Description

Technical Field

[0001] This utility model relates to the field of drill bit cleaning technology, and in particular to a drilling machine for metal door frames. Background Technology

[0002] Copper doors are doors made primarily of copper (or copper alloys). They are a type of metal door and are known for their safety and durability. They are commonly used in high-end locations such as shopping malls and hotels.

[0003] Currently, during the production of copper door frames, holes need to be drilled to allow the frame to be installed with other components or carriers. During drilling, drill bits leave behind debris. Although the retraction motion of the drill bit can remove some of this debris, the cleaning effect is always limited. More specifically:

[0004] When the drilling machine is drilling, the drill bit rotates (the rotation meter indicates forward rotation) and drills holes in the door frame. After drilling is completed, the drill bit also rotates (the rotation meter indicates reverse rotation, which is the opposite of forward rotation) when it retracts from the hole. Through the reverse rotation during the retraction process, the drill bit can throw off its own debris. However, the method of throwing off impurities by rotating the drill bit is very limited in cleaning the drill bit, and it still requires workers to clean the drill bit from time to time.

[0005] Therefore, existing drilling machines need to be improved to enhance their ability to clean drill bits. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drilling machine for metal door frames, which aims to solve the problems mentioned in the background technology.

[0007] The technical solution of this utility model is implemented as follows: a drilling machine for metal door frames, comprising:

[0008] The body, on which a clamping assembly for fixing the door frame panel is installed;

[0009] The drilling assembly consists of at least a drill bit rotatably mounted on the machine body and a motor for controlling the forward or reverse rotation of the drill bit;

[0010] A moving component, mounted on the machine body, is used to control the drilling component to reciprocate along a straight feed path. The machine body is also equipped with a dust collection component and an air source component. The dust collection component is located on the feed path of the drill bit and has a dust collection chamber for the drill bit to enter.

[0011] When the drill bit enters the dust collection chamber and reverses direction, the air source component is activated to create negative pressure inside the dust collection chamber and introduces airflow from the chamber opening to clean the drill bit.

[0012] By adopting the above technical solution:

[0013] This invention improves the cleaning effect of drill bits by adding a dust collection component to an existing drilling machine. The dust collection component is located on the feed path of the drill bit. After the drill bit drills a hole in the door frame, it enters the dust collection chamber for dust collection. When the drill bit enters the dust collection chamber, the activated air source component can complete the dust collection process.

[0014] Preferably, the dust collection assembly includes:

[0015] The vacuum cleaner is mounted on the main body and has a dust filter chamber that extends downwards from top to bottom.

[0016] The dust discharge chamber is formed on the suction body and is located below the dust filter chamber;

[0017] The opening is formed on the side of the dust filter chamber near the drill bit and allows the drill bit to enter the dust filter chamber;

[0018] A columnar filter screen is fixedly connected to the side wall of the dust filtration chamber near the drill bit, and is coaxially arranged with the chamber opening;

[0019] The dust suction chamber is formed between the dust filtration chamber and the dust discharge chamber, and a lifting plate that can be controlled by the first driver is provided at the bottom of the columnar filter screen.

[0020] Preferably, the dust collection body is provided with a dust discharge port, and a cover plate is detachably connected to the dust discharge port.

[0021] Preferably, the dust collection body is provided with an exhaust port for installing an air source component, and the air source component is a centrifugal fan located at the exhaust port.

[0022] By adopting the above technical solution:

[0023] This invention uses a columnar filter to concentrate waste debris in the vacuum cleaner body during vacuuming, thereby preventing the waste debris from being discharged by the airflow through the centrifugal fan and thus avoiding damage to the centrifugal fan.

[0024] Furthermore, in order to ensure that impurities in the dust filter chamber are discharged in a timely manner, this utility model also provides a dust discharge chamber below the dust filter chamber. The waste debris in the dust filter chamber can enter the dust discharge chamber through the lifting and lowering movement of the lifting plate. That is, when the lifting plate descends, the lifting plate separates from the columnar filter screen, and the impurities in the dust filter chamber can enter the dust discharge chamber.

[0025] Preferably, the bottom of the dust discharge chamber is inclined towards the dust discharge port.

[0026] Preferably, the bottom of the dust extraction chamber is composed of two symmetrically arranged and inclined dust guide plates, with a mounting cavity formed between the two dust guide plates. A striking structure for striking the dust guide plates is provided within the mounting cavity, wherein the striking structure includes:

[0027] The support plate consists of a first support plate and a second support plate that are spaced apart and fixedly connected within the mounting cavity;

[0028] The hinge joint is formed on the support plate;

[0029] A striking shaft, hinged to a pivot at the hinge joint;

[0030] One end of the striking shaft can be raised and lowered by a second driver.

