Description

Cutting tool debris removing device and debris removing method

The invention relates to a cutting tool debris removal device and a debris removal method, in particular to a

Pressing will produce chips during cutting; for example, when cutting a screw hole with a tapping knife (screw tapping), the chips will be discharged from the edge of the tapping knife along the chip removal groove; but when the tapping knife is used for a long time Causes blade passivation or poor blade grinding angle, resulting in chip accumulation. The aforementioned chip accumulation will rub against the workpiece to cause poor surface and other problems. Furthermore, because the chip accumulation increases the processing resistance, the tapping knife is used when tapping Fractures and other situations occur; related situations also occur during drilling.

For example, the Republic of China Invention Patent Announcement No. 255842 provides a device for removing drill chips and accumulated chips, which uses convex teeth to scrape the accumulated chips and drill chips from the cutting tool; however, such a method is quite poor. The protruding teeth are intertwined with each other, which is more likely to cause the protruding teeth to be pulled by the accumulated chips and cause serious failure problems.

For example, the Republic of China Invention Patent Announcement No. 457148 provides a drilling and chip removal device that uses flexible deformed body, head and a chip removal part to remove accumulated chips. However, the structure is too idealized. The chip part will continue to rub against the surface of the workpiece to cause scratches; moreover, although it is mentioned that the chip removal part does not contact the bit itself, there is still a chance that the chip accumulation will be caught inside the cutting tool.

For example, the Republic of China Invention Patent No. I445584 provides a chip remover and a drill. However, the chip remover is similar to the structure of a spring. It is well known that the spring has the force of elastic compression. When it is pressed, it will affect the feed of the processing machine. Speed, this type of design is not quite ideal.

How to solve the problem of chip accumulation in cutting tools is a subject actively developed by related industries.

The main purpose of the present invention is to provide a cutting tool debris removal device, which is set on a body by using two sets of parallel springs. When the cutting tool is processed, the debris is removed by contact with the spring to achieve the effect of removing accumulated chips.

Another object of the present invention is to provide a debris removal method using the aforementioned structure, which is characterized in that the cutting tool and the cutting tool debris removal device are arranged perpendicular to each other, and the debris is eliminated without affecting the processing speed.

The structure that can achieve the above purpose includes: a main body and two sets of parallel springs; the main body is a hollow frame with a plurality of in-line positioning portions on the inner side of the body, and the aforementioned positioning portions maintain a spacing ; The aforementioned two sets of springs are located in the positioning portion.

In the embodiment of the present invention, the positioning part is provided with a fine-adjusting unit, which can adjust the elastic tension of the springs, so as to improve the chip-off effect.

In some embodiments, the fine adjustment unit can also be screwed with a pressing unit, and after fine adjustment of the spring tension, the fine adjustment unit is fixed to the body by the pressing unit to prevent the adjustment unit from loosening.

The present invention further includes a debris removal method that uses the aforementioned cutting tool debris remover to place the cutting tool debris remover on a workpiece. The cutting tool debris remover can define all debris Disengagement surface; a processing machine is provided with a cutting tool, the machining direction of the cutting tool and the chip removal surface are perpendicular to each other; after the cutting tool passes through the distance formed by the two springs, the two springs are used to remove the debris Away from the cutting tool.

Through the above structure and debris removal method, the following advantages can be obtained in this case:

1. The structure of the present invention is different from the conventional structure in the way of using coaxial and the same processing direction, which not only does not affect the processing feed rate, but also makes the processing accuracy accurate.

2. The structure of this case can avoid the problem caused by the chip puller and the cutting tool pulling each other.

3. Because the structure of this case is different from the processing direction, it will not rotate with the friction of the cutter on the processed object, so that the surface of the processed object remains smooth and beautiful.

Figure 1 is a perspective view of the structure of the present invention.

Fig. 2 is a state diagram (1) of the present invention.

Figure 3 is a state diagram (2) of the present invention.

Please refer to FIGS. 1 to 3, the cutting tool debris separator 100 of the present invention mainly includes: a body 1 and two parallel springs 2.

As shown in FIG. 1, the body 1 is a frame, and a plurality of positioning portions 11 are provided inside the two corresponding frames of the body 1, and the corresponding positioning portions 11 are respectively connected to the two ends of the two springs. Close the two springs 2 in a parallel state and maintain a distance D between them; as shown in Figure 1, the two ends of the two sets of springs 2 are respectively set in the positioning portions 11; accordingly, the cutting tool The entrained debris passes through the parallel springs 2 and at the same time reverses the cutting tool, that is, the debris can be removed by the two springs 2 to facilitate the processing of another component.

As shown in FIG. 1, the positioning portion 11 is provided with a fine-adjusting unit 12. Rotating the fine-adjusting unit 12 adjusts the elastic tension of the springs 2, for example, the spring 2 is compressed or the spring 2 is expanded, so that the chip separation effect is improved.

Please refer to FIG. 1 and FIG. 2, the fine adjustment unit 12 can also be screwed with a pressing unit 12a, and after fine adjustment of the tension of the spring 2, the fine adjustment unit 12 is fixed to the body 1 by the pressing unit 12A to To prevent the fine-tuning unit 12 from loosening; if the pressing unit 12a is released as described above, the fine-tuning unit 12a can be adjusted into or out of rotation to obtain the tension required by the spring 2.

Please refer to FIGS. 2 and 3. According to the above structure, the present invention further includes a debris removal method, which uses the aforementioned cutting tool debris remover 100 to remove the cutting tool debris remover 100 Placed on a workpiece A, the cutting tool debris separator 100 can define all the chip removal surface B; a processing machine C is provided with a cutting tool E, the cutting tool E processing direction and the chip removal surface B Perpendicular to each other; after the cutting tool E passes through the distance D formed by the two springs 2, the debris is removed from the cutting tool E by the two springs 2.

It can be known from the usage mode of the present invention:

1. The structure of this case can be placed on the workpiece A and is perpendicular to the cutting tool E. Therefore, the structure does not cause resistance during processing, in other words, it allows the processing machine C to protect Processing at the original feed speed can maintain the processing time and prevent the processing machine C from causing problems due to additional processing resistance.

2. The structure of this case can avoid the problem caused by the cutting tool debris separator 100 and the cutting tool E pulling on each other.

3. Because the structure of this case is different from the processing direction, it does not rub and rotate with the cutting tool E on the processed object A, so that the surface of the processed object A remains smooth and beautiful.
