Description

Technical Field

[0001] The utility model relates to precision machining equipment and the cutting tools used thereby, and particularly to a boring tool with smooth avoidance function. Background Art

[0002] Boring tools are mostly used for fillet machining of workstations. However, for current boring tools, when performing fillet machining of small round holes, due to the small diameter of the small round holes, the boring tool needs to rotate a certain angle to correctly perform fillet machining of the small round holes, which is very inconvenient.

[0003] Therefore, it is necessary to provide a boring tool with smooth avoidance function to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a boring tool with smooth avoidance function.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A boring tool with smooth avoidance function includes a tool shank, and a boring tool body is arranged at the end of the tool shank. The boring tool body includes a boring tool connecting body for connecting the tool shank, and an upturned boring tool main body is connected to the end of the boring tool connecting body;

[0007] The boring tool main body has a lower side boring tool machining part, forming a fillet machining structure with one side extending out of the boring hole;

[0008] Corresponding to machining by penetrating into the round hole, a fillet machining structure with one side extending out of the boring hole is formed, and a boring tool machining structure with compliant avoidance is formed.

[0009] Furthermore, the boring tool main body has a corresponding upturned part.

[0010] Furthermore, the corresponding upturned part has an arc-shaped contact part, forming a set structure for preventing the forming surface from scratching the boring tool main body due to arc-shaped butt joint on the other side

[0011] Furthermore, the lower side of the boring tool main body has an extending avoidance notch.

[0012] Furthermore, the height of the boring tool connecting body is 10%-12% lower than that of the tool shank, forming a pre-avoidance and descending structure for the connecting part.

[0013] Furthermore, a stepped sudden drop area is arranged at the connection between the boring tool main body and the boring tool connecting body, forming a secondary avoidance and descending structure for the connecting part.

[0014] Furthermore, the depth of the stepped sudden drop area at the connection between the boring tool main body and the boring tool connecting body is 1-3 mm.

[0015] Compared with the existing technology, the compliant avoidance of the boring tool part of the utility model extends out as set, and can directly perform fillet machining of small round holes quickly and conveniently, ensuring the machining efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment:

[0019] Refer to Figure 1-2 , this embodiment shows a boring tool with smooth avoidance, including a tool shank 1, a boring tool body 2 is arranged at the end of the tool shank, the boring tool body 2 includes a boring tool connecting body 3 for connecting the tool shank, and an upturned boring tool main body 4 is connected to the end of the boring tool connecting body 3;

[0020] The boring tool main body 4 has a lower boring tool processing part 41, forming a boring hole fillet processing structure protruding from one side;

[0021] Correspondingly, it goes deep into the round hole 100 for processing, forming a boring hole fillet processing structure protruding from one side, and forming a boring tool processing structure with compliant avoidance.

[0022] The boring tool main body 4 has a corresponding upturned part 42.

[0023] The corresponding upturned part 42 has an arc-shaped contact part 43, forming a set structure for avoiding the formation surface from scratching the boring tool main body by arc-shaped docking on the other side

[0024] The lower side of the boring tool main body 4 has an extended avoidance notch 44.

[0025] The height of the boring tool connecting body 3 is 10%-12% lower than that of the tool shank 1, forming a pre-avoidance and descending structure for the connecting part.

[0026] A stepped sudden drop area 31 is arranged at the connection between the boring tool main body 4 and the boring tool connecting body 3, forming a secondary avoidance and descending structure for the connecting part.

[0027] The depth of the stepped sudden drop area 31 at the connection between the boring tool main body 4 and the boring tool connecting body 3 is 1-3 mm.

[0028] The lower side of the boring tool connecting body 3 has a connecting body part avoidance notch 32.

[0029] Compared with the existing technology, the compliant avoidance of the present utility model is that the boring tool part protrudes as set, and can directly perform fillet processing of small round holes quickly and conveniently, ensuring the processing efficiency.

[0030] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
