Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to be used] The present invention relates to a woodworking machine for drilling square mortises and machining square holes.

[Conventional examples and problems]

Corner mortise machining is done by using a K only at corners, which is unique to woodworking machines and is not used at all in metalworking.
It is customary to mark the position where the hole should be drilled and use a corner chisel to drill the hole in the previously marked area, which is extremely inefficient and requires a high degree of skill and skill.

[Problem to be solved]

This invention eliminates the above-mentioned pulling work, sets the workpiece wood in a bed iC using a material fixing tool, and enters the finished dimensions of the workpiece wood, the number of mortises, the size, shape, and shape of the workpiece into the input section. By simply inputting the input information consisting of code symbols corresponding to these, the stopping position and order of the main machining head for drilling each of the several mortises are calculated, and based on this result, the main machining head and the bed are This is to make the relative movement possible and to apply 5Vc so that it can be done automatically without requiring special skill. [Means for solving the problem] This invention provides a feed mechanism in which a machining head equipped with a chuck for attaching a mortising tool and a bed for fixing workpiece wood are relatively moved in a three-dimensional direction. In a square hole processing woodworking machine equipped with each mechanism independently, the length of the bed is a long bed that can support the entire length of the long workpiece wood, and the relative length of the bed to the main processing head is Among these movements, at least each feed mechanism in the length and width directions of the bed is a powered feed mechanism equipped with an independent reversible power source, and on the other hand, the finished overall length dimension, cross-sectional dimension, and number of mortises of the wood to be processed are controlled. , based on the anterior malleolus, according to the specified input signal of the mortise shape.
A square hole processing woodworking machine, characterized in that a control means is provided for starting and stopping the reversible power source in forward and reverse directions, and for sequentially moving and stopping the relative positions of the main processing head and the bed to a mortise processing position. By doing so, the above problem was solved.

[Embodiment]

The invention will now be described on the basis of exemplary embodiments shown in the drawings.

In the figure, 10 is a machine base, on which a horizontally long (approximately 2.5 m) long (approximately 2.5 m) bellows 11 is fixed.

Reference numeral 13 denotes a long feed screw rod provided in the bed 11 or a part of the machine base parallel to the length direction of the bed 11 so as to be able to rotate around an axis, and one end of which is screwed into the screw rod 13. This is a support base for the processing main head which is provided to slide in the longitudinal direction of the bed, and is designed to be able to move over the entire length of the processed wood A being moved forward. The processing main head support base 15
A width direction movable body 16 is provided on the top, which can move at right angles to the length direction of the blade 11, that is, in the width direction. A reversible rotary motor 18 serving as a reversible operating power source is also directly connected to one end of the width direction feed screw rod 17. The width direction movable body 16 includes a machining main head 19 that moves in the axial direction of a spindle 21 that rotates a square hole machining tool B, that is, its drill B.
is provided, and the main processing head 19 is used as a power source to move the processing head 19 toward and away from the processing wood A, or by using pneumatic pressure, the tool B is pressed against the processing wood A using hydraulic pressure, and the spindle 21 is rotated by a motor 22. This is then mortised and retracted after the drilling is completed.

Therefore, the main processing head 19 can move independently in three dimensions with respect to the bed 11, and each is provided with a reversible power source.

On the other hand, in addition to this mechanical device, there is also an input unit 30 that provides designation information on the finished overall length dimension, cross-sectional dimension, number of mortises, and mortise shape of the workpiece wood supported on the bed, and an input section 30 that provides designation information on the finished length dimension, cross-sectional dimension, number of mortises, and mortise shape of the workpiece wood supported on the bed, and the ) 110 from the reference position 12, each mortise position, its size, and the motors 14 and 18 that form the shape are activated or stopped based on the calculation results, and the relative position of the machining main head 19 and the bed 11 is determined. A control means 32 is provided for sequentially moving the position of the main processing head 19 to the mortise processing position of the wood A to be processed on the pet 11 by changing the position.

The above-mentioned input information may be directly input as dimensional numerical values or input as a code symbol of the information.

Furthermore, the calculation means may be one that calculates based on the input information, or one that selects and outputs the calculation results of several types of patterns already stored in a part of the calculation means. shall be included in.

In this invention, the input section 30. The calculation means 31 and the control means 32 use small computers.

The combiator may be installed in a part of the machine base 10, or may be a separate device independent from the mechanical parts, as long as it can send and receive signals to start and stop the power source of each operating part.

In the illustrated example, the axial direction of the chuck is vertical, but there is no difference in this method even if the axial direction of the chuck is horizontal. In addition, the processing main head support base 15 is connected to the machine stand 10.
Even if the bed 11 is fixed to and the bed 11 is moved in the longitudinal direction, the present invention is the same.

The illustrated example also includes a display section 33 that displays input information and calculation results.

[For production]

In the present invention configured as described in 5 above, first, the main processing head 19 is aligned with the reference position 12 of the bed 11.

The wood A to be processed is then fixed at a predetermined location on the bed 11 with both longitudinal directions aligned. Next, when information on the finished overall length, cross-sectional dimension, number of mortises, and mortise shape of the wood A to be processed is inputted through the input section 30, the calculation means 31 determines the processing head to be processed based on the input information. When the machine is operated, the motor is rotated one time based on the command from the control means 32, and the processing main head 19 is cut into the tenon of the workpiece wood fixed to the bed 11. The position trap for drilling holes moves sequentially and then stops.

At this stop position of the main processing head 19, the main processing head 1
9 together with the square hole machining tool B attached thereto, using the fluid cylinder device 20 or manually, move the square hole machining tool B lx ;,'! 'r'f-press;
Further, push it down to a predetermined depth to drill the desired mortise, return it to the retracted position, and repeat this operation every time the main processing head 19 stops, so that the entire length of the workpiece wood A is drill in place.

In the above description, the machining operation of the main machining head 19 with respect to the widthwise movable body 16 was explained using manual or manual instructions as an example. Therefore, the invention is the same as automatic operation, and further automation can be achieved.

〔effect〕

As mentioned above, in this invention, the entire j-pulling operation (
Simply attach the workpiece A to the bed 11,
All you have to do is input some temporary information from the input section, and the main processing head 19 will automatically move to the position where the mortise should be made and stop, so you can do it automatically without any skill required. The work efficiency is further improved compared to conventional manual work by skilled technicians.
