Abstract

The utility model relates to a vehicle cutter, which has a cutter head, a cutter neck and a cutter portion. The cutter has a passage through the cutter head, the cutter neck and the cutter portion, and the passage is provided. The coolant is poured, and the coolant is poured from the shank portion, the cutter head is used for processing the workpiece, and the cutter neck has a length of the cutter neck, and the cutter portion has a shank diameter. The length of the neck diameter is greater than the diameter of the arbor. When the coolant oozes from the passage, the coolant flows along the outer peripheral surface of the shank portion to the neck of the knife, and the neck diameter of the knife neck is increased. The length of the arbor of the shank portion is such that the oozing coolant is blocked by the blade neck, thereby preventing the oozing coolant from flowing to the blade head and returning to the shank portion, thereby not only preventing the rust The lack of corrosion of the cutter head can extend the service life of the cutter.

Description

turning tool

The present invention relates to a turning tool, in particular to an improvement of the structure of the turning tool.

The general lathe processing technology uses various tools to process various types of workpieces. In the process of processing, because the tool is in contact with the workpiece and friction, it is easy to generate high heat. If it is not properly cooled, it will cause damage to the tool and the workpiece, which not only causes the yield to decrease, but also increases the probability of tool damage; therefore, it must be The coolant is used for cooling during processing.

At present, the industry has developed a turning tool structure capable of filling a coolant. Referring to FIG. 1 and FIG. 2, the turning tool 10 has a connecting rod 11 and a cutting head 12, and the cutting rod 11 is provided with a passage 13 therein. One end of the passage 13 extends through the shank 11 to connect the other end of the cutter head 12, and the other end of the passage 13 communicates with the cutter head 12, the passage 13 is provided with a coolant flowing therein, and the cutter is made by the coolant The rod 11 and the cutter head 12 are cooled.

However, when the coolant is injected from one end of the passage 13, a portion of the coolant oozes out from the passage 13, and the oozing coolant drops to the cutter head 12 along the outer peripheral surface of the shank 11, resulting in the turning tool 10. The cutter head 12 is apt to rust, thereby reducing the service life of the turning tool 10.

In view of this, it is indeed necessary to provide a turning tool 10 to prevent the coolant from seeping out of the passage 13.

The purpose of the present invention is to prevent the coolant from seeping out from the passage of the turning tool, thereby preventing the coolant from causing the lack of corrosion of the bit.

To achieve the foregoing objectives, the present invention is a turning tool comprising:

a knife head;

a knife neck having a connecting surface and a blocking surface, the connecting surface connecting the knife head, and the knife neck having a neck length on the blocking surface;

a shank portion is connected to the blocking surface, the shank portion has a shank diameter, and the shank has a path length that is smaller than the length of the shank, so that a blocking angle is formed between the knives and the shank portion.

In a preferred embodiment, the blade head has a first outer peripheral surface, and an obtuse angle is interposed between the connecting surface and the first outer peripheral surface.

In a preferred embodiment, the blade neck further has an extension surface, one end of the extension surface is connected to the connection surface, and the other end of the extension surface is connected to the blocking surface.

In a preferred embodiment, the shank portion has a second outer peripheral surface, the second outer peripheral surface is coupled to the blocking surface, and the blocking angle is a right angle.

In a preferred embodiment, the blade head, the blade neck and the blade portion are sequentially connected, and the turning tool has a passage penetrating along the extending direction, the passage penetrating the blade head, the channel The blade neck and the shank portion, and the two ends of the passage are open along the extending direction.

The length of the neck of the blade neck is longer than the length of the shank, so that when the coolant is injected into the passage and leaks, the oozing coolant can be prevented from flowing to the blade head, and not only can the knife be prevented. The lack of head rust can extend the service life of the turning tool.

Referring to FIG. 3 and FIG. 4, the present invention is a turning tool comprising:

a blade head 20 extending along an extending direction X, the blade head 20 having a first outer peripheral surface 21, the first outer peripheral surface 21 being a circumferential surface of the blade head 20, the blade head 20 being provided with a pair The workpiece is processed;

A blade neck 30 has a connecting surface 31, a blocking surface 32 and an extending surface 33. One end of the connecting surface 31 is connected to the blade head 20. The other end of the connecting surface 31 is connected to the extending surface 33. An obtuse angle θ1 is interposed between the surface 31 and the first outer peripheral surface 21, so that the connecting surface 31 is inclined, and the extending surface 33 extends along the extending direction X, and one end of the extending surface 33 is connected to the connecting surface. 31, the other end of the extending surface 33 is connected to the blocking surface 32, and the blade neck 30 has a neck length 34 on the blocking surface 32;

The first shank portion 40 has a second outer peripheral surface 41 connected to the blocking surface 32. The shank portion 40 has a shank diameter 42 and the shank diameter 42 is smaller than the length of the shank 34. A blocking angle θ2 is interposed between the blade neck 30 and the shank portion 40. In the embodiment, the blocking angle θ2 is a right angle.

Thereby, the blade head 20, the blade neck 30 and the blade portion 40 are sequentially connected, and the turning tool has a passage 50 extending through the extending direction X, and the passage 50 penetrates the blade head 20. The blade neck 30 and the blade portion 40, and the two ends of the channel 50 are open along the extending direction X.

The above is the new structure configuration and its connection relationship. The usage of the new model is as follows:

Referring to FIG. 3 and FIG. 4, when the utility model is used, the cutter head 20 processes the workpiece, and injects coolant from the cutter portion 40 toward the passage 50, and reduces the overall cutter by the coolant. The temperature of the coolant may cause leakage during the filling process, and the leaking coolant flows along the second outer peripheral surface 41 of the shank portion 40, after flowing to the blade neck 30, due to the neck The length of the blade neck 34 of the portion 30 is greater than the length of the blade 42 of the shank portion 40, so that the coolant is blocked by the blocking surface 32 of the blade neck 30, thereby preventing the coolant from seeping to the blade head 20. .

By the blade neck diameter 34 of the blade neck 30 being greater than the shank diameter 42, when the coolant is injected into the channel 50 and leaking, the oozing coolant can be prevented from flowing to the blade head 20, not only It is possible to prevent the rust of the blade head 20 from being lost, and it is possible to extend the service life of the turning tool.