[0031] Preferably, one end of the striking shaft is covered with a rubber sleeve.

[0032] Preferably, the striking shaft comprises:

[0033] The outer shaft is hinged to the hinge interface via the rotating shaft;

[0034] The inner cavity is coaxially formed on the outer shaft, and one end of it passes through one end of the outer shaft;

[0035] The inner shaft is partially located in the inner cavity, with one end extending out of the inner cavity and able to slide axially relative to the outer shaft.

[0036] The end of the inner shaft away from the outer shaft is hinged to the driving end of the second driver.

[0037] Preferably, the first driver and the second driver are cylinders.

[0038] By adopting the above technical solution:

[0039] To facilitate the discharge of waste debris, the bottom of the dust discharge chamber is designed to be inclined, thereby guiding the waste debris towards the dust discharge port and making it easier to clean the waste debris inside the dust discharge chamber.

[0040] Secondly, in order to further facilitate the cleaning of waste, this utility model also provides a striking structure. The striking structure can be used to strike the dust guide plate, causing the dust guide plate to vibrate, thereby preventing the waste on the dust guide plate from moving to the lower position of the dust guide plate. Since the dust discharge port is located at the lower position of the dust guide plate, the waste will move towards the dust discharge port, thus making it easier to clean the waste in the dust discharge chamber.

[0056] 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.

[0057] Example 1:

[0058] like Figures 1-11 As shown, this embodiment provides a drilling machine for metal door frames, including:

[0059] The machine body 10 is equipped with a clamping assembly for fixing the door frame panel. In this embodiment, the machine body 10 consists of a machine plate 100 and support legs 101 for supporting the machine plate 100. There are four support legs 101 in this embodiment, and one end is fixedly connected to the machine plate 100. The machine plate 100 is also provided with a splash guard 102 and a hydraulic seat 103. The splash guard 102 and the machine plate 100 form a downwardly recessed cavity. In this way, the waste generated by drilling will not easily splash out of the machine body 10. The machine plate 100 is provided with a waste port 100a. A collection box 100b is placed below the waste port 100a. The waste generated by drilling and falling on the machine plate 100a can be discharged through the waste port.

[0060] The drilling assembly consists of at least a drill bit 20 rotatably mounted on the body 10 and a motor 21 for controlling the forward or reverse rotation of the drill bit 20. In this embodiment, the drilling assembly includes a lifting platform 22, and a control cabinet 23 is provided on one side of the lifting platform 22. The control cabinet 23 is used to control the operation of each actuator in this embodiment. The bottom of the lifting platform 22 is controlled by the motor 21 to rotate the drill bit 20. In the prior art, the motor 21 can control the rotation of the drill bit 20 through a transmission shaft.

[0061] The moving component is mounted on the machine body 10 and is used to control the drilling component to move back and forth along a straight feed path. In this embodiment, the moving component is a hydraulic cylinder 30 mounted on the hydraulic base 103. The hydraulic cylinder 30 is used to control the lifting and lowering of the lifting platform 22. At the same time, the hydraulic base 103 is provided with a limiting guide rail 31, and the lifting platform 22 is provided with a limiting slider 32 that can move on the limiting guide rail 31.

[0062] The clamping assembly in this embodiment includes:

[0063] The clamping base 40 is fixed on the machine plate 100;

[0064] A clamping cylinder 41 is mounted on the clamping seat 40;

[0065] Base 42 is fixed to clamping seat 40;

[0066] The clamping block 43 is hinged to the base 42 via the hinge block 43a. One end of the hinge block 43a is hinged to the base 42 via a shaft, and the other end of the clamping block 43a is also hinged to the clamping block 43 via a shaft. In this embodiment, the output end of the clamping cylinder 41 is also hinged to one end of the clamping block via a shaft. Thus, when the output end of the clamping cylinder 41 (that is, one end of the piston) moves, the other end of the clamping block (the end of the clamping block away from the hinge between the clamping block and the clamping cylinder, also called the clamping end) can be raised or lowered by controlling one end of the clamping block. When the clamping end of the clamping block lowers, the clamping block clamps one end of the door frame through its cooperation with the clamping seat 40, and vice versa.

[0067] In this embodiment, the body 10 is also provided with a dust collection component 5 and an air source component. The dust collection component 5 is located on the feed path of the drill bit 20 and has a dust collection chamber for the drill bit 20 to enter. In this embodiment, the feed path of the drill bit moves up and down. Therefore, the dust collection component 5 in this embodiment can be set below the drill bit 20.

[0068] When the drill bit 20 enters the dust collection chamber and reverses direction, the air source component is activated to create negative pressure in the dust collection chamber and introduces airflow from the opening of the dust collection chamber to clean the drill bit 20.

