[0049] In order to make the content of the present utility model easier to be clearly understood, the following further details the present utility model according to specific embodiments and in combination with the accompanying drawings.

[0050] As Figures 1 - 5 shown, a pipe drilling device includes:

[0051] a frame 1;

[0052] a mobile transmission mechanism 2, and the mobile transmission mechanism 2 is installed on the frame 1;

[0053] The pipe clamping mechanism 3 is installed on the moving transmission mechanism 2. A placement platform is provided on the pipe clamping mechanism 3, and the pipe clamping mechanism 3 is adapted to clamp and fix the pipe on the placement platform;

[0054] The moving transmission mechanism 2 is adapted to drive the pipe clamping mechanism 3 and the pipe on the pipe clamping mechanism 3 to move along the axial direction of the pipe;

[0055] The multi-bit linkage drilling mechanism 4 is installed on the frame 1, on one side of the frame 1. Four drill bit assemblies 45 facing one end of the pipe are provided on the multi-bit linkage drilling mechanism 4, and the multi-bit linkage drilling mechanism 4 is adapted to drive the four drill bit assemblies 45 to perform synchronous drilling at multiple points on one end of the pipe.

[0056] In this embodiment, as Figure 1 and Figure 5 shown, during use, first the pipe is conveyed to the placement platform of the pipe clamping mechanism 3. The pipe clamping mechanism 3 is activated to clamp and fix the pipe on the placement platform. Subsequently, the moving transmission mechanism 2 moves the pipe clamping mechanism 3 to the position of the multi-bit linkage drilling mechanism 4. The multi-bit linkage drilling mechanism 4 is activated to prepare for drilling on the pipe end face. The moving transmission mechanism 2 continues to move towards the position where the drill bit assemblies 45 are located. After the multi-bit linkage drilling mechanism 4 drills to the specified depth, the moving transmission mechanism 2 quickly retreats to withdraw from the drilling area. Then, the operator starts to clean the waste chips at the drilled part of the pipe. Next, the pipe clamping mechanism 3 is activated again to release the clamping of the pipe. Finally, the operator unloads the pipe from the placement platform to the specified area. This process is repeated in a cycle.

[0057] In some embodiments, the number of the drill bit assemblies 45 is not limited to four and can be set according to specific requirements.

[0058] The pipe can be various smooth solid-wall insulation pipes such as PE and PPR, etc., for axial drilling scenarios. This embodiment also includes a controller and a position sensor. The controller is electrically connected to the multi-bit linkage drilling mechanism 4, the moving transmission mechanism 2, the pipe clamping mechanism 3, and the position sensor respectively. The controller is responsible for coordinating the work of each component. It precisely controls the movement of the moving transmission mechanism 2 according to the real-time data provided by the position sensor to ensure that the pipe is always in the appropriate processing position. At the same time, the controller is also responsible for managing the operation of the multi-bit linkage drilling mechanism 4, including starting, stopping, and adjusting the drilling speed, etc. For the pipe clamping mechanism 3, the controller can automatically adjust the clamping force according to the characteristics of different pipes, ensuring both processing stability and avoiding damage to the pipe. The controller can specifically be a PLC, and the specific model of the PLC can be Siemens2000.

[0059] Specifically, as Figure 1 andFigure 5 As shown, the multi-bit linkage drilling mechanism 4 can have the following structure, including:

[0060] A drilling drive mechanism, which is fixed on the frame 1 and has a driving shaft on it;

[0061] A main swing arm 41, one end of which is installed on the driving shaft of the drilling drive mechanism;

[0062] A star-shaped connecting rod 42, which is rotatably installed on the other end of the main swing arm 41, and the star-shaped connecting rod 42 is provided with four connecting rods;

[0063] Four secondary swing arms 43, one end of each secondary swing arm 43 is hinged to the corresponding connecting rod of the star-shaped connecting rod 42;

[0064] A drill bit joint flange 44, which is fixed on the frame 1;

[0065] A drill bit assembly 45 is hinged on the drill bit joint flange 44. One end of the drill bit assembly 45 passes through the drill bit joint flange 44 and is fixedly connected to the other end of the corresponding secondary swing arm 43. A drill bit is provided at the other end of the drill bit assembly 45;

[0066] The drilling drive mechanism is adapted to drive the star-shaped connecting rod 42 to perform an eccentric motion through the rotation of the main swing arm 41, and then drive the four drill bit assemblies 45 and the drill bits of the drill bit assemblies 45 to rotate through the secondary swing arms 43.

