Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing equipment, specifically to a double-sided drilling machine tool for sheet metal. Background Technology

[0002] When processing sheet metal, holes need to be machined on both the top and bottom surfaces. Typically, the holes on the top surface are machined first, then the sheet is flipped over to machine the holes on the bottom surface. This method reduces processing efficiency because it requires flipping the sheet mid-process. Therefore, processing equipment capable of machining both the top and bottom surfaces of the sheet metal simultaneously has been developed.

[0003] For example, patent CN220576188U discloses a "Double-Sided Hole Grooving Processing Equipment for Furniture Boards." This patent features upper and lower gantry hole grooving processing devices mounted on a frame, allowing simultaneous processing of the upper and lower surfaces of the board without the need to flip the board, thus improving processing efficiency. Furthermore, the patent includes upper and lower telescopic support devices on the frame that clamp the upper and lower surfaces of the board to be processed. These telescopic support devices are linked to the upper and lower gantry hole grooving processing devices; as the upper and lower gantry hole grooving processing devices move back and forth, the upper and lower telescopic support devices extend and retract accordingly to maintain the support area for the upper and lower surfaces of the board to be processed.

[0004] In the aforementioned patent, because the upper and lower plate telescopic support devices clamp the upper and lower surfaces of the plate, the plate needs to be horizontally inserted between the upper and lower plate telescopic support devices when placing the plate, which increases the difficulty of placing the plate.

[0005] Therefore, how to facilitate the placement of the boards is a technical problem that needs to be solved. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this invention proposes a double-sided drilling machine for sheet metal, which facilitates the placement of sheet metal.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A double-sided drilling machine for sheet metal includes a frame with a window in the middle. An upper hole processing device is located above the window, and a lower hole processing device is located below the window. Both the upper and lower hole processing devices include a transverse movement mechanism, a vertical movement mechanism is provided on the transverse movement mechanism, and a drilling mechanism is provided on the vertical movement mechanism. A first roller mechanism is located on the front side of the window, and a second roller mechanism is located on the rear side of the window. Both the first and second roller mechanisms include multiple rollers distributed longitudinally. A longitudinal movement device is located on one side of the top surface of the frame, and a clamping device is provided on the longitudinal movement device.

[0009] Furthermore, the longitudinal moving device includes a longitudinal rail, a longitudinal rack, a longitudinal support, a longitudinal gear, and a longitudinal motor. The longitudinal rail and the longitudinal rack are both located on the top surface of the frame. The longitudinal support is slidably connected to the longitudinal rail. The longitudinal support is equipped with a longitudinal gear and a longitudinal motor for driving the longitudinal gear to rotate. The longitudinal gear cooperates with the longitudinal rack.

[0010] Furthermore, the clamping device includes a clamping fixed seat, a clamping movable seat, and a clamping lifting rod. The clamping fixed seat is located on the top surface of the longitudinal support, and the clamping movable seat is located above the clamping fixed seat. The clamping movable seat is connected to the clamping fixed seat through the clamping lifting rod.

[0011] Furthermore, a first pressing mechanism is provided above the first roller mechanism, and a second pressing mechanism is provided above the second roller mechanism. Both the first pressing mechanism and the second pressing mechanism include a pressing gantry, a pressing support, a pressing plate, and a pressing lifting rod. The pressing gantry is located on the top surface of the frame, and the pressing gantry is provided with multiple pressing supports along the transverse direction. The pressing supports are provided with a pressing plate and a pressing lifting rod for driving the pressing plate to rise and fall.

[0012] Furthermore, a pressing wheel is rotatably connected to the side of the pressing plate.

[0013] Furthermore, the upper hole processing device is provided on the pressing gantry in the second pressing mechanism.

[0014] Furthermore, the frame is provided with a pushing device on the side away from the longitudinal moving device. The pushing device includes a pushing bracket, a pushing plate, and a pushing telescopic rod. The pushing bracket is located on the top of the frame and is provided with a pushing plate and a pushing telescopic rod for driving the pushing plate to move laterally.

