[0023] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] In the manufacturing process of mechanical products (such as air valves), drilling equipment is typically used to drill holes in the flanges of the air valves, creating through holes or threaded holes. This allows the flanges to be secured to other components with screws, thus completing the product installation. Please refer to [reference needed]. Figure 1 , Figure 1 This is a structural schematic diagram of the air valve 200. Both ends of the air valve 200 are provided with flanges 201, and each flange 201 is provided with at least one through hole 202. The through holes 202 of each flange 201 are formed by drilling equipment.

[0027] In related technologies, during the process of machining through holes 202 on flange 201 using drilling equipment, the damper 200 is placed on a support platform. One flange 201 is drilled first, then the damper 200 is manually rotated 180° before drilling the other flange 201. Because the damper 200 is large and heavy, rotating it requires significant manpower and time. Furthermore, after rotation, the damper 200 and the drill bit used for machining need to be re-aligned, resulting in low processing efficiency. In addition, the position of the damper 200 may shift during rotation, affecting drilling accuracy and causing asymmetry in the positions of the through holes 202 on the two flanges 201, impacting product quality. Simultaneously, manually rotating the damper 200 poses a safety hazard; operators may be injured due to the excessive weight of the damper 200.

[0028] To at least partially resolve the above issues, please refer to Figures 2 to 8 This application provides a drilling device 100. The drilling device 100 includes a first support 1, a first clamping module 2, a second clamping module 3, a first drilling module 4, and a second drilling module 5.

[0029] For ease of description, the air valve 200 to be drilled will be referred to as workpiece 200.

[0030] Specifically, the first support 1 supports various components of the drilling equipment 100. The first support 1 includes a first upright 11, a second upright 12, and a first bearing platform 13. The first upright 11 is located at one end of the first bearing platform 13, and the second upright 12 is located at the other end of the first bearing platform 13. The first upright 11 and the second upright 12 are arranged opposite to each other along a second direction Y. The first bearing platform 13 is configured to support the workpiece 200, that is, the workpiece 200 can be placed on the upper surface of the first bearing platform 13. The first bearing platform 13 is fixedly connected to the first upright 11 and the second upright 12 to form a stable support structure.

[0031] The first clamping module 2 includes a first driving assembly 21, a first cylinder 22, and a first clamping plate 23. The first driving assembly 21 is disposed on the first upright 11 and drives the first clamping plate 23 to move along a first direction X. The first cylinder 22 is disposed on the first driving assembly 21 and drives the first clamping plate 23 to move along a second direction Y. The first clamping plate 23 is disposed on the first cylinder 22 and can tightly fit against the surface of the workpiece 200. The first direction X is perpendicular to the second direction Y, and the second direction Y is parallel to the arrangement direction of the first upright 11 and the second upright 12.

[0032] The second clamping module 3 includes a second drive assembly 31, a second cylinder 32, and a second clamping plate 33. The second drive assembly 31 is disposed on the second upright 12 and drives the second clamping plate 33 to move along a first direction X. The second cylinder 32 is disposed on the second drive assembly 31 and drives the second clamping plate 33 to move along a second direction Y. The second clamping plate 33 is disposed on the second cylinder 32 and can closely fit the surface of the workpiece 200. Along the second direction Y, the first clamping plate 23 and the second clamping plate 33 are opposite each other, and together they clamp the workpiece 200. Specifically, the first cylinder 22 drives the first clamping plate 23 to approach the second clamping plate 33 along the second direction Y, while the second cylinder 32 drives the second clamping plate 33 to approach the first clamping plate 23 along the second direction Y, so that the first clamping plate 23 and the second clamping plate 33 clamp the workpiece 200 from both sides, thereby fixing the workpiece 200 on the first bearing platform 13 or pushing the workpiece 200 to move along the first direction X.

[0033] The first drilling module 4 is located at one end of the first support platform 13 and is used to drill a hole at one end of the workpiece 200. The second drilling module 5 is opposite to the first drilling module 4 in the second direction Y, and the first drilling module 4 and the second drilling module 5 are located on opposite sides of the first support platform 13. The second drilling module 5 is used to drill a hole at the other end of the workpiece 200. Specifically, the two ends of the workpiece 200 face the first drilling module 4 and the second drilling module 5, respectively. The first drilling module 4 can drill a hole at the end of the workpiece 200 facing it, and the second drilling module 5 can drill a hole at the other end of the workpiece 200 facing it. Since the first drilling module 4 and the second drilling module 5 are located at the two ends of the workpiece 200, drilling can be performed simultaneously or sequentially at both ends of the workpiece 200 without flipping it, which improves processing efficiency.

