[0002] A CNC machine tool is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and represent them in coded numbers. The information is input into the CNC device through the information carrier, and the CNC device sends various control signals after calculation and processing to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] When a CNC machine tool is processing a workpiece, in order to avoid causing harm to workers, a protective door on the front of the CNC machine tool is required to separate the workpiece from personnel. According to a publicly disclosed CNC machine tool with a protective structure (Announcement No.: CN218658061U), the above application uses a protective door to separate the workpiece from personnel, but when cleaning the transparent window on the surface of the protective door, it is necessary to clean it manually, and it can only be cleaned after the workpiece is processed. This method will still cause waste chips to splash when the personnel use the transparent window to observe the workpiece, thereby affecting the processing of the workpiece. To address this problem, we have proposed a CNC machine tool with a protective structure. Utility Model Content

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a CNC machine tool with a protective structure, including a machine body 2, the machine body 2 is fixedly mounted on the inner wall of a protective seat 1, the protective seat 1 is hinged with a protective door 3, an observation window 4 is opened on the surface of the protective door 3, a fixed column 5 is fixedly mounted on the inner wall of the protective door 3, an L-shaped rod 7 is fixedly mounted on the surface of the fixed column 5, a control component 6 is arranged in the fixed column 5, and the control component 6 includes: a round rod 61, a vertical plate 62, a gear 63, a round plate 64, a knock block 65, a torsion spring 66, a fixed tooth 67, a cleaning piece 68,

[0024] The round rod 61 passes through the vertical plate 62 and is rotatably connected with the vertical plate 62. The surface of the vertical plate 62 is rotatably connected with the gear 63. The gear 63 meshes with the fixed tooth 67. The gear 63 is fixedly connected with the surface of the round rod 61. The round rod 61 passes through the circular plate 64 and is fixedly connected with the circular plate 64. The knocking block 65 is hinged with the circular plate 64. The surface of the circular plate 64 is fixedly connected with one side of the torsion spring 66. The other side of the torsion spring 66 is fixedly installed on the surface of the knocking block 65. A cleaning piece 68 for cleaning is provided in the fixed column 5. The knocking block 65 hinged on the surface of the circular plate 64 can continuously knock on the surfaces of the connecting plate 684 and the brush plate 685 during the rotation process. Then, the waste chips stuck on the surface of the brush plate 685 can fall off due to the vibration force and fall into the recovery frame 687 for centralized collection. This method can prevent the waste chips from sticking to the observation window 4 again when the brush plate 685 cleans the observation window 4, thereby affecting the observation line of the personnel.

[0025] The cleaning member 68 comprises a slide bar 681, the surface of which is fixedly connected to the surface of the fixed tooth 67. When the slide bar 681 moves, the fixed tooth 67 can slide on the surface of the gear 63. A slider 682 is fixedly installed on the surface of the slide bar 681. The slider 682 penetrates the vertical plate 62 and is slidably connected to the vertical plate 62. The inner wall of the vertical plate 62 is fixedly connected to one end of a spring 683. The other end of the spring 683 is fixedly installed on the surface of the slider 682. When the slide bar 681 is resisted, the slider 682 can slide in the vertical plate 62 under the support of the spring 683. A connecting plate 684 is fixedly installed on the surface of the vertical plate 62. A brush plate 685 is fixedly installed on the surface of the connecting plate 684. When the connecting plate 684 moves, the brush plate 685 can move synchronously. A slide rail 686 is provided on the inner wall of the connecting plate 684. The slide rail 686 is slidably connected to the recovery frame 687. The recovery frame 687 can slide on the surface of the slide rail 686. A moving block 688 is fixedly installed at the bottom of the connecting plate 684. The moving block 688 is penetrated by a threaded rod 689 and is threadedly connected to the threaded rod 689. The threaded rod 689 penetrates the fixed column 5 and is rotatably connected to the fixed column 5. A motor 680 is fixedly installed on the surface of the fixed column 5. The output shaft of the motor 680 is fixedly connected to the surface of the threaded rod 689. When the threaded rod 689 rotates, the moving block 688 is forced to slide laterally in the fixed column 5.

[0026] In the utility model, when in use, the protective door 3 is opened, the workpiece to be processed is placed on the surface of the machine tool body 2, and the workpiece is fixed on the surface of the machine tool body 2. After fixing, the protective door 3 is closed, and the machine tool body 2 is started to process the workpiece. During the processing, the operator observes the workpiece through the observation window 4. When waste chips are stuck on the surface of the observation window 4, the motor 680 on the surface of the fixed column 5 is started, and the output shaft of the motor 680 drives the threaded rod 689 to perform a circular motion in the fixed column 5. When the threaded rod 689 rotates, the moving block 688 is forced to move, and the connecting plate 684 fixed on the surface of the moving block 688 drives the brush plate 685 to slide synchronously to scrape off the waste chips stuck on the surface of the observation window 4. When the brush plate 685 moves to the observation window 4, the L-shaped rod 7 will contact the cross section of the slide bar 681. After the cross section of the slide bar 681 is abutted, the slide bar 681 is forced to move, and the fixed tooth 67 fixed on the surface of the slide bar 681 slides on the surface of the gear 63. The gear 63 is forced to drive the round rod 61 to rotate on the surface of the vertical plate 62, and the circular plate 64 fixed on the surface of the round rod 61 rotates synchronously. The knocking block 65 hinged on the surface of the circular plate 64 can continuously knock on the surfaces of the connecting plate 684 and the brush plate 685 during the rotation. The waste chips stuck on the surface of the brush plate 685 can fall off due to the vibration force and fall into the recovery frame 687 for centralized collection. This method can prevent the waste chips from sticking to the observation window 4 again when the brush plate 685 is cleaning the observation window 4, thereby affecting the observation line of the personnel.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
