[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This application discloses a drilling device for processing steel components, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a first support bracket 1 and a second support bracket 2. The second support bracket 2 is slidably disposed on one side of the first support bracket 1. Both the first support bracket 1 and the second support bracket 2 are slidably disposed along their own length direction with a clamping base 3. The clamping base 3 is provided with a clamping assembly 31 for clamping steel components. A drilling support seat 4 is provided on the side of the first support bracket 1 away from the second support bracket 2 and is movable along the length direction of the first support bracket 1. A first drilling lifting seat 41 is vertically and vertically disposed on the drilling support seat 4. A support arm 42 is slidably disposed on the first drilling lifting seat 41 parallel to the sliding direction of the second support bracket 2. A rotating arm 43 is rotatably disposed at the end of the support arm 42. A drilling device 44 is disposed on the rotating arm 43.

[0026] The first support bracket 1 is equipped with a first limiting component 21 to restrict the movement of the second support bracket 2, and the clamping base 3 is equipped with a second limiting component 32 to restrict its own movement. By driving the second support bracket 2 to move, the distance between the second support bracket 2 and the first support bracket 1 can be adjusted, allowing the first support bracket 1 and the second support bracket 2 to support steel components of different widths. By sliding the clamping base 3 on the first support bracket 1 and the second support bracket 2, the position of the clamping base 3 in clamping the steel component can be adjusted, and the steel component can be fixed by the clamping component 31.

[0027] Reference Figure 5 and Figure 6 The drilling support 4 is equipped with a first driving member 401 for moving itself on the ground, a second driving member 411 for driving a first drilling lifting seat 41, a third driving member 421 for driving a support arm 42, and a fourth driving member 431 for driving a rotating arm 43. The movement of the first drilling lifting seat 41 and the support arm 42 allows the drilling device 44 to be positioned above / below the clamping assembly 31. The first driving member 401 drives the drilling support 4 to move, enabling the drilling device 44 to drill holes at different locations on the steel component. The fourth driving member 431 drives the rotating arm 43 to rotate, allowing the drilling device 44 to drill holes on both sides of the steel component when positioned above / below the clamping assembly 31.

[0028] In this embodiment, a first auxiliary support seat 5 is provided between the first support bracket 1 and the second support bracket 2. The bottom of the first auxiliary support seat 5 is slidably supported on the ground by casters 51. The first auxiliary support seat 5 is linearly slidably connected to the drilling support seat 4 by a guide rod. A second magnetic attractor is provided on the rotating arm 43 for magnetically connecting with the first auxiliary support seat 5. When the rotating arm 43 is lowered with the first drilling lifting seat 41, and the support arm 42 moves downward to process the steel component from bottom to top, the rotating arm 43 is magnetically connected to the first auxiliary support seat 5 by the second magnetic attractor, pushing the first auxiliary support seat 5 to maintain its support under the rotating arm 43. When the drilling device 44 drills a hole in the steel component, it can play an auxiliary support role, preventing the support arm 42 from bending due to suspending the drilling device 44.

[0029] Furthermore, the drilling support 4 is also provided with a first magnetic attractor for magnetically attracting the first auxiliary support 5. When the support arm 42 retracts, the first magnetic attractor attracts the first auxiliary support 5 and restricts the retraction of the first auxiliary support 5, thereby causing the rotating arm 43 to disengage from the first auxiliary support 5. At the same time, the first auxiliary support 5 is magnetically fixed, keeping the first auxiliary support 5 stable when the drilling support 4 moves.

[0030] Furthermore, on the drilling support base 4, above the first drilling lifting base 41, there is a second auxiliary support base 6. The second auxiliary support base 6 is vertically slidably connected to the drilling support base 4. The drilling support base 4 is provided with a limiting step above the clamping machine base 3 to support the second auxiliary support base 6 and restrict the second auxiliary support base 6 from continuing to move downward.

[0031] An auxiliary support rod 61 is slidably mounted on the second auxiliary support base 6 along the sliding direction of the support arm 42. The end of the auxiliary support rod 61 is magnetically connected to the rotating arm 43 via a second magnetic attractor. When the drilling device 44 rises with the first drilling lifting seat 41 and advances above the first support bracket 1, it is connected to the rotating arm 43 via the auxiliary support rod 61. This allows the auxiliary support rod 61 to provide auxiliary support for the rotating arm 43 and the support arm 42, improving the stability of the drilling device 44 when machining the upper surface of the steel component. Furthermore, a third magnetic attractor or a limiting step can also be provided on the second auxiliary support base 6. This allows the auxiliary support rod 61 to detach from the rotating arm 43 when the support arm 42 slides on the first drilling lifting seat to allow the rotating arm 43 and the drilling device 44 to move away from above the first support bracket 1, thus not affecting the movement of the first drilling lifting seat 41.

[0032] In this embodiment, the first limiting component 21 can be a lead screw and a drive motor. The lead screw is rotatably connected to the first support bracket 1. A set of lead screws can be provided on one side of the first support bracket 1, or a set can be provided on both sides of the first support bracket 1. The drive motor is connected to the lead screw for driving the lead screw to rotate. A lead screw sleeve is provided on the second support bracket 2 and is threadedly connected to the lead screw. The distance between the second support bracket 2 and the first support bracket 1 is adjusted by driving the lead screw to rotate through the drive motor.