[0015] The beneficial effects of this utility model are:

[0016] 1. Compared with the prior art, the present invention does not have an upper plate telescopic support device to block the plate when placing it. The plate can be placed directly from top to bottom on the first roller mechanism without being blocked by other structures, making it more convenient to place.

[0017] 2. By placing the boards from top to bottom, compared with inserting the boards longitudinally in the prior art, the longitudinal length of the production line can be shortened, saving space and improving space utilization.

[0018] 3. Since there is no telescopic support device above the board to obstruct the view, it is easier to observe the processing status of the board surface and facilitate quality inspection during the processing.

[0019] 4. When drilling holes in the sheet metal, the first pressing mechanism is used to press the sheet metal located on the first roller mechanism, and the second pressing mechanism is used to press the sheet metal located on the second roller mechanism, which can prevent the sheet metal from warping and maintain the stability of the sheet metal.

[0020] 5. Compared to pressing the sheet material directly with a pressing plate, the contact area between the pressing roller and the sheet material is smaller. The pressing roller has no sharp edges that could scratch the sheet material, thus improving protection. Furthermore, the pressing roller does not impede the longitudinal movement of the sheet material, ensuring its stability during longitudinal movement.

[0021] 6. The push device allows the left side of the sheet metal to be pushed between the clamping movable seat and the clamping fixed seat of the clamping device, eliminating the need for manual pushing by workers and saving manpower. Attached Figure Description

It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] Example:

[0051] See Figures 1 to 10 A double-sided drilling machine for sheet metal includes a frame 1, with a window 11 in the middle of the frame 1.

[0052] See Figure 1 and Figure 3 A first roller mechanism 2a is provided on the front side of window 11, and a second roller mechanism 2b is provided on the rear side of window 11. Both the first roller mechanism 2a and the second roller mechanism 2b include multiple rollers distributed longitudinally. Longitudinal refers to the straight line direction from front to back. For easy distinction, the rollers in the first roller mechanism 2a are referred to as the first roller 2a1, and the rollers in the second roller mechanism 2b are referred to as the second roller 2b1. The left and right ends of the first roller 2a1 and the left and right ends of the second roller 2b1 are rotatably connected to the frame 1.

[0053] When the sheet material is conveyed on the first roller mechanism 2a, the resistance to conveying the sheet material is reduced because the left and right ends of the first roller 2a1 are rotatably connected to the frame 1. Similarly, when the sheet material is conveyed on the second roller mechanism 2b, the resistance to conveying the sheet material is also reduced because the left and right ends of the second roller 2b1 are rotatably connected to the frame 1.

[0054] See Figure 1 , Figure 2 and Figure 9 A first pressing mechanism 3a is provided above the first roller mechanism 2a, and a second pressing mechanism 3b is provided above the second roller mechanism 2b. When drilling holes in the sheet metal, the first pressing mechanism 3a is used to press the sheet metal located on the first roller mechanism 2a, and the second pressing mechanism 3b is used to press the sheet metal located on the second roller mechanism 2b, which can prevent the sheet metal from warping and maintain the stability of the sheet metal.

[0055] See Figure 2 and Figure 9Both the first pressing mechanism 3a and the second pressing mechanism 3b include a pressing gantry, a pressing support, a pressing plate, and a pressing lifting rod. For ease of distinction, the pressing gantry, pressing support, pressing plate, and pressing lifting rod in the first pressing mechanism 3a are respectively designated as the first pressing gantry 3a1, the first pressing support 3a2, the first pressing plate 3a3, and the first pressing lifting rod 3a4; the pressing gantry, pressing support, pressing plate, and pressing lifting rod in the second pressing mechanism 3b are respectively designated as the second pressing gantry 3b1, the second pressing support 3b2, the second pressing plate 3b3, and the second pressing lifting rod 3b4.

