[0002] A CNC machine tool is an automated machine tool equipped with a program control system. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically processes parts according to the shape and size required by the drawing. When a CNC machine tool is processing parts, the processing tool will generate a lot of noise when cutting parts. If the processing personnel are in a noisy environment for a long time, it will affect their health.

[0003] Existing CNC machine tools generally keep door panels closed during processing to reduce noise. The door panels are hit by flying debris during CNC machine tool processing for a long time and need to be disassembled and repaired regularly. Since the door panels are slidingly connected to the CNC machine tools, bolts are used to prevent the door panels from sliding off the top of the CNC machine tools. This makes it inconvenient to disassemble the door panels from the top of the CNC machine tools. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a CNC machine tool with a noise reduction function, which solves the problem that the existing CNC machine tool and the door panel are slidingly connected, bolts are used to prevent the door panel from sliding off the top of the CNC machine tool, and it is inconvenient to remove the door panel from the top of the CNC machine tool.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a CNC machine tool with a noise reduction function, comprising a CNC machine tool body 1, limit slots 10 are symmetrically arranged at the bottom of both sides of the inner wall of the mounting frame 2, and the top of the CNC machine tool body 1 is located on both sides of the bottom of the mounting frame 2 and the limit strips 11 are symmetrically fixedly installed, and the limit strips 11 correspond to the limit slots 10. By providing the limit slots 10 and the limit strips 11, when the mounting frame 2 is clamped on the top of the CNC machine tool body 1, the limit slots 10 are clamped on the corresponding surface of the limit strips 11 to ensure that the mounting frame 2 will not be misplaced on the top of the CNC machine tool body 1 during installation.

[0022] A mounting frame 2 is provided on one side of the top of the CNC machine tool body 1, and limit slide bars 3 are fixedly installed on the top and bottom of both sides of the mounting frame 2, and a noise reduction plate 4 is slidably installed on the surface between the two groups of limit slide bars 3 on the same side of the mounting frame 2. Because the limit slide bar 3 is provided, when the noise reduction plate 4 is controlled to slide on the surface of the limit slide bar 3, it is ensured that the noise reduction plate 4 will not tilt or deflect during the movement.

[0023] The top and bottom ends of the noise reduction plates 4 away from the limiting slide bar 3 are respectively inlaid with movable rollers 5 for rotation, and a connecting plate 6 is fixedly installed between the tops of the two groups of noise reduction plates 4 close to the limiting slide bar 3. By providing the movable rollers 5, when the noise reduction plates 4 move on both sides of the mounting frame 2, the movable rollers 5 roll between the noise reduction plates 4 and the mounting frame 2, thereby reducing the friction of the noise reduction plates 4 when they move on both sides of the mounting frame 2.

[0024] Two groups of support plates 7 are fixedly installed on one side of the top of the mounting frame 2, a conveying screw 8 is rotatably installed between the two groups of support plates 7, and the connecting plate 6 is rotatably connected to the conveying screw 8. A conveying motor 9 is fixedly installed at the central position of the top of the mounting frame 2, and the end of the conveying screw 8 close to the conveying motor 9 passes through the support plate 7 and is fixedly connected to the conveying motor 9. Because the conveying motor 9 and the conveying screw 8 are provided, the conveying motor 9 is controlled to rotate forward and reverse, so that the conveying screw 8 can control the connecting plate 6 to drive the noise reduction plate 4 to move back and forth on both sides of the mounting frame 2.

[0025] A mounting plate 12 is fixedly installed at the bottom of the CNC machine tool body 1 located on one side of the mounting frame 2, a rectangular groove 13 is provided at the central position of the top of the mounting plate 12, and three groups of mounting slide grooves 14 are equidistantly provided at the bottom of the rectangular groove 13, and a limit plate 15 is slidably installed inside the mounting slide groove 14. By providing the mounting slide groove 14, the fixed card plate 17 is pressed to make the clamping rod 16 press the limit plate 15 to slide up and down inside the mounting slide groove 14, thereby limiting the moving distance of the fixed card plate 17 inside the rectangular groove 13;

[0026] A clamping rod 16 is fixedly installed on the top of the limiting plate 15, and the top of the clamping rod 16 passes through the installation slide groove 14 and extends to the inside of the rectangular groove 13. A fixed clamping plate 17 is fixedly installed on the top of the three groups of clamping rods 16 located inside the rectangular groove 13. The top of the fixed clamping plate 17 is a sloped surface, and a clamping spring 18 is provided on the surface of the clamping rod 16 located inside the rectangular groove 13. Because the fixed clamping plate 17 and the clamping spring 18 are provided, the fixed clamping plate 17 is pushed out of the rectangular groove 13 and clamped at the bottom of one side of the mounting frame 2 under the rebound action of the clamping spring 18, thereby clamping and fixing the mounting frame 2.

[0027] Limiting grooves 19 are symmetrically provided on both sides of the inner wall of the rectangular groove 13, and limiting protrusions 20 are symmetrically fixedly installed on the bottom of both sides of the fixed card plate 17, and the limiting protrusions 20 correspond to the limiting grooves 19. By providing the limiting grooves 19 and the limiting protrusions 20, when the fixed card plate 17 is pressed to move up and down inside the rectangular groove 13, the limiting protrusions 20 slide inside the limiting grooves 19, ensuring that the fixed card plate 17 will not tilt and get stuck inside the rectangular groove 13 when moving up and down inside the rectangular groove 13.

[0028] The working principle of the utility model is:

[0029] The mounting frame 2 is placed on one side of the top of the CNC machine tool body 1, so that the limit slot 10 corresponds to the limit insert 11, and the mounting frame 2 is pushed to move on the top of the CNC machine tool body 1 until the limit insert 11 is completely inserted into the limit slot 10, so that the mounting frame 2 slides through the fixed card plate 17, and under the rebound action of the clamping spring 18, the fixed card plate 17 is lifted up and extended out of the rectangular groove 13 to be clamped on one side of the mounting frame 2. Before the CNC machine tool body 1 is processed, the transmission motor 9 is started to drive the transmission screw 8 to rotate, and the connecting plate 6 is controlled to move on the surface of the transmission screw 8, driving the two sets of noise reduction plates 4 to slide on both sides of the mounting frame 2 until the noise reduction plates 4 are closed on both sides of the mounting frame 2, so as to reduce the noise generated during the processing of the CNC machine tool body 1.
