Description

Stable type multifunctional turning tool and processing method thereof Technical Field The invention relates to the technical field of cutting tools, in particular to a stable multifunctional turning tool and a processing method thereof. Background The turning tool is a cutting tool widely applied to machining, and is commonly used for turning, grooving, cutting off, profiling and other machining scenes. The main working principle is that redundant materials are removed through high-speed relative movement between a cutter and a workpiece, and a specific shape or size is formed. In modern machining, the strength, stability and life of the turning tool are critical to machining efficiency and quality. In the prior art, a groove structure is designed on the upper side surface and the lower side surface of the turning tool for sliding positioning, so that the stability and the installation accuracy of the turning tool on the tool apron are ensured. However, such groove structures expose a number of problems during actual machining, resulting in a turning tool performance that is difficult to meet the increasingly demanding machining requirements. 1. The problem of uneven stress is that the turning tool is often subjected to local stress concentration in the machining process due to the limited stress surface of the groove design, and particularly when the turning tool is subjected to high-strength cutting or long-time continuous machining, the turning tool is bent and deformed due to the local stress concentration, so that the machining precision is affected. Particularly, when complex processing such as grooving and profiling is performed, the turning tool has weak bending resistance. 2. The problem of unstable fixation is that the fixation mode of the existing turning tool mainly depends on the combination of the groove and the tool apron, but the structure is easy to displace or loosen in the process of machining, so that the machining vibration is increased. Particularly, in the high-speed cutting, vibration affects the quality of the machined surface and shortens the service life of the turning tool. 3. The positioning structure of the cutter bar normally enables the upper jaw to bear larger stress, and is easy to deform and even has the risk of fracture in the use process of high frequency and high strength. To solve the above problems, the industry generally uses a method of reinforcing the strength of the material or increasing the depth of the groove. However, these methods, while improving the strength and durability of the turning tool to some extent, also present new problems. For example, increasing the material strength may result in significant improvement of the manufacturing cost of the turning tool, and in practical application, too high material hardness may result in increased brittleness and easy breakage, while deepening the groove may increase the bending resistance of the tool, but the deep groove structure results in reduced overall stability of the turning tool, and the turning tool is not easy to accurately align with the tool apron, thereby increasing the installation difficulty. Therefore, how to improve the strength and stability of the turning tool and prolong the service life is a technical problem to be solved by the invention. Disclosure of Invention The invention aims at solving the technical problems of the prior art, and provides a stable multifunctional turning tool and a processing method thereof, so as to solve the problems of uneven stress, unstable fixation and too fast abrasion of the turning tool in the background art.
