Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control tool technology, in particular to a high-stability numerical control machine tool tool. Background Art
[0002] The development of cutting tools occupies an important position in the history of human progress. As early as the 28th to 20th centuries BC, China had copper cutting tools such as brass cones and copper cones, drills, and knives. In the late Warring States period (third century BC), copper cutting tools were made due to the mastery of carburizing technology. The drill bits and saws at that time were somewhat similar to modern flat drills and saws. However, the rapid development of cutting tools came in the late 18th century with the development of machines such as steam engines. In 1783, René of France first made a milling cutter. In 1792, Maudslay of Britain made taps and dies. The earliest documented record of the invention of the twist drill was in 1822, but it was not produced as a commodity until 1864. When alloy tool steel was used, the cutting speed of the tool was increased to about 8 meters per minute, and when high-speed steel was used, it was increased by more than two times. When cemented carbide was used, it was more than two times higher than that of high-speed steel. The surface quality and dimensional accuracy of the workpieces cut by cutting were also greatly improved.
[0003] After searching, a new type of CNC machine tool tool with announcement number CN213410367U is found, wherein a mounting cutter head is provided at one end of the CNC external cylindrical tool rod, and the mounting cutter head is fixedly connected to the CNC external cylindrical tool rod, a fixed shaft column is provided above the mounting cutter head, and the fixed shaft column is fixedly connected to the mounting cutter head, a prismatic blade is provided on the outer side of the fixed shaft column, and the prismatic blade is connected to the mounting cutter head through a slot, a cutter head fixture is provided at one end above the prismatic blade, and a hexagonal locking screw is provided inside the cutter head fixture, the hexagonal locking screw is rotatably connected to the CNC external cylindrical tool rod through an internal thread, the mounting cutter head is arranged as a triangular structure, and the height of the mounting cutter head is two-thirds of the height of the CNC external cylindrical tool rod.
[0004] Based on the above patent, the problem that the existing external cylindrical cutting tools in the prior art are often damaged due to excessive feed force or lateral vibration during use, thereby increasing the processing cost, is solved. However, when clamping the tool, a clamp is used for support, resulting in the tool being not stable enough during the processing of the parts, which affects the processing of the parts. In this regard, in response to this technical problem, the present application proposes a high-stability CNC machine tool tool. Utility Model Content

At the same time, the cooperation between the limit bar and the limit groove makes the connection between the tool body and the tool rod more stable, and facilitates the rotation of the tool body to realize the two cutting edges to process parts.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a high-stability CNC machine tool tool, including a tool body, two cutting edges are fixedly connected to the outer walls on the left and right sides of the tool body, the top side of the tool body is connected to a positioning plate through a plug-in assembly, and the bottom side of the tool body is connected to a tool rod through a locking assembly.
[0007] Furthermore, the plug-in assembly includes an insert block located at the bottom side of the positioning plate and a slot located at the top side of the blade body, and the insert block is arranged inside the slot.
[0008] Furthermore, six limiting strips are fixedly connected to the outer wall of the insert block, six limiting grooves are opened on the outer periphery of the slot, and the limiting strips are arranged inside the limiting grooves.
[0009] Furthermore, the locking assembly includes a screw rod located at the bottom side of the insert block and a threaded sleeve located at the left end of the knife rod, and the screw rod and the threaded sleeve are threadedly connected.
[0010] Furthermore, a bolt hole is provided on the top side of the positioning plate.
[0011] Furthermore, the two cutting edges are both made of cemented carbide as raw material.
[0012] Furthermore, the positioning plate is in the shape of a regular prism.

[0014] 1. In the utility model, the tool body is fixed on the tool rod through the cooperation between the screw and the threaded sleeve and the cooperation between the insert block and the slot, and the cooperation between the limit strip and the limit slot makes the connection between the tool body and the tool rod more stable, which is convenient for improving the work efficiency of parts processing.

At the same time, when the insertion When the block 7 is inserted into the slot 9, the cooperation between the limit strip 8 and the limit groove 11 facilitates the more stable fixing of the tool body 1 and the cutting edge 2 on the tool rod 3, thereby improving the stability of the tool in processing parts and improving the efficiency of processing parts. At the same time, when the cutting edge 2 on one side is damaged, the block 7 can be removed. By rotating the tool body 1, since there are six limit strips 8 and six limit grooves 11, after the tool body 1 rotates half a circle, the limit strip 8 can still be adapted to the limit groove 11, thereby facilitating the processing of parts through the cutting edge 2 on the other side, thereby improving the service life of the tool, saving costs and improving the work efficiency of tool replacement.
[0024] The insert block 7 is located at the bottom side of the positioning plate 5 and the slot 9 is located at the top side of the cutter body 1. The insert block 7 is arranged inside the slot 9.

[0025] Specifically, when the insert block 7 is inserted into the slot 9, the cooperation between the limit strip 8 and the limit groove 11 and the cooperation between the screw rod 10 and the threaded sleeve 4 facilitates the more stable fixing of the tool body 1 and the cutting edge 2 on the tool rod 3, thereby improving the stability of the tool in processing parts and improving the efficiency of part processing. At the same time, when the cutting edge 2 on one side is damaged, the shape of the bolt hole 6 and the positioning plate 5 set at the same time is set to be a regular prism, which is convenient for the staff to disassemble and assemble the screw rod 10 and the threaded sleeve 4 through a variety of tools and positioning plates 5. By removing the insert block 7 and rotating the tool body 1, since there are six limit strips 8 and six limit grooves 11, when the tool body 1 rotates half a circle, the limit strip 8 can still be adapted to the limit groove 11, which is convenient for processing parts through the cutting edge 2 on the other side, thereby improving the service life of the tool, saving costs and improving the work efficiency of tool replacement.
[0026] Working principle: when the insert block 7 is inserted into the slot 9, the cooperation between the limit strip 8 and the limit groove 11 and the cooperation between the screw rod 10 and the threaded sleeve 4 facilitates the more stable fixation of the tool body 1 and the cutting edge 2 on the tool rod 3, which is convenient for improving the stability of the tool in processing parts. At the same time, when the cutting edge 2 on one side is damaged, the shape of the bolt hole 6 and the positioning plate 5 set at the same time is set to a regular prism, which is convenient for the staff to disassemble and assemble the screw rod 10 and the threaded sleeve 4 through a variety of tools and positioning plates 5. By removing the insert block 7 and then rotating the tool body 1, since there are six limit strips 8 and limit grooves 11, when the tool body 1 rotates half a circle, the limit strip 8 can still be adapted to the limit groove 11, and the tool body 1 is installed and fixed again through the cooperation between the screw rod 10 and the threaded sleeve 4, which is convenient for processing parts through the cutting edge 2 on the other side, which is convenient for improving the service life of the tool, saving costs and improving the work efficiency of tool replacement.
