[0002] A thread milling cutter is a tool used for thread machining on CNC machine tools. Its core feature is a cutting edge with the same tooth profile as the thread being machined. Through helical interpolation motion, the cutter forms a helical trajectory on the workpiece surface, thereby completing the manufacturing of internal and external threads, tapered threads, and large-diameter threads.

[0003] After use, existing thread milling cutters need to be disassembled and replaced according to requirements, for example: CN221516392U discloses a thread end mill with an anti-loosening structure, including a shank, a thread end mill mounted below the shank, and a fixing structure on the outer side of the shank. The fixing structure includes a fixing chamber fixed to the bottom inner wall of the shank. A limiting rod is threadedly connected to one side inner wall of the fixing chamber, and two sets of limiting rods are symmetrically arranged about the vertical center line of the fixing chamber. A baffle is fixed to the outer side of the limiting rod, and one end of the limiting rod penetrates one side wall of the shank. A spring is fixed between the baffle and one side inner wall of the shank. In this invention, by setting up a fixing structure, the thread end mill is fixed to the bottom of the fixing rod. A limiting groove is opened at the top of the fixing rod. The fixing rod is inserted into the interior of the fixing chamber, and the limiting rod fixed inside the fixing chamber by a connecting plate is inserted into the limiting groove to limit the fixing rod. The limiting rod is then rotated.

[0004] The existing technical solutions have the following drawbacks: the existing thread milling cutters are not stable enough when installed, which can easily cause the thread milling cutter to shake during use and affect the performance. Therefore, we propose an anti-loosening thread milling cutter to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-loosening thread end mill to solve the problem mentioned in the background art that the existing thread end mills are not stable enough during use, which easily causes the thread end mill to shake during use and affects the performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A thread milling cutter with anti-loosening features includes: a first connecting rod, and a second connecting rod disposed at the bottom of the first connecting rod, wherein a thread cutting tool is connected to the bottom of the second connecting rod. Also includes: The first connecting rod is connected to a mounting housing on its outer side. A connecting groove is provided inside the first connecting rod, and a second spring is connected inside the connecting groove. A limit plate is provided on the outer side of the second spring. A stabilizing support plate is connected to the outer end of the mounting housing, and a limit component is provided inside the stabilizing support plate. A limiting groove is formed on the outer bottom of the first connecting rod, and a limiting block is connected inside the limiting groove. The outer end of the limiting block is connected to the adjusting rod through a bearing.

[0007] As a preferred embodiment of this utility model, the adjusting rod is connected to the mounting housing by a thread.

[0008] As a preferred embodiment of this utility model, the limiting block is connected to the first connecting rod by means of a limiting groove in a snap-fit ​​manner, thereby limiting the position of the first connecting rod.

[0009] As a preferred embodiment of this utility model, the limiting component includes a positioning rod disposed within a stable support plate, and a first spring is nested on the outer surface of the positioning rod.

[0010] As a preferred embodiment of this utility model, the positioning rod is connected to the stabilizing support plate by means of a first spring and a thread.

[0011] As a preferred technical solution of this utility model, the limiting plate is connected to the first connecting rod by means of a second spring in a sliding manner, and the second spring is evenly spaced at the inner end of the limiting plate.

[0012] As a preferred embodiment of this utility model, the limiting plate is engaged with the mounting housing, and the limiting plate is correspondingly configured with the limiting component.

