[0002] Cutting tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. Most cutting tools are machine-made, but there are also hand-made ones. Since the cutting tools used in mechanical manufacturing are basically used to cut metal materials, the term "cutting tools" is generally understood as metal cutting tools, and the tools used to cut wood are called woodworking tools. There is also a special type of cutting tools used for geological exploration, well drilling, and mine drilling, called mining tools.

The cross-section of the tool handle is rectangular, the tool head plate is fixedly connected to a side wall surface of the tool handle, the tool head plate is inclined toward the outside of the tool handle, the tool head is located on one side of the cutting point of the tool head plate, and a clearance notch is provided on the other side of the tool head plate.

[0004] The prior art solution also discloses a woodworking tool for processing dovetail grooves, wherein a tool head is connected to a tool handle, the tool head consists of an inverted frustum and a blade, 2-6 blades are arranged on the side wall of the frustum, and the upper part of the blade is higher than the upper surface of the inverted frustum.

[0005] The prior art solution also discloses a thread processing tool, including a long rod portion, a tool groove is opened inside the long rod portion, and a tool handle is clamped inside the tool groove, a tool head is connected to the front end of the tool handle, and a plurality of positioning screw holes are opened on the upper end surface of the tool handle, and two dovetail plates are fixedly connected to the lower end surface of the tool handle on the opposite sides of the screw holes, two dovetail grooves are opened at the lower end of the tool groove, and the dovetail plates are connected to the dovetail grooves, a groove is opened at the upper end of the long rod portion and located directly above the tool groove, and a positioning screw is rotatably connected inside the groove, the positioning screw extends into the tool groove, and the extension section of the positioning screw is threadedly connected to the positioning screw hole.

[0006] However, the existing technical solutions still have problems such as no standard tools for processing special-shaped dovetail grooves, and hand-ground tools cannot meet the size standards, resulting in product processing difficulties, dimensional accuracy not meeting the requirements, unstable product processing dimensions, and severe product tool vibration. Therefore, it is urgent to design and develop a processing tool for special-shaped dovetail grooves to overcome the defects of the existing technology and meet actual application needs. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a processing tool for special-shaped dovetail grooves. In the utility model, through the specific structure and dimensional parameter design of the processing tool, the processing of the special-shaped dovetail groove is formed in one step, thereby ensuring the product quality and the processing pass rate, solving the specific size processing and surface roughness problems of the product, and reducing the occurrence of tool chattering by more than 99%.

[0008] To achieve this purpose, the utility model adopts the following technical solutions:

[0009] The utility model provides a processing tool for a special-shaped dovetail groove, the processing tool comprising a tool handle and a connecting block arranged at one end of the tool handle, a tool head is arranged on the connecting block in a direction perpendicular to the tool handle; the tool head is divided into a vertical portion and a special-shaped portion in sequence along an end away from the connecting block, the special-shaped portion is inclined relative to the vertical portion, and a tip is arranged on a side of the special-shaped portion away from the vertical portion, the angle of the tip is 70-76°, for example, it can be 70°, 70.5°, 71°, 71.5°, 72°, 72.5°, 73°, 73.5°, 74°, 74.5°, 75°, 75.5°, 76°, etc., but is not limited to the listed values, and other values ​​not listed within the numerical range are also applicable, and the tip is used for cutting processing of special-shaped dovetail grooves.

[0010] In the utility model, by designing the specific structure and size parameters of the processing tool, the processing of the special-shaped dovetail groove is formed in one step, which ensures the product quality and the processing qualification rate, solves the specific size processing problem and surface roughness problem of the product, and reduces the occurrence of tool chattering by more than 99%.

The angle of ordinary dovetail grooves is only 24° or 30°, which cannot meet the processing requirements of the drawings. There is no standard for special-shaped dovetail grooves, and the size requirements are high. When hand-ground tools are used to process external cylindrical special-shaped dovetail grooves, the angle of the hand-ground tool, the radius of the tool tip, the width of the blade, etc. are uncontrollable. During the processing, the tool is prone to breakage, the cutting is not smooth, and the bottom of the special-shaped dovetail groove is scratched, which can easily lead to defective products.