[0067] Specifically, the drill bit is an integrated drilling and tapping drill bit.

[0068] In this embodiment, as shown in Figure 1 and Figure 5 , the drilling drive mechanism is connected to the main swing arm 41 through the driving shaft to output the initial motion for the main swing arm 41. The rotational motion of the main swing arm 41 is converted into the eccentric rotation of the star-shaped connecting rod 42. Finally, the star-shaped connecting rod 42 converts the eccentric rotation into the rotation of the drill bit through the secondary swing arms 43. The four connecting rods provided on the star-shaped connecting rod 42 enable the corresponding four drill bits to move synchronously, greatly improving the drilling efficiency. The drill bit joint flange 44 is fixed on the frame 1, providing a stable support point for the drill bit assembly 45 and allowing the drill bit assembly 45 to rotate freely on it. One end of the drill bit assembly 45 is fixedly connected to the secondary swing arm 43, and a drill bit is provided at the other end, enabling the drill bit to rotate and drill holes along with the movement of the drill bit assembly 45.

[0069] The drill bit assembly 45 includes a drill bit holder and four drill bits. The drill bit holder is hinged on the drill bit joint flange, passes through the drill bit joint flange and is fixedly connected to the other end of the corresponding secondary swing arm 43, and the drill bits are fixed on the corresponding drill bit holders.

[0070] In this embodiment, a drill-tap integrated bit is adopted. The drill-tap integrated bit can complete the tapping operation while drilling, eliminating the separate tapping process and greatly shortening the processing time.

[0071] In some embodiments, the number of connecting rods and auxiliary swing arms is not limited to four and can be set according to specific requirements.

[0072] Specifically, as Figure 5 shown, the drilling drive mechanism includes a reduction mechanism 46 and a drive source 47. The reduction mechanism 46 and the drive source 47 are installed on the frame 1;

[0073] The reduction mechanism 46 is provided with an input shaft and a driving shaft, and the driving shaft is connected to one end of the main swing arm 41;

[0074] The drive source 47 is provided with an output shaft, and the output shaft is connected to the input shaft of the reduction mechanism 46.

[0075] Specifically, as Figure 5 shown, the drive source 47 is a motor.

[0076] In this embodiment, as Figures 1 - 2 shown, the output shaft of the motor is connected to the input shaft of the reduction mechanism 46, which can convert the high-speed rotation of the motor into a low-speed and high-torque output more suitable for drilling operations. In addition, by adjusting the speed of the motor, it can adapt to different materials and thicknesses of pipes.

[0077] The specific model of the drilling drive mechanism can be an NMRV1.5KW motor.

[0078] Specifically, as Figures 1 - 2 shown, the moving transmission mechanism 2 can have the following structure, including:

[0079] A guide rail 21, which is fixed on the frame 1 along the axial direction of the pipe;

[0080] Two sliders 22, which are slidably arranged on the guide rail 21 and form a sliding fit with the guide rail 21;

[0081] The pipe clamping mechanism 3 is installed on the slider 22, and the pipe clamping mechanism 3 is provided with a connecting groove;

[0082] A telescopic drive mechanism 23, which is installed on the frame 1. The telescopic drive mechanism 23 is provided with a telescopic end, and the telescopic end is connected to the connecting groove.

[0083] Specifically, as Figures 1 - 2 shown, the telescopic drive mechanism 23 is a first cylinder.

[0084] In this embodiment, as Figures 1 - 2As shown, the moving transmission mechanism 2 enables the smooth movement of the pipe, effectively preventing shaking and deviation during movement, thereby ensuring the accuracy of the punching position. By adjusting the telescopic length of the first cylinder, it can not only adapt to pipes of different lengths, but also control the moving distance and speed of the pipe.

[0085] In some embodiments, the number of sliders 22 is not limited to two and can be set according to specific requirements.

[0086] The specific size model of the first cylinder can be SC63*150.

