Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the present utility model is described below by means of specific embodiments shown in the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The utility model provides a novel special tool for ring groove machining, which comprises a tool handle 1, wherein the front end of the tool handle 1 is connected with a blade 2, the tool handle 1 is perpendicular to the blade 2, the rear angle of the tool is 3-5 degrees, a rounding angle is arranged at the joint of the tool handle 1 and the blade 2, the rounding angle is an R30 circular arc, and the rear angle is an included angle between the main rear surface of the tool and a cutting plane.

The knife handle 1 is connected with the knife rest 3. The tool shank 1 is provided with a connecting hole 4, and a bolt connects the tool shank 1 with the tool rest 3 through the connecting hole 4. The number of the connecting holes is 2, and the cutter handle is connected with the cutter rest in a mutually perpendicular mode, so that stable connection of the cutters is realized.

The inner wall of the junction of the knife handle 1 and the blade 2 is provided with a fixed block 7, and the surface of the fixed block 7 is arc-shaped. The surface of the fixed block 7 is provided with a plurality of bulges 5, and the bulges 5 are arranged in parallel. The fixed block is welded on the inner wall of the joint of the cutter handle and the blade, the fixed block is an arc-shaped fixed block, and the fixed block is used for reinforcing the joint of the cutter handle and the blade, so that the abrasion to the joint of the cutter handle and the blade in the process of machining the cooling ring groove can be effectively avoided, and the service life of the cutter is prolonged.
