[0004] When drilling holes in curtain walls, the existing CNC drilling device for curtain wall production usually needs to drill holes on the surface of the profiles by a drill before they are spliced, because the curtain walls are mainly formed by splicing multiple long strips of profiles together, so as to facilitate assembly connection with other profiles. However, when drilling holes, a large amount of debris generated by the drill is splashed when drilling holes in the existing device, and part of it is easy to accumulate on the surface of the profile or on the device, causing obstruction and deviation of the device during the drilling process, thereby reducing the drilling accuracy of the device. Utility Model Content

[0005] The purpose of the present application is to solve the problem that debris is easily accumulated during the drilling process of the existing CNC drilling device for curtain wall production. The present application provides a CNC drilling device for curtain wall production.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0015] Furthermore, a sliding block is fixedly connected to the bottom of the hydraulic cylinder, and the sliding block is slidably connected to the moving plate.

[0016] By adopting the above technical solution, the hydraulic cylinder moves along the sliding plate, which improves the stability of the hydraulic cylinder when moving and makes the device more stable when clamping.

In the present application, when the device is processing, as the drill drives the cutter head to move toward the profile, the rubber cover also covers the drilling position of the profile, and at the same time the air pump starts to drive the suction pipe to suck air into the inside of the rubber cover, so that the debris dropped during the drilling process is sucked into the storage box by the suction pipe, so that the debris will not splash randomly during the processing of the device, reducing the problem of processing and drilling deviation caused by its accumulation, improving the safety of the device during use, and making the device easier to clean.

[0025] 2. In the present application, when the profile is to be installed on the device, one end of the profile is first pushed into the inclined plate. The sliding plate is squeezed by the profile and moves in the direction away from the limiting plate, so that the profile enters between the inclined plates. At this time, the spring reset pushes the sliding plate toward the profile, thereby clamping the two sides of the profile, so that the profile is limited by multiple end points during the processing, thereby improving the stability of drilling. When the profile moves, the force of the spring is not enough to stop the movement of the profile, which will make the movement of the profile more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a CNC drilling device for curtain wall production.

[0035] When the device is used to drill holes in profiles on the curtain wall, the profiles are first placed on the movable plate 14, and then clamped by the clamping structure, and then the drill 3 is started to drive the cutter head 21 to drill holes in the profiles. While drilling, the absorption structure will cover the drilling position, reducing the splashing of debris during drilling and collecting the debris, so that the device is less affected by the splashing debris during the processing, thereby enhancing the safety of the device during processing and making the device easier to clean during processing.

[0036] Reference Figure 2 The absorption structure includes a rubber cover 4 fixedly connected to the outside of the drill bit 3, the rubber cover 4 is adapted to the drill bit 3, an air intake pipe 5 is fixedly connected between the frame 1 and the rubber cover 4, a mounting frame 7 is fixedly connected to one side of the frame 1, an air pump 6 is fixedly connected to one end of the air intake pipe 5 away from the rubber cover 4, a storage box 8 is slidably arranged in the mounting frame 7, an air outlet end of the air pump 6 is connected to the storage box 8, and an opening is arranged on the top of the storage box 8.

[0037] When the device is processing, as the drill 3 drives the cutter head 21 to move toward the profile, the rubber cover 4 also covers the drilling position of the profile. At the same time, the air pump 6 starts to drive the suction pipe 5 to suck air into the rubber cover 4, so that the debris dropped during the drilling process is sucked into the storage box 8 by the suction pipe 5, so that the debris will not splash randomly during the processing of the device, reducing the problem of processing and drilling deviation caused by its accumulation, improving the safety of the device during use, and making the device easier to clean.

