[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a steel pipe drilling device. Background Technology

[0002] In modern livestock farming, steel pipes are widely used in key structural components such as drinking water pipelines, feed line supports, pen posts, ventilation ducts, and manure scraper guide rails. According to relevant national and industry standards, these steel pipes need to have a large number of installation holes pre-drilled in the factory to facilitate the quick insertion of nipple drinkers, sensors, corner wheels, hanging rings, and various fasteners.

[0003] Existing drilling devices generally adopt a simple two-end support or single-point support structure: the steel pipe is placed horizontally on a V-shaped support frame, and the drill bit drills from top to bottom in the middle of the pipe. Since the position of the roller frame is fixed, the length of the suspended section of the steel pipe is usually 1m to 1.5m. Thin-walled pipes have low bending stiffness and are subjected to concentrated radial force at the moment of punching. When subjected to force, the steel pipe may jump or sway to the side, resulting in obvious deflection and causing the hole position to shift. Summary of the Invention

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following description, in conjunction with the accompanying drawings, describes a steel pipe drilling device according to an embodiment of the present invention.

[0018] like Figures 1-3 The steel pipe drilling device of this utility model embodiment may include a support platform 1, a support component 2, a connecting component 3, and a fixing component 4.

[0019] It should be noted that the support platform 1 is used to support the device and is parallel to the ground.

[0020] Among them, the support component 2 is installed on the upper front side of the support platform 1. The support component 2 is used to provide follow-up support on the lower side of the steel pipe. During drilling, the radial pressure acting on the steel pipe is directly transmitted to the support platform 1 through the support component 2, thereby avoiding the thin-walled steel pipe from bending or breaking due to excessive suspension span.

[0021] The connecting component 3 is installed on the upper end of the support platform 1 and connected to the support component 2. The connecting component 3 drives the support component 2 to move according to the drilling position. The connecting component 3 drives the support component 2 to move laterally, so that the support component 2 is always positioned directly below the drill bit in real time.

[0022] Two sets of fixing components 4 are installed. The two sets of fixing components 4 are symmetrically installed on both sides of the upper end of the support platform 1. During drilling, the two sets of fixing components 4 simultaneously clamp and fix the two ends of the steel pipe, so that the steel pipe always remains horizontal and taut, preventing jumping, twisting or axial displacement due to radial force at the moment of punching, thereby ensuring the accuracy of the hole position and protecting the thin-walled pipe from damage.

[0023] The fixing component 4 includes: a support frame 41, a support roller 42, and a pressing component 43. The support frame 41 is fixedly connected to both sides of the upper end of the support platform 1 and is arranged symmetrically. Its lower internal end is V-shaped, providing stable support and clamping reference for both ends of the steel pipe.

[0024] In an embodiment of this utility model, two support rollers 42 are rotatably connected to the lower end of a single support frame 41 via bearings and are located on both sides of a V-shaped opening, jointly providing rolling support for the steel pipe. After the steel pipe is placed on the upper end of the support frame 41, it is fed axially with low friction by means of the rotatable support rollers 42. The outer surface of the support rollers 42 is made of wear-resistant rubber, forming an elastic buffer to avoid direct metal-to-metal contact.

[0025] The pressing assembly 43 is installed inside the support frame 41 and can move up and down in the vertical direction to press the steel pipe against the support roller 42 or release it upward.

[0026] In one embodiment of this utility model, such as Figure 4 As shown, the pressure holding assembly 43 includes a pressure block 431, a buffer plate 432, and an electric telescopic rod 433.

[0027] The pressure block 431 is slidably connected inside the support frame 41 and can move up and down in the vertical direction. Its lower end is inverted V-shaped and cooperates with the outer periphery of the steel pipe to achieve self-centering and pressing.

[0028] The buffer plate 432 is fixedly connected to the front and rear sides of the lower end of the pressure block 431. The buffer plate 432 extends along the two inclined surfaces of the inverted V shape, so that the clamping force is evenly transmitted to the outer wall of the steel pipe through the buffer plate 432, preventing local indentations and surface damage. The buffer plate 432 is made of rubber, and the pressure block extends out from the front and rear sides to form a complete cover, preventing the end face of the steel pipe from being bumped.

[0029] The main body of the electric telescopic rod 433 is fixedly connected to the front and rear ends of the pressure block 431. The piston end of the electric telescopic rod 433 is connected upward to the upper end of the support frame 41. The two electric telescopic rods 433 extend simultaneously, driving the pressure block 431 and the buffer plate 432 to move downward as a whole. The inverted V-shaped pressure block 431 elastically presses the steel pipe onto the support roller 42 through the buffer plate 432. The two electric telescopic rods 433 retract synchronously, driving the pressure block 431 and the buffer plate 432 to move upward as a whole, thereby releasing the steel pipe.

[0030] In one embodiment of this utility model, such as Figure 5 As shown, the support component 2 includes a guide groove 21, a guide block 22, a connecting block 23, and a support block 24.

