Description

Technical Field

[0001] This utility model relates to the field of automatic drilling technology for hollow boards, and specifically to a high-precision automatic drilling device for hollow boards. Background Technology

[0002] With the widespread application of hollow boards in packaging, construction, logistics and other fields, the demand for drilling processing of hollow boards is increasing to meet the assembly, connection and other usage requirements in different scenarios. As a result, automatic drilling equipment for hollow boards has also developed and been applied rapidly.

[0003] However, in existing technologies, the insufficient clamping stability of hollow boards during drilling is a prominent issue. Specifically, the clamping structure is difficult to adapt flexibly to the thickness and size of the hollow board, resulting in uneven clamping force. Some areas are too loose, which can easily cause longitudinal or lateral displacement of the hollow board under the impact of drilling. At the same time, the lack of effective support for the bottom of the hollow board during clamping causes slight warping of the board due to uneven force during drilling, which in turn causes the drilling position to deviate from the preset trajectory, and burrs and cracks to appear on the hole wall. This not only reduces the accuracy of drilling but also affects the structural integrity of the hollow board, making it difficult to meet the strict requirements of high-precision processing for dimensional tolerances and appearance quality. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a high-precision automatic drilling device for hollow boards, which has the advantages of stable and flexible clamping of hollow boards, effectively preventing displacement during drilling, and ensuring drilling accuracy and processing quality. This solves the problem of low drilling accuracy and poor processing quality caused by insufficient clamping stability of hollow boards in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-precision automatic drilling device for hollow boards, comprising a frame, L-shaped support rods fixedly installed on both sides of the frame, a drilling mechanism disposed between the two L-shaped support rods, the drilling mechanism being disposed at the top of the frame, a hydraulic cylinder fixedly installed at the middle position of one of the L-shaped support rods near the frame, a motor fixedly installed on the side of the L-shaped support rod near the bottom and away from the frame, a rectangular frame fixedly installed at the top of the frame, two guide grooves symmetrically opened at the top of the rectangular frame, a clamping assembly for clamping the hollow board being disposed inside the rectangular frame, the guide grooves cooperating with the clamping assembly, a collection and cleaning assembly for cleaning drilling waste being disposed inside the frame and below the clamping assembly, the motor cooperating with the collection and cleaning assembly, the clamping assembly being composed of an H-shaped mounting plate and a clamping plate.

[0006] As a preferred embodiment of this utility model, the clamping assembly includes an H-shaped mounting plate, which is fixedly installed in the middle position of the frame near the top. A connecting rod is rotatably installed at the top center of the H-shaped mounting plate, and connecting rods are rotatably installed at both ends of the top of the connecting rod.

[0007] As a preferred embodiment of the present invention, the clamping assembly further includes two clamping plates, which are symmetrically arranged on the top of the connecting rod. The output end of the hydraulic cylinder is fixedly installed on one side of one of the clamping plates, and the middle position of the bottom of the clamping plate is rotatably installed on the other end of the connecting rod. Both ends of the clamping plate are fixedly installed with L-shaped guide rods, and the other end of the L-shaped guide rods is movably sleeved inside the guide groove.

[0008] As a preferred embodiment of the present invention, the clamping assembly further includes two rectangular mounting slots, which are symmetrically opened at the bottom of the clamping plate, and an L-shaped support plate is rotatably mounted inside the rectangular mounting slots.

[0009] As a preferred technical solution of this utility model, the clamping assembly further includes a plurality of first springs, the first springs being fixedly installed on the inner top surface of the rectangular mounting groove, and the other end of the first springs being fixedly installed on the side of the L-shaped support plate near the bottom end, the L-shaped support plate being in an inclined state in the initial state.

[0010] As a preferred embodiment of this utility model, the collection and cleaning assembly includes a rotating rod, which is rotatably mounted between two L-shaped support rods. The end of the rotating rod near the motor is fixedly mounted to the output end of the motor, and a cam is fixedly mounted at the middle position of the outer side of the rotating rod.

[0011] As a preferred technical solution of this utility model, the collection and cleaning component further includes a collection box, which is fixedly installed inside the frame and located at the bottom of the H-shaped mounting plate. One side of the collection box is open, and the bottom surface of the collection box has an movable hole. Two second springs are symmetrically fixedly installed on the bottom surface of the collection box away from the open.

