Description

[Detailed description of the invention] This invention is a method for cutting grooves in long materials used as indoor fittings, etc.
The present invention relates to a long material processing machine that can perform tenon cutting and cutting efficiently, and in particular can easily change the cutter height.

Conventionally, a processing machine equipped with a cutter height switching device is disclosed in Japanese Utility Model Publication No. 47-40077.

In this known machine, the operator is required to work while depressing the pedal during the cutting or cutting operation, and the operator's posture during the operation is inconvenient, resulting in accumulation of fatigue for the operator and This also led to a decline in sexual performance.

The present invention was developed with attention to the above points, and a cutter device equipped with a rotary blade is fixed to one end of a support lever that rotates around a support shaft, and the support lever is urged to rotate in one direction. , -Ancient Note By providing a plurality of adjustment screws that contact and engage with the other end of the support lever to suppress rotation of the support lever, and by making the plurality of adjustment screws switchable, The object of the present invention is to provide a long material processing machine whose height can be adjusted, whose switching operation is simple and does not interfere with processing operations, and whose structure is simple.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a perspective view of a processing machine 1 according to the present invention, and the processing machine 1 has a machine main body 2 and a table 3 provided on the top of the main body 2. As shown in FIG.

The main body portion 2 is surrounded by front and rear side walls 4a, 4b and left and right side walls.

A long material such as a shape is processed on the table 3, and 5 is a clamp device that supports and fixes the workpiece S during processing.

Reference numeral 6 denotes an angle adjustment device that rotatably supports the guide bar 7 and adjusts its angle.

Reference numeral 8 denotes a stopper for positioning the workpiece, which is movably attached to the guide bar 7.

As shown in FIGS. 2 and 3, the clamp device 5 includes a lever 10 that rotates via a support pin 9, an operating lever 10a for operating the lever 10, and a clamper that directly presses and supports the workpiece S. 11, a clamp lever 11a for vertical movement of the clamper 11, a clamp screw 12, and a guide pin 13 for guiding the vertical movement of the clamper 11.

The angle adjustment device 6 also includes a knock pin 14 for fixing in the horizontal direction and a clamp 1 for fixing the angle.
5 is provided.

Reference numeral 16 denotes a processing groove drilled on the upper surface of the table 3;
A rotary blade vIJ17 can protrude from 6 onto the table 3 surface.

Further, a guide rod 18 is provided inside the table 3, and the guide rod 1B is slidably supported by a linear motion bearing 19.

Therefore, the table 3 is movable via the guide rod 18.

The moving direction of the table 3, ie, the moving direction of the workpiece S, and the cutting direction of the rotary blade e117 are configured to match.

The rotary blade 11 is attached to a rotating shaft 20 of a motor M, and the rotary blade 17 and the motor M constitute a cutter device 21.

Reference numeral 22 denotes a support lever having a substantially inverted side surface, and is rotatably provided via a support shaft 23.

The support lever 22 has a horizontal portion 22a and a vertical portion 22b.
A motor M, that is, a cutter device 21 is mounted and fixed on the horizontal portion 22a.

Therefore, the support lever 22 is constantly subjected to a force that tends to rotate it in the direction of the side wall 4a due to the weight of the cutter device 21.

On the other hand, an auxiliary block 24 and an auxiliary bar 25 are attached to the lower end of the vertical portion 22b.

26 is a rotating disk provided on the side wall 4a, and the rotating disk 2
Reference numeral 6 rotates via a fixed disk 27 fixed to the side wall 4a.

Reference numeral 2B denotes a pressing rod, which is slidably provided through the rotating disk 26, the fixed disk 27, and the side wall 4a, and its tip can come into contact with the auxiliary bar 25, and its base end has a pressing rod that can be easily pressed. A dish-shaped bushing 29 is attached for this purpose.

30a, 30b, and 30C are arranged radially above the rotating disk 26 (FIG. 3 shows a case in which they are arranged at an angle of 45°).

) with the adjustment screw provided on the rotating disk 26 and the side wall 4.
It is screwed in so that it can move forward and backward through a.

As a clamping means for fixing the adjustment screws 30a to 30C after adjustment to a predetermined position, adjustment screws 30a,
Clamp knobs 31a and 31C are used for the adjustment screw 30C, and a clamp knob 31b is used for the adjustment screw 30b due to its structure.

32 is a switching lever for switching each of the adjustment screws 30a to 30C to a predetermined position.

The tips of the adjustment screws 30a to 30C are brought into contact and engagement with the auxiliary block 24 by switching their positions.

A steel ball 33 is pressed against the fixed disk 27 by a spring 34 and an adjustment bolt 35, and is press-fitted into a recess (not shown) formed in the fixed disk 27, thereby fixing the rotating disk 26 in a predetermined position. to do.

36 is a balance spring consisting of a tension spring.
Both ends thereof are connected to the side wall 4b and the auxiliary bar 25.

This balance spring 36 is connected to the motor M and the support lever 22.
It has the effect of balancing the following.

Note that 37 is a guide ring. With the above-described configuration, in order to determine the height of the cutter device 21, that is, the protrusion height of the rotary blade 17 above the table 3 surface, the adjustment screw 30a is used.
Rotate ~30C and clamp each when the desired cutter height is reached.

Knobs 31a, 31C and clamp nut 31
Fixed by b.

If the protrusion amounts of the adjustment screws 30a to 30C are made different, three types of cutter heights can be determined.

Next, in order to rotate the rotary disk 26, when the button 29 is pressed with a knee or the like, the pressing rod 2B presses the auxiliary bar 25, thereby causing the vertical portion 22. b is pushed toward the side wall 4b, and therefore the auxiliary block 24 is pushed toward the adjustment screw 30a~
30C, the contact state is canceled and the rotating disk 26 can be rotated to any position using the switching lever 32.

Adjustment screws 30A to 30C according to the desired cutter height.
Just select it and move the rotating disk to that position.

In Fig. 2, the adjustment screw 30b and the auxiliary block 2
4 is brought into contact with the cutter height h.

With the cutter height set in this manner, the workpiece S is guided by the guide bar 7 and supported and fixed by the clamp device 5, and then the table is moved and the workpiece S is cut by the rotary blade 17.

The cover 38 prevents cutting debris from scattering during cutting.

FIG. 4 shows an example of cutting a workpiece S.

Note that in this embodiment, three adjustment screws 30a to 30C are provided and are arranged at an angle of 45°, but if there is a plurality of adjustment screws, the number is limited to three. Moreover, it goes without saying that the mounting angle can be set to any desired angle as long as it does not interfere with the work.

As described above, the present invention fixes a cutter device equipped with a rotary blade to one end of a support lever that rotates around a support shaft, and biases the support lever to rotate in one direction. Long material processing in which a rotating disk is provided with a plurality of adjusting screws that contact and engage with the end portion to suppress rotation of the support lever, and the plurality of adjusting screws can be switched by rotating the rotating disk. Since it is a machine, the height of the rotary cutter can be adjusted, the switching operation is simple and does not interfere with machining work, and the structure is simple.
