The abutting surface 212 of one of the tool rails 211 is outwardly convex and curved, and the other abutting surface 212 is flat. The flow guiding grooves 213 respectively extend along the longitudinal direction L and are respectively located on opposite sides of the abutting surface 212. The limiting faces 214 extend along the longitudinal direction L. The setting holes 215 are defined in the abutting surface 212 and are spaced apart from each other along the longitudinal direction L. In the embodiment, the setting holes 215 are all screw holes.

The number of the tool rails 211 may be one, or three or more. The number of the setting holes 215 may also be one to four, or six or more, and the user can adjust the arbitrarily, and is not disclosed by the present invention. The limit is limited.

The side fixing handle 22 extends outward from the holder body 21 in the longitudinal direction L and has a cylindrical shape. The side fixing handle 22 mills four equal-width equidistant cutting planes 221, and the cutting planes 221 are disposed around the central axis of the side fixing handle 22, in two groups, and the cutting planes 221 in each group respectively Formed on opposite sides of the side shank 22. The number of the cutting planes 221 may also be two or more, as long as the cutting planes 221 can be formed on opposite sides of the side fastener 22 and clamped and fixed.

The flow passage 23 is formed inside the seat 2 and has two water outlet holes 231 and a water inlet hole 232. The flow path 23 extends from the end of the side shank 22 to the inside of the shank body 21, wherein each of the water outlet holes 231 is opened to one of the flow guiding grooves 213 of each of the tool rails 211, and the water outlet holes The position of 231 is farther away from the side shank 22. Each of the tool rails 211 also has a plug hole 216. The plug hole 216 is located in the guide groove 213 where the water outlet hole 231 is located, and is used for plugging a plug (not shown). The plug hole 216 is located closer to the side closer shank 22, such that when the water outlet 231 outputs water, the water is blocked by the plug and is only ejected away from the side shank 22.

Each cutter 3 includes a blade body 31, two blades 32, and a slide hole 33. Each of the blades 31 extends in the longitudinal direction L and is substantially elongated, which can be disposed in each of the rails 211, and the opposite ends are gradually converged and have two gripping openings 311. The blade body 31 can be disposed between the limiting faces 214, and one side thereof reliably abuts against and abuts against the abutting surface 212 of the blade holder 2. The two opposite long sides of the blade body 31 respectively abut against the limiting faces 214 of the blade rail 211, and thus the sliding range thereof is restricted to be within the blade rail 211. The gripping ports 311 are respectively formed at opposite ends of the blade body 31 in the longitudinal direction L. The slide hole 33 is opened in the blade body 31 and extends along the longitudinal direction L, and a hole 215 is provided correspondingly.

In the present embodiment, one of the cutters 3 is an end face grooving blade 34, and the other is a cutter blade 35. As the end face grooving blade 34, it is provided on the abutting surface 212 of the blade seat which is curved, so that the blade body 31 and the abutting surface 212 are curved and curved. As the cutting blade 35, it is provided on the abutting surface 212 which is flat in the holder 2, so that the blade 31 has a flat shape.

The blades 32 are respectively mounted on the clamping ports 311. In this embodiment, the blades 32 all adopt the WCMX blade 32, so the clamping ports 311 are generally peach-shaped grooves, and the peach shape is mainly a triangle, and is located at the center of each side. Rising outwards. Each WCMX blade 32 can be locked in the clamping port 311 by a screw.

It is worth mentioning that the conventional WCMX blade 32 is used for drilling. However, the present invention uses the WCMX blade 32 for turning, and is used as a blade for the cutting blade 35, breaking through the limitation of the use of the conventional WCMX blade 32.

It should be noted that the use of the WCMX blade 32 is only one aspect of the present invention. The present invention can also adopt other types of blades. Thus, the shape of the clamping ports 311 depends on the blade shape to be installed. The change is not limited to the peach-shaped groove disclosed in the present invention, and can also be a conventional shape such as a triangle, a rectangle, an arc, a diamond, a bell, a star, or the like. It is worth mentioning that a plurality of blades 31 having different shapes of the clamping ports 311 can be prepared to match the blade of the same type, so that they can be replaced as needed according to the needs, and only two types of the embodiment are disclosed in this embodiment. Tool 3, but in actual use, other types of tools can be prepared in advance, for example, a tool with a rectangular clamping port, a tool with a curved clamping port, a tool with a diamond-shaped clamping port, and a petal-shaped clip. The knife holding the mouth, the tool having the star-shaped gripping port, etc., are not limited by the cutter 3 of the novel peach-shaped holding port 311. Since the shape of the grip opening 311 is conventional, the detailed structure thereof is not described herein.

Referring to FIG. 3 and FIG. 5, the end face grooving blade 34 and the cutting blade 35 are respectively taken during installation, and are respectively placed in the corresponding tool rails 211, and then adjusted according to processing requirements. The position is such that it extends convexly beyond the length of the seat 2 to meet the processing requirements. After the position is confirmed, a lock fastener 4 is inserted into the slide hole 33, and the set holes 215 are respectively locked, and the blade body 31 is fixed to the holder 2. Then, the side shank 22 of the seat 2 is loaded into a lathe holding device 9 (see Fig. 6) to fix the new lathe tool set.

