Description

[Detailed Description of the Invention] The present invention relates to a chip removal device for a cutting machine.

A conventional example of a chip removal device for a cutting machine is shown in FIGS. 3 and 4. As shown in the figure, the conventional removal device uses a bushing, which is a rotating body that is located at right angles to the rotation direction of the circular saw blade 1 as indicated by the arrow in the figure, and rotates in constant contact with the circular saw blade 1. 2. A brush 3 provided on the outer periphery of the bush 2 and rotating together with the bush 2 removes chips from the cutting edge of the circular saw blade 1 and the tip pocket. In addition, in the same figure, 4 is a shaft holder,
5 is a brush shaft, 6 is a spring, and 7 is a fixing screw.

In the chip removing device configured in this way, the axial end face of the bush 2 is in contact with the outer periphery of the circular saw blade 1, so the bush 2 is rotated in the direction of rotation of the circular saw blade 1 as shown in the figure. Rotate perpendicularly as shown by the arrow. Therefore, as described above, the brush 3 provided on the outer periphery of the bush 2 and rotating together with the bush 2 also rotates in a direction perpendicular to the direction of rotation of the circular saw blade 1. That is, the chips adhering to the circular saw blade 1 were contacted and removed by the brush 3 from the direction perpendicular to the circular saw blade 1. For this reason, a force is applied to the circular saw blade 1 by the bushing 2 that causes the cutting edge to bend against the side surface of the circular saw blade 1, and as this action is repeated, the side accuracy of the circular saw blade 1 deteriorates. , circular saw blade 1 for each
The cutting accuracy will deteriorate. Further, the contact surface of the bush 2 with the circular saw blade 1 wears out because the direction of rotation is perpendicular as described above.

In order to prevent this bush 2 from wearing out, there is a method of using a bush 2 made of soft material, but if a soft material is used, the cutting edge of the circular saw blade 1 will be more likely to bite into the bush 2, so the circular saw blade The force that bends 1 to the side becomes large.

This invention was created in view of the above points,
It is an object of the present invention to provide a chip removal device for a cutting machine that can prevent deterioration of the cutting accuracy of a circular saw blade.

In other words, the present invention places the brush parallel to the circular saw blade.
The circular saw blades are arranged so as to be in contact with each other under a predetermined pressure, and are rotated in parallel to the direction of rotation of the circular saw blade.

Hereinafter, the present invention will be explained based on the illustrated embodiments. An embodiment of the present invention is shown in FIGS. 1 and 2. FIG. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, the brush 3a is arranged parallel to the circular saw blade 1 so as to be in contact with it under a predetermined pressure, and is rotated parallel to the rotating direction of the circular saw blade 1. By doing this, the brush 3a rotates parallel to the circular saw blade 1 to remove chips, and the cutting edge of the circular saw blade 1 is placed on the side of the circular saw blade 1 as in the conventional case. It is possible to obtain a chip removing device for a cutting machine that prevents deterioration of the cutting accuracy of the circular saw blade 1 and prevents the circular saw blade from being bent.

That is, the outer periphery of a rotating body 2a having a brush 3a on its outer periphery is fixed to the main body 8, and a fulcrum pin 10 into which a spring 9 is inserted is inserted into the fulcrum pin 10 and rotated about this fulcrum pin 10. A holder 11, which is fitted into a hole parallel to the fulcrum pin 10 and supports the rotating body 2a,
The elastic force of the spring 9 of the pressure application device constituted by the rotatable shaft 12 is used to bring the circular saw blade 1 into contact with the outer periphery of the saw blade 1 with a predetermined pressure. The brush 3a provided on the outer periphery of the rotating body 2a is positioned parallel to the circular saw blade 1 by the holder 11.
This is done by means of an adjusting screw 13 screwed into the. In the figure, 14 and 15 are fixed pins that restrict the rotation of the spring 9, and 16 is a fixed pin that restricts the rotation of the spring 9.
1 is a retaining washer, and 17 is the shaft 12.
18 is a washer fixed to the shaft 12 in order to give elastic force to the spring 17, and 19 is a washer that is fixed to the shaft 12 to attach the rotating body 2a and the brush 3a located on the outer periphery of the rotating body 2a. 20 is a fixing screw for preventing rotation of the adjusting screw 13. By doing this, the elastic force of the spring 9 causes the holder 11, shaft 12, rotating body 2a, and brush 3a to rotate toward the circular saw blade 1 using the fulcrum pin 10 as a fulcrum, and the outer periphery of the rotating body 2a is rotated. The rotating body 2a comes into contact with the outer periphery of the circular saw blade 1 and rotates together with the circular saw blade 1. With this rotation, the rotating body 2a is located on the outer periphery of the rotating body 2a and comes into contact with the circular saw blade 1 under a predetermined pressure. The brush 3a arranged in parallel rotates in parallel to the rotating direction of the circular saw blade 1 to remove chips from the circular saw blade 1, thereby preventing deterioration of cutting accuracy of the circular saw blade 1. and rotating body 2a
can prevent wear. Although an attempt is made to pull the brush 3a of the spring 17, the rotating body 2a, and the shaft 12 toward the adjustment screw 13, the adjustment screw 13
Since the shaft 12 is positioned by this, the positional relationship between the brush 3a and the circular saw blade 1 can be adjusted.

As mentioned above, the present invention removes chips from the cutting machine without bending the cutting edge of the circular saw blade inward, so chips can be removed without deteriorating the cutting accuracy of the circular saw blade. It is possible to obtain a chip removal device for a cutting machine that can prevent deterioration of cutting accuracy of a circular saw blade.
