Description

[Detailed explanation of the invention] (Field of industrial application)
That is, the present invention relates to an NC router plate material mounting jig that allows the edge portion to be processed using an NC router.

(Prior art) For example, in order to apply a comb-like muntin, that is, a locking process to the ends of drawer plates, conventionally a vise is integrally attached to the table, and a large number of plates are piled up using this vise. A large number of cutters are arranged at a predetermined pitch in accordance with the width of the end of the board on the main shaft, which is tightened and fixed and placed horizontally along the table, and each cutter locks the entire end of the board at once. A special plane arrived.

(Problems to be Solved by the Invention) The above-mentioned conventional method had the drawback of increasing equipment costs because it was a dedicated machine for rocking processing.

Therefore, there is a way to utilize a highly versatile NC router, but in this case, the plate material is positioned in a predetermined direction so that it can be processed with the NC router, and
A jig that can accommodate changes in the number and length of plate materials is required. Moreover, this jig needs to be removable from the table so as not to impair the versatility of the NC router.

In view of the above-mentioned circumstances, the present invention aims to provide a mounting jig for plate materials suitable for NC routers.

(Means for Solving the Problems) In order to achieve the above object, the present invention is constructed as follows.

That is, a pair of plate mounting jigs are provided on the table to support both ends of the plate, and each plate mounting jig is
A rail that spans the top of the table, a stopper that stands up and is fixed at one end of the rail, a movable support that faces the stopper and is slidably supported on the rail, and the movable support that can be attached to and detached from the rail. Each has a locking tool for locking, a pressurizing mechanism that is attached to the movable column and operates in a direction toward and away from the stopper, and a clamping tool that removably clamps both ends of the rail to both ends of the table. It is structured as follows.

(Function) Since the present invention has the above configuration, when both ends of the plate are interposed between the stopper and the pressure mechanism of each plate mounting jig, and each pressure mechanism is operated in the direction of the stopper, Both ends of the plate are pressed and fixed to the plate receiving surface of each arm.

Further, by operating the locking tool, the pressure mechanism can be moved and adjusted to any location on the rail.

Further, by operating the clamping tools, the intervals between the respective plate mounting tools can be adjusted to any desired distance.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a sectional side view of the main part thereof.

1 and 2, reference numeral 1 is a table of the NC router, and this table 1 is operated in the X-axis direction (left-right direction in FIG. 1) and Y-axis direction (left-right direction in FIG. 1) by an X-axis motor and a Y-axis motor (not shown) It is movable in the left-right direction (in FIG. 2).

As shown in FIG. 1, a pair of plate material mounting jigs A and B, which clamp and support both ends of a plate material W, are mounted on the table 1 so as to be spaced apart in the left-right (X-axis) direction.

The plate material mounting jigs A and B both have substantially the same structure, and the plate material mounting jig A on the left side will be described in detail with reference to FIG. 2 as a representative.

A rail 2 is slidably supported on the upper surface of the table 1, and a stopper 3 is fixed to the left end of the rail 2 in an upright manner.

The right side of the stopper 3 is formed into a vertical and smooth plate receiving surface 3a.

In addition, a movable support 4 is installed on the right side of the rail 2 on the left and right (Y
Mounted so that it can slide in the axial direction. This movable support 4
is tightened and fixed to the rail 2 at an arbitrary position by a locking tool 5 consisting of a set screw attached to the right side thereof.

A pressure mechanism 6 is attached to the movable column 4.

This pressurizing mechanism 6 has a screw shaft 7 fitted to the movable column 4 so as to be progressively movable in the left and right directions, a pressurizing plate 8 fitted to the left end of the screw shaft 7 so as to be rotatable but immovable in the axial direction, and Attach the operating lever 9 to the right end of the pin 9.
They are connected in a swingable manner via a.

Further, as shown in FIG. 1, a bracket 10 is fixed to the rail 2 of the left plate mounting jig A so as to protrude leftward, and an end face ruler 11 is rotated by a pin 12 at the left end of the bracket 10. Install movably.

When attaching the plate material W to the plate material mounting jigs A and B, this end face ruler 11 is rotated in the direction of arrow P in FIG. This is for positioning in the direction.

A pair of clamping tools 13 are provided at both ends of the rail 2 described above.

As shown in FIG. 2, this clamping tool 13 has an L-shaped clamp arm 1 that hangs downward from the rail 2 and then bends inward along the lower surface of the table 1.
4 and 14 are fixed together, setscrews 15 and 15 are screw-fitted to the lower sides of the clamp arms 14 and 14, and a push screw 16 is attached to the hanging side of the right clamp arm.

In addition, 20 in the figure is the head of the NC router,
It is moved up and down by a Z-axis motor (not shown), and disk-shaped cutters 21 are attached to the main shaft thereof, arranged vertically at a predetermined pitch.

Further, reference numerals 22 and 22 in Fig. 2 are waste plates, which are fixed to the stopper 3 and the pressure plate 8 with screws 23 (Fig. 1), and come into contact with the outermost plate material W' during machining. This prevents loss of W'.

Next, the manner of use of the above embodiment will be explained.

First, set the interval between each plate mounting jig A, B to the plate W.
Adjust the spacing to be slightly smaller than the length of the clamping tool 1.
Tighten the set screw 15 and set screw 16 of No. 3 to fix both to the table 1.

Next, each movable column 4, 4 is slidably adjusted along the rail to set the distance between each movable column 4, 4 and each stopper 3, 3 to a predetermined value, and each locking member 5, 5 is tightened to fix it to the rail 1.

In this state, after rotating the end face ruler 11 in the direction of arrow P in FIG.
3 and the pressure plates 8, 8, and one end thereof is brought into contact with the end surface 11a at the tip of the end surface ruler 11.

Next, each operating lever 9, 9 is operated to move each pressure plate 8, 8 to the left, that is, in the direction of stoppers 3, 3, via each screw shaft 7, 7, to clamp and fix both ends of the plate material W, and then The end face ruler 11 is rotated outward as shown in FIG.

As a result, as shown in FIG. 1, each plate material W is clamped and fixed with both left and right end portions W1 and W2 to be processed exposed outward from the respective plate material mounting jigs A and B.

When the NC router is started in this state, the cutter 20 is rotated, and the program signals control the movement of the table 1 in the X-axis and Y-axis directions and the movement of the head 20 in the Z-axis direction. At this step, the left end W1 of the plate W, and then the right end W2 of the plate W, are rocked into a comb-teeth shape.

Then, by loosening the set screw 15 and push screw 16 of the clamping tool 13, the plate material mounting jigs A and B can be easily removed from the table 1, and thereby other workpieces other than the plate material W can be processed. be able to.

(Effects of the invention) As is clear from the above explanation, according to the invention, plates can be positioned and mounted in a direction that can be processed by an NC router, and changes in the number and length of plates can be easily accommodated. In addition, since it can be easily attached to and detached from the table, the locking process of plate materials can be easily and accurately performed without compromising the versatility of the NC router.