[0012] As a preferred technical solution of this utility model, the collection and cleaning assembly further includes a rectangular plate. One end of the rectangular plate is rotatably installed at the bottom of the collection box opening. The top of the second spring is fixedly installed at the bottom of the other end of the rectangular plate. A top block is fixedly installed at the bottom of the rectangular plate. The top block passes through a movable hole and is used in conjunction with a cam. The external dimensions of the rectangular plate are adapted to the internal space dimensions of the collection box. The rectangular plate is set in an inclined state towards the collection box opening.

[0013] The beneficial effects of this utility model are as follows: This invention achieves stable and flexible clamping of hollow boards through a clamping assembly. When clamping the hollow board, the hollow board first contacts the L-shaped support plate in its initial tilted state. As the clamping action progresses, the L-shaped support plate is squeezed by the side of the hollow board and rotates to a vertical position within the rectangular mounting groove. At this point, the L-shaped support plate firmly supports the bottom of the hollow board. Together with the clamping plate and connecting rod, the hollow board is firmly fixed, effectively preventing displacement during the drilling process. This greatly improves the stability during drilling and ensures the accuracy of the drilling position and the processing quality.

[0014] Meanwhile, the motor drives the rotating rod to rotate the cam, which periodically pushes the top block, causing the rectangular plate to swing up and down around the rotating connection point between itself and the bottom of the collection box opening. This reciprocating motion can automatically and efficiently clean the drilling waste accumulated in the collection box without manual cleaning, significantly saving labor costs, improving overall work efficiency, and reducing interference to the drilling work caused by waste accumulation.

[0018] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 8 The present invention will be further described below.

[0019] A high-precision automatic drilling device for hollow boards includes a frame 1. L-shaped support rods 2 are fixedly installed on both sides of the frame 1. A drilling mechanism 3 is arranged between the two L-shaped support rods 2. The drilling mechanism 3 is located at the top of the frame 1. A hydraulic cylinder 4 is fixedly installed at the middle position of the L-shaped support rod 2 near the frame 1. A motor 7 is fixedly installed on the side of the L-shaped support rod 2 near the bottom and away from the frame 1. A rectangular frame 5 is fixedly installed at the top of the frame 1. Two guide grooves 6 are symmetrically opened at the top of the rectangular frame 5. A clamping component for clamping hollow boards is arranged inside the rectangular frame 5. The guide grooves 6 are used in conjunction with the clamping component. A collection and cleaning component for cleaning drilling waste is arranged inside the frame 1 and below the clamping component. The motor 7 is used in conjunction with the collection and cleaning component. The clamping component consists of an H-shaped mounting plate 15 and a clamping plate 18.

[0020] In this embodiment, frame 1 serves as the basic support component of the entire device, providing a stable mounting base for components such as L-shaped support rods 2 and rectangular frames 5. The L-shaped support rods 2 are fixed to both sides of frame 1, providing mounting support for the drilling mechanism 3 and ensuring its stable placement on top of frame 1. Additionally, a hydraulic cylinder 4 is fixedly installed at the middle of the L-shaped support rod 2 near frame 1, and a motor 7 is fixedly installed near the bottom and away from frame 1. The motor 7 is externally powered. The drilling mechanism 3, comprising a control box, two hydraulic rods, an adjusting plate, and several drilling metal rods, is the core component for drilling the hollow board. The control box is fixed between the two L-shaped support rods 2. The two symmetrically fixed hydraulic rods at its bottom can move the adjusting plate up and down. Several adjusting holes on the adjusting plate are used to fix the drilling metal rods. The control box controls the extension and retraction of the hydraulic rods, causing the drilling metal rods to move up and down, thereby performing the drilling operation on the hollow board fixed to the clamping assembly. The hydraulic cylinder 4 is fixed to the side of the L-shaped support rod 2 near frame 1. In the middle, its output end is fixedly connected to one side of one of the clamping plates 18, providing power for the movement of the clamping assembly. When the hydraulic cylinder 4 extends or retracts, it directly pushes the clamping plate 18 connected to it to move. Through the cooperation of the clamping plate 18 with the connecting rod 17 and the connecting rod 16, it drives the other clamping plate 18 to move synchronously, realizing the opening and closing of the two clamping plates 18, and completing the clamping or releasing action of the hollow plate. The rectangular frame 5 is fixed to the top of the frame 1, and the two guide grooves 6 at its top cooperate with the L-shaped guide rods 19 at both ends of the clamping plate 18 to restrict the L-shaped guide rods 19. The direction of movement of 9 ensures that the clamping plate 18 moves smoothly along the guide groove 6 inside the rectangular frame 5, ensuring the movement accuracy of the clamping assembly. The motor 7 is fixed on the side of the L-shaped support rod 2 near the bottom and away from the frame 1. Its output end is fixedly connected to the end of the rotating rod 8 near the motor 7 to provide power for the collection and cleaning assembly. The clamping assembly consists of the H-shaped mounting plate 15 and the clamping plate 18 to achieve stable clamping of the hollow plate. The collection and cleaning assembly is used to automatically clean the drilling waste and push the waste generated by drilling to the opening of the collection box 10 for discharge.

