DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table having a high plane accuracy and a method of mounting the same so that a blade plate can be easily obtained.

[0002]

2. Description of the Related Art FIG. 6 shows a configuration of a typical circular saw cutting machine. In the figure, 21 is a horizontal beam 2
2 is a guide rail attached to the horizontal beam 21 is a saw table that travels and moves on the guide rail 22 is a saw table 23
The cutting unit 25 mounted on the circular saw 27 is rotated by a motor 26. The circular saw 27 is a frame-shaped frame disposed above the horizontal beam 21.

[0003] Reference numeral 28 denotes a horizontal table affixed to a frame 27. A horizontal table 29 is connected to the horizontal table 28, and a blade plate W provided near the projecting position of the circular saw 25 is a table 28.
A plate-shaped workpiece 30 mounted thereon is a clamp member that clamps and fixes the workpiece W to the table 28 and the blade plate 29.
Reference numeral 31 denotes a slit for running the circular saw 25 provided on the blade edge plate 29.

In a cutting machine, the flatness of the table 28 and the blade plate 29 is required to improve the processing accuracy. For this reason, conventionally, the mounting surface 27 of the frame 27 is
a is machined flat by machining, and the table 27 and the blade plate 29 are carefully selected from those having no distortion and high thickness accuracy.

In the above description, the table 28 is used in a durable manner, but the blade plate 29 is significantly worn by the traveling slits 31 due to the movement of the circular saw 25, so that the position is shifted and the blade is frequently ground again. . Therefore, it is necessary to dispose the blade opening plate 29 so that it can be removed from the mounting surface 27a and the movement can be adjusted.

[0006]

Since the conventional cutting machine has a configuration in which the frame 27 is widened widely, it is often manufactured by welding a steel material, and large warping and distortion occur. Therefore, there is a problem that a large-sized machine tool is required to finish it flat, and a great deal of work is required for processing. In addition, even if the machine is machined, if the thickness accuracy of the table and the blade plate is poor, a step is generated. Therefore, a high grade grade must be used, which generally leads to a large increase in cost.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides a method capable of easily obtaining a table and a blade plate having high planar accuracy without requiring machining. It is something to offer.

[0008]

In order to achieve the above object, a method of mounting a table and a blade plate in a machine according to the present invention is as follows.

That is, the gist of the invention is to arrange an adhesive table member and a non-adhesive cutting edge member, both of which are plate-like, on a flat surface of a platen, and to adhere to a surface opposite to the arrangement surface of both members. By arranging the frame member of the machine through the agent, the above-mentioned adhesive is filled in the joint portion and the gap portion between the table member and the blade member and the frame member, and when the adhesive is solidified, the above-mentioned table member Is fixedly bonded to the frame member, and the blade member is detachably joined to the frame member.

According to a second aspect of the present invention, in the method for mounting a table and a blade plate in a machine according to the first aspect, the blade member has at least a non-adhesive surface. I do.

According to a third aspect of the present invention, in the method for mounting a table and a blade plate in a machine according to the first aspect, the blade member has a thin film removably attached to its surface. Make a summary.

According to a fourth aspect of the present invention, in the method for mounting a table and a blade plate in a machine according to the first aspect, the platen surface is configured to suck and hold the table member and the blade member. I do.

By installing the plate-like table member and the blade member on the flat surface of the platen, the installation surface can be arranged with high planar accuracy. When the frame member is installed on the opposite surface to the installation surface of both members, their joining state is not uniform, and a gap partially occurs. At this time, the adhesive
The joints and gaps are filled without gaps and solidified in the same posture. For this reason, the table member and the blade member can be mounted in a required state with high plane accuracy.

[0014] In the case of the third aspect, the blade port member can be constituted by one having the same adhesiveness as the table.

According to the third aspect of the present invention, the inherent distortion of the table member and the blade member can be corrected, and the table member and the blade member can be mounted in this state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for mounting a table and a blade plate in a machine according to the present invention will be described.
FIGS. 1 and 2 show an apparatus for carrying out the method. Reference numeral 1 denotes a base frame. 2 denotes a vacuum-type surface plate disposed on an upper portion of the base frame 1.
Has a box 3 having an open top and a top plate 4 for preventing the open portion, and vacuum means (not shown) is connected to a closed space in the box 3 via a hose 5. A large number of suction ports 6 are formed in the top plate 4.

The top plate 4 is formed of a resin plate, a light metal plate, a resin bonded plate, or the like. The platen surface a formed on the upper surface of the top plate 4 is formed horizontally with high plane accuracy by sufficient rigidity of the box body 3 and the top plate 4. Further, a negative pressure is applied to the platen surface a by vacuum means.

