Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and in particular to an aluminum plate drilling device. Background Technology

[0002] Aluminum sheet refers to rectangular plates rolled from aluminum ingots. It is classified into pure aluminum sheets, alloy aluminum sheets, thin aluminum sheets, medium-thick aluminum sheets, and patterned aluminum sheets. Aluminum sheets are typically categorized by alloy composition and thickness. Based on alloy composition, they can be divided into high-purity aluminum sheets, pure aluminum sheets, alloy aluminum sheets, composite aluminum sheets, welded sheets, and clad aluminum sheets. Based on thickness, they can be divided into thin sheets, standard sheets, medium sheets, and thick sheets. The production and processing of aluminum sheets involves cutting, welding, and drilling.

[0003] In the prior art, such as the patent application number CN202222871591.2, an aluminum plate drilling device is disclosed, including a mounting box and a drilling motor. The drilling motor is located above the mounting box, and an adjustment mechanism is installed between the mounting box and the drilling motor. The adjustment mechanism includes a servo motor, a screw, a support column, a first electric telescopic rod, and a second electric telescopic rod. A rotating mechanism is installed on the top of the mounting box. In this utility model, the screw rotates with the drive end of the servo motor and moves the support column longitudinally on the mounting box through a limiting groove. By setting the first and second electric telescopic rods, it is convenient to move the drilling motor laterally and adjust the drilling depth of the drill bit on the drilling motor. This facilitates the adjustment of the drilling position of the drill bit on the aluminum plate to meet different production needs. Moreover, it eliminates the need for manual movement of the aluminum plate, avoiding safety accidents such as hand injuries, while also avoiding wasted manpower and improving processing efficiency.

[0004] The above-mentioned device has the following limitations when actually drilling holes:

[0005] Firstly, during the drilling operation, the aluminum plate is placed directly on the top surface of the turntable. However, there are no holes on the turntable to allow the drill bit to pass through. Therefore, every time the drill bit drills a hole in the aluminum plate, it will damage the turntable.

[0006] Secondly, the aforementioned device lacks a limiting device for the aluminum plate, which makes it prone to displacement of the aluminum plate during drilling, leading to drilling failure. Utility Model Content

[0007] The purpose of this utility model is to provide an aluminum plate drilling device that can prevent the drill bit of the drilling machine from damaging the turntable, and at the same time, can limit the aluminum plate to ensure that the drilling operation is carried out smoothly.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] An aluminum plate drilling device includes a worktable, a placement cavity disposed on the top surface of the worktable, a turntable rotatably disposed in the placement cavity, a driving assembly for driving the turntable to rotate, and a drilling assembly and a limiting assembly disposed on the top of the worktable; the turntable includes an annular frame, a connecting plate disposed in the middle of the annular frame, and multiple placement rods disposed between the annular frame and the connecting plate; the limiting assembly includes at least two first vertical rods disposed on the top of the worktable and near the turntable, a connecting portion disposed at the top of each first vertical rod, a first hydraulic rod disposed at the bottom end of the connecting portion, and a pressure plate disposed at the telescopic end of the first hydraulic rod.

[0010] Preferably, the connecting part includes a second hydraulic rod disposed on the side wall of the first vertical rod, and a connecting block disposed on the telescopic end of the second hydraulic rod, wherein the first hydraulic rod is disposed at the bottom end of the connecting block.

[0011] Preferably, the drive assembly includes a protective shell disposed within the placement cavity, a motor disposed within the protective shell, and the output end of the motor being connected to the center of the bottom wall of the connecting plate.

[0012] Preferably, a cross-shaped mounting bracket is provided inside the placement cavity, and the protective shell is mounted on the cross-shaped mounting bracket.

[0013] Preferably, the side wall of the placement cavity is provided with a waste collection channel communicating with the placement cavity.

[0014] Preferably, the bottom wall of the placement cavity is inclined downward along the direction of the waste collection channel.

[0015] Preferably, the drilling assembly includes a second vertical rod disposed at the top of the workbench, a horizontal rod disposed at the top of the second vertical rod, a third hydraulic rod disposed at the bottom of the horizontal rod, and a drilling machine disposed at the bottom of the third hydraulic rod.

[0016] Preferably, the outer wall of the drilling machine is provided with a sliding rod, and the side wall of the second vertical rod is provided with a vertical sliding groove, and the end of the sliding rod away from the drilling machine is slidably connected to the vertical sliding groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] By defining the turntable as including an annular frame, a connecting plate disposed in the middle of the annular frame, and multiple placement rods disposed between the annular frame and the connecting plate, multiple holes can be formed in the turntable through which the drill bit of the drilling machine can pass, ensuring that the drill bit will not damage the turntable structure during drilling operations.

[0020] By setting up a limiting assembly including a first vertical rod, a connecting part, a first hydraulic rod, and a pressure plate, the pressure plate can be moved downward by activating the first hydraulic rod during drilling operations to apply a vertically downward force to the aluminum plate, thereby limiting the aluminum plate to the turntable, ensuring that the aluminum plate will not be displaced during drilling operations, and ensuring that drilling operations can proceed smoothly.

