[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] The following is for reference. Figures 1 to 4 The grooving tool of this application will be described in detail.

[0030] refer to Figure 1 and Figure 2According to an embodiment of the present utility model, the grooving tool includes a tool holder 100 and a cutting head 200. The tool holder 100 is used to mount the grooving tool on a tool holder to clamp the grooving tool, while the cutting head 200 is disposed at one end of the tool holder 100 and is used to perform cutting processing on the workpiece.

[0031] refer to Figure 1 and Figure 2 The tool holder 100 has a positioning plane 110 on its circumferential surface; the tool head 200 is disposed at one end of the tool holder 100 and includes a cutting tooth 210 disposed at the end of the tool head 200 away from the tool holder 100. There is only one cutting tooth 210 on the tool head 200, and an end cutting edge 211 is formed on the cutting tooth 210. The front cutting face 211a of the end cutting edge 211 is arranged parallel to the positioning plane 110.

[0032] It is understood that when the grooving knife of this utility model is positioned and clamped, the positioning plane 110 on the handle 100 is in contact with the mounting surface on the knife holder to complete the positioning and installation of the grooving knife of this utility model. Since the front cutting face 211a of the end blade 211 is set parallel to the positioning plane 110, after the grooving knife is positioned and installed, the front cutting face 211a of the end blade 211 is parallel to the mounting surface of the knife holder, and the front cutting face 211a of the end blade 211 is in the best working state. Therefore, in the grooving knife of this utility model, by aligning the positioning plane 110 on the handle 100 with the mounting surface on the knife holder, after the positioning and installation of the grooving knife of this utility model is completed, the front cutting face 211a of the end blade 211 can be in the best working state. The grooving knife of this utility model does not require the operator to make multiple positioning adjustments during positioning and installation, and the positioning and installation process of the grooving knife of this utility model is simpler and more convenient.

[0033] In some embodiments of this utility model, reference is made to Figures 1 to 4 The cutter head 200 is provided with a refrigerant channel 220. The outlet of the refrigerant channel 220 is located at the end of the cutter head 200 away from the handle 100, and the outlet of the refrigerant channel 220 is located on the axis of the cutter head 200.

[0034] Understandably, since the outlet of the refrigerant channel 220 is located at the end of the cutter head 200 away from the handle 100, and the outlet of the refrigerant channel 220 is located on the axis of the cutter head 200, when the grooving cutter of this utility model is working, the inlet of the refrigerant channel 220 can be connected to the refrigerant output device, and the refrigerant output device can deliver refrigerant into the refrigerant channel 220. The refrigerant is discharged from the outlet after passing through the refrigerant channel 220 to cool the cutting teeth 210. The setting of the refrigerant channel 220 enables the refrigerant output from the refrigerant channel 220 to continuously cool the cutting teeth 210 when the grooving cutter of this utility model is working, so as to reduce the wear of the rake face 211a of the end edge 211.

[0035] Understandably, since the outlet of the refrigerant channel 220 is located on the axis of the cutter head 200, the impact of the outlet of the refrigerant channel 220 on the structural strength of the cutter head 200 can be reduced, and the refrigerant output from the refrigerant channel 220 can be evenly distributed to the end of the cutter head 200 away from the handle 100, so that the refrigerant can evenly cool the end of the cutter head 200 away from the handle 100.

[0036] It should be noted that the refrigerant can be either a cooling gas or a cooling liquid.

[0037] In some embodiments of this utility model, the front cutting face 211a of the end blade 211 is arranged parallel to the axis of the cutting head 200.

[0038] It is understandable that by setting the rake face 211a of the end blade 211 parallel to the axis of the cutter head 200, the present invention can have a higher resistance to chipping when the grooving tool is processing high-hardness materials, thereby extending the service life of the grooving tool of the present invention.

[0039] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The end of the cutter head 200 away from the handle 100 is provided with a first transition surface 230. The first transition surface 230 includes a first transition section 231 and a second transition section 232 connected together. The end of the first transition section 231 away from the second transition section 232 is smoothly connected to the front cutting face 211a of the end cutting edge 211. The end of the second transition section 232 away from the first transition section 231 is smoothly connected to the circumferential side of the cutter head 200. The first transition section 231 is an arc surface with a radius of 1 mm. The included angle α between the second transition section 232 and the axis of the cutter head 200 is between 59.5° and 63.5°.