[0056] See Figure 2 For the first pressing mechanism 3a, the first pressing gantry 3a1 is fixedly installed on the top surface of the frame 1. The first pressing gantry 3a1 is located in front of the window 11. Multiple first pressing brackets 3a2 are fixedly installed on the first pressing gantry 3a1 in the horizontal direction. A first pressing lifting rod 3a4 is fixedly installed on the first pressing bracket 3a2. The first pressing lifting rod 3a4 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The piston rod of the first pressing lifting rod 3a4 is set downward. A first pressing plate 3a3 is fixedly installed on the piston rod of the first pressing lifting rod 3a4.

[0057] The working principle of the first pressing mechanism 3a is as follows: When the piston rod of the first pressing lifting rod 3a4 extends downward, it pushes the first pressing plate 3a3 downward, pressing the sheet material. When the piston rod of the first pressing lifting rod 3a4 retracts upward, it drives the first pressing plate 3a3 upward, moving it away from the sheet material. By adjusting the extension length of the piston rod of the first pressing lifting rod 3a4, the first pressing plate 3a3 can press sheets of different thicknesses.

[0058] See Figure 9 For the second pressing mechanism 3b, the second pressing gantry 3b1 is fixedly installed on the top surface of the frame 1. The second pressing gantry 3b1 is located on the rear side of the window 11. Multiple second pressing brackets 3b2 are fixedly installed on the second pressing gantry 3b1 in the horizontal direction. A second pressing lifting rod 3b4 is fixedly installed on the second pressing bracket 3b2. The second pressing lifting rod 3b4 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The piston rod of the second pressing lifting rod 3b4 is set downward. A second pressing plate 3b3 is fixedly installed on the piston rod of the second pressing lifting rod 3b4.

[0059] The working principle of the second pressing mechanism 3b is as follows: When the piston rod of the second pressing lifting rod 3b4 extends downward, it pushes the second pressing plate 3b3 downward, pressing the sheet material. When the piston rod of the second pressing lifting rod 3b4 retracts upward, it drives the second pressing plate 3b3 upward, moving it away from the sheet material. By adjusting the extension length of the piston rod of the second pressing lifting rod 3b4, the second pressing plate 3b3 can press sheets of different thicknesses.

[0060] Furthermore, a pressure roller is rotatably connected to the side of the pressing plate. When pressing the sheet material, the pressure roller presses against the sheet material. Compared to the pressing plate directly pressing the sheet material, the contact area between the pressure roller and the sheet material is smaller, and the pressure roller has no sharp edges that could scratch the sheet material, thus improving the protection of the sheet material. For easy distinction, see [link to relevant documentation]. Figure 2 The pressing wheel located on the side of the first pressing plate 3a3 is designated as the first pressing wheel 3a31; see also Figure 9 The pressing wheel located on the side of the second pressing plate 3b3 is designated as the second pressing wheel 3b31.

[0061] Furthermore, when the first pressing roller 3a31 and the second pressing roller 3b31 press against the upper surface of the board, because the first pressing roller 3a31 is rotatably connected to the side of the first pressing plate 3a3 and the second pressing roller 3b31 is rotatably connected to the side of the second pressing plate 3b3, when the longitudinal moving mechanism 5 drives the board to move longitudinally, both the first pressing roller 3a31 and the second pressing roller 3b31 will rotate relative to the board. The first pressing roller 3a31 and the second pressing roller 3b31 will not hinder the longitudinal movement of the board. Moreover, because of the pressing of the first pressing roller 3a31 and the second pressing roller 3b31, the board can remain stable during longitudinal movement, preventing the board from moving up and down and also preventing the board from warping.

[0062] See Figure 1 A hole-making device 4a is provided above window 11; see also Figure 8 A lower hole processing device 4b is provided below window 11. The upper hole processing device 4a is used to process holes on the upper surface of the plate, and the lower hole processing device 4b is used to process holes on the lower surface of the plate.

