[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a panel saw for cutting a plate material such as wood or a synthetic resin panel, and more particularly to a mounting structure of a ruler for holding the plate material at a predetermined position of the panel saw.

[0002]

2. Description of the Related Art The technology related to a panel saw, which is a kind of large electric circular saw, has already been developed and supplied to the market as a specific device. The outline of the panel saw to be implemented will be described.

[0003] As shown in FIG. 1, a panel saw is provided with a surface plate 2 on which a processing plate is mounted on a base 1 which supports the entire apparatus. Above the surface plate 2, a column 3 is erected, and a support plate 4 for supporting the back surface of a processing plate placed on the surface plate 2 is attached to the column 3 at an angle. In the front of the backing plate 4, a support column 5 is provided upright at an appropriate distance from the backing plate 4. A holding plate 6 is provided between the support column 5 and the backing plate 4, and is supported by the support column 5 via a clamp member 7. Sensors 8 for detecting the approach of the human body are attached to both sides of the holding plate 6, and a slit is formed in the center of the holding plate 6 for receiving a disc-shaped saw tooth.

An intermediate portion of the upper and lower clamp members 7 is pivotally connected to the support column 5 so as to be rotatable. One end of the clamp member 7 is rotatably mounted on the holding plate 6, and the other end is rotatably mounted on the drive shaft 9. The upper end of the drive shaft 9 is connected to a piston rod 10 a of an air cylinder 10 attached to the support column 5. By driving the drive shaft 9 in the vertical direction, the holding plate 6 operates via the clamp member 7.

On the other hand, a partial cutout is formed in the backing plate 4 in the left and right width directions, and a guide rail 11 is attached to a lower end of the cutout. An outer diameter portion of the guide rail 11 has a ruler 1 for setting a dimension of a work plate.
2 are slidably and fixably mounted.

The above-mentioned conventional panel saw is an excellent technique in the ability to cut a plate material, but in order to exhibit its performance effectively, the position of the ruler 12 for applying the plate material to the saw blade is guided. It must be fixed in the correct position of the rail 11. In addition, the ruler 12 is
Since the saw blade receives a considerable amount of vibration and impact generated when cutting the plate material, the fixing knob 12 of the ruler 12 is used during the cutting process.
a may be loosened and the position of the contact ruler 12 may be shifted. For this reason, according to the above-mentioned conventional technique, as shown in FIG.
A groove 11a into which the bolt portion 12b of the guide rail 11 fits is formed in the length direction of the guide rail 11, and the fixing knob 12
a, the tip of the bolt 12b is projected from the groove 11a of the guide rail 11, and the abutment ruler 12 is fixed to an arbitrary position on the guide rail 11.

[0007]

However, such a conventional ruler of a panel saw has a guide rail 11
Since the fixing knob 12a is squeezed into the groove 11a of the guide rail 11 and the fixing ruler 12 is fixed to an arbitrary position on the guide rail 11, while the fixing knob 12a is squeezed several times, the groove 11a of the guide rail 11 is recessed. It can cause scratches. In addition, since the width of the plate material to be cut is standardized, the fixing knob 12a of the ruler 12 is often fastened to the groove 11a of the guide rail 11 at almost the same position, and only a part of the groove 11a is large. Easy to make dents. Therefore, when such a dent is large, even if an attempt is made to fix the ruler 12 to a position slightly shifted from the dent portion of the groove 11a of the guide rail 11, when the fixing knob 12a is narrowed, the tip of the bolt 1b is There is a problem that the position of the contact ruler 12 is shifted by being fitted into the concave portion.

Therefore, the present invention has been made to solve such a problem, and the fixing ruler 12 is easily and surely fixed to an arbitrary position of the guide rail 11 and is repeatedly used. Another object of the present invention is to provide a ruler for a panel saw which can hardly damage the guide rail 11 and can perform high-precision cutting for a long period of time.

[0009]

According to the present invention, a ruler for a panel saw is provided movably on a guide rail of the panel saw to support an end of a workpiece for cutting. A pipe member slidably attached to the guide rail, and a ruler extending in a radial direction of the pipe member and capable of abutting an end of the work material. A piece, a C-shaped grip ring provided at one end of the pipe member,
Through a through hole at one ring end of the grip ring,
A male screw shaft that is fastened to a female screw hole at the other ring end, and a gap between an opening formed between the two ring ends fixed to the male screw shaft and rotating the male screw shaft. An adjustable fixed knob is provided.