[0033] The second limiting component 32 can be a limiting screw. A screw sleeve is provided on the clamping base 3. The limiting screw is threadedly connected inside the screw sleeve and can abut against the first support bracket 1 / second support bracket 2. The first driving component 401 can also be a screw and drive motor structure. The screw is rotatably mounted on the ground / first support bracket 1. The drive motor is used to drive the screw to rotate. A screw sleeve that cooperates with the screw is provided on the drilling support 4. The screw and the screw sleeve are threadedly engaged. By rotating the screw, the drilling support 4 moves linearly to one side of the first support bracket 1. The third driving component 421 can be a drive motor and a rack. A rack is fixed along the length of the support arm 42. The drive motor is fixed on the drilling lifting base. The output end of the drive motor is connected to a gear and meshes with the rack. The fourth driving component 431 can be a drive motor, which is fixedly mounted on the support arm 42. A driven gear is coaxially arranged on the rotating arm 43 with the shaft of the rotating arm 43, and the output shaft of the drive motor meshes with the driven gear through the gear. In this embodiment, both the first support bracket 1 and the second support bracket 2 are provided with guide grooves along their own length direction. Rollers 33 are rotatably arranged on the clamping base 3. The clamping base 3 rolls in contact with the guide grooves through the rollers 33, so that the clamping base 3 can move flexibly on the first support bracket 1 and the second support bracket 2. The clamping assembly 31 may specifically include a lower clamping seat 34 and an upper clamping seat 35. The lower clamping seat 34 is fixedly connected to the clamping base 3, and the upper clamping seat 35 is vertically slidably arranged above the clamping base 3 through a guide rod vertically fixedly connected to the top wall of the clamping base 3. A fifth driving component 36 is provided on the clamping base 3 for driving the upper clamping seat 35 to rise and fall. The fifth driving component 36 can be a screw, which is vertically and rotatably mounted on the clamping base. A handle 712 is fixed at the top of the screw, and a screw sleeve is fixed on the upper clamping seat 35. The screw thread passes through the threaded sleeve.

[0034] Reference Figure 4Furthermore, a third auxiliary support seat 7 for supporting steel components can be provided on the side of the second support bracket 2 near the first support bracket 1. Several ball bearings are rolled on the top of the third auxiliary support seat 7, and a vertical rod 73 is provided at the bottom of the third auxiliary support seat 7. At least three casters 51 are provided at the bottom of the vertical rod 73, allowing the third auxiliary support seat 7 to be supported on the ground by the casters 51. A floating seat 71 is slidably provided on the second support bracket 2 along its length. A first elastic component is provided on the second support bracket 2 to drive the floating seat 71 to move and center on the second support bracket 2. Two sliding blocks 72 are slidably provided on the floating seat 71 along its sliding direction. Two connecting rods 74 are hinged to the bottom of the vertical rod 73, and the other end of the connecting rods 74 is hinged to the sliding blocks 72. A second elastic component is provided on the floating seat 71 to drive the two sliding blocks 72 to move and center on the floating seat 71 so that the two connecting rods 74 form an included angle. Through the action of the floating seat 71 and the first and second elastic components, the third auxiliary support seat 7 can move flexibly relative to the second support bracket 2 after being subjected to external force.

[0035] Specifically, the first elastic component includes two first springs 75, and a first mounting plate 76 is fixedly mounted on the floating seat 71. The two first springs 75 are located on both sides of the first mounting plate 76, with one end of each spring fixedly connected to the first mounting plate 76 and the other end fixedly connected to the second support bracket 2. The second elastic component includes two second springs 77, which are located at both ends of the floating seat 71. One end of each spring 77 is fixedly connected to the floating seat 71 and the other end is fixedly connected to the sliding block 72. A guide plate 52 is also provided on the first auxiliary support base 5. The side of the guide plate 52 facing the second support bracket 2 is set as a conical surface, and the conical angle of the guide plate 52 is obtuse. A rotating wheel 53 is rotatably mounted on the first auxiliary support base 5 at the conical part of the guide plate 52. When the drilling device 44 moves between the first support bracket 1 and the second support bracket 2 to drill holes in the bottom wall of the steel component, the guide plate 52 pushes the third auxiliary support base 7 to move, allowing the third auxiliary support base 7 to elastically avoid obstacles.

[0036] Furthermore, an adjusting screw 711 is threaded onto the floating seat 71. A handle 712 is fixedly connected to one end of the adjusting screw 711, and a connecting plate 713 is rotatably mounted on the other end of the adjusting screw 711. A connecting seat is hinged to the upright 73. A third spring 714 is positioned between the connecting plate 713 and the connecting seat. One end of the third spring 714 is fixedly connected to the connecting plate 713, and the other end is fixedly connected to the connecting seat. For steel components of different widths to be processed, rotating the adjusting screw 711 adjusts the distance by which the third auxiliary support seat 7 extends beyond the second support bracket 2, thereby enabling the third auxiliary support seat 7 to effectively contact and support the steel component.

[0037] In this embodiment, the drilling device 44 includes a second drilling lifting seat 441, a drilling motor 442, a drill bit 444, and a sixth driving member 443. The second drilling lifting seat 441 is disposed on one side of the rotating arm 43. The sixth driving member 443 is used to drive the second drilling lifting seat 441 to slide linearly along the radial axis of the rotating arm 43. The drilling motor 442 is fixed on the second drilling lifting seat 441 and is used to drive the drill bit 444 to rotate. The sixth driving member 443 can be an electric push rod, which is fixed on the rotating arm 43, and its output end is connected to the second drilling lifting seat 441.
