Description

Technical Field

[0001] This invention belongs to the field of galvanized steel pipe drilling technology, specifically referring to a galvanized steel pipe drilling device. Background Technology

[0002] In construction, municipal engineering, and other fields, the widespread application of galvanized steel pipes places high demands on their processing precision and efficiency. Drilling, a common process in galvanized steel pipe processing, is currently mostly performed using traditional bench drills or handheld equipment. Existing technologies have the following main drawbacks:

[0003] First, during drilling, especially when working on thin-walled galvanized steel pipes, the downward pressure applied by the drill bit can easily cause localized indentation or overall deformation of the pipe wall, severely affecting product quality. Existing fixing methods mostly rely on external clamping, which is insufficient to effectively resist internal deformation pressure.

[0004] Secondly, after drilling, metal burrs will inevitably be generated on the inner and outer edges of the hole. These burrs not only affect the appearance but also hinder the subsequent connection and installation of pipelines, and may even scratch construction workers. Currently, deburring is usually a separate subsequent process that requires operators to manually perform it using files, drill bits, or special tools. This significantly reduces overall processing efficiency, increases labor intensity and production costs, and the quality of deburring depends on the worker's skill level, making it difficult to maintain consistency.

[0005] In addition, the existing equipment has limited functionality. From fixing the steel pipe and drilling to deburring, it requires multiple clamping and tool changes, making the process cumbersome and with low automation, which makes it difficult to meet the unified requirements of efficiency and quality in modern construction.

[0006] Therefore, there is an urgent need in this field for a galvanized steel pipe processing device that integrates efficient fixing, precise drilling and automatic deburring to solve the problems of easy deformation of steel pipes, scattered processing steps and low efficiency in the existing technology.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] 1. Integrated internal support for deformation prevention and fixation: Through the synergistic effect of the fixed meshing cylinder entering the pipe opening and the adjusting stud driving the internal support rod to expand and press against the inner wall, rigid support is achieved from inside the steel pipe for the drilling position. This internal support method can effectively resist the radial force generated when the drill bit presses down, fundamentally preventing the galvanized steel pipe from denting or deforming during drilling, ensuring drilling quality and product structural integrity. At the same time, this internal support structure also plays a core fixing role, keeping the steel pipe stable during processing.

[0020] 2. Automated Deburring for Improved Efficiency and Quality: This invention creatively designs a deburring mechanism automatically triggered by the drilling feed action. Its core lies in the mechanical linkage generated by the relative displacement between the sleeve plate and the drill bit, which is generated by the relative displacement of the sleeve plate against the pipe wall. Through transmission components such as meshing gears, drive gears, and unidirectional rotating meshing gears, the semi-conical burr file is automatically triggered to pop out and perform the deburring action only at the moment when the drilling is completed and the drill bit is withdrawn from the hole. This design achieves seamless connection and automation of the two processes of drilling and deburring, completely eliminating the deburring steps of secondary clamping, tool changing and manual operation in the traditional process, greatly improving processing efficiency, reducing labor costs, and ensuring the consistency and reliability of the deburring effect.

[0021] 3. Adaptive fit for better deburring effect: The deburring mechanism, through the spherical pair composed of a universal ball and a shell, enables the file to automatically adjust at multiple angles after being inserted into the hole, ensuring that its working surface can fully fit the inner wall of the drill hole at different angles, thereby uniformly and thoroughly filing the burrs around the hole opening. It is more adaptable and the deburring effect is better than that of rigid fixed tools.

[0022] 4. Convenient operation and precise positioning: The equipment integrates multiple adjustment mechanisms such as scale lines, height adjustment electric actuators, and moving screws, making the placement, centering, and fine-tuning of the drilling position of the steel pipe very convenient and precise, reducing the difficulty of operation and ensuring the accuracy of the drilling position.

