Pulling out the collection box will clean up the collected waste and dust, improving the convenience of waste collection and treatment.

[0019] 4. After the air pump is started, the door and window frames are covered on the adsorption holes, which creates a negative pressure inside the adsorption holes, causing the door and window frames to be adsorbed onto the machine body, thus facilitating the fixation of the door and window frames.

[0020] 5. After drilling is completed, start the hydraulic cylinder to move the drill rod upward. At this time, push the push-pull rod to move the movable plate, the second motor, the second mounting base and the second grinding disc towards the drilling groove until the semi-circular structure of the movable plate is in contact with the inner wall of the drilling groove. During the process of pushing the push-pull rod, start the second motor to drive the second mounting base and the second grinding disc to rotate, so that the second grinding disc grinds the burrs at the lower end of the hole, improving the removal effect of burrs on the side of the hole.

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides an embodiment of a drilling device for door and window processing, comprising a body 1, a column 2 fixedly mounted on the top of the body 1, a first motor 5 mounted on the column 2 via a lifting assembly, the lifting assembly including a lifting groove fixedly opened inside the column 2, a hydraulic cylinder 3 fixedly mounted at the bottom of the lifting groove, a lifting plate 4 fixedly connected to the telescopic end of the hydraulic cylinder 3, the first motor 5 fixedly mounted at the bottom of the end of the lifting plate 4, and a drill rod 6 fixedly connected to the drive end of the first motor 5. When using this utility model, the door and window frame is placed on the body 1 so that the area to be drilled is directly opposite the drill rod 6. The hydraulic cylinder 3 and the first motor 5 are started, thereby driving the drill rod 6 to move downwards and rotate, thus drilling the hole at the desired location on the door and window frame.

[0030] Considering that burrs may appear on the sides of the hole during drilling, which could potentially scratch workers' arms during subsequent installation of doors and windows, posing a safety hazard, this utility model provides a grinding component on the outer ring of the drill rod 6. The grinding component includes a first mounting base 7, which is fixedly mounted on the outer ring of the drill rod 6. A first grinding disc 8 is fitted to the bottom of the first mounting base 7. A through hole adapted to the drill rod 6 is fixedly opened in the middle of the first grinding disc 8. Three threaded cylinders 9 are fixedly mounted on the upper surface of the first grinding disc 8 in a ring. Three insertion holes 10 are fixedly mounted inside the first mounting base 7 in a ring. The threaded cylinders 9 are inserted into the insertion holes 10. Bolts 11 are threadedly connected inside the threaded cylinders 9, and the nut end of the bolts 11 is located on the upper surface of the first mounting base 7.

[0031] Specifically, when the drill rod 6 rotates downwards to drill a hole, it drives the first mounting base 7 and the first grinding disc 8 to rotate synchronously. This allows the first grinding disc 8 to fit against the door and window frame, enabling the grinding of the drilled area on the door and window frame and the removal of burrs on the sides of the hole. This solves the problem that existing drilling devices for door and window processing are not convenient for removing burrs on the sides of the hole, which could cause workers to scratch their arms and create safety hazards when installing doors and windows.

[0032] When the first grinding disc 8 needs to be replaced, the bolt 11 can be unscrewed from the inside of the threaded cylinder 9 to remove the first grinding disc 8. After replacing it with a new first grinding disc 8, it can be installed in reverse order, which improves the efficiency of disassembly and assembly of the first grinding disc 8 and thus improves the ease of maintenance of the device.

[0033] In order to collect the waste generated during drilling, a collection chamber 21 and a drill groove 12 are fixedly installed inside the machine body 1. An air pump 24 is fixedly installed on the side wall of the machine body 1. The drill groove 12 is located directly below the drill rod 6. The inner diameter of the drill groove 12 is larger than the outer diameter of the drill rod 6. An air outlet is provided on the side of the collection chamber 21. A filter screen 23 is fixedly installed inside the air outlet. The air outlet and the air inlet of the air pump 24 are connected to each other. A collection box 22 is slidably installed inside the collection chamber 21.

