Description

[Detailed description of the invention] In a super-finishing planing machine in which a material feeding mechanism consisting of a material feeding belt or a material feeding roller is arranged in correspondence with a table equipped with a planer blade, the cutting surface is cut as shown in FIG. There are cases where it is necessary to perform super-finish cutting on a workpiece a with a protrusion C formed on the opposite surface of the cutter.

In such a case, the convex strip C is brought into contact with the material feeding mechanism d and the table e is
When feeding it upward, it often falls over and the entire cutting surface does not come into contact with the table e and the planer blade as shown in the figure. Cutting has been carried out by applying the jig to a large number of workpieces having the same shape, but this method has the drawback of reducing cutting efficiency when applying the jig to a large number of workpieces having the same shape.

In this invention, an auxiliary belt of a relatively narrow width and arbitrary thickness that is engaged with an idling pulley is hung under tension between the idling pulley and a surface corresponding to the table of the material feeding device, and the drive of the auxiliary belt is controlled by the material feeding device. This is related to a super finishing planer for woodworking that is generated by the frictional force generated between the mechanism and the auxiliary belt that replaces the jig, and when the auxiliary belt is not needed, this is It can be removed from the mechanism and used as a normal super-finishing planer, and the structure can be configured to allow the replacement of auxiliary belts of different thicknesses, so super-finishing cutting of workpieces with the above-mentioned structure can be performed using the jig. It has the inventiveness of being able to cut almost the same efficiency as normal shaped workpieces without the need for similar materials.

An embodiment of the present invention will be explained regarding a bottom surface cutting type super finishing planer.

As shown in FIGS. 2 to 4, reference numeral 1 denotes an installation frame which supports a table 2 having a cushion device on its upper part and through which a lifting guide column 5 of an upper frame 4 is inserted.

The upper frame 4 is a handle 7 installed on the installation frame 1.
Elevation is controlled by an elevating screw 6 which is rotated by the elevating screw 6 to move up and down.

A planer blade rotary table 8 is fitted onto the material feeding surface 3 of the table 2, and a planer blade 10 and a blade mouth 11 fit into and support a planer stand 9 attached thereto.

The upper surfaces of the planer blade rotary table 8 and the planer table 9 are at the same level as the material feeding surface 3.

Further, the planer blade rotary table 8 is horizontally rotated to any angle by a rotary grip 12 protruding from the lower surface of the chiffle 2, and is locked at a desired angle.

A pair of left and right material guide rods 13 are provided on the material feeding surface 3, which are in contact with the upper surfaces of the planer blade rotary table 8 and the planer stand 9, and which can also be moved to the opposite side of the running lower surface of the material feeding belt 16, which will be described later. .

The upper frame 4 pivotally supports front and rear rollers 14, 15 corresponding to the table 2, and both rollers 14, 1
The material conveying belt 16 is passed to 5.

Said rollers 14, 15 are driven by motors mounted one or both in the upper frame 4.

The material feeding belt 16 can be replaced with one or more material feeding rollers arranged in parallel.

Reference numeral 1T is a cover attached to the upper frame 6 to cover the outer periphery of the material conveying belt 16, and most of its upper surface is open, and the second cover 18 is detachably fixed to the open part.

19 is a second cover 18 fixed to the upper surface of the upper frame 6.
It is a pivot bracket that protrudes inward, and is L when viewed from the front.
The vertical wall portion 20 is shaped like a shaft 22, and
A rotary plate 23 that swings along the inner surface of the belt 1 is provided, and the material conveying belt 1 is mounted on the rotary plate 23 in parallel with the rollers 14 and 15.
A cantilever shaft 24 protruding above 6 is fixed.

Further, an arc-shaped moving hole 21 is formed in the upright wall portion 20 to match the rotation locus of the cantilevered shaft 24 about the shaft 22, and the rotating plate 23 and the cantilevered shaft 24 are connected to each other from the outside of the moving hole 21. Pass the tightening screw 25 screwed into the center of the .

This tightening screw 25 functions to rotate the rotary plate 23 and the cantilever shaft 24 to an arbitrary vertical angle around the shaft 22 and then fix it at that angle. A handle rod 26 for operation is fixed and projected above the second cover 18.

The second cover 18 has a top portion that does not cover the upright wall portion 20 of the pivot bracket 19, and also has a top portion that does not cover the upright wall portion 20 of the pivot bracket 19.
A long hole is formed on the top surface from which the hole protrudes.

A cylindrical body 27 that is movable in the axial direction is tightly fitted to the cantilever shaft 24, and a lock screw 28 with a handle is inserted.
The inner cylinder 30 of the bearing 29 is fitted together with the unisl so that it can be fixed to the cantilever shaft 24, and the grooved idler pulley 32 is fitted to the outer cylinder 31.

Reference numeral 33 denotes a relatively narrow auxiliary belt which is passed between the outer periphery of the traveling portion of the material conveying belt 16 corresponding to the table 2 and the grooved idler pulley 32, and its wall thickness is appropriately determined.

This auxiliary belt 33 is tensioned by the above-mentioned movement and fixation of the cantilever shaft 24 together with the rotary plate 23,
As the material conveying belt 16 rotates actively, friction causes rotation at the same speed.

In the embodiment described above, when it is necessary to attach the auxiliary belt 33, the second cover 18 and the cover 11 are removed, and the auxiliary belt 33 of an arbitrary thickness is loosely hooked onto the material feeding belt 16 and the grooved idler pulley 32. After passing the cylinder body 30 to the cantilever shaft 24
to the required position in the axial direction, fix it with the lock screw 28, loosen the tightening screw 25, and...
In the past, when the auxiliary belt 33 became tense, the rotary plate 23 and the cantilever shaft 24 were moved and fixed again with the tightening screw 25.
Furthermore, the cover 11 and the second cover 18 are attached as specified.

In this installation state, the material conveying belt 1 corresponding to the table 2
A step corresponding to the thickness of the auxiliary belt 33 is created on the surface of the auxiliary belt 33.

Therefore, when the workpiece a having the structure illustrated in FIG. 1 is fed between the material conveying belt 16 and the table 2 as shown in FIG. Since the part is in contact with the auxiliary belt 33 and is fed very stably, the cut surface can be finished by smoothing it with the planer blade 10.

If the height of the protrusions C is different, the auxiliary belt 33 is replaced with a wall thickness corresponding to the height difference, but if the belt 33 is made of elastic rubber, the difference in height within a certain range of the protrusions C is replaced by the auxiliary belt 33. It can be absorbed by its elasticity.

The present invention has the above-mentioned configuration and action, and can process the workpiece a on which the protrusions C are partially formed at approximately the same speed as when cutting a normal workpiece, and also provides additional assistance. By removing the belt from the material feeding belt or material feeding roller, it has the effect of allowing cutting to be carried out in the same way as a normal super finishing planer.