Detailed Implementation

[0025] Example 1

[0026] An aluminum plate drilling device, such as Figure 1-3 As shown, it includes a worktable 1, a placement cavity 2 disposed on the top surface of the worktable 1, a turntable rotatably disposed within the placement cavity 2, a drive assembly for driving the turntable to rotate, and a drilling assembly and a limiting assembly disposed on the top of the worktable 1; as shown. Figure 1-3As shown, the turntable includes an annular frame 4 rotatably connected to the inner wall of the placement cavity 2, a connecting plate disposed in the middle of the annular frame 4, and multiple placement rods 5 disposed between the annular frame 4 and the connecting plate (wherein, the top surfaces of the connecting plate, placement rods 5, and annular frame 4 are all flush). The limiting assembly includes at least two first vertical rods 6 disposed at the top of the worktable 1 and near the turntable, a connecting portion disposed at the top of each first vertical rod 6, a first hydraulic rod 7 disposed at the bottom end of the connecting portion, and a pressure plate 8 disposed at the telescopic end of the first hydraulic rod 7. Further, the connecting portion includes a second hydraulic rod 9 disposed on the side wall of the first vertical rod 6, and a connecting block disposed at the telescopic end of the second hydraulic rod 9, with the first hydraulic rod 7 disposed at the bottom end of the connecting block. Further, the driving assembly includes a protective shell 10 disposed within the placement cavity 2, a motor disposed within the protective shell 10, and the output end of the motor being connected to the center of the bottom wall of the connecting plate. Furthermore, the drilling assembly includes a second vertical rod 13 disposed at the top of the workbench 1, a horizontal rod 14 disposed at the top of the second vertical rod 13, a third hydraulic rod 15 disposed at the bottom of the horizontal rod 14, and a drilling machine 16 disposed at the bottom of the third hydraulic rod 15. Further, as... Figure 1-3 As shown, the outer wall of the drilling machine 16 is provided with a sliding rod 17 (e.g., Figure 1 As shown, the slide rod 17 is mounted on the drive motor in the drilling machine 16. The side wall of the second vertical rod 13 is provided with a vertical slide groove 18. The end of the slide rod 17 away from the drilling machine 16 is slidably connected to the vertical slide groove 18 to ensure that the drilling machine 16 always moves in the vertical direction.

[0027] Working principle: The aluminum plate to be drilled (not shown in the figure) is placed horizontally on the top surface of the turntable. Then, depending on the size of the aluminum plate, the second hydraulic rod 9 is activated to adjust the horizontal position of the pressure plate 8, ensuring that the pressure plate 8 can squeeze the area of ​​the aluminum plate near the edge. Next, the first hydraulic rod 7 is activated, causing the pressure plate 8 to move downwards until a certain degree of compressive force is applied to the aluminum plate, thus limiting its movement. Then, the third hydraulic rod 15 is activated, causing the drilling machine 16 (drilling machine 16 is existing technology, and its structure and working principle will not be described in detail here) to move downwards to drill a hole in the aluminum plate. During drilling, it is necessary to ensure that the drilling area is not directly above the placement rod 5. If the drilling position needs to be adjusted, it can be achieved by rotating the turntable or moving the position of the aluminum plate on the turntable. Both methods can be used to release the limiting device from limiting the aluminum plate as needed. The method of adjusting the drilling area of ​​the aluminum plate by rotating the turntable is as follows: start the motor, and under the action of the motor, the turntable rotates in the placement cavity 2, thereby causing the aluminum plate on the top surface to rotate. When the area to be drilled rotates to the position directly below the drilling machine, turn off the motor, and then start the third hydraulic rod 15 and the drilling machine 16.

[0028] Example 2

[0029] In Example 1, during drilling operations, waste chips are generated. These chips fall into the placement cavity 2 along the gaps between the placement rods 5. To collect these waste chips, based on Example 1, as follows... Figure 1-2 As shown, a cross-shaped mounting bracket 11 is provided inside the placement cavity 2, and the protective shell 10 is mounted on the cross-shaped mounting bracket 11. This allows for a certain gap between the bottom end of the protective shell 10 and the bottom wall of the placement cavity 2, facilitating the collection of waste debris from the bottom wall of the placement cavity 2. Furthermore, as... Figure 1 As shown, the side wall of the placement cavity 2 is provided with a waste collection channel 12 communicating with the placement cavity 2. Furthermore, the bottom wall of the placement cavity 2 is inclined downwards along the direction of the waste collection channel 12, and the bottom wall of the collection channel and the bottom wall of the placement cavity 2 are both on the same inclined surface, so that the waste in the placement cavity 2 can be automatically discharged along the inclined surface. In actual implementation, the waste cannot be fully discharged automatically. To ensure smooth discharge, tools such as scrapers with handles can be used to scrape it out. When using a scraper, simply insert the scraper into the placement cavity 2 to scrape out the waste.

[0030] Furthermore, the bottom end of the second vertical rod 13 is provided with at least two sliders (existing technology, not shown in the figure) to ensure smooth movement of the second vertical rod 13. The bottom end of the worktable 1 is provided with a horizontal groove 20 that slides with the sliders, and the top end of the worktable 1 is provided with a fourth hydraulic rod 21, the telescopic end of which is connected to the second vertical rod 13. By setting the sliders and the horizontal groove 20, the distance between the vertical rod and the placement cavity 2 can be adjusted, thereby increasing the drilling area of ​​the drilling assembly. By setting the fourth hydraulic rod 21, the drilling assembly can be driven to move back and forth along the direction of the horizontal groove 20.