[0031] Among them, the guide groove 21 is opened laterally on the front side of the upper end of the support platform 1, providing a lateral sliding track perpendicular to the steel pipe axis for the guide block and the support block 24, so that the support component 2 can move quickly along the steel pipe axis and achieve precise centering and lifting of steel pipes of different diameters.

[0032] The guide block 22 is embedded in the guide groove 21 and forms a sliding fit. It slides laterally along the guide groove 21, driving the support block 24 to move in a direction perpendicular to the axis of the steel pipe.

[0033] The connecting block 23 is fixedly connected to the upper end of the guide block 22 by bolts or welding, and a slot is provided on its top.

[0034] The lower end of the support block 24 is inserted into the slot to form a detachable positioning, and the upper end is provided with an arc-shaped support surface that matches the outer diameter of the steel pipe. Different specifications of support blocks 24 can be quickly replaced to achieve precise lifting of steel pipes of different diameters.

[0035] In an embodiment of this utility model, a through hole is opened in the center of the upper arc support surface of the support block 24 along the vertical direction to avoid interference with the support block when the drill bit is drilling downwards. The support block 24 is made of copper alloy, which has a lower hardness than commonly used galvanized steel pipes, thus dispersing concentrated stress and completely avoiding indentations on the surface of the steel pipe.

[0036] In one embodiment of this utility model, such as Figure 3 As shown, the connecting component 3 includes a support block 31, an adjustment mechanism 32, and a drilling mechanism 33.

[0037] Among them, the support block 31 is installed on the upper rear side of the support platform 1, and the connecting block 23 is fixedly connected to the front end of the support block 31. The support block 31 is used to support the adjustment mechanism 32 and drive the rotating component and the support component 2 to move laterally in sync.

[0038] Adjustment mechanism 32 is installed at the upper rear of support platform 1. In an embodiment of this utility model, the adjustment mechanism 32 may include a motor, a lead screw, a slider, and a slide groove. The direction of the slide groove is consistent with the direction of the guide groove 21. The slider is slidably connected inside the slide groove and is fixedly connected to the lower end of the support block 31. The slider and the lead screw are threadedly engaged. The motor drives the lead screw to rotate, and the lead screw drives the slider threadedly engaged with it to move under the lateral guidance of the slide groove. The slider drives the support block 31 fixed on it to move horizontally in sync, realizing precise lateral linkage between the support component 2 and the drilling mechanism 33. A telescopic bellows cover is installed inside the slide groove to prevent iron filings from entering.

[0039] The drilling mechanism 33 is installed at the front end of the support block 31.

[0040] In an embodiment of this utility model, the drilling mechanism 33 can move up and down under the lifting drive, and at the same time, the drill bit is driven to rotate by the rotary motor to realize the up and down feeding and drilling operation of the steel pipe.

[0041] In one embodiment of this utility model, such as Figure 2 As shown, chip removal grooves 5 are opened on both sides of the lower end of the guide groove 21 to remove iron chips generated during the drilling process.

[0042] Support legs 6 are symmetrically fixedly connected to the lower end of the support platform 1 to support the entire device horizontally. Chip collection boxes 7 are inserted into the inner sides of the two opposing legs 6. The chip collection boxes 7 are directly below the chip discharge groove 5 and are used to collect iron chips falling from the chip discharge groove 5.

[0043] Specifically, when relevant personnel need to drill holes in steel pipes, they first measure the diameter and wall thickness of the steel pipes. Based on the measurement results, a copper support block 24 is selected. The diameter of the upper arc surface of the support block 24 is the same as that of the steel pipe, and its lower end dimension is consistent with the slot. The support block 24 is aligned and inserted into the slot. The self-locking structure inside the slot conveniently locks the support block 24, completing the quick installation of the support block 24. At this time, the center of the through hole opened at the upper end of the support block 24 coincides with the axis of the drill bit, ensuring accuracy in the subsequent lifting process. At the same time, the axis of the upper arc surface of the support block 24 coincides with the axis of the steel pipe after it is fixed, ensuring that the lifting force is evenly distributed radially along the steel pipe, preventing force eccentricity and local deformation.

[0044] One end of the steel pipe is placed inside the support frame 41 on one side, and the other end of the steel pipe falls into the V-shaped positioning hole. It is supported by two support rollers 42. Then, the steel pipe is pushed and, supported by the rotatable support rollers 42, one end of the steel pipe is inserted into the support frame 41 on the other side. At this time, this end is supported by the support rollers 42. Both ends of the steel pipe are positioned through the V-shaped positioning holes to ensure that the steel pipe is placed horizontally.

