Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-5 The CNC machine tool for processing hardware parts shown includes a CNC machine tool body 1, a fixed frame 2 fixedly connected to the CNC machine tool body 1, and a processing table arranged inside the fixed frame 2.

[0026] Furthermore, the fixed frame 2 is internally equipped with a protective mechanism 3 for shielding metal processing debris. The protective mechanism 3 includes a protective frame 31, which is U-shaped and slides from the back of the CNC machine tool body 1. The protective frame 31 helps to protect the metal processing debris from splashing and prevents the debris from scattering everywhere. The protective frame 31 is located on the CNC machine tool body 1. A protective door 32 is rotatably connected to the front of the protective frame 31. The protective frame 31 and the protective door 32 are used to enclose the processing table to shield the metal processing debris. The fixed frame 33 also includes a mounting frame 33, an assembly plate 34, and a support plate 35. The mounting frame 33 is conveniently connected to the assembly plate 34 to support the installation position of the protective frame 31. The mounting frame 33 is located on the fixed frame 1. On the mounting frame 2, the assembly plate 34 and the bearing plate 35 are located on the side of the protective frame 31.

The inner cavity of the protective frame 31 is fitted with a receiving plate 36. The side of the receiving plate 36 has a through groove and a first sliding groove symmetrically formed on the side of the receiving plate 36. Positioning posts 314 are symmetrically fixedly connected to the main body 1 of the CNC machine tool. The positioning posts 314 facilitate sliding connection with the receiving plate 36, thereby facilitating the sliding installation of the protective frame 31. The positioning posts 314 are slidably inserted into the inner cavity of the first sliding groove. The top of the receiving plate 36 is symmetrically fixedly connected with a positioning frame 37. The positioning frame 37 facilitates the sliding of the positioning plate 38 within it, providing sliding support for the positioning plate 38. The positioning frame 37 has a slidable positioning plate 38 inside, which helps to limit the relative position of the positioning frame 37 and the positioning post 314, thereby limiting the position of the protective frame 31 and facilitating its installation and disassembly, preventing the protective frame 31 from sliding arbitrarily.

A second sliding groove is provided at the top of the inner wall of the positioning frame 37, and a connecting frame 310 is fixedly connected to the top of the inner wall of the second sliding groove. The connecting frame 310 is U-shaped. The sliding rod 311 is guided by a spring 313, which also facilitates the compression of the spring 313. The sliding rod 311 is fixedly connected to the side of the inner wall of the moving frame 39, which helps to move the moving frame 39. The sliding rod 311 is slidably inserted into the inner cavity of the connecting frame 310. One end of the sliding rod 311 is fixedly connected to a moving plate 312, which facilitates the movement of the sliding rod 311, and thus the movement of the moving frame 39 and the positioning plate 38. A spring 313 is sleeved on the outer wall of the sliding rod 311 to drive the moving plate 312 to slide horizontally. The elastic force of the spring 313 helps to push the moving plate 312 to move, facilitating the return of the moving plate 312 and the sliding rod 311 to their original positions after movement, and facilitating repeated operation of the positioning plate 38.One end of spring 313 is fixedly connected to connecting bracket 310, and the other end of spring 313 is fixedly connected to movable plate 312.
