(See FIG. 3), and at this time, the other contact portion 12b is pushed outward from the opposite wall edge 6b.

The protruding dimension t2 of the cutting edge is determined by the amount of movement of the operating rod 12, and the cam plate that surrounds the forward and backward movement thereof is manufactured in advance into a predetermined shape.

It is also possible to adjust the abutting portion attached to the end of the operating rod to adjust the range of movement of the operating rod, thereby adjusting the protruding dimension of the cutting edge.

After determining the rough finishing dimensions and finishing dimensions of the partner in this way, the interval of the material feeding path B formed between the table 2 and the material feeding device 23 is determined according to the material thickness, and the material feeding device 2
3 is driven in the direction of the arrow, which is forward rotation, to feed the material to be processed onto the table, the material is fed to the rear of the table by the material feeding device, and is subjected to rough finishing cutting by the forward-facing partner 10. The rough surface is evenly removed.

When this rough finishing process is completed, the reversible motor 32 rotates in the reverse direction, and accordingly the material feeding device 23 is driven in the opposite direction.At the same time, the reversible motor 33 for operating the turning mechanism C is energized, and the turning table 4 is rotated. It turns as shown in the imaginary line in Figure 2, and turns the companion 10 backward at a predetermined oblique angle.

In such a case, the other abutting part 12b of the knife stock 6 is actuated by the gum plate 37, and the operating rod 12 is returned by the amount of movement that was extended for setting the rough cutting dimensions as described above, so that the cutting edge d is adjusted to the standard protrusion. It is set to the amount.

For this reason, the material to be processed is not returned forward on the table by the reverse rotation of the material feeding device, and is then subjected to finishing cutting by a partner, resulting in a glossy and smooth surface.

When finish cutting is finished, the material feeding device is reversed and returns to normal operation, and the turning machine turns its partner forward and sets its cutting edge protrusion to an amount suitable for rough finishing. This will deal with the feeding of the next processing material.

In the above embodiment, the case where the cutting thickness adjustment device is directly related to the partner is explained, but even if the cutting thickness adjustment device is engaged with the plane holder or the blade mouthpiece installed opposite to the partner, the adjustment can be performed. If the operating lever of the device is configured to be moved forward and backward alternately by a force plate, similar effects can be achieved, and the present invention is valid in either case.

As described above, the present invention is designed to control the relative redirection motion accompanying the turning motion of the lathe and the reciprocating motion of the workpiece material accompanying the rotational change of the material feeding device in a manner that allows the workpiece to be machined. In a super-finishing plane machine that performs one reciprocating process on a material, the knife base is supported by a knife stock and mounted on a turning machine, and is also connected to the knife stock in a relative manner. A cutting thickness adjustment device having a tapered operating rod is provided, and a contact portion provided at the end of the operating rod corresponds to a cam plate provided at an appropriate position in a recessed hole into which a turning table is fitted. While the relative cutting thickness can be set alternately to the rough finishing cutting dimension and the finishing cutting dimension with the relative turning movement ζ due to the turning of the lathe, it is possible to perform rough finishing and finishing machining sequentially on the workpiece. The ideal process is to uniformly shave the surface and give it a glossy, smooth and beautiful finish.

However, since an excellent product can be obtained with one reciprocating cutting, the work can be carried out with high efficiency, and it is an industrially useful invention as a reciprocating cutting type wood superfinishing planer.
