Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0022] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a precision mechanical hole-opening device for CNC lathe machining, including a base 1, a support seat 2 fixedly connected to the bottom of the base 1, a hole-opening mechanism 5 fixedly connected to the top of the base 1, an angle adjustment mechanism 4 rotatably connected inside the base 1, the angle adjustment mechanism 4 including a first rotating ball block 41, the first rotating ball block 41 rotatably connected inside the base 1, a fixing mechanism 3 fixedly connected to the top of the first rotating ball block 41, and a vibration collection mechanism 6 fixedly connected inside the base 1; Angle adjustment mechanism 4 includes; The third telescopic motor 46 is fixedly connected to the bottom of the base 1. The second rotating ball block connecting block 48 is fixedly connected inside the third telescopic motor 46 through the output shaft. The second rotating ball block 45 is rotatably connected inside the second rotating ball block connecting block 48, and the surface of the second rotating ball block 45 is rotatably connected to the first rotating ball connecting block 44.

[0023] The fixing mechanism 3 includes a second fixing block 38, which is fixedly connected to the top of the first rotating ball block 41. A drilling platform 32 is fixedly connected to the top of the second fixing block 38, and a first fixing block 33 is fixedly connected to the surface of the drilling platform 32.

[0024] A first telescopic motor 31 is fixedly connected to the surface of the first fixed block 33. A first limiting block 34 is fixedly connected to the inside of the first telescopic motor 31 through an output shaft. A first motor 35 is fixedly connected to the surface of the first limiting block 34. A first lead screw 37 is rotatably connected to the inside of the first motor 35. A second limiting block 36 is slidably connected to the surface of the first lead screw 37, and the second limiting block 36 is slidably connected to the inside of the first limiting block 34.

[0025] The angle adjustment mechanism 4 also includes a tilt sensor 47, which is fixedly connected to the bottom of the drilling platform 32. A second telescopic motor 43 is fixedly connected to the bottom of the base 1, and a locking arc block 42 is fixedly connected inside the second telescopic motor 43 through its output shaft.

[0026] In use, the workpiece is first placed on top of the drilling platform 32. Then, the first telescopic motor 31 is started. The start of the first telescopic motor 31 drives the first limit block 34 through the output shaft to fix the workpiece. Then, the first motor 35 is started. The start of the first motor 35 drives the first lead screw 37 to rotate through the output shaft. The rotation of the first lead screw 37 further fixes the workpiece. Then, a third telescopic motor 46 is started. The start of the third telescopic motor 46 drives the second rotating ball block connecting block 48 to move downward through the output shaft. The movement of the second rotating ball block connecting block 48 causes the second rotating ball block 45 to rotate inside the second rotating ball block connecting block 48, while simultaneously causing the first rotating ball connecting block 44 to move downward. The movement of the first rotating ball connecting block 44 causes the second fixing block 38 to be adjusted. At this time, the first rotating ball block 41 at the bottom of the second fixing block 38 rotates inside the base 1, thereby adjusting the angle of the workpiece at the top of the drilling platform 32. Then, the second telescopic motor 43 is started, and the locking arc block 42 is driven by the output shaft to lock the first rotating ball block 41.

[0027] By setting the first rotating ball block 41, the third telescopic motor 46 is started to drive the second rotating ball block connecting block 48 to move, which ultimately tilts the surface of the drilling platform 32. With the detection of the tilt sensor 47, the workpiece to be processed is adjusted to a suitable angle, avoiding the problem of the drill bit 513 being unable to feed in the vertical direction and slipping, which would affect the processing efficiency of the device, thereby improving the processing efficiency of the device.

[0028] By setting the first limit block 34 and starting the first telescopic motor 31, the first limit block 34 is initially fixed to the workpiece to be processed. Then, the first motor 35 is started to drive the second limit block 36 to fix the workpiece to be processed again. This quickly fixes the workpiece while ensuring its stability during the processing, thereby avoiding damage to the workpiece and affecting the processing efficiency, and improving the processing efficiency of the device.

[0030] The sliding support block 54 is slidably connected inside the adjusting support beam 51, and the sliding support block 54 is slidably connected to the second lead screw 53.

The inside of the third motor 56 is fixedly connected to the spur gear 57 through the output shaft.

[0031] A cylinder 58 is fixedly connected to the top of the sliding support plate 55. A third fixing block 59 is fixedly connected to the inside of the cylinder 58 through an output shaft. A fourth motor 510 is fixedly connected to the inside of the third fixing block 59. A drill bit 513 is rotatably connected to the inside of the fourth motor 510. An elastic support rod 511 is fixedly connected to the bottom of the third fixing block 59. An arc-shaped baffle 512 is slidably connected to the surface of the elastic support rod 511.

[0033] In use, after adjusting the workpiece to a suitable position, the second motor 52 is started. The starting of the second motor 52 drives the sliding support block 54 to move through the rotation of the second lead screw 53. The movement of the sliding support block 54 causes the sliding support plate 55 to be adjusted together. Then the third motor 56 is started. The starting of the third motor 56 drives the spur gear 57 to rotate through the output shaft. The rotation of the spur gear 57 causes the sliding support plate 55 to move, thereby adjusting the drill bit 513 to a suitable position. Then the control cylinder 58 is started. The starting of the cylinder 58 drives the third fixing block 59 to move in the direction of the workpiece through the output shaft. At this time, the arc-shaped baffle 512 further fixes the top of the workpiece. Then the fourth motor 510 is started. The starting of the fourth motor 510 drives the drill bit 513 to drill a hole.

[0034] By setting up the arc-shaped baffle 512, the control cylinder 58 starts and drives the arc-shaped baffle 512 to fix the top of the workpiece. Together with the first limit block 34 and the second limit block 36, the workpiece is fixed in all directions, which further increases the stability of workpiece processing. In addition, setting up the arc-shaped baffle 512 can avoid the problem of debris flying around during processing and affecting the processing of the device, thereby improving the processing efficiency of the device.

[0035] By setting up a collection box 62, after the debris slides down the inclined drilling platform 32 to the top of the inclined slide plate 61, the inclined slide plate 61 can be manually moved to allow the impurities to fall into the collection box 62 through the spring at the bottom, thus avoiding the accumulation of impurities and affecting processing efficiency.