[0063] See Figure 9 and Figure 7 Both the upper hole processing device 4a and the lower hole processing device 4b include a horizontal movement mechanism, a vertical movement mechanism, and a drilling mechanism. For ease of distinction, the horizontal movement mechanism, vertical movement mechanism, and drilling mechanism in the upper hole processing device 4a are respectively referred to as the upper horizontal movement mechanism 4a1, the upper vertical movement mechanism 4a2, and the upper drilling mechanism 4a3; the horizontal movement mechanism, vertical movement mechanism, and drilling mechanism in the lower hole processing device 4b are respectively referred to as the lower horizontal movement mechanism 4b1, the lower vertical movement mechanism 4b2, and the lower drilling mechanism 4b3.

[0064] See Figure 9 For the upper hole processing device 4a, the upper transverse movement mechanism 4a1 is mounted on the second pressing gantry 3b1, the upper vertical movement mechanism 4a2 is mounted on the upper transverse movement mechanism 4a1, and the upper drilling mechanism 4a3 is mounted on the upper vertical movement mechanism 4a2. The upper transverse movement mechanism 4a1 is used to drive the upper vertical movement mechanism 4a2 to move laterally (lateral refers to the left-right straight direction), and the upper vertical movement mechanism 4a2 is used to drive the upper drilling mechanism 4a3 to move vertically. The upper drilling mechanism 4a3 is used to process holes on the upper surface of the plate.

[0065] For details, see Figure 9 The upper transverse movement mechanism 4a1 includes a crossbeam 4a11, an upper transverse movement slide rail 4a12, an upper transverse movement rack 4a13, an upper transverse movement bracket 4a14, an upper transverse movement motor 4a15, and an upper transverse movement gear 4a16. The crossbeam 4a11 is fixedly installed on the top of the second pressing gantry 3b1. The upper transverse movement slide rail 4a12 is fixedly installed on the front side of the crossbeam 4a11. The upper transverse movement rack 4a13 is fixedly installed on the top surface of the crossbeam 4a11. The upper transverse movement bracket 4a14 slides laterally with the upper transverse movement slide rail 4a12. The upper transverse movement motor 4a15 is fixedly installed on the rear side of the upper transverse movement bracket 4a14. The upper transverse movement motor 4a15 is a servo motor. The upper transverse movement gear 4a16 is fixedly installed on the output shaft of the upper transverse movement motor 4a15, and the upper transverse movement gear 4a16 meshes with the upper transverse movement rack 4a13.

[0066] The working principle of the upper transverse mechanism 4a1 is as follows: When the upper transverse motor 4a15 drives the upper transverse gear 4a16 to rotate forward, the upper transverse gear 4a16 drives the upper transverse support 4a14 to move from left to right; conversely, when the upper transverse motor 4a15 drives the upper transverse gear 4a16 to rotate in reverse, the upper transverse gear 4a16 drives the upper transverse support 4a14 to move from right to left.

[0067] See Figure 9The upper vertical movement mechanism 4a2 includes a first upper vertical movement slide rail 4a21, a first upper vertical movement cylinder 4a22, a first upper vertical movement bracket 4a23, a second upper vertical movement slide rail 4a24, a second upper vertical movement cylinder 4a25, and a second upper vertical movement bracket 4a26. The first upper vertical movement slide rail 4a21 is fixedly installed on the front side of the upper horizontal movement bracket 4a14, and the first upper vertical movement cylinder 4a22 is fixedly installed on the top of the upper horizontal movement bracket 4a14. The piston rod of the first upper vertical movement cylinder 4a22 is set downward, and the first upper vertical movement bracket 4a23 is fixedly installed on the piston rod of the first upper vertical movement cylinder 4a22. The first upper vertical movement bracket 4a23 slides in cooperation with the first upper vertical movement slide rail 4a21 in the vertical direction. The second upper vertical slide rail 4a24 is fixedly installed on the front side of the first upper vertical support 4a23. The second upper vertical cylinder 4a25 is fixedly installed on the top of the first upper vertical support 4a23. The piston rod of the second upper vertical cylinder 4a25 is set downward. The second upper vertical support 4a26 is fixedly installed on the piston rod of the second upper vertical cylinder 4a25. The second upper vertical support 4a26 slides in cooperation with the second upper vertical slide rail 4a24 in the vertical direction.