[0010]

According to the panel ruler of the present invention, first, the pipe member is slid on the guide rail, and the position of the ruler piece is adjusted to the cut dimension of the workpiece. Next, a male screw shaft is passed through the through hole at one ring end of the grip ring,
By rotating the fixing knob, it is tightened into the female screw hole at the other end of the ring. Then, the tip of the male screw shaft is screwed into the female screw hole, and the gap between the ring openings is narrowed. Then, the inner diameter portion of the grip ring sandwiches the outer diameter portion of the guide rail, and the contact ruler is firmly fixed to a predetermined position of the guide rail. Thereafter, the work material is placed on the surface plate of the panel saw, one end of which is brought into contact with a ruler piece, and the work material is cut at a predetermined dimensional position. According to the present invention, when the pipe member is fixed to the guide rail, the inner diameter of the gripping ring and the outer diameter of the guide rail are tightened by surface contact. Almost no dent scratches occur in the tightened part.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 3A is an exploded perspective view of the panel ruler according to the embodiment of the present invention, and FIG. 3B is an assembled perspective view of the panel saw ruler.

As shown in FIGS. 3 (a) and 3 (b), the guide ruler of the panel saw has
0 is slidably mounted. The guide rail 11 is passed through a hole A penetrating in the axial direction of the internal pipe 20. The inner diameter of the outer pipe 21, which is slightly shorter than the length of the inner pipe 20, is rotatably inserted into the outer diameter of the inner pipe 20. A stop ring 22 is fixed to an exposed end of the outer diameter portion of the inner pipe 20 longer than the outer pipe 21 via a fixing nut 22a. The stop ring 22 serves to prevent the outer pipe 21 from falling off the inner pipe 20.

At one end of the inner pipe 20, a gripping ring 20a forming a C-shaped cross section is integrally formed. An opening K is formed between the ring ends facing each other. An elongated hole 20b penetrating the opening K in the vertical direction in FIG. 1 is formed at the ring end of the gripping ring 20a. This long hole 2
Reference numeral 0b denotes a female screw threaded in a hole surface of the lower ring end in FIG. A male screw shaft 23a formed in the axial direction of the fixed knob 23 is screwed into the female screw hole.

On the other hand, at one end of the external pipe 21, a ruler piece 21a for pressing an end of a workpiece placed on the panel saw is integrally formed.

Next, the operation and effect of the panel ruler having the above configuration will be described. First, the guide rule 11 of the present embodiment is slidably mounted on the guide rail 11 of the panel saw, and a plate material such as wood or synthetic resin to be cut is placed on the support plate 4. Next, with the fixing knob 23 loosened, the inner pipe 20 is slid to a position where the ruler piece 21a hits the end piece of the work material, and the fixing knob 23 is squeezed at the hitting position.

Then, the male screw shaft 23a is screwed into the female screw of the grip ring 20a and moves downward, and the fixing knob 2
3 pushes down the upper ring end of the gripping ring 20a in FIG. 1 to narrow the gap of the opening K. As a result, the inner diameter of the gripping ring 20a firmly grips the outer diameter of the guide rail 11, and the inner pipe 20 is firmly fixed to the guide rail 11. That is, the workpiece placed on the backing plate 4 is reliably held by the ruler piece 21a.

Due to such an action, the ruler 21a of the panel saw of the present embodiment is loosened due to vibration or impact generated when the saw blade cuts the work material, and the dimensional accuracy of the work material is deviated. Is completely gone. In this embodiment, the outer diameter of the guide rail 11 is firmly gripped and fixed over the entire inner diameter of the grip ring 20a, so that the outer diameter of the guide rail 11 is not damaged. It is. Therefore, the dimensional accuracy of the processed material can be dramatically improved as compared with the conventional apparatus simply by mounting the panel ruler of this embodiment on the panel saw. Further, in this embodiment, it is possible to maintain the initial performance of the dimensional accuracy of the work material for a long period of time, and the performance deterioration due to the operation time which is often present in this type of apparatus is hardly a problem. Furthermore,
This embodiment is very economically advantageous because it can be easily attached to a prior art panel saw without special modifications.

[0018]

As described above, according to the panel saw ruler of the present invention, the following excellent effects can be obtained. (A) The fixing of the ruler is unlikely to be loosened by the vibration or impact generated when the saw blade cuts the workpiece. For this reason, almost no deviation occurs in the dimensional accuracy of the work material after cutting. (B) Since the abutment rule is clamped and fixed to the guide rail by the grip ring, the surface of the guide rail is not damaged. (C) It is possible to maintain the initial performance of the dimensional accuracy of the work material for a long period of time, and the performance degradation due to the operation time that is common in this type of apparatus is hardly a problem. (D) It can be easily attached to the prior art panel saw without special modification, and is economically advantageous.