[0038] Reference Figure 3 and Figure 4 The clamping structure includes a fixed plate 15 fixedly connected to the top of one side of a moving plate 14, and a hydraulic cylinder 18 is slidably connected to the moving plate 14. The telescopic end of the hydraulic cylinder 18 and one side of the fixed plate 15 are fixedly connected with a buffer pad 16, and the buffer pad 16 is a rubber pad. A clamping motor 17 is fixedly connected to one side of the moving plate 14, and a clamping threaded rod 22 is fixedly connected to the output end of the clamping motor 17. The clamping threaded rod 22 is rotatably connected to the moving plate 14, and the clamping threaded rod 22 is threadedly connected to the bottom of the hydraulic cylinder 18. A sliding block 23 is fixedly connected to the bottom of the hydraulic cylinder 18, and the sliding block 23 is slidably connected to the moving plate 14. A moving motor 9 is fixedly connected to one side of the frame 1, and a moving threaded rod 19 is fixedly connected to the output end of the moving motor 9, and the moving threaded rod 19 is threadedly connected to the moving plate 14;

[0039] Both ends of the sliding column 20 are fixedly connected to the mounting plate 10, one side of the mounting plate 10 is fixedly connected to the limit plate 12, the mounting plate 10 is slidably connected to the sliding plate 11, and the corresponding sides of the sliding plate 11 and the limit plate 12 are fixedly connected to the inclined plate 13, which is a rubber plate. A fixed column 24 is fixedly connected inside the mounting plate 10, and the fixed column 24 is slidably connected to the sliding plate 11. A spring 25 is sleeved on the fixed column 24, and the two ends of the spring 25 are fixedly connected to the sliding plate 11 and the mounting plate 10 respectively.

[0040] When the device is processing, the part of the profile that needs to be punched is first placed on the movable plate 14, and then one side of it is fitted with the fixed plate 15, and then the hydraulic cylinder 18 is started to drive the buffer plate to clamp it from both sides of the profile. When the size of the profile is different from that on the movable plate 14, the clamping motor 17 can be started to drive the clamping threaded rod 22 to rotate, so that the hydraulic cylinder 18 moves on the movable plate 14 along the sliding plate 11, thereby adjusting its clamping distance to the profile. After processing one part of the profile, the mobile motor 9 is started to drive the mobile threaded rod 19 to rotate, so that the movable plate 14 moves along the sliding column 20, thereby adjusting the drilling position of the drill 3, so that the device can be suitable for processing profiles of different sizes.

[0041] When the profile is to be installed on the device, one end of the profile is first pushed into the inclined plate 13. The sliding plate 11 is squeezed by the profile and moves away from the limiting plate 12, so that the profile enters between the inclined plates 13. At this time, the spring 25 is reset to push the sliding plate 11 to move toward the profile, thereby clamping the two sides of the profile, so that the profile is limited by multiple end points during the processing, thereby improving the stability of drilling. When the profile moves, the force of the spring 25 is not enough to stop the movement of the profile, which makes the movement of the profile more stable.

[0042] Working principle: When the device is used to drill holes in profiles on the curtain wall, when the profile is to be installed on the device, one end of the profile is first pushed into the inclined plate 13, and the sliding plate 11 is squeezed by the profile and moves away from the limiting plate 12, so that the profile enters between the inclined plates 13. At this time, the spring 25 is reset to push the sliding plate 11 to move toward the profile, thereby clamping both sides of the profile, so that the profile is limited by multiple end points during the processing, thereby improving the stability of drilling;

[0043] Place the part of the profile that needs to be punched on the mobile plate 14, and then fit one side of it with the fixed plate 15, and then start the hydraulic cylinder 18 to drive the buffer plate to clamp the profile from both sides. When the size of the profile is different from that on the mobile plate 14, the clamping motor 17 can be started to drive the clamping threaded rod 22 to rotate, so that the hydraulic cylinder 18 moves along the sliding plate 11 on the mobile plate 14, thereby adjusting its clamping distance for the profile. After processing one part of the profile, start the mobile motor 9 to drive the mobile threaded rod 19 to rotate, so that the mobile plate 14 moves along the sliding column 20, thereby adjusting the drilling position of the drill 3;

[0044] When the device is processing, as the drill 3 drives the cutter head 21 to move toward the profile, the rubber cover 4 also covers the punching position of the profile. At the same time, the air pump 6 starts to drive the suction pipe 5 to suck air into the rubber cover 4, so that the debris dropped during the drilling process is sucked into the storage box 8 by the suction pipe 5, so that the debris will not splash randomly during the processing of the device.