[0069] In this embodiment: the vacuuming component 5 includes:

[0070] The vacuum cleaner 50 is mounted on the base plate 100 of the body 10 and has a dust filter chamber 51 that extends from top to bottom.

[0071] The dust discharge chamber 52 is formed on the suction body 50 and is located below the dust filter chamber 51;

[0072] The opening 53 is formed on the side of the dust filter chamber 51 near the drill bit 20, and allows the drill bit 20 to enter the dust filter chamber 51;

[0073] A columnar filter screen is fixedly connected to the side wall of the dust filter chamber 51 near the drill bit 20, and is coaxially arranged with the chamber opening 53;

[0074] The dust suction chamber is formed between the dust filter chamber 51 and the dust discharge chamber 52, and a lifting plate that can be controlled by the first driver is provided at the bottom of the columnar filter screen.

[0075] In this embodiment, the top of the vacuum cleaner 50 is detachably connected to a top plate 50a via bolts. The top plate 50a is provided with a support head 50b and a threaded hole 50c for the bolts to pass through. The vacuum cleaner 50 should also be provided with a matching threaded hole, so that the bolts can install the top plate onto the vacuum cleaner 50. The support head 50b is located between the clamping seats and is used to support the bottom of the drilled position of the door frame. The cavity 53 is formed on the support head 50b. The side of the top plate 50a away from the support head 50 (that is, the side located in the dust filter chamber 51) is fixedly connected to an annular base 50e by several support rods 50d. The columnar filter screen is a filter bag 50f. The two ends of the filter bag are fixedly connected between the top plate and the annular base 50e respectively. The support rods are located inside the filter bag to prevent the filter screen from shrinking (that is, the support rods are used to support the filter screen to expand).

[0076] In this embodiment, the lifting plate is a plate 540 located below the annular base 50e. A guide block 541 is provided on the plate 540. The top of the guide block is a spherical or curved surface, and the maximum diameter of the guide block (that is, the diameter of the contact surface between the guide block and the plate 540) is greater than the inner diameter of the annular base. Thus, when the lifting plate rises and the guide block 541 contacts the annular base 50e, the inner circle of the annular base can be closed.

[0077] In this embodiment, the top outer wall of the plate 540 (the outer wall on which the guide block 541 is installed) is gradually inclined from the connection with the guide block 541 toward the edge of the plate 540 to avoid impurities accumulating on the plate 540.

[0078] In this embodiment, the first actuator is a first cylinder 551. In this embodiment, two cylinder mounting slots 550 are recessed in the wall of the dust filter chamber. The slot wall of the cylinder mounting slot 550 is provided with an air pipe port 552 through which the pneumatic pipe (including the air supply pipe and the exhaust pipe) of the first cylinder passes. The pneumatic pipe of the first cylinder can pass through the air pipe port 552 and be connected to the pneumatic system, thereby realizing the pneumatic system controlling the first cylinder. The pneumatic system is a mature existing technology and will not be described in detail in this embodiment.

[0079] The bottom of the cylinder mounting slot 550 has an opening through which the piston shaft of the first cylinder can pass. The piston shaft of the first cylinder is connected to the connecting rod 540a on the plate 540, so that the first cylinder can control the lifting plate to move up and down.

[0080] The cylinder mounting slot 550 is provided with a clamping plate 556. The clamping plate 556 has an insertion part 556a and a clamping part 556b. After the first cylinder is installed, the insertion part of the clamping plate 556 is inserted into the gap between the first cylinder and the cylinder mounting slot, and the clamping plate is fastened, so that the clamping part on the clamping plate contacts the outer wall of the first cylinder, thereby stabilizing the first cylinder.

[0081] In this embodiment: the dust suction body 50 is provided with a dust discharge port 60, and a cover plate 61 is detachably connected to the dust discharge port 60 by bolts.

[0082] In this embodiment: the dust collector 50 is provided with an exhaust port 62 for the installation of an air source component, and the air source component is a centrifugal fan 63 located at the exhaust port 62.

[0083] In this embodiment, the bottom of the dust discharge chamber 52 is inclined toward the dust discharge port 60.

[0084] In this embodiment, a buffer plate 65 is provided at the connection between the dust discharge chamber 52 and the dust filter chamber 51. The buffer plate 65 is inclined, and the angle of inclination can be determined according to the situation. It is most suitable for the included angle between the buffer plate 65 and the dust filter chamber 51 to be an obtuse angle (such as 150°). The length 65 of the buffer plate in the height direction should cover the width of the connection position between the dust filter chamber 51 and the dust discharge chamber 52 as much as possible, so that the impurities falling from the dust filter chamber can fall onto the buffer plate first, and then enter the dust discharge chamber through the guidance of the buffer plate. It should be noted that when setting the length of the buffer plate, the gap between it and the bottom of the dust discharge chamber 52 should also be taken into account. This gap should be able to allow impurities to pass through. Otherwise, the impurities will accumulate on the buffer plate and cannot move towards the dust discharge port.