[0068] The working principle of the upper vertical movement mechanism 4a2 is as follows: When the piston rod of the first upper vertical movement cylinder 4a22 extends downward, it pushes the first upper vertical movement bracket 4a23 downward; when the piston rod of the second upper vertical movement cylinder 4a25 extends downward, it pushes the second upper vertical movement bracket 4a26 downward. In this embodiment, the upper vertical movement mechanism 4a2, by setting the first upper vertical movement cylinder 4a22 and the second upper vertical movement cylinder 4a25, can increase the vertical stroke.

[0069] See Figure 9 The upper drilling mechanism 4a3 includes an upper drilling motor 4a31 and an upper drill bit 4a32. The upper drilling motor 4a31 can be a servo motor. The upper drilling motor 4a31 is fixedly installed on the front side of the second upper vertical moving bracket 4a26. The output shaft of the upper drilling motor 4a31 is set downward, and the upper drill bit 4a32 is fixedly installed on the output shaft of the upper drilling motor 4a31.

[0070] The working principle of the upper drilling mechanism 4a3 is as follows: When the upper drilling motor 4a31 starts, it drives the upper drill bit 4a32 to rotate. When the upper vertical movement mechanism 4a2 drives the upper drilling motor 4a31 to move downward, the rotating lower drill bit 4b32 feeds towards the upper surface of the plate to process the hole. The greater the downward displacement of the upper vertical movement mechanism 4a2 driving the upper drilling motor 4a31, the greater the drilling depth. When the upper vertical movement mechanism 4a2 drives the upper drilling motor 4a31 to move upward, the upper drilling motor 4a31 drives the upper drill bit 4a32 to gradually withdraw from the processed hole.

[0071] See Figure 7For the hole-making device 4b, a lower horizontal movement mechanism 4b1 is installed at the bottom of the frame 1, a lower vertical movement mechanism 4b2 is installed on the lower horizontal movement mechanism 4b1, and a lower drilling mechanism 4b3 is installed on the lower vertical movement mechanism 4b2. The lower horizontal movement mechanism 4b1 drives the lower vertical movement mechanism 4b2 to move laterally, the lower vertical movement mechanism 4b2 drives the lower drilling mechanism 4b3 to move vertically, and the lower drilling mechanism 4b3 is used to process holes on the lower surface of the plate.

[0072] For details, see Figure 7 The lower transverse mechanism 4b1 includes a lower transverse slide rail 4b11, a lower transverse rack 4b12, a lower transverse support 4b13, a lower transverse motor 4b14, and a lower transverse gear 4b15. The lower transverse slide rail 4b11 and the lower transverse rack 4b12 are both fixedly installed at the bottom of the frame 1. The lower transverse support 4b13 slides laterally with the lower transverse slide rail 4b11. The lower transverse motor 4b14, which is a servo motor, is fixedly installed on the output shaft of the lower transverse motor 4b14, and the lower transverse gear 4b15 meshes with the lower transverse rack 4b12.

[0073] The working principle of the lower transverse mechanism 4b1 is as follows: When the lower transverse motor 4b14 drives the lower transverse gear 4b15 to rotate forward, the lower transverse gear 4b15 drives the lower transverse support 4b13 to move from left to right; conversely, when the lower transverse motor 4b14 drives the lower transverse gear 4b15 to rotate in reverse, the lower transverse gear 4b15 drives the lower transverse support 4b13 to move from right to left.