[0034] In this embodiment, the first clamping plate 23 is driven to move along the second direction Y by the first cylinder 22, and the second clamping plate 33 is driven to move along the second direction Y by the second cylinder 32, so that the first clamping plate 23 and the second clamping plate 33 can jointly clamp the workpiece 200. Then, the first driving assembly 21 drives the first clamping plate 23 to move along the first direction X, and the second driving assembly 31 drives the second clamping plate 33 to move along the first direction X, thereby driving the workpiece 200 to move along the first direction X to a second preset position. Then, the first drilling module 4 drills a hole at one end of the workpiece 200, and the second drilling module 5 drills a hole at the other end of the workpiece 200. Drilling can be done at both ends of the workpiece 200 without flipping it, eliminating the need for manual flipping of the workpiece 200. This improves processing efficiency, reduces the time and complexity required for re-alignment, and also improves drilling accuracy and consistency, reduces the risk of workpiece 200 positional displacement due to flipping, and improves product quality. In addition, eliminating the need for manual flipping of the workpiece 200 helps reduce the labor intensity of operators and improves operational safety.

[0035] In some embodiments, the first support platform 13 is provided with a plurality of first rolling shafts 131 spaced apart along a first direction X. All of the plurality of first rolling shafts 131 are rotatable, and their axes are parallel to a second direction Y. All of the plurality of first rolling shafts 131 are used to support the workpiece 200. When the first clamping plate 23 and the second clamping plate 33 clamp the workpiece 200 and drive the workpiece 200 to move along the first direction X, the plurality of first rolling shafts 131 can rotate with the movement of the workpiece 200, thereby reducing the frictional force during the movement of the workpiece 200 along the first direction X.

[0036] It is worth noting that if the workpiece 200 is clamped solely by the clamping force of the first clamping plate 23 and the second clamping plate 33, the required clamping force will be large when the surface of the workpiece 200 is relatively smooth or the mass of the workpiece 200 is large. Excessive clamping force may cause the workpiece 200 to deform, especially for thin-walled workpieces 200, such as the flange part of the workpiece 200. Excessive clamping force can easily cause the flange to bend and deform, affecting product quality.

[0037] To at least partially address the above-mentioned problems, in some embodiments, at least one of the first clamping plate 23 and the second clamping plate 33 comprises a ferromagnetic material.

[0038] In some embodiments, at least one of the first clamping plate 23 and the second clamping plate 33 comprises a ferrimagnetic material.

[0039] Ferromagnetic or ferrimagnetic materials have magnetic attraction properties, so that the first clamping plate 23 or the second clamping plate 33 can be magnetically fixed to the workpiece 200, which helps to reduce the clamping force of the first clamping plate 23 and the second clamping plate 33 and reduce the risk of deformation of the workpiece 200.

[0040] In some embodiments, the first clamping plate 23 and the second clamping plate 33 can be electromagnet structures, that is, electromagnetic coils are provided inside the first clamping plate 23 and the second clamping plate 33, and the magnetism of the first clamping plate 23 and the second clamping plate 33 is controlled by controlling the on and off of the electromagnetic coils. Specifically, the first clamping plate 23 and the second clamping plate 33 are magnetic when energized and can magnetically attract the workpiece 200, and are not magnetic when de-energized and cannot magnetically attract the workpiece 200. Therefore, when the first clamping plate 23 and the second clamping plate 33 need to clamp the workpiece 200, the first cylinder 22 and the second cylinder 32 can first drive the first clamping plate 23 and the second clamping plate 33 to approach the workpiece 200, and then energize the first clamping plate 23 and the second clamping plate 33 to magnetically attract the workpiece 200, thereby achieving the clamping of the workpiece 200. When the first clamping plate 23 and the second clamping plate 33 need to release the workpiece 200, the power to the first clamping plate 23 and the second clamping plate 33 can be cut off first, causing the first clamping plate 23 and the second clamping plate 33 to lose their magnetism. Then, the first cylinder 22 and the second cylinder 32 drive the first clamping plate 23 and the second clamping plate 33 away from the workpiece 200, thereby releasing the workpiece 200. Through the electromagnet structure, the power to the first clamping plate 23 and the second clamping plate 33 can be cut off before releasing the workpiece 200, which facilitates the release of the workpiece 200, improves the reliability of the release of the workpiece 200, and reduces the risk of the workpiece 200 sticking to the clamping plate due to residual magnetic force.

[0041] In some embodiments, the drilling device 100 further includes a second sensor 30. The second sensor 30 is located at one end of the first support platform 13 near the first drilling module 4, and is used to detect the position of the workpiece 200. Specifically, when the workpiece 200 moves along the first direction X, the second sensor 30 can detect whether the workpiece 200 has reached a preset drilling position, i.e., a second preset position. When the second sensor 30 detects that the workpiece 200 has moved to the second preset position, the second sensor 30 sends a signal to the controller 10, and the controller 10 controls the first clamping module 2 and the second clamping module 3 to stop moving, and controls the first drilling module 4 and the second drilling module 5 to drill the workpiece 200.

