[0026] It should be noted that like reference numerals and letters refer to like items in the several views, and as a result, further specific discussion and description of such items need not be repeated in the description of the subsequent views.

[0027] To solve the technical problems in the background art, as shown in the description Figures 1-5 The present application provides a technical solution: a stainless steel pipe drilling machine, characterized by:

[0028] The frame 1 is the foundation of the entire drilling machine, used to support and fix all components. It is usually made of solid steel to ensure stability and durability during operation. The clamping device 2 is installed on the frame 1 and is used to fix the stainless steel pipe. The device includes two oppositely arranged clamping blocks 3, which can clamp the pipe. The bottom of the clamping block 3 is provided with a screw bearing 4, which is matched with a screw rod 5 fixed on the frame 1 to realize the precise movement of the clamping block 3. The inner wall of the clamping block 3 is designed with an arc surface 7 to adapt to pipes of different diameters. The air cylinder 6 is fixed on the frame 1 and connected with the side of the clamping block 3. By the extension and contraction of the air cylinder 6, the clamping block 3 is driven to slide along the screw rod 5, realizing the opening and closing action of the clamping block 3. The extension plate 8 is connected to the frame 1 and located at the upper end of the clamping block 3. The extension plate 8 is provided with a sliding rail 9 in the middle for guiding the movement of the sliding block 11. The hydraulic cylinder 10 is installed in the middle of the extension plate 8, and the end of its extension rod is connected with the sliding block 11. The sliding block 11 is sleeved on the sliding rail 9 and can slide along the sliding rail 9 under the drive of the hydraulic cylinder 10. The drill bit 12 is installed on the sliding block 11 and faces the clamping block 3. The drill bit 12 moves with the sliding block 11 along the sliding rail 9 to complete the drilling work.

[0029] In use, the stainless steel pipe is placed between the two clamping blocks 3 of the clamping device 2. The position of the clamping block 3 is adjusted by the cooperation of the screw rod 5 and the air cylinder 6. The air cylinder 6 drives the clamping block 3 to clamp the pipe, ensuring that the pipe is located at the predetermined drilling position. The hydraulic cylinder 10 drives the sliding block 11 to move along the sliding rail 9, moving the drill bit 12 to the predetermined drilling position of the pipe. The drill bit 12 is started to perform drilling operation. The drill bit 12 is accurately moved along the sliding rail 9 under the drive of the sliding block 11 to drill the pipe. After drilling is completed, the hydraulic cylinder 10 drives the sliding block 11 to return to the original position, and the air cylinder 6 releases the clamping block 3 to loosen the pipe. Finally, the processed pipe is taken out from the clamping device 2, completing the entire drilling process.

[0030] It should be noted that the rolling plate 13 is arranged on the side of the clamping block 3 and located on the symmetry axis of the two clamping blocks 3. Such design makes the rolling plate 13 play a key role in the process of loading and unloading the pipe, reduces friction and allows the pipe to move easily. The rolling plate 13 has a cavity 14 inside, which is designed to accommodate the rolling shaft 15 and the roller 16, keeping the structure compact while providing the necessary space for the rolling shaft 15 and the roller 16. A plurality of parallel rolling shafts 15 are arranged in the cavity 14. The rolling shaft 15 is the core component of the rolling plate 13, which is arranged in parallel to ensure the stability and consistency of the pipe movement. Each rolling shaft 15 is sleeved with a roller 16. The roller 16 contacts the pipe and provides a low-friction rolling contact surface, reducing the resistance when clamping and moving the pipe, while also protecting the surface of the pipe from being scratched.

[0031] Further, the support frame 17 is arranged on the rack 1 and shares the same symmetry axis with the clamping device 2. Such design enables the support frame 17 to stably support one end of the pipe and ensures the symmetry and balance of the entire drilling process. The side of the support frame 17 facing the clamping device 2 is provided with a supporting plate 18. The supporting plate 18 serves as a stable support platform for the pipe, ensuring its stability during clamping and drilling, and preventing the end of the pipe from sagging or deviating under the action of gravity.

[0032] It should be noted that the support frame 17 is fixed on the rack 1 and arranged on the same symmetry axis as the clamping device 2, providing a stable support structure. Inside the support frame 17 is provided with a sliding groove 19, which is a channel for guiding the movement of the sliding block 20, ensuring that the supporting plate 18 can move smoothly in the vertical direction. The supporting plate 18 is fixed on the support frame 17 and faces the clamping device 2, used to support the pipe. The bottom of the supporting plate 18 is connected with the sliding block 20, allowing the supporting plate 18 to move up and down along the screw shaft 22. The sliding block 20 is fixed at the bottom of the supporting plate 18 and passes through the sliding groove 19, cooperating with the rolling bearing 21 to realize the vertical movement of the supporting plate 18. The rolling bearing 21 is sleeved on the screw shaft 22 and adapts to the screw shaft 22, reducing the friction when the supporting plate 18 moves along the screw shaft 22 and improving the smoothness and accuracy of the movement. The two ends of the screw shaft 22 are connected to the support frame 17, forming the track of the supporting plate 18. The screw shaft 22 is sleeved with the rolling bearing 21 to ensure that the supporting plate 18 can slide smoothly up and down.

[0033] Further, the rotating disc 23 is arranged at the top end of the lead screw shaft 22 as a driving and operating interface, so that the operator can more easily drive the lead screw shaft 22. The rotating disc 23 can be designed in the form of a handle or a gear to facilitate manual or powered driving. The addition of the handle or the gear can amplify the force exerted by the operator, making the rotation of the lead screw shaft 22 more effortless. The rotating disc 23 is directly connected to the top end of the lead screw shaft 22, which can be a mechanical connection in the form of a keyway, spline or thread, to ensure stability and reliability when transmitting power.

[0034] It should be noted that the adjusting block 24 is arranged at the bottom of the support frame 17 for adjusting the position of the support frame 17, ensuring the precise fit and stability between the support frame 17 and the clamping device 2. The guide rail 25 is arranged at the top of the rack 1, providing a sliding path so that the support frame 17 can move horizontally along the guide rail 25. The adjusting block 24 can be designed with multiple mounting slots that fit the corresponding slots on the guide rail 25, allowing the adjusting block 24 to move flexibly on the guide rail 25 and stop at different positions.

[0035] It should be noted that the pulley assembly 26 is an important component connecting the motor 29 and the adjusting screw 27, which can transmit the rotary motion of the motor 29 to the adjusting screw 27 to realize the rotation of the adjusting screw 27. The adjusting screw 27 is a threaded rod that passes through the threaded hole 30 in the adjusting block 24 and the fixed seat 28, used to adjust the position of the adjusting block 24. The rotation of the adjusting screw 27 will cause the adjusting block 24 to move axially along the adjusting screw 27. The fixed seat 28 is used to fix one end of the adjusting screw 27, ensuring that the adjusting screw 27 does not deviate when rotating, and at the same time serving as a support structure for the adjusting screw 27. The motor 29 is the power source of the entire adjustment system, which drives the pulley assembly 26 to rotate, and then drives the adjusting screw 27 to rotate. The pulley wheel 31 is part of the pulley assembly 26, connected to the adjusting screw 27, which transmits the rotary motion of the pulley assembly 26 to the adjusting screw 27.

[0036] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