[0021] Specifically, the clamping assembly includes an H-shaped mounting plate 15, which is fixedly installed in the middle position of the frame 1 near the top. A connecting rod 16 is rotatably installed at the top center of the H-shaped mounting plate 15, and connecting rods 17 are rotatably installed at both ends of the top of the connecting rod 16.

[0022] In this embodiment, an H-shaped mounting plate 15 is set as the basic mounting component of the clamping assembly and is fixedly installed in the middle position near the top of the frame 1. This provides a stable rotation mounting fulcrum for the connecting rod 16, ensuring that the connecting rod 16 can rotate flexibly around its top center position as an axis. The two ends of the top of the connecting rod 16 are respectively rotatably connected to the connecting rod 17, playing the role of connection and transmission. When one of the connecting rods 17 is subjected to a force from the clamping plate 18, the connecting rod 16 will rotate around the mounting point of the H-shaped mounting plate 15, thereby driving the connecting rod 17 at the other end to move synchronously, realizing the coordinated action of the two connecting rods 17, and providing transmission support for the symmetrical opening and closing of the clamping plate 18.

[0023] Specifically, the clamping assembly also includes two clamping plates 18, which are symmetrically arranged on the top of the connecting rod 17. The output end of the hydraulic cylinder 4 is fixedly installed on one side of one of the clamping plates 18, and the middle position of the bottom of the clamping plate 18 is rotatably installed on the other end of the connecting rod 17. Both ends of the clamping plate 18 are fixedly installed with L-shaped guide rods 19, and the other end of the L-shaped guide rods 19 is movably sleeved inside the guide groove 6.

[0024] In this embodiment, two clamping plates 18 are symmetrically arranged on the top of the connecting rod 17. One side of one clamping plate 18 is fixedly installed to the output end of the hydraulic cylinder 4. When the hydraulic cylinder 4 extends or retracts, it directly drives the clamping plate 18 to move. The middle position of the bottom of the clamping plate 18 is rotatably installed to the other end of the connecting rod 17, so that when the clamping plate 18 moves, it can drive the connecting rod 16 to rotate through the connecting rod 17, thereby driving the other clamping plate 18 to move synchronously in the opposite direction, realizing the symmetrical opening and closing of the two clamping plates 18, thereby stably clamping or releasing the hollow plate. The L-shaped guide rod 19 is fixedly installed on the clamping plate 18. The first end is movably fitted inside the guide groove 6, and cooperates with the guide groove 6 to guide and limit the movement of the clamping plate 18. When the clamping plate 18 moves under the drive of the hydraulic cylinder 4 and the connecting rod 17, the L-shaped guide rod 19 will slide along the trajectory of the guide groove 6, restricting the clamping plate 18 to move only in the direction of the guide groove 6, and preventing the clamping plate 18 from deviating or shaking during the movement. In addition, there is a certain distance between the clamping plate 18 and the bottom connecting rod 17. This distance can prevent the drilling metal rod from contacting the connecting rod 17 and the connecting rod 16 after passing through the hollow plate when drilling the hollow plate.

[0025] Specifically, the clamping assembly also includes two rectangular mounting slots 20, which are symmetrically opened at the bottom of the clamping plate 18. An L-shaped support plate 21 is rotatably mounted inside the rectangular mounting slots 20.