[0041] In practical use, place the galvanized steel pipe to be drilled on the anti-slip layer 57 on the drilling table 1, and adjust the drilling position near the pipe opening according to the scale line 58. Activate the height adjustment electric actuator 56, which raises and lowers the fixed engagement cylinder 46, aligning its axis with the axis of the galvanized steel pipe. Rotate the moving screw 55, which moves the engaging moving block 54 along the fixed frame 53. The moving moving block 54 moves the height adjustment electric actuator 56, which moves the fixed engagement cylinder 46 closer to the galvanized steel pipe, allowing it to enter the pipe. Rotate the adjusting stud 49, which moves the telescopic sleeve 4... 8. Telescopic movement: The telescopic sleeve 48 telescopically moves the hinge rod 50 to rotate. The rotation of the hinge rod 50 causes the inner support rod 51 to contract and expand until it presses against the inner wall of the galvanized steel pipe, providing internal support and preventing deformation while fixing the galvanized steel pipe. The feed motor 42 is started, and its rotation drives the feed screw 39 to rotate. The rotation of the feed screw 39 causes the fixed plate frame 34 to rise and fall, which in turn causes the drilling device 5 to rise and fall, achieving feed in the drilling direction. When the drill bit 36 ​​reaches the outer wall of the galvanized steel pipe, the sleeve plate 7 also reaches the outer wall of the galvanized steel pipe. The bottom end of the sleeve plate 7 is smooth (to prevent damage to the surface of the galvanized steel pipe). The drilling motor 37 is started, and its rotation drives the rotating seat 35 to rotate. The rotation of the rotating seat 35... The drill bit 36 ​​rotates and moves downwards to drill a hole in the galvanized steel pipe. At this time, the sleeve plate 7 abuts against the outer wall of the galvanized steel pipe. As the drill bit 36 ​​gradually moves downwards, the telescopic spring 9 contracts, the stabilizing telescopic rod 8 contracts, and the sleeve plate 7 moves upwards relative to the drill bit 36. Simultaneously, the fixed plate 13 moves upwards, causing the drive shaft 24 to move upwards. The drive shaft 24 then moves the meshing gear 23 upwards. Since the trigger rod 14 remains stationary, the meshing gear 23 rotates counterclockwise relative to the trigger rod 14. This counterclockwise rotation of the meshing gear 23 causes the drive shaft 24 to rotate counterclockwise, which in turn causes the drive gear 25 to rotate counterclockwise. The counterclockwise rotation of the drive gear 25 does not cause the unidirectional rotating meshing gear 18 to rotate. The unidirectional rotating meshing gear 18 only reciprocates along the rotating column 19 under the action of the spring 20, without rotating itself. Therefore, the rotating column 19 does not rotate, and the fixed buckle 17 does not rotate. The buckle plate 29 is fastened to the fixed buckle 17. After drilling is completed, the fixed plate frame 34 moves upward, driving the drilling device 5 to move upward. The drill bit 36 ​​gradually moves out of the galvanized steel pipe. At this time, the rotating seat 35 moves upward, driving the trigger rod 14 to move upward. Under the action of the telescopic spring 9, the sleeve plate 7 still presses against the outer wall of the galvanized steel pipe. When the drill bit 36 ​​moves upward into the sleeve plate 7, that is, when the drill bit 36 ​​disengages from the outer wall of the galvanized steel pipe, the trigger rod 14 moves upward, driving the meshing gear 23 to rotate clockwise.The clockwise rotation of the meshing gear 23 drives the drive shaft 24 to rotate clockwise, which in turn drives the drive gear 25 to rotate clockwise. This rotation of the drive gear 25 then drives the one-way rotating meshing gear 18 to rotate clockwise. The one-way rotating meshing gear 18 then drives the rotating column 19 to rotate clockwise, which in turn drives the fixed buckle plate 17 to rotate clockwise, thus disengaging it from the buckle plate 29. At this point, the limit spring 28 extends, the telescopic limit cylinder 27 extends, and the buckle plate 29 pops out downwards. The snap-fit ​​plate 29 pops out downwards, pushing the outer casing 30 downwards. The outer casing 30 then pushes the universal ball joint 33 downwards, which in turn pushes the connecting post 32 downwards. The connecting post 32 then pushes the semi-conical burr file 31 downwards, which inserts into the drilled hole. Under the automatic adjustment of the spherical pair formed by the universal ball joint 33 and the outer casing 30, the file conforms to the inner wall of the drilled hole, thereby removing the burrs at the hole opening. This is the specific working process of the present invention. This step can be repeated for subsequent uses.
