Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machine tool protective device. Background Technology

[0002] CNC machine tools generate a lot of debris during the machining process, which can easily cause injury to workers. Therefore, protective devices are needed to cover the entire CNC machine tool during operation to prevent debris from flying around.

[0003] A search revealed that Chinese Patent Publication No. CN211760204U discloses a protective device for CNC machine tools. Its basic description is as follows: by setting a rectangular block and a screw, the rectangular block is inserted into a protrusion on the top of the machine tool, and by rotating the screw, the screw is inserted into a slot on the machine tool, thereby fixing the protective device. This fixing method is very convenient, reduces the wear of the protective device, and improves the practicality of the device.

[0004] Existing protective devices are prone to chipping and splashing during processing, causing the chips to adhere to the surface of the pull plate, making it difficult to move the pull plate and thus reducing the effectiveness of the device. Utility Model Content

[0016] Beneficial effects:

[0017] 1. This CNC machine tool protective device, by activating the push rod motor, causes the moving column to move inward along the connecting frame, and then moves inward through the cleaning strip to clean the inside of the transparent frame. This makes it easier for the operator to operate the components inside the device to clean up debris, preventing the splashed debris from sticking to the components inside the device, reducing the impact of debris sticking to the surface of the components on the operator's normal observation, and further enhancing the effectiveness of the components inside the device during operation.

This further improves the stability of the components during use, reduces the impact of loose components on the normal operation of the device, and makes it easier for operators to manipulate the components to fix the device.

[0022] 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.

[0023] Please see Figure 1-2 This utility model provides a technical solution: a CNC machine tool protective device, including a connecting frame 1, a connecting strip 2 inside the connecting frame 1, and a push rod motor 7 (model LAP22) installed inside the connecting frame 1. Activating the push rod motor 7 causes the moving column 8 to move inward along the connecting frame 1, and then inward via the cleaning strip 14 to clean the inside of the transparent frame 5. This makes it easier for operators to manipulate the components inside the device to clean debris, preventing sputtered debris from adhering to the components and reducing surface adhesion of the components. The impact of debris on the operator's normal observation further enhances the effectiveness of the components in the working process. The moving column 8 is slidably connected inside the connecting frame 1. The output end of the push rod motor 7 is installed on the outer side of the moving column 8. A buffer spring 9 is installed on the inner side of the moving column 8. A buffer plate 10 is installed on the inner end of the buffer spring 9. A connecting block 11 is installed on the upper surface of the moving column 8. A baffle plate 12 is installed on the upper surface of the connecting block 11. A connecting plate 13 is installed on the front of the moving column 8. A cleaning strip 14 is installed on the front of the connecting plate 13.

[0024] In this invention, to ensure greater stability of the internal components during use, a fixing plate 3 is installed on the front of the connecting strip 2. A fixing pin 4 passes through the front of the fixing plate 3. By manipulating the fixing pin 4 through the fixing plate 3 and inserting it into the connecting frame 1, and then rotating the fixing pin 4 clockwise, the fixing plate 3 is secured. This makes the internal components of the device more stable during use, preventing loosening and further improving the stability of the components. It also reduces the impact of loosening on the normal operation of the device and makes it easier to operate. Personnel operate the components to fix the device. One end of the fixing pin 4 passes through the fixing plate 3 and enters the connecting frame 1. The upper and lower sides of the front of the fixing plate 3 are provided with circular connecting holes. The size of the circular connecting holes is adapted to the size of the fixing pin 4. The front of the connecting frame 1 is provided with a square connecting groove. The connecting strip 2 is a square sliding plate. The connecting strip 2 is slidably connected to the connecting frame 1. The front of the connecting frame 1 is provided with a threaded hole. The outer surface of the fixing pin 4 is provided with external threads. The fixing pin 4 is threadedly connected to the connecting frame 1. A transparent frame 5 is installed on the inner side of the fixing plate 3. The lower surface of the connecting frame 1 is fixedly connected with a discharge plate 6 to prevent the components from becoming loose.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use, move the transparent frame 5 to the front of the connecting frame 1, manipulate the fixing plate 3 to slide the connecting strip 2 along the connecting frame 1, manipulate the fixing pin 4 to pass through the fixing plate 3 and insert it into the connecting frame 1, then rotate the fixing pin 4 clockwise to fix the fixing plate 3. When the debris splashes onto the surface of the transparent frame 5, start the push rod motor 7. The output end of the push rod motor 7 moves inward, driving the moving column 8 to move inward. The moving column 8 moves inward along the connecting frame 1. The moving column 8 moves inward, driving the buffer spring 9 to move inward. The buffer spring 9 moves inward, driving the buffer plate 10 to move inward. The moving column 8 moves inward, driving the connecting block 11 to move inward. The connecting block 11 moves inward, driving the shielding plate 12 to move inward. The moving column 8 moves inward, driving the connecting plate 13 to move inward. The connecting plate 13 moves inward, driving the cleaning strip 14 to move inward. The cleaning strip 14 moves inward to clean the inside of the transparent frame 5, so that the debris is discharged along the discharge plate 6.

[0027] In summary, this CNC machine tool protective device, by activating the push rod motor 7, causes the moving column 8 to move inward along the connecting frame 1, and then moves inward via the cleaning strip 14 to clean the inside of the transparent frame 5. This makes it easier for operators to manipulate the components inside the device to clean up debris, preventing the splashed debris from sticking to the components inside the device, reducing the impact of debris sticking to the surface of the components on the operator's normal observation, and further enhancing the effectiveness of the components inside the device during operation.

[0028] This CNC machine tool protective device uses a fixed pin 4 to pass through the fixed plate 3 and insert into the connecting frame 1. Then, the fixed pin 4 is rotated clockwise to fix the fixed plate 3. This makes the components inside the device more stable during use, thereby preventing the components from becoming loose. This further improves the stability of the components during use, reduces the impact of loose components on the normal use of the device, and makes it easier for operators to manipulate the components to fix the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