[0042] In some embodiments, the workpiece 200 typically requires multiple through holes 202, which are spaced apart in the first direction X. For ease of explanation, in the first direction X, the multiple through holes 202 are sequentially divided into a first column, a second column, a third column, and so on, according to the distance between the through holes 202 and one end of the workpiece 200. The through holes 202 in the first column are closest to the front end 203 of the workpiece 200, followed by the second column, and so on. When the workpiece 200 is in a second preset position, the first drilling module 4 and the second drilling module 5 can drill the first column of through holes 202 into the workpiece 200.

[0043] Specifically, after machining the first row of through holes 202, the first clamping plate 23 and the second clamping plate 33 can release the workpiece 200. Then, the first driving assembly 21 and the second driving assembly 31 drive the first clamping plate 23 and the second clamping plate 33 to retract a preset distance along the first direction X, respectively. The preset distance is equal to the distance between the first row of through holes 202 and the second row of through holes 202 in the first direction X. Next, the first cylinder 22 and the second cylinder 32 drive the first clamping plate 23 and the second clamping plate 33 to move closer to each other along the second direction Y, thereby clamping the workpiece 200 again. Then, the first driving assembly 21 and the second driving assembly 31 drive the first clamping plate 23 and the second clamping plate 33 to advance a preset distance along the first direction X, thereby driving the workpiece 200 to advance a preset distance along the first direction X. At this time, the first drilling module 4 and the second drilling module 5 of the workpiece 200 can machine the second row of through holes 202 into the workpiece 200. The machining steps for the third row and subsequent through holes 202 are similar to those for the second row.

[0044] In some embodiments, the first drive assembly 21 includes a first connecting frame 211, a first motor 212, a first lead screw 213, and a first drive block 214. The first connecting frame 211 is disposed on the first upright 11 and is fixedly connected to the first upright 11. The first motor 212 is disposed at one end of the first connecting frame 211, one end of the first lead screw 213 is connected to the output shaft of the first motor 212, and the other end of the first lead screw 213 is rotatably connected to the first connecting frame 211. The first drive block 214 is provided with a first screw hole 2141, the first lead screw 213 is threaded into the first screw hole 2141, and the first cylinder 22 is fixedly disposed on the first drive block 214.

[0045] During operation, the first motor 212 drives the first lead screw 213 to rotate, and the rotation of the lead screw 213 drives the first drive block 214 to move along the first direction X. The first drive block 214 drives the first cylinder 22 and the first clamping plate 23 to move along the first direction X, thereby achieving precise positioning and movement of the first clamping plate 23 along the first direction X. By driving the lead screw to rotate through the motor, the lead screw engages with the threaded hole, thereby driving the drive block to move along the first direction X. This structure has high transmission accuracy and smooth movement, which is beneficial to improving clamping stability and drilling accuracy. At the same time, the lead screw transmission has self-locking properties, which can maintain the position when the drive stops, which is beneficial to improving the reliability of workpiece 200 positioning.

[0046] In some embodiments, the first driving component 21 further includes a guide rail (not shown) and a slider (not shown). The guide rail is disposed on the first connecting frame 211, the slider is slidably disposed on the guide rail, and the first driving block 214 is fixed to the slider, thereby limiting the sliding direction of the first driving block 214.

[0047] In some embodiments, the second drive assembly 31 includes a second connecting frame 311, a second motor 312, a second lead screw 313, and a second drive block 314. The second connecting frame 311 is disposed on the second upright 12 and is fixedly connected to the second upright 12. The second motor 312 is disposed at one end of the second connecting frame 311. One end of the second lead screw 313 is connected to the output shaft of the second motor 312, and the other end of the second lead screw 313 is rotatably connected to the second connecting frame 311. The second drive block 314 is provided with a second threaded hole 3141, and the second lead screw 313 is threadedly engaged with the second threaded hole 3141. The second cylinder 32 is fixedly disposed on the second drive block 314.

[0048] The working principle of the second drive assembly 31 is similar to that of the first drive assembly 21. Specifically, the second motor 312 drives the second lead screw 313 to rotate, and the rotation of the second lead screw 313 drives the second drive block 314 to move along the first direction X. The second drive block 314 then drives the second cylinder 32 and the second clamping plate 33 to move along the first direction X. The structure and effect of the second drive assembly 31 are similar to those of the first drive assembly 21, which helps to improve the accuracy and stability of the second clamping plate 33 moving along the first direction X.

