Further, a general-purpose processing machine such as a planer may be used to perform groove processing by cutting with a cutting tool or a rotary cutter.

[0003]

However, in the grinder, the arc air gouging, and the plasma gouging, dust is generated and thermal distortion occurs. In addition, work efficiency is reduced. On the other hand, in the cutting process using a planer or the like, when a long object is warped or bent, it is not possible to machine a groove having a constant depth at a constant distance from a reference surface, for example, the upper surface of the long object. An object of the present invention is to provide a side surface grooving device for a long object, which can perform side surface machining even on a long object, can be machined by cutting, and can perform groove machining of a constant depth at a constant distance from a reference surface of the long object. To do.

There is a processing machine and a work fixed bed, one of the processing machine and the work fixed bed is fixed and the other is self-propelled, and the processing machine is a spindle unit having a processing machine main body and a cutter. A spindle frame to which the spindle unit is attached, an upper surface following cylinder that movably supports the spindle frame in the vertical direction and a side surface following cylinder that movably supports the spindle frame in the horizontal direction, and an upper surface following that is attached to the spindle frame. A side surface grooving device for a long object, comprising: a copying roller and a side surface following copying roller.

[0005]

In the above-described apparatus of the present invention, one of the processing machine and the work fixed bed is of the self-propelled type, so that it is possible to perform side processing even on a long product. In addition, since the processing machine has a cutter, it is a cutting process, the processing time is shortened compared to grinding with a grinder, and the generation of dust is also suppressed. Is made to follow the top and side surfaces of the work piece, so even if the long piece warps or bends, the reference surface of the long piece (for example,
It is possible to process a groove with a constant depth from the upper surface).

The processing machine body 18 is composed of a gate-shaped frame that straddles the rail 4. The spindle frame 17 has a first frame portion 17a that is vertically hung from the processing machine body 18 and a second frame portion 17b that is horizontally movably supported by the first frame portion 17a. Cage,
The second frame portion 17b is capable of vertical movement and horizontal movement (work width direction) with respect to the processing machine body 18. First
The frame portion 17a is attached to a rod extending below the upper surface following cylinder (hydraulic cylinder) 14 attached to the processing machine main body 18, whereby it can be moved up and down and pushed downward. You can also The second frame portion 17b is attached to a rod extending in the lateral direction of the side surface following cylinder (hydraulic cylinder) 15 attached to the first frame portion 17a, whereby the second frame portion 17b is movable in the left-right direction, and
It can also be pushed laterally.

The spindle unit 11 is attached to the second frame portion 17b of the spindle frame 17. The spindle unit 11 includes a cutter 16 and
A motor 19 for rotating it and a motor 19
Has a belt for transmitting the rotation of the cutter to the rotation of the cutter 16. The cutter 16 can move vertically and horizontally with respect to the processing machine body 18 together with the second frame portion 17b of the spindle frame. Cutter 16 is work 3
It is applied to the side of and the groove is processed on the side.

The second frame portion 17b (or the first frame portion 17a) of the spindle frame 17 supports the upper surface following copying roller 12. The roller 12 is rotatably pressed against a horizontal reference plane (for example, an upper surface) of the work 3 by a cylinder 14, and the vertical position of the spindle frame 17 and the cutter 16 with respect to the work 3 is copied at a constant distance from the horizontal reference plane. Tell Second frame portion 17 of the spindle frame 17
A side-following copying roller 13 is supported on b.
The roller 13 is rotatably pressed against the side surface of the work 3 by the cylinder 15, and the position of the cutter 16 in the width direction with respect to the work 3 is made to follow a constant distance from the side surface of the work. The upper surface follow-up copying roller 12 and the side surface follow-up copying roller 13 have a position adjusting mechanism (not shown) with respect to the spindle frame 17, and can adjust the vertical position and depth of the groove processed in the work 3. It is like this.
