Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a drilling device for the outer circumferential wall of a round tube. Background Technology

[0002] Traditional drilling of the outer circumference of round tubes relies primarily on manual operation. Workers manually place the tube on a makeshift workbench, without any internal support structure; the tube's support depends solely on its contact with the workbench surface. During drilling, workers must continuously rotate the tube manually to drill at different locations. This method presents several problems: First, poor positioning accuracy. Due to the lack of effective support and positioning structures, the tube is prone to wobbling and displacement during drilling, resulting in significant deviations in drilling position and angle, failing to meet high-precision machining requirements. Second, high labor intensity. Frequent manual rotation of the tube is not only physically demanding but also inefficient, making it unsuitable for large-scale production. Third, high safety risks. Workers' hands are close to the drilling area when manually rotating the tube, increasing the risk of workplace injuries should an error occur. Fourth, inconvenient waste disposal. Drilling debris easily accumulates in the work area, hindering drilling progress, causing wear on the drill bit and tube, shortening equipment lifespan, and increasing maintenance costs.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-6 This utility model provides the following technical solution: a drilling device for the outer circumferential wall of a circular tube, comprising a drilling machine, the drilling machine comprising a drilling platform 1, the drilling platform 1 being provided with a limiting fixture, the limiting fixture comprising a support table, a support shaft 4, a rotating ring 5, a turntable 6, a drive motor 7, a handle 8, and a limiting slide 9, the support table comprising a first support body 2 and a second support body 3, the first support body 2 being connected to and perpendicularly arranged with respect to the second support body 3, the second support body 3 being connected to the drilling platform 1, the first support body 2 having a fitting groove 10 adapted to the rotating ring 5, the rotating ring 5 being movably connected within the fitting groove 10, the support shaft... 4 is connected to the first support body 2. The support shaft 4 is located inside the rotating ring 5. The outer circumferential wall of the support shaft 4 is provided with a clearance groove 11. The limiting slide 9 is connected to the second support body 3. The limiting slide 9 is provided with a slide groove 12 that is adapted to the handle 8. The handle 8 is slidably connected in the slide groove 12. The drive motor 7 is installed on the handle 8. The drive shaft of the drive motor 7 is connected to the turntable 6. A push switch 13 is installed on the handle 8. A controller 14 is installed on the second support body 3. The controller 14 is connected to the push switch 13, the drive motor 7, and the drilling machine respectively through wires.

[0019] Using the above structure, the circular tube 21 can be securely held on the support shaft 4, providing precise positioning for drilling and ensuring the accuracy of the drilling start position. The operator moves the turntable 6 towards the circular tube 21 and presses the push switch 13, after which the controller 14 coordinates the drilling machine to complete a single drilling operation, ensuring that the drilling quality and depth meet the standards. After drilling is complete, the drive motor 7, under the control of the controller 14, drives the circular tube 21 to rotate at a set angle. The rotating ring 5 ensures smooth rotation of the circular tube 21, allowing drilling to continue at different positions on the outer circumference of the circular tube 21. The entire process is highly automated, reducing manual intervention, improving drilling efficiency and accuracy, and allowing for flexible adjustment of the drilling position according to different needs.

[0020] In this embodiment, movable shafts 15 are evenly distributed on the outer circumferential wall of the support shaft 4, and two of the movable shafts 15 are arranged adjacent to the clearance groove 11.

[0021] With the above structure, the movable shafts 15 evenly distributed on the outer circumference of the support shaft 4 further increase the support points for the round tube 21, making the installation of the round tube 21 on the support shaft 4 more stable. In particular, the two movable shafts 15 set near the clearance groove 11 can provide additional support in the critical drilling area, effectively preventing local deformation or displacement of the round tube 21 during drilling and rotation, and ensuring the accuracy of drilling position and angle.

[0022] In this embodiment, a waste chip channel 16 communicating with the clearance groove 11 is provided in the support shaft 4, and a waste chip outlet 17 is provided on the second support body 3.

[0023] With the above structure, the waste chips generated during drilling can enter the waste chip channel 16 inside the support shaft 4 through the clearance groove 11, and then be discharged from the waste chip outlet 17 on the second support body 3. This design avoids the accumulation of waste chips in the drilling area, prevents waste chips from causing wear to the drill bit and the round tube 21, ensures smooth drilling, and also extends the service life of the equipment and reduces equipment maintenance costs.

[0024] In this embodiment, a slider 18 is provided at one end of the support shaft 4 away from the limiting slide 9. The support shaft 4 is connected to the first support body 2 through the slider 18. A fixing block 19 is provided on the side of the first support body 2 away from the limiting slide 9. The fixing block 19 is connected to the slider 18 by bolts.

[0025] The above structure allows for flexible adjustment of the relative position between the clearance groove 11 and the drill bit. When dealing with different specifications of round pipes 21 or different drilling requirements, the operator can move the slider 18 to change the position of the support shaft 4, thereby placing the clearance groove 11 and the drill bit in the optimal relative position. This not only provides sufficient clearance space for the drill bit, preventing the support shaft 4 from interfering with it and ensuring smooth drilling operations, but also further improves drilling accuracy and efficiency. After adjusting the position, the slider 18 is securely fixed using the fixing block 19 and bolts, ensuring the stability of the support shaft 4 during drilling and rotation of the round pipe 21, providing a reliable guarantee for precise drilling.

[0026] In this embodiment, push switches 13 are provided on both the left and right sides of the handle 8.

[0027] The aforementioned structure requires operators to press the switch with both hands simultaneously for the device to operate. This design, from a safety perspective, prevents accidental activation due to single-handed operation, significantly reducing the risk of workplace injuries and providing reliable protection for operator safety.

[0028] In this embodiment, a weight-reducing groove 20 is provided on the support shaft 4.

[0029] With the above structure, the weight reduction groove 20 on the support shaft 4 reduces the overall weight of the device.

[0030] Working principle: The round tube 21 is placed on the support shaft 4. The round tube 21 is positioned and fixed by two movable shafts 15 evenly distributed on the outer circumference of the support shaft 4 and located near the clearance groove 11. Then, the operator moves the turntable 6 towards the round tube 21 by the handle 8 until it touches the round tube 21. At the same time, the operator presses the push switches 13 on both sides of the handle 8. After receiving the signal, the controller 14 coordinates the drilling machine to work. The drive motor 7 drives the turntable 6 to rotate, which in turn drives the drill bit to drill the round tube 21 in one pass. The waste chips generated during the drilling process enter the waste chip channel 16 in the support shaft 4 through the clearance groove 11 and are then discharged from the waste chip outlet 17 on the second support body 3. After one drilling is completed, the drive motor 7 drives the round tube 21 to rotate at a set angle under the control of the controller 14. The rotating ring 5 ensures that the round tube 21 rotates smoothly. After rotating to the appropriate position, the drilling operation is repeated. After all drilling is completed, the operator moves the handle 8 in the opposite direction to separate the turntable 6 from the round tube 21, releasing the resistance to the round tube 21, and finally removes the drilled round tube 21 from the support shaft 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
