Description

Technical Field

[0001] This utility model belongs to the field of CNC cutting tool technology, and relates to a diamond thin film insert, and particularly to a fastening type diamond thin film insert. Background Technology

[0002] Diamond thin film inserts are high-performance cutting tools made by depositing a diamond thin film on the surface of a tool substrate using chemical vapor deposition technology. They combine the hardness of diamond with the toughness of the tool substrate, giving them significant advantages in the field of precision machining.

[0003] Existing diamond thin-film cutting tools are usually installed and fixed by screws and nuts. The surface of the screw contacting the tool is smooth, and the tool position is positioned solely by the tightening force of the nut. This results in poor tool positioning stability and easy occurrence of tool angle deflection. Therefore, designing a fastening type diamond thin-film cutting tool is of great significance. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a fastening type diamond thin film blade.

[0005] The purpose of this utility model can be achieved through the following technical solution: a fastening type diamond thin film blade, characterized in that it includes a blade body, the blade body is provided with a mounting hole, the blade body is provided with a movable groove communicating with the mounting hole, an arc plate is slidably arranged in the movable groove, and a friction pad is fixedly arranged on the inner side of the arc plate.

[0006] In the aforementioned type of fastening diamond film blade, the blade body has a guide groove that communicates with the movable groove inside, and a threaded sleeve is fixedly provided on the outer side of the arc plate, and the threaded sleeve is slidably disposed in the guide groove.

[0007] In the aforementioned type of fastening diamond film cutting tool, a slide rod is rotatably provided on the inner wall of the cutting tool body. A knob block is fixedly provided at one end of the slide rod, and the knob block is located on the outside of the cutting tool body. A threaded rod is fixedly provided at the other end of the slide rod, and the threaded rod is used in conjunction with a threaded sleeve.

[0008] In the aforementioned type of fastening diamond film cutting tool, a limiting groove is formed on the inner wall of the cutting tool body, and a limiting plate is fixedly provided on the surface of the slide rod, with the limiting plate located within the limiting groove.

[0009] Compared with existing technologies, this fastening type diamond thin film blade increases the friction between the blade body and the screw by setting a friction pad, making the blade less prone to deflection. Attached Figure Description

[0014] In the diagram, 1 is the blade body; 2 is the mounting hole; 3 is the movable groove; 4 is the arc plate; 5 is the friction pad; 6 is the guide groove; 7 is the threaded sleeve; 8 is the slide rod; 9 is the knob block; 10 is the threaded rod; 11 is the limit groove; and 12 is the limit plate. Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1-4 As shown, this fastening type diamond thin film blade includes a blade body 1, a mounting hole 2 on the blade body 1, and a movable groove 3 communicating with the mounting hole 2 inside the blade body 1. An arc-shaped plate 4 is slidably arranged in the movable groove 3, and a friction pad 5 is fixedly arranged on the inner side of the arc-shaped plate 4. A screw for installation and connection is inserted into the mounting hole 2, causing the arc-shaped plate 4 to move and squeeze the friction pad 5, so that the friction pad 5 is tightly attached to the surface of the screw. The friction pad 5 increases the friction between the blade body 1 and the screw, making the blade less prone to deflection.

[0017] Preferably, the blade body 1 has a guide groove 6 that communicates with the movable groove 3 inside, and a threaded sleeve 7 is fixedly provided on the outer side of the arc plate 4, and the threaded sleeve 7 is slidably disposed in the guide groove 6.

A knob block 9 is fixedly provided at one end of the slide rod 8, and the knob block 9 is located on the outside of the blade body 1. A threaded rod 10 is fixedly provided at the other end of the slide rod 8, and the threaded rod 10 is used in conjunction with the threaded sleeve 7. By using the knob block 9 to drive the threaded rod 10 to rotate, the threaded rod 10 and the threaded sleeve 7 are used in conjunction. Rotating the knob block 9 can move the arc plate 4, and the arc plate 4 can squeeze the friction pad 5, so that the friction pad 5 is tightly attached to the surface of the screw.

[0019] Preferably, a limiting groove 11 is formed on the inner wall of the blade body 1, and a limiting plate 12 is fixedly provided on the surface of the slide bar 8, and the limiting plate 12 is located in the limiting groove 11. Both the limiting plate 12 and the limiting groove 11 are circular, and the limiting plate 12 can make the knob block 9 and the threaded rod 10 rotate stably.
