Description

Technical Field

[0001] This utility model relates to the field of door panel processing technology, and in particular to a drilling device for door panels. Background Technology

[0002] The main reasons for drilling holes during door panel processing include functional implementation, structural stability, and process compatibility. First, drilling is a necessary step for installing hardware accessories such as door locks and handles. Precise hole positioning ensures the proper operation of the linkage between the door lock and handle, while also meeting safety protection and daily opening and closing requirements. During drilling, the pressure of the drill rod and the vibration from rotation can cause the door panel itself to wobble, resulting in a drilled hole that is larger than the actual hole size, affecting subsequent processing and assembly.

[0003] A search revealed a Chinese patent publication number CN222245185U, which discloses a door panel drilling device, including an operating table, a bracket fixedly mounted on the operating table, a first cylinder mounted on the bracket, a lifting frame fixedly connected to the driving end of the first cylinder through the bracket, a first motor fixedly mounted on the lifting frame, a drill bit fixedly connected to the driving end of the first motor through the lifting frame, and four lifting rods movably mounted on the lifting frame.

[0004] To address the problem in the aforementioned technologies that not only are there sawdust particles above the door panel during drilling, but also a large amount of sawdust needs to be cleaned up below the door panel after drilling is completed, a drilling device for door panels is proposed.

[0005] In view of this, the present invention aims to provide a drilling device for door panels to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: it includes a bottom bracket and multiple lifting brackets.

One end of the transverse sliding screw is threadedly connected to a transverse sliding table, and the stabilizing rod is slidably connected to the transverse sliding table. A drilling motor is fixedly connected below the upper transverse sliding table, and a drill bit is fixedly connected to the power output end of the drilling motor. A top suction hood is slidably connected below the drilling motor, and a spring is fixedly connected to the top of the top suction hood and the lower end of the drilling motor. A lower suction hood is fixedly connected above the lower transverse sliding table, and a dust collection assembly is fixedly connected to one side of the lower suction hood and the top suction hood.

[0008] In some embodiments, the vacuuming assembly includes a vacuum pump, a vacuum hose one, and a vacuum hose two. The vacuum pump is fixedly connected to the bottom of a side sliding bracket. The vacuum hose one and a double-headed hydraulic rod are fixedly connected to the air inlet of the vacuum pump. The other end of the vacuum hose one is fixedly connected to the top suction hood, and the other end of the vacuum hose two is fixedly connected to the lower suction hood.

[0009] In some embodiments, a bevel gear is fixedly connected to one end of the transverse screw, and a bearing is rotatably connected to one end of the lifting bracket. A bevel gear ring is fixedly connected to the outside of the bearing, and the bevel gear ring and the bevel gear mesh with each other.

[0010] In some embodiments, a synchronous shaft is slidably connected inside the plurality of bearings. One end of the synchronous shaft is rotatably connected to the upper part of a translation bracket on one side.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0028] like Figures 1-5As shown, the door panel drilling device includes a bottom bracket 1 and multiple lifting brackets 9. The lifting brackets 9 can move up and down under the drive of other components. One end of each of the two lifting brackets 9 is rotatably connected to a transverse screw 13, and the other end of each lifting bracket 9 is fixedly connected to a stabilizing rod 14. One end of the transverse screw 13 is threadedly connected to a transverse slide 19, and the stabilizing rod 14 is slidably connected to the transverse slide 19. A drilling motor 20 is fixedly connected below the upper transverse slide 19, and a drill bit 23 is fixedly connected to the power output end of the drilling motor 20. A top suction cover 21 is slidably connected below the drilling motor 20. The top suction cover 21 is made of transparent plastic, and a spring 22 is fixedly connected to the top of the top suction cover 21 and the lower end of the drilling motor 20. A lower suction cover 25 is fixedly connected above the lower transverse slide 19. The lower suction cover 25 is made of hard rubber, and a dust collection component is fixedly connected to one side of the lower suction cover 25 and the top suction cover 21.

[0029] When the transverse screw 13 in the middle of the lifting brackets 9 on both sides rotates, it can drive the screw nut on the transverse slide 19 to move the transverse slide 19, and drive the drilling motor 20 to adjust the drilling position.

[0030] During drilling, the two transverse slides 19 move towards the center simultaneously, which clamps the door panel with the top suction hood 21 and the lower suction hood 25. The drilling motor 20 is then activated as the door panel moves towards the center. During this process, a large amount of wood chips are generated. The dust collection component is then activated, which simultaneously sucks up the dust and wood chips generated during drilling from the top suction hood 21 and the lower suction hood 25 on both sides. This ensures a clean working environment, reduces the impact of wood chips, and improves the drilling effect. Furthermore, the spring 22 compresses the top suction hood 21 and the lower suction hood 25 during drilling, which makes the door panel more stable near the drilling location and reduces the impact of vibration.

[0031] The vacuuming assembly includes a vacuum pump 10, a first vacuum pipe 24, and a second vacuum pipe 28. The vacuum pump 10 is fixedly connected to the bottom of a side sliding bracket 7. The first vacuum pipe 24 and the double-headed hydraulic rod 8 are fixedly connected to the air inlet of the vacuum pump 10. The other end of the first vacuum pipe 24 is fixedly connected to the top suction hood 21, and the other end of the second vacuum pipe 28 is fixedly connected to the lower suction hood 25.