[0049] In some embodiments, the second drive assembly 31 further includes a guide rail (not shown) and a slider (not shown). The guide rail is disposed on the second connecting frame 311, the slider is slidably disposed on the guide rail, and the second drive block 314 is fixed to the slider, thereby limiting the sliding direction of the second drive block 314.

[0050] It is worth noting that during the drilling process, the workpiece 200 needs to be clamped by the first clamping plate 23 and the second clamping plate 33. In the first direction X, the first clamping plate 23 and the second clamping plate 33 need to have sufficient contact length with the workpiece 200 to prevent the workpiece 200 from moving or shaking during the drilling process. This results in the portion of the workpiece 200 clamped by the first clamping plate 23 and the second clamping plate 33 being unable to be drilled. For example, if the total length of the workpiece 200 is 1000mm, the first clamping plate 23 and the second clamping plate 33 need to have a contact length of 200mm with the workpiece 200 to stably clamp it. In this case, a 200mm area at the rear end 204 of the workpiece 200 cannot be drilled by the first drilling module 4 and the second drilling module 5 because this area is blocked by the first clamping plate 23 and the second clamping plate 24. This will prevent the flange at the rear end 204 of the workpiece 200 from being drilled. In this case, the front end 203 and the rear end 204 of the workpiece 200 are opposite each other, with the front end 203 in front and the rear end 204 behind along the direction of the workpiece 200's movement.

[0051] To at least partially address the aforementioned problems, in some embodiments, the drilling equipment 100 further includes a second support 6, a third clamping module 7, and a fourth clamping module 8. The structure of the second support 6 is similar to that of the first support 1, and the second support 6 includes a second bearing platform 61, a third upright 62, and a fourth upright 63. The second bearing platform 61 is generally flat, with a smooth upper surface, and is configured to support the workpiece 200. The second bearing platform 61 and the first bearing platform 13 are spaced apart along a first direction X, meaning the second bearing platform 61 is located downstream of the first bearing platform 13 along the first direction X. The third upright 62 and the fourth upright 63 are opposite each other along a second direction Y, and are located on opposite sides of the second bearing platform 61. In the first direction X, the first drilling module 4 and the second drilling module 5 are both located between the first support platform 13 and the second support platform 61. That is, the first drilling module 4 and the second drilling module 5 are located in the area between the first support platform 13 and the second support platform 61, and can simultaneously drill holes in the workpiece 200 located on the first support platform 13 and the second support platform 61.

[0052] The third clamping module 7 includes a third drive assembly 71, a third cylinder 72, and a third clamping plate 73. The third drive assembly 71 is mounted on the third upright 62 and drives the third clamping plate 73 to move along a first direction X. The third cylinder 72 is mounted on the third drive assembly 71 and drives the third clamping plate 73 to move along a second direction Y. The third clamping plate 73 is mounted on the third cylinder 72 and can tightly fit against the surface of the workpiece 200.

[0053] The fourth clamping module 8 includes a fourth drive assembly 81, a fourth cylinder 82, and a fourth clamping plate 83. The fourth drive assembly 81 is disposed on the fourth stand 63 and drives the fourth clamping plate 83 to move along a first direction X. The fourth cylinder 82 is disposed on the fourth drive assembly 81 and drives the fourth clamping plate 83 to move along a second direction Y. The fourth clamping plate 83 is disposed on the fourth cylinder 82 and can closely fit the surface of the workpiece 200. Along the second direction Y, the third clamping plate 73 and the fourth clamping plate 83 are opposite each other, and the third clamping plate 73 and the fourth clamping plate 83 together clamp the workpiece 200.

[0054] By configuring the second support 6, the third clamping module 7, and the fourth clamping module 8, when the workpiece 200 is clamped by the first clamping plate 23 and the second clamping plate 33 and moves along the first direction X to the vicinity of the second support platform 61, a portion of the workpiece 200 has already extended onto the second support platform 61, and this portion has already been drilled. At this time, the portion of the workpiece 200 located on the second support platform 61 can be clamped together by the third clamping module 7 and the fourth clamping module 8. Then, the first clamping plate 23 and the second clamping plate 33 release the workpiece 200, thereby exposing the portion of the workpiece 200 that was originally clamped by the first clamping plate 23 and the second clamping plate 33. Then, the workpiece 200 is driven to continue moving along the first direction X by the third clamping module 7 and the fourth clamping module 8, so that the first drilling module 4 and the second drilling module 5 can drill the portion of the workpiece 200 that was originally clamped by the first clamping plate 23 and the second clamping plate 33.

[0055] In some embodiments, at least one of the third clamping plate 73 and the fourth clamping plate 83 comprises a ferromagnetic material.

[0056] In some embodiments, at least one of the third clamping plate 73 and the fourth clamping plate 83 comprises a ferrimagnetic material.

