Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a drilling device for power tower production with adjustable angle, including a frame 1 and a lead screw 3. A first motor 2 for driving the lead screw 3 is provided above the frame 1. The lead screw 3 and a slider 4 are threadedly connected and the slider 4 is slidably connected to the inside of the frame 1. A drive rod 5 is provided below the slider 4 and is located in a moving groove inside the frame 1. A processing groove 7 is provided on the frame 1. Two sets of assembly plates 6 are slidably connected inside the processing groove 7. The assembly plate 6 on the side of the processing groove 7 near the drill bit 16 is fixedly connected to the lower end of the drive rod 5. The two sets of assembly plates 6 are connected by bolts and brush plates 8 on both sides. Wastewater collection tanks 21 are provided on both sides of the frame 1. Two guide channels 20 are provided inside the processing groove 7. The guide channels 20 penetrate the processing groove 7 and one end of the guide channels 20 is located inside the wastewater collection tank 21. A filter screen plate 22 is slidably connected inside the wastewater collection tank 21.

[0021] During drilling, the first motor 2 drives the lead screw 3 to rotate, causing the lead screw 3 to drive the upper slider 4 to slide inside the frame 1. The slider 4 then drives the assembly block 9 to slide above the frame 1, allowing the position of the drill bit 16 to be adjusted for drilling at different locations on the workpiece surface. While the drill bit 16 is moving, the slider 4 drives the assembly plate 6 to slide inside the frame 1 via the drive rod 5. This causes the assembly plate 6 to move synchronously with the brush plate 8. The brush plate 8 sweeps the waste chips and coolant generated during drilling inside the processing groove 7 to both sides, promoting the waste chips and coolant to enter the wastewater collection tanks 21 on both sides through the guide channels 20. After entering, the wastewater passes through the filter screen 22 to separate the waste chips and coolant, facilitating coolant recovery.

[0022] An assembly block 9 is positioned above the slider 4. Inside the assembly block 9 is a lifting assembly 11 for raising and lowering the drill bit 16. The lifting assembly 11 includes a stepper motor 111, a rotating shaft 112, a gear 113, a rack 114, and guide bars 115. The assembly block 9 is equipped with a stepper motor 111 for driving the rotating shaft 112. The rotating shaft 112 is mounted with a gear 113. A rack 114 for meshing with the gear 113 is mounted on a fixed block 12. Two sets of guide bars 115 are mounted on the fixed block 12, and the guide bars 115 are slidably connected to the assembly block 9. A fixed block 12 is located at the front end of the assembly block 9. An adjustment assembly 10 for adjusting the angle of the drill bit 16 is provided above the fixed block 12. The adjustment assembly 10 includes a semi-worm gear 101, a semi-circular slide groove 102, a drive block 103, a second motor 104, and a worm gear 105. The semi-worm gear 101 is fixedly installed below the fixed block 12. Two sets of semi-circular slide grooves 102 are provided below the fixed block 12. The inner side of the semi-circular slide groove 102 is fixedly connected to both sides of the semi-worm gear 101. The drive block 103 is slidably connected inside the semi-circular slide groove 102. An adjustment block 13 is provided below the drive block 103. An installation block 14 is provided below the adjustment block 13. A mounting block 14 is provided above the installation block 14. A coolant nozzle 17 is provided for cooling the drill bit 16. The coolant nozzle 17 is connected to an external water supply system. A drive motor 15 is mounted on the mounting block 14 with bolts. The output end of the drive motor 15 is fitted with the drill bit 16. A second motor 104 for driving the worm gear 105 is provided on the adjusting block 13. The worm gear 105 and the half-worm wheel 101 work together. The worm gear 105 is located inside the adjusting block 13. The adjusting block 13 is located below the fixing block 12. The drill bit 16 is located below the adjusting block 13. A soft anti-splash membrane 18 is installed on the adjusting block 13. The machining groove 7 is provided with a coolant spray nozzle for cooling the drill bit 16. The fixing assembly 19 for fixing the workpiece includes a placement plate 191, a cylinder 192, a connecting rod 193, and a clamping block 194. Multiple sets of placement plates 191 are arranged inside the processing groove 7. Two sets of clamping blocks 194 are arranged above the placement plates 191. The clamping block 194 on the upper side of the placement plate 191 is slidably connected to the placement plate 191, and the clamping block 194 on the other side is fixedly connected to the upper side of the placement plate 191. Two sets of cylinders 192 are arranged inside the processing groove 7. A drive rod 5 is arranged at the front end of the cylinder 192. The drive rod 5 is connected to the clamping block 194 on the upper side of the placement plate 191.