[0026] In this embodiment, two rectangular mounting slots 20 are symmetrically opened at the bottom of the clamping plate 18, providing installation space and rotation fulcrum for the L-shaped support plate 21. The slots can accommodate the L-shaped support plate 21 and allow it to rotate within the slots, ensuring that the L-shaped support plate 21 can be smoothly adjusted when clamping the hollow plate. The L-shaped support plate 21 is rotatably installed inside the rectangular mounting slots 20, initially in an inclined state. When the hollow plate is clamped, it will first contact the L-shaped support plate 21. As the clamping action proceeds, the L-shaped support plate 21 is squeezed by the side of the hollow plate and rotates to a vertical state within the rectangular mounting slots 20. At this time, the L-shaped support plate 21 can support the bottom of the hollow plate, and together with the clamping plate 18, it enhances the support for the hollow plate, prevents the hollow plate from shifting during drilling, and improves clamping stability. When the L-shaped support plate 21 rotates to the vertical state, it is flush with the bottom of the clamping plate 18 and will not hinder the normal operation of the clamping action.

[0027] Specifically, the clamping assembly also includes several first springs 22, the first springs 22 are fixedly installed on the inner top surface of the rectangular mounting groove 20, and the other end of the first springs 22 is fixedly installed on the side of the L-shaped support plate 21 near the bottom.

[0028] In this embodiment, one end of the first spring 22 is fixedly installed on the inner top surface of the rectangular mounting groove 20, and the other end is fixedly connected to the side of the L-shaped support plate 21 near the bottom end, so as to play an elastic reset role. When the hollow plate contacts the L-shaped support plate 21 and rotates it to a vertical state in the rectangular mounting groove 20, the L-shaped support plate 21 will stretch the first spring 22, so that the first spring 22 stores elastic potential energy. When the hollow plate is removed, the first spring 22 releases elastic potential energy and pulls the L-shaped support plate 21 to rotate and reset to the initial tilted state along the rotation point in the rectangular mounting groove 20.

[0029] Specifically, the collection and cleaning component includes a rotating rod 8, which is rotatably mounted between two L-shaped support rods 2. The end of the rotating rod 8 near the motor 7 is fixedly mounted to the output end of the motor 7, and a cam 9 is fixedly mounted at the middle position of the outer side of the rotating rod 8.

[0030] In this embodiment, the rotating rod 8 is rotatably installed between two L-shaped support rods 2, with its end near the motor 7 fixedly connected to the output end of the motor 7, and a cam 9 fixedly installed at the middle position on the outer side. When the motor 7 is working, the rotating rod 8 rotates around the mounting point between the two L-shaped support rods 2 under the drive of the motor 7, thereby driving the cam 9 to rotate synchronously and transmitting the power of the motor 7 to the cam 9.

[0031] Specifically, the collection and cleaning assembly also includes a collection box 10, which is fixedly installed inside the frame 1 and located at the bottom of the H-shaped mounting plate 15. One side of the collection box 10 is open, and an movable hole 13 is provided on the inner bottom surface of the collection box 10. Two second springs 12 are symmetrically fixedly installed on the inner bottom surface of the collection box 10 away from the open.

[0032] In this embodiment, the collection box 10 is fixedly installed inside the frame 1 and at the bottom of the H-shaped mounting plate 15. It is mainly used to collect waste generated during the drilling process. The movable hole 13 is opened on the inner bottom surface of the collection box 10. The top block 14 passes through the movable hole 13 and can move up and down along the movable hole 13, thereby driving the rectangular plate 11 to swing. The second spring 12 is symmetrically fixedly installed on the inner bottom surface of the collection box 10 away from the opening. The other end is fixedly connected to the bottom of the other end of the rectangular plate 11. When the rectangular plate 11 swings upward under the action of the cam 9 and the top block 14, the second spring 12 is stretched. When the cam 9 does not push the top block 14, the second spring 12 contracts and pulls the rectangular plate 11 back to its original position, so that the rectangular plate 11 can continue to swing back and forth to clean up the waste.

[0033] Specifically, the above-mentioned collection and cleaning assembly also includes a rectangular plate 11. One end of the rectangular plate 11 is rotatably installed at the bottom of the opening of the collection box 10. The top of the second spring 12 is fixedly installed at the bottom of the other end of the rectangular plate 11. A top block 14 is fixedly installed at the bottom of the rectangular plate 11. The top block 14 passes through the movable hole 13 and is used in conjunction with the cam 9. The external dimensions of the rectangular plate 11 are adapted to the internal space dimensions of the collection box 10. The rectangular plate 11 is set in an inclined state towards the opening of the collection box 10.