[0057] In some embodiments, the third clamping plate 73 and the fourth clamping plate 83 may also adopt an electromagnet structure. The magnetism of the third clamping plate 73 and the fourth clamping plate 83 is controlled by controlling the on and off of the electromagnetic coil. The power can be cut off before the workpiece 200 is released, so that the third clamping plate 73 and the fourth clamping plate 83 can release the workpiece 200.

[0058] In some embodiments, the third drive assembly 71 and the first drive assembly 21 have similar structures, and the fourth drive assembly 81 and the second drive assembly 31 have similar structures. Specifically, the third drive assembly 71 also includes a connecting frame, a motor, a lead screw, and a drive block, and the fourth drive assembly 81 also includes a connecting frame, a motor, a lead screw, and a drive block. The working principle and effect of the third drive assembly 71 and the fourth drive assembly 81 are similar to those of the first drive assembly 21 and the second drive assembly 31, and will not be described in detail in this application.

[0059] In some embodiments, the second support platform 61 is provided with a plurality of second rolling shafts 611 spaced apart along the first direction X. The structure and function of the plurality of second rolling shafts 611 are similar to those of the plurality of first rolling shafts 131. The plurality of second rolling shafts 611 are all rotatable and are all used to support the workpiece 200, thereby reducing the frictional force of the workpiece 200 during its movement along the first direction X, which is beneficial to improving the smoothness of the movement of the workpiece 200 driven by the third drive assembly 71 and the fourth drive assembly 81.

[0060] In some embodiments, the first drilling module 4 includes a fifth support 41, a fifth drive assembly 42, and a first drilling assembly 43. The fifth support 41 is generally plate-shaped or columnar in structure and is fixedly mounted on the base or other support structure of the drilling equipment 100. The fifth drive assembly 42 is disposed on the fifth support 41 and is used to drive the first drilling assembly 43 to move along the third direction Z. The first drilling assembly 43 is disposed on the fifth drive assembly 42 and includes a drill bit and a power head for driving the drill bit to rotate. The power head can be an electric spindle or a pneumatic motor.

[0061] The fifth drive assembly 42 can drive the first drilling assembly 43 to move along the third direction Z, that is, the first drilling assembly 43 can move up and down, so that through holes 202 can be machined at different heights of the workpiece 200, which is beneficial to adapt to workpieces 200 of different specifications, such as air valve flanges of different heights, and improve the applicability and processing flexibility of the equipment.

[0062] In some embodiments, the second drilling module 5 includes a sixth support frame 51, a sixth drive assembly 52, and a second drilling assembly 53. The sixth support frame 51 is fixedly mounted on the base or other support structure of the drilling equipment 100. The sixth drive assembly 52 is mounted on the sixth support frame 51 and is used to drive the second drilling assembly 53 to move along a third direction Z. The second drilling assembly 53 is mounted on the sixth drive assembly 52 and includes a drill bit and a power head for driving the drill bit to rotate. The sixth drive assembly 52 can drive the second drilling assembly 53 to move along a third direction Z, and the second drilling assembly 53 can move up and down, thereby machining through holes 202 at different heights of the workpiece 200, which is beneficial for adapting to workpieces 200 of different specifications and improving the applicability and processing flexibility of the equipment.

[0063] In some embodiments, the drilling equipment 100 further includes a loading module 9. The loading module 9 is used to transport the workpiece 200 to the first support platform 13. The loading module 9 includes a lifting assembly 91, a lifting platform 92, and a pushing assembly 93. The lifting platform 92 is configured to carry the workpiece 200. The lifting platform 92 is disposed on the lifting assembly 91, which drives the lifting platform 92 to move along a third direction Z, i.e., the lifting assembly 91 can drive the lifting platform 92 to move up and down. When the lifting platform 92 moves to a preset height, the lifting platform 92 docks with the first support platform 13, i.e., the upper surface of the lifting platform 92 is at the same height as the upper surface of the first support platform 13, and the workpiece 200 can smoothly move from the lifting platform 92 to the first support platform 13.

[0064] The pushing component 93 is disposed on the lifting platform 92. The pushing component 93 is used to push the workpiece 200 along the first direction X towards the first bearing platform 13. Specifically, after the workpiece 200 is placed on the lifting platform 92 by a transfer device (e.g., forklift, AGV, or conveyor belt), the lifting component 91 drives the lifting platform 92 to rise to the position where it docks with the first bearing platform 13. Then, the pushing component 93 pushes the workpiece 200 along the first direction X, pushing the workpiece 200 from the lifting platform 92 onto the first bearing platform 13 until the workpiece 200 reaches the first preset position, so that the first clamping plate 23 and the second clamping plate 33 can clamp the workpiece 200.

