[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] An embodiment of the present application discloses a drilling device for a round pipe.

[0038] Example 1:

[0039] Reference Figure 1 and Figure 2 The drilling device includes a frame 1, a movable base 2, a drill bit 3, a drive member 4, and a limit assembly 5. The frame 1 is placed on the ground, the movable base 2 is slidably connected to one side of the frame 1, and the sliding direction is vertical. The drill bit 3 is fixedly connected to the lower end of the movable base 2. In this embodiment, the drive member 4 is an oil cylinder. In other embodiments, the drive member 4 can also be an air cylinder, an electric push cylinder, etc., which is not limited in this application. The drive member 4 is fixedly connected to the frame 1 on one side of the movable base 2, and the power output shaft of the drive member 4 is fixed to the upper end of the movable base 2 to drive the movable base 2 to slide.

[0040] Reference Figure 2 and Figure 3 The limiting assembly 5 includes a limiting column 51, wherein the limiting column 51 includes an abutting portion 511 and a sleeve portion 512. One end of the abutting portion 511 is fixedly connected to the frame 1, and the sleeve portion 512 is integrally connected to the other end of the abutting portion 511. The sleeve portion 512 is coaxially arranged with the abutting portion 511. The diameter of the sleeve portion 512 is adapted to the diameter of the circular tube 7 so that the circular tube 7 can be sleeved thereon, and the diameter of the sleeve portion 512 is smaller than the diameter of the abutting portion 511. At the same time, the sleeve portion 512 is located below the drill needle 3 and is provided with a clearance hole 513 for the drill needle 3 to pass through.

[0041] In actual use, the staff first sleeves one end of the circular tube 7 onto the sleeve portion 512. Since the diameter of the sleeve portion 512 is smaller than that of the abutment portion 511, the one end of the circular tube 7 abuts the abutment portion 511, while maintaining force on the circular tube 7 to achieve positioning and fixation of the circular tube 7. Next, the driving member 4 is activated, and the power output shaft of the driving member 4 drives the movable seat 2 downward, so that the drill bit 3 penetrates the circular tube 7 into the clearance hole 513 of the penetration portion to achieve positioning and drilling of the circular tube 7. During this process, the staff's force ensures that the circular tube 7 can be stably abutted against the abutment portion 511, which can effectively limit the displacement of the circular tube 7 during the drilling process, thereby effectively improving the drilling accuracy of the circular tube 7.

[0042] Reference Figure 1 and Figure 2 In some embodiments, the limit assembly 5 also includes a limit seat 52, which is fixedly connected to the frame 1 and is located below the sleeve portion 512. When the circular tube 7 is sleeved on the sleeve portion 512, the circular tube 7 abuts against the upper end of the limit seat 52, which can limit the rotation of the circular tube 7 and try to avoid the rotation of the circular tube 7 during the drilling process, thereby further improving the drilling accuracy of the circular tube 7 and improving the stability of the drilling.

[0043] In some embodiments, the limiting assembly 5 further includes two limiting wheels 53, which are spaced apart along the length of the limiting seat 52 and are rotatably connected to the upper end of the limiting seat 52, with their rotation axes being vertically arranged. When the circular tube 7 is sleeved on the sleeve portion 512, the circular tube 7 is abutted and limited between the two limiting wheels 53, thereby further limiting the rotation of the circular tube 7 and improving the drilling accuracy of the circular tube 7. At the same time, during the process of sleeved on the sleeve portion 512, each limiting wheel 53 contacts the circular tube 7 and rotates, thereby facilitating the sleeved installation of the circular tube 7 on the sleeve portion 512.

[0044] In some embodiments, the limit assembly 5 also includes a limit plate 54, which is fixedly connected to the upper end of the limit seat 52 and located at the upper end of the sleeve portion 512. When the circular tube 7 is sleeved in the sleeve portion 512, the circular tube 7 is abutted and limited between the limit plate 54 and the limit seat 52, which can further limit the rotation of the circular tube 7 and limit the displacement of the circular tube 7, thereby improving the drilling accuracy of the circular tube 7.