Reference numeral 7a denotes a positioning jig for the table member A disposed at an appropriate place (eight places in the embodiment) on the surface of the base plate a. The table member A is formed of a rectangular divided piece, and these are combined to constitute the entire table. The table member A is made of a vinyl chloride plate, a phenol resin plate, a light metal plate, a resin bonded plate or the like on which an adhesive described later acts. The entire table is divided into two by a long rectangular space b at the center.

B is a plate-shaped cutting edge member disposed on the surface plate a in the above-mentioned space b, and the cutting edge member B is a non-adhesive polyethylene plate, a polypropylene plate or the above-mentioned non-adhesive member on the joining surface. The table member A is made of a plate material, and the same thickness as that of the table member A is used. The blade member B is set at a predetermined position by a positioning jig 7b.

The table member A and the blade member B are corrected for inherent warpage and the like by the action of the negative pressure described above.
It is arranged in close contact with the flat surface plate a. On the opposite surface (upper surface) of the table member A and the blade member B from the installation surface, an adhesive F corresponding to the joining surface of the frame member C of the machine is provided.
Is applied. (See Fig. 4)

The frame member C is formed by welding a steel material such as a square pipe material into a frame shape and has a considerable weight. Therefore, the bonding area is appropriately set so that an excessive load (surface pressure) is not applied to the bonding surface. The position of the frame member C is set by a positioning jig 8 provided on the top plate 4.

When the frame member C is placed on the upper surfaces of the table member A and the blade member B in this manner, the joints Ba and Ca of the frame member B are connected with the table member A via the adhesive F as shown in FIG. And to the blade member B. Even when the joints Ba and Ca rise due to welding distortion and the like, and the gap P is generated as shown in the figure, the adhesive F is filled therein.

As the adhesive, for example, a quick-curing modified silicone-based adhesive (trade name: Konishi Bond Cyflex 20)
When 0) is used, the initial bonding strength (100 N / cm ² ) is obtained when the bonding posture is continued for 30 minutes at normal temperature,
After the elapse of 8 hours, the resin is sufficiently cured to have the required adhesive strength (15
Since it reaches 0 to 200 N / cm ² ), the joining posture can be released, and the process can be shifted to the next machining step.

On the other hand, when the above-mentioned adhesive is used, as a material characteristic, the blade member B does not adhere to the frame member C and is in a state where it can be separated. As a result, the cured adhesive constitutes a plane for attaching the blade member B. The blade member B is attached and fixed by a known means such as a fixing bolt in a later machining step.

The above adhesive has a very small change in volume during the curing process, so that no new stress is generated by bonding. For this reason, the table member A and the blade member B can be mounted with the flatness defined by the platen surface a. The adhesive has a modified silicone resin as a main component and exhibits elasticity. For this reason, the vibration of the table and the cutting unit generated during the cutting can be buffered and reduced.

In the above embodiment, the adhesive F is applied to the blade member B. However, since the blade member B does not need to be fixed to the frame member C, this portion is simply filled. A solidifying agent may be used. In this way, the blade member B can be made of the same adhesive material as the table member A.

In one embodiment, the blade member B has a non-adhesive structure. However, as shown in FIG. 6, an adhesive or non-adhesive thin film Bn is releasably attached to an adhesive blade member body Bm. When the cutting edge member B is formed so that the film Bn side corresponds to the adhesive F, an intended cutting edge plate can be formed mainly of an adhesive material.

In the above embodiment, the table member A
Although the adhesive F is applied to the blade member B side and the mounting operation is performed, it may be performed by applying the adhesive F to the frame member C side.

Further, in one embodiment, when the mounting operation is completed and the frame member C is moved to the subsequent step, the table member A and the blade member B are detached from the platen surface a together therewith. A member equivalent to the blade member B may be fixed and attached to the surface plate a, and only the table member A may be detached. In this case, the original blade member B is attached in a subsequent step.

In one embodiment, the bonding operation was performed with the table member A and the blade member B arranged below, but the frame member C was arranged below and the vacuum-type fixed member facing downward. The mounting operation can be performed in such a manner that the table member A and the blade member B held on the board surface a are pressed from above.

As the adhesive, any commercially available adhesive can be used as long as it can be used at room temperature, has a short drying time, and has the smallest possible volume variation during curing. Can be.

[0032]

As described above, according to the method of mounting the table and the blade plate in the machine according to the present invention, there are disadvantages such as requiring machining for the frame member or using a high-grade table member. Therefore, an excellent effect that a table and a blade plate having a high plane accuracy can be easily formed at a low cost without any problem is exhibited.
