Description

[Detailed explanation of the invention] This invention mainly uses tenons of arbitrary shapes on the end and side surfaces of wood.
This invention relates to a surface processing machine used to form a protrusion (protrusion) or a mortise (groove).

Conventionally, when forming wood end face tenons and tenons, the mortises can be formed accurately and efficiently using a corner chisel, but the mortises are formed exclusively by hand; Machining is very complicated and time-consuming, has very low efficiency, and requires a high degree of skill to improve the machining accuracy.

Therefore, this invention was devised to solve such problems, and its purpose is to make the process extremely simple and efficient when forming a tenon or mortise on the end face of wood, without requiring any skill. To provide a surface machining machine that can perform well and accurately machining.

Embodiments of the present invention will be described below based on illustrative drawings.

It is rotatably mounted on an axis via...

On the other hand, the table 2 is configured to be moved back and forth on the bed 1 by a motor 11 provided at one end of the bed 1.

The mechanism for moving this table 2 is well known, and its details will be omitted.

Further, the table 2 may be moved manually.

Further, the screw shafts 12 and 12 are positioned close to each other along the guide grooves 3a and 3a in the guide body 3, so that the screw shafts 12 and 12

Bearings 15, 15 provided on the other end side of the guide body 3 are supported, and a nut body 16 is mounted on the threaded shaft 12, 12 of the bracket.
．． 16 is screwed in, and the nut body 16.16 is supported by a bracket 17.17 fixed to the sliders 2, 2, while a bevel gear 19 is fixed to the end of the threaded shaft 12.12 extending into the gear box 13. .19 and the bevel gear 21.21 inserted and fixed to the drive shaft 20 in the gear box 13, and the drive shaft 20
is interlocked and connected to a reciprocating drive motor 22 attached to the gear box 13, and the drive of the motor 22 rotates the screw shaft 12.12 via the drive shaft 20 and bevel gears 19.19 and 21.21. At the same time, due to the rotation of the screw shaft 12.12, the nut bodies 16, 16
, the holder 5 is configured to reciprocate along the guide body 3 via sliders 4, 4.

Further, a motor 23 with a brake is supported on the holder 5, a small gear 24 is inserted and fixed on the shaft of the motor 23, and a large gear 25 is inserted and fixed on the rotating shaft 6,
The large gear 25 is engaged with the small gear 24, and the rotary shaft 6 is rotated by driving the motor 23.

In the figure, 26 is a torque limiter provided on the shaft of the motor 23.

Further, a motor 28 is fixedly supported by a case 27 attached to the large gear 25 of the rotating shaft 6, and the shaft of the motor 28 and the rear end of the spindle 8 are inserted into the case 27, and the thrust shaft portion is inserted into the case 27. Pulleys 29 and 30 are respectively inserted and fixed in the pulleys 29 and 30, and a belt 31 is stretched between the two pulleys 29 and 30, so that the spindle 8 is rotated by the drive of the motor 28.

The surface processing machine of the present invention is constructed as described above, and the cutter A is attached to the tip of the spindle 8 by the chuck 9, and the cutter A is placed on the end surface of the wood to be processed. The motors 22, 23 are operated according to a predetermined program while rotating the spindle 8 by operation.

For example, when forming a tenon or tenon in the shape shown in FIG. The rotation axis 6 is rotated by 180 degrees by operation.
degree, then interrupting the operation of the motor 23, and operating the motor 22 again to move the holder 5 back by a predetermined amount, and then operating the motor 23 again to rotate the rotating shaft 6 by 180 degrees. Let it happen.

This makes it possible to form a tenon or tenon as shown in FIG.

In this case, instead of rotating the rotary shaft 6 by operating the motor 23, the table 2 may be moved back and forth by operating the motor 11. In this case, both ends of the groove or mortise are machined into a straight line. can do.

Therefore, the present invention can automatically operate and stop the motors 22, 23 or 11.

That is, a member rotated by the motor 22, for example, the screw shaft 1
2, the rotation speed of the drive shaft 20, and the rotation speed of a member rotated by the motor 23, such as the rotation speed of the rotation shaft 6, or the motor 11.
A commercially available pulse encoder (device that reads the rotation speed and sends it as a pulse signal) detects the rotation speed of the rotating member.
The configuration is such that each motor 22, 23 or motor 11 is caused to have a feed puncture using a
．． 23 or the motor 11 is operated based on an arbitrarily set program.

Also, at both ends of the holder 5 or slider 4 in the reciprocating direction,
A forward movement limit switch and a backward movement limit switch are provided, and a movable and fixable contact piece is provided in the guide groove a of the guide body 3, and the motor 22 is operated by contacting the limit switch with the contact piece. In addition, a limit switch is provided on one of the rotating shaft 6 and the holder 5, and two or four contact pieces are provided on the other, and when the limit switch comes into contact with the contact piece, The motor 23 may be configured to operate and stop.

In addition, each limit switch on the holder 5 side and the limit switch on the rotating shaft 6 side are incorporated into the control circuit of each motor 22, 23 so that the motors 22, 23 are operated and stopped in a predetermined order. may be configured.

As explained above, by using the surface machining machine of the present invention, it is possible to reciprocate the table and holder while rotating the spindle, and to eccentrically rotate the rotating shaft. It can be formed easily, efficiently, and precisely without requiring any skill.
