Description

Technical Field

[0001] This utility model relates to the field of door panel processing technology, specifically a drilling device for processing the outer door panel of a driver's cab. Background Technology

[0002] The processing of the exterior door panel of the engineering vehicle driver's cab involves cutting, grinding, drilling, painting, and installation to turn a raw material board into a door panel that meets the specifications.

[0003] The utility model with authorization announcement number CN210704854U discloses a drilling device for processing the outer door panel of the cab of an engineering vehicle, including a robotic arm for adjusting the drilling position, an action component fixedly connected to the end of the robotic arm, and the door panel to be processed is placed on a processing table below the action component.

[0004] As shown in the above utility model, existing drilling devices adjust the drilling position using a robotic arm and clamp the door panel using a pressing component. The installation and placement of the door panel is simple and quick, requiring no special clamps for fixation. However, traditional drilling devices rely on a ventilation component to directly collect waste materials, but the crushing chamber only uses a pre-filter plate for screening, which easily clogs the air duct. Furthermore, drilling position adjustment relies on manual alignment of the robotic arm, limiting positioning accuracy to manual operation. Moreover, the drilling machine lacks a positioning device, making it prone to drill bit deviation due to vibration, resulting in hole diameter deviation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling device for processing the outer door panel of a driver's cab, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for processing the outer door panel of a driver's cab, comprising:

[0007] The mounting frame is equipped with a bidirectional adjustable guide rail on its top, which is used to drive the drilling mechanism to adjust its position.

[0008] A placement plate, which is installed on the lower inner side of the mounting frame, is used to place the outer door panel;

[0009] A clamping member is mounted on a mounting frame and disposed on a placement plate. Two clamping members cooperate to clamp and limit the outer door panel.

[0010] A drilling mechanism, which is mounted on a bidirectional adjustable guide rail on a mounting frame, is used to drill holes in the outer door panel.

[0011] Preferably, the clamping component includes a telescopic cylinder fixed at the middle of both ends of the mounting frame. The output end of the telescopic cylinder is connected to a clamping plate. Guide rods are fixed at both ends of one side of the clamping plate. The mounting frame has guide grooves corresponding to the guide rods. The guide rods and guide grooves are connected through each other.

[0012] Preferably, the drilling mechanism includes a mounting column, the top of which is fixed with a connecting plate by a reinforcing plate. The connecting plate is connected to the movable end of a bidirectional adjusting guide rail. A drilling machine is provided on one side of the mounting column, and the drilling machine is moved up and down by an adjusting component on one side of the mounting column.

[0013] Preferably, a rack is fixed to one side of the mounting column by bolts, and a limit sleeve is provided at the lower end of the rack. The limit sleeve is sleeved on the mounting column by fastening bolts, and the limit sleeve is installed at one end of the drilling machine.

[0014] Preferably, the drilling machine is provided with heat dissipation grooves on both sides, and connecting sleeves are fixed on both the upper and lower sides of one end of the drilling machine. The connecting sleeves are sleeved on the outside of the mounting column, and the bottom end of the drilling machine is connected to a drill bit mounting sleeve through a motor.

[0016] This utility model provides a drilling device for processing the outer door panel of a driver's cab. Compared with the prior art, it has the following advantages:

[0017] 1. The drilling device for processing the outer door panel of the cab achieves three-dimensional precise positioning of the drilling machine in the horizontal and vertical directions through bidirectional adjustable guide rail and gear rack transmission, reducing positioning error. The limit sleeve and fastening bolt cooperate to effectively prevent the drilling machine from moving downward due to vibration, ensuring the consistency of hole diameter, and is especially suitable for high-precision hole processing.

[0018] 2. The drilling device for processing the outer door panel of the cab uses a telescopic cylinder-driven clamping plate with a guide rod-guide groove structure. This ensures uniform and stable clamping force, reducing lateral displacement during drilling compared to traditional clamping plates and ensuring hole accuracy is not affected by clamping wobbling. The drilling machine's side cooling slots, combined with the motor's built-in cooling design, keep the motor temperature rise below 40℃ during continuous operation, preventing speed reduction and motor burnout due to overheating.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides two technical solutions:

[0026] First embodiment: A drilling device for processing the outer door panel of a driver's cab, including a mounting frame 1, a placement plate 2, a clamping member 3 and a drilling mechanism 4.