[0074] See Figure 7 The lower vertical movement mechanism 4b2 includes a lower vertical movement slide rail 4b21, a lower vertical movement cylinder 4b22, and a lower vertical movement bracket 4b23. The lower vertical movement slide rail 4b21 is fixedly installed on the front side of the lower horizontal movement bracket 4b13, and the lower vertical movement cylinder 4b22 is fixedly installed on the bottom of the lower horizontal movement bracket 4b13. The piston rod of the lower vertical movement cylinder 4b22 is set upward, and the lower vertical movement bracket 4b23 is fixedly installed on the piston rod of the lower vertical movement cylinder 4b22. The lower vertical movement bracket 4b23 slides in cooperation with the lower vertical movement slide rail 4b21 in the vertical direction.

[0075] The working principle of the lower vertical movement mechanism 4b2 is as follows: when the piston rod of the lower vertical movement cylinder 4b22 extends upward, the piston rod of the lower vertical movement cylinder 4b22 pushes the lower vertical movement bracket 4b23 to move upward.

[0076] See Figure 7The lower drilling mechanism 4b3 includes a lower drilling motor 4b31 and a lower drill bit 4b32. The lower drilling motor 4b31 can be a servo motor. The lower drilling motor 4b31 is fixedly installed on the front side of the lower vertical movement bracket 4b23. The output shaft of the lower drilling motor 4b31 is set upward, and the lower drill bit 4b32 is fixedly installed on the output shaft of the lower drilling motor 4b31.

[0077] The working principle of the lower drilling mechanism 4b3 is as follows: After the lower drilling motor 4b31 starts, it drives the lower drill bit 4b32 to rotate. When the lower vertical movement mechanism 4b2 drives the lower drilling motor 4b31 to move upward, the rotating lower drill bit 4b32 feeds towards the lower surface of the plate to process the hole. The greater the upward displacement of the lower vertical movement mechanism 4b2 driving the lower drilling motor 4b31, the greater the drilling depth. When the lower vertical movement mechanism 4b2 drives the lower drilling motor 4b31 to move downward, the lower drilling motor 4b31 drives the lower drill bit 4b32 to gradually exit the processed hole.

[0078] See Figure 3 and Figure 4 A longitudinal moving device 5 is provided on the top left side of the frame 1, and a clamping device 6 is provided on the longitudinal moving device 5. The clamping device 6 is used to clamp the plate, and the longitudinal moving device 5 is used to drive the clamping device 6 holding the plate to move longitudinally, so that the plate passes through the first roller 2a1, window 11 and second roller 2b1 from front to back. When the plate passes through the first roller 2a1 and the second roller 2b1, both the first roller 2a1 and the second roller 2b1 provide support for the plate, and both the first roller 2a1 and the second roller 2b1 can rotate adaptively, which can reduce the frictional resistance between them and the plate, and facilitate the longitudinal transmission of the plate. When the plate passes through the window 11, the upper hole processing device 4a located above the window 11 can process holes on the upper surface of the plate, and the lower hole processing device 4b located below the window 11 can process holes on the lower surface of the plate.

[0079] See Figure 3 and Figure 4 In this embodiment, the longitudinal moving device 5 includes a longitudinal track 51, a longitudinal rack 52, a longitudinal support 53, a longitudinal gear 54, and a longitudinal motor 55. The longitudinal track 51 and the longitudinal rack 52 are both fixedly installed on the left side of the top surface of the frame 1. The longitudinal support 53 slides along the longitudinal direction with the longitudinal track 51. The longitudinal motor 55 is fixedly installed on the top surface of the longitudinal support 53. The longitudinal motor 55 is a servo motor. The output shaft of the longitudinal motor 55 passes downward through the longitudinal support 53. The longitudinal gear 54 is fixedly installed on the output shaft of the longitudinal motor 55. The longitudinal gear 54 meshes with the longitudinal rack 52.

[0080] The working principle of the longitudinal moving device 5 is as follows: When the longitudinal motor 55 drives the longitudinal gear 54 to rotate forward, the longitudinal gear 54 drives the longitudinal support 53 to move from back to front along the longitudinal direction. Conversely, when the longitudinal motor 55 drives the longitudinal gear 54 to rotate in reverse, the longitudinal gear 54 drives the longitudinal support 53 to move from front to back along the longitudinal direction.