Referring to Figures 6 and 7, the cutting planes 221 of the side fasteners 22 can be clamped and fixed by the clamps 91 of the conventional lathe (i.e., the clamping device 9) (see Figure 6), and the side fasteners 22 themselves. The cylindrical structure is suitable for the clamping device 9 of the CNC computer lathe, and can be disposed in a circular knife hole 921 (see Fig. 7) on a turret 92, so the novel lathe cutter set is suitable for both the traditional lathe and the CNC computer. lathe. Further, the conventional end face grooving blade 1 is taken as an example, and the end face grooving blade 1 for a conventional lathe can be mounted on a CNC computer lathe, and can only be mounted in a rectangular hole 922 thereon, but When mounted in this position, the conventional end grooving knife 1 will not be able to machine its end face in the axial direction of the workpiece unless it is disposed in the circular cutter hole 921, but the appearance of the conventional end grooving cutter 1 is The circular knife hole 921 cannot match and cannot be installed. The side stabilizer 22 of the present invention is designed to achieve the effects of a conventional lathe and a CNC computer lathe.

Thus, the novel lathe cutter set has a two-stage adjustment, the first stage is that the side fixing handle 22 is installed at the position of the clamping device, and the second stage is the position where the cutter 3 itself is mounted on the holder 2 However, the traditional tool can only adjust the length on the clamping device, so the new tool has a larger adjustable distance than the conventional tool, so it has a wider processing depth range and is more suitable for processing. .

Referring to Figures 2, 3 and 5, the novel lathe tool set incorporates a plurality of tools 3, which can use several different tools 3, saving the cost of purchase; further, the cutting blade 35 uses a WCMX blade 32, Compared with the conventional blade 32, it has a price advantage, and provides three cutting faces, which makes the processing cost nearly 10 times. During processing, the machining fluid can be introduced into the water inlet hole 232, and the plugging of the plugs is forced to spray the machining fluid flowing out of the water outlet holes 231 along the flow direction I toward the workpiece, so that it can be immediately processed during processing. The workpiece is cooled to improve the heat dissipation effect.

Based on the above description, the advantages of the new model can be summarized as follows:

1. The cutters 3 of the novel lathe cutter set can be slid on the cutter seat 2 to adjust the exposed length, and can be further extended according to the processing requirements. Compared with the conventional cutters, the novel has a larger size. Adjustable distance, a wider range of processing depths, and more in line with processing needs.

Second, the user can install different tools 3 to the holder 2 at the same time, saving the cost of purchase. Further, the blade 32 having three cutting faces can be further reduced in processing cost by the WCMX blade 32.

3. The blade of the conventional cutter is fixed on the blade body. When the blade is damaged, only the entire set of tools can be replaced. However, each blade 31 of the present invention has two clamping ports 311, which can respectively hold two blades. 32. When one of the blades 32 is completely damaged, the blade 31 can be turned over to allow another blade 32 to continue the machining operation, so that the service life of the single cutter 3 is further extended.

4. The flow channel 23 can pass through the machining fluid, and the machining fluid can spray the workpiece through the guiding of the guiding channel 213, and can instantly cool down during processing, so that the heat dissipation effect is further improved.

5. The side fixing handle 22 is cylindrical and is suitable for a CNC computer lathe, and the cutting plane 221 thereon can be clamped and fixed by the clamping device of the conventional lathe, and is also suitable for a conventional lathe.

Referring to FIG. 8 , the second embodiment of the lathe cutter set of the present invention is substantially the same as the first embodiment, except that the abutting surfaces 212 of the cutter rails 211 are outwardly convex and curved. The abutment faces 212 have different curvatures. The cutters 3 all employ end face grooving knives 34, except that their curved curvatures respectively match the corresponding abutment faces 212.

Since the end face grooving is processed by the end face of the workpiece, and the resulting machining shape is a circular arc shape, the blade body 31 must have an arc structure to avoid interference during cutting. Each of the end face grooving knives 34 has different processing diameters due to the curved curvature of the curved structure. When the nip groove diameter of the workpiece is different, it is necessary to replace the grooving knives with the corresponding machining diameters. The range of the curvature of the end grooving knife is well known and will not be described here.

Thus, the present embodiment transmits the abutting faces 212 of two different curvatures to mount the cutters 3 of different bending curvatures to have a larger range of machining diameters.

Referring to Figures 9 and 10, a third embodiment of the novel lathe cutter set differs from the first embodiment in that the seat body 21 is disc-shaped and has only one tool rail 211. The side shank 22 extends outwardly from the seat body 21 in a direction perpendicular to the longitudinal direction L, that is, the side shank 22 is perpendicular to the trajectory 211. The cutter 3 is a cutter blade 35. Therefore, the bottom surface 212 of the cutter rail 211 is a flat surface. It should be noted that the seat body 21 may also have a shape other than a disc shape, such as an elongated shape, and the number of the tool rails 211 may also be two or more, such as the seat formed in the elongated shape. The top and bottom of the body 21 are opposite sides.

Thus, in addition to the advantages of having a larger adjustable distance and a wider range of processing depth, the present embodiment provides another embodiment, and the user can select according to the processing requirements.

In summary, the cutters 3 of the new lathe cutter set can slide on the cutter seat 2 to adjust the exposed length, and the overall length can be further extended, with a larger adjustable distance and a wider processing depth range. It is wide, so it can achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