[0027] Specifically, the top of the mounting frame 1 is provided with a bidirectional adjustable guide rail 11, which is used to drive the drilling mechanism 4 to adjust its position. The placement plate 2 is installed on the lower inner side of the mounting frame 1 for placing the outer door panel. The clamping member 3 is installed on the mounting frame 1 and is set on the placement plate 2. The two clamping members 3 cooperate to clamp and limit the outer door panel. The clamping member 3 includes a telescopic cylinder 31 fixed in the middle of both ends of the mounting frame 1. The output end of the telescopic cylinder 31 is connected to a clamping plate 32. Guide rods 33 are fixed at both ends of one side of the clamping plate 32. The mounting frame 1 is provided with a guide groove 34 corresponding to the guide rod 33. The guide rod 33 and the guide groove 34 are connected through each other.

[0028] The second embodiment differs from the first embodiment in that: the drilling mechanism 4 is mounted on the bidirectional adjustable guide rail 11 on the mounting frame 1, and is used to drill holes in the outer door panel. The drilling mechanism 4 includes a mounting column 41, and a connecting plate 42 is fixed to the top of the mounting column 41 by a reinforcing plate. The connecting plate 42 is connected to the movable end of the bidirectional adjustable guide rail 11, so that the bidirectional adjustable guide rail 11 can drive the mounting column 41 to move in two horizontal directions. A drilling machine 43 is provided on one side of the mounting column 41. The drilling machine 43 is moved up and down by an adjusting component 44 on one side of the mounting column 41. A rack 411 is fixed to one side of the mounting column 41 by bolts. A limit sleeve 431 is provided at the lower end of the rack 411. The limit sleeve 431 is sleeved on the mounting column 41 by fastening bolts. The limit sleeve 431 is installed at one end of the drilling machine 43 to prevent the drilling machine 43 from moving. 3. Move downwards until separated from the mounting post 41. Both sides of the drilling machine 43 are provided with heat dissipation grooves for rapid heat dissipation of the motor inside the drilling machine 43. One end of the drilling machine 43 is fixed with connecting sleeves 432 on both the upper and lower sides. The connecting sleeves 432 are sleeved on the outside of the mounting post 41. The bottom end of the drilling machine 43 is connected to the drill bit mounting sleeve 433 through the motor. The drill bit 434 is mounted on the drill bit mounting sleeve 433. The adjusting component 44 includes a handwheel 441 that is movably mounted on the upper side of one side of the drilling machine 43 through a connecting shaft. One end of the connecting shaft is fixed with a gear 442. The gear 442 meshes with the rack 411. By rotating the handwheel 441, the handwheel 441 drives the gear 442 to rotate through the connecting shaft. The gear 442 and the rack 411 cooperate to drive the drilling machine 43 to move downwards until the drill bit 434 on the drilling machine 43 drills a hole in the outer door panel.

[0029] When this device is in operation, the outer door panel is first placed on the placement plate 2. Then, the telescopic cylinder 31 is activated, which moves the clamping plate 32 until the two clamping plates 32 cooperate to clamp and limit the outer door panel. Next, the bidirectional adjusting guide rail 11 is activated, which moves the drilling mechanism 4 in two horizontal directions until the drilling mechanism 4 moves above the drilling position of the outer door panel. At this time, the drilling machine 43 is activated, and the handwheel 441 is turned at the same time. The handwheel 441 drives the gear 442 to rotate through the connecting shaft. The gear 442 cooperates with the rack 411 to drive the drilling machine 43 downward. Move the drill 43 until the drill bit 434 on the drill 43 drills a hole in the outer door panel. After drilling is completed, turn the handwheel 441 in the opposite direction to move the drill 43 upward until the drill bit 434 separates from the outer door panel. At this time, turn the handle on the limit sleeve 431. The handle drives the bolt to tighten the limit sleeve 431, so that the limit sleeve 431 fits tightly with the mounting post 41, which plays a damping and limiting role, limiting the drill 43 at the corresponding height and preventing the drill 43 from moving downward. Then, move the drill 43 to another place on the outer door panel that needs to be drilled through the bidirectional adjustment guide rail 11.
