Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting ruler for a vertical traveling circular saw that acts as a reference surface on the lower side of a work when performing cutting work. A vertical traveling circular saw board is commonly called a panel saw, and is widely used in the furniture industry and the fitting industry for cutting large plate materials. This processing machine has a substantially vertical table, and is characteristic in that a work is placed on a lower horizontal ruler and the work is cut in a vertical direction. The configuration will be described below together with the method of use. To perform the cutting process, first, as shown in FIG. 6, a work 33 is placed on the lower mounting ruler 32, and the work 33 is moved laterally on the mounting ruler 32. Then, one end is abutted against the contact ruler piece 34 on the side of the table 31 to be positioned. After positioning, the foot switch 36 operates the pressing member 35 to move the work 33
Is clamped to the table 31. When the setting of the work 33 is completed in this way, the circular saw 37 is automatically driven to rotate, and then the circular saw 33 travels in the vertical direction along a guide rail (not shown). The circular saw 37 is a slit 38 for saw traveling of the table 31.
The work 33 is cut in a vertical direction, that is, at a right angle to the ruler 32 described above. [0005] For cutting the plate material,
Accurate right angle cutting is required. In order to perform this processing with high accuracy, the squareness of the mounting ruler 32 with respect to the saw traveling slit 38 is most important. For this reason, the conventional mounting ruler 32 is manufactured by finishing a sufficiently rigid member with a high-precision machine tool, but this naturally raises the problem of increasing the cost. [0006] In addition, when it is used for a long period of time, it may be warped or distorted by external personnel, but it is difficult to correct it mechanically due to its high rigidity. For this reason, in order to ensure accuracy, replacement and reshaping were inevitable, and maintenance was not easy. SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems found in the related art, and an object of the present invention is to provide a mounting ruler device for a vertical traveling circular saw that is inexpensive to manufacture and easy to maintain. In order to achieve the above-mentioned object, a traveling ruler disk mounting ruler device according to the present invention is configured as follows. In other words, the gist of this is that a mounting member that is integral with the table is placed below the mounting ruler, and a push-up screw that pushes the mounting ruler upward and a pull-down screw that pulls it down. There are a plurality of each. When the mounting ruler is in a middle-height shape, the center portion is adjusted to be pulled down by the pull-down screw while both ends are supported by the push-up screw. Further, when the mounting ruler is in the middle low shape, the linear accuracy is corrected by adjusting the both ends to the pull-down direction while the center part is supported by the push-up screw. In the former case, both ends can be pushed up by the push-up screws for adjustment while the central portion is supported by the pull-down screws. Further, in the latter case, it is also possible to adjust by pushing up the central portion with a push-up screw while both ends are supported by pull-down screws. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a placing ruler device for a traveling circular saw board according to the present invention will be specifically described below.

This cutting unit 1
At 0, a drive motor 11 and a circular saw 12 rotated by the drive motor 11 are provided. The circular saw 12 is protruded from a vertical saw traveling slit 14 provided substantially in the center of the table 3 by a jumping means composed of a pneumatic cylinder 13 and cuts a work material W. The cutting unit 10 is linked with a chain drive type lifting operation means (not shown) to linearly move the circular saw 12. The circular saw 12 has a traveling range from a lower end position shown by a solid line in FIG. 2 to an upper end position shown by an imaginary line. Reference numeral 15 is a reinforcing bone 1a provided on the front frame 1.
