Description

Technical Field

[0001] The utility model relates to the technical field of protective covers, in particular to a machine tool protective cover. Background Art

[0002] As a key functional component of machine tools, machine tool guards provide safety, precision, and environmental protection, and are increasingly valued by machine tool manufacturers and users. Typically, a door is installed on the front of a machine tool guard to facilitate frontal observation and access to components.

[0003] Machine tool protective covers are used to provide protection during the machining process. During the machining process, metal dust particles are generated, which will adhere to the surface of the observation window on the protective cover. Therefore, the observation window of the machine tool protective cover needs to be cleaned. However, after cleaning, the cleaned water source will contain a large amount of metal particles. Therefore, the sewage needs to be filtered and cleaned to prevent the sewage from polluting the water source and the environment.

[0004] For example, a Chinese patent (publication number: CN214922682U) discloses a machine tool protective cover, which includes a protective cover and a cleaning mechanism for cleaning the protective cover. During use, the above patent can only perform simple cleaning of the protective cover, and does not filter the cleaned sewage, thus easily causing water pollution and geological pollution. Summary of the Invention

Moreover, since the pore size of the RO membrane is one millionth of a hair (0.0001 micron), it is generally invisible to the naked eye. Therefore, during the filtration process, metal particles inside the sewage cannot pass through the RO membrane, thereby ensuring the filtration effect. In addition, the filtered water source can be reused, avoiding pollution and saving water resources, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a machine tool protective cover, comprising a protective door, wherein an observation window is provided at the center of the front end surface of the protective door;

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 2 、 Figure 5 As shown, the utility model provides a technical solution:

[0034] A machine tool protective cover comprises a protective door 1, wherein an observation window 11 is provided at the center position of the front end face of the protective door 1; a cleaning piece 57 is provided at the front end of the observation window 11, and a water tank 12 is fixedly installed on the front end face of the protective door 1 below the observation window 11; a filter assembly 8 is provided at the lower right end of the protective door 1, and the filter assembly 8 comprises a recovery cylinder 81 fixedly installed at the lower right end of the protective door 1; an RO membrane cylinder 84 is installed inside the recovery cylinder 81, and an extrusion piece 88 is slidably installed inside the recovery cylinder 81 at the upper end of the RO membrane cylinder 84, and a partition plate 9 is fixedly installed on the upper end of the interior of the recovery cylinder 81, and a U-shaped rod 86 is provided between the partition plate 9 and the RO membrane cylinder 84, and the upper end of the extrusion piece 88 passes through the two ends of the opening of the U-shaped rod 86 and the upper end passes through the partition plate 9.

[0035] The inner wall of the recovery cylinder 81 is located between the partition plate 9 and the RO membrane cylinder 84, and a first motor 85 is fixedly installed. The end of the first motor 85 away from the recovery cylinder 81 is fixedly installed on the middle part of the U-shaped rod 86. A groove disk 87 is eccentrically fixedly installed on the output shaft of the first motor 85 on the inner side of the U-shaped rod 86. The cylinder in the middle of the right side of the extrusion member 88 extends to the inside of the groove disk 87. An opening and closing cover 82 is rotatably installed on the circumferential surface of the recovery cylinder 81. Two mounting grooves 83 are provided on the inner circumferential surface of the recovery cylinder 81. The upper and lower ends of the RO membrane cylinder 84 are respectively slidably installed in the adjacent mounting grooves 83. The upper end of the recovery cylinder 81 is fixedly installed with a suction pump 7, and the upper end of the suction pump 7 is fixedly installed with a recovery pipe 6. The other end of the recovery pipe 6 is fixedly installed at the lower right end of the water tank 12 and passes through the water tank 12.

[0036] By adopting the above technical solution, when in use, first, the cleaned sewage will enter the interior of the water tank 12, and the sewage inside the water tank 12 will enter the interior of the recovery cylinder 81 under the action of the suction pump 7. It should be noted that the lower end of the material pipe connecting the suction pump 7 and the recovery cylinder 81 is located below the partition plate 9. Therefore, the sewage can enter the interior of the recovery cylinder 81, and the sewage entering the interior of the recovery cylinder 81 will then enter the interior of the RO membrane cylinder 84. Then, the first motor 85 is started under the action of the controller, and the output shaft of the first motor 85 will rotate synchronously with the groove disk 87. Since the output shaft of the first motor 85 and the groove disk 87 are eccentrically arranged, the groove disk 87 will drive the extrusion member 88 to move up and down linearly under the restriction of the U-shaped rod 86 during use, and then the extrusion member 88 can squeeze the RO membrane inside the RO membrane cylinder 84, so that the sewage can pass through the RO membrane, and then the filtered water source will enter the water tank 2 again through the pipeline; under the action of the above structure, the metal particles inside the sewage can be separated from the water source, so that the water source can be reused, and secondly, the water source will not be polluted.

