[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: an automatic spindle feed mechanism for an adaptive electric drive drilling machine, including a spindle assembly 1, a motor 2 mounted on the surface of the spindle assembly 1, and a sealing device 3 on the surface of the spindle assembly 1 to achieve dust prevention, avoiding the situation where dust or debris enters the spindle assembly 1, causing increased friction between the spindle assemblies and reducing the service life of the spindle assembly 1, thus improving the practicality of the device. A shock-absorbing device 4 is provided on the surface of the spindle assembly 1 to achieve shock absorption of the motor 2, avoiding the situation where the motor 2 shakes due to external factors, causing fluctuations in the feed rate, thus improving the practicality of the device.

[0024] The specific settings and functions of its sealing device 3 and shock absorption device 4 will be explained below.

[0025] Reference Figure 2 and Figure 3As shown, in this embodiment: the sealing device 3 includes a sealing ring 301, which is slidably connected to the surface of the spindle assembly 1. A pressure plate 302 is slidably connected to the surface of the sealing ring 301, and the pressure plate 302 is slidably connected to the surface of the spindle assembly 1. Short rods 303 are fixedly connected to both sides of the spindle assembly 1. Long plates 305 are slidably connected to the arc surfaces of the two short rods 303. A fixing rod 306 is slidably inserted into the long plate 305. A circular plate 308 is fixedly connected to one end of the fixing rod 306. A fixing hole 309 is opened on the arc surface of the pressure plate 302. A first spring 307 is sleeved on the arc surface of the fixing rod 306. The two ends of the spring 307 are fixedly connected to the circular plate 308 and the long plate 305, respectively. When the circular plate 308 is released, the first spring 307 drives the circular plate 308, which in turn drives the fixing rod 306 to slide within the long plate 305 until the fixing rod 306 is inserted into the fixing hole 309. This achieves a stable connection of the fixing rod 306, preventing the fixing rod 306 from shaking due to the shaking caused by the spindle assembly 1 during use. The short rod 303 has a rotating ring 304 rotatably connected to its arc surface. The surface of the rotating ring 304 is fixedly connected to the long plate 305. The surface of the spindle assembly 1 has an opening... The recycling trough 310 is used to pull the fixing rod 306 out of the fixing hole 309. Then, the rotating ring 304 is rotated, causing the long plate 305 to rotate on the arc surface of the short rod 303. The long plate 305 drives the fixing rod 306, which in turn drives the circular plate 308 until the fixing rod 306 is perpendicular to the recycling trough 310. Then, the circular plate 308 is pushed to make the fixing rod 306 slide within the long plate 305 until the fixing rod 306 is inserted into the recycling trough 310. This achieves the effect of rotating and recycling the fixing rod 306, avoiding shaking caused by external factors that would cause the fixing rod 306 to slide back and forth within the long plate 305. This leads to a situation where workers need to continuously pull the fixing rod 306 to replace the sealing ring 301. The surface of the spindle assembly 1 is fixedly connected to the positioning plate 311. The size of the fixing rod 306 is adapted to the size of the fixing hole 309. Rotating the rotating ring 304 causes the long plate 305 to rotate on the arc surface of the short rod 303. The long plate 305 drives the fixing rod 306, and the fixing rod 306 drives the circular plate 308 until the fixing rod 306 touches the positioning plate 311, thus achieving the effect of positioning the fixing rod 306, so as to quickly replace the sealing ring 301 and put the spindle assembly 1 into use more quickly.

[0026] Reference Figure 4 and Figure 5As shown, specifically, the shock absorption device 4 includes a support plate 41, which is fixedly connected to the surface of the main shaft assembly 1. A sliding column 42 is fixedly connected to the surface of the support plate 41, and a connecting plate 44 is slidably connected to the arc surface of the sliding column 42. The surface of the connecting plate 44 is fixedly connected to the motor 2. A second spring 43 is sleeved on the arc surface of the sliding column 42, and both ends of the second spring 43 are fixedly connected to the connecting plate 44 and the support plate 41, respectively. A fixing cover 45 is fixedly connected to one end of the sliding column 42, and a connecting frame 46 is fixedly connected to the surface of the fixing cover 45. A limiting rod 47 is slidably inserted into the connecting frame 46. A limiting groove is formed on the surface of the connecting plate 44. When it is necessary to repair the motor 2, the limiting rod 47 is pushed to the connecting plate 44. The motor 2 slides within the frame 46 until the limiting rod 47 inserts into the limiting groove of the connecting plate 44, thus fixing the motor 2 in place. This prevents the motor 2 from moving when maintenance is needed, allowing for more stable maintenance by the staff. A baffle 48 is fixedly connected to the arc surface of the limiting rod 47. The size of the limiting rod 47 matches the size of the limiting groove on the surface of the connecting plate 44. Pulling the limiting rod 47 causes the baffle 48 to slide within the connecting frame 46 until the baffle 48 touches the connecting frame 46, thus blocking the limiting rod 47 and preventing it from slipping out of the connecting frame 46 due to external factors, which could cause damage to the limiting rod 47.

[0027] Working principle: When the sealing ring 301 needs to be replaced, rotate the rotating ring 304. The rotating ring 304 drives the long plate 305 to rotate on the arc surface of the short rod 303. The long plate 305 drives the fixed rod 306, and the fixed rod 306 drives the circular plate 308 until the fixed rod 306 touches the positioning plate 311. Then push the circular plate 308 to drive the fixed rod 306 to slide inside the long plate 305 until the fixed rod 306 is inserted into the recycling groove 310. Remove the pressure plate 302 and the sealing ring 301. After the replacement is completed, pull the fixed rod 306 out of the recycling groove 310. Then rotate the rotating ring 304. The rotating ring 304 drives the long plate 305 to rotate on the arc surface of the short rod 303. 5. The short rod 303 rotates on its arc surface, the long plate 305 drives the fixed rod 306, the fixed rod 306 drives the circular plate 308 until the fixed rod 306 is perpendicular to the fixed hole 309. The circular plate 308 is then released, the first spring 307 drives the circular plate 308, and the circular plate 308 drives the fixed rod 306 to slide within the long plate 305 until the fixed rod 306 is inserted into the fixed hole 309. This achieves the effect of dustproofing the spindle assembly 1, avoiding the situation where dust or debris enters the spindle assembly 1, which would increase the friction between the spindle assemblies 1 and reduce the service life of the spindle assembly 1, thus improving the practicality of the device.

[0028] When motor 2 vibrates, it drives connecting plate 44 to slide on the arc surface of sliding column 42. Connecting plate 44 compresses second spring 43, and the rebound force of second spring 43 counteracts the force generated by the vibration. When motor 2 needs to be repaired, limit rod 47 is pushed to slide in connecting frame 46 until limit rod 47 is inserted into the limit groove of connecting plate 44. After completion, limit rod 47 is pulled, and limit rod 47 drives baffle 48 to slide in connecting frame 46 until baffle 48 touches connecting frame 46. This achieves the effect of vibration reduction for motor 2, avoiding vibration caused by external factors, which would cause motor 2 to vibrate and thus cause fluctuations in feed rate, improving the practicality of the device.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