[0023] During use, the workpiece to be drilled is placed above the placement plate 191 inside the machining tank 7. The cylinder 192 inside the machining tank 7 drives the connecting rod 193 to move. Simultaneously, the connecting rod 193 drives the clamping block 194 to slide above the placement plate 191, causing the clamping blocks 194 on both sides of the placement plate 191 to cooperate and fix the workpiece. During use, the stepper motor 111 drives the rotating shaft 112 to rotate, causing the rotating shaft 112 to drive the upper gear 113 to rotate. Simultaneously, the gear 113 drives the rack 114 to move. At this time, the rack 114 drives the fixing block 12 to descend, and the guide bar 115 above the fixing block 12 slides inside the assembly block 9. The drill bit 16 descends below, and the drive motor 15 is activated to drive the drill bit 16 to rotate. The drill bit 16 then contacts the workpiece below and drills a hole. During drilling, the coolant nozzle 17 sprays external coolant onto the drill bit 16 to cool it and prevent overheating. Meanwhile, during the drilling process, there will be waste chips. The soft anti-splash film 18 on the surface of the adjusting block 13 can prevent the waste chips from splashing. Since the anti-splash film 18 is made of transparent material, it is easy to observe during the drilling process. At the same time, during the drilling process, the second motor 104 can drive the worm gear 105 to rotate, so that the worm gear 105 moves around the semi-worm wheel 101. At the same time, the worm gear 105 drives the adjusting block 13 to slide inside the semi-circular slide groove 102 in conjunction with the drive block 103, so that the angle of the drill bit 16 below can be adjusted, which makes it convenient to drill the workpiece surface at different angles.

[0024] Working principle: When using the drilling device for power tower production with adjustable angle, the workpiece to be drilled is placed above the placement plate 191 inside the processing tank 7. Then, the cylinder 192 inside the processing tank 7 drives the connecting rod 193 to move. At the same time, the connecting rod 193 drives the clamping block 194 to slide above the placement plate 191, so that the clamping blocks 194 on both sides above the placement plate 191 cooperate to fix the workpiece. During use, the stepper motor 111 drives the rotating shaft 112 to rotate, which drives the gear 113 above to rotate. At the same time, the gear 113 drives the rack 114 to move. At this time, the rack 114 drives the fixing block 12 to descend. At the same time, the guide bar 115 above the fixing block 12 slides inside the assembly block 9. At this time, the drill bit 16 below descends. At the same time, the drive motor 15 is started to drive the drill bit 16 to rotate. The drill bit 16 contacts the workpiece below and drills the workpiece. During drilling, the coolant nozzle 17 sprays external coolant onto the drill bit 16 to cool it and prevent overheating. Simultaneously, during drilling, debris is generated; the soft anti-splash film 18 on the surface of the adjusting block 13 prevents debris from splashing. Since the anti-splash film 18 is transparent, it is easy to observe during drilling. During drilling, the second motor 104 drives the worm gear 105 to rotate, causing it to move around the semi-worm wheel 101. The worm gear 105 also drives the adjusting block 13, in conjunction with the drive block 103, to slide within the semi-circular groove 102, allowing for angle adjustment of the drill bit 16. This facilitates drilling at different angles on the workpiece surface. During drilling, the first motor 2 drives the lead screw 3 to rotate, causing the lead screw 3 to drive the upper slider 4 to slide within the frame 1. The slider 4 then drives the assembly block 9 to slide above the frame 1, allowing for adjustment of the drill bit 16's position and facilitating drilling at different locations on the workpiece surface. During the movement of the drill bit 16, the slider 4 drives the assembly plate 6 to slide inside the frame 1 via the drive rod 5. This causes the assembly plate 6 to move synchronously with the brush plate 8. The brush plate 8 sweeps the waste chips and coolant generated during drilling inside the machining groove 7 to both sides, promoting the waste chips and coolant to enter the wastewater collection tanks 21 on both sides through the guide channels 20. After the waste liquid enters, it passes through the filter screen plate 22 to separate the waste chips and coolant, facilitating the recovery of the coolant. This completes a series of operations. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