[0081] See Figure 3 and Figure 4 In this embodiment, the clamping device 6 includes a clamping fixed seat 61, a clamping movable seat 62, and a clamping lifting rod 63. The clamping fixed seat 61 is fixedly installed on the top surface of the longitudinal support 53, and the clamping lifting rod 63 is also fixedly installed on the top surface of the longitudinal support 53. The clamping lifting rod 63 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The clamping movable seat 62 is fixedly installed on the piston rod of the clamping lifting rod 63, and the clamping movable seat 62 is located above the clamping fixed seat 61.

[0082] The working principle of the clamping device 6 is as follows: When the piston rod of the clamping lifting rod 63 extends upward, the clamping movable seat 62 moves upward, increasing the distance between the clamping movable seat 62 and the clamping fixed seat 61. At this time, a plate can be placed between the clamping movable seat 62 and the clamping fixed seat 61. Conversely, when the piston rod of the clamping lifting rod 63 retracts downward, the clamping movable seat 62 moves downward, decreasing the distance between the clamping movable seat 62 and the clamping fixed seat 61. At this time, the clamping movable seat 62 and the clamping fixed seat 61 can clamp the plate. In addition, by adjusting the extension length of the piston rod of the clamping lifting rod 63, the distance between the clamping movable seat 62 and the clamping fixed seat 61 can be adjusted to clamp plates of different thicknesses. After the clamping device 6 clamps the plate, the longitudinal moving device 5 can move the clamping device 6 holding the plate longitudinally together.

[0083] See Figure 3 and Figure 5 A pushing device 7 is provided on the right side of the top surface of the frame 1. The pushing device 7 can push the plate laterally, allowing the plate to gradually approach the clamping device 6. In this embodiment, the pushing device 7 includes a pushing bracket 71, a pushing plate 72, and a pushing telescopic rod 73. The pushing bracket 71 is fixedly installed on the right side of the top surface of the frame 1, and the pushing telescopic rod 73 is fixedly installed on the pushing bracket 71. The pushing telescopic rod 73 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, and the pushing plate 72 is fixedly installed on the piston rod of the pushing telescopic rod 73.

[0084] The working principle of the pushing device 7 is as follows: When the piston rod of the pushing telescopic rod 73 extends, it drives the pushing plate 72 to move to the left. When the pushing plate 72 moves to the left, it can push the plate closer to the clamping device 6. Conversely, when the piston rod of the pushing telescopic rod 73 retracts, it drives the pushing plate 72 to move to the right. When the pushing plate 72 moves to the right, it gradually moves away from the plate.

[0085] The working principle of this embodiment is as follows:

[0086] (1) The worker manually places the sheet material to be processed onto the first roller mechanism 2a, or the overhead crane is used to lift the sheet material onto the first roller mechanism 2a. Whether the sheet material is placed manually by the worker or by the overhead crane, the sheet material can be placed onto the first roller mechanism 2a from top to bottom.

[0087] (2) The piston rod of the push telescopic rod 73 in the push device 7 extends, and the piston rod of the push telescopic rod 73 drives the push plate 72 to move to the left. The push plate 72 pushes the plate to move to the left and closer to the clamping device 6. When the left side of the plate is inserted between the clamping movable seat 62 and the clamping fixed seat 61 of the clamping device 6, on the one hand, the piston rod of the push telescopic rod 73 retracts, and the piston rod of the push telescopic rod 73 drives the push plate 72 away from the plate; on the other hand, the piston rod of the clamping lifting rod 63 in the clamping device 6 retracts downward, the clamping movable seat 62 moves down, and the clamping movable seat 62 and the clamping fixed seat 61 clamp the left side of the plate.