[0045] After the steel pipe is placed, two sets of electric telescopic rods 433 are activated simultaneously. According to the diameter of the steel pipe, the electric telescopic rods 433 drive the pressure block 431 to move downward by a set distance. After the buffer plate 432 is attached to the upper end of the steel pipe, it is elastically compressed due to the movement of the pressure block 431. The steel pipe is supported by the V-shaped support roller 42 and pressed by the V-shaped buffer plate 432, forming a four-point self-centering clamping to prevent the steel pipe from jumping or swaying during drilling. At the same time, the support roller 42 wrapped with soft material and the soft buffer plate 432 prevent indentations from forming on the surface of the steel pipe.

[0046] Then, the motor and lead screw in the adjusting mechanism 32 drive the slider and support block 31 to move laterally, so that the axis of the drill bit is aligned with the position of the first hole. When the support block 31 moves, it drives the connecting block 23 fixedly connected to its front end to move synchronously in a straight line. Under the support and guidance of the guide groove 21 and the guide block 22, the connecting block 23 moves in a straight line at the same speed and in the same direction as the support block 31, so that the support block 24 is always located directly below the drill bit.

[0047] After selecting the drill bit according to the required hole diameter, the system adjusts the rotation speed according to the input drill bit diameter and pipe wall thickness. Then, the rotary motor drives the drill bit to rotate, and the drill bit moves downward quickly through the lifting mechanism. Since the height of the upper end of the steel pipe has been determined by the diameter input in the device control system, the movement of the drill bit slows down when it is about to contact the upper end of the steel pipe, and is adjusted to the drilling speed.

[0048] When the rotating drill bit contacts the upper side wall of the steel pipe, the rotational force generated by the drill bit's rotational cutting creates torque inside the pipe wall. Since the two ends of the steel pipe are clamped by the support roller 42 and the buffer plate 432, a four-point self-centering clamping is formed. Moreover, the support frame 41 and the support platform 1 are rigidly connected as a whole, and the rotational force of the steel pipe is absorbed by the clamping position. The steel pipe does not rotate or rotate axially, ensuring the accuracy of the hole position and the stability of the processing.

[0049] The axial pressure generated when the drill bit moves downward is transmitted downward through the pipe wall. It first acts on the upper arc surface of the support block 24, and the support block 24 transmits the pressure downward. It is then transmitted downward through the connecting block 23, the guide block 22 and the guide groove 21, and finally absorbed by the support platform 1, forming a rigid support circuit to ensure that there is no local deformation of the pipe wall.

[0050] After the drill bit completes drilling the upper side wall of the steel pipe, it moves downward to deburr the hole. Then, the lifting mechanism drives the drill bit to quickly retract upward, lifting it off the pipe wall to a safe height. Based on the hole position set in the program, using the first hole position as the position reference, the adjusting mechanism 32 drives the drilling mechanism 33 to move to the next hole position. The motor drives the lead screw to rotate, causing the slider, support block 31, and drilling mechanism 33 to move laterally to the next hole position. At the same time, the connecting block 23 drives the guide block 22 to slide synchronously inside the guide groove 21, ensuring that the support block 24 follows the drilling mechanism 33 to move directly below the next hole position. After each drilling operation is completed, the program automatically repeats the drilling process to achieve continuous multi-point drilling until all the holes set in the program are processed.

[0051] After all holes have been machined, the lifting mechanism drives the drilling mechanism 33 to the highest position for reset, the electric telescopic rod 433 retracts, driving the pressure block 431 to move upward, the buffer plate 432 releases the steel pipe, and the worker pulls out the machined steel pipe from one end. The device enters the waiting state, ready to process the next steel pipe.

[0052] During drilling, the iron filings that fall into the guide groove 21 are pushed by the guide block 22 and the adjusting mechanism 32 to the chip discharge groove 5, and finally fall into the chip collection box 7, completing the automatic discharge of iron filings without manual intervention.

[0053] To improve the processing efficiency of the equipment, especially when multiple batches of steel pipes of the same specifications need to be processed, an adjustable axial limiting device for the steel pipes is installed at one end of the device. This limiting device automatically positions the clamping position of each steel pipe, ensuring the consistency and repeatability of the processing and enabling rapid processing of multiple batches.

[0054] To further improve the processing efficiency of the equipment and enable it to seamlessly integrate into the production line for fully automated feeding, positioning, drilling, and discharging, feeding and discharging conveyor structures are connected to both ends of the device. These are complemented by a rotating steel pipe structure and end position sensing devices. The operating system is connected to the production line control system, and information such as pipe diameter, pipe wall thickness, and hole position is automatically synchronized with the production line data, achieving fully automated feeding. The device can automatically complete feeding, positioning, drilling, and discharging, further improving production efficiency and achieving seamless integration with the production line.

[0055] In summary, the steel pipe drilling device of this utility model can complete continuous multi-point drilling within the clamping section in one clamping operation. The follow-up lifting is always located directly below the drill bit, which avoids the thin-walled steel pipe from bending, denting or breaking due to excessive span. The synchronous clamping and elastic pressing structure at both ends ensures the accuracy of the hole position.