[0034] In this embodiment, one end of the rectangular plate 11 is rotatably mounted at the bottom of the opening of the collection box 10, allowing it to swing flexibly around the pivot point. The bottom of the other end is fixedly connected to the top of the second spring 12. The top block 14, fixedly mounted at the bottom, passes through the movable hole 13 and works in conjunction with the cam 9. Its external dimensions are adapted to the internal space dimensions of the collection box 10, fully covering the internal space of the collection box 10, and is set in an inclined state towards the opening of the collection box 10. When the cam 9 pushes the top block 14, the rectangular plate 11 swings upward around the pivot point, and the second spring 12 is stretched. When the cam 9 disengages from the top block 14, the second spring 12 contracts and pulls the rectangular plate 11 back to its original position. Through reciprocating swing, the waste in the collection box 10 is pushed towards the opening for discharge, thus achieving automatic waste cleaning.

[0035] In summary: When using this utility model, the hollow plate to be drilled is manually placed on the rectangular frame 5, positioned between the two clamping plates 18. At this time, the hollow plate first contacts the L-shaped support plate 21, which is initially tilted. Then, the motor 7 and hydraulic cylinder 4 connected to the external power supply are started. The hydraulic cylinder 4 begins to work, and its output end pushes one of the clamping plates 18, which is fixedly connected to it, to move. The bottom center of the clamping plate 18 is rotatably connected to the connecting rod 17, thus driving the connecting rod 17 to move. The other end of the connecting rod 17 is rotatably connected to the connecting rod 16, thereby driving the connecting rod 16 to rotate at the top center position of the H-shaped mounting plate 15. The connecting rod 16 then drives the other clamping plate 18 synchronously through the connecting rod 17 at the other end. The reverse movement achieves symmetrical closure of the two clamping plates 18. During this process, the L-shaped guide rods 19 at both ends of the clamping plates 18 slide along the guide groove 6 at the top of the rectangular frame 5, ensuring the smooth movement of the clamping plates 18. At the same time, the side of the hollow plate presses against the L-shaped support plate 21, causing it to rotate to a vertical position within the rectangular mounting groove 20, supporting the bottom of the hollow plate. The first spring 22 is stretched, working with the clamping plates 18 to firmly clamp the hollow plate. Subsequently, the control box of the drilling mechanism 3 controls the extension and retraction of the two hydraulic rods symmetrically fixed at its bottom, driving the adjusting plate and the drilling metal rod fixed in the adjusting hole of the adjusting plate by bolts to move up and down, performing a drilling operation on the firmly clamped hollow plate. Furthermore, due to the connection between the clamping plates 18 and the bottom connecting rod... There is a certain distance between the connecting rod 17 and the connecting rod 16. After the drilling metal rod passes through the hollow plate, it will not touch the connecting rod 17 and the connecting rod 16. The waste generated by drilling falls into the collection box 10 located at the bottom of the H-shaped mounting plate 15 under the action of gravity. At the same time, the output end of the motor 7 drives the rotating rod 8 to rotate between the two L-shaped support rods 2. The cam 9 at the middle position of the outer side of the rotating rod 8 rotates synchronously. When the cam 9 rotates to the point where the protruding part contacts the top block 14 that penetrates the movable hole 13 on the bottom surface of the collection box 10, it pushes the top block 14 to move upward. The top block 14 drives one end of the rectangular plate 11 fixed to it to swing upward around the rotation point at the bottom of the opening of the collection box 10. The other end of the rectangular plate 11 is connected to the second When spring 12 is stretched, and the cam 9 protrusion disengages from top block 14, the second spring 12 contracts and pulls rectangular plate 11 back to its original position. This process is repeated, and rectangular plate 11 swings up and down around its rotation point with the collection box 10. Since the rectangular plate 11 is adapted to the internal space of the collection box 10 and is tilted towards the opening, the waste in the collection box 10 can be pushed to the opening for discharge. After drilling is completed, motor 7 and hydraulic cylinder 4 are turned off. The output end of hydraulic cylinder 4 contracts and drives clamp 18 to loosen the hollow plate. At this time, the first spring 22 releases its elastic potential energy and pulls L-shaped support plate 21 to rotate and reset to its initial tilted state in rectangular mounting groove 20. Finally, the drilled hollow plate can be manually removed.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