[0045] In some embodiments, there are two limit plates 54, and the two limit plates 54 are spaced apart along the width direction of the limit seat 52, so that the circular tube 7 can be more stably abutted and limited between the two limit plates 54 and the limit seat 52, and the drill needle 3 is located between the two limit plates 54 to ensure normal drilling of the circular tube 7.

[0046] The working principle of this embodiment is as follows: in actual application, the staff first sleeves one end of the circular tube 7 on the sleeve portion 512. Since the diameter of the sleeve portion 512 is smaller than the diameter of the abutment portion 511, the one end of the circular tube 7 abuts the abutment portion 511, while maintaining force on the circular tube 7 to achieve the positioning and fixation of the circular tube 7. Then, the driving member 4 is activated, and the power output shaft of the driving member 4 drives the movable seat 2 to move downward, so that the drill needle 3 penetrates the circular tube 7 to the clearance hole 513 of the penetration portion to achieve the positioning and drilling of the circular tube 7. During this process, the staff's force ensures that the circular tube 7 can be stably abutted against the abutment portion 511, which can effectively limit the displacement of the circular tube 7 during the drilling process, thereby effectively improving the drilling accuracy of the circular tube 7.

[0047] Example 2:

[0048] Reference Figure 4 This embodiment is identical to the first embodiment in other respects, with the difference being that a material receiving trough 521 is provided at the upper end of the stopper 52, located below the clearance hole 513. The material receiving trough 521 is arranged along the length of the stopper 52 and extends to one side of the stopper 52, so that one side of the stopper 52 has an opening 522. When the drill needle 3 is inserted into the circular tube 7, a metal sheet in the shape of the drill needle 3 is formed. The metal sheet falls from the clearance hole 513 into the material receiving trough 521 for collection, minimizing the possibility of metal sheets falling randomly into the stopper 52. At this time, the metal sheet in the material receiving trough 521 can be pushed out of the opening 522 of the stopper 52 by means of a workpiece.

[0049] In some embodiments, the drilling device also includes a cleaning component 6, which includes a cleaning block 61. The cleaning block 61 is slidably connected to the material receiving trough 521. By sliding the cleaning block 61, the cleaning block 61 contacts the metal sheet and pushes the metal sheet in the material receiving trough 521 out of the material receiving trough 521 to clean the metal sheet in the material receiving trough 521.

[0050] In some embodiments, the cleaning assembly 6 further includes a spring 62 and a latch 63. One end of the spring 62 is fixedly connected to the cleaning block 61, and the other end is fixedly connected to the end wall of the limiting seat 52 located at the receiving trough 521, so as to drive the cleaning block 61 to protrude from the receiving trough 521. At the same time, the latch 63 is provided through the limiting seat 52 and the cleaning block 61 to limit the sliding of the cleaning block 61. When it is necessary to clean the metal sheets in the receiving trough 521, the latch 63 is pulled out, causing the cleaning block 61 to slide under the drive of the spring 62, so that the cleaning block 61 protrudes from the receiving trough 521, thereby achieving automatic cleaning of the metal sheets in the receiving trough 521, which is simple and convenient to operate.

[0051] In some embodiments, a chamfer 611 is provided at one end of the cleaning block 61 away from the spring 62 , so that the cleaning block 61 can more fully contact the metal sheet, thereby making the cleaning block 61 more effective in cleaning the metal sheet in the receiving trough 521 .

[0052] In some embodiments, the cleaning assembly 6 further includes a sliding rod 64, which is fixedly connected to one end of the cleaning block 61 near the spring 62 and slidably connected to the stopper 52. This allows the cleaning block 61 to slide more stably, thereby improving the stability of metal sheet cleaning. Furthermore, the spring 62 is sleeved on the sliding rod 64, thereby minimizing bending damage to the spring 62 and thereby increasing the service life of the spring 62.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