[0034] After the air pump 24 is started, the external air enters the collection chamber 21 through the drill groove 12. The waste and dust carried in are filtered by the filter screen 23 and then discharged by the air pump 24 to purify the air. The collected waste and dust accumulate inside the collection box 22. Pulling out the collection box 22 can clean the collected waste and dust, improving the convenience of waste collection and treatment.

[0035] Meanwhile, in order to limit the door and window frame, several adsorption holes 25 are fixedly opened inside the body 1. The adsorption holes 25 penetrate the upper surface of the body 1, and the bottom of the adsorption holes 25 is connected to the collection chamber 21. After the air pump 24 is started, since the door and window frame covers the adsorption holes 25, a negative pressure is formed inside the adsorption holes 25, which causes the door and window frame to be adsorbed onto the body 1, thus facilitating the fixation of the door and window frame.

[0036] To grind the burrs at the bottom of the hole, a movable groove 13 is fixedly installed inside the machine body 1. The movable groove 13 and the drill groove 12 are interconnected. A movable plate 14 is slidably installed at the bottom of the movable groove 13. One end of the movable plate 14 has a semi-circular structure, and the outer diameter of the semi-circular structure is the same as the inner diameter of the drill groove 12. Push-pull rods 18 and a second motor 15 are fixedly installed at both ends of the top of the movable plate 14, respectively. A second mounting base 16 is fixedly connected to the drive end of the second motor 15. A second grinding disc 17 is installed on the top of the second mounting base 16. The height of the upper surface of the second grinding disc 17 is the same as the height of the upper surface of the machine body 1. The outer diameters of the second grinding disc 17 and the second mounting base 16 are both smaller than the inner diameter of the drill groove 12.

[0037] Specifically, after drilling is completed, hydraulic cylinder 3 is activated, which drives drill rod 6 to move upward. At this time, push-pull rod 18 is pushed, which drives movable plate 14, second motor 15, second mounting base 16 and second grinding disc 17 to move towards drill groove 12 until the semi-circular structure of movable plate 14 is in contact with the inner wall of drill groove 12. During the process of pushing push-pull rod 18, second motor 15 is activated, which drives second mounting base 16 and second grinding disc 17 to rotate, so that second grinding disc 17 grinds the burrs at the lower end of the hole, improving the burr removal effect on the side of the hole.

[0038] Furthermore, limit plates 20 are fixedly provided on both sides of the movable plate 14, and a limit groove 19 adapted to the limit plate 20 is provided inside the body 1. The movable groove 13 and the limit groove 19 are connected to each other. This arrangement allows the movable plate 14 to move stably inside the movable groove 13. When the second grinding disc 17 needs to be replaced, the entire movable plate 14 can be pulled out from inside the movable groove 13, which facilitates the replacement of the second grinding disc 17.

[0039] Working principle: When using this invention, place the door / window frame on the machine body 1, ensuring the drilling point is directly opposite the drill rod 6. After starting the air pump 24, the door / window frame covers the suction hole 25, creating a negative pressure inside the suction hole 25, which in turn causes the door / window frame to be adhered to the machine body 1, facilitating its fixation. Then, start the hydraulic cylinder 3 and the first motor 5, causing the drill rod 6 to rotate while moving downwards, thus drilling the hole in the door / window frame. Once the first grinding disc 8 is in contact with the door / window frame, it can grind the drilling location and remove burrs from the sides of the hole. Simultaneously, external air enters the collection chamber 21 through the drill groove 12, filtering out any entrained debris and dust. After being filtered by mesh 23, the air is discharged through air pump 24 to purify the air. The collected waste and dust accumulate inside the collection box 22. After drilling is completed, hydraulic cylinder 3 is started in reverse to drive drill rod 6 to move upward. At this time, push-pull rod 18 is pushed to drive movable plate 14, second motor 15, second mounting base 16 and second grinding disc 17 to move towards the drill groove 12 until the semi-circular structure of movable plate 14 is attached to the inner wall of drill groove 12. During the process of pushing push-pull rod 18, second motor 15 is started to drive second mounting base 16 and second grinding disc 17 to rotate, so that second grinding disc 17 grinds the burrs at the lower end of the hole. Finally, air pump 24 is turned off and the drilled door and window frame can be removed from machine body 1.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