[0087] Specifically, as Figure 1 and Figure 3 shown, the pipe clamping mechanism 3 can have the following structure, including:

[0088] A base plate 31, which is installed on the moving transmission mechanism 2;

[0089] A clamping support frame 32, which is installed on the base plate 31;

[0090] A placement platform is arranged on the clamping support frame 32;

[0091] Two clamping arms 33, one end of each clamping arm 33 is hinged to the clamping support frame 32;

[0092] Two clamping driving sources 34, which are fixed on the frame 1, and each clamping driving source 34 is provided with a telescopic end, and the telescopic end is connected to the corresponding clamping arm 33;

[0093] The clamping driving source 34 is adapted to drive the corresponding clamping arm 33 to rotate around its hinge point to clamp the pipe placed on the clamping support frame 32.

[0094] Specifically, as Figure 1 and Figure 3 shown, the clamping support frame 32 is of a V-shaped structure, and the clamping arm 33 is provided with an inverted V-shaped structure corresponding to the clamping support frame 32.

[0095] Specifically, as Figure 3 shown, the clamping driving source 34 is a second cylinder.

[0096] In this embodiment, as Figures 1 - 2As shown, the pipe clamping mechanism 3 realizes the stable clamping and precise positioning of the pipe. The clamping support frame 32 adopts a V-shaped structure, providing a stable support surface for the pipe and being able to adapt to pipes of different diameters. The clamping arm 33 is designed with an inverted V-shaped structure, corresponding to the V-shaped structure of the clamping support frame 32. This design can better fit the circular outer surface of the pipe during the clamping process, improving the stability and uniformity of clamping. The clamping driving source 34 adopts a second cylinder, and its telescopic end is connected to the clamping arm 33, enabling precise control of the rotation angle and clamping force of the clamping arm 33. When it is necessary to clamp the pipe, the second cylinder extends, pushing the clamping arm 33 to rotate around its hinge point, thereby firmly clamping the pipe between the clamping support frame 32 and the clamping arm 33.

[0097] In some embodiments, the number of the clamping arms 33 and the clamping driving source 34 is not limited to two and can be set according to specific requirements. The specific size model of the second cylinder can be SC80*400.

[0098] Specifically, this embodiment further includes a height adjustment mechanism. Through the height adjustment mechanism, the center of the pipe can be adjusted to conform to the drilling position. The specific structure of the height adjustment mechanism can be a roller plus a height adjustment screw. The roller is rotatably arranged on the pipe clamping mechanism 3, providing additional support and stability for the pipe and facilitating the movement of the pipe. The roller bracket is fixed on the pipe clamping mechanism 3, and the height adjustment screw is vertically arranged on the roller bracket and forms a threaded connection with the roller bracket. The height of the roller can be precisely adjusted by rotating the screw.

[0099] In this embodiment, there can also be an automatic material turning device. The automatic material turning device mainly consists of a clamping support and a material turning driving device hingedly installed on the pipe clamping mechanism. The working process of the automatic material turning device can be as follows: When drilling is completed on one side of the pipe, the material turning driving device drives the clamping support to rotate, thereby driving the pipe to turn over and fall.

[0100] In this embodiment, when the pipe enters through the pipe clamping mechanism 3: 1. First, the clamping drive source 34, that is, the second cylinder, drives the clamping arm 33 to firmly fix the pipe on the clamping support frame 32; 2. Subsequently, the telescopic drive mechanism 23, that is, the first cylinder, drives the fixed pipe to move along the guide rail 21 to the position where the multi-bit linkage drilling mechanism 4 is located through the moving transmission mechanism 2; 3. The drive source 47 of the drilling drive mechanism is started to prepare for the drilling process. At the same time, the telescopic drive mechanism 23 continues to drive the pipe to move. The main swing arm 41 starts to rotate, driving the star-shaped connecting rod 42 to perform an eccentric motion, and then driving the four drill bit assemblies 45 and their drill-tap integrated drill bits to perform synchronous drilling operations on the end face of the pipe through the secondary swing arm 43; 4. When the drilling reaches the specified depth, the telescopic drive mechanism 23 quickly retracts, causing the pipe to move away from the drilling area; 5. At this time, the waste chips at the drilled part of the pipe can be cleaned. The clamping drive source 34 then releases the clamping arm 33; 6. The operator unloads the pipe that has completed drilling to the designated area. Then, the above steps are repeated to start the processing of the next pipe. During the whole process, if it is found that the center height of the pipe does not meet the drilling requirements, it can be manually adjusted through the height adjustment mechanism to adjust the pipe to the appropriate position.