[0013] As a preferred embodiment of this utility model, the positioning rod is connected through the plate, and the longitudinal section of the stabilizing support plate is an "L" shaped structure.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: the anti-loosening thread cutter, through the dual setting of the limiting block and the limiting plate, can install the thread cutter more stably, increasing the stability of the installation, and at the same time facilitating the disassembly and replacement of the thread cutter; 1. The limiting plate is connected to the first connecting rod by sliding through the second spring, and the second spring is set at equal intervals on the inner end of the limiting plate. After the first connecting rod is aligned with the installation housing, the first connecting rod is slid inside the installation housing. At this time, the limiting plate engages with the installation groove, thereby connecting and engaging the first connecting rod with the installation housing, and installing the first connecting rod. 2. A limiting groove is formed on the outer bottom of the first connecting rod, and a limiting block is connected inside the limiting groove. The outer end of the limiting block is connected to the adjusting rod through a bearing. The limiting block is connected to the first connecting rod through the limiting groove in a snap-fit ​​manner, which plays a limiting role for the first connecting rod. By rotating the adjusting rod, the limiting block is snapped into the limiting groove, thereby increasing the stability of the first connecting rod and the mounting housing. 3. The positioning rod is connected to the stabilizing support plate through a through-hole, and the longitudinal section of the stabilizing support plate is an "L" shaped structure. The positioning rod is connected to the stabilizing support plate in a sliding manner through the first spring. When the positioning rod is pressed, the first spring is compressed, and the positioning rod slides inside the stabilizing support plate. The positioning rod squeezes and compresses the limiting plate and separates it from the mounting housing, thereby separating the first connecting rod from the mounting housing, which facilitates the disassembly of the first connecting rod.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-6 The present invention provides the following technical solution: A thread milling cutter with anti-loosening features: a mounting housing 1, a first connecting rod 2, a second connecting rod 3, a thread cutting tool 4, a limiting block 5, an adjusting rod 6, a limiting groove 7, a stabilizing support plate 8, a positioning insert rod 9, a first spring 10, a mounting groove 11, a connecting groove 12, a second spring 13, and a limiting plate 14. Working principle: When using this anti-loosening thread end mill, first as follows... Figure 2 , Figure 5 and Figure 6 In this process, a second connecting rod 3 is connected to the bottom of the first connecting rod 2, and a threaded cutter 4 is connected to the bottom of the second connecting rod 3, thus forming a complete milling cutter. A mounting housing 1 is connected to the outer side of the first connecting rod 2. A connecting groove 12 is provided inside the first connecting rod 2, and a second spring 13 is connected inside the connecting groove 12. A limiting plate 14 is provided on the outer side of the second spring 13. Since a mounting groove 11 is provided on the outer side of the mounting housing 1, after aligning the first connecting rod 2 with the inside of the mounting housing 1, the first connecting rod 2 slides inside the mounting housing 1. The limiting plate 14 is connected to the first connecting rod 2 by sliding through the second spring 13, and the second spring 13 is evenly spaced at the inner end of the limiting plate 14. At this time, the second spring 13 is compressed, causing the limiting plate 14 to slide inside the connecting groove 12. When the first connecting rod 2 is aligned with the mounting housing 1, the limiting plate 14... The mounting plate 14 engages with the mounting groove 11, thereby connecting and engaging the first connecting rod 2 with the mounting housing 1 for installation. Simultaneously, a limiting groove 7 is formed on the outer bottom of the first connecting rod 2, and a limiting block 5 is connected inside the limiting groove 7. The outer end of the limiting block 5 is connected to the adjusting rod 6 via a bearing. By rotating the adjusting rod 6, the adjusting rod 6 is threadedly connected to the mounting housing 1. When the adjusting rod 6 rotates, it moves inside the mounting housing 1, causing the limiting block 5 to move accordingly. The limiting block 5, connected to the first connecting rod 2 via the limiting groove 7, serves to limit the movement of the first connecting rod 2. When the limiting block 5 moves, it engages with the limiting groove 7, thus connecting the limiting block 5 to the first connecting rod 2. With the setting of the limiting plate 14 and the limiting block 5, the first connecting rod 2 is stably installed to the mounting housing 1. Specific examples Figure 1 , Figure 3 and Figure 4 In the process, by rotating the adjusting rod 6, the adjusting rod 6 drives the limiting block 5 to move. When the limiting block 5 disengages from the limiting groove 7, the outer end of the mounting housing 1 is connected to the stable support plate 8, and the stable support plate 8 is provided with a limiting component inside. Through the setting of the limiting component, the first connecting rod 2 is disassembled, and the positioning rod 9 is connected through the stable support plate 8. The longitudinal section of the stable support plate 8 is an "L" shaped structure. The limiting component includes the positioning rod 9 set in the stable support plate 8, and the outer surface of the positioning rod 9 is nested with a first spring 10. The positioning rod 9 is connected to the stable support plate 8 in a sliding manner through the first spring 10. Pressing the positioning rod 9 compresses the first spring 10, causing the positioning rod 9 to slide inside the stable support plate 8. The limiting plate 14 engages with the mounting housing 1, and the limiting plate 14 corresponds to the limiting component. Pressing the positioning rod 9 compresses the limiting plate 14, causing the second spring 13 to compress and slide the limiting plate 14 inside the connecting groove 12. When the positioning rod 9 compresses and the limiting plate 14 is separated from the mounting housing 1, the first connecting rod 2 is separated from the mounting housing 1, making it easy to disassemble the first connecting rod 2. This is the method of using the anti-loosening thread milling cutter.