The slit cover 15 is provided on the front side in correspondence with the lower end of the slit 14 for saw travel. 16a and 16b
Is a mounting ruler in which an upper ruler surface m is arranged at a lower part of the table 3 so as to be orthogonal to the saw traveling slit 14, and the mounting rulers 16a and 16b are provided on both sides so as to be connected to the slit cover 15. Reference numeral 17 denotes a mounting screw for fastening and fixing the mounting rulers 16a and 16b to the front frame 1, the side frame 4 and the self-supporting frame 6. The mounting screws 18 correspond to one end, the other end and an intermediate portion of each of the mounting rulers 16a and 16b. Then, a plurality of (three in the embodiment) mounting members disposed on the lower side of the mounting member 18
Are fixed to the front frame 1, the side frame 4, and the self-supporting frame 6, respectively. A push-up screw 19 is provided so as to be screwed to the mounting member 18 and provided upward (see FIG. 3). The push-up screw 19 has an abutting portion a at the upper end abutting against the lower surfaces of the mounting rulers 16a and 16b. Reference numeral b is a spanner hook provided on the upper portion of the push-up screw 19, and reference numeral c is a positioning nut screwed to the push-up screw 19. Also in FIG. 3, 20 is a mounting ruler 16
Downward screw provided downward by screwing with a and 16b. The downward screw 19 engages the lower end step portion d with the lower end portion of the mounting member 18. Reference numeral e is a wrench hook provided on the lower end of the down screw 19, and f is a positioning nut screwed onto the down screw 19. Reference numeral 21 denotes a support frame having a U-shape in a side view, which is attached to the front side by fixing the mounting stay at the lower end to the slit cover 15 and the mounting stay at the upper end to the table 3, and a supporting frame 22 by a pair of upper and lower crank arms 23, 23. A material presser 24 operably provided on the material 21 is a pneumatic cylinder that moves the material presser 22 toward and away from the table 3. The material pressing member 22 is a pneumatic cylinder 24.
When the piston rod contracts, the piston rod approaches and clamps the work W on the table surface. Reference numeral 25 denotes a large number of contact ruler pieces arranged on the auxiliary table 7. The contact ruler pieces 25 can be positionally adjusted in the left-right direction, and any piece can be used by protruding onto the table surface. . The configuration of the vertical traveling circular saw board according to the embodiment is as described above, and the cutting of the work W can be performed in the same manner as in the conventional example according to a conventional method. When the product obtained by this cutting process has poor right-angle accuracy and the cause thereof is poor accuracy of the placement rulers 16a and 16b, correction is performed as follows. For example, as exaggeratedly shown in FIG. 4, when the central portion of the right-side mounting ruler 16b is high, the placed work W is inclined and set, so that it is accurate. Right angle cutting is not possible. In this case, the left and right ends are supported by the push-up screws 19 and 19, and the central portion is pulled down by the pull-down screw 20. When the pull-down screw 20 is operated, the push-up screw 19 at the same position is retracted downward so as not to interfere. The operation of the pull-down screw 20 is carried out by the mounting ruler 1
The process ends when the linear accuracy of 6b is obtained. And after the end,
The contact portion a of the push-up screw 19 in the retracted position is in contact with the lower surface of the ruler. At this time, the left and right mounting rulers 16
The ruler surfaces m and m of a and 16b are on a straight line and need to be arranged at a right angle to the saw traveling slit 14. Further, as shown in FIG. 5, the mounting ruler 16b on the right side
When the central portion of the is low, the left and right ends are supported by the pull-down screws 20 and 20, and the central portion is pushed upward by the push-up screw 19. At the time of this push-up adjustment, the pull-down screw 20 in the central portion is released. Then, after the adjustment is completed, it is screwed into a predetermined position so as to be opened. In the above correction example, the case where the mounting ruler 16b is partially bent is described. However, even if the linear accuracy is obtained, if the mounting rulers 16a and 16b are obliquely attached to the saw traveling slit 14, the product accuracy is deteriorated. Also in this case, it is needless to say that accurate right angle accuracy can be obtained by adjusting the push-up screw 19 and the pull-down screw 20 described above. In the above-described embodiment, the straightening means (push-up screw, pull-down screw) is arranged at both ends and the middle of the placing ruler. However, when the placing ruler is longer, or with extremely high accuracy. If is required, the correction means should be provided at a finer pitch. Further, it is a matter of course that the mounting ruler is manufactured with a rigidity within a range that can be corrected. As described above, the placement ruler device for the vertical traveling circular saw according to the present invention corrects the straight line accuracy by straightening.
The right angle accuracy can be obtained. For this reason, it can be provided at low cost without incurring unnecessary costs as in the conventional case. In addition, it has an excellent effect that problems such as warpage and distortion in long-term use can be easily dealt with only by adjusting.