[0065] By setting up the feeding module 9, the workpiece 200 can be transported to the lifting platform 92 by the transfer device. The lifting platform 92 is driven to rise to the position where it docks with the first bearing platform 13 by the lifting component 91. The workpiece 200 is pushed to the first preset position by the pushing component 93, so that the first clamping plate 23 and the second clamping plate 33 can clamp the workpiece 200. There is no need for manual lifting of the workpiece 200 and placing it on the first bearing platform 13, which helps to save manpower, improve processing efficiency, reduce the labor intensity of operators, and at the same time, it helps to realize the automation of the production line and improve the overall production efficiency.

[0066] In some embodiments, the pushing assembly 93 includes a first pushing frame 931, a first pushing motor 932, a first pushing screw 933, and a first pushing block 934. The first pushing frame 931 is disposed at one end of the lifting platform 92. The first pushing motor 932 is disposed on the first pushing frame 931. One end of the first pushing screw 933 is connected to the output shaft of the first pushing motor 932, and the other end of the first pushing screw 933 is rotatably connected to the first pushing frame 931. The first pushing block 934 is provided with a third screw hole 9341, and the first pushing screw 933 is threadedly engaged with the third screw hole 9341.

[0067] The pushing assembly 93 also includes a second pushing frame 935, a second pushing motor 936, a second pushing screw 937, a second pushing block 938, and a pushing plate 939. The second pushing frame 935 is located at the end of the lifting platform 92 away from the first pushing frame 931, and the second pushing motor 936 is located on the second pushing frame 935. One end of the second pushing screw 937 is connected to the output shaft of the second pushing motor 936, and the other end of the second pushing screw 937 is rotatably connected to the second pushing frame 935. The second pushing block 938 is provided with a fourth screw hole 9381, and the second pushing screw 937 is threaded into the fourth screw hole 9381.

[0068] The push plate 939 is plate-shaped, with one end connected to the first push block 934 and the other end connected to the second push block 938. The push plate 939 is configured to push the workpiece 200 along the first direction X towards the first support platform 13. Specifically, the push plate 939 is located on the side of the workpiece 200 away from the first support platform 13. During operation, the first push motor 932 drives the first push screw 933 to rotate, and the rotation of the first push screw 933 drives the first push block 934 to move along the first direction X. Simultaneously, the second push motor 936 drives the second push screw 937 to rotate, and the rotation of the second push screw 937 drives the second push block 938 to move along the first direction X. Since both ends of the push plate 939 are connected to the first push block 934 and the second push block 938 respectively, the synchronous movement of the first push block 934 and the second push block 938 will drive the push plate 939 to move along the first direction X. The first pusher block 934 and the second pusher block 938 push the pusher plate 939 from both ends of the pusher plate 939 to move along the first direction X. The pusher plate 939 is used to push the workpiece 200 to move along the first direction X. The double-sided pushing method is conducive to improving the balance of the pushing force and reducing the risk of the workpiece 200 deviating or tilting during the pushing process.

[0069] In some embodiments, the pushing assembly 93 further includes a pushing cylinder 930. The pushing cylinder 930 is disposed at one end of the push plate 939 near the first supporting platform 13, with the piston rod of the pushing cylinder 930 facing the first supporting platform 13. By providing the pushing cylinder 930, the lengths of the first pushing frame 931, the first pushing screw 933, the second pushing frame 935, and the second pushing screw 937 in the first direction X can be shortened, thus saving costs.

[0070] In some embodiments, the drilling equipment 100 further includes a first sensor 20. The first sensor 20 is disposed at one end of the first support platform 13 near the feeding module 9, that is, the first sensor 20 is located at one end of the first support platform 13 near the lifting platform 92. The first sensor 20 is used to detect the position of the workpiece 200. Specifically, the first sensor 20 can be a photoelectric sensor, a proximity switch, or other type of position sensor. When the workpiece 200 is pushed by the pushing assembly 93 to move along the first direction X, the first sensor 20 can detect whether the workpiece 200 has reached a first preset position. The first preset position is the position where the workpiece 200 is clamped by the first clamping plate 23 and the second clamping plate 33. At this position, the workpiece 200 is between the first clamping plate 23 and the second clamping plate 33, which facilitates the clamping of the workpiece 200 by the first clamping plate 23 and the second clamping plate 33.

[0071] When the first sensor 20 detects that the workpiece 200 has moved to the first preset position, the first sensor 20 sends a signal to the controller 10. The controller 10 controls the pusher assembly 93 to stop moving and controls the first cylinder 22 and the second cylinder 32 to drive the first clamping plate 23 and the second clamping plate 33 to move closer to each other along the second direction Y, thereby clamping the workpiece 200. Then, the first drive assembly 21 and the second drive assembly 31 drive the first clamping plate 23 and the second clamping plate 33 to move along the first direction X, moving the workpiece 200 from the first preset position to the second preset position, i.e., the drilling position. The first sensor 20 facilitates accurate detection and automatic control of the workpiece 200's position, improves the automation level of loading and clamping, and reduces the need for manual intervention.

