Technical Field
[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a protective door suitable for numerically controlled lathes. Background Art
[0002] CNC lathe is a high-precision, high-efficiency automated machine tool. Equipped with a multi-station turret or a power turret, the machine tool has a wide range of processing capabilities and can process linear cylinders, oblique cylinders, arcs, and various threads, grooves, worms and other complex workpieces. It has linear interpolation, circular interpolation and various compensation functions, and has played a good economic effect in the mass production of complex parts.
[0003] A large amount of debris will be generated during the machining process of the CNC lathe. In order to prevent the debris from splashing and causing injuries to the staff, a protective door needs to be installed on the front of the CNC lathe. The traditional protective door has a single function and can only provide simple protection. During long-term use, its inner wall comes into contact with the debris, which can easily cause damage to the inner wall, thereby affecting the service life of the protective door. The debris will automatically fall off after splashing, causing a lot of work for later cleaning. At the same time, some small debris is easy to adhere to the inner wall of the protective door and is difficult to clean. When the debris splashes, it is easy for the protective door to get stuck at the connection between the protective door and the CNC lathe, making it inconvenient to open and close the protective door. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

At the same time, the rubber plate is used to protect the inner wall of the main body when the flying debris splashes, so as to prevent the debris from impacting the inner side of the main body and causing damage to the main body. When the debris is blocked by the main body, it automatically falls into the storage tank due to its own weight, and the collected debris is automatically recovered by the drawer. The debris after rebound is blocked by the inclined plate so that it falls into the storage tank through the inclined plate.
[0018] 2. The utility model realizes that after the CNC machine tool has been working for a period of time, the debris generated by it is easy to accumulate on the inner wall of the blanking chute. At this time, it is only necessary to pull the pulling block, so that the pulling block drives the scraper to scrape the inner wall of the blanking chute, so that the debris inside the blanking chute falls into the storage chute, and at the same time, the scraper drives the slider to drive the movable block to slide on the outer peripheral surface of the connecting rod, thereby maintaining the stability of the scraper when moving and squeezing the spring. After scraping the inner side of the blanking chute, release the pulling block, so that the scraper drives the slider to drive the movable block to loosen. At this time, the pressure on the spring is released and drives the movable block to drive the slider and the scraper to reset, which is convenient for the next use and the automatic cleaning effect of the blanking chute.

[0026] Specifically, the inner wall of the blanking trough 2 is bonded with a rubber sheet, and a group of storage troughs 3 are installed at the bottom, and a ramp 4 is fixedly installed on the side of the blanking trough 2. The advantage is that when the protective door is closed, the inside of the CNC machine tool starts to work, and the debris generated when the CNC machine tool works causes splashing. First, the protective door is used to prevent the debris from flying out and causing accidental injuries to the staff. At the same time, when the flying debris splashes, the rubber sheet is used to protect the inner wall of the main body 1 to prevent the debris from impacting the inside of the main body 1 and causing damage to the main body 1. When the debris is blocked by the main body 1, it automatically falls into the storage trough 3 by its own weight, and the collected debris is automatically recovered by the drawer, and the rebounded debris is blocked by the ramp 4, so that it falls into the storage trough 3 through the ramp 4.
[0027] Specifically, two groups of grooves 6 are arranged opposite to each other, and a connecting rod 7 is fixedly installed inside, a movable block 8 is slidably installed on the outer circumference of the connecting rod 7, and a spring 9 is fixedly installed at the bottom of the movable block 8. The advantage is that the two groups of connecting rods 7 support the two groups of movable blocks 8, the spring 9, the slider 10 and the scraper 11, while maintaining the stability of the scraper 11 when moving.
[0028] Specifically, two sets of sliders 10 are relatively fixedly installed on the left and right sides of the scraper 11, and a pull block 12 is fixedly installed on the side. The advantage is that when the CNC machine tool works for a period of time, the debris generated by it is easy to accumulate on the inner wall of the blanking trough 2. At this time, it is only necessary to pull the pull block 12, so that the pull block 12 drives the scraper 11 to scrape the inner wall of the blanking trough 2, so that the debris inside the blanking trough 2 falls into the storage trough 3. At the same time, the scraper 11 drives the slider 10 to drive the movable block 8 to slide on the outer peripheral surface of the connecting rod 7, so as to maintain the stability of the scraper 11 when moving, and squeeze the spring 9. After scraping the inner side of the blanking trough 2, the pull block 12 is released, so that the scraper 11 drives the slider 10 to drive the movable block 8 to loosen. At this time, the pressure on the spring 9 is released, and the movable block 8 drives the slider 10 and the scraper 11 to reset, which is convenient for the next use, and at the same time, it is convenient for the blanking trough 2 to automatically clean the effect.
[0029] Specifically, the other side of the connection strip 13 is fixedly installed on the edge of the CNC lathe, and a rubber strip 14 is fixedly installed on the side.

This structure shields the connection between the main body 1 and the CNC lathe to prevent debris from entering and causing the protective door to get stuck.
[0030] During use, when the protective door is closed, the CNC machine tool starts to work inside, and the debris generated when the CNC machine tool is working causes splashing. First, the protective door is used to prevent the debris from flying out and causing accidental injuries to the staff. At the same time, when the flying debris splashes, the inner wall of the main body 1 is protected by the rubber plate to prevent the debris from impacting the inner side of the main body 1 and causing damage to the main body 1. When the debris is blocked by the main body 1, it automatically falls into the storage trough 3 due to its own weight, and the collected debris is automatically recovered through the drawer, and the rebounded debris is blocked by the inclined plate 4 so that it falls into the storage trough 3 through the inclined plate 4. After the CNC machine tool has been working for a period of time, the debris generated by it is easy to accumulate on the inner wall of the blanking trough 2. At this time, you only need to pull the pull block 12 to make the pull block 12 drive the scraper 11 to scrape the inner wall of the blanking trough 2. The scraper 11 is moved to move, so that the debris inside the blanking trough 2 falls into the storage trough 3. At the same time, the scraper 11 drives the slider 10 to drive the movable block 8 to slide on the outer peripheral surface of the connecting rod 7, thereby maintaining the stability of the scraper 11 when moving and squeezing the spring 9. After scraping the inner side of the blanking trough 2, the pull block 12 is released, so that the scraper 11 drives the slider 10 to drive the movable block 8 to loosen. At this time, the pressure on the spring 9 is released and drives the movable block 8 to drive the slider 10 and the scraper 11 to reset, which is convenient for the next use and the automatic cleaning effect of the blanking trough 2. When the protective door is closed, its edge coincides with the edge of the CNC lathe, so that one side of the rubber strip 14 is fitted with the main body 1. This structure blocks the connection between the main body 1 and the CNC lathe to prevent debris from entering and causing the protective door to get stuck.
