DETAILED DESCRIPTION

[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution: a CNC drilling machine, including a CNC drilling machine body 1, a rotating shaft 2 is provided on the CNC drilling machine body 1, and a drilling tool 5 is provided at one end of the rotating shaft 2 away from the CNC drilling machine body 1 for drilling holes in the material. The bottom of the CNC drilling machine body 1 is rotatably connected to two mounting cylinders 3, and the two mounting cylinders 3 are respectively located on both sides of the rotating shaft 2. The surface of the rotating shaft 2 is fixedly connected to a first gear 4, and the surfaces of the two mounting cylinders 3 are fixedly connected to a second gear 6. The first gear 4 is located between the two second gears 6, and the surfaces of the two second gears 6 are meshed with the surface of the first gear 4, so that when the rotating shaft 2 rotates, the two mounting cylinders 3 can be synchronously driven to rotate, thereby ensuring the smooth operation of the device.

[0026] Furthermore, the inner walls of the two mounting cylinders 3 are slidably connected to a movable disk 10, and the surfaces of the two movable disks 10 are fixedly connected to two winding rods 7. The material of the two winding rods 7 can be magnets, so that the device can adsorb the cut debris to a certain extent when processing ferrous metal, thereby increasing the probability of the winding debris being adsorbed on the surface of the winding rod 7.

[0027] The surface of the winding rod 7 is movably connected to a mounting sleeve 13, and the material of the mounting sleeve 13 can be rubber, so that the mounting sleeve 13 can be more firmly mounted on the surface of the winding rod 7, and at the same time it is convenient for the staff to remove the mounting sleeve 13 from the surface of the winding rod 7, thereby improving the use effect of the device and having a high promotion value.

[0028] The surface of the mounting sleeve 13 is fixedly connected with protrusions 8 that are randomly distributed. The protrusions 8 are arranged so that the chips are swung to the surface of the winding rod 7, which increases the possibility of the chips being wound around the surface of the winding rod 7 and improves the chip collection effect of the device.

[0029] Furthermore, a limiting block 11 is fixedly connected to the surface of the movable disk 10, and two sliding grooves 12 are provided on the inner wall of the mounting cylinder 3. The surface of the limiting block 11 is slidably connected to the inner wall of the sliding groove 12. Therefore, through the setting of the limiting block 11 and the sliding groove 12, it is ensured that when the mounting cylinder 3 rotates, the limiting block 11 can be pushed by the inner wall of the sliding groove 12, thereby driving the movable disk 10 and the winding rod 7 to rotate, and at the same time does not affect the mutual sliding between the movable disk 10 and the mounting cylinder 3, thereby ensuring the smooth operation of the device.

[0030] A spring 9 is fixedly connected to the surface of the movable disk 10, and the end of the spring 9 away from the movable disk 10 is fixedly connected to the inner wall of the mounting cylinder 3, so as to drive the movable disk 10 and the winding rod 7 to reset. The inner wall of the mounting cylinder 3 is conical, and the setting of the conical inner wall of the mounting cylinder 3 enables the winding chips on the surface of the winding rod 7 to be compressed under the extrusion of the inclined surface of the mounting cylinder 3, thereby ensuring that the winding chips can smoothly enter the mounting cylinder 3, thereby ensuring the smooth operation of the device.

[0031] Furthermore, a pressure plate 15 is provided at one end of the winding rod 7 away from the mounting cylinder 3, and the surface of the pressure plate 15 is rotatably connected to two rotating disks 14, and the surfaces of the four winding rods 7 are fixedly connected to the surfaces of the two rotating disks 14 respectively. Then, through the setting of the pressure plate 15, the material can be pressed when the device is drilling a hole in the material, thereby reducing the movement of the material during drilling and improving the stability of the device during drilling. A through hole 16 is provided on the surface of the pressure plate 15, and the through hole 16 corresponds to the drilling tool 5, providing space for the drilling tool 5 to pass through, thereby avoiding affecting the drilling of the device.

[0032] Specifically, when drilling, the rotation of the rotating shaft 2 drives the first gear 4 to rotate, and drives the two mounting cylinders 3 to rotate through the meshing connection, thereby driving the four winding rods 7 to perform circular motion. When the drilling tool 5 is drilling, the chips generated swing back and forth, thereby hitting the surface of a winding rod 7, and are bound to the winding rod 7 under the obstruction of magnetic force or protrusion 8, and then the chips are wound under the synchronous rotation of the two winding rods 7, and then the chips on the drilling tool 5 are pulled, thereby avoiding the chips always adhering to the surface of the drilling tool 5, thereby affecting the drilling of the drilling tool 5 and reducing the service life of the drilling tool 5, thereby improving the use effect of the device, and having high promotion value and practicality.

[0033] Working principle: The rotation of the rotating shaft 2 drives the two mounting cylinders 3 and the four winding rods 7 to perform circular motion. As the chips on the drilling tool 5 swing back and forth, they hit the surface of a winding rod 7 and are blocked by magnetic force or protrusions 8 and are bound to the winding rod 7. Then, under the synchronous rotation of the two winding rods 7, the chips are wound around and then pulled on the drilling tool 5, thereby preventing the chips from always adhering to the surface of the drilling tool 5.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