[0032] The vacuuming assembly can use the vacuum pump 10 to suck up the dust and sawdust generated during drilling via vacuum hose 24 and vacuum hose 28.

[0033] In this embodiment, one end of each of the multiple lifting brackets 9 is fixedly connected to a double-headed hydraulic rod 8, the fixed end of the double-headed hydraulic rod 8 is fixedly connected to a translation bracket 7, one end of the slider below the translation bracket 7 is slidably connected to a side guide rail 6, and multiple side guide rails 6 are fixedly connected to both sides of the bottom bracket 1. The extension and retraction of both ends of the double-headed hydraulic rod 8 can drive the lifting brackets 9 on both sides to move inward and outward simultaneously.

[0034] Furthermore, the slider at the bottom of the translation bracket 7 can slide on the side guide rail 6, driving the upper double-headed hydraulic rod 8 to move and change its position to adjust the drilling position.

[0035] In this embodiment, a bevel gear 15 is fixedly connected to one end of the transverse screw 13, and a bearing 18 is rotatably connected to one end of the lifting bracket 9. A bevel gear ring 17 is fixedly connected to the outside of the bearing 18, and the bevel gear ring 17 and the bevel gear 15 mesh with each other.

[0036] A synchronous shaft 16 is slidably connected inside the multiple bearings 18. One end of the synchronous shaft 16 is rotatably connected to the upper part of the translation bracket 7 on one side. A transverse motor 11 is fixedly connected to the lower side of the translation bracket 7. The power output end of the transverse motor 11 is fixedly connected to the synchronous shaft 16.

[0037] The synchronous shaft 16 has bosses on both sides that match the slots on the inner side of the bearing 18, which can drive the two bearings 18 to rotate simultaneously. The rotating bearings 18 can drive the bevel gear 15 to rotate simultaneously through the external bevel gear ring 17, which in turn drives the transverse screws 13 on the upper and lower sides to rotate simultaneously, so that the drilling motor 20 and the lower suction hood 25 are in the same position, which is convenient for dust adsorption and clamping during drilling.

[0038] In this embodiment: When the transverse screw 13 in the middle of the lifting brackets 9 on both sides rotates, it can drive the screw nut on the transverse slide 19 to move the transverse slide 19, and drive the position of the drilling motor 20, which can be used to adjust the drilling position.

[0039] During drilling, the two transverse slides 19 move towards the center simultaneously, which clamps the door panel with the top suction hood 21 and the lower suction hood 25. The drilling motor 20 is then activated as the door panel moves towards the center. During this process, a large amount of sawdust is generated. The dust collection assembly is then activated, which simultaneously sucks up the dust and sawdust generated during drilling from the top suction hood 21 and the lower suction hood 25 on both sides. This ensures a clean working environment, reduces the impact of sawdust, and improves the drilling effect. Furthermore, the spring 22 compresses the top suction hood 21 and the lower suction hood 25 during drilling, which makes the door panel more stable near the drilling location and reduces the impact of vibration. The dust collection assembly can use the dust pump 10 to suck up the dust and sawdust generated during drilling through the first suction pipe 24 and the second suction pipe 28.

[0040] The extension and retraction of the two ends of the double-headed hydraulic rod 8 can drive the lifting brackets 9 on both sides to move inward and outward simultaneously; and the slider at the bottom of the translation bracket 7 can slide on the side guide rail 6, driving the double-headed hydraulic rod 8 above to move and change position to adjust the drilling position.

[0041] The synchronous shaft 16 has bosses on both sides that match the slots on the inner side of the bearing 18, which can drive the two bearings 18 to rotate simultaneously. The rotating bearings 18 can drive the bevel gear 15 to rotate simultaneously through the external bevel gear ring 17, which in turn drives the transverse screws 13 on the upper and lower sides to rotate simultaneously, so that the drilling motor 20 and the lower suction hood 25 are in the same position, which is convenient for dust adsorption and clamping during drilling. Example 2

[0042] The drilling device for the door panel is improved in this embodiment based on embodiment 1 as follows: Figures 1-5 As shown,

[0043] In this embodiment, a side support 5 is fixedly connected above the bottom support 1. Multiple rollers 2 are rotatably connected to one end of the side support 5, and multiple side rollers 3 are rotatably connected to one end of each side support 5. The rollers 2 are preferably electric models, which can drive the upper door panel to move, reducing the physical exertion of workers. The side rollers 3 can support the two sides of the door panel, allowing the middle part to be suspended for easy drilling and dust removal.

[0044] In this embodiment, a clamping telescopic rod 12 is fixedly connected above the bottom bracket 1, and drilling clamping rods 4 are fixedly connected to the movable ends on both sides of the clamping telescopic rod 12. The clamping telescopic rod 12 is a hydraulic type, which can drive the drilling clamping rods 4 on both sides to move inward simultaneously after retraction, clamping the door panel to prevent it from shaking during drilling.

[0045] In this embodiment, an air inlet 26 is provided on one side of the lower suction cover 25, and a buffer rubber ring 27 is fixedly connected to the edge of the lower suction cover 25. The air inlet 26 allows gas to enter when the door panel is not drilled, preventing the lower suction cover 25 from generating excessive negative pressure. The buffer rubber ring 27 is made of soft rubber, which can improve the fit between the upper part and the lower side of the door panel, preventing dust from leaking out.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