[0037] Specifically, such as Figure 1 、 Figure 3 As shown, a water tank 2 is fixedly installed at the lower end of the protective door 1, and a feeding pump 3 is fixedly installed at the left end of the water tank 2 at the lower end of the protective door 1. A connecting pipe is fixedly installed between the feeding pump 3 and the water tank 2, and a water pipe 31 is fixedly installed at one end of the feeding pump 3 away from the water tank 2. The other end of the water pipe 31 is located above the observation window 11, and spray holes are evenly arranged on the circumferential surface of one end of the water pipe 31 located at the observation window 11. A servo motor 4 is fixedly installed on the front end face of the protective door 1 located on the left side of the observation window 11, and a lifting rod 41 is fixedly installed on the output shaft of the servo motor 4. The lower end of the lifting rod 41 is rotatably installed on the left end of the slot 12.

[0038] A cross bar groove 51 is rotatably installed on the circumferential surface of the lifting rod 41, and the right end of the cross bar groove 51 is slidably installed on the front right part of the protective door 1. An adjusting motor 52 is fixedly installed on the left side of the rear end surface of the cross bar groove 51, and a forward and reverse screw 53 is fixedly installed on the output shaft of the adjusting motor 52. Two slides 54 are slidably installed on the circumferential surface of the forward and reverse screw 53, and a connecting rod 55 is rotatably installed at the rear end of the two slides 54. A mounting plate 56 is provided behind the adjacent ends of the two connecting rods 55, and the adjacent ends of the two connecting rods 55 are rotatably installed on the front end surface of the mounting plate 56, and the cleaning piece 57 is slidably installed on the inner side of the mounting plate 56.

[0039] By adopting the above technical solution, when in use, the water source inside the water tank 2 can be used to clean the observation window 11 under the action of the feeding pump 3. During the cleaning process, water stains will remain on the surface of the observation window 11, so the observation window 11 needs to be cleaned a second time; then, the adjusting motor 52 is started, and the output shaft of the adjusting motor 52 will drive the forward and reverse screws 53 to rotate, so that the two slides 54 on the circumferential surfaces of the forward and reverse screws 53 can approach or move away, and then the connecting rod 55 can push the mounting plate 56 close to the protective door 1, so that the mounting plate 56 can drive the cleaning piece 57 close to the protective door 1, so that the cleaning piece 57 can fit with the front end surface of the protective door 1, and then the servo motor 4 is started, and the output shaft of the servo motor 4 drives the lifting rod 41 to rotate, so that the cross bar slot 51 can move up and down, Thereby, the cleaning member 57 can clean the observation window 11, and in order to ensure the drying of the cleaning member 57 after cleaning, the adjusting motor 52 is started, so that the connecting rod 55 pushes the mounting plate 56 with the cleaning member 57 to fit tightly with the protective door 1, so that the sewage inside the cleaning member 57 is squeezed out and flows into the inside of the water tank 12. Moreover, since there are slide grooves at the upper and lower ends of the inner side of the mounting plate 56, the cleaning member 57 can be replaced during use to ensure that the cleaning member 57 is clean; with the cooperation of the above-mentioned multiple structures, the sewage contained in the cleaning member 57 can flow out, ensuring the drying of the cleaning member 57, and the sewage will not be thrown out like a roller during use. Secondly, the cleaning member 57 can be replaced during use.

[0040] Working principle: First, under the action of the feeding pump 3, the water inside the water tank 2 is sprayed out through the spray holes on the circumferential surface of the water pipe 31 to clean the observation window 11. Then, under the action of the servo motor 4 and the lifting rod 41, the cleaning part 57 wipes and cleans the observation window 11.

[0041] Then, under the action of the regulating motor 52 , the cleaning member 57 can squeeze out the sewage contained therein, so that the sewage enters the interior of the water tank 12 .

[0042] Secondly, under the action of the suction pump 7, the sewage enters the interior of the recovery cylinder 81, and then is filtered under the action of the extruder 88 and the RO membrane cylinder 84. The filtered water source will enter the interior of the water tank 2 again. During use, the operator can replace the cleaning part 57 and the RO membrane cylinder 84 to ensure the cleaning effect of the filtration.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