[0072] In some embodiments, the drilling equipment 100 further includes a material unloading module 40, which is located at the end of the second support platform 61 away from the first support platform 13. The material unloading module 40 is used to remove the workpiece 200 after drilling.

[0073] In this embodiment, the first clamping plate 23 is driven to move along the second direction Y by the first cylinder 22, and the second clamping plate 33 is driven to move along the second direction Y by the second cylinder 32, so that the first clamping plate 23 and the second clamping plate 33 can jointly clamp the workpiece 200. Then, the first driving assembly 21 drives the first clamping plate 23 to move along the first direction X, and the second driving assembly 31 drives the second clamping plate 33 to move along the first direction X, thereby driving the workpiece 200 to move to a preset position along the first direction X. Then, the first drilling module 4 drills a hole at one end of the workpiece 200, and the second drilling module 5 drills a hole at the other end of the workpiece 200. Drilling can be done at both ends of the workpiece 200 without flipping it. Compared with related technologies, this embodiment does not require manual flipping of the workpiece 200, which is beneficial to improving processing efficiency, reducing the time and complexity required for re-alignment, improving drilling accuracy and consistency, reducing the risk of workpiece 200 positional displacement due to flipping, and improving product quality. Furthermore, eliminating the need for manual rotation of workpiece 200 reduces the labor intensity of operators, improves operational safety, and lowers the risk of injury due to the weight of workpiece 200. By positioning the first drilling module 4 and the second drilling module 5 at opposite ends of workpiece 200, drilling can be performed simultaneously or sequentially at both ends, shortening the processing cycle and increasing production efficiency. The addition of the feeding module 9 facilitates automatic feeding of workpiece 200, reducing labor costs and enhancing the automation level of the production line.

[0074] This application also provides a drilling method applied to the aforementioned drilling equipment 100. Please refer to [link / reference]. Figure 2 , Figure 4 and Figure 9The drilling equipment 100 includes a controller 10, a first sensor 20, a second sensor 30, and a feeding module 9. The feeding module 9 includes a lifting assembly 91, a lifting platform 92, and a pushing assembly 93. The lifting assembly 91 is located at one end of the first support platform 13, and the lifting platform 92 is disposed on the lifting assembly 91. The lifting assembly 91 drives the lifting platform 92 to move along the third direction Z. The pushing assembly 93 is disposed on the lifting assembly 91. The first sensor 20 is disposed at the end of the first support platform 13 near the lifting assembly 91, and the second sensor 30 is disposed at the end of the first support platform 13 away from the lifting assembly 91. The first sensor 20, the second sensor 30, the pushing assembly 93, the first clamping module 2, the second clamping module 3, the first drilling module 4, and the second drilling module 5 are all communicatively connected to the controller 10.

[0075] Please see Figure 10 The drilling method includes the following steps: Step 01: Provide the transfer device.

[0076] Step 02: Transfer the workpiece to the lifting platform using the transfer device.

[0077] Step 03: Drive the lifting platform to rise to the preset height along a third direction using the lifting component.

[0078] The preset height refers to the position where the upper surface of the lifting platform is at the same height as the upper surface of the first bearing platform.

[0079] Step 04: The workpiece is pushed along the first direction by the pusher assembly and moves closer to the first bearing platform.

[0080] Step 05: When the workpiece moves to the first preset position, the first sensor sends a first signal to the controller.

[0081] The first preset position is the position where the workpiece is clamped by the first and second clamping plates. After the first sensor detects that the workpiece has reached the first preset position, it sends a first signal to the controller, notifying the controller that the workpiece has arrived in place. Automatic detection of the workpiece position using the first sensor improves positioning accuracy and reduces the need for manual observation and judgment.

[0082] Step 06: According to the first signal, the controller controls the pusher assembly to stop moving, and the controller controls the first cylinder to drive the first clamping plate to move closer to the second clamping plate in the second direction, and controls the second cylinder to drive the second clamping plate to move closer to the first clamping plate in the second direction, so that the first clamping plate and the second clamping plate jointly clamp the workpiece.

[0083] Step 07: Drive the first clamping plate to move along the first direction through the first driving component, and drive the second clamping plate to move along the first direction through the second driving component, so as to drive the workpiece to move along the first direction.