[0040] It is understandable that the setting of the first transition section 231 and the second transition section 232, with the first transition section 231 being an arc surface with a radius of 1mm and the included angle α between the second transition section 232 and the axis of the cutter head 200 being between 59.5° and 63.5°, can reduce the stress concentration at the cutter head 200 during the cutting process of the grooving tool of this utility model, thereby reducing the risk of the grooving tool of this utility model breaking during the cutting process.

[0041] Preferably, the angle α between the second transition section 232 and the axis of the cutter head 200 is 61.5°.

[0042] In some embodiments of this utility model, the end blade 211 has an axial back angle of 1° and a radial back angle of 1°.

[0043] It is understandable that, since the end cutting edge 211 has an axial clearance angle of 1° and a radial clearance angle of 1°, the cutting teeth 210 can avoid contact with the workpiece in the radial and axial directions of the cutter head 200 during the machining process of the end cutting edge 211, so as to reduce the friction between the grooving tool of this utility model and the workpiece during the cutting process, thereby improving the surface finish of the workpiece after cutting and reducing the generation of burrs on the workpiece surface.

[0044] In some embodiments of this utility model, reference is made to Figure 2 The first rear angle b1 of the end face of the end blade 211 is between 4.5° and 5.5°.

[0045] It is understandable that by setting the first clearance angle b1 of the end face of the end blade 211 between 4.5° and 5.5°, the strength of the end blade 211 can be enhanced, the wear of the clearance face 211b of the end blade 211 can be reduced, and the service life of the grooving tool of this utility model can be extended.

[0046] Preferably, in a specific embodiment of the present invention, the first rear angle of the end face of the end blade 211 is 5°.

[0047] In some embodiments of this utility model, reference is made to Figure 2 The second rear angle b2 of the end face of the end blade 211 is between 11° and 13°.

[0048] It is understandable that by setting the second rear angle b2 of the end face of the end blade 211 between 11° and 13°, the risk of chipping during manufacturing of the end blade 211 can be reduced, thereby improving the consistency of the grooving tool of this utility model.

[0049] Preferably, in a specific embodiment of this utility model, the second rear angle of the end face of the end blade 211 is 12°.

[0050] In some embodiments of this utility model, the tip of the end blade 211 is provided with a rounded corner with a radius of 0.012 mm to 0.013 mm.

[0051] It is understandable that by setting a radius of 0.012mm to 0.013mm at the tip of the end blade 211, the wear rate of the tip of the end blade 211 can be reduced, the stability of the grooving tool of this utility model during cutting can be improved, and the risk of chipping of the tip of the end blade 211 can be reduced.

[0052] In some embodiments of this utility model, the width of the cutting tooth 210 is 1.88 mm.

[0053] Understandably, by setting the width of the cutting tooth 210 to 1.88 mm, the cutting tooth 210 has higher strength, enabling it to cut workpieces with higher hardness.

[0054] In some embodiments of this utility model, reference is made to Figure 4 The end of the cutter head 200 away from the handle 100 is provided with a second transition surface 240. The second transition surface 240 includes a third transition section 241 and a fourth transition section 242 connected together. The end of the third transition section 241 away from the fourth transition section 242 is smoothly connected to the back face 211b of the end cutting edge 211. The end of the fourth transition section 242 away from the third transition section 241 is smoothly connected to the circumferential side of the cutter head 200. The third transition section 241 is an arc surface with a radius of 1 mm. The angle c between the fourth transition section 242 and the axis of the cutter head 200 is 56°.

[0055] It is understandable that the setting of the third transition section 241 and the fourth transition section 242, with the third transition section 241 being an arc surface with a radius of 1mm and the included angle c between the fourth transition section 242 and the axis of the cutter head 200 being 56°, can reduce the stress concentration at the cutter head 200 during the cutting process of the grooving cutter of this utility model, thereby reducing the risk of the grooving cutter of this utility model breaking during the cutting process.

[0056] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
