Description

Technical Field

[0001] The utility model relates to the technical field of protective devices for numerically controlled machine tools, in particular to a protective door for numerically controlled machine tools. Background Art

[0002] CNC machine tools are short for digitally controlled machine tools, which are automated machine tools equipped with a program control system. Existing CNC machine tools are equipped with protective doors to isolate the processing space from the outside environment.

[0003] In the existing protective door, a visual window made of glass is also arranged on the protective door, so that the staff can observe the actual processing situation in the CNC machine tool.

[0004] However, when the CNC machine tool is machining, coolant and metal chips will splash, making the inside of the viewing window dirty. When the dirt reaches a certain level, the staff is required to manually wipe the inside of the viewing window. In the existing protective door, the staff needs to wipe and clean it regularly to remove the dirt on the inside of the viewing window. It does not have a self-cleaning function, which increases the workload of the staff. Utility Model Content

[0005] In view of the above problems, the utility model provides a protective door for a CNC machine tool, the purpose of which is to achieve self-cleaning of the visual window and reduce manual labor.

[0008] Furthermore, the cleaning component is a brush made of rubber, one end of a plurality of brushes is arranged on the rotating roller, and the other end contacts the protective door body.

[0009] Furthermore, the protective door also includes a mounting block, which is welded to the mounting frame, and the roller is rotatably disposed on the mounting frame via a bearing.

[0010] Furthermore, the protective door also includes: a cleaning pipe, installed parallel to the roller and located on the side of the roller away from the protective door body; a plurality of nozzles, arranged on the cleaning pipe along the width direction of the protective door body; and a water pump, used to supply water to the cleaning pipe.

[0011] Furthermore, the protective door also includes: a slide groove, which is opened on the mounting frame; a roller, which is rotatably arranged on the protective door body, and the roller is rotatably installed in the slide groove.

[0012] Furthermore, a handle is provided on the protective door body.

[0013] The beneficial effects of the utility model are as follows: by using the utility model, after the CNC machine tool completes machining of a part once, the worker can drive the roller to rotate when pulling the protective door body to open and close, and clean the visible window twice respectively; the dirt on the inner side of the visible window can be automatically scraped and cleaned to ensure the cleanliness of the visible window, and the worker does not need to wipe the visible window regularly, thereby reducing the amount of manual labor.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 and Figure 2As shown, the embodiment of the present application discloses a protective door for a CNC machine tool, comprising: a mounting frame 1, which is arranged on the CNC machine tool; a protective door body 2, which is slidably arranged on the mounting frame 1; a roller 3, which is rotatably arranged on one side of the protective door body 2 along the width direction of the protective door body 2; a cleaning component 31, which is arranged on the roller 3 and abuts against the protective door body 2; a rack 41, which is arranged on the protective door body 2 along the length direction of the protective door; a gear 42, which is arranged on the roller 3, and the gear 42 and the rack 41 are meshingly installed; the protective door body 2 slides along the length direction, which can drive the rack 41 to drive the gear 42 to rotate, so as to make the cleaning component 31 and the protective door body 2 roll in contact and scrape off the dirt on the visible window 21.

[0019] During specific use, after the CNC machine tool completes the machining of the parts, the staff pulls the protective door body 2 and slides the protective door body 2 along the length direction to open the CNC machine tool; during the sliding of the protective door body 2, the rack 41 will also move; the rack 41 and the gear 42 are meshed and installed, and the movement of the rack 41 drives the gear 42 to rotate, thereby driving the roller 3 to rotate. During the rotation of the roller 3, the cleaning component 31 and the protective door body 2 are driven to roll and contact, and the dirt on the visible window 21 is scraped off; by the same token, when the staff pulls the protective door body 2 to close the CNC machine tool, it will also drive the roller 3 to rotate and clean the visible window 21.

[0020] By using the utility model, after the CNC machine tool completes machining of a part, the worker can drive the roller 3 to rotate when pulling the protective door body 2 to open and close, and clean the visible window 21 twice respectively; the dirt on the inner side of the visible window 21 can be automatically scraped and cleaned to ensure the cleanliness of the visible window 21, and the worker does not need to wipe the visible window 21 regularly, thereby reducing the amount of manual labor.

[0021] Specifically, the cleaning component 31 uses a rubber brush, one end of which is arranged on the roller 3, and the other end is against the protective door body 2. The rubber brush is used to scrape off the coolant and metal chips remaining on the visual window 21, thereby reducing the adhesion of the coolant and metal chips.

[0022] Specifically, the protective door also includes a mounting block 5, which is welded to the mounting frame 1, and the roller 3 is rotatably arranged on the mounting frame 1 through a bearing 51; in actual installation, the outer ring of the bearing 51 is arranged on the mounting block 5, and the outer ring of the bearing 51 is installed on the roller 3.

[0023] Specifically, the protective door also includes: a cleaning pipe 61, which is installed parallel to the roller 3 and is located on the side of the roller 3 away from the protective door body 2; a plurality of nozzles 62, which are arranged on the cleaning pipe 61 along the width direction of the protective door body 2; and a water pump 63, which is used to supply water to the cleaning pipe 61.

[0024] In actual work, water is intermittently supplied to the cleaning pipe 61 through the water pump 63, and water can be sprayed to the cleaning component 31 through the nozzle 62 to regularly flush the coolant and metal chips attached to the cleaning component 31 to ensure the cleanliness of the cleaning component 31 itself and to ensure that the cleaning component 31 can continue to clean the visible window 21.

[0025] Specifically, the protective door also includes: a slide groove, which is opened on the mounting frame 1; a roller 11, which is rotatably arranged on the protective door body 2, and the roller 11 is rollably installed in the slide groove; by setting the roller 11, the wear between the protective door body 2 and the mounting frame 1 is reduced.

[0026] Specifically, a handle 22 is provided on the protective door body 2 , so that the staff can hold the handle 22 and pull the protective door body 2 .