[0084] Specifically, the first driving component and the second driving component synchronously drive the first clamping plate and the second clamping plate to move along a first direction. The first clamping plate and the second clamping plate move the workpiece together, moving the workpiece from a first preset position to a drilling position. Precise control of the first driving component and the second driving component helps improve the workpiece positioning accuracy, ensuring the workpiece is accurately moved to the drilling position.

[0085] Step 08: When the workpiece moves to the second preset position, the second sensor sends a second signal to the controller.

[0086] The second preset position is the drilling position, where the part of the workpiece to be drilled is aligned with the drill bits of the first and second drilling modules. After the second sensor detects that the workpiece has reached the second preset position, it sends a second signal to the controller, notifying the controller that the workpiece has reached the drilling position.

[0087] Step 09: According to the second signal, the controller controls the first clamping module and the second clamping module to stop moving, the controller controls the first drilling module to drill holes in the workpiece, and the controller controls the second drilling module to drill holes in the workpiece.

[0088] Step 10: The first clamping module and the second clamping module work together to push the workpiece to move a preset distance along the first direction.

[0089] Specifically, after the first and second drilling modules complete the machining of a certain column (e.g., the first column) of through holes, the controller controls the first and second drive components to drive the first and second clamping plates to move a preset distance along a first direction, and the workpiece moves accordingly. The preset distance is equal to the distance between two adjacent columns of through holes in the first direction. After the workpiece has moved the preset distance, the drill bits of the first and second drilling modules are aligned with the positions of the next column to be drilled.

[0090] Step 11: The first drilling module and the second drilling module drill holes in the workpiece, and then return to step 10, where the first clamping module and the second clamping module jointly push the workpiece to move a preset distance in the first direction until, in the first direction, the first clamping plate protrudes from the end of the workpiece away from the first drilling module (i.e., the rear end of the workpiece).

[0091] Specifically, the controller controls the first drilling module and the second drilling module to drill holes in the workpiece, completing the machining of the current column of through holes. Then, it returns to step 10, where the first clamping module and the second clamping module push the workpiece again along the first direction by a preset distance, and then drill again. Steps 10 and 11 are repeated until, in the first direction, the first clamping plate protrudes beyond the rear end of the workpiece, meaning the workpiece has moved to the vicinity of the second support, and most of the workpiece has extended onto the second support platform.

[0092] Step 12: The first and second clamping modules release the workpiece, while the third and fourth clamping modules clamp the workpiece.

[0093] Specifically, when most of the workpiece has extended onto the second support platform, the controller controls the third and fourth cylinders to drive the third and fourth clamping plates closer to each other, clamping the portion of the workpiece located on the second support platform. The third and fourth clamping modules take over the clamping of the workpiece, exposing the portion previously held by the first and second clamping plates.

[0094] Step 13: Push the workpiece along the first direction a preset distance using the third clamping module and the fourth clamping module.

[0095] Step 14: The first and second drilling modules drill holes in the workpiece, and then return to step 13 until the workpiece is misaligned with the drill bit of the first drilling module in the first direction. Steps 13 and 14 are repeated until the workpiece has completely passed through the drilling positions of the first and second drilling modules in the first direction. At this point, all drilling positions on the workpiece have been completed, including the portions originally held by the first and second clamping plates. By cyclically executing the pushing and drilling steps, it is beneficial to complete the machining of all through holes along the entire length of the workpiece, improving the completeness and coverage of the drilling.

[0096] Step 15: The controller controls the third and fourth clamping plates to release the workpiece. The workpiece that has been drilled can be removed from the drilling equipment through the unloading module or manually and enter the next process or finished product area.

[0097] This method achieves automated workpiece loading, positioning, clamping, and drilling, which improves the level of automation, reduces labor costs, and increases production efficiency. Furthermore, the relay clamping by the first, second, third, and fourth clamping modules allows drilling to be completed along the entire length of the workpiece, improving the coverage and integrity of the drilling. Drilling both ends of the workpiece simultaneously or sequentially by the first and second drilling modules eliminates the need to flip the workpiece, further improving processing efficiency and reducing the complexity of realignment.

[0098] In some embodiments, step 10: the step of pushing the workpiece along the first direction to move a preset distance by the first clamping module and the second clamping module together further includes: Step 101: Drive the first clamping plate to move away from the second clamping plate in the second direction using the first cylinder, and drive the second clamping plate to move away from the first clamping plate in the second direction using the second cylinder, so that both the first clamping plate and the second clamping plate are separated from the workpiece.

[0099] Step 102: Drive the first clamping plate back a preset distance along the first direction using the first driving component, and drive the second clamping plate back a preset distance along the first direction using the second driving component. Specifically, the first driving component and the second driving component synchronously drive the first clamping plate and the second clamping plate back a preset distance along the first direction. The preset distance is equal to the spacing between two adjacent rows of through holes in the first direction.