[0088] (3) The longitudinal moving device 5 drives the clamping device 6 to move longitudinally from front to back. The clamping device 6 clamps the plate and moves from front to back. When the plate to be processed moves to the window 11, the piston rod of the first pressing lifting rod 3a4 in the first pressing mechanism 3a extends downward and pushes the first pressing plate 3a3 down. The first pressing wheel 3a31 on the side of the first pressing plate 3a3 moves down and presses the plate. The piston rod of the second pressing lifting rod 3b4 in the second pressing mechanism 3b extends downward and pushes the second pressing plate 3b3 down. The second pressing wheel 3b31 on the side of the second pressing plate 3b3 moves down and presses the plate, preventing the plate from tilting during subsequent hole processing and keeping the plate stable.

[0089] (4) The upper transverse movement mechanism 4a1 in the upper hole processing device 4a adjusts the transverse position of the upper drilling mechanism 4a3, and the upper vertical movement mechanism 4a2 in the upper hole processing device 4a adjusts the vertical height of the upper drilling mechanism 4a3. The lower the height of the upper drilling mechanism 4a3, the deeper the drilling depth of the upper drilling mechanism 4a3 on the upper surface of the board. Holes include blind holes and through holes. When the hole depth does not penetrate the board, it is called a blind hole. If the upper transverse movement mechanism 4a1 drives the upper drilling mechanism 4a3 to move laterally during the drilling operation, a transverse long hole can be processed on the upper surface of the board. If a longitudinal long hole needs to be processed on the upper surface of the board, the longitudinal movement device 5 needs to drive the board to move longitudinally. The first pressing wheel 3a31 and the second pressing wheel 3b31 pressing on the upper surface of the board can rotate relative to the board. The first pressing wheel 3a31 and the second pressing wheel 3b31 will not hinder the longitudinal movement of the board.

[0090] Simultaneously, the lower transverse movement mechanism 4b1 in the lower hole processing device 4b adjusts the transverse position of the lower drilling mechanism 4b3, and the lower vertical movement mechanism 4b2 in the lower hole processing device 4b adjusts the vertical height of the lower drilling mechanism 4b3. The higher the lower drilling mechanism 4b3 is, the deeper the hole it drills on the lower surface of the board. If, during the drilling operation, the lower transverse movement mechanism 4b1 drives the lower drilling mechanism 4b3 to move laterally, a transverse elongated hole can be processed on the lower surface of the board. If, during the drilling operation, the longitudinal movement device 5 drives the board to move longitudinally, a longitudinal elongated hole can be processed on the lower surface of the board.

[0091] By operating the upper hole processing device 4a and the lower hole processing device 4b simultaneously, holes can be processed on both the upper and lower surfaces of the sheet metal at the same time.

[0092] (5) After the hole processing is completed, the first pressing plate 3a3 in the first pressing mechanism 3a moves upward and away from the plate, the second pressing plate 3b3 in the second pressing mechanism 3b moves upward and away from the plate, the upper drilling mechanism 4a3 in the upper hole processing device 4a moves upward and away from the upper surface of the plate, the lower drilling mechanism 4b3 in the lower hole processing device 4b moves downward and away from the lower surface of the plate, and the longitudinal moving device 5 drives the plate to continue moving backward. After processing is completed, the worker can use an overhead crane to lift and transport the processed plate away.

[0093] Based on the above working principle, it can be seen that this embodiment has the following effects:

[0094] First, compared with the prior art, in this embodiment, when placing the board, there is no upper board telescopic support device to block it, and the board can be placed directly from top to bottom on the first roller mechanism 2a without being blocked by other structures, making it more convenient to place.

[0095] Secondly, by placing the boards from top to bottom, compared with inserting the boards longitudinally in the prior art, the longitudinal length of the production line can be shortened, saving space and improving space utilization.

[0096] Third, since there is no telescopic support device above the board to obstruct the view, it is easier to observe the processing status of the board surface and facilitate quality inspection during the processing.

[0097] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