[0085] In this embodiment, an exhaust pipe 66 extends outward from the side wall of the dust collector 50. One end of the exhaust pipe 66 is connected to the dust filter chamber 51, and the other end is an exhaust port. An observation port 660 is provided on the outer wall of the exhaust pipe 66. A sealing plate 661 is detachably connected to the through port 660 by bolts. At least one stepped surface is provided on the pipe wall of the exhaust pipe 66. In this invention, a dust filter can be installed in the exhaust pipe 66 through the observation port 660. The dust filter includes a housing 662, a cavity 663 is provided in the housing 662, and two sets of through-hole air ports 664 are provided on the outer wall of the housing 662. A dust filter screen 665 is fixedly connected between the air ports 664.

[0086] In this embodiment, the side wall of the outer casing 662 is provided with a protrusion 662a, and the stepped surface of the exhaust pipe 660 is provided with a groove 662b for the protrusion 662a to be inserted into.

[0087] The principle of this embodiment is:

[0088] 1. When drilling, place the door frame panel between the clamping seats, and use the clamping cylinder to control the clamping block to fix the door frame panel. Then, use the hydraulic cylinder to control the drilling assembly to descend, and use the drill bit to drill holes in the door frame panel.

[0089] 2. After drilling is completed, the drill bit passes through the door frame panel and enters the dust filter chamber through the cavity on the support head. When the centrifugal fan starts, airflow is introduced from the cavity and enters the dust filter chamber. Then, it passes through the columnar filter screen and is discharged through the exhaust pipe. When the airflow is flowing, the drill bit is controlled to rise and reverse at the same time. The reverse reversal can remove dust and suck up the dust from the drill bit through the flowing airflow, thus cleaning the drill bit.

[0090] 3. After cleaning is completed, the first cylinder controls the lifting plate to descend and opens the lower opening of the columnar filter screen. The impurities in the columnar filter screen fall freely into the dust discharge chamber (the centrifugal fan can stop running during this process). When the impurities in the dust discharge chamber accumulate to a certain extent, the dust discharge chamber can be cleaned by opening the cover plate.

[0091] In addition, this embodiment also has a dust filter installed on the exhaust pipe to filter out impurities, and when the dust suction effect of the centrifugal fan decreases, the dust filter can be cleaned by opening the sealing plate and removing it through the observation port.

[0092] Example 2 differs from Example 1 in that:

[0093] like Figures 12-14 As shown, in this embodiment, the bottom of the dust extraction chamber 52 is composed of two symmetrically arranged and inclined dust guide plates 70, forming an installation cavity 71 between the two dust guide plates 70. A striking structure for striking the dust guide plates 70 is provided within the installation cavity 71. The opening of the installation cavity 71 is located at the bottom of the suction body 50, and a base plate 72 is installed thereon by bolts. The striking structure includes:

[0094] The support plate is composed of a first support plate 811 and a second support plate 812 that are spaced apart and fixedly connected to the base plate 72;

[0095] The hinge interface 813 is formed on the support plate;

[0096] The striking shaft is hinged to the hinge interface 813 via the pivot 82.

[0097] One end of the striking shaft can be raised and lowered by a second driver.

[0098] In this embodiment: one end of the striking shaft is wrapped with a rubber sleeve 84.

[0099] In this embodiment: the striking shaft includes:

[0100] The outer shaft 850 is hinged to the hinge interface 813 via the rotating shaft 82;

[0101] The inner cavity 851 is coaxially formed on the outer shaft 850, and one end of it passes through one end of the outer shaft 850;

[0102] The inner shaft 852 is partially located in the inner cavity 851, with one end extending out of the inner cavity 851, and can slide axially relative to the outer shaft 850.

[0103] The inner shaft 852 is hinged to the drive end of the second driver at one end away from the outer shaft.

[0104] In this embodiment: the second driver is a second cylinder 88, and the base plate may be provided with an air port (not shown in the figure) for the pneumatic pipe of the second cylinder to pass through, so as to facilitate the pneumatic system to control the second cylinder.

[0105] refer to Figures 12-14 In this embodiment, a striking structure is provided below the dust guide plate. When cleaning the dust discharge chamber, the inner shaft can be raised and lowered by the second cylinder, and the outer shaft can be made to make lever movement. One end of the outer shaft is used to strike the dust guide plate, thereby moving the impurities on the dust guide plate to the lowest point, which makes it easier to clean the impurities in the dust discharge chamber.

[0106] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
